Product details
Overview
SMA5J10CA-M3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage (VC) at 29.4 A peak pulse current, and 500 W peak pulse power dissipation with 10/1000 µs waveform.
For engineers reviewing the SMA5J10CA-M3/61 datasheet, SMA5J10CA-M3/61 pinout, SMA5J10CA-M3/61 application, or SMA5J10CA-M3/61 equivalent, this device is selected for high-energy surge immunity in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning where bidirectional clamping and halogen-free RoHS compliance are required.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection against positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time (<1 ns), critical for safeguarding sensitive analog and digital inputs.
The device is rated for continuous operation from −55 °C to +150 °C junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its low incremental surge resistance supports effective clamping under high-current surges such as ISO 7637-2 Pulse 1/2a/5a or IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 11.1 V / 12.3 V - Voltage at which device enters avalanche conduction at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 17.0 V at 29.4 A - Clamped voltage during 500 W surge; limits stress on downstream components like MCUs or transceivers. |
| PPPM | 500 W - Peak pulse power handling with 10/1000 µs waveform; supports high-energy transients common in automotive and industrial environments. |
| ID @ VWM | <1.0 µA - Reverse leakage at stand-off voltage; minimizes quiescent power loss and avoids false triggering in low-power systems. |
| TJ max. | +150 °C - Maximum junction temperature; enables reliable operation in under-hood automotive or enclosed industrial enclosures. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no polarity marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identically as input/output nodes for bidirectional clamping; no cathode band or polarity identification required. |
| Case (body) | Thermal and mechanical interface | Plastic body provides electrical isolation; copper pad mounting per 5.0 mm × 5.0 mm layout optimizes thermal dissipation and surge current handling. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN FD, sensor bridges) without external polarity management. |
| 500 W peak pulse power | Withstands high-energy transients per IEC 61000-4-5 Level 4 (4 kV line-earth, 2 kV line-line) when mounted on recommended PCB pads. |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage overshoot during surge events, reducing risk of latch-up or gate oxide damage in connected ICs. |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for automotive and industrial OEMs without compromising surge performance or thermal reliability. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |

IC Role / Device Role / Timing Role: Bidirectional clamping element placed immediately after USB connector, before ESD-rated transceiver IC. Use Value: Sub-1 ns response time and <1 µA leakage preserve signal rise/fall times and prevent false disconnect detection during ±8 kV contact ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10CA-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3). | Acceptable for commercial-grade designs where halogen-free requirement is not mandated. | Select E3 for cost-sensitive non-automotive applications; M3 required for automotive Tier 1 compliance. |
| SMBJ10CA-M3 | Same VWM/VC, but SMB package (DO-214AA); 600 W PPPM, higher thermal mass, larger footprint. | Better suited for higher-surge environments (e.g., motor drives) where PCB space allows larger package. | Choose SMBJ10CA-M3 if surge margin >500 W is needed; SMA5J10CA-M3 preferred for space-constrained layouts. |
Compared with SMA5J10CA-E3/61 and SMBJ10CA-M3, the SMA5J10CA-M3/61 uniquely balances halogen-free compliance, compact SMA footprint, and 500 W surge capability-making it optimal for automotive sensor modules and dense industrial PCBs where material content and board area are constrained.

FAQ
What is the clamping voltage of the SMA5J10CA-M3/61 under maximum surge conditions?
The SMA5J10CA-M3/61 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current of 29.4 A, measured using the standardized 10/1000 µs waveform. This value ensures protected downstream components-such as microcontrollers or transceivers-remain within their absolute maximum voltage ratings during surge events. The SMA5J10CA-M3/61 achieves this clamping performance while maintaining low leakage and fast response, making it suitable for precision analog and high-speed digital interfaces.
Is the SMA5J10CA-M3/61 suitable for automotive applications?
Yes, the SMA5J10CA-M3/61 is halogen-free and RoHS-compliant (M3 suffix), and the base SMA5J10CA family is AEC-Q101 qualified when ordered with HE3 or HM3 suffixes. While the M3/61 variant itself is commercial-grade, its electrical specs, thermal rating (−55 °C to +150 °C), and construction (glass-passivated junction, MSL Level 1) align with automotive environmental demands. For full qualification, specify SMA5J10CAHM3_A/H; the SMA5J10CA-M3/61 remains widely used in automotive subsystems where system-level validation covers the component.
How does the bidirectional design of the SMA5J10CA-M3/61 affect PCB layout?
The SMA5J10CA-M3/61 has no polarity marking-its symmetrical bidirectional structure eliminates the need for orientation checks during automated placement. This simplifies layout by allowing either terminal to connect to the line being protected, ideal for differential or AC-coupled signals like RS-485, CAN, or sensor bridges. Unlike unidirectional TVS diodes, the SMA5J10CA-M3/61 avoids risk of incorrect installation and supports identical routing on both sides of balanced interfaces without additional design constraints.
What is the thermal resistance of the SMA5J10CA-M3/61, and how does it impact surge handling?
The SMA5J10CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. This value directly affects its ability to dissipate heat during repetitive surges: lower RθJA improves thermal recovery between pulses. For single-event transients (e.g., ESD or lightning), thermal mass dominates; for repetitive surges, proper pad layout per the datasheet is essential to maintain the SMA5J10CA-M3/61 within its 150 °C TJ limit and avoid derating.
Can the SMA5J10CA-M3/61 replace a unidirectional TVS like SMA5J10A-M3/61 in an existing design?
No-the SMA5J10CA-M3/61 is bidirectional and lacks polarity marking, whereas SMA5J10A-M3/61 is unidirectional with a cathode band. Swapping them requires verifying that the protected circuit can tolerate symmetrical clamping (e.g., floating or AC-coupled lines). In DC-biased circuits (e.g., 5 V power rail), a unidirectional device is mandatory; using SMA5J10CA-M3/61 there would allow forward conduction and potential failure. Always confirm signal topology before substituting SMA5J10CA-M3/61 for unidirectional variants.
