Product details
Overview
SMB10J15-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power and signal lines. It features a 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR), 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 - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMB10J15-E3/5B datasheet, SMB10J15-E3/5B pinout, SMB10J15-E3/5B application, or SMB10J15-E3/5B equivalent, key selection criteria include clamping performance under 1000 W surges, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its breakdown threshold to divert transient energy away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, enabling fast response to ESD and inductive switching transients.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with RθJA = 72 °C/W and RθJL = 20 °C/W, supporting reliable performance in compact PCB layouts. The device meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing due to its E3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 16.7 V / 18.5 V at 1.0 mA - verified breakdown range ensuring consistent turn-on across production lots. |
| VC @ IPPM | 24.4 V at 41.0 A - clamping voltage during full 1000 W surge; limits stress on protected MOSFETs or microcontrollers. |
| PPPM | 1000 W (10/1000 µs) - peak pulse power rating defining maximum transient energy absorption capability. |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage preserves efficiency in battery-powered or high-impedance sensor circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-E3/5B | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or telecom lightning tests. | Select SMBJ15A-E3/5B only where surge threat level is defined below 600 W and cost optimization is critical. |
| 1.5SMC15A | DO-214AB (SMC) package, 1000 W rating, but 7.2 mm × 6.2 mm footprint - 2.5× larger area than SMB10J15-E3/5B. | Requires significant PCB real estate; incompatible with dense automotive module layouts. | Choose 1.5SMC15A only when thermal dissipation demands larger case or legacy board compatibility mandates SMC outline. |
Compared with SMBJ15A-E3/5B and 1.5SMC15A, SMB10J15-E3/5B delivers full 1000 W surge handling in the smallest qualified footprint, making it optimal for AEC-Q101-compliant automotive modules and space-constrained industrial controllers where both power density and reliability are non-negotiable.

FAQ
What is the clamping voltage of SMB10J15-E3/5B at its rated peak pulse current?
The SMB10J15-E3/5B exhibits a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current of 41.0 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 downstream components like microcontrollers or power MOSFETs in the SMB10J15-E3/5B-protected circuit.
Is SMB10J15-E3/5B suitable for automotive applications?
Yes, SMB10J15-E3/5B is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS power supplies. Its construction - glass-passivated junction, MSL Level 1 rating, JESD 201 Class 1A whisker resistance, and operation from –55 °C to +150 °C - meets stringent automotive reliability requirements confirmed in the Vishay qualification report for the SMB10J series.
What does the "E3/5B" suffix indicate in SMB10J15-E3/5B?
The "E3" denotes RoHS-compliant, commercial-grade matte tin plating meeting JESD 201 Class 1A whisker resistance, while "5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This format supports high-speed pick-and-place assembly and aligns with IPC-7351 land pattern recommendations for DO-214AA (SMB) footprints used in SMB10J15-E3/5B production builds.
How does SMB10J15-E3/5B differ from bi-directional variants like SMB8J15CA?
SMB10J15-E3/5B is unidirectional with cathode-band polarity, optimized for DC rail protection where reverse conduction is not required. In contrast, SMB8J15CA is bi-directional, offering symmetrical clamping for AC-coupled or floating signal lines. SMB10J15-E3/5B provides higher peak pulse power (1000 W vs. 800 W) and lower clamping impedance - a deliberate trade-off favoring DC power line robustness over bidirectional symmetry in the SMB10J15-E3/5B design.
What is the thermal resistance from junction to ambient for SMB10J15-E3/5B?
The typical thermal resistance from junction to ambient (RθJA) for SMB10J15-E3/5B is 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet (Document Number: 88422). This value assumes standard JEDEC test board conditions and directly impacts maximum allowable power dissipation in thermally constrained layouts using SMB10J15-E3/5B.
