Above 28.5 V the device starts to break down, and at 41.4 V it hard-clamps the transient — so the protected circuitry must survive that clamp voltage for the pulse duration. A 36 A peak pulse current at the 10/1000 µs test waveform gives the surge capacity for typical industrial transient events like inductive load switching or lightning-induced surges on long cable runs. The 1500 W rating is specified at 25°C; derate above that per the power dissipation curve in the full datasheet. No power line protection feature — this is a standalone transient clamp, not a filtered or coordinated protection IC. ## Obsolete — sourcing through independent channels Diodes Incorporated lists the 1.5KE30CA-T as obsolete. For a BOM line that requires this exact clamp voltage and package, the 1.5KE30CA-T remains orderable against an RFQ. No pin-compatible direct replacement from Diodes Inc is documented; a parametric search for 1500 W bidirectional TVS in DO-201 with 25.6 V standoff and 41.4 V clamp will surface functional equivalents from other brands, but a board spin may be needed if the footprint or lead form differs.","metaTitle":"1.5KE30CA-T Diodes Inc TVS, 1500W, 25.6V Standoff, DO-201","metaDescription":"Diodes Inc 1.5KE30CA-T bidirectional TVS diode, 1500W peak pulse, 25.6V standoff, 41.4V clamp.
