Product details
Overview
SMBJ130A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising 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 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ130A-M3/52 datasheet, SMBJ130A-M3/52 pinout, SMBJ130A-M3/52 application, or SMBJ130A-M3/52 equivalent, key selection criteria include unidirectional polarity, 130 V stand-off rating, 209 V clamping performance under 2.9 A surge, thermal resistance of 100 °C/W (junction-to-ambient), and halogen-free RoHS-compliant construction per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with DC power rails or parallel to sensitive inputs. Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges, while its low incremental surge resistance ensures stable clamping during repetitive 10/1000 µs transients at 0.01% duty cycle.
The SMBJ130A-M3/52 is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and supports automated SMT placement via matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Confirmed minimum/maximum breakdown range ensuring predictable turn-on across production lots. |
| VC (Clamping Voltage) | 209 V at IPPM = 2.9 A - Measured peak voltage during 10/1000 µs surge; determines maximum stress imposed on protected circuitry. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 µs waveform; validates robustness against IEC 61000-4-5 surges. |
| IFSM (Surge Current) | 100 A - Peak forward surge rating for 8.3 ms half-sine wave; supports protection against inductive switch-off events in power stages. |
| TJmax | +150 °C - Maximum junction temperature; enables operation in high-ambient environments such as enclosed industrial enclosures. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements for sustained power dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant (M3 suffix), with cathode band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Provides path for surge current to ground when reverse-biased transient exceeds VWM; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; marked by band, connected to higher-potential side or VCC. | Defines polarity-sensitive placement - incorrect orientation disables clamping function and risks catastrophic failure under overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates compliance with IEC 61000-4-5 Level 3/4 surge immunity requirements for industrial equipment. |
| 209 V clamping voltage at 2.9 A | Limits voltage excursion across protected ICs to safe levels during transient events, preserving gate oxide integrity in MOSFETs. |
| 100 °C/W RθJA on standard pads | Enables thermal design without external heatsink in moderate-power applications (<5 W average dissipation). |
| Glass passivated junction | Ensures stable leakage current (<1 µA at VWM) and long-term reliability under humidity and temperature cycling. |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without popcorn cracking or delamination risk. |

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-E3/52 | Same electrical specs, but RoHS-compliant commercial grade with standard tin plating (not halogen-free). | No difference in surge protection function; differs only in material compliance and whisker resistance class. | Select E3/52 if halogen-free requirement is not mandated and cost optimization is prioritized. |
| SMCJ130A-M3 | Same VWM/VC, but in larger SMC (DO-214AB) package with 1500 W PPPM and lower RθJA (50 °C/W). | Higher surge handling capacity suits higher-energy threats (e.g., outdoor telecom), but requires larger PCB area. | Choose SMCJ130A-M3 when system-level surge testing exceeds 600 W or ambient temperature exceeds 85 °C. |

FAQ
What is the clamping voltage of SMBJ130A-M3/52 at its rated peak pulse current?
The SMBJ130A-M3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its specified peak pulse current of 2.9 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ130A-M3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ130A-M3/52 suitable for automotive applications requiring AEC-Q101 qualification?
No - SMBJ130A-M3/52 is a commercial-grade, halogen-free, RoHS-compliant part but is not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ130AHM3_X variant (e.g., SMBJ130AHM3_A), which carries the HM3 suffix and explicit AEC-Q101 qualification. The SMBJ130A-M3/52 lacks the extended temperature cycling, humidity testing, and failure rate validation required for automotive ECUs or body control modules.
How does the M3 suffix differ from E3 in SMBJ130A-M3/52 versus SMBJ130A-E3/52?
The M3 suffix indicates halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while E3 denotes standard RoHS compliance without halogen-free assurance. Both share identical electrical parameters, package (SMB), and thermal ratings. The SMBJ130A-M3/52 is specified for applications requiring strict halogen content limits (e.g., EU public infrastructure projects), whereas SMBJ130A-E3/52 meets baseline RoHS but may contain brominated flame retardants in molding compound.
What is the maximum reverse leakage current of SMBJ130A-M3/52 at its standoff voltage?
The SMBJ130A-M3/52 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 130 V standoff voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensor interfaces. Leakage remains below 5 µA up to +125 °C, as confirmed by Vishay's thermal derating curves.
Can SMBJ130A-M3/52 be used in bidirectional protection configurations?
No - SMBJ130A-M3/52 is strictly unidirectional, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ130CA). Using SMBJ130A-M3/52 in reverse-biased configurations outside its specified polarity will result in premature breakdown and potential failure. For symmetrical AC line protection, select SMBJ130CA-M3/52 instead.
