Product details
Overview
SMA5J17HE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on DC power lines and signal paths. It features a 17 V standoff voltage (VWM), 18.9–20.9 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 µs), clamping voltage of 27.6 V at 18.1 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J17HE3/61 datasheet, SMA5J17HE3/61 pinout, SMA5J17HE3/61 application, or SMA5J17HE3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, low incremental surge resistance, RoHS-compliant matte tin-plated leads, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below VWM = 17 V and rapidly transitions to low-impedance conduction above VBR (min 18.9 V) to limit transient overvoltages. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable breakdown behavior under repetitive surge stress.
The device delivers 500 W peak pulse power handling with a 10/1000 µs waveform, supported by thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W. It is rated for -55 °C to +150 °C operating junction temperature and meets JESD201 Class 2 whisker testing due to its HE3 suffix.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J17A-E3/61 | Commercial grade (non-AEC-Q101); same VWM/VBR/PPPM specs; JESD201 Class 1A whisker test | Lacks automotive qualification; suitable for consumer/industrial but not safety-critical vehicle systems | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMB5J17AHE3/61 | Same electrical specs but SMB (DO-214AA) package - 25 % larger footprint, lower RθJA (65 °C/W) | Better thermal performance in high-ambient or high-duty-cycle surge environments | Choose when board space allows and thermal derating margin is critical |
Compared with SMA5J17A-E3/61, the SMA5J17HE3/61 adds AEC-Q101 qualification and Class 2 whisker resistance, making it mandatory for automotive deployment; versus SMB5J17AHE3/61, it trades thermal margin for compact DO-214AC layout - ideal where PCB area is constrained but ambient temperature stays ≤105 °C.

FAQ
What is the maximum clamping voltage of the SMA5J17HE3/61 during a 500 W surge event?
The SMA5J17HE3/61 clamps to 27.6 V at its peak pulse current (IPPM) of 18.1 A under a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMA5J17HE3/61 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), ensuring consistent protection in demanding environments.
Is the SMA5J17HE3/61 suitable for automotive applications?
Yes, the SMA5J17HE3/61 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS subsystems. Its HE3 suffix denotes AEC-Q101 qualification, JESD201 Class 2 whisker resistance, and compliance with MSL Level 1 reflow requirements. The SMA5J17HE3/61 also supports operation up to +150 °C junction temperature, meeting under-hood thermal demands.
What does the "HE3" suffix indicate in SMA5J17HE3/61?
The "HE3" suffix in SMA5J17HE3/61 identifies a RoHS-compliant, AEC-Q101-qualified version with JESD201 Class 2 whisker resistance. It distinguishes the part from commercial-grade "E3" variants (e.g., SMA5J17A-E3/61) and confirms enhanced reliability testing for automotive deployment. The SMA5J17HE3/61 uses matte tin-plated leads solderable per J-STD-002 and JESD22-B102 standards.
How does the SMA5J17HE3/61 differ from the SMA5J17A-E3/61?
The SMA5J17HE3/61 adds AEC-Q101 qualification and JESD201 Class 2 whisker resistance compared to the SMA5J17A-E3/61, which is commercial-grade with Class 1A whisker testing. Electrically, both share identical VWM (17 V), VBR (18.9–20.9 V), PPPM (500 W), and package (DO-214AC). The SMA5J17HE3/61 is required for automotive applications; the SMA5J17A-E3/61 suffices for industrial or consumer use.
What is the thermal resistance of the SMA5J17HE3/61, and how does it affect layout design?
The SMA5J17HE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W. These values require minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 500 W performance. Layouts must ensure adequate copper area and avoid thermal bottlenecks to prevent junction temperature exceedance during repetitive surges. The SMA5J17HE3/61 thermal data is validated per JEDEC test conditions.
