1N4760CP/TR12

Overview

The Microchip Technology 1N4760CP/TR12 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation at a nominal 68 V with a tight 2% tolerance, indicated by the 'C' suffix. 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 150 ohms at a test current of 3.7 mA and a maximum reverse current of 5 µA at 51.7 V. The component is supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance on nominal Zener voltage
• Features a void-free transfer molded thermosetting epoxy body for moisture resistance
• Offers flexible axial-lead mounting terminals compatible with standard PCB layouts
• Maintains stable operation across a broad operating current and temperature range

Applications

• Voltage reference circuits requiring high precision
• Power supply regulation and protection
• Overvoltage clamping in electronic systems

Procurement Notes

Verify that the specific part number matches the required tolerance and packaging configuration. Confirm RoHS compliance status if applicable to your manufacturing standards. Ensure the supplier provides valid traceability documentation for the microelectronic components. Check for any specific handling requirements related to the tape and reel format during assembly.

Selection Notes

Select this component when a 68 V regulation point with strict 2% accuracy is required. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Consider the 1-watt power dissipation capability and the specific test current conditions when designing the biasing network. Verify that the operating environment stays within the specified temperature limits.

Part Context

This device belongs to the JEDEC registered 1N4728A to 1N4764A series of 1-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix denotes plastic construction, while the 'TR' suffix indicates tape and reel packaging. The 'C' suffix specifically identifies the tighter 2% voltage tolerance variant within this family.

Replacement Considerations

Equivalent parts include other 1N4760 variants with matching 68 V ratings and 2% tolerances. Plastic package alternatives such as 1N4760AP or 1N4760AP,e3 are functionally similar. Ensure replacement devices meet the same thermal and electrical specifications for direct substitution.
