MMBZ5221B-7-F Description

Short technical summary and product information.

The MMBZ5221B-7-F is a 2.4V Zener diode from Diodes Incorporated, designed for general-purpose voltage regulation and protection applications. It features a nominal Zener voltage of 2.4V with ±5% tolerance, a maximum power dissipation of 350mW, and a maximum impedance of 30Ω. The forward voltage is 900mV at 10mA, and reverse leakage current is 100µA at 1V. The device operates over a temperature range of -65°C to 150°C.

 

The diode is housed in a surface-mount SOT-23-3 package, making it suitable for automated assembly processes. It is RoHS3 compliant, lead-free, and halogen-free, with a moisture sensitivity level of 1 per J-STD-020. The terminals have a matte tin finish.

 

Typical applications include voltage regulation, overvoltage clamping, and reference voltage generation in low-power circuits. The 350mW power dissipation allows use in compact designs where space is limited.
