Overview
The Microchip Technology 1N4759CP/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, manufactured by the Scottsdale Division. It provides voltage regulation with a nominal Zener voltage of 62V and a tight tolerance of +/- 2%, indicated by the 'C' suffix. The device features a plastic encapsulated DO-41 or DO-204AL package with axial leads. Electrical characteristics include a maximum dynamic impedance of 125 Ohms at a test current of 4.0 mA and a maximum reverse current of 5 µA at a test voltage of 47.1 V. It operates within a temperature range of -65°C to +150°C.
Feature Summary
- Provides precise voltage regulation with a standard 2% tolerance on nominal Zener voltage.
- Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability classification.
- Offers flexible axial-lead mounting terminals suitable for various installation requirements.
- Constructed with JEDEC registered design ensuring compatibility with standard electronic circuits.
Applications
- Voltage regulation in power supply circuits
- Reference voltage generation in analog systems
- Overvoltage protection for sensitive components
Procurement Notes
Verify that the ordering suffix matches the required specifications. The 'P' suffix indicates plastic construction, while 'e3' denotes RoHS compliance. Confirm the 'TR' suffix aligns with tape and reel packaging requirements per EIA-296 standards. Ensure the 'C' suffix is present for the specified 2% voltage tolerance. Cross-reference the manufacturer part number with official datasheets to confirm electrical parameters before procurement.
Selection Notes
Select this component when a 62V Zener voltage with high precision is required. The plastic package offers lower thermal resistance compared to glass-body options. Consider the 1.0-watt power dissipation rating and operating temperature range for thermal management. Verify that the axial lead configuration fits the board layout constraints. Check for surface mount equivalents if space is limited.
Part Context
This component belongs to the popular 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series provides a wide selection of voltages from 3.3 to 100 volts. The specific model utilizes a plastic encapsulation which is moisture classified as Level 1, eliminating the need for dry pack storage. It serves as a standard solution for general-purpose voltage regulation applications.
Replacement Considerations
Surface mount equivalents are available as SMAJ4759A and MLL4759A. Consult the factory for other compatible variants. Ensure replacement parts match the 62V nominal voltage and 2% tolerance requirement. Verify package dimensions and pinout compatibility for direct substitution.
