Descripción general

Description

SMBJ5339B-TP is a surface-mount transient voltage suppressor (TVS) diode in the SMB package. It provides fast, bidirectional protection against voltage transients and ESD on power rails or signal lines.
Key points:
- B = bidirectional operation (clamps both polarities)
- -TP likely indicates tape-and-reel packaging for automated assembly
- Designed to limit voltage spikes by switching to a low-impedance state during surges
What to look up in the datasheet:
- Vrwm/Vbr (stand-off and breakdown voltages)
- Vclamp at a specified current
- Ipp (peak pulse current)
- Leakage, capacitance, and operating temperature range
Common uses:
- USB, data lines, and other high-speed interfaces
- Power rails in consumer, industrial, and automotive electronics
- Any circuit requiring protection from transient surges and ESD
For exact electrical ratings and packaging details, consult the manufacturer’s datasheet for SMBJ5339B-TP.

Features

Here are the key features of SMBJ5339B-TP:
- Bidirectional transient voltage suppressor (TVS) diode (SMBJ series)
- SMB package (DO-214AB); -TP denotes Tape & Reel packaging
- 600 W peak pulse power rating (10/1000 µs waveform)
- Very fast protection (fast response time, sub-ns)
- RoHS compliant; suitable for rugged environments
- Wide operating temperature range (-55°C to +150°C)
- Designed for AC/DC line and data-line protection in automotive, telecom, and industrial applications
Note: Exact voltage ratings (standoff, breakdown, clamp) are per datasheet; check for precise values for your application.

Package

SMBJ5339B-TP uses the SMBJ/DO-214AA (SMB) package. The “-TP” suffix denotes Tape-and-Reel packaging.

Pinout

Pin count: 2 (SMB/DO‑214AA package — anode and cathode).
Function: SMBJ5339B-TP is a two‑terminal TVS (transient voltage suppression) diode used to protect circuits from voltage transients (surge, lightning, ESD). It clamps/limits overvoltage spikes to a safe level; unidirectional parts have defined polarity (anode/cathode), while bidirectional versions are non‑polar. Check the specific datasheet for exact polarity and clamping/standoff voltage ratings.

Manufacturer

Manufacturer: Vishay Intertechnology, Inc.
What kind of company: A global electronics components company that designs and manufactures semiconductors and passive components (e.g., diodes, resistors, capacitors, inductors) for automotive, industrial, consumer, and communications markets.

Application

SMBJ5339B-TP is a surface-mount TVS diode used to clamp transient overvoltages and ESD on DC rails and I/O lines. Applications: automotive electronics (load-dump and 12 V transients), consumer/industrial power supplies, and protection for data interfaces (USB, Ethernet, HDMI, RS-232) and other communications lines. It safeguards CMOS/microcontrollers/ICs from surges in telecom, industrial, and consumer equipment. Packaged in SMBJ with tape-and-reel (TP).

Equivalent

I don’t have enough info to give accurate equivalents. Please provide the manufacturer or the chip’s key specs (unidirectional/bi, standoff voltage VRWM, breakdown/clamping voltages, package SMBJ). With that I can list direct cross‑references.
