BAT43 Description

Short technical summary and product information.

The BAT43 is a through-hole Schottky diode designed for low-voltage, high-speed switching applications. It features a maximum reverse voltage of 30V and an average rectified current rating of 200mA. The forward voltage is a maximum of 1V at 200mA, ensuring low power dissipation. With a reverse recovery time of just 5ns, this diode is well-suited for fast switching circuits. The reverse leakage current is limited to 500nA at 25V, and the junction capacitance is typically 7pF at 1V and 1MHz, making it suitable for high-frequency designs. The diode operates over a junction temperature range of -65°C to 125°C. It is offered in the DO-35 package (also available as DO-204AH axial), which is compatible with through-hole mounting for robust assembly.
