Product details
Overview
SMBG10HE3/52 from Vishay General Semiconductor is a uni-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) 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 (IPPM), and 600 W peak pulse power capability with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs.
For engineers reviewing the SMBG10HE3/52 datasheet, SMBG10HE3/52 pinout, SMBG10HE3/52 application, or SMBG10HE3/52 equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, bi-directional-capable family compatibility (though this part is uni-directional), and RoHS-compliant HE3 whisker-tested terminations.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (< 5 µA leakage at 10 V), then rapidly avalanches to clamp transients above VBR. Its glass-passivated junction ensures stable breakdown and fast response time (< 1 ns), while the DO-215AA package provides low thermal resistance (RθJL = 20 °C/W) for reliable energy dissipation during repetitive surges.
The SMBG10HE3/52 is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports MSL Level 1 handling (260 °C reflow peak), and meets UL 497B recognition for telecom and industrial protectors. Its design targets systems requiring automotive-grade reliability without derating up to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before significant leakage; defines safe working range on protected line. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - tight breakdown tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 17.0 V at 35.3 A - clamping voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 600 W - peak pulse power handling capacity; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω). |
| TJ max | +150 °C - maximum junction temperature; supports operation in engine bay or under-hood automotive environments. |
| IFSM | 100 A - single half-sine surge rating; withstands load dump events in 12 V vehicle electrical systems. |
| Leakage ID | 5.0 µA max at VWM - ultra-low standby current preserves battery life in always-on automotive modules. |
Pinout & Package
DO-215AA (SMBG) surface-mount package: gull-wing leads, matte tin-plated, compliant with J-STD-002 solderability and JESD 22-B102. Cathode indicated by band on body; polarity-critical for uni-directional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during positive transients. |
| Cathode | High-side input terminal | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs when voltage exceeds VBR relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Enables standard SMT reflow without moisture sensitivity concerns - no baking required prior to assembly. |
| UL 497B recognized | Approved for use in telecom and industrial signal-line protectors per Underwriters Laboratories standards. |
| Low Rsurge | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, inductive switch-off), improving system immunity. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Same VWM (10 V), identical DO-214AA package, but lower PPPM (400 W vs. 600 W) and higher VC (18.2 V vs. 17.0 V). | Limited to lower-energy surge environments (e.g., IEC 61000-4-5 Level 3); not recommended for automotive load dump. | Select SMBG10HE3/52 where 600 W rating and AEC-Q101 compliance are mandatory. |
| 1.5SMC10A | Same VWM and VBR range, but larger DO-214AB (SMC) package, higher thermal mass, and 1500 W PPPM rating. | Suitable for high-power industrial motor drives; requires larger PCB area and different pad layout. | Choose SMBG10HE3/52 when space-constrained SMT placement and automotive qualification are priorities. |
Compared with SMBJ10A-E3/52 and 1.5SMC10A, the SMBG10HE3/52 delivers optimal balance of compact DO-215AA footprint, 600 W surge capability, and AEC-Q101 validation - making it the preferred choice for space-limited automotive and industrial modules requiring certified reliability.

FAQ
What is the clamping voltage of SMBG10HE3/52 and why does it matter?
The SMBG10HE3/52 has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (10/1000 µs waveform). This value defines the highest voltage that will appear across the protected circuit during a surge event - critical for ensuring downstream components like MCUs or transceivers remain within their absolute maximum ratings. A lower VC directly improves system-level surge immunity.
Is SMBG10HE3/52 suitable for bi-directional transient protection?
No - SMBG10HE3/52 is a uni-directional TVS diode, indicated by the "A" suffix (not "CA"). It protects only against positive-going transients relative to ground. For bi-directional protection (e.g., AC lines or differential signals), a part with "CA" suffix such as SMBG10CA must be used. The SMBG10HE3/52 datasheet explicitly specifies uni-directional polarity and cathode band marking.
Does SMBG10HE3/52 require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Smaller pads increase thermal impedance and reduce surge capability. The DO-215AA footprint must follow the exact pad dimensions and solder mask clearance shown in the official package drawing to maintain MSL Level 1 compliance and mechanical reliability.
How does the HE3 suffix differ from E3 in SMBG10HE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance (vs. Class 1A for "E3"). This makes SMBG10HE3/52 suitable for automotive under-hood applications where extended temperature cycling and long-term reliability are mandatory - whereas E3 variants are commercial-grade and lack automotive qualification.
Can SMBG10HE3/52 replace SMBJ10A in an existing design?
Not without validation - although both share 10 V VWM and similar VBR, the SMBG10HE3/52 uses DO-215AA (SMBG) while SMBJ10A uses DO-214AA (SMB), resulting in different land patterns, thermal performance, and mechanical fit. Additionally, SMBG10HE3/52 offers higher PPPM (600 W vs. 400 W) and lower VC (17.0 V vs. 18.2 V), which may affect system-level surge margin and layout. Direct replacement requires PCB revision and requalification.
