1N5250B-TP

Single Zener Diodes Overview

The MCC 1N5250B-TP is a 500 mW Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 20 V with a ±5% tolerance, tested at a current of 6.2 mA. The device features a maximum Zener impedance of 25 Ohms and a reverse leakage current of 0.1 µA at 15 V. It operates within a temperature range of -55°C to +150°C and includes a positive temperature coefficient of +0.086 %/°C.

Single Zener Diodes Feature Summary

• Utilizes a glass encapsulated DO-35 axial leaded package for through-hole mounting.
• Provides stable voltage regulation with a 5% tolerance on the nominal breakdown voltage.
• Capable of high-temperature soldering at 260°C for 10 seconds at the terminals.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing from authorized distributors or directly from Micro Commercial Components. Counterfeit parts are a known industry risk; unauthorized sources do not provide warranty coverage. Confirm that the specific ordering suffix matches the required packaging format, as variations exist between tape-and-reel, ammo pack, and bulk configurations.

Single Zener Diodes Selection Notes

Select this component when a 20 V regulation point is required in a low-power application. Ensure the circuit design accommodates the specified 500 mW power dissipation limit and the resulting thermal derating requirements above 50°C. Verify that the DO-35 form factor fits the target PCB layout constraints.

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 indicates a 5% voltage tolerance, while the '-TP' suffix typically denotes the Tape and Reel packaging option.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the standard 1N5250B specification. Ensure any substitute maintains the 20 V nominal voltage, 500 mW power rating, and DO-35 package dimensions for mechanical compatibility.
