Product details
Overview
SMBJ130CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 A peak pulse current (IPPM) with 10/1000 µs waveform, and 600 W peak pulse power dissipation - deployed to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom infrastructure.
For engineers reviewing the SMBJ130CAHM3_A/I datasheet, SMBJ130CAHM3_A/I pinout, SMBJ130CAHM3_A/I application, or SMBJ130CAHM3_A/I equivalent, this device serves as a halogen-free, RoHS-compliant, AEC-Q101 qualified TVS for high-reliability transient suppression where bidirectional clamping, low clamping voltage (209 V), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its silicon avalanche junction delivers sub-nanosecond response time and low dynamic impedance (<0.5 Ω typical surge resistance), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device is rated for continuous operation from –55 °C to +150 °C junction temperature and exhibits a VBR temperature coefficient of +0.108 %/°C. Thermal resistance is 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and 20 °C/W (junction-to-lead), supporting robust thermal performance in compact PCB layouts.

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_A/I | Same electrical specs and SMB package; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification. | Suitable for commercial/industrial use only; not approved for automotive under hood or chassis locations. | Select when halogen-free content is not mandated and automotive qualification is unnecessary. |
| SMCJ130CAHM3_A/I | Same VWM, VBR, and bidirectional function; larger SMC (DO-214AB) package with 1500 W PPPM. | Requires larger PCB area; used where higher surge margin (e.g., outdoor telecom cabinets) justifies footprint increase. | Choose when system-level surge testing exceeds 600 W requirements and layout space permits SMC footprint. |
Compared with SMBJ130CAHM3_A/I, the HE3 variant trades halogen-free construction and automotive qualification for lower cost in non-automotive settings, while the SMCJ130CAHM3_A/I offers 2.5× higher surge power in a larger package - making SMBJ130CAHM3_A/I optimal for space-constrained, AEC-Q101–required designs needing precise 600 W capability.

FAQ
What is the clamping voltage of SMBJ130CAHM3_A/I at its rated peak pulse current?
The SMBJ130CAHM3_A/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated 209 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMBJ130CAHM3_A/I maintains this clamping performance across its full operating temperature range.
Is SMBJ130CAHM3_A/I suitable for automotive applications?
Yes - the HM3 suffix confirms that SMBJ130CAHM3_A/I is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D. The SMBJ130CAHM3_A/I is approved for use in automotive body electronics, infotainment power rails, and LIN/CAN interface protection where bidirectional surge suppression is required.
How does the bidirectional design of SMBJ130CAHM3_A/I affect its circuit placement?
The SMBJ130CAHM3_A/I has no polarity marking and functions identically in both directions, allowing placement across AC-coupled lines, floating sensor outputs, or differential bus pairs without orientation constraints. Unlike unidirectional TVS diodes, it eliminates risk of incorrect installation and simplifies layout for symmetric protection schemes - such as across RS-485 lines or dual-rail sensor outputs - where voltage transients may occur with either polarity.
What is the thermal resistance of SMBJ130CAHM3_A/I under standard mounting conditions?
Under standard JEDEC test conditions (mounted on 0.2" × 0.2" copper pads per terminal), the SMBJ130CAHM3_A/I exhibits a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a junction-to-lead resistance (RθJL) of 20 °C/W. These values enable reliable operation at full 5.0 W steady-state power dissipation up to +50 °C ambient, provided minimum pad layout guidelines from the Vishay datasheet are followed.
Does SMBJ130CAHM3_A/I meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes - SMBJ130CAHM3_A/I is rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This allows indefinite floor life and direct placement into standard lead-free reflow profiles without pre-baking. The device's matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, ensuring robust wetting and joint integrity in high-volume SMT assembly.
