Product details
Overview
SMPC5.0A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, 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), and 10.0 V maximum clamping voltage (VC) at 150 A IPPM - ideal for protecting MOSFETs and ICs in automotive and industrial control circuits.
For engineers reviewing the SMPC5.0A-M3/87A datasheet, SMPC5.0A-M3/87A pinout, SMPC5.0A-M3/87A application, or SMPC5.0A-M3/87A equivalent, key selection criteria include unidirectional polarity, 1.25 W steady-state power dissipation, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on FR4 PCBs with 2 oz copper.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to divert surge current away from sensitive downstream components. Its low incremental surge resistance and fast response time ensure effective suppression of transients induced by inductive load switching or ESD events.
The SMPC5.0A-M3/87A is thermally optimized for junction-to-mount (RθJM ≤ 3 °C/W) and junction-to-ambient (RθJA ≤ 100 °C/W) operation on standard FR4 PCB footprints. It supports continuous operation up to TJ = 150 °C and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum reverse working voltage before clamping begins; defines safe operating range for protected circuit |
| VBR min/max | 6.40 V / 7.07 V at 10 mA - guaranteed avalanche onset window ensures consistent turn-on behavior across production lots |
| VC @ IPPM | 10.0 V at 150 A - clamping voltage under 10/1000 μs surge; limits stress on downstream MOSFET gate or IC I/O |
| PPPM | 1500 W - peak pulse power handling capability; enables robust protection against ISO 7637-2 Pulse 1/2a/5a surges |
| PD @ 25 °C | 1.25 W - steady-state power dissipation limit; determines thermal derating needed for high ambient environments |
| TJ max | 150 °C - maximum junction temperature; sets upper bound for thermal design margin in enclosed enclosures |
| Polarity | Unidirectional - cathode-banded configuration; requires correct orientation in series with positive rail or signal line |
Pinout & Package
Package: SMPC (TO-277A), 3-terminal surface-mount case with matte tin-plated leads, 1.1 mm typical height, UL 94 V-0 molding compound, and cathode band marking.

| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak without baking, simplifying manufacturing flow |
| Halogen-free, RoHS-compliant | Meets global environmental compliance requirements including EU RoHS Directive 2011/65/EU and JEDEC J-STD-20 |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for 3.3 V or 5 V logic interfaces |
| Excellent clamping capability (VC = 10.0 V @ 150 A) | Provides tight voltage limiting for sensitive gate drivers and microcontroller I/O pins exposed to load-dump conditions |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Stage |

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-E3/5A | DO-214AC (SMA) package; higher RθJA (~150 °C/W); same VWM/VBR/VC specs | Larger footprint and lower power density; less suitable for ultra-thin modules | Preferred where legacy SMA layout exists and height >1.1 mm is acceptable |
| SMCJ5.0A-M3/87A | SMC (DO-214AB) package; 1500 W PPPM but larger body (2.7 mm height); identical electrical specs | Better thermal mass for sustained surge duty; incompatible with SMPC land pattern | Select when higher thermal inertia is required and board height allows ≥2.7 mm |
Compared with SMAJ5.0A-E3/5A and SMCJ5.0A-M3/87A, the SMPC5.0A-M3/87A delivers identical clamping performance in a 1.1 mm profile optimized for modern compact designs - making it the preferred choice where board thickness, automated placement yield, and MSL Level 1 compliance are critical.

FAQ
What is the mounting configuration for SMPC5.0A-M3/87A?
The SMPC5.0A-M3/87A uses a 3-terminal SMPC (TO-277A) surface-mount package with two anode terminals (Anode 1 and Anode 2) and one cathode terminal marked by a band. It mounts directly onto FR4 PCBs using standard reflow profiles compliant with J-STD-020 MSL Level 1, with recommended pad layout per Vishay document 89116.
Does SMPC5.0A-M3/87A meet AEC-Q101 qualification?
No, SMPC5.0A-M3/87A is not AEC-Q101 qualified. The AEC-Q101 version carries the HM3 suffix (e.g., SMPC5.0AHM3), and qualification applies only to SMPC22AN through SMPC85AN variants per Vishay documentation. SMPC5.0A-M3/87A is industrial-grade, halogen-free, and RoHS-compliant.
What is the maximum clamping voltage of SMPC5.0A-M3/87A under surge conditions?
The SMPC5.0A-M3/87A has a maximum clamping voltage (VC) of 10.0 V at 150 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 89116 and defines the upper voltage limit imposed on protected circuitry during transient events.
Can SMPC5.0A-M3/87A be used in bidirectional configurations?
No, SMPC5.0A-M3/87A is strictly unidirectional. Its internal structure and cathode-band marking require connection with anode toward the protected line and cathode toward ground. For bidirectional protection, Vishay offers separate SMPCxxCA variants - SMPC5.0A-M3/87A does not support reverse-polarity conduction.
What is the thermal resistance specification for SMPC5.0A-M3/87A?
The SMPC5.0A-M3/87A has a typical junction-to-mount thermal resistance (RθJM) of 2.5 °C/W and a maximum of 3.0 °C/W, and a junction-to-ambient resistance (RθJA) up to 100 °C/W when mounted on a standard FR4 PCB with 2 oz copper. These values are defined per JEDEC 51-14 (RθJM) and JEDEC 51-2A (RθJA).
