1500 W unidirectional TVS in DO-201AE
The 1.5KE36A-TP is a 1500 W peak-pulse-power unidirectional TVS diode from Micro Commercial Co, housed in a DO-201AE axial-lead through-hole package.
Clamping and breakdown margins
The reverse standoff voltage is 30.8 V, meaning the diode draws negligible leakage below this level and the protected rail sees no loading during normal operation. Breakdown is guaranteed between 34.2 V minimum and the datasheet maximum, so the device starts conducting before the rail exceeds the safe operating area of downstream silicon. At the full 1500 W peak pulse, the voltage is clamped to 49.9 V maximum. That 19.1 V window between standoff and clamp is the energy the TVS absorbs, and the 49.9 V ceiling determines the voltage stress the load sees during the transient. With a single unidirectional channel, this part protects one polarity — typically a positive rail referenced to ground.
