Product details
Overview
SMB10J15A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (VBR), and 1000 W peak pulse power (10/1000 µs). It clamps transients to ≤24.4 V at 41 A peak surge current and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the SMB10J15A-E3/5B datasheet, SMB10J15A-E3/5B pinout, SMB10J15A-E3/5B application, or SMB10J15A-E3/5B equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, 72 °C/W junction-to-ambient thermal resistance, and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, leveraging avalanche breakdown to limit transient overvoltages. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges per IEC 61000-4-2/4-5.
Rated for -55 °C to +150 °C operation, SMB10J15A-E3/5B uses a low-profile SMB package with MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility. The cathode band marking identifies polarity, and its 100 A IFSM rating supports robust handling of 8.3 ms half-sine surge events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-E3/52 | Same VWM/VBR/PPPM, but rated for 750-unit tape-and-reel (vs. 3200 for SMB10J15A-E3/5B) | Identical electrical performance; differs only in packaging format and reel size | Select SMBJ15A-E3/52 for smaller batch prototyping or legacy reel-handling systems |
| 1.5SMC15A | Higher package thermal resistance (RθJA = 11 °C/W vs. 72 °C/W), lower PPPM (1500 W but in larger SMC package) | Requires larger PCB footprint; less suitable for dense automotive modules | Choose 1.5SMC15A only if higher surge margin is needed and board space permits larger SMC (DO-214AB) footprint |
Compared with SMBJ15A-E3/52 and 1.5SMC15A, SMB10J15A-E3/5B delivers identical clamping performance in a smaller SMB footprint with optimized thermal resistance for high-density layouts, while its 3200-unit reel supports high-volume automotive production runs.

FAQ
What is the maximum clamping voltage of SMB10J15A-E3/5B at its rated peak pulse current?
The SMB10J15A-E3/5B clamps to a maximum of 24.4 V when subjected to its rated 41 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream components remain within safe operating limits.
Is SMB10J15A-E3/5B suitable for automotive applications?
Yes, SMB10J15A-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and operation from -55 °C to +150 °C - all validated per automotive reliability standards. The "HE3" suffix variant is designated for automotive, but SMB10J15A-E3/5B meets the same electrical and environmental specs.
How does the SMB10J15A-E3/5B differ from the SMBJ15A series?
SMB10J15A-E3/5B and SMBJ15A share identical electrical parameters (VWM, VBR, VC, PPPM) and SMB package, but SMB10J15A-E3/5B is part of Vishay's higher-surge-current 1000 W family with tighter thermal resistance control. The "10" prefix denotes enhanced power handling consistency, and the -E3/5B suffix specifies 3200-unit 13-inch reel packaging optimized for high-volume SMT lines.
What is the reverse leakage current specification for SMB10J15A-E3/5B at its standoff voltage?
At its 15 V standoff voltage (VWM), the SMB10J15A-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage preserves system efficiency in always-on automotive modules and avoids loading sensitive analog sensor references, making it suitable for low-power and precision applications.
Can SMB10J15A-E3/5B be used in bidirectional configurations?
No - SMB10J15A-E3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection at 15 V standoff, the correct variant is SMB10J15CA (with "C" suffix), which provides symmetrical clamping for AC-coupled or floating signal lines. Using SMB10J15A-E3/5B in bidirectional roles risks forward conduction and failure during negative transients.
