Product details
Overview
SMPC36A-M3/86A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for clamping transient overvoltages on power and signal lines. It features a 36.0 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), 25.8 A peak pulse current (IPPM), and 58.1 V maximum clamping voltage (VC) under 10/1000 μs surge - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the SMPC36A-M3/86A datasheet, SMPC36A-M3/86A pinout, SMPC36A-M3/86A application, or SMPC36A-M3/86A equivalent, key selection criteria include unidirectional polarity, 1500 W surge capability, 58.1 V clamping performance at rated IPPM, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HM3 suffix variants.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds its specified VBR range (40.0–44.2 V). Its low incremental surge resistance and fast response time enable effective suppression of inductive switching transients and ESD events.
The SMPC36A-M3/86A uses a dual-anode/single-cathode configuration in the SMPC (TO-277A) package, where the cathode band denotes polarity. Thermal performance is characterized by RθJA ≤ 100 °C/W (FR4, 2 oz copper) and TJ max = 150 °C, supporting operation in high-reliability embedded power rails.
Key Specifications

|---|---|
| VWM | 36.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR @ IT = 1 mA | 40.0–44.2 V - guaranteed avalanche initiation range under standardized test current |
| VC @ IPPM | 58.1 V - clamped voltage during 10/1000 μs 25.8 A surge, defining protected circuit voltage ceiling |
| PPPM | 1500 W - peak transient power handling per JEDEC standard waveform, critical for surge margin |

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; same 1500 W PPPM but higher RθJA (150 °C/W); single-anode construction | Larger footprint and lower thermal efficiency limit use in high-density or thermally constrained layouts | Select when legacy DO-214AC footprint compatibility is required and board space permits larger thermal pad area |
| 1.5KE36A (ON Semiconductor) | DO-201AD axial leaded package; 36 V VWM; 1500 W PPPM; 60 V VC; not surface-mountable | Requires through-hole assembly and manual rework; unsuitable for automated SMT production | Choose only for prototyping, repair, or low-volume non-SMT applications where board real estate is not constrained |
Compared with SMAJ36A-E3/5A and 1.5KE36A, the SMPC36A-M3/86A offers superior thermal performance (RθJA ≤ 100 °C/W), smaller footprint, and dual-anode layout for improved current sharing - making it optimal for high-reliability, high-density SMT designs requiring repeatable surge immunity.

FAQ
What is the clamping voltage of SMPC36A-M3/86A under full-rated surge conditions?
The SMPC36A-M3/86A has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated 10/1000 μs peak pulse current of 25.8 A. This value is measured per JEDEC-standard test conditions and defines the upper voltage limit imposed on protected circuits during transient events - critical for ensuring downstream components like MCUs or gate drivers remain within safe operating limits.
Is SMPC36A-M3/86A qualified for automotive applications?
The SMPC36A-M3/86A itself carries the industrial-grade M3 suffix and is not AEC-Q101 qualified. However, Vishay offers the functionally identical SMPC36ANHM3 variant (with HM3 suffix) that is AEC-Q101 qualified and intended for automotive use. Engineers selecting SMPC36A-M3/86A for automotive designs must verify qualification status per ordering code and consult Vishay's official automotive product list for SMPC36ANHM3.
What does the /86A package code signify for SMPC36A-M3/86A?
The /86A suffix indicates a 7-inch diameter plastic tape-and-reel packaging format containing 1500 units per reel, compliant with EIA-481 standards. This packaging supports high-speed pick-and-place assembly and is optimized for standard SMT line feeders. The /86A code is distinct from /87A (13-inch reel, 6500 units) and does not affect electrical or thermal specifications of the SMPC36A-M3/86A device itself.
How does the dual-anode configuration of SMPC36A-M3/86A improve performance over single-anode TVS diodes?
The dual-anode (pins 1 & 2) structure of SMPC36A-M3/86A provides parallel current paths during surge events, lowering effective incremental resistance and distributing thermal stress across two bond wires and die regions. This results in more stable clamping behavior, reduced localized heating, and enhanced reliability under repetitive surge conditions compared to single-anode equivalents like SMAJ36A-E3/5A.
Can SMPC36A-M3/86A be used in bidirectional transient protection circuits?
No - SMPC36A-M3/86A is strictly unidirectional and must be used with correct polarity alignment (cathode to ground or reference rail). For bidirectional protection, two SMPC36A-M3/86A devices can be connected in series opposition (anode-to-anode), forming a symmetrical clamping pair capable of suppressing both positive and negative transients on AC or floating lines - a common practice in telecom -48 V systems.
