Product details
Overview
SMA5J6.0AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 48.5 A, and operates from −55 °C to +150 °C junction temperature.
For engineers reviewing the SMA5J6.0AHM3/I datasheet, SMA5J6.0AHM3/I pinout, SMA5J6.0AHM3/I application, or SMA5J6.0AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 80 °C/W), polarity marking convention, and real-world use cases in automotive sensor protection and industrial power supply input stages.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced transients. Its low incremental surge resistance and stable clamping behavior under repetitive 10/1000 µs surges enable reliable protection of downstream MOSFETs and ICs without sacrificing system efficiency.
The SMA5J6.0AHM3/I is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive applications. It mounts on 5.0 mm × 5.0 mm copper pads per terminal and meets JESD201 Class 2 whisker resistance with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin for safe operation. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamping voltage during 500 W surge defines maximum stress imposed on protected circuitry. |
| PPPM | 500 W (10/1000 µs waveform) - Sustains high-energy transients common in automotive load-dump and industrial switching events. |
| IFSM | 40 A (8.3 ms half-sine) - Supports robust handling of non-repetitive forward surge currents in unidirectional configurations. |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and thermally constrained industrial enclosures. |
| RθJA | 80 °C/W - Thermal resistance value guides PCB pad sizing and layout decisions to maintain junction temperature within limits. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with cathode band marking on unidirectional types. Molding compound complies with UL 94 V-0; terminals are matte tin plated and solderable per J-STD-002.

Applications
| Automotive Sensor Protection | Industrial Power Input Stage |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from ISO 7637-2 pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor supply line and chassis ground to clamp negative-going spikes and positive load-dump surges. Use Value: Limits voltage seen by sensor IC to ≤10.3 V during 48.5 A surge, preventing latch-up or permanent damage in AEC-Q100 grade components. |
Use Scenario: Safeguarding 6 V auxiliary power rails in PLC modules and motor drives against inductive kickback and AC line coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input derived from rectified 8.5 V AC or buck-regulated source. Use Value: Absorbs 500 W transient energy without degradation, maintaining system uptime where fuse-only protection would fail. |
| Consumer USB Power Delivery | Telecom Line Interface |
Use Scenario: Secondary surge suppression on 5 V–6 V USB-C PD sink paths after primary front-end filtering. IC Role / Device Role / Timing Role: Fast-response clamping device placed adjacent to USB controller VBUS pin to suppress ESD and conducted noise. Use Value: Sub-10 ns response time and 10.3 V clamping prevent false resets or brownouts in USB enumeration logic during ±8 kV contact discharge. |
Use Scenario: DC bias rail protection in PoE-powered Ethernet PHY interfaces operating at 6 V auxiliary supply. IC Role / Device Role / Timing Role: Standoff-rated TVS on isolated DC-DC converter output feeding Ethernet magnetics bias winding. Use Value: Withstands repeated 10/1000 µs surges up to 48.5 A while maintaining <1 µA leakage at 6.0 V, preserving signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0A-M3/61 | No AEC-Q101 qualification; same electrical specs and SMA package; M3 suffix denotes halogen-free, RoHS-compliant commercial grade. | Suitable for non-automotive industrial or consumer applications where automotive qualification is not mandated. | Select when cost sensitivity outweighs automotive reliability validation needs and lifecycle assurance is less critical. |
| SMA5J6.0AHE3_A/I | AEC-Q101 qualified (HE3 suffix), RoHS-compliant but not halogen-free; otherwise identical VWM, VBR, PPPM, and package. | Preferred for legacy automotive programs requiring AEC-Q101 but not halogen-free material compliance. | Choose when existing design documentation references HE3 and halogen content is not restricted by OEM specification. |
Compared with SMA5J6.0AHM3/I, the M3/61 variant offers identical surge performance at lower qualification cost, while the HE3_A/I provides AEC-Q101 compliance without halogen-free assurance-making HM3/I the only option satisfying both automotive qualification and halogen-free mandates simultaneously.

FAQ
What is the clamping voltage of the SMA5J6.0AHM3/I under maximum surge conditions?
The SMA5J6.0AHM3/I clamps to 10.3 V at its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured and guaranteed per Vishay's datasheet, ensuring protected circuits experience no more than 10.3 V during worst-case transient events. The SMA5J6.0AHM3/I maintains this clamping performance across its full operating temperature range.
Is the SMA5J6.0AHM3/I suitable for automotive applications?
Yes, the SMA5J6.0AHM3/I is AEC-Q101 qualified and specifically designated for automotive use via the HM3 suffix. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive reliability standards. The SMA5J6.0AHM3/I is commonly deployed in engine control units, body electronics, and ADAS sensor modules.
What does the "HM3" suffix indicate in SMA5J6.0AHM3/I?
The "HM3" suffix in SMA5J6.0AHM3/I identifies it as halogen-free, RoHS-compliant, and AEC-Q101 qualified. The "H" denotes AEC-Q101 qualification, "M3" confirms halogen-free and RoHS compliance, and the "/I" specifies 13-inch tape-and-reel packaging with 7500 units per reel. This distinguishes it from commercial-grade (M3) or AEC-Q101-only (HE3) variants.
How does the SMA5J6.0AHM3/I compare to bidirectional TVS diodes like SMA5J6.0CA?
The SMA5J6.0AHM3/I is unidirectional and intended for DC line protection with defined polarity, whereas SMA5J6.0CA is bidirectional and used in AC-coupled or symmetric signal paths. The SMA5J6.0AHM3/I has a forward voltage drop (~3.5 V at 25 A), while SMA5J6.0CA exhibits symmetrical clamping in both directions and no forward conduction path. They are not interchangeable without circuit redesign.
What PCB layout guidance applies to the SMA5J6.0AHM3/I for optimal thermal performance?
For optimal thermal performance, mount the SMA5J6.0AHM3/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Use thermal vias under pads if board layer count permits, and avoid narrow traces between the SMA5J6.0AHM3/I and ground plane. This layout achieves the rated RθJA of 80 °C/W and prevents derating under sustained surge duty cycles.
