Product details
Overview
3.0C54CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge clamping with 3000 W peak pulse power (10/1000 μs), 87.1 V maximum clamping voltage at 34.4 A, and 54 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces against lightning-induced transients.
For engineers reviewing the 3.0C54CA-M3 datasheet, 3.0C54CA-M3 pinout, 3.0C54CA-M3 application, or 3.0C54CA-M3 equivalent, key selection criteria include clamping voltage at rated IPPM, bidirectional polarity, SMC package thermal performance (RthJA = 90 °C/W), and compliance with IEC 61000-4-2 ESD (30 kV contact/air).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering when reverse transient voltage exceeds its 60.0–66.3 V breakdown range (at 1 mA). Its low incremental surge resistance ensures stable clamping under fast-rising 8/20 μs surges up to 265 A, while maintaining bidirectional symmetry for AC-coupled or floating signal line protection.
Designed for operation from –55 °C to +175 °C junction temperature, it leverages SMC package construction with matte tin-plated leads (J-STD-002 compliant), UL 94 V-0 molding compound, and MSL Level 1 moisture sensitivity-enabling reflow compatibility at 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin for protected circuitry. |
| VBR min/max | 60.0 V / 66.3 V - Breakdown occurs within this range at 1 mA test current; sets threshold for transient conduction onset. |
| VC @ IPPM | 87.1 V at 34.4 A (10/1000 μs) - Clamping voltage during standardized surge; determines worst-case overvoltage seen by downstream components. |
| PPPM | 3000 W - Peak pulse power handling capability with 10/1000 μs waveform; quantifies single-event surge energy absorption. |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact & air) - Confirmed immunity level for electrostatic discharge events in end-user environments. |
| TJ max | +175 °C - Maximum allowable junction temperature; enables reliable operation in high-ambient industrial or automotive under-hood locations. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional device with no polarity marking; case meets UL 94 V-0, terminals are matte tin-plated for J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| 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 functional distinction in layout. |
| Anode (unmarked end) | Anode/Cathode terminal pair | Identical electrical role to marked end; symmetric clamping behavior eliminates orientation dependency during PCB placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled, differential, or floating signal paths without polarity constraints or external circuit modification. |
| 3000 W peak pulse power (10/1000 μs) | Supports robust defense against IEC 61000-4-5 Level 4 surges (4 kV line-earth) in industrial power input stages. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on protected ICs-e.g., 87.1 V clamp limits exposure for 60 V-rated interface ICs. |
| MSL Level 1, 260 °C peak reflow | Permits standard lead-free SMT assembly without pre-baking or special handling, reducing manufacturing overhead. |
Applications
| Industrial Motor Drive I/O Protection | Telecom Line Interface Surge Suppression |
|---|---|
Use Scenario: Protecting digital I/O lines connected to PLC modules exposed to inductive kickback from relay coils and solenoid drivers. IC Role / Device Role / Timing Role: Shunt TVS device that diverts >30 A transients away from microcontroller GPIOs and level translators. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V logic interfaces by clamping to ≤87.1 V during 10/1000 μs surges. | Use Scenario: Safeguarding RS-485 transceivers and Ethernet PHYs on telecom base station backplanes subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end surge limiter placed before common-mode chokes and isolation transformers. Use Value: Maintains signal integrity by limiting transient overshoot to <90 V, preserving receiver input stage reliability across 10⁵+ surge events. |
| Automotive Body Control Module Sensor Inputs | Consumer Appliance Power Supply Input Stage |
Use Scenario: Shielding LIN bus sensors (e.g., door lock actuators) from load dump and jump-start transients in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional clamping element co-located with connector entry points to intercept fast-rising transients before filtering networks. Use Value: Withstands 30 kV ESD per IEC 61000-4-2 and clamps 8/20 μs surges up to 265 A-meeting ISO 16750-2 Pulse 5a requirements. | Use Scenario: Protecting AC-DC converter primary-side control ICs and optocouplers from mains-borne surges in smart home appliances. IC Role / Device Role / Timing Role: Secondary-level TVS placed across bridge rectifier outputs or bulk capacitor inputs to absorb residual transients escaping MOV-based primary protection. Use Value: Adds fail-safe redundancy with 3000 W rating and 175 °C TJ max, enabling sustained operation in enclosed, thermally constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54CA | Lower PPPM (600 W), same VWM (54 V), SMB package (smaller footprint, higher RthJA ≈ 110 °C/W) | Suitable only for lower-energy transients (e.g., ESD-only); not rated for IEC 61000-4-5 line surges | Select when board space is critical and surge threat level is limited to HBM/CDM ESD. |
| SMCJ54A | Unidirectional variant, identical VWM/VC/PPPM specs, same SMC package and thermal metrics | Requires correct polarity placement; unsuitable for AC or floating signals without additional design review | Choose only for DC-biased rails where polarity is fixed and unidirectional clamping suffices. |
Compared with SMBJ54CA and SMCJ54A, the 3.0C54CA-M3 delivers 5× higher surge power handling than SMBJ54CA in the same mounting area as SMCJ54A while retaining bidirectional flexibility-making it optimal for space-constrained, high-threat industrial and telecom designs requiring universal polarity coverage.

FAQ
What is the breakdown voltage range of the 3.0C54CA-M3?
The 3.0C54CA-M3 has a specified breakdown voltage (VBR) range of 60.0 V to 66.3 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent turn-on behavior across production lots and defines the minimum voltage at which the device initiates clamping during transient events.
Does the 3.0C54CA-M3 require polarity-aware PCB layout?
No-the 3.0C54CA-M3 is a bidirectional TVS diode with symmetrical electrical characteristics; either terminal may serve as anode or cathode depending on transient polarity. Its SMC package carries no polarity marking, and PCB layout does not require orientation verification during placement.
What is the maximum clamping voltage of the 3.0C54CA-M3 under a 10/1000 μs surge?
The 3.0C54CA-M3 exhibits a maximum clamping voltage (VC) of 87.1 V when subjected to its rated peak pulse current of 34.4 A using the standardized 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and represents the worst-case overvoltage imposed on protected circuitry during such an event.
Is the 3.0C54CA-M3 compliant with lead-free reflow standards?
Yes-the 3.0C54CA-M3 is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering processes. Its matte tin-plated terminals meet J-STD-002 solderability requirements and JESD 201 Class 2 whisker resistance.
How does the 3.0C54CA-M3 perform under repeated surge stress?
The 3.0C54CA-M3 is characterized for non-repetitive surge events per datasheet conditions; its 3000 W rating applies to single-pulse testing. For repetitive surge applications, derating per Figure 2 of the Vishay document 98266 is required-junction temperature rise must remain within the –55 °C to +175 °C operational limit to ensure long-term reliability.
