The DO-214AA SMB package is surface-mount, rated for operating junction temperatures from -55°C to 150°C. This part is a general-purpose transient suppressor for DC power buses, I/O lines, and low-voltage supply rails in industrial, telecom, and automotive-adjacent environments. The 22 V reverse standoff voltage means the diode does not conduct at normal rail levels up to 22 V. Breakdown starts at 24.4 V minimum, so a 24 V regulated bus is too close — this part is sized for a 22 V or lower rail. The 35.5 V clamping voltage at 17.7 A peak pulse current gives the protected circuit a hard ceiling; downstream components need a voltage rating above that clamp level to survive a strike.","metaTitle":"STMicroelectronics SMBJ22A-TR TVS Diode, 600W, DO-214AA","metaDescription":"STMicroelectronics SMBJ22A-TR TRANSIL™ TVS diode, 600W peak pulse power, 22V standoff, 24.4V breakdown, DO-214AA SMB.
