1N4753CPE3/TR8

Overview

The Microchip Technology 1N4753CPE3/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 36 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, denoted by the 'e3' suffix. It is supplied in tape-and-reel packaging per EIA-296 standards, as specified by the 'TR8' suffix.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the nominal Zener voltage.
• 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.
• Includes RoHS-compliant annealed matte-tin plating for solderability.

Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage sources in electronic circuits
• Protection against voltage transients

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'P' indicates plastic construction, 'e3' confirms RoHS compliance, and 'TR8' specifies the tape-and-reel packaging format. Ensure the component meets the necessary moisture classification level and screening requirements for the intended application environment before procurement.

Selection Notes

Select this component when a 36 V reference with high precision is required. The ±2% tolerance offers tighter control than standard 5% or 10% variants. Consider the thermal resistance and power derating curves if operating near maximum ratings. Verify compatibility with existing PCB footprints for the DO-41 package.

Part Context

This part belongs to the widely used 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The specific 'C' suffix denotes a tighter 2% tolerance compared to the standard 'A' suffix (5%) or no suffix (10%). The 'e3' suffix indicates RoHS compliance, while 'TR8' designates the reel packaging format.

Replacement Considerations

Equivalent parts include other 36 V Zener diodes with ±2% tolerance in the DO-41 package. Cross-reference with manufacturers offering similar 1W axial Zener diodes. Ensure electrical characteristics such as dynamic impedance and reverse current meet the circuit requirements.
