Single Diodes datasheet and documents for BAT42

BAT42

Single Diodes Overview

The BAT42 is a general-purpose metal-to-silicon Schottky diode manufactured by STMicroelectronics. It features a single configuration in a DO-35-2 axial through-hole package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 30 V and an average forward current (If) of 200 mA. The device exhibits a low forward voltage drop (Vf) of 450 mV at rated current and a maximum reverse leakage current (Ir) of 500 nA. It supports a forward surge current (Ifsm) of 4 A and operates within a temperature range of -65°C to +125°C.

Single Diodes Feature Summary

Very low turn-on voltage for minimal conduction losses
Fast switching characteristics with negligible switching losses
Integrated protection against excessive voltage such as electrostatic discharge

Single Diodes Applications

General purpose signal rectification
Low voltage DC-DC converter circuits
Clamping applications in RF and audio systems

Single Diodes Procurement Notes

Verify component authenticity and datasheet revisions before integration, as the BAT42 is officially listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized secondary market distributors and ensure storage conditions comply with moisture sensitivity levels specified in the original production documentation to prevent lead frame degradation.

Single Diodes Selection Notes

Select this component for designs requiring low forward voltage drop and fast recovery in small-signal applications. Ensure the circuit design accommodates the 30 V reverse voltage limit and 200 mA continuous current rating. Verify that the DO-35-2 axial package fits the PCB layout constraints and thermal management requirements of the target assembly.

Single Diodes Part Context

The BAT42 belongs to the family of general-purpose Schottky barrier rectifiers produced by STMicroelectronics. It utilizes silicon technology to achieve superior switching performance compared to standard PN junction diodes. This component is part of a broader portfolio of discrete semiconductors designed for efficient power conversion and signal processing tasks.
