Product details
Overview
SMC5K36A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 40.0–44.2 V breakdown voltage, and 58.1 V maximum clamping voltage at 86.1 A. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K36A-M3/I datasheet, SMC5K36A-M3/I pinout, SMC5K36A-M3/I application, or SMC5K36A-M3/I equivalent, this device delivers AEC-Q101 qualification (industrial grade only per note), 30 kV ESD immunity per IEC 61000-4-2, and UL 497B safety recognition - critical for robust overvoltage design in automotive ECUs and industrial motor drives.
Technical Context
This TVS diode operates as a unidirectional clamping device, activated when reverse voltage exceeds its 40.0–44.2 V breakdown threshold. Its low incremental surge resistance and fast response time ensure effective suppression of 10/1000 μs and 8/20 μs transients induced by inductive switching or lightning surges.
Thermal performance is defined by RthJA = 90 °C/W and RthJM = 4.0 °C/W, supporting operation up to +150 °C junction temperature. The SMC (DO-214AB) package enables high-power dissipation while meeting MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 40.0–44.2 V at 1.0 mA test current - defines precise conduction onset for reliable overvoltage triggering |
| Stand-off Voltage VWM | 36 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| Peak Pulse Power PPPM | 5000 W (10/1000 μs) - sustains high-energy transients without failure in automotive load-dump scenarios |
| Clamping Voltage VC | 58.1 V at 86.1 A (10/1000 μs) - limits downstream voltage stress to safe levels during surge events |
| Junction Temperature Range | −55 °C to +150 °C - supports under-hood automotive and industrial ambient conditions |
| ESD Immunity | 30 kV contact/air discharge (IEC 61000-4-2) - protects against human-body-model electrostatic events |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 3.20 mm × 7.11 mm footprint and 2.06 mm height |
Pinout & Package
SMC5K36A-M3/I uses the standard SMC (DO-214AB) package: two-terminal, unidirectional device with cathode indicated by a color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Same SMC package, 36 V VWM, but lower PPPM (400 W) and higher VC (58.1 V @ 68.9 A) | Suitable for lower-energy transients; not rated for automotive load dump | Select SMC5K36A-M3/I when 5000 W surge handling and AEC-Q101 qualification are required |
| ON Semiconductor 1.5SMC36A | Identical electrical specs and SMC package; same VBR, VC, and PPPM; halogen-free, RoHS-compliant | Drop-in alternative with identical footprint and performance; qualified to AEC-Q101 for automotive | Choose based on supply chain availability and qualification documentation preference |
Compared with SMAJ36A and 1.5SMC36A, the SMC5K36A-M3/I provides the highest energy-handling capability (5000 W) among SMC-form-factor 36 V TVS devices and is explicitly validated for industrial-grade use per Vishay's datasheet note - making it optimal for demanding 24 V system protection where sustained surge robustness is critical.

FAQ
What is the breakdown voltage range of the SMC5K36A-M3/I?
The SMC5K36A-M3/I has a guaranteed breakdown voltage (VBR) range of 40.0 V to 44.2 V at 1.0 mA test current, as specified in the Vishay datasheet revision 09-Jan-2024. This tight tolerance ensures predictable clamping behavior across temperature and production lots, and directly supports design margining for 36 V nominal systems. The SMC5K36A-M3/I maintains this specification under standard test conditions (TA = 25 °C).
Is the SMC5K36A-M3/I AEC-Q101 qualified?
No, the SMC5K36A-M3/I is not AEC-Q101 qualified. Per the Vishay datasheet, AEC-Q101 qualification applies only to SMC5K10A through SMC5K20A with HM3 suffix (e.g., SMC5K20AHM3). The SMC5K36A-M3/I is designated for industrial-grade applications only, as explicitly stated in the "Note" section on page 1. The SMC5K36A-M3/I retains all other key specifications including UL 497B recognition and 30 kV ESD immunity.
What does the "-M3/I" suffix indicate in SMC5K36A-M3/I?
The "-M3" suffix denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while "/I" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3500 units. This differs from "/H", which uses 7-inch reels with 850-unit quantities. The SMC5K36A-M3/I is fully compatible with standard SMT pick-and-place equipment using the SMC (DO-214AB) footprint.
What is the maximum clamping voltage of the SMC5K36A-M3/I at rated peak pulse current?
The SMC5K36A-M3/I has a maximum clamping voltage (VC) of 58.1 V at 86.1 A peak pulse current under the 10/1000 μs waveform condition. This value is measured per Figure 3 in the datasheet and represents the upper limit of voltage seen by protected circuitry during worst-case surge events. The SMC5K36A-M3/I also achieves 76.0 V clamping at 526 A under the 8/20 μs waveform, confirming robust performance across transient profiles.
Can the SMC5K36A-M3/I be used in place of SMC5K36A-M3/H?
Yes, the SMC5K36A-M3/I and SMC5K36A-M3/H are electrically and mechanically identical - differing only in packaging format (13″ vs. 7″ tape-and-reel) and unit quantity (3500 vs. 850). Both share identical electrical characteristics, thermal ratings, and material compliance (halogen-free, RoHS). The SMC5K36A-M3/I is functionally interchangeable with SMC5K36A-M3/H in PCB layout and circuit design, requiring no schematic or footprint changes.
