1N4735CE3/TR13

Overview

The Microchip Technology 1N4735CE3/TR13 is a silicon Zener diode providing voltage regulation within the 1N4728AP through 1N4764AP series. It features a nominal Zener voltage of 6.2 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in a DO-41 (DO-204AL) axial lead package and dissipates up to 1.0 W at 25°C. Electrical characteristics include a maximum dynamic impedance of 2 Ω, a reverse current of 10 μA at 1 V, and a test current of 41 mA. It supports an operating temperature range from -65°C to +150°C.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance on nominal Zener voltage.
• Features flexible axial-lead mounting terminals for through-hole integration.
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.
• RoHS compliant devices are available with the 'e3' suffix indicating annealed matte-Tin plating.

Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose electronic circuit protection
• Reference voltage generation in analog circuits

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix confirms RoHS compliance and specific terminal plating. The 'TR' suffix indicates tape and reel packaging per EIA-296 standards. Confirm the 'C' suffix corresponds to the required ±2% voltage tolerance. Ensure the component meets the necessary thermal resistance and power dissipation requirements for the intended application environment.

Selection Notes

Select this component when a 6.2 V reference with high precision is required. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Verify compatibility with MIL-PRF-19500 screening levels if military-grade reliability is needed. Consider the axial lead format for PCB layouts requiring through-hole mounting. Check derating curves for operation above 25°C ambient temperatures.

Part Context

This part belongs to the JEDEC registered 1N4728A to 1N4764A series of 1.0 watt Zener diodes. The series provides extensive voltage selection from 3.3 to 100 volts. The 'P' suffix designates plastic construction, while the 'e3' suffix denotes RoHS compliance. Surface mount equivalents are available as SMAJ4728A to SMAJ4764A and MLL4728A to MLL4764A.

Replacement Considerations

Surface mount equivalents include SMAJ4735A and MLL4735A. For higher reliability requirements, consider parts with MQ, MX, MV, or MSP prefixes for JAN, JANTX, JANTXV, and JANS screening respectively.
