Surface Mount XClampRTM Transient Voltage Suppressors Combine High Power Dissipation and Pulse Current with High Temperature Reliability for Automotive and Industrial Applications

Vishay Intertechnology, Inc. has introduced three new series of 24 V surface-mount XClampR transient voltage suppressors (TVS) that are available in AEC-Q101 qualified versions and deliver high power density over a wide operating temperature range of -55 °C to +175 °C for automotive, telecom, and industrial applications. Designed to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning, the TVS are intended for automotive load dump protection and signal line protection in industrial robot arms and telecom systems.

Suitable for high-reliability applications, these bidirectional devices offer high peak pulse power dissipation and extremely stable breakdown voltages from 26.7 V to 29.5 V over their entire operating temperature range. With a low clamping voltage of 24 V maximum, the new XMC7K24CA series devices offer a higher peak pulse current (Ippm) of 180 A at 10/1000 μs, equivalent to the 7-kW power rating of conventional TVS in the SMC package. With a clamping voltage of 26 V maximum, the XLD5A24CA and XLD8A24CA series offer Ippm of 120 A and 180 A at 10/10 000 μs, which is equivalent to the 4.6 kW and 7 kW power ratings of conventional TVS, respectively, in the DO‑218AB package.
