1500W peak pulse, 22.5V clamp — the so-what for your rail
The 1.5KE16CA/B: That 22.5V clamping voltage (max) at 67.6A peak pulse current means a 13.6V nominal rail — 12V or 15V bus — sees the transient clipped before it reaches downstream silicon. The 15.2V minimum breakdown voltage ensures the device triggers before the clamp voltage is reached. Through-hole DO-201AA / DO-27 axial package with a -55°C to +150°C junction temperature range, so it fits high-reliability and industrial environments where board-level surge protection is required.
