Product details

Automotive qualification and temperature range

The 1.5SMC39CAHM3/H: Production status is active per the manufacturer.

The copper pad area under the cathode tab sets the thermal resistance; a 1 oz copper pour on the top layer pulls heat into the board. Supplied in Tape & Reel for automated pick-and-place. The bidirectional channel means a single device clamps both polarities — no need to orient the cathode on the PCB.
