Overview
The CPC3982TTR is an N-channel, depletion-mode field-effect transistor (FET) manufactured by Littelfuse using IXYS Integrated Circuits' proprietary third-generation vertical DMOS process. This component operates with a drain-source voltage rating of 800V and offers a typical on-resistance of 380 ohms. It is housed in a surface-mount SOT-23 package and is supplied in tape-and-reel format for automated assembly.
Feature Summary
- Utilizes a third-generation vertical DMOS process for high-voltage performance
- Operates as an N-channel depletion-mode device
- Designed for economical silicon gate integration
Applications
- High-voltage switching circuits
- Power control systems requiring depletion-mode operation
- Industrial power management applications
Procurement Notes
Verify the specific suffix 'TTR' confirms the tape-and-reel packaging configuration when ordering. Ensure compatibility with SOT-23 footprint requirements during PCB layout. Confirm that the 800V rating meets the system's peak voltage demands. Validate that the depletion-mode characteristic aligns with the circuit's default state requirements before finalizing procurement.
Selection Notes
Select this component when a normally-on behavior is required in high-voltage environments. The SOT-23 package suits space-constrained designs. Consider the 380-ohm on-resistance impact on power dissipation. Verify thermal management capabilities within the 400mW limit if applicable to the specific operating conditions.
Part Context
This part belongs to the CPC3982 series of N-channel depletion-mode MOSFETs. The series leverages IXYS Integrated Circuits technology to provide robust high-voltage solutions. The TTR suffix specifically denotes the reel packaging variant, distinguishing it from bulk or tube options.
Replacement Considerations
Consult official Littelfuse documentation for verified cross-reference part numbers. Ensure any substitute maintains the N-channel depletion-mode characteristic and 800V rating. Verify pinout compatibility with the SOT-23 package before implementation.
