Product details
Overview
SMB10J17HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 17 V standoff voltage (VWM), 1000 W peak pulse power (10/1000 µs), 27.6 V clamping voltage at 36.2 A peak surge current, and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J17HE3/5B datasheet, SMB10J17HE3/5B pinout, SMB10J17HE3/5B application, or SMB10J17HE3/5B equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial I/O modules, and power supply input stages where fast response (<1 ns), low clamping ratio, and MSL Level 1 reflow compatibility are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 17 V; when exposed to transients exceeding its 18.9–20.9 V breakdown range (IT = 1 mA), it avalanches to clamp the line at ≤27.6 V. Its glass-passivated junction ensures stable performance across -55 °C to +150 °C operating temperature.
The device delivers 1000 W peak pulse power per 10/1000 µs waveform with 72 °C/W junction-to-ambient thermal resistance, requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for rated derating. It meets J-STD-020 MSL Level 1 (260 °C peak) and JESD201 Class 2 whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A-E3/5B | Same DO-214AA package, identical VWM/VC, but not AEC-Q101 qualified; lower surge test coverage. | Acceptable for commercial/industrial use only; excluded from automotive production BOMs requiring PPAP. | Select SMBJ17A-E3/5B only if AEC-Q101 is not mandated and cost sensitivity outweighs qualification requirements. |
| SMCJ17AHE3/5B | DO-214AB (SMC) package; same electrical specs but higher 1500 W PPPM; larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm). | Better suited for high-energy surges beyond 1000 W; requires PCB layout change and increased board area. | Choose SMCJ17AHE3/5B when system-level surge testing exceeds SMB10J17HE3/5B's 1000 W rating, and space permits larger package. |
Compared with SMBJ17A-E3/5B, SMB10J17HE3/5B adds AEC-Q101 validation for automotive use; compared with SMCJ17AHE3/5B, it delivers identical clamping performance in a 30 % smaller footprint-enabling denser layouts without sacrificing surge immunity.

FAQ
What is the maximum clamping voltage of SMB10J17HE3/5B at its rated peak pulse current?
The SMB10J17HE3/5B has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPPM) of 36.2 A under 10/1000 µs waveform conditions. This value is measured and guaranteed per Vishay Document Number 88422, ensuring predictable overvoltage limiting for protected circuits. The SMB10J17HE3/5B maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C) when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Is SMB10J17HE3/5B suitable for automotive applications?
Yes, SMB10J17HE3/5B is AEC-Q101 qualified and explicitly intended for automotive use, including engine control units, body electronics, and infotainment systems. Its qualification covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness per JESD22-A114. The SMB10J17HE3/5B also meets MSL Level 1 reflow requirements (260 °C peak), making it compatible with standard automotive SMT assembly processes without special handling.
How does the HE3 suffix differ from E3 in SMB10J17HE3/5B?
The HE3 suffix in SMB10J17HE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification, whereas E3 denotes RoHS compliance only for commercial-grade versions. The HE3 variant undergoes additional stress testing-including extended temperature cycling and bias-HAST-to validate reliability for automotive applications. Both share identical electrical parameters and DO-214AA packaging, but SMB10J17HE3/5B is certified for use in safety-critical vehicle subsystems where E3 parts are not approved.
What is the standoff voltage (VWM) and why is it important for SMB10J17HE3/5B?
The standoff voltage (VWM) of SMB10J17HE3/5B is 17 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures minimal leakage (<1 µA at 25 °C) during normal operation while providing sufficient margin below the 18.9–20.9 V breakdown range. Selecting SMB10J17HE3/5B for a 12 V system provides ~40 % headroom, preventing false triggering while allowing effective clamping during transients.
Does SMB10J17HE3/5B have polarity markings, and how is it oriented on the PCB?
Yes, SMB10J17HE3/5B is unidirectional and features a cathode band (dark stripe) on the package body, marking the cathode terminal. During PCB layout, the cathode must be connected to the line being protected (e.g., 12 V rail), and the anode to ground. Incorrect orientation renders the device non-functional as a shunt suppressor. The DO-214AA outline drawing in Vishay Document 88422 confirms the band position relative to lead geometry, and the SMB10J17HE3/5B datasheet specifies polarity-dependent parameters like forward surge current (IFSM = 100 A) only apply in correct orientation.
