Product details
Overview
3.0C64CA-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), 103 V clamping voltage at 29.1 A, and 71.1–78.6 V breakdown voltage range. It protects MOSFETs, ICs, and sensor signal lines against lightning-induced transients and inductive switching surges in industrial and telecom systems.
For engineers reviewing the 3.0C64CA-M3 datasheet, 3.0C64CA-M3 pinout, 3.0C64CA-M3 application, or 3.0C64CA-M3 equivalent, this device delivers verified bidirectional clamping, MSL Level 1 moisture sensitivity, JESD201 Class 2 whisker resistance, and 30 kV ESD immunity per IEC 61000-4-2 - critical for robust front-end protection in high-reliability PCB designs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transient overvoltages exceeding its standoff voltage (VWM = 64 V). Its low incremental surge resistance ensures minimal voltage overshoot during 8/20 μs surges up to 224 A, while thermal resistance RthJM = 4.0 °C/W enables stable operation at junction temperatures up to +175 °C.
The device meets IEC 61000-4-2 (30 kV contact/air discharge) and is rated for 10/1000 μs waveform compliance per ANSI/IEEE C62.35. Its halogen-free, RoHS-compliant construction and matte tin-plated leads support lead-free reflow soldering per J-STD-002 and JESD22-B102.

| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
|
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and jump-start transients in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to divert surge current away from sensitive analog/digital interfaces.

Use Scenario: Shielding analog outputs (4–20 mA, 0–10 V) of pressure/temperature sensors from EFT and surge coupling in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF at 0 V) shunt protector on signal line to ground, preserving bandwidth and accuracy. Use Value: Clamps transients to 103 V while adding <0.5 pF parasitic capacitance at signal frequency, avoiding measurement drift or aliasing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), same VWM (64 V), SMB package (smaller footprint, higher RthJA = 110 °C/W) | Not suitable for 3000 W surge events; limited to lower-energy I/O or secondary protection | Select when board space is constrained and surge threat level is ≤600 W (10/1000 μs) |
| 1.5KE68CA | Higher VBR (75.6–83.6 V), axial-leaded DO-201 package, same PPPM (3000 W) | Requires through-hole mounting; incompatible with automated SMT assembly; less suitable for high-density layouts | Choose only for legacy through-hole designs where SMT is unavailable or thermal path to heatsink is prioritized |
Compared with SMBJ64CA and 1.5KE68CA, the 3.0C64CA-M3 uniquely combines 3000 W SMT capability, bidirectional symmetry, MSL Level 1 handling, and 30 kV ESD immunity - making it the optimal choice for new industrial and telecom designs requiring high-energy, surface-mount surge resilience.

FAQ
What is the clamping voltage of the 3.0C64CA-M3 at its rated peak pulse current?
The 3.0C64CA-M3 has a maximum clamping voltage (VC) of 103 V at 29.1 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The 3.0C64CA-M3 maintains this clamping performance across its full operating temperature range.
Is the 3.0C64CA-M3 suitable for bidirectional signal line protection?
Yes, the 3.0C64CA-M3 is explicitly designed as a bidirectional TVS diode, with symmetrical breakdown characteristics and no polarity marking on the SMC package. It provides identical clamping behavior for positive and negative transients, making it ideal for protecting AC-coupled interfaces, differential buses, or floating sensor outputs where voltage polarity reversal occurs.
Does the 3.0C64CA-M3 meet lead-free reflow requirements?
Yes, the 3.0C64CA-M3 features matte tin-plated leads qualified for lead-free reflow soldering per J-STD-002 and JESD22-B102. Its MSL Level 1 rating allows unlimited floor life and compatibility with standard Pb-free reflow profiles up to 260 °C peak temperature, eliminating pre-bake requirements in manufacturing.
What is the ESD withstand capability of the 3.0C64CA-M3?
The 3.0C64CA-M3 is rated for 30 kV ESD immunity per IEC 61000-4-2 in both contact and air discharge modes. This specification is verified per the manufacturer's test methodology and confirms the device's ability to absorb repeated electrostatic discharges without parameter shift or functional degradation - a key requirement for front-panel and connector-level protection.
How does the thermal performance of the 3.0C64CA-M3 compare to similar SMC-packaged TVS diodes?
The 3.0C64CA-M3 achieves a junction-to-mount thermal resistance (RthJM) of 4.0 °C/W, significantly lower than typical SMC TVS devices (often >6 °C/W), due to optimized die attach and thermal pad design. This enables higher sustained surge duty cycles and improved reliability in thermally constrained layouts - a verified characteristic confirmed in Vishay's thermal characterization data for the 3.0CxxCA-M3 series.
