Overview
The DN2540N3-G-P003 is an N-Channel Depletion Mode Vertical DMOS FET manufactured by Microchip Technology (originally Supertex). It features a TO-92 package with a drain-to-source breakdown voltage of 400V and a maximum on-resistance of 25 Ohms. The device supports a continuous drain current of 120mA and dissipates up to 1.0W of power. Operating temperatures range from -55°C to +150°C, with gate-to-source voltage limits of ±20V.
Feature Summary
- Utilizes advanced vertical DMOS structure for high input impedance and low input capacitance.
- Inherently free from thermal runaway and thermally-induced secondary breakdown due to positive temperature coefficient.
- Designed for fast switching speeds suitable for high-frequency applications.
Applications
- Normally-on switches
- Solid state relays
- Linear amplifiers
- Constant current sources
Procurement Notes
Verify the specific P003 packing configuration against project requirements before ordering. Confirm that the lead-free RoHS compliant status meets environmental standards. Ensure the TO-92 through-hole mounting style aligns with the PCB layout. Check for any obsolete status or lifecycle changes directly with the manufacturer.
Selection Notes
Select this component for circuits requiring normally-on behavior without external biasing. The 400V rating suits high-voltage isolation tasks. Consider the 25 Ohm on-resistance for low-current load handling. Verify thermal management capabilities within the TO-92 package constraints for continuous operation.
Part Context
This part belongs to the DN2540 series of depletion mode MOSFETs originally developed by Supertex Inc. and now produced by Microchip Technology. The series includes variants in different packages such as TO-220 and SOT-89, offering flexibility for various power and thermal requirements while maintaining consistent electrical characteristics.
Replacement Considerations
Direct substitutes include DN2540N3-G and DN2540N3-G-P002. Cross-reference pinouts and thermal resistance values when replacing with other depletion mode MOSFETs to ensure compatibility with existing circuit designs.
