Surface-mount transient voltage suppressor diode provides 600 W peak pulse power capability on a 10/1000 µs waveform. The unidirectional device has a 12 V reverse stand-off voltage, 13.3 V to 14.7 V breakdown range, and 19.9 V maximum clamping voltage at 30.2 A peak pulse current. It uses an SMB/DO-214AA package with a cathode color band and is rated for a 150 °C operating junction temperature.
