Microchip N-Channel MOSFET 130 mA 450 V Depletion Mode 3-Pin TO-92 DN3545N3-G

Microchip DN3545N3-G is a high-voltage N-Channel MOSFET transistor operating in depletion mode, designed for discrete semiconductor applications requiring low input leakage, fast switching speeds, and reliable performance. It offers a maximum continuous drain current of 130 mA and can withstand up to 450 V across its drain-source terminals. Packaged in a durable TO-92 encapsulation with 3 pins, it supports through-hole mounting, making it ideal for industrial, laboratory, and commercial electronics assembly.

This MOSFET features a low on-resistance and high input impedance, which ensures efficient power management and reduced signal losses. Its channel mode is depletion type, which means it acts as a normally-on switch, making it suited for applications such as solid state relays, constant current sources, and linear amplifiers. The device also operates across a broad temperature range from -55°C to 150°C, suitable for harsh environments including telecom infrastructure and power supply circuits.

With a maximum gate-source voltage tolerance of ±20 V and forward voltage of 1.8 V, this MOSFET maintains stable operation and low power dissipation up to 740 mW. Its dimensions of approximately 5.33 mm height, 5.2 mm length, and 4.19 mm width provide a compact form factor for space-constrained designs.

High breakdown voltage and fast switching speeds enable advanced power electronics applications. Low input capacitance reduces switching losses and improves efficiency. High input impedance ensures minimal leakage current in circuits.

Robust packaging allows through-hole assembly in industrial electronics. Suitable for use in solid state relays, converters, amplifiers, and telecom systems. Wide operating temperature range supports diverse environmental conditions.

Compact TO-92 package with 3 pins fits standard PCB layouts for easy integration.

This Microchip MOSFET is ideal for industrial, manufacturing, electronics production, and power management applications requiring reliable, high-voltage, normally-on transistor technology.
