1N4759AE3/TR13

Overview

The Microchip Technology 1N4759AE3/TR13 is a single Zener diode with a nominal voltage of 62 V and a power dissipation rating of 1 W. It features a ±5% voltage tolerance and a maximum Zener impedance of 125 Ohms. The device operates within a temperature range of -65°C to +150°C, with a maximum reverse leakage current of 5 µA. Packaged in the DO-41 axial leaded format, it is supplied in reel packaging for automated surface mount or through-hole assembly processes.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Designed for high-temperature operation up to 150°C
• Utilizes an axial DO-41 package for through-hole mounting

Applications

• Voltage reference circuits requiring 62 V stability
• Overvoltage protection stages in power supplies
• Clamping applications in electronic signal conditioning

Procurement Notes

Verify the specific suffix 'TR13' indicates reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology, noting historical lineage from Microsemi. Ensure the component meets RoHS compliance standards as indicated by the 'e3' suffix. Cross-reference the part number with official Microchip documentation to confirm current lifecycle status and availability before finalizing procurement plans.

Selection Notes

Select this component when a precise 62 V Zener reference is required with low leakage current specifications. The 1 W power rating supports moderate current handling in thermal-constrained environments. The wide operating temperature range makes it suitable for industrial applications where ambient conditions fluctuate significantly between extreme cold and heat.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes, widely used for basic voltage regulation tasks. The 'e3' suffix denotes lead-free composition, adhering to environmental directives. The TR13 packaging variant facilitates high-volume manufacturing integration, distinguishing it from bulk or tape-and-reel alternatives within the same electrical specification family.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4759A variants meeting identical 62 V/1 W specifications. Verify pinout compatibility and thermal resistance parameters when swapping brands. Ensure replacement parts maintain the same ±5% tolerance and impedance characteristics to preserve circuit performance integrity.
