1N4754CE3/TR13

Overview

The Microchip Technology 1N4754CE3/TR13 is a silicon 1-watt Zener diode designed for voltage regulation. It features a nominal Zener voltage of 39V with a tight tolerance of +/- 2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes a plastic DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 60 Ohms at a test current of 6.5 mA, a maximum reverse current of 5 µA, and a steady-state power dissipation of 1.0 watt.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance on nominal Zener voltage
• Features flexible axial-lead mounting terminals in a void-free transfer molded epoxy body
• Operates reliably over a broad temperature range from -65°C to +150°C
• Compliant with RoHS standards through annealed matte-Tin plating

Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against transient overvoltage events in electronic systems
• Power supply output stabilization and clipping applications

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix confirms RoHS compliance and indicates the use of lead-free terminations. The 'TR13' designation specifies tape and reel packaging. Ensure the component meets the specific voltage tolerance requirements defined by the 'C' suffix before procurement.

Selection Notes

Select this component when a 39V Zener voltage with high precision is required. The plastic construction offers lower thermal resistance compared to glass-body options. Consider the 1-watt power dissipation capability and the operating temperature range to ensure compatibility with the target application's thermal environment and electrical load.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of 1-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series provides a wide selection of voltages from 3.3V to 100V. The 'P' suffix denotes plastic encapsulation, while the 'e3' suffix indicates environmental compliance. These devices are JEDEC registered and suitable for general-purpose voltage regulation tasks.

Replacement Considerations

Equivalent parts within the same series include 1N4754A, 1N4754AP, and 1N4754Pe3. Verify that substitute components match the 39V nominal voltage, 2% tolerance, and 1-watt power rating. Ensure the replacement package type and terminal configuration are compatible with the existing PCB layout.
