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 range. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C64CA-M3 datasheet, 3.0C64CA-M3 pinout, 3.0C64CA-M3 application, or 3.0C64CA-M3 equivalent, key selection criteria include bidirectional clamping capability, 175 °C junction temperature rating, MSL Level 1 moisture sensitivity, and compliance with IEC 61000-4-2 (30 kV ESD).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive switching or lightning surges. Its low incremental surge resistance and fast response ensure minimal overvoltage exposure to downstream components.
It meets JEDEC J-STD-020 MSL Level 1, supports 260 °C lead-free reflow, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The halogen-free, RoHS-compliant -M3 suffix passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR Min/Max | 71.1 V / 78.6 V - defines reliable conduction onset under transient stress; ensures protection starts before damage threshold of 64 V-rated circuits |
| VWM | 64 V - maximum continuous reverse operating voltage; sets upper limit for safe DC bias without leakage degradation |
| VC @ IPPM | 103 V @ 29.1 A - clamping voltage during 10/1000 μs surge; determines worst-case overvoltage seen by protected device |
| PPPM | 3000 W - peak pulse power handling (10/1000 μs); enables robust protection against IEC 61000-4-5 line surges |
| TJ max | 175 °C - maximum junction temperature; supports operation in high-ambient industrial environments without derating |
| ESD Rating | 30 kV (HBM contact/air) - exceeds IEC 61000-4-2 Level 4; eliminates need for additional ESD stages on board |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with unmarked cathode/anode terminals. Dimensions per JEDEC DO-214AB standard: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H), with 3.20 mm minimum terminal length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (bidirectional) | Conducts surge current in either polarity; no polarity marking required on body |
| Cathode | Transient current sink (bidirectional) | Functions identically to anode; symmetric structure enables AC-line or data-line protection without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal paths (e.g., RS-485, PoE, Ethernet PHYs) without polarity concerns |
| 30 kW surge rating (8/20 μs) | Supports immunity to severe lightning-induced surges per IEC 61000-4-5; delivers 134 V clamping at 224 A |
| Low Rsurge | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), critical for protecting sensitive gate drivers and ADC inputs |
| MSL Level 1 | Allows unlimited floor life and standard reflow without baking; reduces manufacturing overhead in high-volume SMT lines |
| UL 94 V-0 molding | Ensures flame-retardant housing integrity during fault conditions, meeting IPC-CC-830B and end-equipment safety standards |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of IGBT gate driver inputs against voltage spikes from motor coil commutation and regenerative braking feedback. IC Role / Device Role / Timing Role: Shunt TVS placed directly across gate-source terminals to clamp transients below 20 V absolute maximum rating. Use Value: Prevents false triggering or oxide breakdown in gate drivers by limiting overvoltage to ≤103 V at 29.1 A surge, preserving system reliability over 100,000+ cycles. | Use Scenario: Surge suppression on -48 V DC telecom power distribution lines feeding remote radio units and base station controllers. IC Role / Device Role / Timing Role: Primary line-level protector upstream of DC/DC converters and PMICs, rated for repeated 3000 W pulses. Use Value: Maintains uninterrupted operation during lightning-induced surges (IEC 61000-4-5) by clamping to 103 V while dissipating 3000 W, avoiding brownouts or latch-up. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load dump and alternator ripple in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector interface to absorb ±100 V transients per ISO 7637-2 Pulse 5a. Use Value: Ensures functional safety compliance (ISO 26262 ASIL-B) by limiting transient exposure to <103 V, preventing MCU reset or communication failure. | Use Scenario: Shielding analog front-end inputs of pressure/temperature sensors in factory automation PLCs from EMI and relay-switching noise. IC Role / Device Role / Timing Role: Low-capacitance (typ. 35 pF at 0 V) shunt protector on 4–20 mA or 0–10 V signal lines. Use Value: Preserves signal integrity with <1 nA leakage at 64 V, enabling sub-mV measurement accuracy while surviving 30 kV ESD events. |
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/VBR range, SMB package (smaller footprint, higher thermal resistance) | Not suitable for 3000 W IEC 61000-4-5 line surges; limited to board-level ESD and low-energy transients | Select when space-constrained layouts prioritize size over surge energy handling |
| SMCJ64CA | Identical SMC package, same VWM/VBR, but rated for 1500 W PPPM (10/1000 μs) and lower clamping (93.6 V @ 16.1 A) | Acceptable for moderate-surge environments (e.g., consumer USB ports) but insufficient for industrial mains-connected equipment | Choose when cost optimization is critical and full 3000 W capability is not required |
Compared with SMBJ64CA and SMCJ64CA, the 3.0C64CA-M3 delivers double the surge energy capacity of SMCJ64CA and five times that of SMBJ64CA-enabling single-device compliance with IEC 61000-4-5 Class 3/4 in high-reliability industrial power interfaces.

FAQ
What is the breakdown voltage tolerance for 3.0C64CA-M3?
The 3.0C64CA-M3 has a specified breakdown voltage range of 71.1 V to 78.6 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 75 V midpoint. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable overvoltage protection design margins in 64 V systems.
Does 3.0C64CA-M3 require orientation during PCB placement?
No, the 3.0C64CA-M3 is a bidirectional TVS diode with symmetrical electrical characteristics and no polarity marking on the SMC package body. It can be mounted in either orientation on the PCB, simplifying layout and assembly for AC-coupled or differential signal protection such as RS-485 or CAN bus interfaces.
What is the maximum clamping voltage of 3.0C64CA-M3 under an 8/20 μs surge?
Under an 8/20 μs surge waveform, the 3.0C64CA-M3 clamps to 134 V at a peak current of 224 A. This value is specified in the Vishay datasheet (Document Number 98266, Rev. 09-Jan-2024) and reflects its capability to suppress high-energy lightning-induced transients per IEC 61000-4-5.
Is 3.0C64CA-M3 compatible with lead-free reflow processes?
Yes, the 3.0C64CA-M3 is qualified for lead-free reflow with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1 requirements. Its matte tin-plated terminals comply with J-STD-002 solderability standards, ensuring reliable wetting and joint formation without voiding or dewetting in standard SMT assembly lines.
How does the thermal resistance of 3.0C64CA-M3 affect its surge duty cycle?
The 3.0C64CA-M3 has RthJA = 90 °C/W and RthJM = 4.0 °C/W. Under repeated surge conditions, junction temperature rise must stay below 175 °C. With RthJM this low, heat transfers efficiently to the PCB copper, allowing higher duty-cycle operation when mounted on ≥2 oz. FR4 with adequate thermal pads-critical for applications like motor drive snubbers.
