Unidirectional transient voltage suppressor diode in a JEDEC DO-214AA (SMB) surface-mount package. It is rated for 600 W peak pulse power on a 10/1000 µs waveform and provides a 51 V reverse standoff voltage. The SMBJ51A has a breakdown voltage range of 56.7 V to 62.7 V and a maximum clamping voltage of 82.4 V at 7.3 A peak pulse current. The device uses a glass-passivated junction, offers low incremental surge resistance, and supports a peak forward surge current of 100 A for unidirectional operation. Operating junction and storage temperature range is -55 °C to +150 °C.
