Product details
Overview
SMB10J17HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection with 1000 W peak pulse power rating, 17 V standoff voltage (VWM), and 27.6 V maximum clamping voltage at 36.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive power electronics and sensor signal lines against inductive switching transients.
For engineers reviewing the SMB10J17HE3/52 datasheet, SMB10J17HE3/52 pinout, SMB10J17HE3/52 application, or SMB10J17HE3/52 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity, RoHS-compliant AEC-Q101 qualification, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its 18.9–20.9 V breakdown range (VBR at 1 mA). Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for safeguarding MOSFETs and ICs from ESD and load-dump events.
Designed for surface-mount use in automotive ECUs and industrial controllers, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and supports operation from –55 °C to +150 °C junction temperature.
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-E3/52 | Same DO-214AA package, identical VWM (17 V) and VC (27.6 V), but rated for 600 W PPPM (vs. 1000 W). | Not suitable for automotive load-dump where 1000 W capability is required per ISO 16750-2. | Select SMB10J17HE3/52 when full 1000 W surge handling is mandatory; SMBJ17A-E3/52 suffices for lower-energy ESD/EFT scenarios. |
| SMCJ17AHE3/52 | DO-214AB (SMC) package, same electrical specs, but higher thermal mass and RθJA = 35 °C/W (vs. 72 °C/W). | Better sustained surge energy handling but requires larger PCB footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm). | Choose SMB10J17HE3/52 for space-constrained automotive modules; SMCJ17AHE3/52 where board area allows and thermal margin is critical. |
Compared with SMBJ17A-E3/52 and SMCJ17AHE3/52, SMB10J17HE3/52 uniquely delivers 1000 W surge capability in the compact DO-214AA footprint with AEC-Q101 qualification-making it optimal for high-density, high-reliability automotive power node protection where both size and ruggedness are non-negotiable.

FAQ
What is the clamping voltage of SMB10J17HE3/52 at its rated peak pulse current?
The SMB10J17HE3/52 has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPPM) of 36.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during surge events. The SMB10J17HE3/52 achieves this with low incremental resistance, minimizing voltage overshoot beyond VC.
Is SMB10J17HE3/52 suitable for automotive applications?
Yes, SMB10J17HE3/52 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction-glass-passivated junction, matte tin leads meeting JESD 201 Class 2, MSL Level 1 rating, and operation from –55 °C to +150 °C-meets stringent automotive reliability requirements. The SMB10J17HE3/52 data sheet confirms qualification per AEC-Q101 test conditions.
What does the "HE3" suffix indicate in SMB10J17HE3/52?
The "HE3" suffix in SMB10J17HE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. "H" signifies AEC-Q101 qualification, "E3" indicates RoHS compliance and commercial-grade reliability per Vishay's material categorization. This distinguishes it from "E3"-only variants (e.g., SMB10J17E3/52), which lack automotive qualification. The SMB10J17HE3/52 is therefore specified for mission-critical automotive deployments.
How does SMB10J17HE3/52 differ from SMBJ17A-E3/52?
SMB10J17HE3/52 delivers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ17A-E3/52, while sharing identical VWM (17 V), VBR, and VC (27.6 V). Both use DO-214AA packaging, but only SMB10J17HE3/52 carries AEC-Q101 qualification. The SMB10J17HE3/52 is intended for high-energy automotive transients (e.g., ISO 16750-2 load dump), whereas SMBJ17A-E3/52 targets general-purpose ESD/EFT protection.
What is the thermal resistance of SMB10J17HE3/52, and how does it affect layout?
The SMB10J17HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions; reducing pad area increases RθJA, raising junction temperature during repetitive surges. For reliable operation in automotive environments, maintain minimum pad dimensions and consider thermal vias under the cathode/anode pads. The SMB10J17HE3/52 datasheet specifies these layout rules to ensure thermal performance.
