Product details
Overview
3.0C90CA-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), 146 V clamping voltage at 20.5 A IPPM, and 90 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C90CA-M3/H datasheet, 3.0C90CA-M3/H pinout, 3.0C90CA-M3/H application, or 3.0C90CA-M3/H equivalent, key selection criteria include clamping performance under 10/1000 μs transients, bidirectional polarity, MSL Level 1 reflow compatibility, and 175 °C junction temperature rating.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transient overvoltages induced by inductive switching or lightning surges. Its bidirectional architecture enables symmetrical clamping across both polarities without external polarity management.
It meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air), supports JEDEC-compliant thermal derating, and features low incremental surge resistance - critical for minimizing voltage overshoot during fast-rising transients in DC power distribution networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR min/max | 100 V / 111 V - breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 146 V at 20.5 A - clamping voltage during 10/1000 μs surge; limits downstream voltage stress to ≤146 V. |
| PPPM | 3000 W - peak pulse power handling capability per 10/1000 μs waveform; supports high-energy transient suppression. |
| TJ max | +175 °C - maximum junction temperature; enables reliable operation in high-ambient industrial environments. |
| ESD Rating | 30 kV HBM (contact/air) - exceeds IEC 61000-4-2 Level 4, suitable for unshielded board-level ESD protection. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow), matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Surge return path | Bidirectional device - no functional cathode/anode; marking denotes orientation for automated placement only. |
| Anode (unmarked end) | Surge return path | Electrically symmetric terminals; either end connects to protected line or ground depending on layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 3000 W peak pulse power | Supports robust protection against severe 10/1000 μs surges common in industrial motor drives and telecom power supplies. |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage exposure to downstream ICs while maintaining margin above 90 V operating rail. |
| MSL Level 1 rating | Allows standard SMT reflow without moisture sensitivity concerns - eliminates bake-out requirement for production. |
Applications
| Industrial Motor Drive Protection | Telecom DC Power Input |
|---|---|
Use Scenario: Suppresses switching transients from IGBT gate drivers and relay coils in PLC output modules. IC Role / Device Role / Timing Role: Shunt TVS placed across DC bus or gate drive supply to clamp spikes before they reach logic-level controllers. Use Value: Limits transient voltage to ≤146 V, preventing latch-up or gate oxide damage in 3.3 V/5 V microcontrollers and isolated gate drivers. | Use Scenario: Protects primary-side DC-DC converter inputs in base station power supplies exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of input filter and controller ICs. Use Value: Absorbs 3000 W surges without degradation, maintaining system uptime in outdoor telecom infrastructure. |
| Sensor Signal Line Protection | Automotive Body Control Module |
Use Scenario: Shields analog outputs of pressure/temperature sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector interface to prevent ESD damage to ADC front-end. Use Value: Clamps 30 kV HBM discharges while adding <100 pF capacitance - preserves signal integrity for 10 kHz sensor bandwidth. | Use Scenario: Safeguards LIN bus transceivers and microcontroller I/O pins against load dump and jump-start transients. IC Role / Device Role / Timing Role: Bidirectional TVS on 12 V supply rail and data lines to meet ISO 7637-2 Pulse 5a requirements. Use Value: Withstands 175 °C junction temperature and maintains clamping performance after repeated 20.5 A surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA | Lower PPPM (600 W), same VWM (90 V), SMB package (smaller footprint, higher RthJA) | Suitable for lower-energy surges; not recommended for 3000 W IEC 61000-4-5 compliance | Select 3.0C90CA-M3/H when full 3000 W surge immunity is required in space-constrained SMC layouts. |
| SMCJ90CA | Identical electrical specs and SMC package; differs only in marking code and tape/reel packaging (no /H suffix) | No functional difference; /H denotes 7" reel (850 pcs), whereas SMCJ90CA may ship in alternate reels | 3.0C90CA-M3/H and SMCJ90CA are electrically interchangeable; choose based on logistics and inventory alignment. |

FAQ
What is the clamping voltage of the 3.0C90CA-M3/H under a 10/1000 μs surge?
The 3.0C90CA-M3/H has a maximum clamping voltage (VC) of 146 V at 20.5 A peak pulse current (IPPM) for a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream circuitry remains below critical overvoltage thresholds during surge events.
Is the 3.0C90CA-M3/H suitable for automotive applications?
Yes, the 3.0C90CA-M3/H is rated for TJ up to +175 °C and meets IEC 61000-4-2 ESD immunity (30 kV), making it suitable for under-hood and body control module applications. However, it is not AEC-Q200 qualified - design-in requires validation per ISO 7637-2 for load dump and pulse testing.
Does the 3.0C90CA-M3/H have polarity markings?
No - the 3.0C90CA-M3/H is a bidirectional TVS diode with no functional polarity. The device uses a single band marking (GGX3) for traceability and placement orientation only; both terminals are electrically identical and interchangeable in circuit layout.
What is the thermal resistance of the 3.0C90CA-M3/H?
The 3.0C90CA-M3/H has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A, and junction-to-mount (RthJM) of 4.0 °C/W per JEDEC 51-14, enabling effective heat dissipation during repetitive surge events.
Can the 3.0C90CA-M3/H replace older SMCJ90CA parts?
Yes - the 3.0C90CA-M3/H is functionally and physically identical to SMCJ90CA in electrical specs, SMC package, and mounting dimensions. Differences are limited to part numbering convention and M3-grade reliability screening; no PCB or schematic changes are needed for drop-in replacement.
