24V rail clamp with 600W surge rating
Its reverse standoff voltage is 24V, meaning the device does not conduct appreciably below that level, so it sits across the supply without loading it. When a transient exceeds the breakdown threshold (minimum 26.7V,), the diode clamps the surge to a maximum of 38.9V at a peak pulse current of 15.4A.
Package and temperature range for board fit
Housed in a DO-214AA (SMB) surface-mount package, the SMBJ24AE3/TR13 has a junction temperature range of -65°C to 150°C. That industrial-grade span covers outdoor telecom cabinets, engine-bay electronics, and factory-floor equipment without derating concerns. The base product number is SMBJ24, so any SMBJ24A variant shares the same silicon die and electrical characteristics — the A suffix denotes the 5% tolerance on breakdown voltage.
There is no direct successor or replacement — the part is the current offering. For BOM planning, this eliminates the risk of a last-time-buy scramble. The DO-214AA package is widely stocked across the distribution channel, so lead times are typically standard for an active surface-mount TVS. Submit an RFQ for a firm price and delivery commitment.
