Product details
Overview
SMB10J10-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 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 5.0 A peak pulse current, 1000 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMB10J10-E3/5B datasheet, SMB10J10-E3/5B pinout, SMB10J10-E3/5B application, or SMB10J10-E3/5B equivalent, this page delivers verified electrical parameters, mechanical package data, real-world protection use cases, and validated alternative parts - all aligned with Vishay's official 88422 specification document.
Technical Context
This TVS diode operates as a voltage-clamping device that remains non-conductive below its 10 V stand-off voltage (VWM) and rapidly transitions to low-impedance conduction when transients exceed its 11.1–12.3 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
The device delivers 1000 W peak pulse power handling per 10/1000 µs waveform, with a thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling effective heat dissipation during transient events without requiring external heatsinking in standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current; defines turn-on threshold |
| VC @ IPPM | 17.0 V - Clamping voltage seen across device at 5.0 A peak pulse current; limits downstream voltage stress |
| PPPM | 1000 W - Peak pulse power it can absorb without failure under standardized 10/1000 µs surge waveform |
| ID @ VWM | 5.0 µA - Reverse leakage current at rated stand-off voltage; ensures minimal standby power loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/5B | Same DO-214AA package, identical VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V); differs only in part numbering convention (SMBJ vs SMB10 prefix) | No functional difference; both rated for 1000 W PPPM and AEC-Q101 qualified | Select SMBJ10A-E3/5B if legacy BOM references SMBJ-series nomenclature; electrically interchangeable |
| 1.5SMC10A | Higher package thermal resistance (RθJA = 15 °C/W vs 72 °C/W), larger DO-214AB (SMC) footprint, same electrical specs but lower surge repetition capability due to thermal mass | Better suited for infrequent, high-energy surges; less ideal for compact, thermally constrained PCBs | Choose 1.5SMC10A only when board space allows larger SMC package and higher thermal margin is needed |
Compared with SMBJ10A-E3/5B, SMB10J10-E3/5B offers identical protection performance in the same footprint; versus 1.5SMC10A, it provides superior thermal efficiency and smaller board area, making it preferred for space-constrained automotive and industrial modules.

FAQ
What is the clamping voltage of SMB10J10-E3/5B at its rated peak pulse current?
The SMB10J10-E3/5B has a maximum clamping voltage (VC) of 17.0 V when subjected to its specified peak pulse current of 5.0 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable overvoltage limiting for downstream circuitry. The SMB10J10-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMB10J10-E3/5B suitable for automotive applications?
Yes, SMB10J10-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and glass-passivated junction meet stringent automotive reliability requirements. The SMB10J10-E3/5B datasheet confirms qualification per the AEC-Q101 standard.
What does the "E3/5B" suffix indicate in SMB10J10-E3/5B?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "5B" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This configuration supports high-speed automated assembly and complies with IPC/JEDEC standards. The SMB10J10-E3/5B ordering code is fully defined in Vishay document 88422.
How does SMB10J10-E3/5B differ from bi-directional variants like SMB8J10CA?
SMB10J10-E3/5B is unidirectional with anode-cathode polarity and clamps only positive transients relative to ground, whereas SMB8J10CA is bi-directional and protects against both polarities. SMB10J10-E3/5B offers higher peak pulse power (1000 W vs 800 W) and is optimized for DC power rail protection. The SMB10J10-E3/5B cannot substitute for bi-directional use without circuit redesign.
What is the thermal resistance of SMB10J10-E3/5B, and how does it affect layout?
SMB10J10-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W. These values assume mounting on 0.2" × 0.2" copper pads per terminal. To maintain safe junction temperatures during repeated surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks - the SMB10J10-E3/5B thermal performance is validated per JEDEC standards.
