1N4752CE3/TR13

Overview

The Microchip Technology 1N4752CE3/TR13 is a silicon 1.0-watt Zener diode in the 1N4728A through 1N4764A series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 33 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• 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 reference circuits requiring precise regulation
• Power supply overvoltage protection
• General-purpose voltage clamping applications

Procurement Notes

Verify that the specific part number matches the required voltage tolerance and power dissipation ratings for your design. Confirm the presence of the 'e3' suffix indicates RoHS compliance and the 'TR13' suffix denotes tape and reel packaging. Ensure compatibility with your assembly process regarding lead form and moisture sensitivity classification level 1.

Selection Notes

Select this component when a 33 V regulation point with high precision is needed in an axial package. The ±2% tolerance offers tighter control than standard 5% variants. Consider the 1.0 W power rating and thermal resistance characteristics for heat management in your enclosure design compared to surface mount alternatives.

Part Context

This device belongs to the widely used 1N47xx series of silicon Zener diodes manufactured by Microsemi (now Microchip). The series covers voltages from 3.3 V to 100 V. The 'P' suffix denotes the plastic DO-41 package, while 'e3' confirms environmental compliance. This specific variant combines the popular 33 V rating with the tighter 'C' tolerance specification.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4752A or 1N4752B diodes in DO-41 packages. For equivalent performance with tighter tolerances, verify 1N4752C equivalents. Surface mount replacements such as SMAJ4752A are available if board space permits a package change.
