Product details
Overview
SMA5J6.0A-M3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 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 (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMA5J6.0A-M3/61 datasheet, SMA5J6.0A-M3/61 pinout, SMA5J6.0A-M3/61 application, or SMA5J6.0A-M3/61 equivalent, key selection criteria include verified clamping performance under 500 W surge, unidirectional polarity with cathode band marking, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by transient overvoltage events exceeding its VWM of 6.0 V. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<800 μA at VWM), while its low incremental surge resistance enables rapid energy diversion during 10/1000 μs surges.
The SMA5J6.0A-M3/61 is rated for TJ = −55 °C to +150 °C operation, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and exhibits typical thermal resistance RθJA = 80 °C/W - requiring careful PCB copper pad design to sustain repetitive surge duty cycles without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for protected circuitry. |
| VBR (min/max) | 6.67 V / 7.37 V at IT = 10 mA - guaranteed breakdown threshold range; ensures predictable turn-on across temperature and unit variation. |
| 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 with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <800 μA - reverse leakage at stand-off voltage; low enough to avoid loading sensitive 6 V logic or sensor bias networks. |
| Package | SMA (DO-214AC) - surface-mount outline with 0.208" × 0.157" footprint; compatible with standard pick-and-place and reflow profiles. |
| Polarity | Unidirectional - cathode indicated by band; blocks forward conduction, clamps only reverse transients - suited for DC supply line protection. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, M3 suffix denotes halogen-free and RoHS-compliant construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; forms return path during clamping event. |
| Cathode (banded end) | High-side surge input terminal | Connected to protected line (e.g., 6 V rail); conducts when transient exceeds VBR, shunting current to anode. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMA package | Enables high-density layout on space-constrained boards while maintaining 500 W surge capability - no height penalty vs. larger DO-214AB packages. |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime - critical for automotive ECUs requiring 15-year reliability. |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns - eliminates baking requirement and reduces manufacturing cost. |
| AEC-Q101 qualification option | HE3/HM3 variants available; SMA5J6.0A-M3/61 itself is commercial-grade but shares identical die and construction - simplifies qualification migration paths. |
| Automated placement optimized | Standard tape-and-reel packaging (61 code = 1800 units per 7" reel) and lead coplanarity <0.006" ensure >99.9% placement yield in high-speed SMT lines. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input 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 |
|---|---|---|---|
| SMA5J6.0A-E3/61 | Same electrical specs and package; RoHS-compliant but not halogen-free (E3 vs. M3). | Approved for commercial-grade consumer electronics where halogen content is unrestricted. | Select E3 for cost-sensitive non-automotive designs; M3 required for EU EcoDesign or Japanese JIS C 0950 compliance. |
| SMA6J6.0A-M3/61 | Higher PPPM (600 W vs. 500 W); same VWM/VBR/VC but larger junction area increases thermal mass. | Better suited for applications with frequent or higher-energy surges (e.g., outdoor industrial gateways). | Choose SMA6J6.0A-M3/61 if design requires margin beyond IEC 61000-4-5 Level 4; verify PCB pad thermal relief matches increased RθJA. |
Compared with SMA5J6.0A-E3/61, the M3 variant adds halogen-free compliance without sacrificing surge rating; versus SMA6J6.0A-M3/61, it trades 100 W peak power for tighter board space and lower thermal resistance - making SMA5J6.0A-M3/61 optimal for cost- and size-constrained 6 V rail protection where 500 W is sufficient.

FAQ
What is the maximum clamping voltage of the SMA5J6.0A-M3/61 under a 500 W surge?
The SMA5J6.0A-M3/61 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 48.5 A - corresponding to a 10/1000 μs waveform delivering 500 W. This value is measured at TA = 25 °C with devices mounted on 0.2" × 0.2" copper pads per JEDEC standards. The SMA5J6.0A-M3/61 maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C, with minor derating above 25 °C per Figure 2 in the datasheet.
Is the SMA5J6.0A-M3/61 suitable for automotive applications?
The SMA5J6.0A-M3/61 is qualified to commercial grade specifications and is halogen-free and RoHS-compliant, but it is not AEC-Q101 qualified. For automotive use, Vishay offers the SMA5J6.0AHM3_A/H variant - identical in all electrical and mechanical characteristics except for AEC-Q101 qualification and packaging revision coding. The SMA5J6.0A-M3/61 may be used in non-safety-critical automotive subsystems where qualification is not mandated, but full AEC-Q101 compliance requires the HM3_X suffix version.
How does the M3 suffix differ from E3 in SMA5J6.0A-M3/61?
The M3 suffix in SMA5J6.0A-M3/61 indicates halogen-free, RoHS-compliant construction, whereas E3 denotes RoHS-compliant but not halogen-free materials. Both share identical electrical parameters, package dimensions, thermal performance, and reliability testing. The M3 variant meets stricter environmental regulations such as JEITA EG-8001 and Japanese JIS C 0950, making it mandatory for products sold in markets enforcing halogen bans. The SMA5J6.0A-M3/61 is fully interchangeable with SMA5J6.0A-E3/61 in circuit design - only material compliance differs.
What is the reverse leakage current of the SMA5J6.0A-M3/61 at its stand-off voltage?
The SMA5J6.0A-M3/61 exhibits a maximum reverse leakage current (ID) of 800 μA at its rated stand-off voltage (VWM) of 6.0 V, tested at TA = 25 °C. This leakage remains well below 1 mA across the full operating temperature range, ensuring minimal impact on low-power 6 V circuits such as sensor bias networks or microcontroller VDD monitors. The low ID is enabled by Vishay's glass-passivated junction process, which stabilizes leakage behavior over time and temperature - a key factor in long-life industrial deployments.
Can the SMA5J6.0A-M3/61 be used in bidirectional configurations?
No - the SMA5J6.0A-M3/61 is strictly a unidirectional TVS diode, as indicated by its part number suffix "A" (versus "CA" for bidirectional types like SMA5J6.0CA). Its cathode is marked with a band, and it conducts only in reverse bias during overvoltage events. Attempting to use it in bidirectional mode would result in forward conduction and failure during positive transients. For bidirectional protection at 6 V, the SMA5J6.0CA-M3/61 must be selected instead - which has symmetric clamping in both directions and no polarity marking.
