1N4783

Overview

The Microchip Technology 1N4783 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 8.5 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and a maximum impedance (Zzt) of 100 Ohms. It operates within a temperature range of -55°C to +100°C and utilizes a DO-35 axial through-hole package.

Feature Summary

• Provides stable voltage regulation at an 8.5 V nominal level
• Suitable for through-hole mounting in compact circuits
• Operates reliably across extended industrial temperature ranges

Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate variations in packaging or compliance status. Confirm that the required Zener voltage and power dissipation ratings align with the circuit design specifications before procurement. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a precise 8.5 V reference is needed in a standard axial leaded package. Consider the 500 mW power rating and 100 Ohm impedance limits during thermal and load analysis. Verify compatibility with the intended operating temperature environment and ensure the through-hole footprint matches the PCB layout requirements.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used in discrete semiconductor applications requiring reliable voltage clamping or regulation. The DO-35 package provides a standardized form factor for automated assembly and manual soldering processes in electronic manufacturing.

Replacement Considerations

Cross-reference with other manufacturers' 1N4783 equivalents to verify pinout and electrical parameter compatibility. Ensure substitute parts meet the same 8.5 V Zener voltage and 500 mW power dissipation requirements.
