Overview
The Central Semiconductor Corp 1N4680 TR TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 2.2 V with a 5% tolerance, housed in a DO-7 (DO-204AA) axial-leaded glass package. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 4 µA and a test current of 50 µA.
Feature Summary
- Provides stable voltage regulation at low voltage levels using a 2.2 V Zener reference.
- Constructed with hermetically sealed glass axial-leaded DO-7 packaging for environmental protection.
- Capable of operating reliably across an extended industrial temperature range up to 175°C.
Applications
- Low-voltage reference circuits requiring precise 2.2 V regulation.
- Overvoltage protection stages in sensitive electronic systems.
- General-purpose voltage clamping in signal processing paths.
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the requested variant matches the required JEDEC registration and thermal specifications for the intended application environment.
Selection Notes
Select this component when a 500 mW axial-leaded Zener diode with a 2.2 V breakdown voltage is required. Consider the DO-7 package constraints and the specified 5% tolerance for circuit design accuracy. Evaluate the maximum reverse leakage current and impedance parameters against load requirements.
Part Context
This part belongs to the standard 1N4678 through 1N4717 series of small-signal Zener diodes manufactured by Central Semiconductor. These components are widely utilized in general electronics for basic voltage regulation tasks where moderate power handling and standard axial mounting are sufficient.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4680 equivalents in DO-7 packages. Verify that substitute parts maintain the 2.2 V Zener voltage, 500 mW power rating, and compatible pinout dimensions for direct board replacement.
