1500W peak pulse in a DO-214AB footprint
The 1.5SMC16AHE3/57T: It clamps a 66.7 A surge to 22.5 V maximum, protecting downstream silicon from transients on automotive power rails. Reverse standoff is 13.6 V, with a minimum breakdown of 15.2 V — the part sits on a nominal 12 V or 13.6 V bus and starts conducting when the line exceeds the breakdown threshold.
AEC-Q101 and the temperature envelope
Qualified to AEC-Q101, the automotive-grade IC stress qualification standard, and rated for junction temperatures from -65 °C to 150 °C. This is the full under-hood and engine-bay temperature band — a 12 V battery line in a passenger compartment or an ECU supply sees this range without derating the TVS. The TransZorb® series uses a rugged silicon avalanche structure that handles repetitive surges within the 1500 W peak pulse envelope. Power line protection is not specified — this is a signal or low-power rail clamp, not a mains-side suppressor.
Sourcing and compliance posture
Sourced through authorized and independent distribution channels. The part ships in tape-and-reel (TR) format, DO-214AB (SMC) package, suitable for automated pick-and-place assembly.
