Description:
The BAS40-04 is an epitaxial silicon transistor designed for high-speed switching applications in compact electronic circuits. Enclosed in a SOT-23 package, this transistor offers efficient performance with a reverse voltage (Vr) rating of 40V and a maximum forward current (Io) of 200mA. Its low forward voltage (Vf) of 1V at 40mA ensures minimal power loss during operation. With a low reverse current (Ir) of 200nA at 30V, the BAS40-04 provides reliable switching characteristics suitable for a variety of applications requiring fast response times and low power consumption.

Features:
● Low Forward Voltage
● Fast Switching

Applications:
The BAS40-04 transistor is well-suited for the following applications:

● High-Speed Switching: Ideal for fast-switching circuits due to its low capacitance and high switching speed.
● Signal Rectification: Used in rectifier circuits to convert alternating current (AC) to direct current (DC).
● Signal Amplification: Amplifies weak signals in audio and radio frequency (RF) applications.
● Voltage Clamping: Provides voltage protection by clamping excessive voltage spikes.
● Temperature Sensing: Utilized in temperature sensing circuits due to its stable characteristics over temperature ranges.
