1N4735CP/TR8

Overview

The Microchip Technology 1N4735CP/TR8 is a silicon Zener diode with a nominal voltage of 6.2 V and a 2% tolerance, indicated by the 'C' suffix. It operates in a DO-41 (DO-204AL) plastic axial package and dissipates up to 1.0 W at 25°C. The device features a maximum dynamic impedance of 2 Ω at a test current of 41 mA and a maximum reverse leakage current of 10 µA. It is supplied in tape and reel packaging per EIA-296 standards.

Feature Summary

• Provides precise voltage regulation with tight 2% tolerance for sensitive circuit applications
• Features flexible axial-lead mounting terminals suitable for through-hole PCB assembly
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 flammability ratings

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in power supply lines
• Clamping applications in signal processing paths

Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the presence of the TR suffix indicates tape and reel packaging rather than bulk or other formats. Ensure the C suffix corresponds to the necessary 2% voltage tolerance for your design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 6.2 V Zener voltage with high precision is required. The 1W power rating supports moderate current loads. Consider the DO-41 package dimensions for board layout constraints. Verify thermal derating requirements if operating above ambient temperatures to ensure reliable performance within the specified junction temperature limits.

Part Context

This part belongs to the 1N4728AP through 1N4764AP series of 1-watt plastic Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers an extensive voltage selection from 3.3 V to 100 V. These devices are JEDEC registered and designed for general-purpose voltage regulation tasks in industrial and commercial electronics.

Replacement Considerations

Equivalent parts include 1N4735A (5% tolerance), 1N4735AG (glass body), and 1N4735DP (1% tolerance). Surface mount equivalents such as SMAJ4735A or MLL4735A may be used if footprint adaptation is permitted.
