1N5298RL/TR

Overview

The Microchip Technology 1N5298RL/TR is a current regulator diode designed for through-hole mounting in the DO-7 axial package. It operates with a maximum voltage of 100V and dissipates up to 500mW of power. The device regulates current at 1.21mA with a maximum limit voltage of 1.4V. It functions within a temperature range of -65°C to +175°C junction temperature. This component is supplied in tape and reel packaging, suitable for automated assembly processes.

Feature Summary

• Provides stable current regulation across a wide operating temperature range
• Utilizes a standard DO-7 axial leaded package for through-hole integration
• Designed for high reliability applications requiring consistent current control

Applications

• Biasing circuits for transistors and other semiconductor devices
• Constant current sources for LED drivers and indicator lamps
• Protection circuits requiring fixed current limiting

Procurement Notes

Verify the specific suffix RL/TR confirms the tape and reel packaging format required for your automated assembly line. Confirm that the manufacturer designation aligns with Microchip Technology standards. Ensure the part number matches the exact electrical specifications needed for your design. Check for any recent PCN notifications regarding assembly site or labeling changes before placing orders.

Selection Notes

Select this component when a precise 1.21mA regulation is required within a 100V maximum voltage constraint. Consider the DO-7 package dimensions for PCB layout compatibility. Evaluate the thermal management requirements given the 500mW power dissipation capability. Compare against other current regulator diodes if different current levels or package types are more suitable for the application constraints.

Part Context

This part belongs to the 1N5298 series of current regulator diodes manufactured by Microchip Technology. The series offers various regulated current values within similar voltage and power constraints. The 1N5298 variant specifically targets the 1.21mA regulation point. Other variants in the family provide different current levels for diverse circuit requirements.

Replacement Considerations

Direct substitutes include other 1N5298 series parts from Microchip such as 1N5298-1, though packaging may differ. Verify equivalent electrical parameters like regulated current and maximum voltage before substitution. Cross-reference with generic current regulator diodes only if pinout and package dimensions match exactly.
