SMBJ5.0A-13-F

SMBJ5.0A-13-F is a unidirectional transient-voltage-suppressor (TVS) diode in the SMBJ (DO-214AA) surface-mount package. It protects low-voltage DC rails and data lines from fast transients and ESD by clamping excess voltages to ground. The “5.0A” indicates a nominal reverse-standoff voltage around 5 V; the breakdown voltage (VBR) is higher (typical 6–7 V), with clamping occurring at higher current. The “A” denotes unidirectional operation; “-F” usually means RoHS lead-free; “-13” is a manufacturing/date/variant code used by some vendors. Common applications include 5 V rails (USB, microcontrollers, logic lines), power-supply protection, and general surge suppression on low-voltage lines. When selecting, verify VRRM, VBR, clamping voltage (VCL), peak pulse current (IPP), leakage, junction capacitance, and temperature range from the specific datasheet. Also ensure footprint and soldering compatibility with your PCB.

SMBJ5.0A-13-F is a 5.0 A, unidirectional TVS diode in the SMBJ package with a 13 V stand-off. Equivalents are other 5.0 A, 13 V unidirectional SMBJ TVS diodes from major vendors. Common cross-references include:
