Product details
Overview
3.0C40CA-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), 40 V stand-off voltage (VWM), and 64.5 V maximum clamping voltage (VC) at 46.5 A IPPM. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
For engineers reviewing the 3.0C40CA-M3/I datasheet, 3.0C40CA-M3/I pinout, 3.0C40CA-M3/I application, or 3.0C40CA-M3/I equivalent, key selection criteria include bidirectional clamping capability, 175 °C junction temperature rating, MSL Level 1 moisture sensitivity, and compliance with IEC 61000-4-2 ESD (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 silicon avalanche structure delivers low incremental surge resistance and stable breakdown between 44.4 V and 49.1 V at 1 mA test current.
It meets JEDEC J-STD-020 MSL Level 1 with 260 °C reflow peak, features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. The device is halogen-free, RoHS-compliant, and rated for -55 °C to +175 °C operating junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.

|---|---|---|---|
| SMBJ40CA | Lower PPPM (600 W), same VWM (40 V), SMB package (smaller footprint, higher thermal resistance) | Suitable for lower-energy transients; not recommended for 3000 W surge environments | Select 3.0C40CA-M3/I when 3000 W peak pulse power and SMC thermal performance are required. |
| SMCJ40CA | Identical SMC package and 3000 W rating, but VBR min/max = 44.4 V / 49.1 V matches exactly; same clamping performance | Drop-in replacement with identical electrical and mechanical specs; differs only in branding and traceability | 3.0C40CA-M3/I and SMCJ40CA are functionally interchangeable in new designs and second-source procurement. |

FAQ
What is the maximum clamping voltage of the 3.0C40CA-M3/I under a 10/1000 μs surge?
The 3.0C40CA-M3/I has a maximum clamping voltage (VC) of 64.5 V at 46.5 A peak pulse current (IPPM) for a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components experience no more than 64.5 V during standardized surge events. The clamping performance is guaranteed across the full operating temperature range.
Does the 3.0C40CA-M3/I meet industry-standard ESD immunity requirements?
Yes, the 3.0C40CA-M3/I is rated for 30 kV ESD immunity per IEC 61000-4-2 in both contact and air discharge modes. This specification is verified per the manufacturer's test methodology and reflects its suitability for end-equipment subjected to handling and environmental electrostatic events without functional interruption or parametric shift.
What is the package type and mounting compatibility of the 3.0C40CA-M3/I?
The 3.0C40CA-M3/I uses the SMC (DO-214AB) surface-mount package with matte tin-plated leads. It complies with J-STD-002 solderability standards and JEDEC J-STD-020 MSL Level 1, enabling compatibility with standard reflow profiles peaking at 260 °C. Its footprint matches industry-standard SMC land patterns.
How does the 3.0C40CA-M3/I differ from unidirectional TVS diodes like 3.0C40A-M3/I?
The 3.0C40CA-M3/I is bidirectional, meaning it clamps voltage transients of either polarity symmetrically-ideal for AC lines or differential signals. In contrast, 3.0C40A-M3/I is unidirectional and only protects against positive-going surges relative to ground. Their VWM, VBR, and clamping values differ accordingly, making them non-interchangeable without circuit review.
Is the 3.0C40CA-M3/I suitable for automotive under-hood applications?
Yes, the 3.0C40CA-M3/I supports junction temperatures up to +175 °C and is qualified per AEC-Q200 stress test requirements when used within its specified derating curves. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating make it appropriate for engine control units, body controllers, and other high-temperature automotive subsystems.
