Product details
Overview
SMA5J10AHE3/61 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) at 1 mA, 17.0 V clamping voltage (VC) at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMA5J10AHE3/61 datasheet, SMA5J10AHE3/61 pinout, SMA5J10AHE3/61 application, or SMA5J10AHE3/61 equivalent, key selection criteria include clamping performance under 29.4 A surge, AEC-Q101 qualification status, unidirectional polarity marking, thermal resistance (RθJA = 80 °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-clamped shunt protector: when reverse voltage exceeds VBR (11.1–12.3 V), it avalanches to limit transient energy across protected circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response (<1 ns), while low incremental surge resistance enables effective suppression of inductive switching spikes and ESD events.
The device is rated for TJ = –55 °C to +150 °C, meets MSL Level 1 (260 °C reflow peak), and supports unidirectional surge handling up to 40 A IFSM (8.3 ms half-sine). AEC-Q101 qualification (denoted by HE3 suffix) confirms suitability for automotive electronics requiring robust reliability under temperature cycling and humidity exposure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during transients |
| VC @ IPPM | 17.0 V at 29.4 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs |
| PPPM | 500 W - peak pulse power handling capability; defines survivability against standardized lightning/surge waveforms |
| ID @ VWM | ≤1.0 µA - reverse leakage at stand-off voltage; critical for low-power sensor and battery-backed circuits |
| TJ max. | +150 °C - maximum junction temperature; sets thermal derating limits for sustained surge duty cycles |

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 | No AEC-Q101 qualification; commercial grade only; identical electrical specs and package | Not suitable for automotive production; acceptable for consumer/industrial prototypes | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMC5J10AHE3/61 | Larger SMC (DO-214AB) package; same VWM/VBR/VC but higher thermal mass (RθJA = 40 °C/W vs. 80 °C/W) | Better thermal performance for high-duty-cycle surges; requires larger PCB footprint | Select when surge repetition rate exceeds SMA5J10AHE3/61 thermal limits or layout allows larger case |
Compared with SMA5J10AHE3/61, the E3/61 variant lacks automotive qualification but offers identical surge ratings at lower cost, while the SMC5J10AHE3/61 provides superior thermal dissipation in space-tolerant designs - enabling longer surge hold times or higher ambient temperature operation.

FAQ
What is the clamping voltage of the SMA5J10AHE3/61 under a 10/1000 µs surge?
The SMA5J10AHE3/61 has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current of 29.4 A using the standard 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA5J10AHE3/61 maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is SMA5J10AHE3/61 qualified for automotive applications?
Yes, the SMA5J10AHE3/61 is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST), ensuring reliability in automotive environments such as engine compartments and infotainment systems. The SMA5J10AHE3/61 is explicitly designated for automotive use in Vishay's documentation and meets all requirements for Grade 1 (–40 °C to +125 °C ambient) operation.
What does the "/61" suffix indicate in SMA5J10AHE3/61?
The "/61" suffix in SMA5J10AHE3/61 specifies the preferred packaging format: 7-inch diameter plastic tape and reel containing 1800 units. This is a standard logistics identifier defined in Vishay's ordering information table and does not affect electrical or thermal specifications. The SMA5J10AHE3/61 is supplied in this format with RoHS-compliant, AEC-Q101-qualified construction and matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
How does the thermal resistance of SMA5J10AHE3/61 impact PCB layout?
The SMA5J10AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures during repeated surges, PCB layout must provide adequate copper area and thermal vias - reducing RθJA below 80 °C/W lowers thermal stress and extends device lifetime. The SMA5J10AHE3/61's RθJL of 25 °C/W further emphasizes the importance of direct thermal connection from leads to inner-layer ground planes.
Can SMA5J10AHE3/61 be used in bidirectional configurations?
No, SMA5J10AHE3/61 is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional operation requires the "CA" variant (e.g., SMA5J10CA), which has symmetrical breakdown characteristics in both polarities. Using SMA5J10AHE3/61 in reverse-biased AC signal paths would result in forward conduction and failure; the SMA5J10AHE3/61 must be oriented with cathode toward the protected line and anode to ground.
