1N4754APE3/TR8

Overview

The Microchip Technology 1N4754APE3/TR8 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 39 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a maximum power dissipation of 1.0 watts at 25°C. Electrical characteristics include a test current of 6.5 mA, a maximum dynamic impedance of 60 Ohms, and a maximum reverse current of 5 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Procurement Notes

Verify that the ordering suffix TR8 corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status via the e3 suffix designation and ensure the component meets environmental regulations applicable to the target market. Cross-reference the manufacturer part number with official datasheets to validate electrical parameters before integration into production designs.

Selection Notes

Select this component when a 39 V regulation point with 5% tolerance is required in a 1-watt power class. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Ensure the application current stays within the specified test current limits to maintain accuracy. Consider the operating temperature range and derating curves if ambient temperatures exceed standard conditions.

Part Context

This device belongs to the JEDEC registered 1N4728A through 1N4764A series of 1-watt Zener diodes. The 'P' suffix indicates plastic encapsulation, while the 'e3' suffix denotes RoHS compliance with annealed matte-tin plating. The 'TR' suffix identifies the tape and reel packaging option, facilitating high-volume surface mount or through-hole placement.

Replacement Considerations

Compatible substitutes include other 1N4754 variants from different manufacturers offering identical 39 V, 1 W specifications in DO-41 packages. Verify pinout compatibility and thermal resistance values when substituting.
