Product details
Overview
SMBG5.0HE3/5B from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping ESD and surge transients on signal/power lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), 9.2 V clamping voltage at 65.2 A IPPM, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the SMBG5.0HE3/5B datasheet, SMBG5.0HE3/5B pinout, SMBG5.0HE3/5B application, or SMBG5.0HE3/5B equivalent, key selection criteria include bi-directional clamping capability, low clamping ratio (VC/VBR ≈ 1.38), MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<800 μA leakage at 5.0 V), but triggers into low-impedance conduction when reverse or forward transients exceed its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1.0 ps).
The SMBG5.0HE3/5B is rated for -55 °C to +150 °C junction temperature, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance due to HE3 suffix construction.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | Same VWM (5.0 V), identical DO-214AA package, but lower PPPM (600 W same), slightly higher VC (9.6 V) | Non-AEC-Q101; suitable for commercial/industrial only | Select SMBJ5.0CA if automotive qualification is not required and cost optimization is prioritized |
| SAC5.0 | Lower PPPM (400 W), same VWM, SOD-123FL package (smaller footprint, higher thermal resistance) | Limited to low-energy transients; not rated for IEC 61000-4-5 Level 4 | Choose SAC5.0 only for space-constrained consumer designs with sub-300 W surge requirements |
Compared with SMBJ5.0CA and SAC5.0, the SMBG5.0HE3/5B uniquely combines AEC-Q101 qualification, DO-215AA mechanical robustness, and 600 W surge handling in a bi-directional configuration-making it the preferred choice for automotive and high-reliability industrial interfaces where long-term parametric stability and MSL Level 1 process compatibility are mandatory.

FAQ
What is the clamping voltage of SMBG5.0HE3/5B at its rated peak pulse current?
The SMBG5.0HE3/5B has a maximum clamping voltage (VC) of 9.2 V at its rated peak pulse current (IPPM) of 65.2 A under the standard 10/1000 μs waveform. This value is measured with the device mounted on 5.0 mm × 5.0 mm copper pads per terminal, ensuring realistic thermal dissipation during surge events. The SMBG5.0HE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG5.0HE3/5B suitable for bi-directional signal line protection?
Yes, SMBG5.0HE3/5B is explicitly designed for bi-directional applications, as indicated by its "CA"-equivalent behavior and absence of polarity marking. Its symmetrical breakdown (6.4–7.07 V in both directions) and identical clamping characteristics make it ideal for protecting AC-coupled or differential interfaces such as CAN, RS-485, and USB D+/D− lines. The SMBG5.0HE3/5B does not require orientation during placement.
Does SMBG5.0HE3/5B meet automotive reliability standards?
Yes, the "HE3" suffix denotes AEC-Q101 qualification, confirming that SMBG5.0HE3/5B has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. It is rated for operation from -55 °C to +150 °C and qualified for under-hood automotive use. The SMBG5.0HE3/5B also meets JESD201 Class 2 whisker resistance requirements.
What is the maximum leakage current of SMBG5.0HE3/5B at its stand-off voltage?
The SMBG5.0HE3/5B exhibits a maximum reverse leakage current (ID) of 800 μA at its 5.0 V stand-off voltage (VWM), measured at 25 °C. This low leakage ensures minimal impact on battery-powered or high-impedance sensor circuits. Leakage remains within specification up to 125 °C, supporting reliable operation in thermally demanding environments.
