Vishay Intertechnology 24V XClampR TVs in SMC and DO-218AB packages offer the lowest clamp ratios in the industry for high power density

MALVERN, Pa., June 14, 2022 (GLOBE NEWSWIRE) — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced three new series of surface-mount XClampR 24V transient voltage suppressors that provide superior power dissipation. high peak pulse equivalent to 7 kW of conventional TVS at 10/1000 μs in the SMC package (DO-214AB) and 10/10,000 μs in the DO-218AB. Bi-directional devices offer high power density over a wide operating temperature range of -55 C to +175 C for automotive, telecommunications and industrial applications.

With a low clamping voltage of 24 V maximum, the XMC7K24CA series devices provide higher peak impulse 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 maximum clamping voltage of 26 V, the XLD5A24CA and XLD8A24CA series offer Ippm of 120 A and 180 A at 10/10,000 μs, equivalent to the 4.6 kW and 7 kW power ratings of conventional TVS, respectively, in the DO-218AB package.

Suitable for high-reliability applications, Vishay General Semiconductor TVs on the market today are available in AEC-Q101 qualified versions and offer extremely stable breakdown voltages of 26.7 V to 29.5 V over their entire temperature range from functioning. Designed to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning, TVS are intended for automotive load discharge protection and signal line protection in industrial robot arms and telecommunications systems.

For applications with safety voltages greater than 24V, such as 48V belt-start (BSG) and integrated starter (ISG) generators in mild hybrid electric vehicles (HEV), XLD5A24CA series devices, XLD8A24CA and XMC7K24CA can be daisy-chained. with a standard TV. The devices are RoHS compliant and halogen free, and they offer Moisture Sensitivity Level (MSL) of 1 per J-STD-020, 245 C maximum LF peak.
