1N4759P/TR12

Overview

The Microchip Technology 1N4759P/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, providing voltage regulation with a nominal Zener voltage of 62 V and a standard tolerance of ±5%. It operates within a temperature range of -65°C to +150°C and features a plastic DO-41 (DO-204AL) axial-lead package. The device has a maximum reverse current of 5 µA at a test voltage of 47.1 V, a dynamic impedance of 125 Ω at a test current of 4.0 mA, and a maximum regulator current of 14 mA.

Feature Summary

• Plastic encapsulated construction offering lower thermal resistance compared to glass-body options.
• JEDEC registered part number ensuring standardized electrical characteristics.
• Moisture classification Level 1 requiring no dry pack storage.
• ESD nonsensitive per MIL-STD-750 Method 1020.

Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage sources in electronic circuits
• Surge protection applications

Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the 'e3' suffix indicates RoHS compliance if lead-free terminals are necessary. Ensure the 'TR' suffix corresponds to tape and reel packaging requirements. Check for any prefix identifiers if military screening levels such as JAN or JANTX are needed. Validate the manufacturer designation against current corporate records.

Selection Notes

Select this component when a 62 V Zener voltage with 5% tolerance is required in a 1 W power dissipation class. Choose the plastic package variant for improved thermal performance relative to glass equivalents. Consider the axial-lead format for through-hole mounting configurations. Evaluate the operating temperature limits against the specific environmental conditions of the target application.

Part Context

This component belongs to the 1N4728AP through 1N4764AP series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix designates the plastic molded case, while the 'e3' suffix denotes RoHS compliant devices available from the manufacturer.

Replacement Considerations

Surface mount equivalents are available as SMAJ4759A and MLL4759A. Other manufacturers may offer direct replacements within the 1N4759A JEDEC specification family.
