Product details
Overview
3.0C28CA-M3/H 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), 31.1–34.4 V breakdown voltage, and 45.4 V clamping voltage at 66.1 A. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and telecom systems.
For engineers reviewing the 3.0C28CA-M3/H datasheet, 3.0C28CA-M3/H pinout, 3.0C28CA-M3/H application, or 3.0C28CA-M3/H equivalent, this page delivers verified electrical parameters, SMC package mechanical data, bidirectional clamping behavior, ESD immunity (30 kV HBM), and real-world use cases in power supply input stages and interface line protection.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown range (31.1–34.4 V), it avalanches to limit transient energy by diverting current away from downstream circuitry. Its low incremental surge resistance and fast response time ensure minimal overshoot during 8/20 μs and 10/1000 μs transients.
Rated for -55 °C to +175 °C junction temperature, 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. The -M3 suffix confirms halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.1 V / 34.4 V - defines precise avalanche initiation window for reliable triggering without false trips |
| VWM | 28 V - maximum continuous reverse operating voltage before leakage rises above 1.0 μA |
| VC @ IPPM | 45.4 V @ 66.1 A - clamping voltage under 10/1000 μs surge, limiting downstream stress to safe levels |
| PPPM | 3000 W - peak pulse power handling capacity determines survivability against standard lightning surges |
| ESD Rating | 30 kV (HBM, contact & air) - ensures robustness against human-body static discharge in assembly and field environments |
| TJ max | +175 °C - enables operation in high-temperature industrial enclosures and near power components |
| RthJA | 90 °C/W - thermal resistance to ambient on FR4 PCB informs derating requirements for sustained surge duty cycles |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional device with no polarity marking; molded compound rated UL 94 V-0; terminals are matte tin-plated for reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Anode/Cathode terminal pair | Bidirectional structure means either terminal serves as anode or cathode depending on transient polarity - no fixed polarity required in layout |
| Anode (unmarked end) | Anode/Cathode terminal pair | Same physical terminal as cathode under reverse polarity; symmetric conduction enables single-device protection of AC or differential lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects both positive and negative transients on same signal or power rail without external polarity management |
| 3000 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) in properly designed interfaces |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors, preserving margin for logic-level tolerance |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead for high-volume SMT lines |
| Halogen-free & RoHS-compliant (-M3) | Meets global environmental compliance mandates and supports lead-free assembly without compromising reliability |
Applications
| Industrial Motor Drive Input Protection | Telecom Ethernet Port Surge Protection |
|---|---|
Use Scenario: Protecting DC bus inputs of variable-frequency drives from inductive kickback during contactor switching and regenerative braking events. IC Role / Device Role / Timing Role: Shunt-type transient voltage suppressor placed across input terminals to clamp spikes before they reach rectifier and bulk capacitor stages. Use Value: Limits transient voltage to ≤45.4 V, preventing overvoltage failure of 60 V-rated electrolytic capacitors and bridge rectifiers under 66.1 A surge conditions. | Use Scenario: Safeguarding 10/100/1000BASE-T PHY interfaces against lightning-induced surges coupled onto unshielded twisted-pair cabling. IC Role / Device Role / Timing Role: Bidirectional TVS mounted on each differential pair (e.g., TX+/TX−, RX+/RX−) to clamp common-mode and differential-mode transients. Use Value: Maintains signal integrity by clamping within 45.4 V while preserving <10 pF junction capacitance at 0 V bias, avoiding bandwidth degradation in 100 MHz+ Ethernet links. |
| Automotive Body Control Module Power Rail | Consumer Appliance Sensor Interface Protection |
Use Scenario: Securing 12 V power inputs of BCMs against load-dump and jump-start transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Primary front-end TVS on main power entry, coordinated with upstream fuses and downstream LDOs to absorb >3000 W pulses. Use Value: Survives 12 V system load-dump pulses (ISO 7637-2 Pulse 5a) with clamping below 48 V, protecting 36 V-rated microcontrollers and CAN transceivers. | Use Scenario: Shielding analog output lines of temperature/humidity sensors in smart HVAC units from ESD and relay-switching noise. IC Role / Device Role / Timing Role: Low-leakage (≤1.0 μA at 28 V) TVS placed directly at connector pins to prevent latch-up or gate oxide damage in precision ADC front-ends. Use Value: Delivers 30 kV HBM ESD immunity without adding measurable leakage or capacitance that would degrade 16-bit ADC accuracy or offset stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ28CA | Lower peak pulse power (600 W), smaller SMB package (DO-214AA), VBR = 31.1–34.4 V identical | Suitable only for lower-energy transients (IEC 61000-4-5 Level 2); limited thermal mass reduces surge repetition capability | Select when board space is constrained and surge threat level is moderate (e.g., consumer USB ports) |
| SMCJ28CA | Same SMC package and 3000 W rating, but VBR = 31.1–34.4 V and VC = 45.4 V match exactly; differs only in packaging suffix (-H vs. standard reel) | Functionally identical performance and footprint; differs only in tape-and-reel delivery format (850 vs. 3500 units per reel) | Choose for direct drop-in replacement where procurement logistics favor alternate reel size or vendor stock availability |
Compared with SMBJ28CA, 3.0C28CA-M3/H provides five times higher surge energy handling and superior thermal dissipation in the larger SMC body; versus SMCJ28CA, it offers identical protection specs but with -M3 halogen-free compliance and -H tape/reel configuration optimized for high-mix SMT lines.
