Product details
Overview
SMPC5.0A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® Series, designed for clamping transient overvoltages on signal and power lines. It features a 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), 10.0 V clamping voltage at 150 A, and operates within -55 °C to +150 °C junction temperature range. It is used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the SMPC5.0A-M3/86A datasheet, SMPC5.0A-M3/86A pinout, SMPC5.0A-M3/86A application, or SMPC5.0A-M3/86A equivalent, key selection criteria include unidirectional polarity, TO-277A (SMPC) package compatibility, 1.1 mm profile for space-constrained PCBs, AEC-Q101 qualification status (not applicable to this variant), and clamping performance under 10/1000 μs surge conditions.
Technical Context
This TVS diode uses silicon avalanche technology to provide fast-response transient suppression with low incremental surge resistance and excellent clamping capability. Its unidirectional configuration allows integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
The device is optimized for automated placement and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. The cathode band denotes polarity, and thermal performance is characterized per JEDEC 51-2A (RθJA = 85–100 °C/W) and JEDEC 51-14 (RθJM = 2.5–3.0 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (min/max) | 6.40 V / 7.07 V - Breakdown occurs within this range at 10 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 10.0 V - Clamping voltage at 150 A peak pulse (10/1000 μs); limits downstream voltage stress during transients. |
| PPPM | 1500 W - Peak pulse power handling capacity; determines survivability against high-energy surges. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood or industrial ambient environments. |
| Package | SMPC (TO-277A) - 3-terminal surface-mount outline with 1.1 mm typical height; supports high-density layout and automated assembly. |
Pinout & Package
SMPC5.0A-M3/86A is housed in the SMPC (TO-277A) package - a 3-terminal, unidirectional surface-mount case with cathode band marking. Dimensions conform to JEDEC TO-277A: 4.80 × 3.70 × 1.10 mm (L × W × H), with 2.13 mm nominal standoff and 0.75 mm lead thickness. Mounting pad layout requires 6.80 mm × 4.72 mm footprint with 1.27 mm minimum solder mask clearance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Connected to protected line's positive side in unidirectional clamp configuration; forms one half of dual-anode structure. |
| Anode 2 | Secondary anode connection | Electrically tied to Anode 1 internally; provides mechanical symmetry and thermal path redundancy in SMPC package. |
| Cathode | Clamping output terminal | Connected to ground or low-impedance return; conducts surge current when VAK ≥ VBR; marked by band on package. |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile | 1.1 mm typical height enables use in ultra-thin consumer and automotive modules where Z-axis space is constrained. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for sensitive 3.3 V or 5 V logic interfaces. |
| Fast response time | Sub-nanosecond avalanche turn-on ensures clamping before transient energy damages downstream MOSFETs or sensors. |
| Halogen-free & RoHS-compliant | M3 suffix confirms compliance with environmental directives and material restrictions for industrial-grade deployment. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak, simplifying SMT manufacturing flow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VWM (5.0 V) and PPPM (400 W), but lower 400 W rating and SMA package (higher RθJA ≈ 150 °C/W). | Limited to lower-energy transients; unsuitable for 1500 W ISO 7637-2 Pulse 5a testing. | Select SMAJ5.0A only for cost-sensitive, low-surge-risk consumer applications where board space permits larger SMA footprint. |
| SMCJ5.0A | Same VWM (5.0 V) and higher PPPM (1500 W), but larger SMC (DO-214AB) package (2.5 mm height, 7.1 mm length). | Offers identical clamping (10.0 V @ 150 A) but requires more PCB area and has slower thermal recovery due to higher RθJA. | Choose SMCJ5.0A when existing SMC footprints exist or when higher mounting reliability is needed for vibration-prone environments. |
Compared with SMAJ5.0A and SMCJ5.0A, SMPC5.0A-M3/86A delivers identical 1500 W surge capability in a 45 % smaller footprint and 55 % lower profile, enabling next-generation compact designs without sacrificing clamping performance or thermal robustness.

FAQ
What is the clamping voltage of SMPC5.0A-M3/86A at its rated peak pulse current?
The SMPC5.0A-M3/86A has a maximum clamping voltage (VC) of 10.0 V when subjected to its peak pulse current (IPPM) of 150 A under a 10/1000 μs waveform. This value is measured with the cathode mounted on a heatsink and reflects worst-case voltage seen by protected circuitry during standardized surge events.
Is SMPC5.0A-M3/86A AEC-Q101 qualified?
No, SMPC5.0A-M3/86A is not AEC-Q101 qualified. Only variants with the HM3 suffix (e.g., SMPC22ANHM3) and part numbers from SMPC22AN through SMPC85AN are AEC-Q101 qualified. SMPC5.0A-M3/86A carries the M3 suffix, indicating halogen-free, RoHS-compliant, industrial-grade construction.
What does the /86A package code indicate for SMPC5.0A-M3/86A?
For SMPC5.0A-M3/86A, the /86A suffix specifies the preferred packaging format: 7-inch diameter plastic tape and reel containing 1500 units. This is distinct from /87A (13-inch reel, 6500 units) and is optimized for standard SMT pick-and-place feeders in medium-volume production.
How does the dual-anode configuration of SMPC5.0A-M3/86A affect PCB layout?
The SMPC5.0A-M3/86A features two anode terminals (Anode 1 and Anode 2) electrically shorted internally, allowing flexible routing on dense PCBs. Designers may connect either or both anodes to the protected line, improving current sharing and thermal distribution without altering electrical behavior.
Can SMPC5.0A-M3/86A be used in bidirectional transient protection applications?
No, SMPC5.0A-M3/86A is strictly unidirectional and must not be used for bidirectional AC-line or symmetrical transient protection. For such applications, a dedicated bidirectional TVS like SMPC5.0CA or SMAJ5.0CA is required; using SMPC5.0A-M3/86A would result in unintended conduction during negative half-cycles.
