Product details
Overview
3.0C15CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 15 V standoff voltage (VWM), 16.7–18.5 V breakdown (VBR), 24.4 V clamping voltage at 923 A peak pulse current (10/1000 μs), and 3000 W peak pulse power rating.
For engineers reviewing the 3.0C15CA-M3 datasheet, 3.0C15CA-M3 pinout, 3.0C15CA-M3 application, or 3.0C15CA-M3 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, bidirectional ESD robustness up to 30 kV (IEC 61000-4-2), thermal resistance (RthJA = 90 °C/W), and compatibility with industrial-grade reflow profiles (MSL level 1, 260 °C peak).
Technical Context
This TVS diode operates as a voltage-clamping protection device across bidirectional signal or DC power rails. Its silicon avalanche structure enables sub-nanosecond response time and low incremental surge resistance, ensuring fast suppression of inductive switching spikes and lightning-induced transients without affecting normal circuit operation.
It is rated for continuous operation from –55 °C to +175 °C junction temperature and meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements. The matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR min/max | 16.7 V / 18.5 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 24.4 V at 923 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 3000 W - Peak pulse power handling capability; supports high-energy transient suppression per IEC 61000-4-5. |
| ESD Rating | ±30 kV (HBM, contact & air) - Robust electrostatic discharge immunity per IEC 61000-4-2. |
| TJ max | +175 °C - Maximum junction temperature; enables use in high-ambient industrial and automotive under-hood environments. |
| RthJA | 90 °C/W - Thermal resistance junction-to-ambient on FR4 PCB; informs heatsinking and layout requirements. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL level 1 (260 °C peak reflow). Bidirectional device - no polarity marking; cathode/anode terminals are symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink during positive surge | Terminal where avalanche conduction initiates when voltage exceeds VBR in either polarity; symmetric behavior enables bidirectional clamping. |
| Anode | Transient current sink during negative surge | Same physical terminal as cathode in bidirectional configuration; no functional distinction - device conducts identically in both directions. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 3000 W peak pulse power (10/1000 μs) | Supports high-energy surge events common in industrial motor drives and telecom line interfaces. |
| 24.4 V clamping at 923 A | Limits downstream voltage stress to logic-level ICs (e.g., microcontrollers, RS-485 transceivers) during transients. |
| 30 kV HBM ESD immunity | Exceeds IEC 61000-4-2 Level 4, eliminating need for additional ESD protection on exposed ports. |
| MSL level 1, 260 °C peak | Compatible with standard lead-free reflow processes without preconditioning or special handling. |
Applications
| Industrial Motor Drive Control | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Lower PPPM (600 W), same VWM (15 V), SMB package (smaller footprint, higher RthJA ≈ 110 °C/W) | Suitable only for lower-energy transients; not recommended for IEC 61000-4-5 line surges | Select 3.0C15CA-M3 when 3000 W surge handling or industrial-grade thermal performance is required. |
| SMCJ15CA | Identical SMC package and 3000 W rating, but VBR min/max = 16.7–18.5 V (same), VC = 24.4 V (same); differs only in JEDEC traceability and M3 suffix compliance | No functional difference; identical electrical and mechanical specs per Vishay documentation | 3.0C15CA-M3 and SMCJ15CA are functionally interchangeable; 3.0C15CA-M3 adds halogen-free and JESD201 Class 2 whisker assurance. |
Compared with SMBJ15CA, the 3.0C15CA-M3 delivers 5× higher surge power handling and superior thermal dissipation; versus SMCJ15CA, it offers identical protection performance with enhanced process controls for high-reliability industrial deployment.

FAQ
What is the clamping voltage of the 3.0C15CA-M3 under a 10/1000 μs surge?
The 3.0C15CA-M3 clamps to 24.4 V at its rated peak pulse current of 923 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the maximum voltage seen by downstream components during such an event. It is specified in the Electrical Characteristics table on page 2 of Vishay document 98266.
Is the 3.0C15CA-M3 unidirectional or bidirectional?
The 3.0C15CA-M3 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative voltage transients. Its marking code "BEM3" and absence of polarity marking confirm this configuration, and its VBR and VC specifications are identical in both directions per the datasheet.
What is the maximum operating temperature for the 3.0C15CA-M3?
The 3.0C15CA-M3 has a maximum junction temperature (TJ max) of +175 °C and an operating junction/storage temperature range of –55 °C to +175 °C. This rating allows reliable deployment in under-hood automotive, industrial drive cabinets, and outdoor telecom enclosures without derating at ambient temperatures up to +125 °C.
Does the 3.0C15CA-M3 meet RoHS and halogen-free requirements?
Yes, the 3.0C15CA-M3 carries the "-M3" suffix, indicating it is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 for tin whisker resistance. The molding compound meets UL 94 V-0 flammability, and terminals are matte tin plated per J-STD-002 and JESD22-B102.
What is the ESD withstand capability of the 3.0C15CA-M3?
The 3.0C15CA-M3 is rated for ±30 kV ESD immunity per IEC 61000-4-2 in both contact and air discharge modes. This performance is confirmed in the Immunity to Static Electrical Discharge section (page 3) of Vishay document 98266 and eliminates the need for supplemental ESD protection on protected lines.
