CMHZ5234B TR PBFREE

Single Zener Diodes Overview

The CMHZ5234B TR PBFREE is a surface mount silicon Zener diode from the Central Semiconductor CMHZ5221B series, housed in an SOD-123 package. It provides a nominal Zener voltage of 6.2 V with a ±5% tolerance (suffix B). The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical parameters include a maximum Zener impedance of 7.0 Ω at IZT and 1000 Ω at IZK, a reverse leakage current of 5.0 µA at 4.0 V, and a temperature coefficient of +0.045 %/°C.

Single Zener Diodes Procurement Notes

Verify the specific revision level of the datasheet when sourcing, as manufacturing updates may occur. Confirm that the PBFREE suffix aligns with environmental compliance requirements for your assembly process. Check for any End-of-Life notices or discontinuation alerts directly from Central Semiconductor before finalizing procurement plans to ensure supply continuity.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with 5% tolerance is required in a compact SOD-123 footprint. Ensure the circuit design accounts for the positive temperature coefficient of +0.045 %/°C if operating over wide thermal ranges. Verify that the 500 mW power dissipation rating is sufficient for the expected junction temperature and ambient conditions.

Single Zener Diodes Part Context

This part belongs to the CMHZ5221B through CMHZ5267B series of surface mount silicon Zener diodes. The series covers a voltage range from 2.4 V to 75 V, all sharing the same SOD-123 mechanical outline and 500 mW power rating. The 'TR' suffix indicates tape and reel packaging, while 'PBFREE' denotes lead-free terminal finish.
