Product details
Overview
SMB10J10HE3/5B 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. It protects MOSFETs and ICs against inductive switching transients in engine control units.
For engineers reviewing the SMB10J10HE3/5B datasheet, SMB10J10HE3/5B pinout, SMB10J10HE3/5B application, or SMB10J10HE3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surges, unidirectional polarity with cathode band marking, RoHS-compliant AEC-Q101 qualification, 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 its breakdown threshold (11.1–12.3 V at 1 mA), it avalanches to divert surge current away from downstream circuitry. Its low incremental surge resistance ensures stable clamping during high-current transients up to 58.8 A (10/1000 µs).
The device uses a glass-passivated silicon junction for robustness, achieves MSL Level 1 moisture sensitivity per J-STD-020, and maintains operation from –55 °C to +150 °C junction temperature. Its thermal resistance (RθJA = 72 °C/W) reflects standard SMB package dissipation capability on recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working range for protected line. |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - Breakdown voltage tolerance band; determines earliest clamping onset under surge conditions. |
| VC @ IPPM | 17.0 V at 5.0 A - Clamping voltage during standardized 10/1000 µs surge; directly limits voltage seen by protected IC or MOSFET. |
| PPPM | 1000 W - Peak pulse power handling (10/1000 µs); quantifies single-event surge energy absorption capacity. |
| ID @ VWM | 5.0 µA - Reverse leakage at rated stand-off voltage; low value minimizes standby power loss and signal distortion. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with high ambient thermal stress. |
| Qualification | AEC-Q101 qualified - Validated for automotive electronic systems requiring proven reliability across temperature cycling, humidity, and mechanical shock. |

Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Power Stage |
|---|---|
Use Scenario: Protects microcontroller I/O and gate drivers from load dump and inductive kickback during solenoid/relay switching. IC Role / Device Role: Unidirectional shunt TVS placed between MCU supply rail and chassis ground. Use Value: Limits transient voltage to ≤17.0 V, preventing latch-up or oxide damage in 3.3 V/5 V logic interfaces. |
Use Scenario: Shields IGBT gate driver inputs from Miller-induced spikes during high-dI/dt switching in variable-frequency drives. IC Role / Device Role: Clamp diode mounted directly at gate resistor input to suppress >100 V transients. Use Value: Fast response (<1 ps) and low clamping voltage ensure gate oxide remains below 20 V stress threshold. |
| Telecom Base Station DC Power Input | Automotive Body Control Module (BCM) |
Use Scenario: Guards primary 48 V DC input against lightning-induced surges and hot-swap transients. IC Role / Device Role: First-line unidirectional TVS upstream of DC-DC converter input filter. Use Value: 1000 W rating handles 10/1000 µs surges up to 58.8 A while maintaining <17.0 V clamping at system ground reference. |
Use Scenario: Safeguards LIN bus transceivers and LED driver ICs from battery reversal and jump-start surges. IC Role / Device Role: Bidirectional protection not applicable; this unidirectional part used on VBAT-to-ground paths only. Use Value: AEC-Q101 qualification and –55 °C to +150 °C operation ensure compliance with automotive environmental test requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/5B | Same DO-214AA package, identical VWM (10 V) and VC (17.0 V), but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-current load dump scenarios. | Select SMB10J10HE3/5B when full 1000 W surge immunity is required; SMBJ10A-E3/5B suffices for basic ESD and low-energy switching noise. |
| SMCJ10AHE3/5B | DO-214AB (SMC) package, same VWM/VC specs, rated for 1500 W PPPM and higher IPPM (92.6 A). | Physically larger footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm); requires more PCB area and higher thermal mass. | Choose SMCJ10AHE3/5B only when 1500 W surge margin is mandatory and board space permits larger SMC package. |

The SMB10J10HE3/5B has a maximum clamping voltage (VC) of 17.0 V when subjected to its specified peak pulse current of 5.0 A 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. The SMB10J10HE3/5B maintains this clamping performance across its qualified operating temperature range.
Is SMB10J10HE3/5B suitable for automotive applications?
Yes, SMB10J10HE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body control modules. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C. The SMB10J10HE3/5B meets the reliability and environmental stress requirements defined in the AEC-Q101 standard for discrete semiconductors.
What does the "HE3" suffix indicate in SMB10J10HE3/5B?
The "HE3" suffix in SMB10J10HE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial-only "E3" variants. The SMB10J10HE3/5B is intended for high-reliability applications where long-term intermetallic stability and automotive qualification are mandatory.
How does SMB10J10HE3/5B differ from SMBJ10A-E3/5B?
SMB10J10HE3/5B offers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ10A-E3/5B, while sharing identical VWM (10 V), VC (17.0 V), and DO-214AA package dimensions. The SMB10J10HE3/5B also carries AEC-Q101 qualification, whereas SMBJ10A-E3/5B is commercial-grade only. These differences make SMB10J10HE3/5B appropriate for demanding automotive and industrial surge environments.
What is the maximum reverse leakage current for SMB10J10HE3/5B at its stand-off voltage?
The SMB10J10HE3/5B exhibits a maximum reverse leakage current (ID) of 5.0 µA when biased at its 10 V stand-off voltage (VWM) and tested at 25 °C.
