1N5239DRL

Single Zener Diodes Overview

The Motorola 1N5239DRL is a silicon unidirectional voltage regulator diode housed in the DO-35 glass axial leaded package. It provides a nominal Zener voltage of 9.1 V with a maximum power dissipation of 0.5 W. The device features a single diode configuration and operates within a temperature range of -65 °C to 200 °C. Key electrical characteristics include a knee impedance of up to 600 Ω and an isolated case connection.

Single Zener Diodes Feature Summary

• Hermetically sealed double slug type construction for environmental stability
• Metallurgically bonded internal structure ensuring reliable performance
• Corrosion-resistant external surfaces with readily solderable leads

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Voltage reference applications requiring stable potential
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'DRL' against official NXP or onsemi documentation, as standard datasheets often list 'B' or 'D' variants. Confirm that the ordering code corresponds to the correct tape and reel packaging format intended for automated assembly processes rather than bulk supply.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V reference is required in a through-hole DO-35 package. Ensure the circuit design accommodates the 0.5 W power rating and the specified operating temperature limits. Verify compatibility with the required knee impedance specifications for the specific application load.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of 500 mW DO-35 Glass Zener Voltage Regulator Diodes originally manufactured by Motorola Semiconductor Products. The series covers a wide voltage range from 1.8 to 200 Volts. Motorola's semiconductor division was later acquired by NXP Semiconductors, and production rights for many legacy parts are now managed by onsemi.

Single Zener Diodes Replacement Considerations

Cross-reference with 1N5239B or 1N5239D for equivalent electrical specifications. Check manufacturer-specific suffixes for packaging differences such as bulk versus reel.
