Product details
Overview
SMC5K16CA-M3/H 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), 17.8–19.7 V breakdown voltage, and 26.0 V clamping voltage at 192 A. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K16CA-M3/H datasheet, SMC5K16CA-M3/H pinout, SMC5K16CA-M3/H application, or SMC5K16CA-M3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 175 °C max junction temperature, and compatibility with 16 V nominal DC bus systems requiring robust ESD and lightning surge immunity.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by transient overvoltage events. Its bidirectional architecture enables symmetrical clamping above ±17.8 V, with low incremental surge resistance ensuring stable clamping under 192 A 10/1000 μs pulses and 1163 A 8/20 μs surges.
It features fast response time (<1 ns), meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air), and maintains thermal stability via RthJA = 90 °C/W and RthJM = 4.0 °C/W - enabling reliable operation in high-density PCB layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 17.8–19.7 V at 1.0 mA test current - defines precise turn-on threshold for overvoltage detection |
| Stand-off Voltage VWM | 16 V maximum - ensures no conduction during normal 16 V system operation |
| Clamping Voltage VC | 26.0 V at 192 A (10/1000 μs) - limits downstream voltage stress to safe levels during surge |
| Peak Pulse Power | 5000 W (10/1000 μs) - sustains high-energy transients without failure in automotive load-dump scenarios |
| Junction Temperature Range | –55 °C to +175 °C - supports under-hood and industrial environments without derating |
| ESD Immunity | 30 kV per IEC 61000-4-2 (HBM contact/air) - eliminates need for additional ESD front-end protection |
| AEC-Q101 Qualified | Yes - validated for automotive powertrain and body electronics applications per stress test requirements |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, M3 grade. Matte tin-plated leads, J-STD-002 solderable, MSL Level 1 (260 °C peak reflow).
| 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 |
|---|---|---|---|
| SMAJ16CA-E3/5A (Vishay) | Lower peak pulse power (400 W vs. 5000 W); SMA package (smaller footprint, higher RthJA) | Suitable for low-energy ESD-only protection; insufficient for load dump or lightning surges | Select SMC5K16CA-M3/H when system-level surge immunity (IEC 61000-4-5) or automotive load dump (ISO 7637-2) is required. |
| 1.5KE16CA (Littelfuse) | Same VWM/VBR range but through-hole DO-201 package; 5000 W rating retained | Requires through-hole assembly; less suitable for automated SMT production or space-constrained designs | Choose SMC5K16CA-M3/H for surface-mount manufacturing, higher thermal performance (RthJM = 4.0 °C/W), and AEC-Q101 qualification. |
Compared with SMAJ16CA-E3/5A and 1.5KE16CA, the SMC5K16CA-M3/H delivers superior surge handling in SMT format with automotive-grade reliability, making it optimal for high-reliability 16 V rail protection where board space, thermal management, and qualification rigor are critical.

FAQ
What is the clamping voltage of the SMC5K16CA-M3/H at its rated peak pulse current?
The SMC5K16CA-M3/H has a maximum clamping voltage (VC) of 26.0 V at 192 A peak pulse current under the standard 10/1000 μs waveform. This value is measured per Fig. 3 in the Vishay datasheet 87024 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMC5K16CA-M3/H maintains this clamping performance across its full operating temperature range.
Is the SMC5K16CA-M3/H suitable for automotive applications?
Yes, the SMC5K16CA-M3/H is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood and body electronics applications. Its 5000 W peak pulse power and bidirectional clamping support ISO 7637-2 load dump and ISO 16750-2 supply transient protection. The SMC5K16CA-M3/H is explicitly listed in Vishay's automotive-grade product documentation.
Does the SMC5K16CA-M3/H have polarity markings on the package?
No, the SMC5K16CA-M3/H is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMC (DO-214AB) package. Both terminals are electrically symmetric, allowing installation without orientation concern in AC-coupled or dual-polarity DC protection paths. This simplifies layout and reduces assembly errors compared to unidirectional variants.
What is the thermal resistance from junction to mounting pad for the SMC5K16CA-M3/H?
The SMC5K16CA-M3/H has a typical thermal resistance from junction to mounting pad (RthJM) of 4.0 °C/W, per JEDEC 51-14 TDIM testing. This low value enables effective heat dissipation into PCB copper pours, supporting repeated surge duty cycles without thermal runaway. The SMC5K16CA-M3/H achieves this performance using optimized die attach and leadframe design within the SMC package.
How does the SMC5K16CA-M3/H compare to standard ESD diodes like the USBLC6-2SC6?
The SMC5K16CA-M3/H is a high-energy TVS diode rated for 5000 W (10/1000 μs) and 40 kW (8/20 μs), whereas USBLC6-2SC6 is an ESD-only device rated for 3 A (8/20 μs) and 120 W peak. The SMC5K16CA-M3/H targets system-level surge events (lightning, load dump), not just human-body-model ESD. Its VWM = 16 V and VC = 26.0 V make it unsuitable as a direct replacement for low-voltage signal-line ESD protection.
