BZX84C5V1 SOT-23 Z2 Marking Application Fields
Voltage clamp protection
Used for protecting I/O ports and data lines (such as UART, I ² C) of ICs to prevent damage from overvoltage or static electricity.
Typical scenario: When connecting a 5V signal to a 3.3V MCU pin, connect BZX84C5V1 between the pin and ground, limiting the voltage to ≤ 5.1V.
Low voltage differential voltage reference
Provide a 5.1V reference voltage (accuracy typically ± 5%) for ADC, DAC, or comparator.
Suitable for low-power portable devices, such as reference sources for sensor modules.
Power supply stabilization assistance
In a simple voltage regulator circuit with small current (≤ 10mA), provide stable voltage for local circuits (such as bias circuits)
Switching power supply feedback compensation
Assist in adjusting feedback loops in flyback power supplies to improve stability.
Battery management and protection
Used for lithium battery protection board, limiting charging voltage or monitoring over voltage.
