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 protection with 3000 W peak pulse power (10/1000 μs), 87.1 V maximum clamping voltage at 34.4 A, and 60.0–66.3 V breakdown voltage range. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
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 (VC = 87.1 V @ IPPM), standoff voltage (VWM = 54 V), bidirectional polarity, SMC package thermal performance (RthJA = 90 °C/W), and IEC 61000-4-2 ESD immunity (30 kV contact/air).
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 bidirectional architecture enables symmetrical clamping across both polarities without external biasing, and its low incremental surge resistance ensures minimal voltage overshoot during high-current events.
It meets J-STD-020 MSL Level 1 moisture sensitivity, supports reflow up to 260 °C peak, and delivers 30 kV ESD immunity per IEC 61000-4-2 - critical for robustness in unshielded industrial and telecom front-end circuits where transient energy exceeds 3000 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 60.0 V / 66.3 V - defines reliable conduction onset under surge conditions; ensures device remains off below 54 V operating voltage |
| VWM | 54 V - maximum continuous reverse working voltage; sets upper limit for safe DC/AC signal line operation |
| VC @ IPPM | 87.1 V @ 34.4 A (10/1000 μs) - clamping voltage during worst-case surge; determines protected circuit's maximum stress level |
| PPPM | 3000 W - peak pulse power handling capacity; validates suitability for IEC 61000-4-5 Level 4 surge testing |
| IPPM | 34.4 A - peak pulse current capability at rated clamping voltage; directly constrains PCB trace sizing and layout |
| TJ max. | +175 °C - maximum junction temperature; enables operation in high-ambient environments like enclosed power converters |
| ESD Rating | 30 kV (IEC 61000-4-2, contact/air) - qualifies for direct interface protection in handheld and field-deployable equipment |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, MSL Level 1, 260 °C reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Surge current return path | Bidirectional design means no functional cathode/anode distinction; terminals are symmetric for AC transients |
| Anode (unmarked end) | Surge current entry point | Terminal symmetry eliminates polarity dependency; simplifies layout on differential or AC-coupled lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, RS-485 buses, or transformer-coupled interfaces without polarity concerns |
| 3000 W (10/1000 μs) rating | Supports compliance with IEC 61000-4-5 surge immunity requirements for industrial equipment up to Level 4 |
| 87.1 V clamping at 34.4 A | Limits downstream voltage stress to safe levels for 60 V-rated MOSFETs and logic ICs in power supply rails |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for additional ESD protection stages on exposed ports such as USB, Ethernet, or sensor connectors |
| SMC package thermal resistance | RthJA = 90 °C/W enables sustained surge handling without derating in standard FR4 layouts with 2 oz copper |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|

IC Role / Device Role / Timing Role: Bidirectional TVS placed between LIN data line and ground to suppress ±100 V, 50 ms pulses. Use Value: Ensures communication continuity by clamping transients within 100 ns while surviving repeated 30 kV ESD events per ISO 10605. | Use Scenario: Shielding analog outputs (e.g., 4–20 mA loops) and digital sensor interfaces (I²C, SPI) from EFT and surge coupling in factory-floor PLC modules. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF at 0 V) shunt protector placed at connector entry point before signal conditioning circuitry. Use Value: Preserves signal integrity with <1 nA leakage at 54 V while delivering 30 kV ESD robustness per IEC 61000-4-2. |
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 peak pulse power (600 W), same VWM (54 V), SMB package (smaller footprint, higher RthJA) | Suitable only for lower-energy transients (e.g., IEC 61000-4-4 EFT), not Level 4 surge | Select when board space is constrained and surge threat level is limited to EFT or low-energy switching noise |
| SMCJ54A | Unidirectional, identical VWM/VC, same SMC package, but requires correct polarity placement | Applicable only on DC-biased lines (e.g., +5 V logic rails); unsuitable for AC or differential buses | Choose for cost-sensitive DC power rail protection where polarity is fixed and bidirectionality is unnecessary |
Compared with SMBJ54CA and SMCJ54A, the 3.0C54CA-M3 uniquely combines 3000 W surge capability, bidirectional operation, and SMC thermal performance - making it the only option among the three qualified for full IEC 61000-4-5 Level 4 compliance in space-constrained industrial designs.

FAQ
What is the breakdown voltage range for the 3.0C54CA-M3?
The 3.0C54CA-M3 has a specified breakdown voltage (VBR) range of 60.0 V minimum to 66.3 V maximum at 1.0 mA test current. This range ensures consistent turn-on behavior across production lots while maintaining margin above its 54 V standoff voltage (VWM). The 3.0C54CA-M3 is tested per ANSI/IEEE C62.35 standards and guarantees this VBR window under all qualified operating conditions.
Does the 3.0C54CA-M3 require polarity-aware PCB layout?
No - the 3.0C54CA-M3 is a bidirectional TVS diode with symmetric terminal construction and no polarity marking. Its electrical behavior is identical in both directions, enabling placement across AC-coupled lines, differential buses (e.g., RS-485), or transformer-isolated interfaces without orientation constraints. This eliminates assembly errors and simplifies layout for the 3.0C54CA-M3 in mixed-signal systems.
What is the maximum clamping voltage of the 3.0C54CA-M3 under surge conditions?
The 3.0C54CA-M3 clamps to a maximum of 87.1 V when subjected to its rated peak pulse current of 34.4 A using the standard 10/1000 μs waveform. This value is guaranteed across temperature and lot variations per Vishay Document Number 98266. Designers use this 87.1 V clamping voltage to verify that downstream components like 100 V MOSFETs or 75 V op-amps remain within safe operating limits during surge events.
Is the 3.0C54CA-M3 compliant with lead-free soldering standards?
Yes - the 3.0C54CA-M3 carries the "-M3" suffix, indicating halogen-free, RoHS-compliant construction with matte tin-plated leads qualified for soldering per J-STD-002 and JESD 22-B102. It supports lead-free reflow profiles with a maximum peak temperature of 260 °C (MSL Level 1), and passes JESD 201 Class 2 whisker testing. These qualifications are fully documented for the 3.0C54CA-M3 in Vishay's official specifications.
Can the 3.0C54CA-M3 be used for IEC 61000-4-5 Level 4 surge protection?
Yes - the 3.0C54CA-M3 is rated for 3000 W peak pulse power (10/1000 μs), which satisfies the 4 kV/2 Ω open-circuit voltage requirement of IEC 61000-4-5 Level 4 when properly implemented with appropriate PCB layout and coordination. Its 87.1 V clamping voltage and 34.4 A peak current capability have been validated for this standard, making the 3.0C54CA-M3 a proven solution for industrial equipment requiring full Level 4 immunity.
