Product details
Overview
SMBG130AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power electronics, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the SMBG130AHE3/5B datasheet, SMBG130AHE3/5B pinout, SMBG130AHE3/5B application, or SMBG130AHE3/5B equivalent, key selection criteria include clamping performance under surge conditions, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 100 °C/W), unidirectional polarity marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), while low incremental surge resistance enables effective energy absorption during transients like ISO 7637-2 load dump or IEC 61000-4-5 surges.
The SMBG130AHE3/5B is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and carries AEC-Q101 qualification - confirming reliability for under-hood automotive applications where thermal cycling and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 144 V / 159 V at 1 mA - defines reliable avalanche initiation threshold across manufacturing lot |
| VC @ IPPM | 209 V at 2.9 A - clamping voltage during full 600 W surge, limiting stress on protected ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, duty cycle ≤ 0.01 % |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine), relevant for fault-current limiting |
| TJ max | +150 °C - maximum junction temperature, enabling operation in high-ambient environments |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 5.0 mm × 5.0 mm pads, guides heatsinking needs |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing leadframe with matte tin-plated terminals solderable per J-STD-002. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage event |
| Anode (unbanded end) | Reference/return path | Typically tied to system ground or low-impedance return plane to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1.0 µA) over lifetime and temperature |
| 600 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation |
| MSL Level 1 rating | Supports single-reflow assembly at 260 °C peak without popcorn or delamination risk |
| Low profile SMBG package | Enables compact layout in space-constrained modules like ADAS ECUs and battery management systems |
Applications

Use Value: Limits transient overshoot to 209 V, preventing gate oxide rupture and input capacitor overvoltage failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Same VWM/VBR/VC specs but lower PPPM (600 W same), different package (SMB vs SMBG); RθJA = 110 °C/W | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select if automotive qualification is not required and existing SMB footprint is preferred |
| SMCJ130AHE3/5B | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VBR, VC = 219 V at 6.8 A | Used where higher surge margin is needed (e.g., alternator output lines), but requires larger PCB area | Choose when system-level surge testing exceeds 600 W requirements and board space allows SMC footprint |
Compared with SMBJ130A-E3/52 and SMCJ130AHE3/5B, the SMBG130AHE3/5B uniquely balances AEC-Q101 compliance, 600 W capability, and compact SMBG footprint - making it optimal for space-constrained automotive modules requiring validated reliability without overengineering.

FAQ
What is the clamping voltage of SMBG130AHE3/5B and how is it measured?
The SMBG130AHE3/5B has a maximum clamping voltage (VC) of 209 V, measured at a peak pulse current (IPPM) of 2.9 A using a 10/1000 µs double-exponential waveform. This value reflects worst-case voltage seen by protected circuitry during a standardized surge event and is guaranteed across temperature and production lots per Vishay's 88456 specification.
Is SMBG130AHE3/5B suitable for automotive applications?
Yes, SMBG130AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, MSL Level 1 reflow compatibility, and -55 °C to +150 °C operating range - meets stringent automotive reliability requirements for engine control, body electronics, and ADAS subsystems.
What does the "HE3" suffix indicate in SMBG130AHE3/5B?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. It distinguishes this variant from industrial-grade "E3" or halogen-free "HM3" versions in the SMBG family.
How does SMBG130AHE3/5B differ from bidirectional TVS diodes like SMBG130CA?
SMBG130AHE3/5B is unidirectional and features a cathode band for polarity-sensitive placement; SMBG130CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The unidirectional SMBG130AHE3/5B offers lower leakage and is preferred for DC rail protection, whereas SMBG130CA suits AC-coupled or differential signal lines.
What PCB pad layout is recommended for optimal thermal performance of SMBG130AHE3/5B?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal for SMBG130AHE3/5B to achieve the published RθJA of 100 °C/W. Using smaller pads increases thermal resistance, raising junction temperature during surge events and potentially degrading long-term reliability.
