Product details

1.5 kW bidirectional TVS for 48 V automotive bus clamping

The 1.5KE68CHE3/54: The 55.1 V standoff sits above a nominal 48 V bus, so the diode stays transparent during normal operation and only conducts during a transient. Breakdown occurs between 61.2 V (minimum) and the clamp ceiling — this window protects downstream 60 V-rated semiconductors from overvoltage damage.

Obsolete — last-time-buy window closed

Vishay has marked the 1.5KE68CHE3/54 as obsolete. A board spin or qualification may be required.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE68CHE3/54?

A functional equivalent would be a 1.5 kW bidirectional TVS in a DO-201 package with a 55–58 V standoff, but pin-out and electrical characteristics must be verified against the original BOM requirements.
