1N4759CPE3/TR12

Overview

The Microchip Technology 1N4759CPE3/TR12 is a silicon 1.0-watt Zener diode in a plastic DO-41 axial package. It provides voltage regulation at a nominal Zener voltage of 62 volts with a tight tolerance of plus or minus 2 percent. The device operates within a temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating. Electrical characteristics include a maximum dynamic impedance of 125 ohms at a test current of 4.0 mA, a maximum reverse current of 5 microamperes, and a maximum regulator current of 14 mA.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance for sensitive circuit applications
• Utilizes void-free transfer molded thermosetting epoxy body for durability
• Offers flexible axial-lead mounting terminals for standard through-hole integration
• Ensures reliability with nonsensitive ESD performance per MIL-STD-750 Method 1020

Applications

• Voltage reference circuits requiring stable 62V regulation
• Overvoltage protection stages in power supply designs
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific C suffix indicates the required 2% voltage tolerance against project specifications. Confirm the TR12 designation aligns with tape and reel handling requirements. Ensure compliance with RoHS directives by checking the e3 suffix documentation. Validate that the plastic construction meets thermal resistance limits for the intended operating environment.

Selection Notes

Select this component when a 62-volt regulation point is necessary with tighter accuracy than standard 5% variants. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Consider the 1-watt power dissipation capability and axial lead form factor for board layout constraints. Verify compatibility with existing manufacturing processes for reel-based assembly.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a voltage range from 3.3 to 100 volts in JEDEC registered formats. The P suffix denotes plastic construction, while the C suffix specifies the 2% voltage tolerance level.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4759C equivalents meeting identical electrical parameters. Cross-reference with 1N4759A for 5% tolerance if precision is not critical. Surface mount alternatives such as SMAJ4759A are available for space-constrained designs.
