500 W peak pulse, 7.5 V standoff — bidirectional Zener TVS in DO-214AC
The 7.5 V reverse standoff voltage means it clamps on a 7.5 V nominal rail, with a minimum breakdown of 8.33 V and a maximum clamping voltage of 12.9 V at the peak pulse current of 38.8 A. The bidirectional channel eliminates orientation concerns on AC or bipolar signal lines.
Clamping voltage and pulse current — what they mean for rail protection
The 12.9 V clamping ceiling at 38.8 A peak pulse current sets the voltage stress the downstream circuitry must survive during a transient. For a 7.5 V supply, the clamp sits about 5.4 V above the rail — typical for a 500 W TVS at this voltage class.
Active production — tape & reel for volume assembly
Microchip lists the SMAJ7.5CAE3/TR13 as Active, meaning ongoing production with no announced end-of-life.
