Product details
Overview
SMA6J10AHM3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR at IT = 1 mA), 15.7 V maximum clamping voltage (VC at IPP = 38.2 A, 10/1000 μs), 600 W peak pulse power (10/1000 μs), and 150 °C max junction temperature - used for protecting MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMA6J10AHM3/5A datasheet, SMA6J10AHM3/5A pinout, SMA6J10AHM3/5A application, or SMA6J10AHM3/5A equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VDD, unidirectional polarity compatibility with DC-biased lines, thermal resistance (RθJA = 120 °C/W), and M3 halogen-free RoHS compliance for high-reliability PCB assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (10 V), avalanches sharply at VBR (min 11.1 V), and limits surge voltage to ≤15.7 V at 38.2 A (10/1000 μs). Its low dynamic resistance (RD = 0.089 Ω) ensures tight clamping under fast transients.
Designed for surface-mount automation on standard PCBs, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), uses matte tin-plated leads, and features a cathode band marking. The SMA package provides 5.0 mm × 5.0 mm copper pad thermal performance per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; sets upper limit for safe DC bias on protected line. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Confirmed avalanche onset range; determines minimum overvoltage threshold for clamping activation. |
| VC at IPP | 15.7 V at 38.2 A (10/1000 μs) - Measured clamping voltage during standardized surge; must stay below protected device's absolute max rating. |
| PPPM (10/1000 μs) | 600 W - Peak power handling for long-duration transients (e.g., inductive kickback); defines energy absorption capability. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on recommended 5.0 mm × 5.0 mm pads; used to calculate ΔTJ under steady-state PD = 4 W. |
| Polarity | Unidirectional - Blocks reverse current only; requires correct orientation relative to DC bias; not suitable for AC or bidirectional signal lines. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with cathode band; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, cathode denoted by color band. Mounting requires 5.0 mm × 5.0 mm copper pads per terminal per datasheet Fig. 2 derating guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to circuit ground or lowest potential node; carries surge current to reference plane during clamping. |
| Cathode | High-side connection point | Connected to protected line (e.g., MOSFET drain or IC supply rail); voltage referenced to anode during transient conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping voltage control | VC = 15.7 V at 38.2 A ensures <1.6× VWM margin - sufficient headroom to protect 12 V logic rails and 20 V MOSFETs without overstress. |
| Halogen-free construction | M3 suffix confirms halogen-free molding compound and terminations - meets IPC-4101D/102 and automotive ELV requirements. |
| Automated placement support | Low-profile SMA package with J-STD-020 MSL Level 1 rating enables reliable high-speed SMT assembly without moisture sensitivity concerns. |
| Thermal robustness | RθJL = 25 °C/W (junction-to-lead) supports localized heat extraction through PCB traces, critical for repeated surge events in power converters. |
Applications
| Industrial Motor Drives | DC-DC Converter Outputs |
|---|---|
Use Scenario: Protecting IGBT gate drivers and bootstrap FETs from flyback voltage spikes during PWM switching in 24 V/48 V motor controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10A-E3/5A | Same electrical specs but RoHS-compliant E3 suffix (not halogen-free); RθJA identical; same SMA package and marking code 6AX. | No halogen-free requirement; acceptable for commercial-grade industrial equipment without automotive or green procurement mandates. | Select when halogen-free certification is not required and cost optimization is prioritized over material compliance. |
| SMCJ10A-M3 | Higher 1500 W PPPM (10/1000 μs); larger SMC (DO-214AB) package; VC = 17.0 V at 87.2 A; same VWM/VBR range and unidirectional polarity. | Required for >1 kV surge immunity (e.g., AC mains interfaces or outdoor telecom); needs larger PCB footprint and higher thermal mass. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and 600 W is insufficient. |
Compared with SMA6J10A-E3/5A, the SMA6J10AHM3/5A adds halogen-free assurance without sacrificing clamping performance; versus SMCJ10A-M3, it trades 2.5× peak power for 30 % smaller board area and lower thermal inertia - optimal for space-constrained 12 V embedded power rails.

FAQ
What is the maximum clamping voltage of the SMA6J10AHM3/5A under a 10/1000 μs surge?
The SMA6J10AHM3/5A has a maximum clamping voltage (VC) of 15.7 V when subjected to a 10/1000 μs waveform at 38.2 A peak pulse current, as specified in the Vishay datasheet Document Number 89460. This value is measured at TA = 25 °C on standard 5.0 mm × 5.0 mm copper pads. The SMA6J10AHM3/5A maintains this clamping performance across its operating temperature range, making it suitable for protecting 12 V systems where margin above VWM is critical.
Does the SMA6J10AHM3/5A support automated SMT assembly?
Yes, the SMA6J10AHM3/5A supports automated surface-mount assembly: it is packaged in a low-profile SMA (DO-214AC) case rated MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the M3 suffix confirms JESD 201 Class 2 whisker resistance. The SMA6J10AHM3/5A is supplied on 13" tape-and-reel (5A packaging code) for high-volume pick-and-place integration.
How does the M3 suffix affect the environmental compliance of the SMA6J10AHM3/5A?
The M3 suffix on SMA6J10AHM3/5A indicates halogen-free, RoHS-compliant construction meeting IPC-4101D/102 and automotive ELV standards, with no brominated flame retardants or chlorine-based additives. This differs from the E3 variant (lead-free RoHS only) and ensures compliance in green procurement programs. The SMA6J10AHM3/5A's M3 qualification is verified per Vishay's material categorization document www.vishay.com/doc?99912, and applies to both molding compound and terminations.
Can the SMA6J10AHM3/5A be used on bidirectional signal lines?
No, the SMA6J10AHM3/5A is a unidirectional TVS diode and must be used only on DC-biased or positively referenced lines. Its cathode band marks the high-side terminal, and it conducts only when the cathode is ~11.1 V above the anode. It cannot suppress negative-going transients on AC or floating signals. For bidirectional protection, a symmetric pair or dedicated bidirectional TVS such as SMBJ10A would be required - the SMA6J10AHM3/5A is unsuitable for USB, RS-485, or other differential or AC-coupled interfaces.
What is the thermal resistance and power derating behavior of the SMA6J10AHM3/5A?
The SMA6J10AHM3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal, and a junction-to-lead resistance (RθJL) of 25 °C/W. Its steady-state power dissipation is rated at 4.0 W at TA = 50 °C, derating linearly to zero at TJ = 150 °C. Per Figure 2 in datasheet 89460, power capability drops to ~65 % at TA = 100 °C - critical for enclosed industrial enclosures where ambient exceeds 70 °C. The SMA6J10AHM3/5A's thermal profile is validated for continuous operation under these conditions.
