Product details
Overview
SMPC9.0A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for clamping voltage transients on power and signal lines. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR), 15.4 V maximum clamping voltage (VC) at 5.0 A peak pulse current, and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - ideal for protecting MOSFETs and sensor signal lines in industrial control systems.
For engineers reviewing the SMPC9.0A-M3/87A datasheet, SMPC9.0A-M3/87A pinout, SMPC9.0A-M3/87A application, or SMPC9.0A-M3/87A equivalent, key selection criteria include unidirectional polarity, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on FR4 PCBs.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 9.0 V stand-off voltage and rapidly transitions to low-impedance conduction above its 10.0–11.1 V breakdown threshold. Its 15.4 V clamping voltage at 5.0 A ensures downstream ICs experience minimal overvoltage during transient events such as inductive load switching.
The SMPC9.0A-M3/87A uses a planar junction structure in a dual-anode/single-cathode SMPC (TO-277A) configuration, enabling high surge current handling (IPPM = 5.0 A) while maintaining low incremental surge resistance and sub-nanosecond response time. Thermal performance is characterized by RθJA ≤ 100 °C/W on standard 2 oz FR4 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum reverse voltage before significant leakage; defines safe operating margin for 9 V nominal rails |
| VBR min/max | 10.0 V / 11.1 V at 1.0 mA - guaranteed breakdown onset range; ensures predictable turn-on under ESD or surge |
| VC @ IPPM | 15.4 V at 5.0 A (10/1000 μs) - clamped voltage seen by protected circuit; limits stress on 3.3 V or 5 V logic interfaces |
| PPPM | 1500 W - peak transient energy absorption capability; supports IEC 61000-4-5 Level 4 surge immunity |
| IR @ VWM | 1.0 μA - ultra-low reverse leakage at rated stand-off; avoids parasitic loading on sensitive analog/sensor lines |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with cathode band marking; 1.1 mm profile enables dense layout |
| TJ max | +150 °C - extended junction temperature rating allows operation in automotive under-hood or industrial motor drive environments |
Pinout & Package
SMPC9.0A-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 on the top surface. The device is unidirectional with dual anodes and a common cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for transient path | Connected to protected line (e.g., 9 V supply rail); forms one half of parallel anode structure |
| Anode 2 | Input terminal for transient path | Electrically tied to Anode 1 internally; provides symmetrical surge current sharing and thermal distribution |
| Cathode | Clamp output / reference node | Connected to ground or low-impedance return; carries full surge current during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in space-constrained modules like motor controllers and portable instrumentation without height interference |
| Unidirectional polarity | Supports DC-biased protection only - prevents false triggering on AC-coupled or bidirectional signal lines |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak - eliminates bake requirements and simplifies manufacturing |
| AEC-Q101 qualified variant available | Base P/NHM3 suffix indicates qualification for automotive applications; SMPC9.0A-M3/87A is industrial grade (M3 suffix) |
| Halogen-free & RoHS-compliant | Meets environmental compliance mandates for industrial and consumer electronics without compromising surge robustness |
Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Same VWM (9.0 V) and VC (15.4 V), but SMA package (higher RθJA ≈ 150 °C/W) and lower PPPM (400 W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when board space allows larger SMA footprint and surge energy is ≤400 W |
| SMCJ9.0A | Same VWM and VC, but SMC package (3.5 mm height), higher PPPM (1500 W), and higher IPPM (125 A) | Better thermal mass for repeated surges; taller profile may conflict with mechanical enclosures | Select when higher surge repetition rate or longer thermal time constants are required |
Compared with SMAJ9.0A and SMCJ9.0A, the SMPC9.0A-M3/87A delivers identical clamping performance in a 1.1 mm low-profile package optimized for automated assembly and dense layouts - making it preferred for modern compact industrial and telecom modules where height and MSL Level 1 compliance are critical.

FAQ
What is the polarity configuration of the SMPC9.0A-M3/87A?
The SMPC9.0A-M3/87A is a unidirectional TVS diode with dual anodes and a common cathode. The cathode is marked by a band on the top surface. This configuration allows it to conduct only during positive transients relative to ground, making it suitable for DC-biased protection applications where reverse voltage must be blocked.
Does the SMPC9.0A-M3/87A meet automotive qualification standards?
No - the SMPC9.0A-M3/87A carries the M3 suffix, indicating halogen-free, RoHS-compliant, industrial-grade construction. For AEC-Q101 qualification, Vishay offers the SMPC9.0ANHM3 variant (with HM3 suffix). The SMPC9.0A-M3/87A is not rated for automotive under-hood or safety-critical applications.
What is the maximum clamping voltage of the SMPC9.0A-M3/87A and at what test condition?
The SMPC9.0A-M3/87A has a maximum clamping voltage (VC) of 15.4 V, measured at 5.0 A peak pulse current using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value defines the upper voltage limit imposed on protected circuitry during surge events.
Can the SMPC9.0A-M3/87A be used in bidirectional signal line protection?
No - the SMPC9.0A-M3/87A is strictly unidirectional and conducts only for positive transients. For bidirectional protection (e.g., USB, RS-485, or AC-coupled lines), a symmetric TVS array or dedicated bidirectional part such as SMF9.0A is required. Using SMPC9.0A-M3/87A on bidirectional lines risks failure during negative excursions.
What is the moisture sensitivity level (MSL) rating for SMPC9.0A-M3/87A?
The SMPC9.0A-M3/87A is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can withstand reflow soldering at a maximum peak temperature of 260 °C without preconditioning or baking. This simplifies SMT manufacturing and eliminates moisture-related popcorning risk.
