1N4683-TP

Overview

The 1N4683-TP is a 500mW silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 3.0V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65°C to 200°C and utilizes a DO-35 axial through-hole package. Key electrical characteristics include a maximum forward voltage of 1.5V at 100mA, a reverse leakage current of 0.8µA at 2V, and a maximum Zener impedance of 85 Ohms.

Feature Summary

• Double slug type construction for high reliability
• Hermetically sealed glass case
• Very sharp reverse characteristic

Applications

• Voltage regulation circuits
• Voltage reference applications
• Protection against overvoltage transients

Procurement Notes

Verify the authenticity of the component by checking for authorized distributor status or direct MCC purchase channels. Confirm that the part matches the specific suffix requirements for packaging, such as tape and reel or bulk options, as these do not alter the electrical function but affect handling procedures.

Selection Notes

Select this component when a precise 3.0V reference is required in low-power designs. Ensure the circuit can accommodate the specified thermal resistance and power dissipation limits. Verify that the operating environment stays within the defined storage and junction temperature ranges for optimal performance.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes from Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, all sharing similar mechanical and thermal specifications while varying in nominal breakdown voltage and associated impedance values.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4683 variants. Ensure replacement parts match the 500mW power rating, DO-35 package dimensions, and ±5% voltage tolerance to maintain circuit integrity.
