14V rail Zener TVS — 25.8V clamp in DO-214AA
Its 25.8V maximum clamping voltage at 23.3A peak pulse current (10/1000µs waveform) defines the protection ceiling for downstream components.
Breakdown and clamping — 15.6V min breakdown, 25.8V clamp
Minimum breakdown voltage is 15.6V, ensuring the diode begins conducting before the rail exceeds safe levels. The 25.8V clamp at 23.3A peak current sets the maximum voltage the protected load sees during a surge — a key number for selecting downstream capacitor voltage ratings and semiconductor BVdss margins. Operating temperature spans -65°C to 150°C junction, covering cold-start and under-hood environments without derating the 600W peak pulse capability at elevated temperatures.
Active production — DO-214AA tape-and-reel
Microchip lists the SMBJ14CE3/TR13 as Active.
