The 53.6V clamp is the voltage the protected IC must survive — check the absolute-maximum rating of the downstream regulator or transceiver against this value. The 28A peak pulse current at 10/1000µs is the worst-case surge the diode can shunt; if the source impedance is low enough to push more current, a series resistor or a higher-power TVS is needed. The through-hole axial package is a mature form factor — board-level inventory and hand-assembly are straightforward.","metaTitle":"1N6156A Zener TVS Diode – 1500W, 29.7V Standoff, Axial","metaDescription":"1N6156A Zener TVS diode from Microchip Technology. 1500W peak pulse power, 29.7V reverse standoff, 53.6V clamping.
