Product details
Overview
SMC5K10CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 5000 W peak pulse power (10/1000 μs), 11.1–12.3 V breakdown voltage at 1 mA, and 10 V stand-off voltage - designed to protect MOSFETs, ICs, and sensor signal lines against lightning-induced transients and inductive switching surges in automotive and industrial systems.
For engineers reviewing the SMC5K10CA-M3/I datasheet, SMC5K10CA-M3/I pinout, SMC5K10CA-M3/I application, or SMC5K10CA-M3/I equivalent, key selection criteria include clamping voltage (17.0 V at 294 A), bidirectional polarity, AEC-Q101 qualification, UL 497B recognition, and thermal resistance (RthJA = 90 °C/W) under JEDEC 51-2A mounting conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device with symmetrical avalanche breakdown behavior across both polarities. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of transient energy before downstream components experience overvoltage stress.
The device is characterized by two distinct pulse ratings: 5000 W (10/1000 μs) for general surge immunity and 40 kW (8/20 μs) for high-energy lightning surge compliance. It maintains stable operation from −55 °C to +175 °C junction temperature and meets MSL Level 1 reflow requirements with 260 °C peak soldering profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - defines reliable avalanche initiation threshold for bidirectional clamping |
| VWM | 10 V - maximum continuous reverse voltage before leakage exceeds 1 μA; sets safe operating margin below breakdown |
| VC @ IPPM | 17.0 V at 294 A (10/1000 μs) - actual clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 5000 W (10/1000 μs) - peak transient power handling capacity under standard surge waveform |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments without derating |
| RthJA | 90 °C/W - thermal resistance from junction to ambient on standard FR4 PCB; determines power dissipation limits in real layout |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no cathode band; matte tin-plated leads, halogen-free, RoHS-compliant, and qualified to AEC-Q101.
| 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 |
|---|---|---|---|
| SMBJ10CA-E3/52 | Lower peak pulse power (600 W vs. 5000 W); SMB (DO-214AA) package; same VWM/VBR range | Suitable for lower-energy ESD and board-level EFT, not for lightning or load-dump surges | Select SMC5K10CA-M3/I when surge current exceeds 100 A or system requires AEC-Q101/UL 497B compliance. |
| 1.5KE10CA | Higher power (1500 W), through-hole DO-201AE package; slower thermal response; no AEC-Q101 or UL recognition | Used in legacy industrial power supplies where reflow compatibility is not required | Choose SMC5K10CA-M3/I for SMT production, automotive qualification, and higher surge margin in compact layouts. |
Compared with SMBJ10CA-E3/52 and 1.5KE10CA, the SMC5K10CA-M3/I delivers 8.3× higher peak pulse power in an AEC-Q101-qualified SMT package with UL safety certification - making it the only option among the three validated for automotive power rail and telecom port protection requiring 40 kW surge capability.

FAQ
What is the clamping voltage of the SMC5K10CA-M3/I under a 10/1000 μs surge?
The SMC5K10CA-M3/I clamps to a maximum of 17.0 V when subjected to its rated peak pulse current of 294 A using the 10/1000 μs waveform. This value is measured per Fig. 3 in the Vishay datasheet 87024 and represents the upper limit of voltage imposed on protected circuitry during standardized surge testing. The SMC5K10CA-M3/I maintains this clamping performance across its full operating temperature range.
Is the SMC5K10CA-M3/I suitable for automotive applications?
Yes, the SMC5K10CA-M3/I is AEC-Q101 qualified and rated for operation from −55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive electronics. Its halogen-free, RoHS-compliant construction and MSL Level 1 reflow compatibility further support automated manufacturing in automotive supply chains. The SMC5K10CA-M3/I is explicitly listed in Vishay's AEC-Q101 qualified products table.
Does the SMC5K10CA-M3/I have polarity markings?
No, the SMC5K10CA-M3/I is a bidirectional TVS diode and carries no cathode band or polarity marking on its SMC (DO-214AB) package. Its symmetrical construction allows installation in either orientation on PCBs protecting AC signals, differential buses, or floating nodes. Polarity independence simplifies layout and eliminates orientation errors during automated placement of the SMC5K10CA-M3/I.
What is the junction-to-ambient thermal resistance of the SMC5K10CA-M3/I?
The SMC5K10CA-M3/I has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A test conditions. This value assumes a 2 oz. copper footprint matching the recommended pad layout in the datasheet. Effective heat dissipation of the SMC5K10CA-M3/I depends on adherence to this layout and adequate copper area around the terminals.
How does the SMC5K10CA-M3/I compare to unidirectional TVS diodes in circuit protection?
The SMC5K10CA-M3/I provides symmetrical clamping for both positive and negative transients, eliminating the need for dual-diode configurations in AC or bipolar signal paths. Unlike unidirectional TVS diodes, which conduct only in reverse bias, the SMC5K10CA-M3/I activates identically regardless of surge polarity - simplifying design for RS-485, CAN, or sensor bridge outputs. Its bidirectional behavior is intrinsic to the SMC5K10CA-M3/I's silicon structure, not external circuitry.
