New Bidirectional TVS Diode for 240V Surface Mount Applications

Bourns, a leading manufacturer in the electronics industry, has recently introduced a groundbreaking product - the industry’s first 240 V/1 kA bidirectional power TVS (PTVS) diode in a surface mount package. Known as the Bourns Model PTVS1-240C-M, this bidirectional TVS diode boasts an impressive 1 kA surge handling capability under 8/20 µs test conditions.

Designed specifically for systems with high-voltage DC bus architectures, the bidirectional diode targets applications that frequently encounter high current switching transients and dynamic load behaviors. These scenarios often require snubbing or protection of bus-powered subsystems, making the Bourns Model PTVS1-240C-M an ideal solution for industrial power systems, motor controllers and inverters, solar inverters, battery energy storage systems, and factory automation.

Moreover, Bourns has also unveiled its first SiC Schottky Barrier Diodes, further expanding its product portfolio to meet the evolving needs of the electronics market. The low-leakage bidirectional TVS diode consumes a mere 10 µA in standby mode while offering a maximum breakdown voltage of 295 V, a repetitive standoff voltage of 240 V, and a precise clamping voltage of 340 V.

Under 10/350 µs conditions, the device is rated for an impressive 200 A peak current, with its voltage breakdown sensitivity over temperature exhibiting an extremely linear 0.1 %/°C. The surface mount package not only provides a significantly reduced PCB footprint but also offers lower inductance design advantages compared to traditional through-hole mounted Power TVS Diodes.

The Bourns Model PTVS1-240C-M is now available in the market, boasting UL497B certification and compliance with IEC 61000-4-5 standard specifications. Additionally, the diode is RoHS compliant and halogen-free, aligning with modern environmental standards. For more information on this innovative product, visit Bourns' official website.
