TDK Corporation (TSE:6762) has expanded its ultra-low clamping voltage TVS diode lineup with three new models in the SD0201 series, tailored for high-speed consumer electronics interfaces. These TVS diodes offer compact protection for USB Type-C, HDMI, DisplayPort, and Thunderbolt connections in smartphones, laptops, tablets, wearables, and networking devices.

Each component comes in a 0201 chip-scale package (CSP), measuring just 0.58 x 0.28 x 0.15 mm (L x W x H) for space-constrained designs. Having working voltages of ±1 V, ±2 V, and ±3.6 V, the new TVS diodes safeguard sensitive circuits from electrostatic discharge (ESD) and transient surges. This means they meet IEC 61000-4-2 standards with ESD discharge robustness up to ±15 kV and support surge current handling up to 7 A, depending on the variant. Their symmetrical design enables bidirectional protection and thus flexible PCB routing, while very low leakage currents and dynamic resistance as low as 0.16 Ω enhance application-level efficiency.

The individual components differ in their DC working voltage and parasitic capacitance: the SD0201SL-S1-ULC101 (ordering code B74121U1036M060) has a working voltage of ±3.6 V and a parasitic capacitance of 0.65 pF, the SD0201-S2-ULC105 (B74121U1020M060) of ±2 V and 0.7 pF, and the SD0201SL-S1-ULC104 (B74121U2010M060) of ±1 V and 0.15 pF. A LTspice model library for SEED simulations for TVS diodes is available for download.

TDK’s new ultra-low clamping voltage TVS diodes are engineered to meet the challenges in today and tomorrow’s consumer electronics, ensuring reliable performance and safeguarding sensitive electronic devices from damaging transients.

TDK Corporation (TSE:6762) presents its new EPCOS B3264xH series of double-sided metallized polypropylene film capacitors (MMKP). These components are designed to meet the demands of high-frequency applications with high pulse stress of up to 6,500 V/µs, where traditional solutions may fall short. They excel in resonant circuits, particularly the popular LLC topology. Due to their compact form factor and AEC-Q200 compliance, these components are generally used in onboard chargers (OBCs) and DC-DC converters in xEVs, as well as in uninterruptible power supplies (UPS), industrial switch-mode power supplies (SMPS), and electronic ballasts.

These capacitors offer a rated DC voltage range from 630 V to 2000 V and cover capacitance values from 2.2 µF up to 470 µF. They are engineered with a special dielectric system combining polypropylene and double-sided metallized PET film, delivering high pulse strength and exceptional current handling capabilities. Rated for continuous operation from -55 °C to +125 °C, the series ensures long-term reliability even under harsh environmental conditions.

The B3264xH capacitors stand out with their high insulation resistance, low dissipation factor, and robust self-healing properties, resulting in a service life of 200,000 hours at +85 °C and full rated voltage. These components are available in three lead spacing variants (10 mm, 15 mm, and 22.5 mm), enabling flexible integration into space-constrained circuit layouts.

By combining high performance with automotive-grade reliability, TDK’s B3264xH series helps designers optimize efficiency and longevity in advanced power electronics systems across both automotive and industrial sectors.

For the B3264xH, corresponding simulation models for various Spice versions and ANYSYS are available for download here.

• Wide frequency range beyond 1 GHz to enable high impedance characteristics
• Reduced footprint by minimizing the number of power-over-coax (PoC) filter inductors to one component
• Suitable for high temperature environments; supports a wide operation range of -55 °C and +155 °C

TDK Corporation (TSE: 6762) has expanded its ADL4524VL series (4.5 x 2.4 x 2.6 mm – L x W x H) of wire-wound inductors for automotive power-over-coax (PoC). Mass production of these components began in July 2025.

With automotive PoC technology, a single coaxial cable can simultaneously carry both power and data. PoC is widely used in automotive camera systems as ADAS for safe driving has become more widespread. Using a single coaxial cable for power and signal lowers the vehicle’s weight by reducing cabling, which in turn helps to improve fuel and power consumption. Simplified cabling within the vehicle also allows for a more effective use of the space.

The PoC system requires a filter incorporating multiple inductors to separate power from the data signal before processing effectively. This product enables high impedance at a wide frequency range from 10 MHz to 1 GHz with its proprietary materials and structural design innovation. This reduces the number of inductors used to save space. By covering a wide frequency range, this product can handle applications with fewer inductors. For example, where conventional solutions might require three inductors, this solution requires only one. The inductor ensures high reliability with an upper operation temperature range limit of +155 °C.

Looking ahead, TDK is committed to developing inductors for automotive PoC applications by pursuing optimized design by refining multilayer, wire-wound, and thin-film technologies to address market needs. TDK will expand its lineup of products to improve the quality of PoC transmission signals.
