Product details
Overview
3.0C22CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 22 V stand-off voltage (VWM), 24.4–26.9 V breakdown voltage (VBR), 35.5 V clamping voltage (VC) at 84.5 A peak pulse current (IPPM), and 3000 W peak pulse power (10/1000 μs). It is used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the 3.0C22CA-M3 datasheet, 3.0C22CA-M3 pinout, 3.0C22CA-M3 application, or 3.0C22CA-M3 equivalent, key selection criteria include its bidirectional polarity, 175 °C max junction temperature, MSL Level 1 rating, 30 kV ESD immunity per IEC 61000-4-2, and compatibility with automated SMT assembly using matte tin-plated leads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that responds within picoseconds to transient overvoltages induced by inductive switching or lightning surges. Its low incremental surge resistance and fast response time ensure minimal overshoot during clamping events.
The device is rated for 3000 W peak pulse power under 10/1000 μs waveform and 30 kW under 8/20 μs waveform, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W - enabling robust thermal performance in high-density PCB layouts with standard FR4 mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 24.4 V / 26.9 V - guaranteed breakdown range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 35.5 V at 84.5 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 3000 W - peak pulse power handling capability under standard 10/1000 μs waveform |
| TJ max | +175 °C - maximum junction temperature, supporting operation in harsh industrial environments |
| ESD Rating | ±30 kV - human-body-model contact and air discharge immunity per IEC 61000-4-2 |
| Polarity | Bidirectional - symmetric clamping for AC or dual-polarity DC lines without orientation dependency |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink (bidirectional) | No polarity marking on bidirectional types; terminals are functionally symmetric for AC clamping |
| Anode | Transient current source (bidirectional) | Both terminals conduct equally during positive or negative transients - no directional installation required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 3000 W peak pulse power (10/1000 μs) | Supports high-energy surge suppression in motor drives and power supply inputs |
| 30 kV ESD immunity (IEC 61000-4-2) | Meets stringent electrostatic discharge requirements for exposed interfaces in consumer and industrial systems |
| MSL Level 1, 260 °C reflow compatible | Allows direct placement into standard lead-free SMT reflow profiles without moisture sensitivity risk |
| Low clamping voltage (35.5 V @ 84.5 A) | Minimizes voltage overshoot across protected ICs, reducing risk of latch-up or gate oxide damage |
Applications
| Industrial Motor Drive Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: Suppresses inductive kickback from relay coils and brushed DC motors in PLC I/O modules. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed across coil terminals or MOSFET drain-source to limit flyback spikes. Use Value: Prevents >100 V transients from exceeding 35.5 V at the protected node, ensuring reliable operation of 24 V control logic. | Use Scenario: Protects Ethernet PHY or RS-485 transceivers from lightning-induced surges on outdoor data lines. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on differential pair inputs before signal conditioning circuitry. Use Value: Clamps 8/20 μs surges up to 622 A (8/20 μs) while maintaining <50 V differential swing across protected receivers. |
| Consumer Sensor Signal Line Protection | Computer Power Rail Clamp |
Use Scenario: Shields analog outputs of temperature/humidity sensors connected to microcontrollers in smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF at 0 V) bidirectional clamp on 3.3 V or 5 V sensor output lines. Use Value: Limits ESD events to ≤35.5 V without distorting small-signal analog waveforms due to fast sub-nanosecond response. | Use Scenario: Guards 12 V or 24 V DC input rails of embedded computing modules against load-dump transients. IC Role / Device Role / Timing Role: High-power TVS mounted directly at board edge connector to absorb energy before reaching DC-DC converters. Use Value: Handles 3000 W pulses without degradation, sustaining repeated 10/1000 μs surges while maintaining VWM = 22 V stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | Lower PPPM (600 W), same VWM (22 V), SMB package (smaller footprint, higher RthJA) | Suitable for lower-energy transients; not recommended for 3000 W surge environments | Select 3.0C22CA-M3 when 3000 W clamping capacity and thermal robustness are required |
| SMCJ22A | Unidirectional, same SMC package and VWM, but lacks bidirectional symmetry | Requires polarity-aware layout; unsuitable for AC or floating differential lines | Choose 3.0C22CA-M3 where bidirectional clamping and polarity-agnostic placement are mandatory |
Compared with SMBJ22CA and SMCJ22A, the 3.0C22CA-M3 delivers triple the peak pulse power in the same SMC footprint while enabling polarity-free placement - critical for protecting bidirectional communication buses and ungrounded sensor outputs without redesigning layout or adding orientation checks.

FAQ
What is the clamping voltage of the 3.0C22CA-M3 under a 10/1000 μs surge?
The 3.0C22CA-M3 has a maximum clamping voltage (VC) of 35.5 V at 84.5 A peak pulse current under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events, protecting downstream 24 V-rated ICs and MOSFETs from overvoltage stress.
Is the 3.0C22CA-M3 suitable for lead-free reflow soldering?
Yes, the 3.0C22CA-M3 is rated MSL Level 1 and qualified for peak reflow temperatures up to 260 °C per J-STD-020. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, making it fully compatible with standard lead-free SMT assembly processes without preconditioning.
Does the 3.0C22CA-M3 have polarity markings on the package?
No - the 3.0C22CA-M3 is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) case. Both terminals are functionally identical, allowing orientation-agnostic placement on PCBs, which simplifies layout and eliminates assembly errors related to cathode/anode orientation.
What is the maximum junction temperature rating for the 3.0C22CA-M3?
The 3.0C22CA-M3 has a maximum junction temperature (TJ max) of +175 °C, enabling reliable operation in high-temperature industrial environments such as motor control cabinets, outdoor telecom enclosures, and automotive under-hood applications where ambient temperatures exceed 100 °C.
How does the 3.0C22CA-M3 compare to the 3.0C20CA-M3 in terms of voltage ratings?
The 3.0C22CA-M3 has a higher stand-off voltage (VWM = 22 V) and breakdown range (VBR = 24.4–26.9 V) than the 3.0C20CA-M3 (VWM = 20 V, VBR = 22.2–24.5 V), making it better suited for 24 V nominal systems where tighter margin above operating voltage is needed to avoid leakage or premature conduction during normal operation.
