1N5276B-1

Single Zener Diodes Overview

The Microchip Technology 1N5276B-1 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 150 V with a tight tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Packaged in the DO-204AH (DO-35) axial through-hole format, it exhibits a maximum reverse leakage current of 100 nA at 114 V and a maximum Zener impedance of 1500 Ohms.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±5% tolerance on the 150 V nominal rating.
• Capable of handling high thermal loads with an extended operating temperature range up to 175°C.
• Constructed in a robust DO-204AH axial package suitable for through-hole mounting.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Voltage clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm that it denotes the ±5% tolerance variant rather than a standard ±10% version. Ensure the required package type matches the DO-204AH specification. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants in this series.

Single Zener Diodes Selection Notes

Select this component when a stable 150 V reference is required with tighter accuracy than standard industrial grades allow. The high-temperature capability makes it suitable for harsh environments where standard silicon limits might be exceeded. Verify that the 500 mW power rating aligns with the expected dissipation in the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281 series of Zener diodes manufactured by Microchip Technology. These components are widely used in discrete semiconductor applications requiring reliable voltage regulation. The 'B' suffix typically indicates a 5% tolerance, while the '-1' suffix further specifies the manufacturing or testing configuration within this family.

Single Zener Diodes Replacement Considerations

The 1N5276B is a parameter-equivalent alternative. Verify if the standard 1N5276 meets the ±5% tolerance requirement; otherwise, it may not be a direct functional substitute for precision applications.
