The 36.8 V reverse standoff voltage means the diode stays transparent on a nominal 36 V bus — it does not conduct until the transient pushes the line above 40.9 V (the minimum breakdown voltage). Below that threshold, the leakage current is negligible for most general-purpose protection circuits. The axial leads require a hole diameter of roughly 1.0 mm on the PCB. Keep the trace width from the protected rail to the anode short and wide — the inductance in a long skinny trace adds voltage drop during the fast rising edge of a 10/1000 µs pulse.","metaTitle":"1.5KE43A R0G TVS Diode, 1500W, 36.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE43A R0G Zener TVS, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamping.
