1N4735PE3/TR12

Overview

The Microchip Technology 1N4735PE3/TR12 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 6.2 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance indicated by the e3 suffix. Packaged in tape and reel format per EIA-296 standards, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 6.2 V 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 package type, lead finish, and packaging quantity. Ensure the component meets required environmental classifications and screening levels for the intended application before procurement.

Selection Notes

Select this component for applications requiring a 6.2 V Zener voltage with 5% tolerance in a 1-watt power dissipation rating. Consider the plastic DO-41 package for its lower thermal resistance compared to glass-body options and verify compatibility with automated assembly processes due to the tape and reel packaging.

Part Context

This part belongs to the widely used 1N47xxA series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a voltage range from 3.3 V to 100 V, offering various tolerance options and package styles including plastic and glass bodies. The 1N4735 variant specifically targets the 6.2 V regulation segment.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4735A or 1N4735AP devices in the DO-41 package. Verify electrical characteristics such as dynamic impedance and reverse leakage current match the original specifications.
