Product details
Overview
SMBJ130AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. 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 a 10/1000 µs waveform.
For engineers reviewing the SMBJ130AHM3_B/I datasheet, SMBJ130AHM3_B/I pinout, SMBJ130AHM3_B/I application, or SMBJ130AHM3_B/I equivalent, this device is selected for robust overvoltage protection in automotive power rails, industrial sensor interfaces, and telecom line-level circuits where fast response (<1 ps), low incremental surge resistance, and AEC-Q101 qualification are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche behavior under repetitive surge conditions. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (–55 °C to +150 °C) support operation in high-ambient environments when mounted on standard 5.0 mm × 5.0 mm copper pads.
The SMBJ130AHM3_B/I delivers precise voltage limiting with a 0.108 %/°C temperature coefficient of VBR, enabling predictable clamping across temperature. Its 1.0 µA maximum reverse leakage at VWM ensures minimal standby power loss in always-on systems such as automotive body control modules and industrial PLC I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Guaranteed avalanche initiation range; ensures reliable turn-on during transients without premature triggering. |
| VC (Clamping Voltage) | 209 V at 2.9 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines downstream component voltage stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized surge waveform; validates suitability for IEC 61000-4-5 Level 4 compliance. |
| IPPM (Peak Pulse Current) | 2.9 A - Maximum non-repetitive surge current it can divert without degradation; sets minimum series impedance requirements for protection networks. |
| TJmax | +150 °C - Maximum junction temperature; enables use in under-hood automotive locations and industrial enclosures without derating. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.205" × 0.130" footprint; compatible with automated pick-and-place and reflow soldering per J-STD-020 MSL level 1. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, halogen-free and RoHS-compliant (HM3 suffix). Polarity indicated by cathode band on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; completes clamping loop during transient events. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail, RS-485 bus); carries full surge current into ground via anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power domains, supporting long-term reliability under thermal cycling and vibration. |

| Low clamping ratio (VC/VWM ≈ 1.61) | Minimizes overvoltage exposure to downstream ICs-critical for safeguarding 130 V-rated capacitors and MOSFETs in DC-DC converters. |
| 0.108 %/°C VBR tempco | Ensures stable clamping threshold across –40 °C to +125 °C ambient, reducing design margin uncertainty in wide-temperature deployments. |
| MSL level 1 (260 °C peak) | Permits single-reflow assembly without moisture sensitivity concerns, eliminating bake-out steps and supporting high-yield manufacturing. |
Applications

| Telecom Line-Level Surge Suppression | DC-DC Converter Input Protection |
|
Use Scenario: Safeguarding PoE-powered Ethernet ports and base station RF front-end bias lines against lightning-induced surges. IC Role / Device Role / Timing Role: Primary clamping device on DC bias feed lines (e.g., +48 V phantom power), coordinated with GDT or MOV secondary protection. Use Value: Absorbs 600 W surge energy while maintaining <209 V clamping, allowing upstream fusing to remain intact and avoiding service interruption. |
Use Scenario: Securing input stage of isolated 48 V-to-12 V DC-DC converters used in server power supplies and industrial HMIs. IC Role / Device Role / Timing Role: Fast-acting unidirectional suppressor placed directly at converter input capacitor to prevent overvoltage failure during hot-swap events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130AHE3_B/I | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification; same electrical specs and SMB package. | Approved for commercial/industrial use only-not certified for automotive under-hood deployment. | Select when AEC-Q101 is not required and cost optimization is prioritized over halogen-free compliance. |
| SMBJ130A-M3/5B | Same halogen-free and RoHS compliance; packaged in 13" tape (3200 pcs/reel); identical VWM, VBR, and PPPM. | Intended for high-volume production with bulk reel delivery; no functional difference in circuit performance. | Choose for large-scale manufacturing runs requiring extended reel length and optimized logistics handling. |
Compared with SMBJ130AHM3_B/I, the HE3 variant trades halogen-free construction and automotive qualification for lower unit cost, while the M3/5B variant offers identical performance in a higher-density packaging format-enabling selection based on compliance needs and production scale rather than electrical redesign.

FAQ
What is the maximum clamping voltage of SMBJ130AHM3_B/I under a 10/1000 µs surge?
The SMBJ130AHM3_B/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 2.9 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 and Table 1 in Vishay's Document Number 88392 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ130AHM3_B/I maintains this clamping performance across its full operating temperature range.
Is SMBJ130AHM3_B/I qualified for automotive applications?
Yes, SMBJ130AHM3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HM3" suffix denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified variants) and documented in the "MECHANICAL DATA" section of the datasheet. This qualification covers stress testing for temperature cycling, mechanical shock, and humidity resistance-making SMBJ130AHM3_B/I suitable for under-hood and chassis-mounted automotive electronics.
What does the "HM3" suffix indicate in SMBJ130AHM3_B/I?
The "HM3" suffix in SMBJ130AHM3_B/I specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, HM3 denotes compliance with JEDEC JESD201 Class 2 whisker resistance, matte tin plating, and UL 94 V-0 molding compound-distinguishing it from E3 (RoHS only) and HE3 (RoHS + AEC-Q101, but not halogen-free) variants. The SMBJ130AHM3_B/I meets all three criteria.
Can SMBJ130AHM3_B/I be used in bidirectional protection circuits?
No, SMBJ130AHM3_B/I is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBJ130CA). Using SMBJ130AHM3_B/I in AC-coupled or symmetrical surge environments would result in forward conduction during negative half-cycles, potentially causing failure. For bidirectional protection, select SMBJ130CA or equivalent.
What is the thermal resistance from junction to ambient for SMBJ130AHM3_B/I?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ130AHM3_B/I is 100 °C/W, measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the "THERMAL CHARACTERISTICS" table. This value guides PCB layout decisions-larger copper areas or internal planes reduce effective RθJA, improving surge survivability during repetitive events. The SMBJ130AHM3_B/I's RθJA supports operation up to +150 °C junction temperature.
