1N4744A B0G

Overview

The 1N4744A B0G is a silicon planar power Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 15 V with a tolerance of 5%. The device is housed in a DO-41 glass axial leaded package, suitable for through-hole mounting. It has a maximum steady-state power dissipation of 1 W at temperatures up to 50°C, with derating required above this threshold. The component operates within a temperature range of -65°C to +200°C and exhibits a maximum reverse leakage current of 5 µA.

Feature Summary

• Hermetically sealed glass compression bonded construction
• Corrosion resistant external surfaces
• Readily solderable pure tin plated leads

Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage sources

Procurement Notes

Verify the specific suffix 'B0G' against official Taiwan Semiconductor documentation to confirm exact packaging or marking variations. Ensure compliance with RoHS directives if required by the application. Confirm availability directly with the manufacturer or authorized distributors as standard stock levels may vary.

Selection Notes

Select this component for applications requiring a 15 V reference in a robust DO-41 package. Consider the 1 W power rating and thermal derating characteristics for circuit design. Verify that the hermetically sealed construction meets environmental requirements compared to non-sealed equivalents.

Part Context

This part belongs to the 1N47xx series of 1 Watt Zener Voltage Regulators. These devices are widely used in general-purpose electronics for voltage stabilization. The DO-41 package provides a reliable mechanical form factor for automated assembly and manual soldering processes.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4744A variants in DO-41 packages. Ensure electrical parameters such as Zener voltage tolerance and power dissipation match the original design specifications.
