Product details
Overview
3.0C24CA-M3 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 3000 W peak pulse power (10/1000 μs), 24 V stand-off voltage, and 38.9 V clamping voltage at 581 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C24CA-M3 datasheet, 3.0C24CA-M3 pinout, 3.0C24CA-M3 application, or 3.0C24CA-M3 equivalent, key selection criteria include bidirectional clamping capability, 175 °C max junction temperature, IEC 61000-4-2 ±30 kV ESD immunity, low incremental surge resistance, and MSL Level 1 reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by transient overvoltage events. Its bidirectional structure enables symmetrical clamping on both polarities without polarity marking, and its silicon avalanche design delivers sub-nanosecond response time with stable breakdown between 26.7 V and 29.5 V at 1 mA test current.
The device sustains 3000 W peak pulse power under standardized 10/1000 μs waveform while maintaining 77.1 A maximum clamping current at 38.9 V - enabling robust protection of 24 V DC systems against inductive switching transients and lightning-induced surges per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 24 V nominal systems. |
| VBR min/max | 26.7 V / 29.5 V - Breakdown voltage range at 1 mA; ensures reliable triggering above system operating voltage with process tolerance. |
| VC @ IPPM | 38.9 V - Clamping voltage at 581 A peak pulse current; limits downstream voltage stress during surge events. |
| PPPM | 3000 W - Peak pulse power handling (10/1000 μs); supports high-energy transient suppression in industrial power supplies. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient environments such as motor drives and outdoor telecom enclosures. |
| ESD Rating | ±30 kV - Human body model (HBM) contact and air discharge per IEC 61000-4-2; provides board-level ESD hardening without external circuitry. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional, unmarked polarity, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.

|---|---|---|
| Cathode (K) | Transient current sink (bidirectional) | Acts as common terminal for both polarities; connects to protected line or ground reference depending on layout. |
| Anode (A) | Transient current source (bidirectional) | Paired with cathode to form symmetrical clamping path; no polarity marking required for bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|

| 3000 W peak pulse power | Supports MIL-STD-1275E and ISO 7637-2 Pulse 1/2/5a compliance in 24 V vehicle subsystems. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive gate drivers. |
| MSL Level 1 rating | Allows unlimited floor life and standard 260 °C reflow profile without baking, reducing manufacturing complexity. |
| Halogen-free & RoHS-compliant | Fulfills IPC-1752A material declaration requirements for industrial and medical end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Lower peak pulse power (600 W), same VWM/VC, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for 3000 W IEC 61000-4-5 compliance | Select when space-constrained and surge energy ≤600 W suffices |
| SMCJ24CA | Same SMC package, identical VWM/VC, but 1500 W PPPM (10/1000 μs) | Half the energy handling of 3.0C24CA-M3; requires derating in high-repetition surge environments | Choose for cost-sensitive designs where full 3000 W rating is not mandated |
Compared with SMBJ24CA and SMCJ24CA, the 3.0C24CA-M3 delivers double the pulse power of SMCJ24CA and five times that of SMBJ24CA in the same SMC footprint - making it the only option among the three qualified for high-energy 24 V industrial surge standards including IEC 61000-4-5 Level 4.

FAQ
What is the breakdown voltage range of the 3.0C24CA-M3?
The 3.0C24CA-M3 has a specified breakdown voltage (VBR) range of 26.7 V to 29.5 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ensures consistent avalanche initiation above the 24 V stand-off voltage while accommodating process variation across production lots.
Does the 3.0C24CA-M3 meet automotive surge standards?
Yes, the 3.0C24CA-M3 meets ISO 16750-2 Load Dump requirements when used with appropriate upstream impedance, and its 3000 W peak pulse power rating supports compliance with ISO 7637-2 Pulse 5a. Its 175 °C max junction temperature also aligns with under-hood automotive thermal requirements.
What is the clamping voltage of the 3.0C24CA-M3 at its rated peak pulse current?
The 3.0C24CA-M3 clamps to 38.9 V at its rated peak pulse current of 581 A under the 10/1000 μs waveform. This value is guaranteed per datasheet Table 1 and defines the maximum voltage imposed on protected circuitry during worst-case surge events.
Is the 3.0C24CA-M3 compatible with lead-free reflow soldering?
Yes, the 3.0C24CA-M3 carries the -M3 suffix indicating halogen-free, RoHS-compliant construction with matte tin-plated leads qualified for J-STD-002 solderability and MSL Level 1 handling - supporting standard Pb-free reflow profiles up to 260 °C peak temperature.
How does the 3.0C24CA-M3 differ from the SMCJ24CA in practical design use?
The 3.0C24CA-M3 delivers 3000 W peak pulse power versus 1500 W for SMCJ24CA - a critical difference in applications exposed to repeated high-energy transients like industrial motor drives. Both share the SMC package and 24 V stand-off, but only the 3.0C24CA-M3 maintains full specification margin under IEC 61000-4-5 Level 4 testing.
