Overview
The CPC3710C is a surface-mount N-channel depletion-mode MOSFET manufactured by IXYS Integrated Circuits Division. It features a drain-source voltage rating of 250 V and operates within a junction temperature range of -55°C to 125°C. The device utilizes an SOT-89 (TO-243AA) package with a maximum power dissipation of 1.4 W at ambient temperature. Key electrical characteristics include a gate-source voltage limit of ±15 V, an input capacitance of 350 pF at 25 V, and a maximum on-resistance of 10 ohms at 220 mA and 0 V gate drive.
Feature Summary
- Depletion-mode operation allowing conduction at zero gate-source voltage
- High-voltage capability suitable for demanding switching applications
- Surface-mount construction in a compact SOT-89 package
Applications
- High-voltage analog switching circuits
- Load switching in industrial control systems
- Signal routing in test and measurement equipment
Procurement Notes
Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm exact electrical tolerances and marking codes. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, as availability varies by distributor. Confirm RoHS compliance status and lead times directly with authorized suppliers before finalizing procurement plans.
Selection Notes
Select this component when a normally-on behavior is required for high-voltage signal paths. The 250 V rating provides sufficient headroom for many industrial applications. Consider the 10 ohm on-resistance at low currents when designing bias networks. The SOT-89 package offers a balance between thermal performance and board space efficiency for single-channel designs.
Part Context
This component belongs to the CPC37xx series of high-voltage depletion-mode MOSFETs from IXYS. These devices are engineered for applications requiring reliable switching of high voltages with minimal gate drive complexity. The series leverages advanced silicon technology to deliver robust performance in compact surface-mount packages.
Replacement Considerations
Consult the official CPC3710 datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 250 V drain-source voltage and depletion-mode characteristic. Cross-reference package dimensions and thermal resistance values to ensure mechanical compatibility.
