1N4736CPE3/TR12

Overview

The Microchip Technology 1N4736CPE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 axial lead package. It provides voltage regulation with a nominal Zener voltage of 6.8 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 via the 'e3' suffix. Packaged in tape and reel format as specified by the 'TR12' suffix, it offers flexible mounting terminals and low thermal resistance compared to glass-body options.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance for stable reference applications
• Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Offers flexible axial-lead mounting terminals suitable for various PCB configurations
• Includes RoHS compliant annealed matte-Tin plating solderable per MIL-STD-750

Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose voltage reference circuits requiring tight tolerance
• Protection against voltage spikes in electronic systems

Procurement Notes

Verify that the specific ordering suffix matches the required tolerance and packaging configuration. Confirm the manufacturer designation aligns with current corporate structures following industry acquisitions. Ensure the component meets all necessary environmental compliance standards for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this component when a 6.8 V reference with ±2% accuracy is required in an axial lead package. Consider the 1.0 W power dissipation rating and the specific thermal resistance characteristics for heat management. Verify compatibility with existing circuit designs regarding test current requirements and dynamic impedance specifications.

Part Context

This part belongs to the JEDEC registered 1N4728A to 1N4764A series of 1.0 watt Zener diodes. The series provides a wide selection of voltages from 3.3 to 100 volts. The plastic encapsulated version offers lower thermal resistance compared to glass-body options while maintaining identical electrical characteristics to the standard registration.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4736A variants with matching 6.8 V and ±2% tolerance ratings. Surface mount equivalents such as MLL4736A are available for density-constrained designs. Verify that any substitute maintains the same power dissipation and temperature operating limits.
