Product details

400W bidirectional TVS — what the ratings mean for your board

The SMAJ75CA-13-F: At a 75V reverse standoff voltage it stays transparent to the protected rail; when a transient exceeds 83.3V (minimum breakdown) the device clamps at 121V maximum, shunting up to 3.3A of surge current away from downstream components.

Housed in a DO-214AC (SMA) package, the SMAJ75CA-13-F is a surface-mount device intended for reflow soldering. The SMA footprint is standard and matches the industry-common DO-214AC land pattern, so no special layout accommodation is needed.

The 150°C upper limit gives headroom for self-heating during repetitive surge events.

Diodes Incorporated lists the SMAJ75CA-13-F as Active in production.
