Product details
Overview
SMB10J15A-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 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 1 mA, 24.4 V clamping voltage (VC) at 41 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J15A-M3/5B datasheet, SMB10J15A-M3/5B pinout, SMB10J15A-M3/5B application, or SMB10J15A-M3/5B equivalent, key selection criteria include clamping performance under 41 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 unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below 15 V (VWM) and rapidly transitions to low-impedance conduction above its 16.7–18.5 V breakdown threshold. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5).
Thermally, it sustains 150 °C maximum junction temperature with derating above 25 °C ambient, supported by RθJL = 20 °C/W to leads and standard 0.2" × 0.2" copper pad layout. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12 V automotive systems. |
| VBR (Breakdown Voltage) | 16.7–18.5 V at 1 mA - Tight tolerance window ensures consistent turn-on across production lots and temperature range. |
| VC (Clamping Voltage) | 24.4 V at IPPM = 41 A - Limits downstream IC stress during 1000 W surge; enables robust protection of 24 V logic interfaces. |
| PPPM (Peak Pulse Power) | 1000 W (10/1000 µs) - Sustains high-energy transients common in load-dump and inductive switching events. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - Minimizes quiescent power loss and avoids false triggering in low-power sensor circuits. |
| TJ max. | 150 °C - Supports operation in under-hood automotive environments and industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - Surface-mount footprint (4.57 × 3.94 × 2.20 mm) compatible with automated placement and IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by color band on one end; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop when cathode is tied to protected line. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V supply or CAN_H); conducts surge current to ground during overvoltage event. |
Key Features
| Feature | Design Value |

| Halogen-free, RoHS-compliant (M3) | Meets environmental compliance mandates for Tier-1 automotive suppliers and industrial OEMs without compromising surge robustness. |
| Low incremental surge resistance | Enables tighter clamping (VC/VBR ratio = 1.46) versus legacy TVS devices, reducing voltage overshoot on sensitive MOSFET gates. |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free assembly without moisture-related popcorning or delamination risks. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage parameters across thermal cycling and humidity exposure. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-M3/5B | Same VWM (15 V), VBR (16.7–18.5 V), VC (24.4 V), but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; unsuitable for load-dump scenarios requiring >600 W dissipation | Select SMB10J15A-M3/5B where full 1000 W surge handling is mandated by system-level surge testing. |
| 1.5SMC15A-E3/57 | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W (vs. 72 °C/W) | Better thermal performance but requires 30% larger PCB area; incompatible with tight SMB footprints | Choose SMB10J15A-M3/5B when space-constrained layouts demand DO-214AA dimensions without sacrificing 1000 W rating. |

FAQ
What is the clamping voltage of SMB10J15A-M3/5B at its rated peak pulse current?
The SMB10J15A-M3/5B has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current (IPPM) of 41 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable voltage limiting during surge events - a critical parameter for protecting downstream 24 V-rated ICs and MOSFETs in the SMB10J15A-M3/5B application circuit.
Is SMB10J15A-M3/5B qualified for automotive use?
Yes, SMB10J15A-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 meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile - all required for automotive body control, lighting, and sensor modules where SMB10J15A-M3/5B is deployed.
What does the "/5B" suffix indicate in SMB10J15A-M3/5B?
The "/5B" suffix specifies the packaging configuration: 13-inch diameter plastic tape and reel containing 3200 units. This format supports high-volume SMT assembly lines and is distinct from "/52" (7-inch reel, 750 units). The "M3" prefix confirms halogen-free, RoHS-compliant materials - both elements are integral to the full orderable part number SMB10J15A-M3/5B and affect procurement and logistics planning.
How does SMB10J15A-M3/5B differ from bidirectional TVS diodes like SMB8J15CA?
SMB10J15A-M3/5B is unidirectional and optimized for DC rail protection with asymmetric conduction (cathode-to-anode forward bias), whereas SMB8J15CA is bidirectional and suited for AC or differential signal lines like RS-485 or CAN. SMB10J15A-M3/5B offers higher PPPM (1000 W vs. 800 W) and lower clamping ratio, making it preferable for 12 V/24 V power domains where polarity is fixed - a key distinction in SMB10J15A-M3/5B system integration.
What is the thermal resistance of SMB10J15A-M3/5B, and how does it impact layout design?
SMB10J15A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value necessitates adherence to Vishay's recommended pad layout to avoid thermal derating - undersized pads increase RθJA, risking junction overheating during repetitive surges. Proper thermal design is essential for sustained reliability of SMB10J15A-M3/5B in automotive and industrial applications.
