1N755D-1

Single Zener Diodes Overview

The Microchip Technology 1N755D-1 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device operates in the through-hole DO-35 (DO-204AH) axial package and supports a maximum DC power dissipation of 500 mW at +50°C. Key electrical specifications include a Zener impedance of 4 Ohms, a reverse leakage current of 2 µA at 5 V, and a forward voltage of 1.1 V at 200 mA. The component is qualified to MIL-PRF-19500/127 standards and functions within an operating temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Double plug construction with metallurgically bonded elements for enhanced reliability
• Hermetic sealing in a glass axial package suitable for harsh environments
• Qualified to military performance specification MIL-PRF-19500/127

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Temperature-compensated Zener references

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required qualification level, as variations exist between JAN, JANTX, and JANTXV grades. Confirm package type availability, as some variants are offered in MELF styles rather than the standard DO-35 axial leaded configuration. Ensure compliance with specific environmental or export control requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 7.5 V reference is required in high-reliability systems. The DO-35 package accommodates standard through-hole assembly processes. Consider the thermal derating curve for operation above +50°C to maintain safe power dissipation limits. Verify that the ±5% voltage tolerance aligns with circuit design constraints.

Single Zener Diodes Part Context

This part belongs to the 1N755 series of silicon Zener diodes manufactured by Microchip Technology. The series covers a range of voltage ratings from 2.4 V to 100 V. The 1N755 variant specifically targets the 7.5 V segment, providing a standardized solution for regulatory and reference needs across aerospace and industrial sectors.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JANTX1N755A-1 and JANTXV1N755D-1. These variants share identical electrical characteristics but differ in manufacturing grade and quality assurance levels defined by MIL-PRF-19500/127.
