The 14 V reverse standoff voltage (VRWM) means the diode draws negligible leakage below that level, so it sits across the supply without loading the rail. When a transient exceeds the 15.6 V minimum breakdown voltage, the diode avalanches and clamps the spike to 25.8 V maximum at 19.4 A peak pulse current.
Package and temperature range for the BOM
Housed in the DO-214AC (SMA) surface-mount package, the SMAJ14E3/TR13 shares the same footprint as many other SMA TVS diodes, so a board layout change is unlikely if you are swapping within the family.
Availability is confirmed per RFQ; we source against your BOM quantity. The DO-214AC package is widely stocked across the distribution channel, so lead times are typically short for active parts in this form factor.
