1N4760APE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N4760APE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, manufactured by Microsemi. It provides voltage regulation with a nominal Zener voltage of 68 V and a standard tolerance of ±5%. The device features a plastic encapsulated body (DO-41/DO-204AL) with flexible axial-lead terminals. Electrical characteristics include a maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA and a maximum reverse current of 13 µA at 51.7 V. It operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status prior to procurement. Confirm RoHS compliance via the e3 suffix and ensure tape and reel packaging matches TR12 specifications. Validate that the supplier sources directly from authorized channels to guarantee traceability and adherence to JEDEC registration standards for this specific part number.

Single Zener Diodes Selection Notes

Select this component when a 68 V Zener voltage with 5% tolerance is required in a 1-watt power dissipation package. The plastic construction offers lower thermal resistance compared to glass-body options. Ensure the application environment supports the specified operating temperature range and that the axial lead form factor fits the board layout constraints.

Single Zener Diodes Part Context

This part belongs to the widely used 1N47xx series of Zener diodes, specifically the AP variant which denotes plastic encapsulation. The series covers voltages from 3.3 V to 100 V. The e3 suffix indicates RoHS compliance with annealed matte-tin plating, while the TR suffix designates tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4760A variants with matching electrical ratings. Verify that any replacement maintains the same DO-41 package dimensions and 1-watt power dissipation capability. Cross-reference dynamic impedance and reverse leakage current specifications to ensure circuit performance parity.
