Overview
The Central Semiconductor Corp 1N4717 TR TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It operates within the 1N4728A through 1N4764A series, providing a nominal Zener voltage of 100 V with a tolerance of ±5%. The device features a maximum power dissipation of 1 W and is housed in a DO-41 axial leaded package suitable for through-hole mounting. It supports an operating temperature range from -65°C to +200°C.
Feature Summary
- Provides stable voltage regulation at 100 V with standard 5% tolerance
- Capable of handling 1 W power dissipation for industrial reliability
- Constructed with high-temperature silicon for extended thermal operation
Applications
- Industrial voltage regulation circuits
- Commercial equipment power supplies
- Entertainment system power management
- Computer application voltage reference
Procurement Notes
Verify the specific electrical characteristics against the official datasheet for the 1N4728A series, as detailed parameters such as test current and impedance may vary by manufacturer lot. Confirm that the tin/lead termination style meets project requirements, noting that this component may not comply with RoHS directives. Ensure the DO-41 package dimensions align with the target PCB layout before finalizing procurement.
Selection Notes
Select this component when a 100 V Zener voltage is required in a through-hole configuration. The 1 W power rating allows for use in moderate current regulation scenarios without excessive heat sinking. The wide operating temperature range makes it suitable for environments where standard commercial-grade components might fail. Verify compatibility with existing circuit biasing conditions.
Part Context
This part belongs to the Central Semiconductor 1N4728A series of silicon Zener diodes. The series covers a voltage range from 3.3 V to 100 V, all sharing the same 1 W power dissipation and DO-41 package form factor. These devices are marketed for their high reliability in demanding industrial and commercial settings, offering consistent performance across the voltage spectrum.
Replacement Considerations
Cross-reference with other manufacturers' 1N4717A equivalents to ensure pinout and thermal characteristics match. Verify that substitute parts maintain the 100 V nominal voltage and 1 W power rating. Check for any differences in dynamic impedance or leakage current if precise regulation is critical.
