Product details
Overview
SMC5K10CA-M3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features 11.1 V minimum breakdown voltage (VBR), 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 294 A (10/1000 μs), 5000 W peak pulse power rating, and AEC-Q101 qualification - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMC5K10CA-M3/H datasheet, SMC5K10CA-M3/H pinout, SMC5K10CA-M3/H application, or SMC5K10CA-M3/H equivalent, key selection criteria include clamping performance under 10/1000 μs surges, bidirectional polarity, thermal resistance (RthJA = 90 °C/W), MSL Level 1 moisture sensitivity, and UL 497B safety recognition.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients induced by inductive switching or lightning. Its silicon avalanche structure delivers low incremental surge resistance (typical <0.05 Ω) and stable clamping across -55 °C to +175 °C junction temperature range.
The device uses a symmetrical bidirectional design with no cathode band, enabling protection on AC lines or differential signal paths without polarity concerns. It meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air discharge) and is qualified per AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 11.1 V at 1.0 mA - ensures reliable avalanche conduction onset above normal operating voltage |
| VWM | 10 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 17.0 V at 294 A (10/1000 μs) - defines worst-case clamped voltage seen by protected IC or MOSFET |
| PPPM | 5000 W (10/1000 μs) - supports high-energy surge suppression in automotive load-dump scenarios |
| TJ max | +175 °C - enables placement near hot components (e.g., power converters, engine control units) |
| RthJA | 90 °C/W - determines thermal derating on standard FR4 PCB with 2 oz copper |
| ESD Rating | 30 kV HBM (contact/air) - exceeds IEC 61000-4-2 Level 4 for system-level ESD robustness |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller footprint), same VWM/VC but higher RthJA (150 °C/W) | Suitable for space-constrained consumer electronics where surge energy ≤400 W suffices | Select SMC5K10CA-M3/H when ≥5000 W surge handling or automotive AEC-Q101 is required |
| 1.5KE10CA (ON Semiconductor) | Higher VC (18.2 V), through-hole DO-201 package, same VWM, lower ESD rating (16 kV HBM) | Used in legacy industrial power supplies where board real estate allows axial leaded devices | Choose SMC5K10CA-M3/H for surface-mount assembly, tighter clamping, and automotive-grade reliability |
Compared with SMAJ10CA-E3/5A and 1.5KE10CA, the SMC5K10CA-M3/H delivers 12.5× higher peak pulse power in an SMT package with superior thermal dissipation (RthJA = 90 °C/W vs. 150 °C/W) and full AEC-Q101 validation - making it optimal for high-reliability automotive and industrial front-end protection.

FAQ
What is the clamping voltage of SMC5K10CA-M3/H at its rated peak pulse current?
The SMC5K10CA-M3/H has a maximum clamping voltage (VC) of 17.0 V at 294 A peak pulse current under the 10/1000 μs waveform condition. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 87024, Rev. 10-Sep-2024) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMC5K10CA-M3/H suitable for automotive applications?
Yes, the SMC5K10CA-M3/H is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its operating junction temperature range of -55 °C to +175 °C, MSL Level 1 rating, and compliance with ISO 7637-2 surge immunity requirements make it appropriate for protecting ECUs, body controllers, and sensor interfaces in passenger vehicles and commercial vehicles.
Does SMC5K10CA-M3/H have polarity markings on the package?
No, the SMC5K10CA-M3/H is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical internal structure allows either terminal to serve as anode or cathode depending on transient polarity - simplifying layout on AC-coupled or differential signal lines such as RS-485 or LIN bus.
What is the thermal resistance of SMC5K10CA-M3/H from junction to ambient?
The SMC5K10CA-M3/H has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB with 2 oz copper, per JEDEC 51-2A. This value is critical for calculating safe power derating above 25 °C ambient and must be verified using actual board layout and copper area in thermal simulations.
How does the SMC5K10CA-M3/H compare to unidirectional TVS diodes in protection design?
The SMC5K10CA-M3/H provides symmetrical clamping for both positive and negative transients, eliminating the need for dual-diode configurations in AC or bidirectional signal paths. Unlike unidirectional TVS diodes (e.g., SMC5K10A), it avoids forward-conduction issues on negative excursions and supports simplified PCB routing in differential interfaces like CAN FD or isolated sensor outputs.
