Product details
Overview
SMPC9.0A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® SMPC (TO-277A) package, designed for clamping transient overvoltages 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 (10/1000 μs). It is used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics against inductive switching transients.
For engineers reviewing the SMPC9.0A-M3/86A datasheet, SMPC9.0A-M3/86A pinout, SMPC9.0A-M3/86A application, or SMPC9.0A-M3/86A equivalent, this page delivers verified electrical parameters, thermal derating behavior, JEDEC-compliant SMPC package dimensions, AEC-Q101 qualification status, and real-world protection use cases - all aligned with Vishay Document 89116 (Rev. 17-Sep-2021).
Technical Context
This device operates as a unidirectional avalanche diode, leveraging silicon p-n junction physics to clamp voltage surges above its breakdown threshold while maintaining low leakage (<1.0 μA at VWM) below that threshold. Its low incremental surge resistance and fast response time enable effective suppression of sub-microsecond transients induced by relay switching or motor commutation.
The SMPC9.0A-M3/86A is mounted in a two-anode / one-cathode configuration (Anode 1, Anode 2, Cathode) per the SMPCxxA family layout, with cathode polarity indicated by a band. Thermal performance is characterized by RθJA ≤ 100 °C/W (FR4, 2 oz copper) and RθJM ≤ 3.0 °C/W, supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum reverse working voltage before significant conduction begins; defines safe operating margin for 9 V nominal supply rails. |
| VBR @ IT = 1 mA | 10.0–11.1 V - Breakdown voltage range at 1 mA test current; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM = 5.0 A | 15.4 V - Clamped voltage under 10/1000 μs surge; limits stress on downstream 12–15 V logic or gate drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A-E3/52 | Same VWM (9.0 V), same unidirectional topology, but SMB package (higher profile: 2.3 mm) and lower PPPM (600 W). | Less suitable for ultra-low-height designs; adequate for lower-energy transients in consumer-grade power supplies. | Select SMBJ9.0A-E3/52 only if board height > 2.3 mm is acceptable and surge energy is < 600 W. |
| SMCJ9.0AHE3/73 | Same VWM (9.0 V), higher PPPM (1500 W), but larger SMC package (7.1 mm × 6.2 mm) and higher RθJA (~50 °C/W). | Better thermal mass for sustained surges, but incompatible with dense layouts requiring SMPC footprint. | Choose SMCJ9.0AHE3/73 when thermal dissipation dominates over board area constraints and mechanical clearance permits larger body size. |
Compared with SMPC9.0A-M3/86A, SMBJ9.0A-E3/52 trades pulse power and profile for cost and availability, while SMCJ9.0AHE3/73 prioritizes thermal robustness over miniaturization - making SMPC9.0A-M3/86A the optimal balance of low height, high surge rating, and industrial reliability in space-limited 24 V systems.

FAQ
What is the maximum clamping voltage of the SMPC9.0A-M3/86A under a 10/1000 μs surge?
The SMPC9.0A-M3/86A has a maximum clamping voltage (VC) of 15.4 V when subjected to a 5.0 A peak pulse current with a 10/1000 μs waveform, as specified in Vishay Document 89116. This value ensures downstream 12 V logic and analog circuits remain within safe operating limits during transient events. The SMPC9.0A-M3/86A maintains this clamping performance across its full operating temperature range.
Is the SMPC9.0A-M3/86A AEC-Q101 qualified?
No, the SMPC9.0A-M3/86A is not AEC-Q101 qualified. Per Vishay's ordering information and qualification notes, AEC-Q101 qualification applies only to parts with the HM3 suffix (e.g., SMPC22ANHM3) and is limited to the SMPC22AN through SMPC85AN variants. The SMPC9.0A-M3/86A carries the M3 suffix and is rated for industrial-grade operation only.
What does the /86A package code indicate for SMPC9.0A-M3/86A?
Per Vishay Document 89116, the /86A suffix denotes a 7-inch diameter plastic tape-and-reel packaging format containing 1500 units per reel. It is one of two standard delivery options for the SMPC5.0A-M3 through SMPC36A-M3 series, with /87A indicating the 13-inch reel (6500 units). The /86A code does not affect electrical or thermal specifications of the SMPC9.0A-M3/86A device itself.
How is polarity identified on the SMPC9.0A-M3/86A package?
The SMPC9.0A-M3/86A uses a cathode band to denote polarity, located adjacent to the cathode terminal per the SMPC (TO-277A) outline drawing. As a unidirectional TVS, correct orientation is critical: the cathode must be connected toward the side of the circuit being protected (e.g., VCC rail), while both anodes connect to ground or return path. Reversal prevents proper clamping and risks device failure.
What is the thermal resistance junction-to-ambient for SMPC9.0A-M3/86A?
The SMPC9.0A-M3/86A 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 the recommended pad layout per Vishay Document 89116. Its typical RθJA is 85 °C/W. This value assumes no additional heatsinking; actual thermal performance depends on PCB copper area and airflow.
