Product details
Overview
SMBJ130D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V stand-off voltage (VWM), 146–157 V breakdown voltage (VBR) at 1 mA, 206 V maximum clamping voltage (VC) at 2.94 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ130D-M3/I datasheet, SMBJ130D-M3/I pinout, SMBJ130D-M3/I application, or SMBJ130D-M3/I equivalent, key selection criteria include clamping performance under 2.94 A surge, thermal resistance (RθJA = 125 °C/W on minimum pad), unidirectional polarity marking, and industrial-grade M3 suffix compliance (halogen-free, RoHS, JESD 201 Class 2 whisker test).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its VBR threshold to divert transient energy away from downstream circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events without latch-up or degradation under repetitive 0.01 % duty cycle surges.
The device is rated for -55 °C to +150 °C junction temperature, with power dissipation derated above 25 °C ambient (1.0 W at TA = 25 °C; 5.0 W at TM = 50 °C on infinite heatsink). It meets UL 497B recognition (QVGQ2) and MSL Level 1 per J-STD-020 (peak reflow 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 146 V / 157 V at 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 206 V at 2.94 A - Clamping voltage limits stress on protected ICs during 10/1000 μs transients |

| ID @ VWM | 0.5 μA - Ultra-low leakage preserves efficiency in high-impedance bias networks |
| RθJA | 125 °C/W - Thermal resistance on minimum recommended PCB pad layout dictates derating requirements |

Applications
| Industrial Motor Drive Power Rails | Telecom Line Card DC Inputs |
|---|---|
Use Scenario: Protection of 120–150 V DC bus against inductive kickback from contactor switching and relay coil de-energization.

IC Role / Device Role / Timing Role: Low-leakage (0.5 μA) clamp on signal return path, referenced to local ground plane. Use Value: Avoids baseline shift or ADC offset errors caused by leakage current in precision 24-bit sigma-delta converters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-M3/I | Bidirectional variant; symmetric VBR/VWM (146–157 V) in both directions; no polarity marking | Required where AC-coupled lines or bidirectional data buses (e.g., RS-485) need symmetrical clamping | Select SMBJ130A-M3/I only if protection must function identically for positive and negative transients; SMBJ130D-M3/I is optimal for DC rails with defined polarity. |
| SMCJ130A-M3/I | Larger SMC (DO-214AB) package; higher 1500 W PPPM; RθJA = 40 °C/W (on same pad); same VWM/VBR range | Suitable for higher-energy surge environments (e.g., outdoor power supplies) where board space allows larger footprint | Choose SMCJ130A-M3/I when 1500 W surge rating is mandatory and thermal budget permits larger package; SMBJ130D-M3/I fits tighter layouts with adequate 600 W rating. |
Compared with SMBJ130A-M3/I and SMCJ130A-M3/I, the SMBJ130D-M3/I offers optimized space efficiency and unidirectional clamping for fixed-polarity DC systems, while maintaining identical voltage ratings and industrial M3 reliability-making it ideal for compact, cost-sensitive industrial and telecom power protection.

FAQ
What is the clamping voltage of SMBJ130D-M3/I and how is it measured?
The SMBJ130D-M3/I has a maximum clamping voltage (VC) of 206 V, measured at a peak pulse current (IPPM) of 2.94 A using a 10/1000 μs double-exponential surge waveform. This value represents the upper voltage limit imposed on the protected circuit during standardized transient events and is guaranteed across the full operating temperature range per Vishay Document 87606.
Does SMBJ130D-M3/I meet UL recognition requirements?
Yes, SMBJ130D-M3/I is Underwriters Laboratories (UL) recognized under standard UL 497B (file E136766) for both unidirectional and bidirectional variants. This certification confirms its suitability as a primary protector in telecommunications and industrial equipment subject to regulatory safety audits.
What does the "M3" suffix indicate in SMBJ130D-M3/I?
"M3" denotes Vishay's industrial-grade qualification: halogen-free molding compound, RoHS compliance, and passing JESD 201 Class 2 whisker testing. It also specifies matte tin-plated leads compatible with J-STD-002 solderability standards-critical for high-reliability manufacturing environments.
Can SMBJ130D-M3/I be used in bidirectional signal protection?
No-SMBJ130D-M3/I is unidirectional and functions only in reverse-bias clamping mode. For bidirectional protection (e.g., AC lines or differential buses), the SMBJ130A-M3/I variant must be selected, as it provides symmetrical clamping characteristics in both polarities.
What is the thermal resistance of SMBJ130D-M3/I and how does it affect layout design?
SMBJ130D-M3/I has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended PCB pad layout. This requires careful copper area allocation-Vishay specifies a 5.0 mm × 5.0 mm copper pad to achieve lower RθJA (100 °C/W)-to avoid exceeding the 150 °C max junction temperature under sustained power dissipation.
