Microchip N-Channel Depletion Mode MOSFET, 500 mA, 400 V, TO-220, 3-Pin, Through Hole DN2540N5-G

Microchip DN2540N5-G is an N-Channel depletion mode MOSFET designed for industrial electronic applications requiring a high voltage rating of 400 V and continuous drain current of 500 mA. Packaged in a 3-pin TO-220 through-hole form factor, this transistor ensures robust mechanical and electrical connections.

The DN2540 series offers low input capacitance and fast switching speeds, making these devices ideal for normally-on switch applications, solid state relay circuits, linear amplifiers, power supply circuits, constant current sources, converters, and telecom equipment. The depletion mode characteristic provides normally-on operation, simplifying design architectures requiring default conduction.

Its operating temperature range spans from -55°C to 150°C, suitable for demanding environments. The maximum power dissipation of 15 watts accommodates moderate power applications. The device's maximum drain-source resistance of 25 ohms ensures minimal conduction loss, while the gate-source voltage rating of -20 V to +20 V provides a wide control window.

Features including high input impedance and freedom from secondary breakdown enhance reliability in industrial, telecom, and laboratory settings. The TO-220 package's dimensions (approx. 16.51 mm height, 10.7 mm length, 4.83 mm width) facilitate easy mounting and heat dissipation, with through-hole pins suitable for PCB insertion.

Designed for normally-on switches and solid state relays. Supports converter and telecom circuit requirements. Built for linear amplifiers and constant current sources. High input impedance reduces load on driving circuitry.

Fast switching speeds enable efficient power management. Low input capacitance minimizes switching losses. Robust power dissipation capacity of 15W. Wide operating temperature range from -55°C to 150°C.

Microchip's DN2540N5-G MOSFET is a reliable discrete semiconductor component suited for advanced industrial, electronic, and power management applications. Its feature set guarantees performance stability and ease of integration across multiple domains including manufacturing machinery, telecommunications infrastructure, and laboratory automation.
