1N5228B-TP

Single Zener Diodes Overview

The MCC 1N5228B-TP is a single silicon Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 3.9 V with a 5% tolerance, tested at a current of 20 mA. The device supports a maximum DC power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 1 V and a Zener impedance of 23 Ohms.

Single Zener Diodes Feature Summary

• Utilizes a glass axial-leaded DO-35 package for high-temperature soldering capability
• Provides stable voltage regulation with a negative temperature coefficient below 5V
• Features a cathode band marking for polarity identification

Single Zener Diodes Applications

• Voltage reference circuits requiring low-voltage stability
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the component authenticity by checking for the specific MCC branding and cathode band markings on the DO-35 glass body. Confirm that the suffix 'TP' indicates lead-free and RoHS compliance status as defined by the manufacturer's ordering information. Ensure sourcing from authorized distributors to guarantee traceability and adherence to quality standards.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V regulation point is required in through-hole designs. The DO-35 package accommodates standard PCB drilling patterns. Consider the 500 mW power rating and derating curve above 50°C during thermal analysis. The negative temperature coefficient is suitable for applications where voltage decreases slightly with rising ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V. The 'B' suffix specifically denotes a 5% voltage tolerance, distinguishing it from tighter tolerance variants.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5228B designation in the DO-35 package. Verify that substitute parts match the 3.9 V nominal voltage, 500 mW power dissipation, and 5% tolerance specifications to ensure circuit compatibility.
