Product details
Overview
SMBJ130CA-M3/5B 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), 600 W peak pulse power (10/1000 µs), 2.9 A peak pulse current (IPPM), and clamps to ≤209 V at rated surge. It protects MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ130CA-M3/5B datasheet, SMBJ130CA-M3/5B pinout, SMBJ130CA-M3/5B application, or SMBJ130CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, 130 V working voltage compatibility, 209 V max clamping voltage under 2.9 A surge, MSL Level 1 reflow rating, and halogen-free RoHS compliance per Vishay's M3 suffix.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its silicon avalanche junction provides sub-nanosecond response time and low dynamic impedance during transient events, enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2 in the datasheet. Thermal resistance is 100 °C/W junction-to-ambient (RθJA) on standard 0.2" × 0.2" copper pads, supporting reliable operation in compact, convection-cooled PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | ≤209 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during full-rated 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs waveform) - Surge energy handling capacity; supports IEC 61000-4-5 Level 3/4 compliance when properly laid out. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - Negligible standby power loss and minimal impact on high-impedance signal lines. |
| TJ max. | 150 °C - Enables use in high-temperature environments such as enclosed industrial enclosures or near power converters. |

Applications
| Industrial Power Supply Input Protection | Telecom Line Card Surge Protection |
|---|---|
Use Scenario: AC/DC and DC/DC power supplies exposed to load dump, hot-swap transients, and back EMF from relays or solenoids. IC Role / Device Role / Timing Role: Primary clamping element placed across input bus or between rail and ground to limit transient voltage excursions. Use Value: Limits input surge to ≤209 V, preventing damage to upstream rectifiers, PFC controllers, and primary-side MOSFETs rated for 250 V or less. |
Use Scenario: Protection of Ethernet PHY interfaces, xDSL line drivers, and analog front-end circuits in central office and CPE equipment. IC Role / Device Role / Timing Role: Bidirectional shunt clamp on differential pairs or single-ended signal lines subject to lightning-induced common-mode surges. Use Value: Symmetric clamping ensures equal protection regardless of surge polarity - essential for balanced telecom signaling standards. |
| Automotive Body Control Module (BCM) Inputs | Sensor Signal Line Protection |
Use Scenario: 12 V battery-fed inputs (e.g., ignition sense, door switch, LIN bus) subjected to ISO 7637-2 pulses 1, 2a, 3a/b, and 5a. IC Role / Device Role / Timing Role: Secondary-level transient suppressor downstream of fuse or polyfuse, co-located with connector entry points. Use Value: Withstands repetitive 100 V/500 ms pulses while maintaining <1 µA leakage - preserves low-power sleep mode integrity in BCM microcontrollers. |
Use Scenario: Analog sensor outputs (e.g., pressure, temperature, position) routed through long harnesses susceptible to ESD and coupled noise. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF at 0 V) shunt clamp placed directly at sensor IC output pin or connector interface. Use Value: Sub-nanosecond response prevents transient coupling into ADC reference paths - maintains ±0.5% measurement accuracy under 8 kV contact ESD. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-E3/5B | Same electrical specs; RoHS-compliant but contains brominated flame retardants (not halogen-free). | Acceptable where halogen-free requirement is not enforced (e.g., non-EU commercial equipment). | Select SMBJ130CA-E3/5B only if halogen content is unrestricted and cost is prioritized over green compliance. |
| SMCJ130CA-M3 | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; 1500 W PPPM rating. | Used where higher surge margin is needed (e.g., outdoor telecom cabinets), but requires 30% more board area. | Choose SMCJ130CA-M3 only when 1500 W surge headroom is required and PCB space permits larger footprint. |
Compared with SMBJ130CA-E3/5B, the SMBJ130CA-M3/5B offers halogen-free construction without sacrificing electrical performance; versus SMCJ130CA-M3, it trades 2.5× lower surge rating for 30% smaller PCB area and compatibility with dense SMT layouts.

FAQ
What is the clamping voltage of SMBJ130CA-M3/5B at its rated peak pulse current?
The SMBJ130CA-M3/5B clamps to a maximum of 209 V when subjected to its rated peak pulse current of 2.9 A (10/1000 µs waveform). This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88392) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is SMBJ130CA-M3/5B suitable for automotive applications?
SMBJ130CA-M3/5B is not AEC-Q101 qualified; it carries the M3 commercial-grade suffix. For automotive use, Vishay specifies the HM3 suffix (e.g., SMBJ130CAHM3_B/I), which adds AEC-Q101 qualification. The SMBJ130CA-M3/5B is appropriate for industrial and telecom applications but not for automotive safety-critical or qualified subsystems.
Does SMBJ130CA-M3/5B have polarity markings on the package?
No - SMBJ130CA-M3/5B is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMB (DO-214AA) package body. Its symmetrical construction means either terminal functions identically under positive or negative transients, simplifying PCB layout and assembly.
What is the thermal resistance of SMBJ130CA-M3/5B, and how does it affect layout?
The SMBJ130CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. This value assumes no additional heatsinking; designers must maintain adequate copper area and avoid thermal isolation to prevent junction temperatures exceeding 150 °C under sustained power dissipation.
How does the M3 suffix differ from the E3 suffix in SMBJ130CA-M3/5B?
The M3 suffix indicates halogen-free, RoHS-compliant construction using bromine-free flame retardants in the molding compound, whereas E3 denotes RoHS compliance with standard brominated flame retardants. Both share identical electrical specifications and packaging, but SMBJ130CA-M3/5B meets stricter environmental mandates such as China RoHS II and JEDEC J-STD-207.
