MMBZ5240B-7-F Description

Short technical summary and product information.

The MMBZ5240B-7-F is a 10V Zener diode from Diodes Incorporated, part of the MMBZ5221B-MMBZ5259B series. It features a planar die construction and is rated for 350mW power dissipation on standard FR-4 PCB. The device offers a nominal Zener voltage of 10V with ±5% tolerance, and a maximum impedance of 17Ω at the test current. Reverse leakage current is limited to 3µA at 8V reverse voltage, while forward voltage drop is 900mV at 10mA forward current.

 

The diode is designed for surface mount assembly and is housed in a SOT23-3 package (also known as TO-236-3 and SC-59). The molded plastic package is UL 94V-0 rated and uses a green molding compound. Terminals have a matte tin finish over Alloy 42 leadframe, ensuring solderability per MIL-STD-202. The device is rated for operation from -65°C to +150°C.

 

This component is fully RoHS3 compliant, lead-free, and halogen and antimony free (green device). It is Moisture Sensitivity Level 1 per J-STD-020, suitable for unlimited handling prior to reflow. Typical applications include voltage regulation, overvoltage protection, and clamping circuits in various electronic systems.
