Product details
Overview
SMC5K36CA-M3/H from Vishay General Semiconductor is a bidirectional 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), 58.1 V clamping voltage at 86.1 A, and 36 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against lightning and inductive switching transients.
For engineers reviewing the SMC5K36CA-M3/H datasheet, SMC5K36CA-M3/H pinout, SMC5K36CA-M3/H application, or SMC5K36CA-M3/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance values, clamping behavior under 10/1000 μs and 8/20 μs waveforms, and real-world use context for ESD-hardened designs requiring UL 497B recognition and MSL Level 1 handling.
Technical Context
This TVS diode operates bidirectionally with a breakdown voltage range of 40.0–44.2 V at 1.0 mA test current and maintains a maximum reverse leakage of 1.0 μA at 36 V stand-off voltage. Its low incremental surge resistance enables stable clamping during fast transients, while the 175 °C maximum junction temperature supports operation in under-hood automotive environments.
The device meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air), complies with JESD201 Class 2 whisker testing, and achieves thermal resistance of 90 °C/W (junction-to-ambient) and 4.0 °C/W (junction-to-mount) on standard FR4 PCBs - critical for sustained surge duty cycles in industrial motor drives and telecom power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 5000 W - sustains 86.1 A transient current without failure in typical 1000 μs surge events |
| Clamping Voltage VC | 58.1 V at 86.1 A - limits downstream voltage stress to safe levels for 3.3 V/5 V/12 V logic and gate drivers |
| Stand-off Voltage VWM | 36 V - ensures no conduction during normal operation up to rated DC bus voltage |
| Breakdown Voltage VBR | 40.0–44.2 V at 1.0 mA - defines precise turn-on threshold for predictable overvoltage triggering |
| Junction Temperature Range | –55 °C to +175 °C - enables deployment in engine control units and industrial inverters without derating |
| Thermal Resistance RthJA | 90 °C/W - determines required copper area and airflow for thermal management on 2 oz. FR4 |
| ESD Rating (IEC 61000-4-2) | 30 kV contact/air - exceeds automotive EMC requirements for infotainment and ADAS sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (DO-214AC), same VWM/VBR range but reduced surge capacity | Suitable only for low-energy signal-line protection; not rated for 8/20 μs lightning surges | Select when board space is constrained and peak currents remain below 12 A |
| 1.5KE36CA (ON Semiconductor) | Through-hole DO-201 package, 1500 W PPPM (10/1000 μs), higher clamping voltage (60.5 V at 24.9 A) | Limited to non-automotive industrial PCBs where reflow compatibility is not required | Choose for legacy through-hole designs needing cost-effective replacement with moderate surge margin |
Compared with SMAJ36CA-E3/5A and 1.5KE36CA, the SMC5K36CA-M3/H delivers 12.5× higher peak pulse power in surface-mount form, AEC-Q101 qualification for automotive use, and tighter clamping performance - making it the preferred choice for next-generation ECU, EV charger, and industrial automation designs demanding robust, reflow-ready surge immunity.

FAQ
What is the maximum clamping voltage of the SMC5K36CA-M3/H under a 10/1000 μs surge?
The SMC5K36CA-M3/H has a maximum clamping voltage of 58.1 V at 86.1 A under a 10/1000 μs waveform. This value is measured per Fig. 3 in Vishay document 87024 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMC5K36CA-M3/H maintains this clamping performance across its full operating temperature range.
Is the SMC5K36CA-M3/H qualified for automotive applications?
Yes, the SMC5K36CA-M3/H is AEC-Q101 qualified, as confirmed in the "Ratings and Characteristics Curves" section of Vishay document 87024. This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, validating its suitability for under-hood and chassis-mounted automotive systems. The SMC5K36CA-M3/H carries the HM3 suffix variant for full AEC-Q101 compliance.
What does the "-M3/H" suffix indicate in SMC5K36CA-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant, industrial-grade construction with JESD201 Class 2 whisker resistance; "/H" specifies packaging in 7-inch plastic tape and reel with 850 units per reel. This ordering code aligns with Vishay's preferred package code table in document 87024 and confirms moisture sensitivity level (MSL) 1 rating for lead-free reflow compatibility.
Does the SMC5K36CA-M3/H have UL safety certification?
Yes, the SMC5K36CA-M3/H holds UL 497B recognition with file number E136766, as stated in the "Features" section of Vishay document 87024. This certification validates its use in telecommunications and industrial equipment requiring third-party safety approval for transient protection components. The SMC5K36CA-M3/H meets all applicable dielectric strength and flammability (UL 94 V-0) requirements.
What is the thermal resistance junction-to-ambient for the SMC5K36CA-M3/H?
The thermal resistance junction-to-ambient (RthJA) for the SMC5K36CA-M3/H is 90 °C/W, measured per JEDEC 51-2A on a standard FR4 PCB with 2 oz. copper. This value is critical for calculating allowable power dissipation during repetitive surge events and must be used with the 175 °C maximum junction temperature to determine safe operating margins. The SMC5K36CA-M3/H also features RthJM = 4.0 °C/W for heatsink-coupled mounting.
