Product details
Overview
SMBG130A-M3/5B 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 - used in automotive power supply input stages and industrial sensor interfaces.
For engineers reviewing the SMBG130A-M3/5B datasheet, SMBG130A-M3/5B pinout, SMBG130A-M3/5B application, or SMBG130A-M3/5B equivalent, key selection criteria include clamping performance under repetitive surge conditions, AEC-Q101 qualification for automotive use, halogen-free RoHS compliance (M3 suffix), and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a unidirectional shunt protector, conducting only during reverse-biased overvoltage events above its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), while the low incremental surge resistance enables effective energy diversion without thermal runaway.
The device is rated for -55 °C to +150 °C operating junction temperature, supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for high-reliability surface-mount assembly in automotive ECUs and industrial PLC I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V/24 V/48 V systems. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Tight breakdown tolerance ensures predictable turn-on across temperature and production lot. |
| VC @ IPPM | 209 V at 2.9 A - Clamping voltage limits downstream IC stress during 10/1000 μs transients per ISO 7637-2 Pulse 5a. |
| PPPM | 600 W - Peak pulse power handling capability with 0.01 % duty cycle; validated on 5.0 mm × 5.0 mm copper pads. |
| IFSM | 100 A - Surge current rating for 8.3 ms half-sine wave; supports load-dump immunity in automotive 12 V systems. |
| TJ max | +150 °C - Enables operation in under-hood environments and sealed industrial enclosures without derating. |
| RθJA | 100 °C/W - Thermal resistance informs board-level thermal design; requires minimum pad area per datasheet fig. 2. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, gull-wing lead form, matte tin-plated terminals solderable per J-STD-002. Cathode indicated by band marking; anode is unmarked end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG130A-E3/5B | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3). | Not qualified to AEC-Q101; unsuitable for automotive under-hood use. | Select SMBG130A-M3/5B when halogen-free and automotive qualification are required. |
| SMBJ130A-M3/5B | Same VWM/VC, but SMBJ package (DO-214AB) has higher RθJA (125 °C/W) and lower IPPM (2.5 A). | Lower power handling; suited for space-constrained consumer PCBs, not high-energy automotive transients. | Choose SMBG130A-M3/5B for superior thermal performance and 600 W rating in industrial/automotive designs. |
Compared with SMBG130A-E3/5B and SMBJ130A-M3/5B, the SMBG130A-M3/5B uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized thermal resistance (100 °C/W) - making it the preferred choice for automotive-grade 130 V rail protection where long-term reliability under thermal cycling is critical.

FAQ
What is the clamping voltage of SMBG130A-M3/5B at its rated peak pulse current?
The SMBG130A-M3/5B has a maximum clamping voltage (VC) of 209 V at its rated peak pulse current of 2.9 A (10/1000 μs waveform). This value is measured under standardized test conditions with 5.0 mm × 5.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG130A-M3/5B maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBG130A-M3/5B suitable for automotive applications?
Yes, SMBG130A-M3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its construction includes halogen-free, RoHS-compliant materials (M3 suffix), MSL Level 1 moisture sensitivity, and thermal stability up to +150 °C junction temperature. The SMBG130A-M3/5B meets ISO 7637-2 load dump immunity requirements when applied per Vishay's recommended PCB layout and thermal design guidelines.
How does the SMBG130A-M3/5B differ from the SMBG130CA-M3/5B?
The SMBG130A-M3/5B is unidirectional, while SMBG130CA-M3/5B is bidirectional - meaning the latter protects against transients of either polarity and has no cathode marking. Electrically, both share identical VWM (130 V), VBR (144–159 V), and VC (209 V) ratings, but the unidirectional SMBG130A-M3/5B supports forward surge current (IFSM = 100 A), whereas the bidirectional version does not specify IFSM. The SMBG130A-M3/5B is selected for DC rail protection; SMBG130CA-M3/5B suits AC or differential signal lines.
What is the maximum reverse leakage current for SMBG130A-M3/5B at its stand-off voltage?
The SMBG130A-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM = 130 V) and ambient temperature of 25 °C. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. Leakage remains within specification across the full operating temperature range, verified per Vishay's electrical characterization methodology in Document Number 88456.
Does SMBG130A-M3/5B require special PCB layout considerations?
Yes - optimal performance of SMBG130A-M3/5B requires adherence to Vishay's recommended mounting pad layout: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, with minimum trace width and direct connection to internal ground planes. Deviation increases thermal resistance (RθJA) beyond the rated 100 °C/W and may elevate clamping voltage during high-current surges. The SMBG130A-M3/5B datasheet (88456, Rev. 09-Jan-2024) provides exact dimensions and thermal derating curves.
