Vishay has introduced a new series of surface-mount PAR transient voltage suppressors (TVS) in the SMC DO-214AB package. For automotive and telecom applications, 5KASMC series devices feature high surge capability to 5 kW at 10/1000 s and an operating junction temperature range from -65°C to +185°C.
The new devices claim to offer 233% higher surge capability than conventional 1,5 kW devices in SMC packages, increasing design flexibility and compatibility. In addition, their high operating junction temperatures and new low-stress, symmetric lead frame designs provide the high reliability required for automotive applications.
Designed to protect sensitive electronic equipment against voltage transients induced by system inductive load switching and lightning, the AEC-Q101-qualified devices are suitable for secondary automotive load dump protection and telecom infrastructure DC power bus lightning surge protection.
The 5KASMC series consists of 16 TVS devices with stand-off voltages from 10 V to 43 V. They offer a peak pulse power current from 294,1 A to 72 A, maximum clamping voltage from 17 V to 69,4 V, very fast response times and low incremental surge resistance.
