Overview
The 1N4744A TR TIN/LEAD is a single standard Zener diode manufactured by Central Semiconductor Corp. It features a 15 V Zener voltage with a 1 W power dissipation rating. The device utilizes a DO-41 through-hole package and operates with a maximum reverse leakage current of 5 uA at a test current of 17 mA. Key electrical parameters include a Zener impedance of 17 Ohms and a knee voltage of 12.2 V. The component is supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation at 15 V for circuit protection applications
- Designed for through-hole mounting using the DO-41 axial leaded package
- Constructed with silicon unidirectional voltage regulator technology
Applications
- Voltage reference circuits requiring 15 V stability
- Overvoltage protection in low-power electronic systems
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering suffix to confirm the tin/lead plating and tape and reel packaging configuration. Ensure compatibility with RoHS directives if lead-free variants are required, as this specific part number indicates tin/lead composition. Confirm availability status as manufacturing lifecycles may change.
Selection Notes
Select this component when a 15 V Zener voltage with 1 W power handling is required in a through-hole assembly. The DO-41 package suits automated pick-and-place processes due to the tape and reel format. Consider the 17 Ohm impedance for precision requirements in voltage regulation tasks.
Part Context
This part belongs to the 1N47xx series of single Zener diodes from Central Semiconductor. These components are widely used for general-purpose voltage regulation and clipping. The 1N4744A variant specifically targets the 15 V market segment within the 1 W power class family.
Replacement Considerations
Check for direct equivalents such as the 1N4744A BK PBFREE or other 1N4744A variants from different manufacturers. Verify that substitute parts match the 15 V Zener voltage, 1 W power rating, and DO-41 package dimensions.
