Product details
Overview
3.0C75CA-M3/I 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), 121 V maximum clamping voltage at 24.8 A IPPM, and 75 V standoff voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C75CA-M3/I datasheet, 3.0C75CA-M3/I pinout, 3.0C75CA-M3/I application, or 3.0C75CA-M3/I equivalent, key selection criteria include bidirectional clamping behavior, 175 °C junction temperature rating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly using matte tin-plated leads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by transient overvoltage events. Its bidirectional architecture enables symmetric clamping above ±75 V standoff, with sub-nanosecond response time and low incremental surge resistance to minimize let-through energy during 8/20 μs (157 V @ 191 A) and 10/1000 μs surges.
It meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air), complies with UL 94 V-0 flammability, and is halogen-free, RoHS-compliant, and qualified per JESD 201 Class 2 whisker test - supporting reliability-critical industrial and telecom deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 83.3 V / 92.1 V - breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 121 V @ 24.8 A - clamping voltage under 10/1000 μs surge, limiting downstream voltage stress |
| PPPM | 3000 W - peak pulse power handling capability for 10/1000 μs waveform, critical for lightning/surge margin |
| TJ max | +175 °C - maximum junction temperature enabling operation in high-ambient industrial environments |
| ESD Rating | 30 kV HBM (contact/air) - ensures robustness against human-body-model electrostatic discharge events |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, dual-terminal, unmarked polarity for bidirectional operation. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (unmarked end) | Anode/Cathode terminal pair | Bidirectional conduction path - either terminal serves as anode or cathode depending on transient polarity |
| Anode (unmarked end) | Anode/Cathode terminal pair | No polarity marking required; symmetrical layout simplifies PCB routing and eliminates orientation errors in SMT placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity constraints |
| 3000 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line, 2 kV line-to-ground) in compact SMC footprint |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes let-through overvoltage during transients, reducing stress on protected MOSFETs and ICs |
| MSL Level 1, 260 °C reflow compatible | Allows standard lead-free reflow profiles without pre-baking, streamlining high-volume manufacturing |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and DC bus sensing circuits against inductive switching spikes in variable-frequency drives. IC Role / Device Role / Timing Role: Shunt TVS device clamping transient voltages induced by IGBT/MOSFET turn-off. Use Value: Limits voltage overshoot to ≤121 V during 24.8 A surges, preventing gate oxide rupture and false triggering in isolated gate drivers. | Use Scenario: Input-stage surge suppression on -48 V DC telecom rectifier outputs exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side distribution rail prior to POL converters. Use Value: Absorbs 3000 W pulses while maintaining <121 V clamping, ensuring downstream DC/DC controllers remain within absolute maximum ratings. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: CAN/LIN bus line protection in BCMs subjected to load dump and ISO 7637-2 pulse 5a/b. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed across differential bus lines near connector interface. Use Value: Withstands 30 kV ESD and clamps 8/20 μs surges to 157 V, preserving signal integrity and transceiver functionality. | Use Scenario: Protection of analog front-end inputs (e.g., 4–20 mA loops, RTD bridges) in PLC analog I/O modules. IC Role / Device Role / Timing Role: Low-leakage (≤1 μA @ 75 V) shunt clamp on sensor input traces. Use Value: Maintains <1 μA reverse leakage at rated VWM, avoiding measurement offset while delivering 121 V clamping during field-induced transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Same VWM (75 V) and bidirectional configuration, but lower PPPM (600 W) and higher VC (123 V @ 4.9 A) | Rated for lighter-duty surge environments (IEC 61000-4-5 Level 2); unsuitable for 3 kA 8/20 μs events | Select when cost-sensitive designs tolerate reduced surge margin and smaller SMB package saves board space |
| SMCJ75CA | Identical SMC package, same VWM and PPPM (3000 W), but slightly higher VC (123 V @ 24.4 A) and wider VBR tolerance (78.8–86.7 V) | Functionally interchangeable in most 3000 W surge applications; minor clamping variance does not affect system-level compliance | Preferred when sourcing flexibility is needed - shares same footprint, thermal performance, and qualification profile as 3.0C75CA-M3/I |
Compared with SMBJ75CA and SMCJ75CA, the 3.0C75CA-M3/I delivers tighter VBR (83.3–92.1 V), lower clamping voltage (121 V), and identical 3000 W rating in the industry-standard SMC outline - making it optimal for high-reliability industrial surge protection where clamping precision and energy handling are jointly critical.
