Product Details:

Overview

The STMicroelectronics BAR43FILM is a Schottky rectifier diode designed for efficient signal rectification and low-voltage drop applications. Its key operational characteristic is the exceptionally low forward voltage (Vf) of 1V at 100mA, crucial for minimizing power dissipation in sensitive circuits. A critical design consideration when employing such low Vf diodes is their susceptibility to leakage current at elevated reverse voltages; the BAR43FILM exhibits a low reverse leakage of 500 nA at 30V, balancing speed with minimal quiescent power draw.

Key Features

Maximum DC Reverse Voltage (Vr): 30 V
Average Rectified Current (Io): 100 mA
Maximum Forward Voltage (Vf): 1 V @ 100 mA
Reverse Recovery Time (trr): 5 ns
Junction Temperature: 150°C (Max)
Package: SOT-23-3 (TO-236-3, SC-59)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

High-frequency signal detection in RF mixers and demodulators.
Low-power voltage clamping and transient suppression in sensitive ICs.
Reverse polarity protection for battery-powered portable devices.
Output rectification in low-voltage, high-efficiency DC-DC converters.
