Product details
Overview
SMA5J6.0AHM3/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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 10.3 V clamping voltage (VC) at 48.5 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J6.0AHM3/H datasheet, SMA5J6.0AHM3/H pinout, SMA5J6.0AHM3/H application, or SMA5J6.0AHM3/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (via HM3 suffix), halogen-free RoHS compliance, 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 high-impedance below VWM = 6.0 V and rapidly transitions to low-impedance conduction above VBR (min 6.67 V) to limit transient overvoltages. Its glass-passivated junction ensures stable breakdown behavior and long-term reliability under repetitive surge stress.
Designed for 10/1000 µs surge waveforms, it delivers 48.5 A peak pulse current (IPPM) while clamping to ≤10.3 V, enabling robust protection of 5 V–6 V rail systems. Thermal resistance is RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), supporting operation up to TJ = +150 °C with derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 800 μA; sets upper limit for protected circuit's nominal rail. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamped voltage during 500 W surge; determines maximum stress imposed on downstream components. |
| PPPM | 500 W - Peak pulse power handling per 10/1000 µs waveform; defines single-event surge energy absorption capability. |
| IFSM | 40 A - Non-repetitive forward surge current (8.3 ms half-sine); supports inrush or fault-current tolerance in power path applications. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-side reference; completes clamping loop during transient events. |
| Cathode | Reverse-biased terminal / protected line connection | Connected to the line being protected (e.g., 6 V supply rail); blocks normal operation but conducts during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant construction | Meets environmental compliance requirements for automotive and industrial end equipment without compromising surge performance. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for engine control and ADAS modules. |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR = ~3.6 V), reducing voltage overshoot and improving system-level ESD/surge margin. |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT assembly without moisture sensitivity concerns or pre-bake requirements. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0AHE3/H | Same electrical specs, RoHS-compliant but not halogen-free; AEC-Q101 qualified via HE3 suffix. | Lacks halogen-free certification; acceptable where material compliance is less restrictive than automotive OEM requirements. | Select SMA5J6.0AHE3/H when halogen-free content is not mandated but AEC-Q101 qualification and RoHS remain required. |
| SMA6J6.0A-M3 | Same VWM/VBR/VC, but rated for 600 W PPPM; larger thermal mass; DO-214AC package identical. | Higher surge margin allows extended lifetime in high-cycle industrial environments; slightly higher cost and footprint. | Choose SMA6J6.0A-M3 when system-level surge testing exceeds 500 W or long-term reliability under repetitive stress is critical. |
Compared with SMA5J6.0AHM3/H, SMA5J6.0AHE3/H offers identical surge performance with non-halogen-free materials, while SMA6J6.0A-M3 provides 20 % higher peak power handling in the same footprint - enabling design flexibility for varying reliability and compliance tiers.

FAQ
What is the clamping voltage of the SMA5J6.0AHM3/H under maximum surge conditions?
The SMA5J6.0AHM3/H clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured at the device terminals under standardized test conditions with 0.2" × 0.2" copper pads, ensuring predictable overvoltage limiting for downstream 6 V-rated components in the SMA5J6.0AHM3/H protection circuit.
Is the SMA5J6.0AHM3/H suitable for automotive applications?
Yes, the SMA5J6.0AHM3/H is AEC-Q101 qualified (denoted by the HM3 suffix), halogen-free, and RoHS-compliant - meeting stringent automotive reliability requirements. It is validated for use in engine control units, body electronics, and ADAS subsystems where transient immunity and long-term stability under thermal cycling are essential for the SMA5J6.0AHM3/H deployment.
What does the "HM3" suffix indicate in SMA5J6.0AHM3/H?
The "HM3" suffix in SMA5J6.0AHM3/H specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade (E3/M3) or non-halogen-free automotive (HE3) versions, confirming full compliance with automotive material and reliability standards for the SMA5J6.0AHM3/H part.
How does the SMA5J6.0AHM3/H compare to bidirectional TVS diodes like SMA5J6.0CA?
The SMA5J6.0AHM3/H is unidirectional and intended for DC rail protection with defined polarity (cathode marked), whereas SMA5J6.0CA is bidirectional and symmetrical. The SMA5J6.0AHM3/H offers lower leakage (<800 μA at 6.0 V) and higher IFSM (40 A), making it preferable for polarized power-line applications where reverse conduction must be blocked.
What PCB layout considerations apply to the SMA5J6.0AHM3/H?
For optimal thermal and surge performance, the SMA5J6.0AHM3/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's recommended pad layout. Short, wide traces to ground minimize inductance, preserving sub-nanosecond response; avoid thermal relief on cathode/anode pads to maintain RθJL = 25 °C/W.
