1N4735UR-1/TR

Overview

The Microchip Technology 1N4735UR-1/TR is a surface mountable 1.0 W glass Zener diode in the DO-213AB package. It provides a nominal Zener voltage of 6.2 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 10 µA at 3 V. Electrical characteristics include a test current of 41 mA, a dynamic impedance of 2 Ohms at IZT, and a maximum regulator current of 146 mA.

Feature Summary

• Hermetically sealed glass MELF package for high reliability applications
• Surface mount design suitable for high density mounting
• Inherently radiation hard per MicroNote 050
• ESD nonsensitive construction

Applications

• Voltage regulation in high density circuits
• High reliability applications requiring source control drawings
• Low parasitic requirement environments

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel configuration. Confirm RoHS compliance status if applicable. Ensure the manufacturer designation aligns with current corporate structures following acquisitions. Cross-reference datasheet revisions to confirm electrical parameters match design requirements.

Selection Notes

Select this component when a 1.0 W surface mount Zener diode is required. The DO-213AB package offers a leadless alternative to axial leads. Consider the ±5% voltage tolerance as standard. Evaluate thermal derating curves for steady-state power dissipation limits based on ambient temperature conditions.

Part Context

This part belongs to the 1N4728UR through 1N4764AUR series of surface mount glass Zener diodes. These devices are electrically equivalent to the JEDEC registered 1N4728A through 1N4764A series but utilize the DO-213AB outline. The series covers Zener voltages from 3.3 V to 100 V.

Replacement Considerations

Equivalent axial leaded parts include 1N4735A. Surface mount equivalents include MLL4735A.
