1N4735CPE3/TR12

Overview

The Microchip Technology 1N4735CPE3/TR12 is a silicon 1.0-watt Zener diode 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 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 compliance, denoted by the 'e3' suffix. It is supplied in tape and reel packaging for automated assembly.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance on the 6.2 V breakdown voltage
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• RoHS compliant with annealed matte-Tin plating solderable per MIL-STD-750

Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against electrostatic discharge (ESD) as it is nonsensitive per MIL-STD-750 Method 1020
• General purpose clipping and clamping circuits in electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'C' indicates a 2% voltage tolerance, 'P' denotes the plastic DO-41 package, 'e3' confirms RoHS compliance, and 'TR12' specifies the tape and reel packaging format. Confirm manufacturer details align with Microsemi/Microchip Technology documentation before finalizing procurement orders.

Selection Notes

Select this component when a stable 6.2 V reference or regulator is required with tighter accuracy than standard 5% variants. The plastic construction offers lower thermal resistance compared to glass-body options. Ensure the application environment supports the specified operating temperature range and power dissipation limits at elevated temperatures.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes. The series provides extensive voltage selection from 3.3 to 100 volts. While standard 'A' suffix devices offer 5% tolerance, the 'C' suffix variant specifically addresses applications requiring higher precision voltage regulation without sacrificing the robust mechanical properties of the plastic encapsulation.

Replacement Considerations

Compatible substitutes include other 1N4735 variants with matching electrical characteristics. The 1N4735DP offers 1% tolerance in the same package, while the 1N4735AG provides 5% tolerance. Surface mount equivalents such as SMAJ4735A are available if board space constraints require a different form factor.
