Introduction

A 1N4249GP-M3/73 is a single rectifier diode with a maximum reverse voltage of 73V and maximum peak inverse current of 300 mA. It has a minimum thermal resistance junction to ambient of 0.15°C/W. This diode is extensively used for signal detection and switching applications and has a low forward voltage drop of 0.15 Volts.

Application Field

The 1N4249GP-M3/73 is typically used in signal detection and switching applications. It is also useful for general rectification applications, such as rectifying AC mains power or from automotive alternators. The low forward voltage drop, fast switching speed and excellent surge capability make it ideal for these applications. It is also designed to protect circuits and components against reverse-voltage spikes and over-voltage transients.

Working Principle

The 1N4249GP-M3/73 uses a PN-junction to allow only conventional current to flow in one direction, while blocking current in the opposite direction. It has a forward voltage drop of 0.15V and a reverse voltage of up to 73V.In normal forward operation, the diode is forward biased and a small voltage drop occurs across it. This forward bias increases the current conduction until the diode is saturated and the voltage drop is equal to the forward bias voltage.In reverse operation, the diode is reverse biased and no current flows across it. It instead acts as an open circuit, blocking any current from flow in the reverse direction. It can handle up to 73V in reverse operation.
