- Supports high temperature soldering conditions at 260°C for 10 seconds at terminals.
- Manufactured in compliance with EU RoHS 2.0 standards for lead-free materials.
Applications
- Voltage regulation circuits
- Overvoltage protection
- Reference voltage generation
Procurement Notes
Verify that the ordering suffix _R2_00001 corresponds to the specified reel packing configuration (5K pcs per 13-inch paper reel) as defined in the official datasheet. Confirm the manufacturer part number matches the 1N4728A series documentation to ensure correct electrical parameters and mechanical specifications are applied during procurement.
Selection Notes
Select this component when a 15 V unidirectional Zener regulator is required in a through-hole DO-41 package. Ensure the circuit design accommodates the 1 W power dissipation limit and verify that the 14 Ohm dynamic impedance meets the stability requirements of the application. Check thermal derating curves if operation exceeds standard ambient temperatures.
Part Context
This component is part of the 1N4728A series manufactured by Panjit International Inc., which covers a voltage range from 3.3 V to 68 V. The series utilizes silicon technology and is packaged in the standard DO-41 axial leaded format. The specific model provides a 15 V regulation point within this broader product family.
Replacement Considerations
Cross-reference with other manufacturers' 1N4744A equivalents to verify pinout compatibility and parameter tolerances. Ensure replacement parts meet the same DO-41 mechanical dimensions and 1 W power rating.
