Product details
Overview
SMPC7.5A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMPC (TO-277A) package, with 7.5 V stand-off voltage (VWM), 8.33–9.21 V breakdown voltage (VBR), 12.9 V clamping voltage at 100 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs and ICs in automotive and industrial power supply lines against inductive switching transients.
For engineers reviewing the SMPC7.5A-M3/86A datasheet, SMPC7.5A-M3/86A pinout, SMPC7.5A-M3/86A application, or SMPC7.5A-M3/86A equivalent, key selection criteria include unidirectional polarity, 1.1 mm profile for space-constrained PCB layouts, AEC-Q101 qualification eligibility (via HM3 suffix), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on FR4 boards.
Technical Context
The SMPC7.5A-M3/86A operates as a silicon avalanche diode designed for fast clamping of transient overvoltages using a 10/1000 μs waveform. Its low incremental surge resistance and sub-nanosecond response time enable effective suppression of ESD and load-dump events before downstream components are damaged.
Thermal performance is defined by RθJA ≤ 100 °C/W (mounted on 2 oz FR4 standard footprint) and maximum junction temperature of 150 °C. The device features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing.
Key Specifications

Pinout & Package
SMPC7.5A-M3/86A uses the SMPC (TO-277A) package: a 3-terminal, single-anode dual-cathode configuration where the banded end denotes the cathode. The package has a 1.1 mm typical height, meets UL 94 V-0 flammability rating, and supports automated placement per J-STD-020 MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | Common anode node shared with Anode 2; connects to protected circuit ground or return path |
| Anode 2 | Secondary anode connection | Electrically tied to Anode 1 internally; provides mechanical stability and thermal conduction via dual-anode layout |
| Cathode | Transient current sink | Banded terminal; carries full surge current to ground during clamping; must be routed with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in ultra-thin consumer and automotive modules where Z-height is constrained |
| Unidirectional polarity | Protects DC-biased lines (e.g., 12 V power rails) without interfering with normal forward conduction |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping precision |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without pre-baking or special handling |
| Halogen-free, RoHS-compliant | Fulfills environmental compliance requirements for global industrial and automotive shipments |
Applications
| Automotive Power Rail Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to 35 V and inductive switch-off spikes. IC Role / Device Role / Timing Role: Transient voltage suppressor placed at power entry point, clamping surges before they reach DC-DC converters and microcontrollers. Use Value: Limits clamped voltage to 12.9 V at 100 A, preventing latch-up or gate oxide damage in downstream 16 V-rated ICs. | Use Scenario: Safeguarding digital input channels of programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Unidirectional TVS shunting induced surges on 24 V sensor signal lines connected to isolated inputs. Use Value: Sub-ns response ensures clamping occurs before transient propagates into optocoupler or ADC front-end stages. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Protection |
Use Scenario: Suppressing line-side surges in AC-DC adapters used in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Primary-side TVS on rectified DC bus, absorbing energy from lightning-induced surges coupled through mains. Use Value: 1500 W PPPM rating handles IEC 61000-4-5 Level 3 (1 kV/2 Ω) test pulses without degradation. | Use Scenario: Preventing gate oxide failure in N-channel power MOSFETs driven by microcontrollers in motor control H-bridges. IC Role / Device Role / Timing Role: Localized TVS across gate-source terminals to clamp Miller-induced voltage spikes during high dV/dt switching. Use Value: 1.0 μA IR at 7.5 V ensures no measurable leakage current interferes with precise gate drive timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-E3/5AT | DO-214AC package; 1.8 mm height; 7.5 V VWM; 12.9 V VC at 72.5 A; 400 W PPPM | Lower power rating and taller profile limit use in high-surge or ultra-low-Z applications | Select when board space allows larger footprint and surge energy is ≤ 400 W |
| SMCJ7.5A-M3/86A | SMC (DO-214AB) package; 2.6 mm height; same VWM/VC specs; 1500 W PPPM; higher thermal mass | Greater board area and Z-height required; better sustained power dissipation but less suitable for thin modules | Select when thermal cycling reliability under repeated surges is prioritized over profile constraints |
Compared with SMAJ7.5A-E3/5AT and SMCJ7.5A-M3/86A, the SMPC7.5A-M3/86A delivers identical clamping performance in a 1.1 mm profile-critical for automotive ADAS modules and portable industrial sensors where vertical clearance is limited to < 1.2 mm.

FAQ
What is the mounting configuration for SMPC7.5A-M3/86A?
The SMPC7.5A-M3/86A uses a 3-terminal SMPC (TO-277A) package with dual anodes (Anode 1 and Anode 2) and a single cathode marked by a band. Both anodes are internally connected and intended for common grounding; the cathode connects to the protected line. Mounting requires a standardized 2 oz FR4 footprint per Vishay's recommended pad layout.
Is SMPC7.5A-M3/86A qualified for automotive applications?
SMPC7.5A-M3/86A is halogen-free, RoHS-compliant, and industrial-grade. While it belongs to the AEC-Q101-qualified SMPC family, only variants with the HM3 suffix (e.g., SMPC7.5AHM3/86A) carry formal AEC-Q101 certification. For automotive use, specify the HM3 version to ensure qualification documentation and test reports.
What is the maximum peak pulse current rating for SMPC7.5A-M3/86A?
The SMPC7.5A-M3/86A has a maximum peak pulse current (IPPM) of 100 A under the standard 10/1000 μs waveform condition. This value is derived from its 12.9 V clamping voltage and 1500 W peak pulse power rating (P = V × I), and is validated per Figure 1 in Vishay document 89116.
Does SMPC7.5A-M3/86A require derating at elevated ambient temperatures?
Yes. The SMPC7.5A-M3/86A must be derated above TA = 25 °C per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power drops to approximately 75 % of rated 1500 W, and its steady-state power dissipation falls to ~0.6 W. Thermal design must account for RθJA ≤ 100 °C/W on standard FR4.
Can SMPC7.5A-M3/86A be used in bidirectional configurations?
No. SMPC7.5A-M3/86A is strictly unidirectional, with polarity indicated by the cathode band. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional TVS such as the SMBJ7.5CA-M3/86A. Using SMPC7.5A-M3/86A in reverse bias beyond VWM risks permanent damage due to lack of symmetrical avalanche structure.
