Overview
The Central Semiconductor Corp 1N4627 TR TIN/LEAD is a silicon unidirectional Zener diode housed in the DO-35 glass axial leaded package. It features a nominal Zener voltage of 6.2V with a maximum dynamic impedance of 1200 ohms and a maximum forward voltage of 1V. The device supports a power dissipation of 0.5W and operates within a temperature range of -55°C to +175°C junction temperature.
Feature Summary
- Utilizes a hermetically sealed glass axial leaded construction for environmental stability
- Capable of operation at elevated junction temperatures up to 175°C
- Designed for single-directional voltage regulation applications
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in electronic systems
- Clamping applications for signal lines
Procurement Notes
Verify the specific suffix 'TR' against the manufacturer's official datasheet to confirm tape-and-reel packaging versus bulk supply. Ensure the tin/lead terminal finish meets project requirements, as alternative lead-free versions may exist under different part numbers. Confirm availability status directly with Central Semiconductor or authorized distributors before finalizing design-in decisions.
Selection Notes
Select this component when a 6.2V Zener voltage is required in a standard DO-35 footprint. The high maximum operating temperature of 175°C makes it suitable for demanding thermal environments compared to standard plastic packages. Verify that the 1200 ohm dynamic impedance aligns with the noise and regulation specifications of the target circuit design.
Part Context
This component belongs to the 1N4627 series of small-signal Zener diodes manufactured by Central Semiconductor Corp. These devices are widely used in general-purpose electronics for voltage regulation and protection. The DO-35 package provides a compact form factor suitable for through-hole mounting on printed circuit boards.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4627 equivalents in DO-35 packages. Ensure replacement parts match the 6.2V Zener voltage, 0.5W power rating, and 1200 ohm dynamic impedance parameters.
