Product details
Overview
SMBJ6.0-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current.
For engineers reviewing the SMBJ6.0-E3/5B datasheet, SMBJ6.0-E3/5B pinout, SMBJ6.0-E3/5B application, or SMBJ6.0-E3/5B equivalent, key selection criteria include its unidirectional polarity, low clamping voltage, RoHS-compliant matte tin plating, MSL Level 1 rating, and suitability for automotive-grade designs when ordered with HE3 suffix.
Technical Context
This TVS diode operates as a voltage-clamping protection device placed in parallel with vulnerable circuit nodes-such as power rails or signal lines-to shunt transient energy to ground before downstream components experience overvoltage stress. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge conditions.
The SMBJ6.0-E3/5B delivers fast response time (<1 ns), low incremental surge resistance, and thermal stability up to TJ = 150 °C. With RθJA = 100 °C/W and RθJL = 20 °C/W, it supports robust thermal dissipation on standard 0.2" × 0.2" copper pads per terminal, enabling use in space-constrained industrial and automotive PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-M3/5B | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package. | No functional difference; selected where halogen-free material compliance is mandated. | Choose for green manufacturing programs requiring halogen-free bill-of-materials. |
| SMBJ6.0CA-E3/5B | Bidirectional version with same VWM (6.0 V), symmetric VBR (±6.67–7.37 V), and identical PPPM. | Supports AC-coupled or floating signal lines where polarity reversal may occur. | Select when protecting bidirectional buses (e.g., CAN, RS-485) without polarity constraints. |
Compared with SMBJ6.0-E3/5B, the M3 variant adds halogen-free compliance without performance trade-offs, while the CA variant enables polarity-agnostic protection at the cost of slightly higher leakage in some bias conditions-making each suitable for distinct system grounding and regulatory contexts.

FAQ
What is the breakdown voltage range of the SMBJ6.0-E3/5B?
The SMBJ6.0-E3/5B has a guaranteed breakdown voltage (VBR) range of 6.67 V to 7.37 V at a test current of 10 mA, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures reliable turn-on behavior during overvoltage events and supports precise system-level protection design around the 6.0 V stand-off voltage.
Is the SMBJ6.0-E3/5B suitable for automotive applications?
The SMBJ6.0-E3/5B is RoHS-compliant and qualified to MSL Level 1, but it is not AEC-Q101 certified. For automotive-grade use, Vishay offers the SMBJ6.0HE3 variant (with HE3 suffix), which carries full AEC-Q101 qualification. Engineers must select SMBJ6.0HE3 instead of SMBJ6.0-E3/5B when automotive qualification is required.
How does the SMBJ6.0-E3/5B compare to SMAJ6.0A in terms of power handling?
The SMBJ6.0-E3/5B delivers 600 W peak pulse power (10/1000 µs), whereas the SMAJ6.0A is rated for 400 W. The larger SMB package provides superior thermal mass and lower thermal resistance (RθJA = 100 °C/W vs. ~140 °C/W for SMA), making SMBJ6.0-E3/5B better suited for high-reliability, high-surge applications where sustained power dissipation matters.
What is the maximum clamping voltage of the SMBJ6.0-E3/5B under surge conditions?
The SMBJ6.0-E3/5B clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This clamping voltage directly limits the stress imposed on downstream components, making it appropriate for safeguarding 5 V logic circuits, sensor interfaces, and USB power rails.
Does the SMBJ6.0-E3/5B have polarity marking, and how is it identified?
Yes-the SMBJ6.0-E3/5B is unidirectional and features a cathode band on the package body, aligned with the cathode terminal. Per Vishay's mechanical drawing, the banded end corresponds to the cathode, which must be connected toward the positive side of the protected circuit. No marking appears on bidirectional variants like SMBJ6.0CA-E3/5B.
