Product details
Overview
SMA5J10HE3/61 from Vishay General Semiconductor is a unidirectional 500 W Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, with 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), and 17.0 V clamping voltage (VC) at 29.4 A peak pulse current (IPPM). It provides robust ESD and surge protection for automotive power rails and I/O lines.
For engineers reviewing the SMA5J10HE3/61 datasheet, SMA5J10HE3/61 pinout, SMA5J10HE3/61 application, or SMA5J10HE3/61 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in series with power or signal lines, conducting only when reverse voltage exceeds VBR to limit transient energy. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response (<1 ns), while the DO-214AC package supports high thermal dissipation (RθJA = 80 °C/W).
Designed for single-polarity protection, it delivers 500 W peak pulse power (10/1000 μs waveform) with 17.0 V clamping at rated IPPM, enabling reliable suppression of inductive switching spikes and lightning-induced surges in automotive ECUs and industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 17.0 V - Clamped voltage across device at 29.4 A peak pulse, limiting downstream stress |
| PPPM | 500 W - Peak transient power it can absorb without failure (10/1000 μs waveform) |
| ID @ VWM | <1.0 μA - Reverse leakage at 10 V ensures minimal standby power loss and signal integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10A-E3/61 | Commercial grade (non-AEC-Q101); identical electrical specs and DO-214AC package | Lacks automotive qualification; suitable for consumer/industrial use where AEC compliance is not required | Select when cost sensitivity outweighs automotive reliability requirements |
| SMC5J10AHE3/61 | Same electrical specs but in larger DO-214AB (SMC) package; higher thermal mass and RθJA = 35 °C/W | Better power derating above 75 °C ambient; requires larger PCB footprint | Choose for high-temperature environments (>105 °C) where thermal headroom is critical |

FAQ
What is the maximum clamping voltage of the SMA5J10HE3/61 at its rated peak pulse current?
The SMA5J10HE3/61 has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 29.4 A under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C on minimum recommended copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA5J10HE3/61 maintains this clamping performance across its qualified operating temperature range.
Is the SMA5J10HE3/61 suitable for automotive applications?
Yes, the SMA5J10HE3/61 is AEC-Q101 qualified and explicitly designed for automotive use. Its qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The SMA5J10HE3/61 is commonly deployed in engine control modules, body control units, and ADAS sensor power supplies where robust transient immunity is required per ISO 7637-2 and ISO 16750-2 standards.
What does the "HE3" suffix indicate in SMA5J10HE3/61?
The "HE3" suffix in SMA5J10HE3/61 denotes two key attributes: "H" indicates AEC-Q101 qualification, and "E3" specifies RoHS-compliant, commercial-grade construction with matte tin plating meeting JESD 201 Class 2 whisker resistance. This distinguishes it from "E3"-only variants (e.g., SMA5J10A-E3/61), which lack automotive qualification. The SMA5J10HE3/61 thus combines environmental compliance with automotive reliability assurance.
How does the thermal resistance of the SMA5J10HE3/61 affect its surge handling capability?
The SMA5J10HE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" copper pads. This value directly limits sustained power dissipation and influences derating above 25 °C ambient: for example, at 85 °C ambient, its peak pulse power must be reduced by ~40 % per Vishay's Fig. 2 derating curve. Proper PCB copper area is essential to maintain the SMA5J10HE3/61 within its 150 °C junction temperature limit during repeated surges.
Can the SMA5J10HE3/61 be used in bi-directional configurations?
No, the SMA5J10HE3/61 is a unidirectional TVS diode, as indicated by the absence of "CA" in its part number. Bi-directional variants (e.g., SMA5J10CAHE3/61) are separately specified with symmetrical breakdown in both polarities. Using the SMA5J10HE3/61 in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection, select the CA-suffixed version or pair unidirectional devices back-to-back-though the SMA5J10HE3/61 itself is strictly for DC or single-polarity transient suppression.
