Product details
Overview
SMA5J10HE3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, rated for 10 V standoff voltage, 17.0 V clamping voltage at 29.4 A peak pulse current, and 500 W peak pulse power with 10/1000 µs waveform. It provides robust ESD and surge protection for automotive power rails and sensor interfaces.
For engineers reviewing the SMA5J10HE3/5A datasheet, SMA5J10HE3/5A pinout, SMA5J10HE3/5A application, or SMA5J10HE3/5A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This device operates as a silicon avalanche diode designed to clamp transient overvoltages before they damage downstream circuitry. Its glass-passivated junction ensures stable breakdown behavior and long-term reliability under repetitive surge stress.
It delivers fast response time (<1 ns), low clamping ratio (VC/VWM = 1.7), and thermal resistance of 80 °C/W (junction-to-ambient) when mounted on 5.0 mm × 5.0 mm copper pads - critical for sustained surge handling in automotive ECUs and industrial power supplies.

| VBR min/max | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current, ensuring predictable turn-on |
| VC @ IPPM | 17.0 V - Clamped voltage during 29.4 A 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 500 W - Peak pulse power capability defines maximum transient energy absorption per event |
| TJ max | +150 °C - Enables operation in under-hood automotive environments without derating |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling and HTRB |

FAQ
What is the clamping voltage of the SMA5J10HE3/5A at its rated peak pulse current?
The SMA5J10HE3/5A has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 29.4 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry sees no more than 17.0 V during such transients. The SMA5J10HE3/5A maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is the SMA5J10HE3/5A suitable for automotive applications?
Yes, the SMA5J10HE3/5A is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and infotainment power supplies. Its HE3 suffix denotes AEC-Q101 qualification, JESD 201 class 2 whisker resistance, and RoHS compliance. The SMA5J10HE3/5A meets all stress tests defined in the AEC-Q101 standard, including temperature cycling, highly accelerated life testing, and surge robustness.
What does the "HE3" suffix mean in SMA5J10HE3/5A?
The "HE3" suffix in SMA5J10HE3/5A indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. It distinguishes this part from commercial-grade variants (e.g., E3-only), confirming suitability for automotive and high-reliability industrial applications. The SMA5J10HE3/5A also features matte tin-plated leads solderable per J-STD-002 and complies with MSL Level 1 reflow requirements.
How does the SMA5J10HE3/5A differ from the SMA5J10A-E3/5A?
The SMA5J10HE3/5A and SMA5J10A-E3/5A share identical electrical specifications and DO-214AC packaging, but the HE3 version adds AEC-Q101 qualification and JESD 201 class 2 whisker resistance. The SMA5J10HE3/5A is intended for automotive applications requiring certified reliability, whereas the SMA5J10A-E3/5A is rated for commercial/industrial use only. Both parts have the same 10 V standoff and 17.0 V clamping voltage.
What is the maximum junction temperature rating for the SMA5J10HE3/5A?
The SMA5J10HE3/5A has a maximum junction temperature (TJ) rating of +150 °C, enabling reliable operation in under-hood automotive environments and high-temperature industrial enclosures. This rating is maintained across its full specified storage temperature range of -55 °C to +150 °C and supports uninterrupted functionality during extended thermal stress events. The SMA5J10HE3/5A's thermal resistance (RθJA) is 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads.
