Product details

1500W peak pulse, AEC-Q101, now obsolete

The Vishay 1.5KE24HE3/54 is a 1500W (1.5kW) peak pulse power Zener TVS diode from the Automotive, AEC-Q101 qualified TransZorb® series. The -55°C to 175°C operating junction temperature range supports deployment in engine bays and other high-ambient environments.

Obsolete — sourcing through independent channels

For existing BOM lines, the part can be sourced through independent surplus and broker channels.

Package and board-fit for legacy designs

The 1.5KE24HE3/54 is supplied in a DO-201AA (DO-27) axial-lead through-hole package. The through-hole mounting suits point-to-point wiring, terminal blocks, or legacy PCB layouts where surface-mount reflow is not available. The axial body is rated for the full 1500W pulse without derating at 25°C lead temperature. The part is unidirectional with a single Zener TVS die.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5KE24HE3/54?

No official successor or pin-compatible direct replacement from Vishay is recorded in the lifecycle data. A functionally equivalent TVS diode with a 19.4V standoff voltage, 1500W peak pulse rating, and DO-201AA package would need to be evaluated against the BOM's clamping and breakdown requirements.

What compliance documentation does Vishay provide for the 1.5KE24HE3/54?

The part carries AEC-Q101 automotive qualification.
