1500 W peak pulse in a DO-214AB footprint
The 1.5SMC16A-E3/57T: It clamps transients at 22.5 V maximum when conducting its rated 66.7 A peak pulse current, and its 13.6 V reverse standoff voltage means the protected rail stays below the conduction threshold during normal operation. Housed in the DO-214AB (SMC) package, it is a surface-mount device suited for general-purpose transient suppression on power rails, signal lines, and DC buses where a single 1500 W device handles the surge without needing a larger footprint.
Clamping voltage and pulse current — the protection envelope
The 22.5 V maximum clamping voltage at 66.7 A peak pulse current defines the voltage the protected circuitry sees during a surge event — a downstream 16 V-rated rail sees a clamped transient well above its normal operating voltage but within the typical MOSFET or IC abs-max rating for short-duration pulses. Operating temperature spans -65 °C to 150 °C junction — the wide range covers cold-start automotive environments and hot industrial enclosures without derating the pulse power capability at the high end.
