Product details
Overview
SMBG10AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMBG10AHE3/5B datasheet, SMBG10AHE3/5B pinout, SMBG10AHE3/5B application, or SMBG10AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 10 V and rapidly transitions to low-impedance conduction above VBR = 11.1–12.3 V to divert transient energy. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMBG package supports 100 A IFSM (8.3 ms half-sine) and meets MSL Level 1 reflow requirements up to 260 °C.
The device is rated for -55 °C to +150 °C operating junction temperature, exhibits ≤1.0 μA reverse leakage at VWM, and delivers consistent clamping performance across repetitive transients at 0.01% duty cycle. Thermal resistance is RθJA = 100 °C/W (on recommended pad layout) and RθJL = 20 °C/W, enabling reliable thermal management in compact 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 |
|---|---|---|---|
| SMBJ10A-E3/52 | Same VWM/VBR/VC, but SMB (DO-214AA) package; lower IFSM = 30 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost or legacy footprint drives preference over automotive qualification and surge margin |
| SMCJ10AHE3/5B | Same VWM/VBR/VC, but SMC (DO-214AB) package; higher PPPM = 1500 W | Overqualified for 600 W needs; larger footprint and higher parasitic inductance | Select only when system-level testing requires >600 W headroom or higher IFSM = 200 A |
Compared with SMBJ10A-E3/52 and SMCJ10AHE3/5B, SMBG10AHE3/5B uniquely balances 600 W surge capability, AEC-Q101 compliance, and compact SMBG footprint - making it optimal for space-constrained automotive modules where both reliability and board area matter.

FAQ
What is the maximum clamping voltage of SMBG10AHE3/5B at its rated peak pulse current?
The SMBG10AHE3/5B has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current of 35.3 A (10/1000 μs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during transient events, ensuring downstream components remain within safe operating limits.
Is SMBG10AHE3/5B suitable for automotive applications?
Yes, SMBG10AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, MSL Level 1 reflow compatibility, and operation from -55 °C to +150 °C - meeting critical requirements for engine control, body electronics, and ADAS subsystems where reliability under thermal and electrical stress is mandatory.
What does the "HE3" suffix indicate in SMBG10AHE3/5B?
The "HE3" suffix in SMBG10AHE3/5B denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. It distinguishes this variant from industrial-grade "E3" parts and halogen-free "HM3" versions - confirming compliance with automotive environmental and reliability standards per Vishay's ordering nomenclature.
How does SMBG10AHE3/5B differ from bidirectional variants like SMBG10CA?
SMBG10AHE3/5B is unidirectional and features a cathode band marking; it conducts only in reverse bias above VBR. In contrast, SMBG10CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional SMBG10AHE3/5B offers lower leakage and tighter VBR tolerance, making it preferred for DC rail protection where polarity is fixed.
What is the thermal resistance of SMBG10AHE3/5B, and how does it affect PCB layout?
SMBG10AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤150 °C under 600 W pulses, designers must ensure adequate copper area and avoid excessive trace length - underscoring the need for adherence to Vishay's recommended pad layout for reliable thermal performance.
