1N4736CP/TR8

Overview

The Microchip Technology 1N4736CP/TR8 is a silicon 1.0-watt Zener diode in the 1N4728AP to 1N4764AP series, housed in a plastic DO-41 (DO-204AL) 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 a maximum dynamic impedance of 3.5 Ohms at a test current of 37 mA. It includes a tape and reel option for automated assembly.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance on nominal Zener 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.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B, requiring no dry pack.

Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose voltage reference functions
• Over-voltage protection circuits

Procurement Notes

Verify that the ordering suffix 'TR8' corresponds to the specific tape and reel packaging configuration required for your manufacturing line. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch or region. Ensure the component meets all relevant military screening levels if applicable to your design specifications.

Selection Notes

Select this component when a 6.8 V reference with tighter than standard tolerance is required. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Verify that the 1.0 W power dissipation rating aligns with your circuit's thermal management capabilities and derating requirements at elevated ambient temperatures.

Part Context

This part belongs to the JEDEC registered 1N4728A through 1N4764A series of 1.0 watt Zener diodes. The 'P' suffix denotes plastic construction, while the 'C' suffix specifies the ±2% voltage tolerance. The 'e3' suffix indicates RoHS compliance, and 'TR' signifies the tape and reel packaging format.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4736A variants with matching 6.8 V ratings and ±2% tolerances. Surface mount equivalents such as MLL4736A are available for high-density designs. Ensure replacement components maintain the same DO-41 package dimensions and thermal characteristics.
