1N5256B-TP

Single Zener Diodes Overview

The MCC 1N5256B-TP is a single Zener diode with a nominal voltage of 30 V and a maximum DC power dissipation of 500 mW. It utilizes the DO-35 glass axial package and operates within a temperature range of -55°C to +150°C. The device features a 5% voltage tolerance, a maximum reverse leakage current of 100 µA at 23 V, and a Zener impedance of 49 Ohms at a test current of 4.2 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using planar die construction within a glass encapsulated package.
• Supports high-temperature soldering processes up to 260°C for ten seconds at the terminals.
• Includes cathode band marking for polarity identification and type number verification.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering suffix indicates compliance status. Confirm the specific packaging format matches project requirements, as options include tape and reel, ammo packing, or bulk carton quantities. Ensure procurement channels are authorized to guarantee genuine parts with full traceability and adherence to quality standards.

Single Zener Diodes Selection Notes

Select this component when a 30 V breakdown voltage is required in a through-hole configuration. Consider the 500 mW power rating and thermal derating characteristics above 50°C. Verify compatibility with operating temperatures ranging from -55°C to +150°C and ensure the low noise profile suits the application needs.

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 devices share common mechanical data, including the DO-35 case and solderable terminals compliant with MIL-STD-208.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5256B designation. Verify that alternative sources provide identical electrical parameters, specifically the 30 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure functional interchangeability.
