The clamping voltage at that peak pulse current is 64.8 V, which is the voltage the diode holds the protected rail to during the surge. Reverse standoff voltage is 40.2 V — this is the DC or peak-AC voltage the diode can sit across without conducting appreciable leakage. The breakdown voltage range starts at 44.7 V minimum, so the diode begins to avalanche between 44.7 V and the clamping point. For a 36 V or 40 V rail, this part holds the line without interfering with normal operation. ## DO-201 axial — board-fit and temperature range Supplied in a DO-201AA / DO-27 axial leaded package, through-hole mount. The DO-201 body handles the 1500 W pulse without cracking the epoxy — the lead frame and die bond are sized for the thermal shock of a surge. The part is unidirectional (single-channel cathode-band marked). No power line protection built in — this is a signal or low-voltage DC rail protector, not a mains-side MOV replacement. The Tape & Reel packaging suits automated insertion for volume builds. ## Active production — sourcing posture Lifecycle status is Active per Taiwan Semiconductor.","metaTitle":"1.5KE47A R0G TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE47A R0G Zener TVS diode, 1500W peak pulse, 40.2V reverse standoff, 64.8V clamping.
