Overview
The Central Semiconductor Corp 1N5301 TR TIN/LEAD is a silicon current regulator diode housed in the DO-7 (DO-204AA) axial leaded package. It provides a regulated current of 1.4 mA with a maximum knee impedance of 115,000 ohms and a maximum limiting voltage of 1.55 V. The device supports a peak operating temperature range from -55°C to +200°C and features an isolated case connection. The 'TR' suffix indicates tape and reel packaging, while 'TIN/LEAD' specifies the terminal plating composition.
Feature Summary
- Provides stable current regulation via silicon junction technology
- Features high dynamic impedance for effective current control
- Supports extreme thermal environments up to 200°C
Applications
- Constant current sources for LED biasing
- Current limiting protection circuits
- Voltage reference stabilization
Procurement Notes
Verify the specific ordering suffix requirements for the desired terminal finish when placing orders. Confirm that the 'TR' designation aligns with automated assembly equipment specifications. Ensure the requested quantity matches the manufacturer's standard tape and reel unit size to avoid partial reel handling issues during procurement processing.
Selection Notes
Select this component for applications requiring precise low-current regulation without active feedback loops. Verify that the 1.4 mA output meets the circuit load requirements. Ensure the DO-7 package dimensions fit the available board space and that the thermal rating accommodates the expected ambient conditions.
Part Context
This part belongs to the family of silicon current regulator diodes manufactured by Central Semiconductor. These devices are designed to replace resistors in constant current applications, offering superior stability against voltage fluctuations. The 1N5301 variant specifically targets the 1.4 mA regulation point within this product line.
Replacement Considerations
Check datasheets for alternative current regulator diodes with matching 1.4 mA ratings and DO-7 packages. Verify pinout compatibility and thermal characteristics before substituting.
