1N4750PE3/TR12

Overview

The Microchip Technology 1N4750PE3/TR12 is a silicon 1.0-watt Zener diode in the JEDEC registered 1N4728A to 1N4764AP series. It provides voltage regulation at a nominal Zener voltage of 27V with a standard tolerance of plus or minus 5%. The device features a plastic encapsulated DO-41 (DO-204AL) axial-lead package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 35 Ohms at a test current of 9.5 mA, a maximum reverse current of 5 µA at a test voltage of 20.6 V, and a maximum forward voltage of 1.2 V at 200 mA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 27V reference
• Power supply protection and clamping applications
• General purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm compliance requirements and packaging options. Confirm that the 'e3' suffix indicates RoHS compliant annealed matte-Tin plating and the 'TR' suffix denotes tape and reel packaging. Ensure procurement specifications align with the manufacturer's latest datasheet revisions to avoid discrepancies in terminal plating or moisture classification levels.

Selection Notes

Select this component when a 27V Zener voltage with 5% tolerance is required for through-hole assembly. Consider the 1.0-watt power dissipation rating and thermal resistance characteristics for heat management. Verify compatibility with existing circuit designs regarding test currents and dynamic impedance values. Evaluate the plastic package construction for environmental protection and mechanical stability in the target application environment.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers an extensive voltage selection from 3.3 to 100 volts. These plastic encapsulated devices are designed for general-purpose voltage regulation and are available in various screening levels and packaging configurations to meet diverse industrial and commercial needs.

Replacement Considerations

Equivalent parts within the same JEDEC series may be considered if voltage and power ratings match. Verify that alternative suppliers offer compatible DO-41 packages and similar electrical parameters. Check for any differences in terminal plating or moisture sensitivity levels that might affect soldering processes.
