What is BAS70-05?

BAS70-05 is a low current, small package, common cathode structure schottky diode device, integrating two diodes with independent anodes and shared cathodes. Its internal connection method makes it very suitable for applications that require two signal convergence, common cathode rectification or clamping protection.

Mechanical Data

  • SOT-23 Small Outline Plastic Package
  • Polarity: Color band denotes cathode end
  • Mounting Position: Any

Core Featuers

  • Low forward voltage drop (VF ≈ 0.3V): more power-saving and less heat loss than ordinary silicon diodes
  • Ultra-fast switching speed: suitable for high-frequency signals or digital logic circuits
  • Common cathode structure: can simplify applications such as rectification and logical "or" connection
  • Compact package: suitable for high-density, miniaturized PCB design

Applications

  • Logic circuit "OR" function realization
    Connect the two output ends through the two anodes of BAS70-05, and use the common cathode as the output to realize a simple "OR" logic output: used for level compatibility, bus multi-driver and other occasions.
  • Dual input signal rectification
    Suitable for low-power AC input rectification, such as the positive and negative half cycles pass through two diodes respectively, and finally output from the common cathode: can be used for low-power DC extraction, small signal energy collection and other scenarios.
  • Interface protection / ESD auxiliary clamp
    Can be used in audio, GPIO, analog input and other circuits to prevent external voltage from exceeding the allowable range

Summary

The BAS70-05 is a device with a simple structure but wide application. With its common cathode dual Schottky structure, it can replace two separate diodes in many occasions, which not only saves space, but also improves the neatness and response speed of the circuit.
