1N4736AE3/TR13

Overview

The 1N4736AE3/TR13 is a single-channel Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device operates in the DO-41 axial package and supports through-hole mounting. Key electrical parameters include a maximum power dissipation of 1 W, a reverse leakage current of 10 µA at 1 V, and a Zener impedance of 8 Ohms. It functions within a temperature range of -65°C to +150°C and complies with RoHS standards.

Feature Summary

• Provides stable voltage regulation with a 6.8 V nominal output.
• Encapsulated in a moisture-resistant plastic DO-41 axial package.
• Capable of handling 1 W power dissipation for robust performance.

Applications

• General-purpose voltage reference circuits
• Overvoltage protection in low-power systems
• Biasing networks for semiconductor devices

Procurement Notes

Verify the specific suffix 'e3' confirms lead-free composition and RoHS compliance as per manufacturer specifications. Confirm the '/TR13' designation indicates reel packaging suitable for automated assembly processes. Ensure the ±5% voltage tolerance aligns with circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a precise 6.8 V regulation point is required in an axial form factor. The DO-41 package offers standard through-hole compatibility for prototyping and legacy board designs. Consider the 1 W power rating to ensure adequate thermal headroom under continuous operating conditions.

Part Context

This part belongs to the 1N47xx series of silicon Zener diodes produced by Microchip Technology. The series provides a wide range of voltage options from 3.3 V to higher values, all housed in the standardized DO-41 plastic encapsulation. The e3 suffix denotes environmental compliance, distinguishing it from older non-compliant variants.

Replacement Considerations

Direct replacements must match the 6.8 V Zener voltage, 1 W power rating, and DO-41 axial package. Verify that substitute components maintain equivalent Zener impedance and leakage current characteristics to ensure circuit stability without redesign.
