The 24 A peak pulse current rating (Ipp at 10/1000 µs) tells you the diode can absorb a 24 A surge without exceeding the 64.8 V clamp — a direct input for fuse coordination and MOV sizing in the same rail. ## Breakdown window and bidirectional clamp Breakdown voltage starts at 44.7 V minimum — this is the knee where the Zener begins conducting. Below that, the 40.2 V standoff rating guarantees the diode stays off the line at nominal bus voltage, drawing only leakage. The 64.8 V clamp is the voltage the load sees during the surge; a downstream 75 V-rated MOSFET has 10 V of headroom. Bidirectional channels: 1. One device clamps both polarities — no need to series two unidirectional parts. This matters for AC-coupled signal lines or DC rails where reverse-voltage events are possible. ## DO-201 axial lead — board-fit reality Through-hole DO-201AA (DO-27, Axial) package. The DO-201 body is 5.3 mm diameter, 7.6 mm long — the leads are 1.0 mm diameter tinned copper. The 1500 W rating assumes the leads are soldered into a PCB with adequate copper area for heat sinking; the junction-to-lead thermal path carries the pulse energy. The 175°C max junction allows the device to absorb repetitive pulses in a hot enclosure — a 105°C ambient still leaves 70°C of junction margin for the pulse.","metaTitle":"1.5KE47CA A0G TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE47CA A0G bidirectional Zener TVS, 1500W peak pulse, 40.2V standoff, 64.8V clamp.
