The 34.2 V minimum breakdown voltage ensures the device stays transparent during normal operation but fires before the downstream silicon's abs-max rating is reached. This is a general-purpose TVS — not intended for power-line protection, but well-suited to DC supply rails, signal lines, and I/O ports in industrial and telecom gear. ## Junction temperature and package constraints The DO-201AA axial package requires a through-hole solder joint — the lead length and board copper area set the thermal impedance for repetitive surge events. The 1500 W rating is a peak pulse rating at a specific waveform; for repetitive transients, the average power dissipation must stay within the package's thermal limits. The axial leaded form factor allows the part to be mounted in a heatsink clip or soldered into a PCB with adequate copper pour for heat spreading.","metaTitle":"1.5KE36A-E3/73 Vishay TVS, 1500W, 30.8V Standoff","metaDescription":"Vishay 1.5KE36A-E3/73 TransZorb® TVS, 1500W peak pulse, 30.8V reverse standoff, 49.9V clamp.
