1N4759E3/TR13

Overview

The Microchip Technology 1N4759E3/TR13 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP 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) 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 at 5 V, and a maximum surge current of 2000 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard circuit integration
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement instrumentation

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while 'TR13' denotes tape and reel packaging. Confirm the specific voltage tolerance and package type requirements against the datasheet before finalizing procurement orders to ensure compatibility with design constraints.

Selection Notes

Select this component when a 62 V Zener voltage with ±5% tolerance is required for 1-watt applications. Consider the plastic DO-41 package for lower thermal resistance compared to glass-body options. Ensure the application environment stays within the specified -65°C to +150°C operating temperature range and accounts for the necessary derating curves for steady-state power dissipation.

Part Context

This part belongs to the JEDEC registered 1N4728A to 1N4764A series manufactured by Microsemi (now Microchip Technology). The series offers an extensive voltage selection from 3.3 to 100 volts. The 1N4759 variant specifically targets the higher end of this voltage spectrum, providing regulation capabilities suitable for various industrial and commercial electronic designs requiring reliable voltage clamping.

Replacement Considerations

Surface mount equivalents such as SMAJ4759A or MLL4759A are available. Verify pinout compatibility and thermal management requirements when transitioning between axial-lead and surface-mount packages.
