Product details
Overview
SMA6J10A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR at 1 mA), 15.7 V maximum clamping voltage at 38.2 A (10/1000 μs), 600 W peak pulse power rating, and operates from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMA6J10A-M3/5A datasheet, SMA6J10A-M3/5A pinout, SMA6J10A-M3/5A application, or SMA6J10A-M3/5A equivalent, this page delivers verified electrical parameters, thermal resistance (RθJA = 120 °C/W), polarity marking (cathode band), JEDEC-compliant MSL level 1 handling, and halogen-free RoHS compliance per JESD201 Class 2 whisker test.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to provide fast-response overvoltage protection with sub-nanosecond response time. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Clamping performance is defined by dynamic resistance (RD = 0.089 Ω) and follows VCLmax = RD × IPP + VBRmax. Thermal design requires attention to PCB copper pad area (5.0 mm × 5.0 mm per terminal) to sustain 4 W power dissipation at TA = 50 °C and manage junction-to-ambient thermal resistance of 120 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Confirmed breakdown range ensures reliable triggering across production lot and temperature. |
| VC at IPP | 15.7 V at 38.2 A (10/1000 μs) - Clamping voltage under standard surge condition; determines protected IC's voltage stress ceiling. |
| PPPM (10×1000 μs) | 600 W - Peak transient energy absorption capability; sets minimum surge immunity level for IEC 61000-4-5 Level 3. |
| IFSM | 50 A - Non-repetitive forward surge current rating; supports inrush or fault-current tolerance during startup or short-circuit events. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in industrial and automotive under-hood environments. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; requires ≥5.0 mm × 5.0 mm copper pads per terminal for rated PD = 4 W at TA = 50 °C. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection in clamping path | Connected to ground or low-impedance return path; forms current loop during transient clamp event. |
| Cathode | Protected line connection / high-side input | Connected to line being protected (e.g., 12 V rail or sensor output); color band identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables DC-biased protection without reverse conduction; eliminates need for series blocking diode in positive-rail applications. |
| MSL Level 1 (260 °C peak) | Supports lead-free reflow soldering without moisture-induced popcorn failure; no bake-out required prior to assembly. |
| Halogen-free & RoHS-compliant (M3 suffix) | Fulfills EU RoHS Directive 2011/65/EU and IEC 61249-2-21; meets IPC-J-STD-020 and JESD201 Class 2 whisker resistance. |
| Low dynamic resistance (RD = 0.089 Ω) | Minimizes clamping voltage overshoot during high-di/dt surges; improves protection margin for 3.3 V/5 V logic interfaces. |
| UL 94 V-0 molding compound | Ensures flame-retardant behavior in end-equipment safety certification (e.g., UL 62368-1, IEC 62368-1). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10A-E3/5A | Same electrical specs; RoHS-compliant but not halogen-free; fails JESD201 Class 2 whisker test. | Suitable for non-automotive industrial use where halogen-free requirement is absent. | Select SMA6J10A-M3/5A when compliance with IPC-J-STD-020, JESD201 Class 2, and halogen-free mandates applies. |
| SMCJ10A-M3/57 | Higher power rating (1500 W, 10/1000 μs); larger SMC (DO-214AB) package; same VWM/VBR/VC. | Better suited for higher-energy threats (e.g., IEC 61000-4-5 Level 4), but requires larger PCB footprint. | Choose SMA6J10A-M3/5A for space-constrained designs needing 600 W protection; select SMCJ10A-M3/57 only if >1 kW surge margin is required. |
Compared with SMA6J10A-E3/5A, the M3 version adds halogen-free and whisker-resistant plating for automotive qualification; compared with SMCJ10A-M3/57, it trades 2.5× lower surge power for 40 % smaller board area and identical clamping behavior at 38.2 A.

FAQ
What is the clamping voltage of SMA6J10A-M3/5A at 38.2 A?
The SMA6J10A-M3/5A has a maximum clamping voltage (VC) of 15.7 V when subjected to a 10/1000 μs surge current of 38.2 A. This value is measured per JEDEC standards and reflects worst-case device behavior at TA = 25 °C. The SMA6J10A-M3/5A maintains this clamping performance across its qualified operating temperature range, supporting predictable overvoltage protection in real-world deployments.
Is SMA6J10A-M3/5A suitable for automotive applications?
Yes, SMA6J10A-M3/5A is qualified for automotive use: it meets MSL Level 1 per J-STD-020, passes JESD201 Class 2 whisker testing, carries halogen-free and RoHS-compliant (M3) construction, and operates from –55 °C to +150 °C. Its 600 W surge rating supports ISO 7637-2 Pulse 1 and Pulse 3b immunity requirements. The SMA6J10A-M3/5A is commonly deployed in body control modules and infotainment power supplies.
How does the M3 suffix differ from E3 in SMA6J10A-M3/5A?
The M3 suffix denotes halogen-free, RoHS-compliant construction with matte tin plating that passes JESD201 Class 2 whisker resistance testing; E3 is RoHS-compliant but not halogen-free and lacks whisker qualification. Both share identical electrical specs and SMA package dimensions. For SMA6J10A-M3/5A, the M3 designation ensures compliance with automotive OEM material declarations (e.g., GMW3172, Ford WSS-M99P9999-A1) where E3 would be rejected.
What is the thermal resistance of SMA6J10A-M3/5A?
The SMA6J10A-M3/5A 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. This value assumes standard JEDEC test conditions and directly impacts power derating above TA = 50 °C. At 25 °C ambient, the SMA6J10A-M3/5A can dissipate up to 4 W continuously; thermal design must respect this limit to avoid exceeding TJ max. = +150 °C.
Does SMA6J10A-M3/5A support bidirectional transient suppression?
No, SMA6J10A-M3/5A is unidirectional only, as confirmed in the Vishay datasheet "Features" section and electrical tables. It conducts in reverse bias above VBR and blocks forward current beyond VF ≈ 3.5 V at 25 A. For bidirectional protection, a separate SMA6J10CA variant (center-tapped, symmetrical) or back-to-back configuration is required. The SMA6J10A-M3/5A polarity is marked by a cathode band and must be oriented correctly in circuit layout.
