Product details
Overview
SMB10J13A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V maximum clamping voltage (VC) at 46.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J13A-M3/5B datasheet, SMB10J13A-M3/5B pinout, SMB10J13A-M3/5B application, or SMB10J13A-M3/5B equivalent, key selection criteria include clamping performance under 46.5 A surge, thermal resistance (RθJA = 72 °C/W), AEC-Q101 qualification status, and halogen-free RoHS compliance per M3 suffix - critical for automotive-grade ECU and ADAS module designs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (14.4–15.9 V), it avalanches to divert transient energy away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response (<1 ns), while low incremental surge resistance enables consistent clamping at VC = 21.5 V under 10/1000 µs stress.
The SMB10J13A-M3/5B is rated for TJ = –55 °C to +150 °C operation, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and supports automated SMT placement via matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 - enabling direct integration into high-reliability automotive PCBs without derating penalties below 80 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12 V automotive systems. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - precise avalanche initiation threshold ensuring predictable turn-on during transients. |
| VC (Clamping Voltage) | 21.5 V at IPPM = 46.5 A - peak voltage seen by protected circuit during 1000 W surge; limits stress on 24 V-rated downstream MOSFETs. |
| PPPM (Peak Pulse Power) | 1000 W (10/1000 µs) - energy-handling capacity sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - negligible standby current draw, preserving battery life in always-on vehicle modules. |
| TJ max. | +150 °C - enables operation in engine bay environments without thermal shutdown or parameter drift. |
| AEC-Q101 Qualified | Yes - validated for automotive electronic control units per stress test requirements including HTGB, HTRB, and temperature cycling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile (max height 2.20 mm), UL 94 V-0 molded compound, cathode indicated by band on end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or low-side return path; enables unidirectional clamping from rail-to-ground. |
| Cathode | Current exit terminal during reverse avalanche | Connected to protected line (e.g., 12 V supply); conducts surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free & RoHS-compliant (M3 suffix) | Meets automotive environmental mandates and soldering process compatibility for lead-free reflow (260 °C peak). |
| AEC-Q101 qualified | Validated for automotive under-hood applications including extended temperature cycling and high-humidity bias testing. |
| Low incremental surge resistance | Enables tight clamping window (VC − VBR ≈ 7.1 V), minimizing overvoltage exposure to sensitive CAN transceivers or microcontrollers. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage across 15-year automotive service life with no parameter drift. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing without baking, reducing manufacturing overhead in Tier-1 assembly lines. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-M3/5B | Same VWM (13 V), VBR (14.4–15.9 V), and VC (21.5 V), but lower PPPM = 600 W (per SMBJ family spec). | Not suitable for ISO 7637-2 Pulse 5a (load dump) requiring ≥1000 W; limited to lower-energy transients like ESD or relay bounce. | Select SMB10J13A-M3/5B when full 1000 W surge immunity is required; SMBJ13A-M3/5B only where space or cost constraints override power rating needs. |
| SMCJ13A-M3/5B | Same electrical specs but in larger SMC (DO-214AB) package - higher thermal mass, RθJA = 30 °C/W vs. 72 °C/W. | Better sustained power handling and lower junction temperature rise, but requires 30% more PCB area and incompatible footprint. | Choose SMB10J13A-M3/5B for space-constrained automotive modules; SMCJ13A-M3/5B only if thermal margin is insufficient in SMB layout. |
Compared with SMBJ13A-M3/5B and SMCJ13A-M3/5B, SMB10J13A-M3/5B uniquely delivers 1000 W surge capability in the compact SMB footprint - balancing automotive-grade robustness, AEC-Q101 validation, and board-area efficiency where thermal design allows RθJA = 72 °C/W.

FAQ
What is the clamping voltage of SMB10J13A-M3/5B at its rated peak pulse current?
The SMB10J13A-M3/5B has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current (IPPM) of 46.5 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for protected circuits - a critical parameter verified in every SMB10J13A-M3/5B production lot.
Is SMB10J13A-M3/5B qualified for automotive applications?
Yes, SMB10J13A-M3/5B is AEC-Q101 qualified, as confirmed by Vishay's official documentation (Document Number: 88422, Revision: 09-Jan-2024). The "M3" suffix denotes halogen-free, RoHS-compliant construction, and the device undergoes full stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - making SMB10J13A-M3/5B suitable for engine control units, body electronics, and ADAS systems.
What does the "/5B" in SMB10J13A-M3/5B indicate?
The "/5B" suffix in SMB10J13A-M3/5B specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This format supports high-volume SMT assembly and is compatible with standard pick-and-place equipment - distinct from "/52" (7-inch reel, 750 units) and essential for production planning when ordering SMB10J13A-M3/5B.
How does SMB10J13A-M3/5B differ from bidirectional variants like SMB10J13CA-M3/5B?
SMB10J13A-M3/5B is unidirectional and protects against positive-going transients only (anode-to-cathode), while SMB10J13CA-M3/5B is bidirectional and suppresses surges of either polarity. The unidirectional SMB10J13A-M3/5B offers higher peak pulse power (1000 W vs. 800 W for the bidirectional version) and lower clamping voltage in DC-biased applications - making SMB10J13A-M3/5B preferred for 12 V supply rail protection where polarity is fixed.
What is the maximum operating junction temperature for SMB10J13A-M3/5B?
The SMB10J13A-M3/5B has a maximum operating junction temperature (TJ max.) of +150 °C, as specified in Vishay's datasheet (Document Number: 88422). This rating enables reliable operation in under-hood automotive environments and industrial enclosures without thermal derating up to 80 °C ambient - a key advantage over commercial-grade TVS diodes limited to +125 °C, and directly validated for SMB10J13A-M3/5B in AEC-Q101 testing.
