Active production — no design-in risk
The 1.5SMC11CA-E3/9AT: The 1.5SMC11CA-/9AT carries an Active lifecycle status from Vishay.
Pulse power and voltage thresholds
The reverse standoff voltage is 9.4V, meaning the diode starts conducting above that rail voltage; clamp voltage at peak current is 15.6V, so a 12V bus sees the transient clipped below 16V. Bidirectional — one device clamps both positive and negative surges, saving board space over a back-to-back pair.
Surge current and temperature envelope
Peak pulse current is 96.2A at the 10/1000µs test waveform — the diode must absorb this current without exceeding the 150°C junction limit. Operating temperature spans -65°C to 150°C, so it works in outdoor telecom cabinets and under-hood automotive environments where ambient sees -40°C and self-heating adds margin.
DO-214AB package — reflow and footprint
Supplied in DO-214AB (SMC) package, surface-mount, on Tape & Reel. The SMC footprint is standard for 1500W TVS diodes — the large copper tab on the cathode side (anode for the other polarity) carries the surge current into the PCB. Reflow profile follows standard SnPb or Pb-free solder; the package body is rated for 260°C peak.
