Product details
Overview
SMA5J36AHE3/61 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 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 58.1 V clamping voltage (VC) at 8.6 A peak pulse current, and 500 W peak pulse power (10/1000 µs). It is AEC-Q101 qualified and used to protect automotive sensor interfaces and industrial power rails.
For engineers reviewing the SMA5J36AHE3/61 datasheet, SMA5J36AHE3/61 pinout, SMA5J36AHE3/61 application, or SMA5J36AHE3/61 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, 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.
The device is rated for 150 °C maximum junction temperature and exhibits 80 °C/W junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads. Its unidirectional polarity-marked by cathode band-is essential for correct placement in DC-biased protection paths such as automotive 12 V supply rails and CAN transceiver I/O lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR (min/max) | 40.0 V / 44.2 V - Breakdown occurs within this range at 1 mA test current; sets minimum clamping threshold. |
| VC @ IPPM | 58.1 V at 8.6 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling capability; defines survivability against standardized lightning/surge events. |
| IFSM | 40 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports protection during load dump conditions. |
| TJ max. | 150 °C - Maximum junction temperature; constrains PCB layout and thermal pad design for reliability. |
| RθJA | 80 °C/W - Thermal resistance junction-to-ambient on recommended pad layout; informs thermal derating above 25 °C. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by black band; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential rail; must be routed with low-inductance path for effective clamping. |
| Cathode | Reverse-biased terminal / high-side connection | Marked with band; connects to protected line (e.g., 12 V supply or signal trace) to shunt surges to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for under-hood and ADAS applications. |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<1.0 µA) over lifetime and temperature extremes. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns. |
| Low incremental surge resistance | Enables tighter clamping (VC = 58.1 V) versus competing 500 W TVS devices, reducing stress on protected MOSFETs or transceivers. |
Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36A-E3/61 | No AEC-Q101 qualification; commercial grade only; identical electrical specs and package. | Not suitable for automotive production; acceptable for industrial prototypes or non-safety-critical consumer designs. | Select SMA5J36AHE3/61 when automotive qualification, extended temperature validation, or long-term reliability reporting is required. |
| SMC5J36AHE3/61 | Same VWM/VC but in larger SMC (DO-214AB) package; higher IPPM (12.3 A) and lower RθJA (50 °C/W). | Better thermal performance and surge margin; requires larger PCB footprint and different pad layout. | Choose SMC5J36AHE3/61 where board space permits and higher single-pulse robustness (>500 W) is needed. |
Compared with SMA5J36A-E3/61, the SMA5J36AHE3/61 adds AEC-Q101 compliance for automotive use without electrical trade-offs; compared with SMC5J36AHE3/61, it trades thermal margin and peak current capacity for compact SMA footprint-critical for space-constrained sensor modules.

FAQ
What is the clamping voltage of the SMA5J36AHE3/61 under a 10/1000 µs surge?
The SMA5J36AHE3/61 clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 8.6 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with the device mounted on 5.0 mm × 5.0 mm copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the SMA5J36AHE3/61 suitable for automotive applications?
Yes, the SMA5J36AHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use, as confirmed by its "HE3" suffix and documentation in Vishay's 88875 datasheet. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to ensure reliability in engine control units, body control modules, and ADAS sensor interfaces.
What does the "HE3" suffix mean in SMA5J36AHE3/61?
The "HE3" suffix in SMA5J36AHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this automotive-grade variant from commercial versions (e.g., "E3") and halogen-free variants (e.g., "HM3"), confirming compliance with both environmental standards and automotive reliability requirements.
How does the SMA5J36AHE3/61 differ from bidirectional TVS diodes like SMA5J36CA?
The SMA5J36AHE3/61 is unidirectional and features polarity marking (cathode band), enabling asymmetric protection in DC-biased circuits. In contrast, SMA5J36CA is bidirectional with no polarity marking and symmetrical clamping in both directions-making it suitable for AC lines or differential signals but unsuitable for single-polarity rail protection without additional circuitry.
What is the maximum junction temperature rating for the SMA5J36AHE3/61?
The SMA5J36AHE3/61 has a maximum junction temperature (TJ) rating of +150 °C, as specified in Vishay's 88875 datasheet. This rating governs thermal design margins and requires appropriate PCB copper area and ambient temperature control to maintain reliability during repeated surge events or continuous high-power dissipation.
