1N4736A-T

Overview

The Diodes Incorporated 1N4736A-T is a surface-mountable 1.0W Zener diode in the DO-41 glass package, designed for voltage regulation applications. It features a nominal Zener voltage of 6.8V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and includes lead-free finish compliant with RoHS directives. Electrical characteristics include a maximum reverse leakage current of 10µA at 4.0V and a surge current rating of 660mA.

Feature Summary

• Provides stable voltage regulation using a 1.0W power dissipation capability in a compact glass DO-41 case.
• Features a lead-free finish that meets RoHS compliance standards for environmental safety.
• Offers high thermal stability with an operating junction temperature range extending up to +175°C.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the cathode band polarity indicator on the glass body. Ensure the ordering suffix matches the required packaging format, as the '-T' designation specifically indicates tape and reel shipping rather than bulk or ammo pack configurations.

Selection Notes

Select this component when a 6.8V regulation point is required with a 1.0W power handling capacity. Consider the DO-41 axial leaded form factor for through-hole mounting requirements. Evaluate the thermal resistance characteristics relative to ambient temperature derating curves to ensure safe operation under expected load conditions.

Part Context

This part belongs to the 1N4728A through 1N4761A series of 1.0W Zener diodes manufactured by Diodes Incorporated. The series covers a wide voltage range from 3.3V to 75V, sharing common mechanical and electrical construction standards. The specific model utilizes a glass encapsulation material known for robustness and low capacitance characteristics.

Replacement Considerations

Diodes Incorporated recommends using the DFLZxx series for new designs instead of this legacy product. Verify pinout compatibility and thermal performance if substituting with equivalent parts from other manufacturers offering similar DO-41 packages.
