STMicroelectronics BAT42/BAT43 Small Signal Schottky DiodesThe STMicroelectronics BAT42 and BAT43 are small signal Schottky diodes. They are metal-to-silicon diodes within a DO-35 package. The main difference between the BAT42 and BAT43 is their static characteristics. Please refer to the product datasheet for full information.What is the repetitive peak reverse voltage?30VWhat is the storage and junction temperature range?-65ºC to +150ºCWhat are they used for?The BAT42 and BAT43 are designed for general purpose applications. They feature integrated excessive voltage protection, for example, against electrostatic discharge. Diodes and Rectifiers, STMicroelectronics
