Overview
The STMicroelectronics BAR42FILM is a Schottky barrier rectifier diode designed for high-speed switching applications where low forward voltage drop and minimal reverse leakage are paramount. Its 30V reverse voltage and 100mA average forward current rating make it suitable for signal rectification and low-power voltage clamping. A critical design consideration for this device is managing its junction capacitance (typically 7pF at 1V), which can impact high-frequency performance; careful layout and impedance matching are essential to mitigate parasitic effects and ensure signal integrity, especially in sensitive RF circuits.
Key Features
- 30V DC Reverse Voltage (Vr)
