Product details
Overview
SMA5J10CA-M3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 17.0 V at 29.4 A IPPM, and operates from –55 °C to +150 °C - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J10CA-M3/5A datasheet, SMA5J10CA-M3/5A pinout, SMA5J10CA-M3/5A application, or SMA5J10CA-M3/5A equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating with low clamping ratio, halogen-free RoHS-compliant construction (M3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical avalanche structure enables identical electrical characteristics in both polarities, with clamping performance validated under standardized 10/1000 µs waveform testing per ANSI/IEEE C62.35.
The device is rated for 500 W peak pulse power at TA = 25 °C, derated linearly above that temperature per Fig. 2, and exhibits 80 °C/W typical junction-to-ambient thermal resistance when mounted on minimum recommended pad layout. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before significant leakage; defines safe working margin for 12 V nominal systems. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 29.4 A - clamped voltage during 500 W surge; limits downstream IC stress to safe levels. |
| PPPM | 500 W (10/1000 µs) - energy-handling capacity for lightning and ESD-induced surges in automotive and industrial environments. |
| TJ max. | +150 °C - enables operation in under-hood automotive and high-temperature industrial enclosures without derating. |
| Package | SMA (DO-214AC) - surface-mount package with 5.28 mm × 4.50 mm footprint; compatible with standard reflow profiles and pick-and-place equipment. |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix); meets JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1. |
Pinout & Package
Package: SMA (DO-214AC), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between terminals; interchangeable connection for AC-coupled or floating signal lines. |
| Case (exposed cathode pad) | Thermal and mechanical anchor | Provides primary heat path to PCB copper; requires ≥5.0 mm × 5.0 mm pad per terminal for rated PPPM performance. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche behavior over 1000+ surge events without parameter drift. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during fast transients, protecting 12 V-rated logic and analog front-ends. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing without baking - reduces manufacturing overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10CA-E3/5A | RoHS-compliant but not halogen-free; same electrical specs and package; lead finish identical. | Preferred for commercial-grade non-automotive designs where halogen content is unrestricted. | Select SMA5J10CA-E3/5A when halogen-free requirement is absent and cost optimization is prioritized. |
| SMA6J10CA-M3/5A | 600 W PPPM rating (vs. 500 W), same VWM/VBR/VC, identical SMA package and M3 compliance. | Suitable for higher-risk surge environments (e.g., outdoor telecom, factory floor mains coupling). | Choose SMA6J10CA-M3/5A when system-level surge testing exceeds IEC 61000-4-5 Level 4 and 500 W margin is insufficient. |
Compared with SMA5J10CA-M3/5A, the E3 variant offers identical protection performance at lower material cost, while the SMA6J10CA-M3/5A extends surge headroom by 20 % without changing PCB layout or thermal design - enabling scalable robustness across product tiers.

FAQ
What is the clamping voltage of the SMA5J10CA-M3/5A under maximum rated surge current?
The SMA5J10CA-M3/5A clamps to 17.0 V at its peak pulse current (IPPM) of 29.4 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects the maximum voltage seen by protected circuitry during worst-case surge events. The SMA5J10CA-M3/5A maintains this clamping performance due to its low incremental surge resistance and symmetrical bidirectional junction design.
Is SMA5J10CA-M3/5A suitable for automotive applications?
The SMA5J10CA-M3/5A itself is commercial-grade, but Vishay offers AEC-Q101 qualified versions under HM3 suffix (e.g., SMA5J10CAHM3_A/I). The SMA5J10CA-M3/5A shares identical die, package, and electrical characteristics with those qualified variants - enabling seamless qualification path. Its -55 °C to +150 °C operating range and MSL Level 1 rating align with automotive under-hood requirements.
How does the bidirectional nature of SMA5J10CA-M3/5A affect PCB layout?
The SMA5J10CA-M3/5A has no polarity marking and identical electrical behavior in both directions, so PCB layout requires no orientation constraint. Both terminals connect symmetrically - one to the protected line, the other to ground - eliminating assembly errors and simplifying routing for AC-coupled or floating signals. This symmetry also avoids skew in differential protection schemes.
What is the thermal resistance of SMA5J10CA-M3/5A, and how does it impact surge handling?
The SMA5J10CA-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value directly determines derating above 25 °C: for example, at 85 °C ambient, its PPPM drops to ~350 W. Proper pad sizing is essential to sustain full 500 W rating - undersized pads increase RθJA and risk thermal runaway during repeated surges.
Does SMA5J10CA-M3/5A meet lead-free and halogen-free compliance standards?
Yes - the "M3" suffix explicitly denotes halogen-free, RoHS-compliant construction per Vishay's material categorization standard (doc?99912). The device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. It is fully compatible with lead-free reflow profiles up to 260 °C peak temperature.
