Clamping voltage and peak current — what they mean for a 36 V rail
The SMAJ36CA-13-F: When a transient exceeds the breakdown threshold (40 V min), it clamps at 58.1 V maximum while shunting 6.9 A of peak pulse current (10/1000 µs waveform).
Single bidirectional channel — one device, both polarities
This saves PCB area and reduces component count on bipolar signal lines or DC rails where the polarity can reverse during a fault.
At the high end, the leakage current increases but the clamping voltage remains within spec.
DO-214AC (SMA) — the industry-standard TVS footprint
Housed in the DO-214AC (SMA) package, the SMAJ36CA-13-F uses the same land pattern as hundreds of other 400 W TVS diodes from multiple manufacturers. The SMA package is a surface-mount, small-outline form factor with a gull-wing lead configuration, rated for reflow soldering and compatible with standard pick-and-place equipment.
General-purpose application class — signal and DC rail transient suppression
Marked for General Purpose applications, this TVS diode is intended for transient suppression on DC power rails, digital I/O lines, analog sensor inputs, and communication buses. It is not rated for AC mains power-line protection, so it should be used downstream of the AC-DC conversion stage or on low-voltage DC circuits.
