Product details
Overview
SMBG100AHE3/5B 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 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMBG100AHE3/5B datasheet, SMBG100AHE3/5B pinout, SMBG100AHE3/5B application, or SMBG100AHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to respond within picoseconds to transients induced by inductive load switching or ESD events. Its cathode-band polarity marking enables correct orientation during layout, and it delivers stable clamping performance up to 150 °C junction temperature.
The SMBG100AHE3/5B is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits 100 °C/W typical junction-to-ambient thermal resistance (RθJA), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-reliability automotive and industrial reflow processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - ensures reliable turn-on above system nominal voltage with margin |
| VC @ IPPM | 162 V at 3.7 A - limits downstream voltage stress during 600 W transient events |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, supporting IEC 61000-4-5 compliance |
| IFSM | 100 A - withstands single 8.3 ms half-sine surge without degradation, critical for automotive load-dump immunity |
| Junction Temp | -55 °C to +150 °C - enables operation in under-hood automotive and industrial ambient environments |
| MSL Level | Level 1 (J-STD-020) - supports standard reflow without dry-pack or baking requirements |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing leadframe with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side reference | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit point in forward bias; marked with band; connects to protected line (e.g., 12 V rail) | Defines polarity-sensitive placement; incorrect orientation disables clamping function |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives |
| 600 W peak pulse power | Supports protection against severe transients such as ISO 7637-2 Pulse 5a (load dump) in 12 V systems |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream ICs like CAN transceivers or microcontrollers |
| MSL Level 1, 260 °C peak | Enables direct placement into standard lead-free reflow profiles without preconditioning |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|

Use Value: Low-profile SMBG package fits tight board spaces; RoHS-compliant HE3 suffix satisfies environmental compliance for CE-marked devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/5B | Same VWM (100 V), but lower PPPM = 600 W (same), higher VC = 170 V at 3.5 A; not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| SMCJ100AHE3/5B | Same VWM/VBR, but larger SMC (DO-214AB) package; PPPM = 1500 W; VC = 165 V at 9.1 A | Higher power handling but 2× footprint; requires more PCB area and thermal relief | Choose when system-level surge threat exceeds 600 W or when derating margin demands ≥1500 W capability |
Compared with SMBJ100A-E3/5B, SMBG100AHE3/5B offers AEC-Q101 qualification and tighter VC; versus SMCJ100AHE3/5B, it trades power headroom for space-constrained layouts - making SMBG100AHE3/5B optimal for automotive modules where footprint and qualification are jointly critical.

FAQ
What is the clamping voltage of SMBG100AHE3/5B at its rated peak pulse current?
The SMBG100AHE3/5B has a maximum clamping voltage (VC) of 162 V at 3.7 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuits during transient events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMBG100AHE3/5B achieves this with low incremental surge resistance, contributing to consistent clamping behavior across temperature and lifetime.
Is SMBG100AHE3/5B suitable for automotive applications?
Yes, SMBG100AHE3/5B is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per the automotive reliability standard. Its -55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and 100 A IFSM rating make it appropriate for under-hood and body-control module applications. The SMBG100AHE3/5B is explicitly listed in Vishay's AEC-Q101 qualified devices table with suffix HE3 denoting this qualification.
What does the "HE3" suffix indicate in SMBG100AHE3/5B?
The "HE3" suffix in SMBG100AHE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification and industrial-grade reliability. Per Vishay's ordering nomenclature, "HE3" denotes matte tin-plated leads, halogen-free molding compound, and full qualification to AEC-Q101 - distinguishing it from "E3" (RoHS, non-automotive) and "HM3" (halogen-free + AEC-Q101). This suffix directly confirms the SMBG100AHE3/5B meets automotive supply chain requirements for traceability and process control.
How does SMBG100AHE3/5B differ from SMBJ100A in physical layout and electrical performance?
SMBG100AHE3/5B uses the smaller SMBG (DO-215AA) package (5.97 mm × 4.06 mm), while SMBJ100A uses SMB (DO-214AA) (4.57 mm × 3.94 mm) - differing in lead pitch and body height. Electrically, SMBG100AHE3/5B has VC = 162 V at 3.7 A, whereas SMBJ100A specifies VC = 170 V at 3.5 A. Crucially, only SMBG100AHE3/5B carries AEC-Q101 qualification. Both share 100 V VWM, but the SMBG100AHE3/5B's tighter thermal resistance (RθJL = 20 °C/W) supports better power dissipation in compact layouts.
Can SMBG100AHE3/5B be used in bidirectional configurations?
No, SMBG100AHE3/5B is a unidirectional TVS diode, as confirmed by its part number structure (no "CA" suffix) and datasheet designation. Bidirectional variants in the same family use the "CA" suffix (e.g., SMBG100CA). Attempting to use SMBG100AHE3/5B for bidirectional protection would result in forward conduction during negative transients, potentially damaging the device or failing to clamp. For bidirectional applications, select SMBG100CAHE3/5B or equivalent - the SMBG100AHE3/5B is strictly intended for polarity-defined DC line protection.
