Zener TVS for 8V rail protection
It delivers 1500W peak pulse power per the 10/1000µs waveform, clamping at 15V at the rated 100A peak pulse current.
The reverse standoff voltage is 8V, meaning the diode is effectively open below that level. Breakdown starts at a minimum of 8.89V, giving a 0.89V guard band before the diode begins conducting. At the full 100A peak pulse current, the clamping voltage rises to 15V — that is the voltage the protected circuitry must survive. The 1500W power rating is the product of clamping voltage and peak current, so a lower-current transient will clamp at a lower voltage, but the 15V ceiling is the worst-case design number.
Active production and tape-and-reel availability
The DO-214AB (SMC) package is widely second-sourced, so if a shortage hits, there are mechanically interchangeable alternatives from other brands — though the breakdown and clamping voltages should be cross-checked against the BOM requirement.
The 1500W rating is derated at high temperature per the datasheet curve — at 150°C the peak pulse power drops to about 75% of the 25°C value, so a hot environment reduces the transient headroom. For a 12V automotive battery line, the 8V standoff is too low; this part is aimed at 5V or 8V supply rails, not the battery bus.
