1N4736A-T50A

Overview

The onsemi 1N4736A-T50A is a silicon unidirectional voltage regulator diode designed for through-hole mounting in the DO-41 axial package. It provides a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device handles a maximum power dissipation of 1 W and features a low reverse leakage current of 10 µA at 4 V. Its knee impedance is specified at a maximum of 700 Ω, ensuring stable regulation characteristics across its operating temperature range of -65 °C to 200 °C.

Feature Summary

• Provides precise voltage regulation via a stable 6.8 V Zener reference point
• Engineered for high thermal endurance with an extended operating temperature range up to 200 °C
• Utilizes a robust DO-41 axial leaded package suitable for standard through-hole circuit board layouts

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• Clamping applications for signal or power lines

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 1N4736A-T50A with official onsemi documentation. Confirm that the received units match the specified DO-41 package and electrical parameters. Ensure compliance with relevant environmental standards such as RoHS and REACH before integration into final assemblies.

Selection Notes

Select this component when a 6.8 V regulation point is required within a 1 W power budget. The DO-41 form factor is appropriate for designs prioritizing mechanical stability over surface mount density. Consider the specific knee impedance and leakage current specifications to ensure compatibility with the target circuit's sensitivity requirements.

Part Context

This device belongs to the 1N47xx series of general-purpose Zener diodes manufactured by onsemi. These components are widely utilized in basic electronic circuits for voltage stabilization and protection. The T50A suffix typically denotes specific packaging or tape-and-reel configurations offered by the manufacturer for automated assembly processes.

Replacement Considerations

Direct substitutes include the generic 1N4736A from onsemi and the 1N4736A from Nexperia USA Inc., which share identical electrical ratings and package dimensions.
