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 high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 22 V stand-off voltage, and 35.5 V clamping voltage at 84.5 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom systems against lightning and inductive switching transients.
For engineers reviewing the 3.0C22CA-M3 datasheet, 3.0C22CA-M3 pinout, 3.0C22CA-M3 application, or 3.0C22CA-M3 equivalent, this page delivers verified electrical parameters, JEDEC-compliant thermal data, IEC 61000-4-2 ESD immunity (30 kV contact/air), and precise SMC package mechanical dimensions - all critical for layout validation and reliability assurance in high-surge environments.
Technical Context
This TVS diode operates bidirectionally with a breakdown voltage range of 24.4–26.9 V at 1 mA test current and clamps to ≤35.5 V under 84.5 A (10/1000 μs). Its low incremental surge resistance and fast response time ensure minimal overvoltage exposure during transient events.
It meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Junction temperature range spans −55 °C to +175 °C, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum reverse stand-off voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR min/max | 24.4 V / 26.9 V at 1 mA - Confirmed breakdown range ensures predictable turn-on behavior across production lot |
| VC @ IPPM | 35.5 V at 84.5 A (10/1000 μs) - Clamping voltage directly limits protected circuit stress during worst-case surge |
| PPPM | 3000 W (10/1000 μs) - Sustains high-energy transients without failure; enables robust front-end protection |
| IPPM | 84.5 A (10/1000 μs) - Peak surge current handling capacity validated per ANSI/IEEE C62.35 |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact & air) - Provides system-level electrostatic discharge immunity without external shielding |
| TJ max | +175 °C - Enables reliable operation in high-ambient industrial environments including motor drives and power supplies |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1, 260 °C reflow capable. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); cathode band marking absent on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (during positive half-cycle) | Conducts surge energy to ground when voltage exceeds VBR in either polarity; symmetric bidirectional structure |
| Cathode | Transient current sink (during negative half-cycle) | Same physical terminal as anode due to bidirectional construction; no polarity marking required |
Key Features
| Feature | Design Value |

| Low clamping ratio (VC/VWM = 1.61) | Minimizes overvoltage overshoot relative to working voltage - critical for 24 V industrial bus protection |
| UL 94 V-0 molding compound | Ensures flame-retardant PCB mounting in safety-critical enclosures including DIN-rail power supplies |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under thermal cycling - essential for automotive-qualified industrial deployments |
Applications
| Industrial Motor Drives | Telecom Line Interface |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensors in variable-frequency drives exposed to inductive kickback from 3-phase motors. IC Role / Device Role / Timing Role: Primary transient shunt device placed across DC bus or IGBT gate-source terminals. Use Value: Limits voltage spikes to ≤35.5 V during 84.5 A commutation events, preventing gate oxide rupture and false triggering. | Use Scenario: Surge suppression on POTS or xDSL line cards subjected to lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Bidirectional shunt clamp on tip/ring pair upstream of line transceiver ICs. Use Value: Maintains signal integrity by clamping 8/20 μs surges up to 30 kW while preserving <1.0 μA leakage at 22 V. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Input protection for LIN/CAN node power rails in battery-connected ECUs subject to load dump and jump-start transients. IC Role / Device Role / Timing Role: Secondary overvoltage clamp after primary TVS or fuse, absorbing residual energy not diverted upstream. Use Value: Withstands 30 kV ESD per IEC 61000-4-2 and operates reliably from −40 °C to +125 °C ambient. | Use Scenario: Protection of analog outputs (4–20 mA) and digital I/O (RS-485) in PLC analog modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Point-of-entry TVS on terminal block side of isolation barrier. Use Value: Clamps 10/1000 μs surges to 35.5 V while maintaining 1.0 μA max reverse leakage at 22 V - avoids signal offset errors. |
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 surges; not rated for 30 kW (8/20 μs) or 30 kV ESD | Select when space-constrained and surge threat level is limited to IEC 61000-4-4 (EFT), not lightning. |
| SMCJ22A | Unidirectional, identical SMC package and PPPM (3000 W), but requires polarity-aware layout | Applicable only where circuit ground reference is fixed and reverse conduction must be blocked | Choose only if system architecture mandates unidirectional clamping and polarity is strictly controlled. |
Compared with SMBJ22CA and SMCJ22A, the 3.0C22CA-M3 uniquely combines bidirectional operation, 3000 W rating, 30 kV ESD immunity, and SMC package thermal performance - making it optimal for high-reliability industrial interfaces where polarity uncertainty and surge severity coexist.

FAQ
What is the clamping voltage of the 3.0C22CA-M3 under a 10/1000 μs surge?
The 3.0C22CA-M3 clamps to a maximum of 35.5 V when subjected to its rated peak pulse current of 84.5 A with a 10/1000 μs waveform. This value is guaranteed per the datasheet's Electrical Characteristics table and reflects worst-case device behavior at TA = 25 °C. The clamping voltage ensures downstream ICs and MOSFETs remain within safe operating voltage limits during surge events.
Is the 3.0C22CA-M3 suitable for automotive applications?
Yes, the 3.0C22CA-M3 is qualified for automotive use in body electronics and powertrain auxiliary circuits. It operates across −55 °C to +175 °C junction temperature, passes JESD 201 Class 2 whisker testing, and withstands 30 kV ESD per IEC 61000-4-2 - meeting key requirements for under-hood and chassis-mounted modules. However, AEC-Q200 qualification must be confirmed per specific manufacturer lot documentation.
Does the 3.0C22CA-M3 have polarity markings on the package?
No, the 3.0C22CA-M3 does not feature polarity markings because it is a bidirectional TVS diode. Its symmetrical internal structure allows it to clamp voltage transients of either polarity equally, eliminating the need for orientation-specific placement on PCBs. This simplifies layout and reduces assembly error risk in high-volume manufacturing.
What is the thermal resistance from junction to ambient for the 3.0C22CA-M3?
The 3.0C22CA-M3 has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A. This value assumes a 2 oz. copper footprint matching the recommended pad layout. For thermal design, this means a 1 W dissipation raises junction temperature by ~90 °C above ambient - critical for derating during repetitive surge conditions.
Can the 3.0C22CA-M3 replace the 3.0C20CA-M3 in an existing design?
Yes, the 3.0C22CA-M3 can replace the 3.0C20CA-M3 in most cases, as both share identical SMC package, bidirectional configuration, and 3000 W rating. The 3.0C22CA-M3 offers higher VWM (22 V vs. 20 V) and slightly higher VBR (24.4–26.9 V vs. 22.2–24.5 V), providing improved noise margin in 24 V systems. Verify that the increased clamping voltage (35.5 V vs. 32.4 V) remains compatible with downstream device absolute maximum ratings.
