Description
SMBJ5339B-TP is a bidirectional transient voltage suppressor (TVS) diode in the SMBJ (DO-214AB) package. It’s used to clamp high-energy voltage transients on lines such as power rails or data interfaces, protecting downstream circuitry from spikes and ESD. The “B” marks bidirectional protection; the “-TP” suffix typically indicates tape-and-reel packaging for automated assembly.
Key points:
- Purpose: surge/ESD protection on sensitive electronics.
- Package: SMBJ, surface-mount, rugged, suitable for automated assembly.
- Variant specifics: VRWM (working reverse voltage), VBR (breakdown), Vclamp, IPP (peak pulse current), leakage, and capacitance—these vary by part and must be checked in the datasheet.
- Selection tip: choose a VRWM above normal operating voltage, and ensure the clamp voltage and energy rating meet your surge environment.
- Applications: power-entry protection, USB/data lines, CAN/Ethernet, automotive and consumer electronics.
For exact electrical numbers and packaging options, refer to the manufacturer’s datasheet.

Pinout
Pin count: 2 pins — anode and cathode (SMB/DO‑214AA package).
Function: It is a TVS (transient-voltage-suppression) diode used to protect circuits from transient overvoltage events (ESD, lightning surges, load dumps) by clamping voltage spikes to a safe level. The “B” typically denotes a bidirectional device (clamps both polarities); “-TP” denotes tape‑and‑reel packaging for automated assembly.
