Peak pulse power capability: 5 kW with a 10/1000 μs waveform
Operating junction temperature range: – 65 °C to + 185 °C
Stand-off voltage: 10 V to 43 V
Peak pulse power current: 72 A to 294.1 A
Maximum clamping voltage: 17 V to 69.4 V
Market Applications:
•
Secondary automotive load dump protection and telecom infrastructure DC power bus lightning
surge protection
The Perspective:
Vishay’s new 5KASMC series of TVS in the SMC DO-214AB package offer 233 % higher surge capability
than conventional 1.5 kW devices in SMC packages, increasing design flexibility and compatibility. In
addition, the TVS’ 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.
Availability: Samples and production quantities of the new 5KASMC series are available now, with lead
times of eight weeks for large orders.
