Product details
Overview
SMPC36AN-M3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for high-energy surge protection of sensitive electronics. It features a 36.0 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 58.1 V maximum clamping voltage (VC) at 25.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform.
For engineers reviewing the SMPC36AN-M3/I datasheet, SMPC36AN-M3/I pinout, SMPC36AN-M3/I application, or SMPC36AN-M3/I equivalent, this device is selected for automotive-grade transient suppression on power rails and signal lines where low-profile mounting, AEC-Q101 qualification, and robust clamping under repetitive surge stress are required.
Technical Context
The SMPC36AN-M3/I operates as a unidirectional avalanche diode, leveraging silicon p-n junction physics to clamp transients above its breakdown threshold. Its thermal design supports operation up to +150 °C junction temperature, with RθJA ≤ 100 °C/W on FR4 PCB and RθJM ≤ 3.0 °C/W when mounted to heatsink.
It complies with J-STD-020 MSL Level 1 (260 °C peak reflow), meets UL 94 V-0 flammability, and uses matte tin-plated leads qualified per JESD 22-B102 and JESD 201 Class 2 whisker test - confirming suitability for automated SMT assembly and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36.0 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 40.0 V / 44.2 V - Breakdown occurs within this range at 1.0 mA test current, defining turn-on threshold tolerance |
| VC @ IPPM | 58.1 V - Clamped voltage across device during 25.8 A 10/1000 μs surge, limiting downstream stress |
| PPPM | 1500 W - Peak transient energy absorption capability, critical for ISO 7637-2 pulse 5a/b compliance |
| TJ max | +150 °C - Maximum junction temperature enabling use in under-hood automotive locations |
| Package | SMPC (TO-277A) - 3-terminal surface-mount outline with 1.1 mm typical height, optimized for space-constrained PCBs |
| AEC-Q101 | Qualified - Validated for automotive electronic systems per stress test requirements including HTOL, TCT, and ESD |
Pinout & Package
SMPC36AN-M3/I uses the SMPC (TO-277A) package: a 3-terminal surface-mount case with cathode band marking, 1.1 mm typical height, and JEDEC-compliant footprint. Terminals are matte tin-plated for solderability per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 & Anode 2 | Common anode connection | Internally tied anodes enable dual-path conduction; both must be connected identically for rated performance |
| Cathode | Clamping output terminal | Band-marked terminal; carries full surge current to ground or return path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile height | 1.1 mm typical - Enables placement beneath connectors or in ultra-thin modules without mechanical interference |
| Fast response time | < 1.0 ps - Sub-nanosecond junction response ensures clamping before IC damage thresholds are exceeded |
| Low incremental surge resistance | ~2.26 Ω derived from (VC − VBR)/IPPM - Minimizes voltage overshoot during fast-rising transients like EFT or lightning-induced surges |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics - Supports functional safety-aware designs without additional qualification effort |
| Halogen-free & RoHS | M3 suffix indicates industrial-grade compliance - Meets environmental regulations for global OEM supply chains |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Primary clamping element placed between power input and DC/DC converter input stage. Use Value: Limits voltage to ≤58.1 V during 25.8 A surge, preventing overvoltage failure of downstream regulators and microcontrollers. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional TVS on signal line between sensor and ADC input, referenced to system ground. Use Value: Clamps ESD (IEC 61000-4-2) and inductive kickback to <60 V, preserving 16-bit ADC accuracy and avoiding latch-up. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
Use Scenario: Front-end protection on AC/DC adapter inputs exposed to mains-borne surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: First-line defense before bridge rectifier and bulk capacitor, absorbing line-to-ground transients. Use Value: Withstands 1500 W peak pulse power, enabling compliance with Level 3 (2 kV/2 Ω) surge immunity testing. | Use Scenario: Secondary-side 5 V/12 V rail protection in USB-C PD adapters and smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor placed after DC/DC converter output, guarding SoC power pins. Use Value: 1.1 mm profile allows placement adjacent to BGA packages; 36 V VWM avoids false triggering during normal 12 V rail ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | DO-214AC package; 36 V VWM; 58.1 V VC; lower PPPM (400 W); non-AEC-Q101 | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and surge rating requirements |
| 1.5KE36A (ON Semiconductor) | DO-201AD axial lead; 36 V VWM; 58.1 V VC; 1500 W PPPM; through-hole only | Requires manual or wave-solder assembly; incompatible with high-density SMT layouts | Choose for legacy board redesigns or prototyping where reflow compatibility is not required |
Compared with SMAJ36A-E3/5A and 1.5KE36A, the SMPC36AN-M3/I uniquely combines AEC-Q101 qualification, 1500 W surge rating, and ultra-low 1.1 mm profile in a 3-terminal SMT package - making it the only option for space-constrained, automotive-grade, high-reliability transient suppression.

FAQ
What is the polarity configuration of the SMPC36AN-M3/I?
The SMPC36AN-M3/I is a unidirectional transient voltage suppressor. Its cathode is marked by a band on the package body, and the two anode terminals (Anode 1 and Anode 2) are internally connected. For proper operation, both anodes must be connected to the same potential - typically the protected line - while the cathode connects to ground or return path.
Does the SMPC36AN-M3/I meet automotive qualification standards?
Yes, the SMPC36AN-M3/I is AEC-Q101 qualified, as confirmed in Vishay document 89116. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and electrostatic discharge (HBM/MM), validating its use in automotive body electronics, infotainment, and ADAS subsystems.
What is the meaning of the "/I" suffix in SMPC36AN-M3/I?
The "/I" suffix denotes the preferred packaging format: 13-inch diameter plastic tape and reel, containing 6500 units. This format is optimized for high-volume automated SMT placement and aligns with industry-standard feeder compatibility for pick-and-place equipment.
How does the SMPC36AN-M3/I perform under elevated ambient temperatures?
The SMPC36AN-M3/I derates linearly above TA = 25 °C per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power (PPPM) drops to approximately 750 W, and its steady-state power dissipation (PD) falls to ~0.65 W - values critical for thermal design validation in enclosed enclosures or near heat sources.
Can the SMPC36AN-M3/I be used in bidirectional configurations?
No - the SMPC36AN-M3/I is strictly unidirectional. Bidirectional operation requires either two devices in series opposition or a dedicated bidirectional TVS such as the SMBJ36CA. Using SMPC36AN-M3/I in reverse bias beyond its specified IR limit risks permanent degradation due to uncontrolled avalanche conduction.
