Product details
Overview
3.0C30CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 30 V stand-off voltage (VWM), and 48.4 V maximum clamping voltage at 62.0 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C30CA-M3/I datasheet, 3.0C30CA-M3/I pinout, 3.0C30CA-M3/I application, or 3.0C30CA-M3/I equivalent, this device delivers verified ESD immunity (30 kV HBM), MSL Level 1 reliability, halogen-free RoHS-compliant construction, and precise clamping performance critical for robust overvoltage design in DC power inputs and data line interfaces.
Technical Context
This TVS diode operates bidirectionally to clamp both positive and negative transients without polarity marking. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and lightning-induced surges on sensitive nodes.
The device features a 175 °C maximum junction temperature, 90 °C/W junction-to-ambient thermal resistance, and meets IEC 61000-4-2 (30 kV contact/air) and IEC 61000-4-5 surge immunity standards - enabling use in harsh environments where thermal stability and repeatable clamping are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected circuitry. |
| VBR (min/max) | 33.3 V / 36.8 V - Breakdown voltage range at 1 mA test current; ensures reliable turn-on above normal operating voltage. |
| VC @ IPPM | 48.4 V at 62.0 A - Clamping voltage under 10/1000 μs surge; limits transient energy delivered to downstream components. |
| PPPM | 3000 W - Peak pulse power handling (10/1000 μs); supports high-energy surge events common in industrial motor drives. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in high-ambient environments like enclosed power supplies. |
| ESD Rating | 30 kV (HBM, contact & air) - Confirmed immunity level per IEC 61000-4-2; eliminates need for additional ESD stages in front-end protection. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Molding compound meets UL 94 V-0. Polarity not marked (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Anode/Cathode terminal pair | Bidirectional conduction path - either end serves as anode or cathode depending on transient polarity; no fixed polarity assignment. |
| Anode (unmarked end) | Anode/Cathode terminal pair | Same physical terminal as cathode under reverse transient; symmetric layout simplifies PCB routing and eliminates orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without external polarity management. |
| 3000 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil de-energization or nearby lightning strikes in industrial control cabinets. |
| 48.4 V clamping at 62 A | Keeps protected MOSFET gate-source voltage below absolute maximum rating during 100 V surge events on 24 V bus. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without moisture-related popcorning or delamination risks. |
| 30 kV HBM ESD immunity | Meets stringent electrostatic discharge requirements for field-deployed equipment without supplemental protection. |
Applications
| Industrial Motor Drive Inputs | Telecom Power Supply Rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Lower PPPM (600 W), same VWM (30 V), SMB package (smaller footprint, higher RthJA = 110 °C/W) | Limited to lower-energy surges; unsuitable for industrial motor drive inputs requiring 3000 W handling. | Select only when space-constrained and surge energy is confirmed ≤600 W. |
| SMCJ30CA | Same SMC package, identical VWM (30 V), but 1500 W PPPM and higher VC (53.3 V at 28.2 A) | Higher clamping voltage reduces margin for 36 V-rated downstream devices; insufficient for 3000 W compliance testing. | Use only if cost sensitivity outweighs clamping performance and surge rating requirements. |
Compared with 3.0C30CA-M3/I, SMBJ30CA offers smaller size but sacrifices 80 % peak power capability and thermal robustness, while SMCJ30CA retains the SMC form factor but fails to meet the 3000 W requirement and clamps 4.9 V higher - making 3.0C30CA-M3/I the only option satisfying full industrial surge immunity and low-clamp design goals.

FAQ
What is the breakdown voltage range of the 3.0C30CA-M3/I?
The 3.0C30CA-M3/I has a specified breakdown voltage (VBR) range of 33.3 V to 36.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This ensures consistent turn-on behavior above its 30 V stand-off voltage while accommodating process variation across production lots.
Does the 3.0C30CA-M3/I require polarity-aware PCB layout?
No - the 3.0C30CA-M3/I is a bidirectional TVS diode with no polarity marking on the SMC (DO-214AB) package. Either terminal functions as anode or cathode depending on transient polarity, allowing orientation-agnostic placement and simplified board routing.
What is the maximum clamping voltage of the 3.0C30CA-M3/I under a 10/1000 μs surge?
The 3.0C30CA-M3/I clamps to a maximum of 48.4 V at 62.0 A peak pulse current under the standardized 10/1000 μs waveform. This value is guaranteed per datasheet Table 1 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0C30CA-M3/I compliant with lead-free reflow processes?
Yes - the 3.0C30CA-M3/I is rated MSL Level 1 and qualified for lead-free reflow with a maximum peak temperature of 260 °C, per J-STD-020. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
How does the 3.0C30CA-M3/I perform under ESD stress?
The 3.0C30CA-M3/I is tested to IEC 61000-4-2 and delivers 30 kV ESD immunity in both contact and air discharge modes. This performance is intrinsic to its silicon structure and requires no external circuitry to meet Class 4 ESD protection requirements.
