Product details
Overview
SMA5J10AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage at 29.4 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive ECUs, industrial I/O ports, and sensor interfaces against ESD and load dump transients.
For engineers reviewing the SMA5J10AHE3_A/H datasheet, SMA5J10AHE3_A/H pinout, SMA5J10AHE3_A/H application, or SMA5J10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below 10 V (VWM) and rapidly avalanches above its 11.1–12.3 V breakdown threshold to limit transient voltages. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time under sub-nanosecond ESD events.
Rated for 500 W peak pulse power (10/1000 µs), it delivers 29.4 A IPPM with 17.0 V VC while maintaining thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead). The device is qualified to AEC-Q101 and meets MSL level 1 (260 °C reflow peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 11.1 V / 12.3 V - guaranteed avalanche onset range at 1 mA test current |
| VC @ IPPM | 17.0 V - clamped voltage during 29.4 A 10/1000 µs surge, defining protected circuit voltage ceiling |
| PPPM | 500 W - peak transient energy absorption capability per single pulse |

| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SMA5J10AHE3_A/H uses the standard SMA (DO-214AC) package: molded plastic case with two leads, cathode identified by a band at one end. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. Mounting requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-impedance reference in unidirectional clamp configuration |
| Cathode | Reverse-biased terminal / clamping node | Connected to protected line; conducts when transient exceeds VBR to shunt energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMA package | Enables high-density PCB layouts and compatibility with automated pick-and-place equipment |
| Glass-passivated junction | Ensures stable reverse leakage (<1.0 µA at VWM) and long-term parameter consistency across temperature |
| 500 W peak pulse power | Provides robust protection against ISO 7637-2 load dump pulses and IEC 61000-4-5 surges in automotive systems |
| AEC-Q101 qualification | Validates suitability for under-hood and body-control module applications requiring automotive reliability |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without moisture-related damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10A-E3/61 | Commercial-grade version without AEC-Q101 qualification; identical electrical specs and SMA package | Approved for industrial/commercial use only; not certified for automotive production | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMA6J10AHE3_A/H | 600 W PPPM rating (vs. 500 W), same VWM/VBR/VC, identical AEC-Q101 qualification and SMA package | Higher surge margin for designs facing repeated or severe transients (e.g., heavy-duty vehicle systems) | Choose when system-level testing requires >500 W pulse handling without layout change |
Compared with SMA5J10A-E3/61, SMA5J10AHE3_A/H adds automotive qualification without altering electrical behavior; versus SMA6J10AHE3_A/H, it trades 100 W pulse capacity for tighter thermal design margins and lower cost in less demanding environments.

FAQ
What is the polarity configuration of SMA5J10AHE3_A/H?
SMA5J10AHE3_A/H is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the SMA (DO-214AC) package body, and it conducts only when the cathode is biased positively relative to the anode - making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like SMA5J10CA, which suppress surges regardless of polarity.
Does SMA5J10AHE3_A/H meet automotive qualification standards?
Yes, SMA5J10AHE3_A/H is fully AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024 (Document Number: 88875). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its use in automotive body electronics and powertrain subsystems.
What is the maximum clamping voltage of SMA5J10AHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of SMA5J10AHE3_A/H is 17.0 V when subjected to its rated peak pulse current of 29.4 A with a 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
Can SMA5J10AHE3_A/H be used in place of SMA5J10A-E3/61 without design changes?
Yes - SMA5J10AHE3_A/H shares identical electrical characteristics, pinout, and SMA (DO-214AC) package dimensions with SMA5J10A-E3/61. The only difference is AEC-Q101 qualification; no PCB layout, thermal pad, or schematic modifications are needed when upgrading from the commercial to automotive-grade variant.
What is the thermal resistance specification for SMA5J10AHE3_A/H?
SMA5J10AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured under standard conditions (25 °C ambient, 0.2" × 0.2" copper pads per terminal). These values guide thermal design for sustained surge duty cycles and ambient temperature derating.
