Overview
The Central Semiconductor Corp 1N4708 BK TIN/LEAD is a silicon unidirectional voltage regulator diode housed in a DO-35 through-hole package. It features a nominal Zener voltage of 22 V with a maximum tolerance of 5%. The device has a maximum power dissipation of 0.25 W and operates within a temperature range up to 175 °C. It utilizes a tin-plated terminal finish and is designed for single configuration applications requiring stable voltage reference or regulation.
Feature Summary
- Provides stable voltage regulation at a nominal 22 V level
- Utilizes silicon epitaxial planar construction for reliability
- Features tin-plated leads for through-hole mounting compatibility
Applications
- Voltage reference circuits
- Overvoltage protection
- General purpose regulation
Procurement Notes
Verify the specific suffix requirements against the manufacturer's current datasheet, as packaging and plating options may vary. Confirm RoHS compliance status directly with the supplier documentation. Ensure the DO-35 package dimensions match the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 22 V Zener voltage is required in a low-power through-hole application. The 0.25 W power rating limits its use to low-current regulation scenarios. Consider the 5% voltage tolerance for precision requirements. Verify that the operating temperature range meets the environmental conditions of the intended system design.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes manufactured by Central Semiconductor. These components are widely used in electronic circuits for voltage stabilization. The DO-35 package is a common axial leaded form factor suitable for general-purpose electronics manufacturing and repair applications.
Replacement Considerations
Cross-reference with other manufacturers' 1N4708 equivalents. Verify electrical parameters such as Zener voltage, power dissipation, and package type match the original specifications before substitution.
