Product details
Overview
SMPC10A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMPC (TO-277A) package, with 10.0 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM). It clamps transients to ≤17.0 V at 2.0 A IPPM and operates from –55 °C to +150 °C, protecting MOSFETs and ICs against inductive switching surges in automotive and industrial power rails.
For engineers reviewing the SMPC10A-M3/87A datasheet, SMPC10A-M3/87A pinout, SMPC10A-M3/87A application, or SMPC10A-M3/87A equivalent, key selection criteria include unidirectional polarity, 1.1 mm profile for space-constrained PCBs, MSL Level 1 reflow compatibility, halogen-free RoHS-compliant construction, and AEC-Q101 qualification eligibility via HM3 suffix variants.
Technical Context
This device functions as a clamping-type TVS diode optimized for fast response (<1 ns) to 10/1000 μs surge waveforms. Its low incremental surge resistance and 17.0 V clamping voltage at 2.0 A ensure robust protection of downstream 12 V rail components without overvoltage stress.
The SMPC10A-M3/87A uses a planar junction structure in a dual-anode/single-cathode SMPC (TO-277A) configuration - confirmed by Vishay's mechanical drawing and pinout diagram - enabling high-current capability while maintaining low thermal resistance (RθJA ≤ 100 °C/W on FR4).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 11.1 V / 12.3 V at 10 mA - ensures reliable turn-on above nominal rail voltage with margin |
| VC @ IPPM | 17.0 V at 2.0 A - clamping voltage limits protected circuit stress during 10/1000 μs surge |
| PPPM | 1500 W - peak power handling for standardized lightning/surge immunity per IEC 61000-4-5 |
| TJ max. | +150 °C - supports under-hood automotive and high-temperature industrial environments |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm typical height and J-STD-020 MSL Level 1 rating |
| Polarity | Unidirectional - cathode-band marked terminal enables correct orientation for DC rail protection |
Pinout & Package
SMPC10A-M3/87A uses the SMPC (TO-277A) package: a 3-terminal surface-mount outline conforming to JEDEC TO-277A, with 1.1 mm typical height, matte tin-plated leads, and cathode band marking. Mounting pad layout requires 0.268" × 0.186" footprint per Vishay mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary current input path | Connected to protected line (e.g., 12 V supply rail); forms one half of parallel anode structure |
| Anode 2 | Secondary current input path | Electrically tied to Anode 1 internally; doubles surge current capacity without added trace inductance |
| Cathode (band-marked) | Clamping output node | Connected to ground or low-impedance return; defines unidirectional conduction direction and clamping reference |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables placement beneath low-clearance shields or in ultra-thin modules without mechanical interference |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning or special bake cycles |
| Halogen-free & RoHS-compliant | Fulfills environmental compliance requirements for EU, China RoHS, and automotive Tier-1 supply chains |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| Fast response time (<1 ns) | Engages before sensitive gate oxides or logic inputs experience damaging overvoltage |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery rail and DC-DC input, absorbing up to 1500 W surges. Use Value: Limits clamped voltage to 17.0 V, preventing overvoltage damage to upstream regulators and microcontrollers. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt ESD and inductive kickback from relay coils or solenoids. Use Value: Sub-1 ns response and 17.0 V clamping prevent latch-up or parametric shift in precision ADC front-ends. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Line Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and AC/DC wall adapters. IC Role / Device Role / Timing Role: Clamping device across +VOUT and GND after primary-side regulation, catching transformer leakage spikes. Use Value: 1500 W PPPM handles repetitive surge events common in unregulated adapter topologies without degradation. | Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras, wireless APs) from induced surges on 48 V DC feeder lines. IC Role / Device Role / Timing Role: Unidirectional TVS installed at PD interface to clamp common-mode transients coupled onto data+power pairs. Use Value: 10.0 V VWM matches 48 V system derating (≈10% margin), while 17.0 V VC avoids false triggering of 3.3 V/5 V logic supervisors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5A | DO-214AC package; 10.0 V VWM; 17.0 V VC @ 2.0 A; 400 W PPPM | Lower power rating limits use to sub-400 W surge environments; larger footprint (2.79 mm height) | Select when board space allows larger package and surge energy is ≤400 W |
| SMCJ10AHE3/57T | DO-214AB package; 10.0 V VWM; 17.0 V VC @ 2.0 A; 1500 W PPPM; AEC-Q101 qualified | Same clamping performance but larger 7.11 mm × 6.22 mm body; not MSL Level 1 rated | Select when AEC-Q101 qualification is mandatory and 1.1 mm height constraint is relaxed |
Compared with SMAJ10A-E3/5A and SMCJ10AHE3/57T, the SMPC10A-M3/87A delivers identical 10 V/17 V electrical performance in a 1.1 mm low-profile package with MSL Level 1 compatibility - making it optimal for high-density automotive and portable industrial designs where height and reflow robustness are critical.

FAQ
What is the clamping voltage of the SMPC10A-M3/87A at its rated peak pulse current?
The SMPC10A-M3/87A has a maximum clamping voltage (VC) of 17.0 V at 2.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 in Vishay Document 89116 and defines the upper voltage limit imposed on protected circuits during surge events. The SMPC10A-M3/87A maintains this clamping performance across its full operating temperature range.
Is the SMPC10A-M3/87A AEC-Q101 qualified?
No, the SMPC10A-M3/87A is not AEC-Q101 qualified. Per Vishay's ordering information and notes in Document 89116, AEC-Q101 qualification applies only to SMPCxxAN variants with HM3 suffix (e.g., SMPC22ANHM3). The SMPC10A-M3/87A carries the industrial-grade M3 suffix and meets RoHS, halogen-free, and MSL Level 1 requirements, but lacks automotive qualification. For AEC-Q101 needs, consider SMPC22ANHM3 or higher-voltage AN-series parts.
What does the /87A suffix indicate in SMPC10A-M3/87A?
Per Vishay's ordering table in Document 89116, the /87A suffix denotes packaging: 13-inch diameter plastic tape and reel with 6500 units per reel. It does not affect electrical or thermal specifications. The base part SMPC10A-M3 remains functionally identical across /86A (1500/reel, 7″ reel) and /87A configurations. Both share identical SMPC (TO-277A) package dimensions, marking, and performance characteristics.
Can SMPC10A-M3/87A be used in bidirectional transient protection applications?
No, the SMPC10A-M3/87A is strictly unidirectional, as confirmed by its "A" suffix designation, polarity band marking, and electrical specifications (VBR defined only for forward-biased cathode configuration). Bidirectional operation would require an "CA" variant (e.g., SMPC10CA) or dual-diode configuration. Using SMPC10A-M3/87A in AC or bipolar signal paths risks reverse breakdown and permanent failure.
What is the thermal resistance junction-to-ambient for SMPC10A-M3/87A?
The SMPC10A-M3/87A has a maximum junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and Vishay's recommended footprint. Typical RθJA is 85 °C/W under the same conditions. This value is specified in the Thermal Characteristics table of Document 89116 and directly impacts steady-state power dissipation limits - e.g., at 25 °C ambient, PD is limited to 1.25 W.
