The DO-201 body is 5.3 mm diameter with 25.4 mm lead spacing — the axial leads require a 1.2 mm hole diameter on the PCB, and the copper pad area under the body sets the thermal impedance for pulse dissipation. ## Clamping performance and surge rating The reverse standoff voltage is 8.55 V, and breakdown occurs at 9.5 V minimum — this means a 12 V rail sees no clamping during normal operation, but a transient above 9.5 V triggers the avalanche and the diode shunts the surge to ground before the downstream IC sees the 14.5 V clamp. For new designs, consider the 1.5KE10CA (bidirectional) or a current-production equivalent from the same 1.5KE family, but verify the clamping and standoff match the BOM requirement.","metaTitle":"1.5KE10A-T Diodes Inc Zener TVS, 1500W, DO-201","metaDescription":"Obsolete 1.5KE10A-T Zener TVS diode, 1500W peak pulse, 14.5V clamping, DO-201 axial.
