1N4759AP/TR12

Single Zener Diodes Overview

The Microchip Technology 1N4759AP/TR12 is a silicon 1-watt Zener diode in the 1N4728A through 1N4764A series. It provides voltage regulation at a nominal Zener voltage of 62 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a plastic DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 125 Ohms at a test current of 4.0 mA, a maximum reverse current of 5 µA, and a maximum regulator current of 14 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability standards

Single Zener Diodes Applications

• Voltage regulation circuits requiring 62 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 62 V Zener voltage and 1 W power dissipation rating. Confirm the package type is the plastic DO-41 variant and ensure the tape and reel packaging aligns with automated assembly requirements. Cross-reference manufacturer documentation for any updates regarding RoHS compliance or military screening prefixes if applicable to your design specifications.

Single Zener Diodes Selection Notes

Select this component when a 62 V Zener diode with a 1 W power rating is required in an axial-lead plastic package. The 5% voltage tolerance suits general regulation tasks where tighter precision is not critical. Consider the thermal resistance of 45 °C/W junction-to-lead for heat dissipation planning. Ensure the operating environment stays within the specified -65°C to +150°C temperature range for reliable performance.

Single Zener Diodes Part Context

This component belongs to the widely used 1N47xxA series of silicon Zener diodes, originally standardized by JEDEC. The 'P' suffix indicates a plastic encapsulated body, offering lower thermal resistance compared to glass-body options. The 'TR' suffix denotes tape and reel packaging for high-volume manufacturing, while the 'e3' suffix typically signifies lead finish compliance, though availability varies by manufacturer lot.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4759A parts in the DO-41 package. Verify that replacement units maintain the 62 V nominal voltage, 1 W power rating, and ±5% tolerance. Ensure the alternative component meets the same thermal and electrical specifications for direct integration into existing designs.
