Overview
The Microchip Technology 1N4684 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.3 V with a tolerance of 5%. The device operates in a DO-7-2 through-hole package and supports a maximum power dissipation of 500 mW. Electrical characteristics include a maximum reverse leakage current of 7.5 uA at the test current of 50 uA, a forward voltage of 1.1 V, and a maximum forward current of 200 mA. The component is rated for an operating temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation with a nominal 3.3 V Zener breakdown voltage.
- Capable of handling high thermal loads with a maximum junction temperature rating of +175 C.
- Constructed with a hermetically sealed glass body for environmental protection.
Applications
- Voltage reference circuits
- Overvoltage protection stages
- Clamping applications
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and compliance status. Ensure the selected variant matches the required RoHS designation and lead finish specifications for the target assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a precise 3.3 V reference is required in a through-hole configuration. Consider the 5% voltage tolerance and 500 mW power dissipation limits during circuit design. Evaluate the -65 C to +175 C operating range to ensure suitability for extreme environmental conditions compared to standard commercial grade alternatives.
Part Context
The 1N4684 belongs to the standard Zener diode family manufactured by Microchip Technology. It falls under the Diodes & Rectifiers subcategory and is classified as a Voltage Regulator. This component utilizes silicon technology and is housed in a DO-7-2 axial leaded package, distinguishing it from surface-mount variants within the broader product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Microchip cross-reference guides or authorized distributor databases for verified equivalent components.
