Product details
Overview
SMBJ130CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), clamping voltage of 209 V at 2.9 A, and operates across –55 °C to +150 °C junction temperature range - deployed in industrial sensor signal lines and telecom interface protection.
For engineers reviewing the SMBJ130CAHM3/I datasheet, SMBJ130CAHM3/I pinout, SMBJ130CAHM3/I application, or SMBJ130CAHM3/I equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and real-world use cases in automotive-grade power rail and data line surge suppression.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its symmetrical I-V characteristic ensures identical clamping in both polarities, with no polarity marking required on the SMB package.
The device is rated for 600 W peak pulse power under standard 10/1000 μs waveform, derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surge duty cycle ≤0.01%. It meets MSL Level 1 per J-STD-020 and is halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002.
Key Specifications

|---|---|
|
Use Scenario: Protecting 4–20 mA current-loop sensors in factory automation against inductive kickback and EFT bursts. IC Role / Device Role / Timing Role: Bidirectional TVS placed across sensor input terminals to clamp transients before they reach precision ADC or op-amp front-end. Use Value: Prevents latch-up or damage to analog signal conditioning ICs by limiting voltage to ≤209 V during 2.9 A surges - preserving measurement integrity and system uptime. |
Use Scenario: Safeguarding LIN bus transceivers and microcontroller GPIOs in door module ECUs exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected between LIN line and ground, absorbing energy from 100 V/50 ms load dump events. Use Value: Maintains communication continuity by clamping without conduction at 130 V nominal, then activating within nanoseconds to hold line voltage below 209 V. |
| Telecom Interface Protection | Power Supply Input Stage |
|
Use Scenario: Shielding RS-485 transceivers in base station remote units from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Bidirectional TVS placed differential-mode across A/B lines and common-mode to ground, forming first-line defense in multi-stage protection. Use Value: Delivers 600 W surge capacity with <1 ns response - faster than MOVs or GDTs - ensuring semiconductor-level protection before secondary clamping stages activate. |
Use Scenario: Secondary overvoltage protection on 12 V DC input rails of embedded gateways after primary DC-DC converter filtering. IC Role / Device Role / Timing Role: Standby TVS shunting transient energy to ground during input voltage spikes caused by hot-plug or back-EMF from connected peripherals. Use Value: Withstands repeated 10/1000 μs surges up to 2.9 A while leaking only 1.0 μA at 130 V - minimizing standby power loss and thermal stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CAHE3/I | Same electrical specs and SMB package; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification | Suitable for commercial-grade industrial equipment where automotive reliability is not required | Select when cost sensitivity outweighs halogen-free or automotive qualification needs |
| SMAJ130CAHM3/I | Lower 400 W PPPM rating; same VWM/VBR/VC; SMA (DO-214AC) package with smaller footprint and higher RθJA (140 °C/W) | Better suited for space-constrained consumer devices with lower surge immunity requirements | Choose only if board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
Compared with SMBJ130CAHM3/I, the HE3 variant trades halogen-free construction and AEC-Q101 validation for lower cost, while the SMAJ version sacrifices 33% pulse power headroom and thermal performance for compactness - making SMBJ130CAHM3/I optimal for automotive and industrial designs demanding full 600 W surge resilience.

FAQ
What does the "CA" suffix indicate in SMBJ130CAHM3/I?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ130CAHM3/I provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBJ130A), it has no cathode band marking and exhibits identical VBR, VC, and clamping behavior in either polarity, making it ideal for AC signal lines, differential buses like RS-485, and floating power domains where polarity reversal may occur.
Is SMBJ130CAHM3/I qualified for automotive applications?
Yes, SMBJ130CAHM3/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HM3" suffix with "_X" revision indicator). This qualification validates its robustness under automotive temperature cycling, humidity, mechanical shock, and lifetime reliability testing - enabling use in body control modules, infotainment power supplies, and ADAS sensor interfaces where failure modes must be rigorously controlled.
How does the SMB package of SMBJ130CAHM3/I compare thermally to SMA or SMC packages?
SMBJ130CAHM3/I in the SMB (DO-214AA) package offers RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads - significantly better than SMA (RθJA ≈ 140 °C/W) but less efficient than SMC (RθJA ≈ 60 °C/W). This balance makes SMBJ130CAHM3/I suitable for medium-power surge events where board space is constrained but thermal dissipation must exceed SMA limits, especially in multi-pulse or high-ambient environments.
What is the maximum clamping voltage of SMBJ130CAHM3/I under surge conditions?
The maximum clamping voltage (VC) of SMBJ130CAHM3/I is 209 V at a peak pulse current (IPPM) of 2.9 A, measured using the standardized 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case surge events, directly determining whether downstream components like microcontrollers or transceivers remain within their absolute maximum ratings.
Can SMBJ130CAHM3/I replace SMBJ130A in an existing design?
No - SMBJ130CAHM3/I is bidirectional, while SMBJ130A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: SMBJ130CAHM3/I works only where symmetrical clamping is needed (e.g., AC-coupled lines), whereas SMBJ130A is required for DC-biased rails where forward conduction must be blocked. Using SMBJ130CAHM3/I in place of SMBJ130A may cause unintended conduction in DC paths, risking malfunction or damage.
