Space-saving standard rectifier and TVS is a two-in-one solution

Vishay Intertechnology, Inc has introduced a new surface-mount solution for automotive applications, the industry's first standard rectifier and TVS two-in-one device. Providing an oxide planar chip junction design and a common cathode circuit configuration, the Vishay General Semiconductor R3T2FPHM3 combines a 3A, 600V standard rectifier with a 200W TRANSZORB TVS in the compact FlatPAK 5 x 6 package.

With a wide temperature range from -55C to +175C, the device is ideal for high-reliability automotive applications, including secondary protection for sensor units, distributed airbag modules, and low-power DC-DC converters in power distribution systems. By combining two different technologies in a single package, the dual-chip solution saves PCB space, simplifies layouts, and lowers overall costs in these applications. When paired in series with a standard TVS, the device provides designers with a complete >24V solution with a low clamping ratio.

The two-in-one device's rectifier features a low forward voltage drop of 0.86V to reduce power losses and improve efficiency, while its TVS offers a breakdown voltage of 27V. The device provides ESD capability in compliance with IEC 61000-4-2, air discharge and contact mode; it gives an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260C; and its moulding compound features a UL 94 V-0 flammability rating. RoHS-compliant and halogen-free, the device is available in an AEC-Q101-qualified version.
