The 1500 W rating is the peak pulse power at the 10/1000 µs test waveform — derate for shorter pulses or higher ambient temperatures per the TransZorb datasheet curve. ## Obsolete — sourcing through surplus channels Vishay lists this part as Obsolete. The 1.5KE series is broad, but a direct drop-in requires matching the breakdown window, clamping voltage, and bidirectional polarity — a parametric search against the 19.8 V min breakdown and 31.9 V clamp is the starting point for a substitute. Available through independent surplus and broker channels.
