Product details
Overview
SMB10J15-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) 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 41.0 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMB10J15-E3/52 datasheet, SMB10J15-E3/52 pinout, SMB10J15-E3/52 application, or SMB10J15-E3/52 equivalent, key selection criteria include clamping performance under 41 A surge, unidirectional polarity for DC rail protection, RoHS-compliant matte tin terminations, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM), while its low incremental surge resistance enables rapid response to ESD and lightning-induced transients.
The device is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation in thermally constrained PCB layouts. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse working voltage before clamping begins; defines safe DC rail operating margin. |
| VBR (min/max) | 16.7 V / 18.5 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across production lot. |
| VC @ IPPM | 24.4 V at 41.0 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected circuitry. |
| PPPM | 1000 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity design. |
| ID @ VWM | <1.0 µA - Reverse leakage at rated stand-off; minimizes standby power loss in battery-powered systems. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline with cathode band marking; compatible with JEDEC MS-012AC footprint. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode indicated by a color band on the body. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point; completes shunt path during transient event. |
| Cathode | High-side surge input node | Connected to protected line (e.g., 12 V rail or sensor output); receives transient energy prior to clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM ≥ 8 kV. |
| Glass passivated junction | Ensures stable VBR over lifetime and improved humidity resistance versus epoxy-passivated alternatives. |
| MSL Level 1 rating | Allows unlimited floor life and reflow up to 260 °C peak without baking-enables direct placement in high-volume SMT lines. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio TVS devices in same power class. |
| RoHS-compliant, matte tin terminations | Meets J-STD-002 solderability and JESD 22-B102 intermetallic formation standards for lead-free assembly. |

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-E3/52 | Same DO-214AA package, identical VWM (15 V), but lower PPPM (600 W) and VC (24.4 V @ 24.7 A). | Lower surge capacity limits use to sub-IEC Level 3 environments; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or 1000 W surge requirement. |
| 1.5SMC15A | DO-214AB (SMC) package, larger footprint, same electrical specs (VWM = 15 V, VC = 24.4 V), higher thermal mass. | Requires PCB redesign; better suited for high-temperature ambient (>125 °C) or high-reliability industrial systems. | Choose when board space allows larger package and enhanced thermal derating is needed for sustained surge duty cycles. |
Compared with SMBJ15A-E3/52 and 1.5SMC15A, SMB10J15-E3/52 uniquely delivers 1000 W surge rating in the compact SMB outline while maintaining AEC-Q101 compliance-making it optimal for space-constrained automotive and industrial modules requiring full IEC 61000-4-5 Level 4 immunity.

FAQ
What is the clamping voltage of SMB10J15-E3/52 under a 10/1000 µs surge?
The SMB10J15-E3/52 clamps to a maximum of 24.4 V when subjected to its rated peak pulse current of 41.0 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88422, ensuring predictable overvoltage limiting for protected circuits.
Is SMB10J15-E3/52 suitable for automotive applications?
Yes, SMB10J15-E3/52 is AEC-Q101 qualified and tested for high-temperature operation up to +150 °C junction temperature. Its glass-passivated junction, MSL Level 1 rating, and JESD 201 Class 1A whisker resistance make SMB10J15-E3/52 appropriate for under-hood ECUs, body control modules, and ADAS sensor interfaces.
What does the "-E3/52" suffix indicate in SMB10J15-E3/52?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin terminations; "/52" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This format ensures compatibility with standard SMT pick-and-place equipment and supports high-volume manufacturing.
How does SMB10J15-E3/52 differ from bi-directional variants like SMB8J15CA?
SMB10J15-E3/52 is unidirectional and optimized for DC rail protection with 1000 W PPPM, whereas SMB8J15CA is bi-directional with 800 W PPPM and symmetrical breakdown. The unidirectional SMB10J15-E3/52 offers lower leakage (<1.0 µA) and higher surge current (41.0 A vs. 32.8 A), making it preferable for polarized power lines.
What PCB layout guidance applies to SMB10J15-E3/52 for optimal thermal performance?
For rated 1000 W pulse handling, Vishay specifies mounting SMB10J15-E3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Minimizing trace length between the device and protected node, and using internal ground/power planes, reduces inductance and improves clamping response during fast transients.
