1N4755G R0G

Overview

The 1N4755G R0G is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in DO-204AL (DO-41) packages. It features a nominal Zener voltage of 43 V with a power dissipation rating of 1 W and a tolerance of ±5%. Key electrical parameters include a maximum reverse leakage current of 5 μA at 32.7 V and a maximum Zener impedance of 70 Ω. The device operates within a temperature range of -65°C to +200°C and is tested at a current of 6 mA.

Feature Summary

• Provides stable voltage regulation at a nominal 43 V output level
• Capable of handling 1 W power dissipation for robust circuit protection
• Engineered for high-temperature operation up to 200°C

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the specific manufacturer datasheet for the 1N4755G R0G to confirm exact electrical tolerances and thermal characteristics before integration. Ensure the DO-204AL package dimensions align with the target PCB layout. Confirm RoHS compliance status directly with the supplier or official documentation, as regulatory requirements may vary by production batch and region.

Selection Notes

Select this component when a 43 V Zener reference is required with 1 W power handling capabilities. The DO-204AL through-hole package suits applications where automated surface-mount assembly is not feasible. Consider the 70 Ω impedance limit for noise-sensitive designs and verify that the 5 μA leakage current meets the specific circuit's isolation requirements.

Part Context

This part belongs to the standard Zener diode category used for voltage clamping and regulation. The 'R0G' suffix typically indicates tape and reel packaging from Taiwan Semiconductor. It serves as a discrete semiconductor solution for maintaining stable potential differences in power supplies and signal conditioning circuits.

Replacement Considerations

The 1N4755A is a functionally equivalent Zener diode with identical 43 V and 1 W specifications. Verify pinout compatibility and package dimensions (DO-41) when substituting between manufacturers to ensure mechanical fit.
