The SMAJ51A-13-F: Its 56.7 V minimum breakdown ensures the device starts conducting before the protected circuit sees overvoltage, and the 82.4 V maximum clamping at 4.9 A peak pulse current limits the voltage spike the load experiences.
Housed in the standard DO-214AC (SMA) surface-mount package, the SMAJ51A-13-F supports automated assembly and reflow soldering.
Diodes Incorporated is the manufacturer.
The SMAJ51A-13-F is a Zener-type TVS diode, meaning it uses the avalanche breakdown of a Zener junction to clamp voltage transients.
