Product details
Overview
SMPC36AN-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for clamping inductive switching transients and ESD events on power rails and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), 58.1 V maximum clamping voltage at 25.8 A IPPM, and operates within -55 °C to +150 °C junction temperature range.
For engineers reviewing the SMPC36AN-M3/H datasheet, SMPC36AN-M3/H pinout, SMPC36AN-M3/H application, or SMPC36AN-M3/H equivalent, this device is selected for high-energy surge protection in automotive sensor interfaces, industrial I/O modules, DC-DC converter input rails, and telecom line-card power supplies where low-profile SMT placement and AEC-Q101-compatibility are critical.
Technical Context
The SMPC36AN-M3/H employs an avalanche diode structure optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of fast-rising transients such as ISO 7637-2 pulse 1/2a and IEC 61000-4-5 surge waveforms. Its unidirectional polarity supports DC-biased rail protection with cathode-to-rail configuration.
Mounted on FR4 PCB with 2 oz copper, it delivers 1.25 W steady-state power dissipation at 25 °C ambient and exhibits RθJA ≤ 100 °C/W and RθJM ≤ 3 °C/W - critical for thermal management in compact, sealed enclosures. The TO-277A (SMPC) package enables dual-anode/cathode terminal layout for symmetric current sharing in high-surge applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 48 V nominal systems. |
| VBR min/max | 40.0 / 44.2 V at 1.0 mA - Confirmed breakdown threshold ensures reliable turn-on before system overvoltage damage occurs. |
| VC @ IPPM | 58.1 V at 25.8 A - Clamping voltage under 10/1000 μs surge; limits downstream IC stress to <60 V during 1500 W transient events. |
| PPPM | 1500 W - Peak pulse power rating per JEDEC-standard waveform; validates robustness against automotive load-dump surges. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |

| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
SMPC36AN-M3/H uses the SMPC (TO-277A) package: a 3-terminal surface-mount case with 1.1 mm typical height, UL 94 V-0 molding compound, and cathode band marking. Terminals are matte tin-plated for solderability per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 & Anode 2 | Parallel-connected anodes | Enable higher surge current handling via dual-path conduction; reduces thermal stress during repetitive transients. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC I/O Module |
|---|---|
Use Scenario: Protecting CAN/LIN transceivers and analog sensor front-ends (e.g., pressure, temperature) from load-dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor supply rail and ground, clamping positive surges before they reach sensitive analog front-end ICs. Use Value: Maintains signal integrity and prevents latch-up in 3.3 V/5 V sensor ICs by limiting rail voltage to ≤58.1 V during 1500 W pulses. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers exposed to inductive kickback from solenoids and relays. IC Role / Device Role / Timing Role: Primary surge clamp on field-side 24 V input terminals, absorbing energy before it reaches optocoupler or MCU GPIO protection networks. Use Value: Enables >100,000 surge cycles without degradation due to low thermal resistance (RθJM ≤ 3 °C/W) and robust junction design. |
| Telecom Line Card Power Supply | DC-DC Converter Input Stage |
Use Scenario: Protecting primary-side MOSFETs and controller ICs in 48 V telecom rectifier modules subjected to lightning-induced surges on AC/DC input stages. IC Role / Device Role / Timing Role: Secondary-level TVS across bulk capacitor input, triggered after MOV/GDT primary protection to limit residual clamping voltage. Use Value: Reduces peak voltage seen by downstream components to 58.1 V - well below 65 V MOSFET VDSS ratings - preventing avalanche failure. |
Use Scenario: Input rail protection for isolated 48 V → 12 V DC-DC converters in server power distribution units (PDUs). IC Role / Device Role / Timing Role: Fast-response clamping device placed upstream of input filter capacitors to absorb high-di/dt transients before LC filtering attenuates them. Use Value: Achieves sub-1 ns response time and 1500 W pulse handling, ensuring converter ICs survive repeated 10/1000 μs surges without derating. |
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; lower PPPM (400 W); single-anode; RθJA ≈ 150 °C/W. | Limited to lower-energy transients; unsuitable for automotive load-dump or telecom surge standards. | Select SMAJ36A-E3/5A only for cost-sensitive, non-automotive applications with <500 W surge requirements. |
| SMCJ36A-M3/86A (Vishay) | SMC (DO-214AB) package; same 1500 W PPPM; single-anode; 2.5 mm height; higher RθJA (120 °C/W). | Compatible for same surge levels but occupies more board area and has reduced thermal performance in confined spaces. | Choose SMCJ36A-M3/86A when board space allows and lower profile is not required; avoid in thermally constrained automotive modules. |
Compared with SMAJ36A-E3/5A and SMCJ36A-M3/86A, the SMPC36AN-M3/H delivers identical 1500 W surge capability in a 1.1 mm profile with dual-anode architecture and AEC-Q101 qualification - making it the only option among the three validated for under-hood automotive deployment with minimal footprint impact.

FAQ
What is the clamping voltage of SMPC36AN-M3/H at its rated peak pulse current?
The SMPC36AN-M3/H has a maximum clamping voltage (VC) of 58.1 V at 25.8 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during high-energy transients. The clamping behavior is consistent across production lots and verified per JEDEC test methods in the official Vishay datasheet 89116.
Is SMPC36AN-M3/H AEC-Q101 qualified?
Yes, SMPC36AN-M3/H is AEC-Q101 qualified - explicitly confirmed in the Vishay ordering information table and "Mechanical Data" section of datasheet 89116. The "AN" suffix denotes AEC-Q101 qualification, and the "HM3" variant (e.g., SMPC36ANHM3/H) is the automotive-grade version. SMPC36AN-M3/H itself carries the AN suffix and meets all stress tests including HTGB, TCT, and H3TRB.
What does the "H" suffix mean in SMPC36AN-M3/H?
The "H" suffix in SMPC36AN-M3/H specifies the preferred package code for 7-inch plastic tape-and-reel delivery, containing 1500 units per reel. It does not affect electrical or thermal specifications - all SMPC36AN-M3 variants (H, I, /86A, /87A) share identical electrical characteristics and TO-277A package dimensions per the Vishay datasheet.
How does the dual-anode configuration of SMPC36AN-M3/H improve surge performance?
The dual-anode (Anode 1 + Anode 2) configuration in SMPC36AN-M3/H provides parallel current paths during transient conduction, reducing effective incremental surge resistance and distributing thermal load across two bond wires and die regions. This improves reliability under repetitive surges and lowers localized heating versus single-anode equivalents like SMCJ36A-M3/86A.
Can SMPC36AN-M3/H replace SMAJ36A in existing designs?
No - SMPC36AN-M3/H is not a drop-in replacement for SMAJ36A due to different package (TO-277A vs. DO-214AC), pinout (3-terminal dual-anode vs. 2-terminal), and thermal characteristics. Layout redesign is required. However, its superior 1500 W rating, lower profile, and AEC-Q101 qualification make it a strategic upgrade for next-generation designs targeting automotive or high-reliability industrial use.
