CMDZ5243B BK PBFREE

Single Zener Diodes Overview

The Central Semiconductor CMDZ5243B BK PBFREE is a surface-mount silicon Zener diode housed in an SOD-323 package. It provides a nominal Zener voltage of 13 V with a 5% tolerance, operating within a range of 12.35 V to 13.65 V at a test current of 9.5 mA. The device dissipates up to 250 mW and maintains a maximum reverse leakage current of 0.5 µA at 9.9 V. It supports an operating temperature range from -65 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix required for your application. The 'BK' designation indicates bulk packaging, while 'TR' indicates tape and reel. Confirm whether lead-free or tin/lead plating is needed by checking if the 'PBFREE' suffix is present. Ensure compatibility with the SOD-323 footprint before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 13 V reference is required in a compact surface-mount design. Consider the 250 mW power dissipation limit and the -65 °C to +150 °C operating range. Verify that the SOD-323 package dimensions fit the intended PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the CMDZ5221B through CMDZ5261B series of surface-mount silicon Zener diodes. These devices are characterized by 5% voltage tolerance and are designed for use in space-constrained electronic circuits requiring stable voltage regulation across various environmental conditions.

Single Zener Diodes Replacement Considerations

Central Semiconductor has transitioned SOD-323 devices to End of Life status. The suggested replacement is the CMDZ5243BF BK PBFREE, which utilizes the SOD-323F case instead of the original SOD-323 package.
