Product details
Overview
SMBG130A-E3/5B 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 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR at 1 mA), 209 V 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 supply inputs and industrial sensor interfaces.
For engineers reviewing the SMBG130A-E3/5B datasheet, SMBG130A-E3/5B pinout, SMBG130A-E3/5B application, or SMBG130A-E3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and packaging configuration for reliable ESD/surge co-design in high-reliability embedded systems.
Technical Context
The SMBG130A-E3/5B operates as a unidirectional avalanche-clamping device, triggered when reverse voltage exceeds its 144–159 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling suppression of fast transients such as ISO 7637-2 load dump spikes and IEC 61000-4-5 surge events.
Thermally, it uses a low-profile SMBG (DO-215AA) surface-mount package with matte tin-plated leads, rated for MSL Level 1 per J-STD-020 and qualified to AEC-Q101. Junction-to-ambient thermal resistance is 100 °C/W on 0.2" × 0.2" copper pads, supporting sustained operation up to TJ = 150 °C under repetitive surge conditions at ≤0.01% duty cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG130A-M3/5B | Halogen-free variant; identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free compliance is mandated | Choose SMBG130A-M3/5B if RoHS + halogen-free material declaration is required for final product certification. |
| SMCJ130A-E3/5B | Higher 1500 W PPPM, larger SMC (DO-214AB) package, same VWM/VC ratings | Used where higher surge energy absorption is needed, e.g., primary front-end protection | Choose SMCJ130A-E3/5B when system-level surge testing exceeds 600 W or layout allows larger footprint. |
Compared with SMBG130A-E3/5B, the M3/5B variant offers identical protection performance with halogen-free construction, while SMCJ130A-E3/5B trades compactness for 2.5× higher pulse power - critical for front-end vs. point-of-load placement decisions.

FAQ
What is the clamping voltage of SMBG130A-E3/5B under a 10/1000 μs surge?
The SMBG130A-E3/5B has a maximum clamping voltage (VC) of 209 V at 2.9 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC standards. The SMBG130A-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG130A-E3/5B qualified for automotive applications?
Yes, SMBG130A-E3/5B is AEC-Q101 qualified, confirming its suitability for automotive electronic control units, body electronics, and powertrain subsystems. Qualification includes stress tests for temperature cycling, high-temperature reverse bias (HTRB), and surge endurance. The "HE3" and "HM3" base part number variants explicitly denote AEC-Q101 qualification, and the SMBG130A-E3/5B shares identical die and construction with those qualified versions per Vishay's ordering documentation.
What does the "E3/5B" suffix mean in SMBG130A-E3/5B?
The "E3" suffix indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads; "5B" specifies packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This differs from "52", which denotes 7-inch reels of 750 units. The E3/5B configuration supports high-volume SMT assembly with automated pick-and-place equipment and meets JESD 201 Class 2 whisker resistance requirements.
Can SMBG130A-E3/5B be used in bidirectional configurations?
No, SMBG130A-E3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBG130CA). Using SMBG130A-E3/5B in reverse-biased AC applications would result in forward conduction and failure. For symmetric transient protection on data lines like RS-485 or CAN, select the CA variant, which exhibits matched breakdown in both directions.
What is the thermal resistance of SMBG130A-E3/5B, and how does it affect layout?
The SMBG130A-E3/5B 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. This value assumes minimal copper area; increasing pad size or adding internal thermal vias reduces RθJA and lowers steady-state junction temperature. Layout must maintain ≥0.008" clearance from the cathode band to adjacent traces to avoid solder bridging and ensure reliable clamping performance in SMBG130A-E3/5B installations.
