Overview
The Central Semiconductor Corp 1N4682 TR TIN/LEAD is a single axial lead Zener diode housed in a DO-35 package. It features a nominal Zener voltage of 2.7 V with a tolerance of ±5%, resulting in a range of 2.565 V to 2.835 V. The device supports a power dissipation of 500 mW and operates within a temperature range of -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 1 V and a test current of 50 µA.
Feature Summary
- Provides stable voltage regulation through a single Zener diode configuration
- Utilizes a tin/lead plated finish for reliable soldering connections
- Designed for through-hole mounting in standard axial packages
Applications
- Voltage reference circuits requiring low voltage stability
- Overvoltage protection for sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific ordering suffix 'TIN/LEAD' to ensure compliance with material requirements, as this indicates the plating composition. Confirm that the DO-35 package dimensions match your PCB footprint constraints. Ensure the 500 mW power rating is sufficient for your thermal environment. Check for RoHS status if lead-free compliance is mandatory for your assembly process.
Selection Notes
Select this component when a precise 2.7 V reference is needed with tight tolerance. Consider the high operating temperature limit of 200 °C for harsh environments. Evaluate the low leakage current specification for high-impedance circuit designs. Compare against other Zener voltages in the 1N468x series if alternative reference levels are required.
Part Context
This part belongs to the 1N468x series of glass-passivated Zener diodes manufactured by Central Semiconductor. These devices are characterized by their robust construction and wide operating temperature range. The series offers various voltage options while maintaining consistent power dissipation and package standards across the product line.
Replacement Considerations
Direct substitutes may include other manufacturers' 1N4682 equivalents with identical 2.7 V Zener voltage and DO-35 packaging. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement part meets the same voltage tolerance and leakage current specifications.
