MMBZ5252B Description

Short technical summary and product information.

The MMBZ5252B is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 24V with a tolerance of ±5%, ensuring precise voltage reference. The diode can dissipate up to 300mW of power, making it suitable for low-power clamping and regulation circuits.

 

The device offers a maximum Zener impedance of 33Ω at the test current, providing stable regulation characteristics. Reverse leakage current is limited to 100nA at 18V, ensuring low power loss in standby conditions. The forward voltage is typically 900mV at 10mA forward current.

 

This Zener diode is available in a surface-mount SOT-23 package (alternatively TO-236-3, SC-59), which is ideal for compact PCB designs. The SOT-23 package is widely used in consumer and industrial electronics for its small footprint and ease of automated assembly.
