1N4736PE3/TR12

Overview

The Microchip Technology 1N4736PE3/TR12 is a silicon 1.0-watt Zener diode in a plastic DO-41 axial lead package. It provides voltage regulation with a nominal Zener voltage of 6.8 V and a standard tolerance of ±10%. The device operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 10 µA at the test voltage and a dynamic impedance of 3.5 Ω at a test current of 37 mA. It is RoHS compliant and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits
• Power supply protection
• Reference voltage generation

Procurement Notes

Verify that the ordering suffix TR12 corresponds to the specified tape and reel packaging configuration as defined by the manufacturer's documentation. Confirm RoHS compliance status and ensure the component meets the required JEDEC registration standards for the specific application environment before finalizing procurement.

Selection Notes

Select this component when a 6.8 V reference with ±10% tolerance is required in an axial lead package. Ensure the circuit design accommodates the 1.0 W power dissipation limit and the thermal resistance characteristics of the DO-41 plastic case. Verify compatibility with the intended operating temperature range of -65°C to +150°C.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers extensive voltage selection from 3.3 to 100 volts. The 'P' suffix indicates plastic encapsulation, while the 'e3' suffix denotes RoHS compliance. These devices are registered under JEDEC standards.

Replacement Considerations

Compatible replacements include other 1N4736 variants such as 1N4736A or 1N4736Pe3/TR8, provided they match the electrical specifications and package type. Verify that any substitute maintains the same voltage tolerance and power rating.
