1N5225B-TP

Single Zener Diodes Overview

The 1N5225B-TP is a single Zener diode manufactured by Micro Commercial Components (MCC) in the DO-35 axial leaded package. It provides a nominal Zener voltage of 3.0 V with a 5% tolerance, tested at a current of 20 mA. The device supports a DC power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a maximum Zener impedance of 29 Ohms, a reverse leakage current of 50 µA, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Utilizes a glass encapsulated DO-35 package for robust through-hole mounting.
• Features high-temperature soldering capability up to 260°C for ten seconds at the terminals.
• Includes a cathode band marking for correct polarity identification.

Single Zener Diodes Applications

• Voltage regulation circuits requiring low voltage references.
• Clipping and clamping applications in signal processing.
• Protection against overvoltage transients in electronic systems.

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing exclusively from MCC or authorized distributors to avoid counterfeits. Confirm the specific suffix designation matches the required packaging format, such as tape and reel or bulk. Ensure that the procurement specifications align with the documented electrical characteristics and operating temperature limits before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a precise 3.0 V reference is needed in a standard axial package. Consider the 5% voltage tolerance and 29 Ohm impedance for circuit stability requirements. Evaluate the 500 mW power dissipation limit and derating curve for thermal management in the intended application environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V, all housed in the same DO-35 glass package. The 'B' suffix specifically denotes a 5% tolerance on the nominal Zener voltage, distinguishing it from tighter tolerance variants.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 3.0 V Zener voltage, 500 mW power rating, and DO-35 package. Verify that substitute components meet the same 29 Ohm impedance and 50 µA leakage current specifications to ensure circuit compatibility.
