1N4754CPE3/TR12

Overview

The Microchip Technology 1N4754CPE3/TR12 is a silicon 1.0-watt Zener diode in a plastic DO-41 axial package. It provides voltage regulation with a nominal Zener voltage of 39 V and a tight tolerance of ±2%. The device operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 5 µA at 23 V and a dynamic impedance of 60 Ohms at a test current of 6.5 mA. It is supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the nominal Zener voltage.
• Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.
• Offers flexible axial-lead mounting terminals for standard through-hole applications.
• Includes RoHS compliant annealed matte-Tin plating solderable per MIL-STD-750.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while 'P' denotes the plastic DO-41 package. Confirm the 'TR12' suffix corresponds to the specific tape and reel packaging format required for automated assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a stable 39 V reference with high precision is required. The ±2% tolerance makes it suitable for applications demanding tighter voltage control than standard 5% or 10% variants. Ensure the circuit design accommodates the 1 W power dissipation rating and the specified thermal resistance characteristics for reliable operation.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of Silicon 1 Watt Zener Diodes manufactured by Microsemi (now Microchip Technology). The series covers a voltage selection from 3.3 to 100 volts. The 'C' suffix specifically identifies the 2% tolerance variant within this family, distinguishing it from the standard 'A' suffix (5%) or no-suffix (10%) options.

Replacement Considerations

Compatible substitutes include other 1N4754 variants with matching electrical parameters. Verify that any replacement maintains the 39 V Zener voltage, 1 W power rating, and ±2% tolerance. Ensure the alternative device supports the DO-41 axial package and meets the same thermal and environmental operating requirements.
