1N5276B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5276B-1/TR 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 is rated for a maximum power dissipation of 500 mW and utilizes the DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 114 V, a forward voltage of 1.5 V at 200 mA, and a maximum Zener impedance of 1500 Ohms. It operates within a junction temperature range of -65°C to 175°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 150 V nominal breakdown voltage and ±5% tolerance.
• Engineered for high-temperature reliability with an extended operating range up to 175°C.
• Utilizes a standard DO-204AH (DO-35) axial leaded package for robust through-hole mounting.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Clamping applications in signal processing

Single Zener Diodes Procurement Notes

Verify that the specific suffix '-1' corresponds to the required ±5% tolerance variant, as other suffixes may indicate different tolerances or packaging formats. Confirm RoHS compliance status, as this specific part number is listed as non-RoHS in official documentation. Ensure the reel packaging format aligns with automated assembly requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 150 V reference is required with tighter than standard tolerance specifications. The DO-35 package is suitable for general-purpose boards where space constraints are minimal. Consider the 1500 Ohm impedance value for noise-sensitive designs, as higher impedance may impact regulation stability under varying load conditions compared to lower impedance alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N5276 series of 1/2 Watt Zener Diodes manufactured by Microchip Technology. The series covers a wide range of voltage ratings from low voltages up to 200 V. The 'B-1' designation typically indicates a specific tolerance band and manufacturing revision within the broader 1N5276 family, ensuring consistency with legacy MIL-spec equivalents while meeting modern manufacturing standards.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent substitutes include the 1N5276B and 1N5276B-1. Verify that any replacement maintains the 150 V Zener voltage and ±5% tolerance. Ensure the substitute supports the same DO-35 package and thermal characteristics to maintain board compatibility and performance integrity.
