1N5261B-TP

Single Zener Diodes Overview

The MCC 1N5261B-TP is a single Zener diode housed in a DO-35 axial glass package. It provides a nominal Zener voltage of 47 V with a 5% tolerance, tested at a current of 2.7 mA. The device dissipates up to 500 mW and exhibits a maximum Zener impedance of 105 Ohms. Reverse leakage current is limited to 0.1 µA at 36 V. Operating temperatures range from -55°C to +150°C.

Single Zener Diodes Feature Summary

• Utilizes a glass encapsulation for high-temperature stability
• Features a cathode band marking for polarity identification
• Supports high-temperature soldering at 260°C for 10 seconds

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the authenticity of the component by checking for the specific cathode band marking and type number printed on the glass body. Ensure the ordering suffix matches the required packaging format, as the 'TP' designation indicates tape and reel packaging containing 10,000 pieces per reel. Confirm compliance requirements against the manufacturer's documentation.

Single Zener Diodes Selection Notes

Select this component when a precise 47 V reference is required within a through-hole design. The 5% tolerance suits general-purpose applications where tight precision is not critical. Consider the thermal derating curve if operating near the upper temperature limit to ensure power dissipation remains within safe limits.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series, covering a wide voltage range from 2.4 V to 75 V. All devices share the same DO-35 glass package and 500 mW power rating. The 'B' suffix specifically denotes a 5% voltage tolerance, distinguishing it from other tolerance variants in the family.

Single Zener Diodes Replacement Considerations

Cross-reference with Vishay or Microchip Technology equivalents such as 1N5261B. Verify that the replacement maintains the 47 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical compatibility.
