Vishay Intertechnology, Inc. has introduced a new surface-mount solution for automotive applications that is the industry’s first standard rectifier and transient voltage suppressor (TVS) two-in-one device.
Featuring an oxide planar chip junction design and a common cathode circuit configuration, the Vishay General Semiconductor R3T2FPHM3 combines a 3 A, 600 V standard rectifier with a 200 W TRANSZORB TVS in the compact FlatPAK 5 x 6 package.
With a wide temperature range from -55° C to 175° C, the new device is suitable for high reliability
Source: Vishay Intertechnology, Inc. 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 R3T2FPHM3 offers designers a complete greater than 24 V solution with a low clamping ratio.
The two-in-one device’s rectifier features a low forward voltage drop of 0.86 V to reduce power losses and improve efficiency, while its TVS offers a breakdown voltage of 27 V. The R3T2FPHM3 provides electrostatic discharge (ESD) capability in compliance with IEC 61000-4-2, air discharge and contact mode; offers a MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260° C; and its molding compound features a UL 94 V-0 flammability rating. RoHS-compliant and halogen-free, the device is available in an AEC-Q101 qualified version.
Samples and production quantities of the R3T2FPHM3 are available now, with lead times of 12 weeks.
