1N5270B-TP

Single Zener Diodes Overview

The MCC 1N5270B-TP is a glass-passivated Zener diode in the DO-35 axial package, rated for 500 mW DC power dissipation. It provides a nominal Zener voltage of 91 V at a test current of 1.4 mA with ±5% tolerance. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 69 V and a maximum Zener impedance (Zzt) of 400 Ohms at the test current. The device operates within an ambient temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Glass passivation protects the PN junction against mechanical damage and moisture.
• High thermal stability supports soldering at 260°C for 10 seconds.
• Lead-free finish complies with RoHS directives.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix '-TP' corresponds to Tape & Reel packaging containing 10,000 pieces per reel. Confirm that the 'B' suffix guarantees ±5% voltage tolerance across all listed electrical parameters. Ensure compliance requirements match the lead-free status noted in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a precise 91 V reference is required with tight ±5% tolerance. The DO-35 package suits through-hole designs needing 500 mW dissipation. Verify that the 400 Ohm impedance meets circuit sensitivity requirements compared to lower-voltage alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N5268 through 1N5276 series, covering voltages from 82 V to 150 V. All devices share identical physical dimensions and thermal characteristics, differing only in breakdown voltage specifications.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering 1N5270B equivalents in DO-35 packages. Ensure substitute parts maintain the 91 V nominal voltage, 500 mW rating, and ±5% tolerance limits.

Single Zener Diodes FAQ

What does the 'B' suffix indicate?

The 'B' suffix designates a voltage tolerance of ±5%, ensuring guaranteed limits on all six electrical parameters including Zener impedance and leakage current.

How is the temperature coefficient defined for this part?

The temperature coefficient is measured at the rated test current (1.4 mA) between 25°C and 125°C, resulting in a value of +0.099 %/°C.
