Product details
Overview
SMC5K16CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 16 V stand-off voltage (VWM), and 26.0 V maximum clamping voltage at 192 A IPPM - deployed on power rails and signal lines of automotive ECUs and industrial motor drives.
For engineers reviewing the SMC5K16CA-M3/I datasheet, SMC5K16CA-M3/I pinout, SMC5K16CA-M3/I application, or SMC5K16CA-M3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 175 °C junction temperature rating, and compatibility with automated SMT assembly using J-STD-002-compliant matte tin leads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients induced by inductive switching or ESD events. Its bidirectional architecture enables symmetrical clamping across both polarities without polarity marking, supporting AC-coupled interfaces and differential bus lines.
It delivers 5000 W peak pulse power under 10/1000 μs waveform and sustains 40 kW under 8/20 μs lightning surge profile, with low incremental surge resistance ensuring minimal voltage overshoot during high-current surges up to 192 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - defines maximum continuous reverse operating voltage before clamping initiates; sets threshold for protection of 15 V nominal systems. |
| VBR (Breakdown Voltage) | 17.8–19.7 V at 1 mA - ensures reliable turn-on margin above VWM while avoiding false triggering during normal operation. |
| VC (Clamping Voltage) | 26.0 V at 192 A (10/1000 μs) - limits transient voltage seen by downstream ICs to safe levels compatible with 3.3 V/5 V/12 V logic and gate drivers. |
| PPPM | 5000 W (10/1000 μs) - supports robust protection against IEC 61000-4-5 Level 4 surges in industrial and automotive environments. |
| TJ max. | 175 °C - enables operation in under-hood automotive locations and high-temperature industrial enclosures without derating. |
| ESD Rating | ±30 kV HBM (IEC 61000-4-2) - provides immunity to human-body-model discharges common in manufacturing and field service handling. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional device with no cathode band; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals function identically; bidirectional conduction allows placement without orientation constraints on PCB. |
| Case (cathode side marking absent) | Thermal and mechanical interface | Exposed metal slug enhances thermal dissipation; requires adequate copper pour per JEDEC 51-2A footprint for RthJA = 90 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and HTRB testing - suitable for engine control, ADAS, and body electronics. |
| UL 497B recognized (E136766) | Meets safety requirements for telecom and industrial signal line protection, enabling use in certified end equipment without additional isolation. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns - eliminates bake requirements pre-assembly. |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance mandates for global OEMs and industrial customers; no brominated flame retardants in molding compound. |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 12 V battery-fed microcontroller power inputs in junction boxes and lighting modules. IC Role / Device Role / Timing Role: Shunt TVS diode clamping load-dump and jump-start transients before they reach LDOs or PMICs. Use Value: Withstands 5000 W surges and maintains 26.0 V clamping at 192 A, preventing brownout or latch-up in MCU power domains. |

IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across loop terminals to absorb fast transients without disrupting analog signaling. Use Value: Low clamping voltage (26.0 V) preserves loop integrity while ±30 kV HBM rating guards against operator-handling ESD events. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Surge suppression on Ethernet PHY power rails and MDI pairs in residential gateways and VoIP adapters. IC Role / Device Role / Timing Role: Primary-level TVS protecting PHY ICs and magnetics from lightning-induced surges per IEC 61000-4-5.

Use Value: Sub-nanosecond response time and 175 °C TJ rating ensure stable clamping during repeated motor commutation cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller footprint), same VWM (16 V), higher VC (26.5 V at 12.9 A) | Targeted for space-constrained consumer electronics; insufficient for automotive load-dump or industrial lightning surges | Select only when surge energy is limited to <100 mJ and board area is critical; not AEC-Q101 qualified. |
| 1.5KE16CA (ON Semiconductor) | Higher VBR (17.8–19.7 V), same VWM (16 V), identical PPPM (5000 W), but DO-201 package (through-hole) | Requires manual or wave soldering; unsuitable for fully automated SMT production lines | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs production efficiency. |
Compared with SMAJ16CA-E3/5A and 1.5KE16CA, the SMC5K16CA-M3/I uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 5000 W surge handling - making it the only option validated for high-reliability automotive SMT power rail protection.

FAQ
What is the clamping voltage of the SMC5K16CA-M3/I at its rated peak pulse current?
The SMC5K16CA-M3/I has a maximum clamping voltage (VC) of 26.0 V at 192 A peak pulse current under the 10/1000 μs waveform. This value is measured per Fig. 3 in the Vishay datasheet (Doc. #87024) and ensures downstream components see limited overvoltage during standardized surge events.
Is the SMC5K16CA-M3/I suitable for automotive applications?
Yes, the SMC5K16CA-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 systems including engine control modules, body control units, and ADAS sensor interfaces.
Does the SMC5K16CA-M3/I have polarity markings on the package?
No, the SMC5K16CA-M3/I is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows installation in either orientation on the PCB, simplifying layout and reducing assembly errors.
What is the thermal resistance of the SMC5K16CA-M3/I in standard mounting conditions?
The SMC5K16CA-M3/I has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on an FR4 PCB with the standard JEDEC 51-2A footprint, and a junction-to-mount thermal resistance (RthJM) of 4.0 °C/W per JEDEC 51-14 TDIM method.
How does the SMC5K16CA-M3/I compare to the SMC5K16A variant?
The SMC5K16CA-M3/I is bidirectional (CA suffix), whereas SMC5K16A is unidirectional (A suffix). The CA version clamps transients of either polarity, essential for AC-coupled or floating signal lines; the unidirectional variant requires correct polarity alignment and offers slightly lower leakage at VWM.
