What is BAS70-04?

BAS70-04 is a dual schottky diode, whose two diode anodes share one pin, so it is called "common anode structure". This type of structure is particularly suitable for use in situations where bidirectional limiting, input protection, level clamping, etc. are required.

Mechanical Data

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

Core Featuers

  • Low forward voltage drop: reduce energy consumption and improve efficiency
  • Fast switching speed: suitable for high-speed digital circuits
  • Common anode dual diode structure: greatly improve circuit flexibility
  • Small size: very suitable for portable and embedded devices

Applications

  • Input protection (clamp circuit):
    Prevent external signals from exceeding the power supply or ground level at the input of MCU or logic circuit
  • USB, GPIO interface protection:
    Applicable to communication interfaces such as GPIO, I²C, SPI, etc., to prevent electrostatic discharge (ESD) or accidental high voltage from burning the chip.
  • Level conversion:
    Simple unidirectional or bidirectional level adjustment between different voltage systems.

Summary

Although BAS70-04 is just a small three-pin diode, it has outstanding performance in modern electronic design due to its common anode structure, low voltage drop, fast response, and small size. Especially in applications with extremely high performance and volume requirements such as portable devices, high-speed communications, and interface protection, BAS70-04 is a highly recommended device.
