Zener TVS for 15V rail clamping
Its peak pulse power rating of 1500W (1.5kW) under the 10/1000µs waveform gives you a solid margin for industrial surge events, but the clamping voltage at 25V max means the downstream circuitry must tolerate that ceiling. This part is obsolete per onsemi's lifecycle status, so new designs should look at current-generation Zener TVS diodes in the same axial footprint. For legacy BOM maintenance, sourcing through independent distribution is the practical path.
Peak pulse power and clamping behaviour
Rated for 1500W peak pulse power at 10/1000µs, the ICTE-15RL4G can handle a 60A peak pulse current (8/20µs waveform). The breakdown voltage min is 17.6V, and the clamping voltage max is 25V at Ipp. That 25V clamp is the hard limit your downstream silicon must survive — if your 15V rail powers a 20V-tolerant IC, you have headroom; if it's a 16V-rated part, you need a lower-clamp TVS.
onsemi lists the ICTE-15RL4G as obsolete. No official successor is cited in the available records. For existing BOM lines, the practical supply route is independent distribution — we source against your RFQ from our multi-supplier network.
