Product details
Overview
SMBJ130CA-M3/52 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 stand-off voltage (VWM), 209 A peak pulse current (IPPM) under 10/1000 µs waveform, 209 V maximum clamping voltage (VC), and 600 W peak pulse power rating - deployed to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives and telecom power supplies.
For engineers reviewing the SMBJ130CA-M3/52 datasheet, SMBJ130CA-M3/52 pinout, SMBJ130CA-M3/52 application, or SMBJ130CA-M3/52 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, JEDEC-compliant SMB package dimensions, and AEC-Q101-qualified alternatives for automotive-grade surge protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 144–159 V (min/max) at 1 mA test current, and clamps to ≤209 V at 209 A surge. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients like EFT or lightning-induced surges.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Confirmed bidirectional avalanche threshold; ensures symmetrical overvoltage protection. |
| VC (Clamping Voltage) | ≤209 V at IPPM = 209 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 µs waveform; validates robustness against IEC 61000-4-5 surges. |
| IPPM (Peak Pulse Current) | 209 A - Maximum non-repetitive surge current handled without degradation; derived directly from VC and PPPM. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in high-ambient environments such as enclosed industrial enclosures or under-hood automotive modules. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical anode/cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity required in layout. |
| Terminal 2 | Anode / Cathode (bidirectional) | Paired terminal completing symmetrical clamping path; enables placement across differential or single-ended lines without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validated surge handling for IEC 61000-4-5 Level 4 (4 kV line-to-line) in properly decoupled systems. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs - e.g., keeps microcontroller I/O pins below absolute maximum ratings during surge events. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and EU Directive 2015/863 for restricted substances. |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free assembly without moisture sensitivity concerns or baking preconditioning. |
| 150 °C maximum junction temperature | Supports operation in sealed enclosures with ambient temperatures up to +105 °C when mounted on 5.0 mm × 5.0 mm copper pads. |

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_B/H | AEC-Q101 qualified; identical VWM, VBR, VC, and PPPM; same SMB package; RoHS-compliant but not halogen-free. | Required for automotive production where qualification to AEC-Q101 is mandatory (e.g., under-hood modules). | Select when automotive qualification is needed; otherwise SMBJ130CA-M3/52 offers halogen-free compliance for industrial green initiatives. |
| SMCJ130CA-M3 | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; 1500 W PPPM; higher IPPM (338 A). | Suitable where higher surge margin is required (e.g., outdoor telecom cabinets) and PCB space allows larger footprint. | Choose for enhanced surge headroom; SMBJ130CA-M3/52 remains optimal where space-constrained layouts demand SMB size. |
Compared with SMBJ130CAHE3_B/H, the SMBJ130CA-M3/52 trades AEC-Q101 qualification for halogen-free compliance - ideal for industrial and telecom applications prioritizing environmental standards. Against SMCJ130CA-M3, it delivers identical clamping performance in 40% smaller area, enabling denser board layouts without sacrificing 600 W surge capability.

FAQ
What is the maximum clamping voltage of SMBJ130CA-M3/52 at its rated peak pulse current?
The SMBJ130CA-M3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 209 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88392. The SMBJ130CA-M3/52 maintains this clamping performance bidirectionally, making it suitable for protecting balanced and unbalanced signal paths alike.
Is SMBJ130CA-M3/52 suitable for automotive applications?
The SMBJ130CA-M3/52 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive applications requiring formal qualification (e.g., engine control units or ADAS modules), Vishay offers the pin-compatible SMBJ130CAHE3_B/H variant. However, the SMBJ130CA-M3/52 remains appropriate for non-safety-critical automotive subsystems such as infotainment power rails or lighting control where qualification is not mandated - provided system-level testing validates its surge performance under ISO 7637-2 conditions. Always verify final design compliance using the SMBJ130CA-M3/52 datasheet.
How does the SMBJ130CA-M3/52 differ from unidirectional SMBJ130A-M3/52?
The SMBJ130CA-M3/52 is bidirectional, meaning it clamps voltage transients equally in both polarities - essential for protecting AC lines, differential buses (e.g., RS-485, CAN), or floating nodes. In contrast, the unidirectional SMBJ130A-M3/52 has a cathode band marking and only clamps in reverse bias; forward conduction follows standard diode behavior. Their VWM, VBR, and VC values differ accordingly: SMBJ130CA-M3/52 specifies VWM = 130 V (bidirectional), while SMBJ130A-M3/52 specifies VWM = 130 V (reverse only). Layout and circuit function must align with this fundamental polarity distinction.
What is the thermal resistance of SMBJ130CA-M3/52, and how does it affect PCB layout?
The SMBJ130CA-M3/52 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 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under full 600 W surge duty, PCB layout must provide adequate copper area and minimize trace length to thermal planes. Reducing pad size or omitting thermal vias increases RθJA, risking thermal runaway during repetitive surges. The SMBJ130CA-M3/52 datasheet Fig. 2 provides derating curves for elevated ambient temperatures.
Does SMBJ130CA-M3/52 require orientation during PCB placement?
No - the SMBJ130CA-M3/52 is a bidirectional TVS diode with no polarity marking on the SMB (DO-214AA) package. Both terminals are functionally identical, allowing unrestricted placement on PCBs without regard to anode/cathode orientation. This simplifies automated assembly and eliminates risk of reverse installation errors common with unidirectional variants (e.g., SMBJ130A-M3/52, which features a cathode band). The SMBJ130CA-M3/52 achieves symmetrical clamping by internal back-to-back diode construction, verified in Vishay's electrical characteristics table.
