Obsolete — sourcing through independent channels
The 1.5KE13CAHE3/51 is officially obsolete per Vishay's lifecycle status. Available through independent distribution on a quoted-to-order basis.
AEC-Q101 automotive transient protection, 1500 W pulse
This is a single-channel bidirectional Zener TVS diode from Vishay's TransZorb® series, qualified to AEC-Q101 for automotive-grade reliability screening. The 11.1 V reverse standoff voltage sits below the nominal 12 V battery rail, so the diode remains non-conducting under normal operating conditions. Breakdown occurs at 12.4 V minimum, and clamping is specified at 18.2 V maximum across the bidirectional channel — symmetric protection for AC-coupled or polarity-independent transient paths.
Through-hole DO-201AA axial package, wide temperature range
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the device suits point-to-point wiring, terminal block termination, or PCB through-hole mounting where wave-solder or hand-solder assembly is used. The operating temperature range spans -55°C to 175°C, covering under-hood and engine-compartment thermal profiles without derating. Power line protection is not supported — the diode is intended for signal and low-power supply rail clamping, not AC mains or high-energy direct power line suppression.
