Product details
Overview
SMBJ130A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), and clamps transients to ≤209 V at 2.9 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed in power supply rails, I/O interfaces, and sensor signal lines across industrial and telecom systems.
For engineers reviewing the SMBJ130A-M3/5B datasheet, SMBJ130A-M3/5B pinout, SMBJ130A-M3/5B application, or SMBJ130A-M3/5B equivalent, key selection criteria include its 600 W peak pulse power rating, 1.0 µA max reverse leakage at VWM, halogen-free RoHS-compliant SMB (DO-214AA) package, and AEC-Q101 qualification readiness via HM3 suffix variants.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), with maximum junction temperature rated at +150 °C. The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and meets MSL Level 1 per J-STD-020 (peak reflow 260 °C).

FAQ
What is the maximum clamping voltage of the SMBJ130A-M3/5B under standard test conditions?
The SMBJ130A-M3/5B has a maximum clamping voltage (VC) of 209 V when subjected to a 10/1000 µs waveform at a peak pulse current (IPPM) of 2.9 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ130A-M3/5B maintains this clamping performance across its qualified operating temperature range.
Is the SMBJ130A-M3/5B suitable for automotive applications?
The SMBJ130A-M3/5B itself is a commercial-grade, halogen-free, RoHS-compliant part and is not AEC-Q101 qualified. However, Vishay offers the functionally identical SMBJ130AHM3_B/I variant - same electrical specs and SMB package - which is fully AEC-Q101 qualified. For automotive use, specify the HM3 suffix version; the SMBJ130A-M3/5B remains appropriate for industrial and telecom applications where automotive qualification is not required.
What does the "M3" suffix indicate in SMBJ130A-M3/5B?
The "M3" suffix in SMBJ130A-M3/5B denotes halogen-free, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards. It also satisfies JESD 201 Class 2 whisker resistance testing. This distinguishes it from the "E3" suffix (RoHS-compliant but not halogen-free) and "HM3" suffix (halogen-free + AEC-Q101 qualified). The SMBJ130A-M3/5B is intended for commercial and industrial applications requiring environmentally compliant components.
How does the SMBJ130A-M3/5B compare to bidirectional TVS diodes like SMBJ130CA?
The SMBJ130A-M3/5B is unidirectional and designed for DC line protection where polarity is fixed (e.g., positive supply rails), offering lower leakage and tighter VBR tolerance than bidirectional equivalents. In contrast, SMBJ130CA provides symmetrical clamping for AC or floating signal lines but exhibits higher reverse leakage and wider VBR spread. The SMBJ130A-M3/5B should not be substituted for SMBJ130CA without verifying circuit polarity and surge directionality - using it in bidirectional applications risks failure during negative transients.
What is the thermal resistance and maximum junction temperature rating for the SMBJ130A-M3/5B?
The SMBJ130A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on standard 5.0 mm × 5.0 mm copper pads. Its maximum operating and storage junction temperature is rated from –55 °C to +150 °C. These values define safe power derating curves above 25 °C ambient and ensure reliable operation in enclosed industrial enclosures or under sustained surge duty cycles - critical for validating thermal design margins in the SMBJ130A-M3/5B application.
