1N5258B-TP

Single Zener Diodes Overview

The MCC 1N5258B-TP is a single silicon planar Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 36 V with a 5% tolerance at a test current of 3.4 mA. The device dissipates up to 500 mW DC power and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA, a Zener impedance of 70 Ohms, and a positive temperature coefficient of +0.093 %/°C.

Single Zener Diodes Feature Summary

• Utilizes a glass passivated junction for high-temperature stability and reliability.
• Features a standard DO-35 axial leaded package suitable for through-hole mounting.
• Designed for high-temperature soldering compatibility at 260°C for 10 seconds.

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the authenticity of the component by checking for the cathode band marking and part number imprint on the glass body. Ensure procurement from authorized distributors to avoid counterfeit parts. Confirm that the specific suffix 'TP' indicates tape and reel packaging containing 10,000 pieces per reel as defined in the manufacturer's ordering information.

Single Zener Diodes Selection Notes

Select this component when a precise 36 V reference is required in a through-hole design. The 5% tolerance ('B' suffix) offers tighter voltage control compared to standard variants. Consider the 70 Ohm impedance and low leakage current for applications requiring stable performance under varying load conditions.

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, all sharing the same DO-35 glass package and thermal characteristics. The 'B' suffix specifically denotes a 5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 36 V Zener voltage, 500 mW power dissipation, DO-35 package, and 5% tolerance specifications.
