1N4752A R1G

Overview

The Taiwan Semiconductor 1N4752A R1G is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device operates in the DO-41 axial through-hole package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 45 Ω at a test current of 7.5 mA, and an operating temperature range from -65 °C to +200 °C.

Feature Summary

• Hermetically sealed glass compression bonded construction
• Corrosion resistant external surfaces
• Terminals readily solderable per MIL-STD-208

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify the specific suffix 'R1G' against the official Taiwan Semiconductor datasheet to confirm packaging details and availability status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a stable 33 V reference is required in high-temperature environments due to its extended operating range. The DO-41 package facilitates easy integration into through-hole PCB layouts. Consider the 45 Ω impedance value for dynamic load regulation performance in sensitive analog circuits.

Part Context

This part belongs to the standard 1N47xx series of one-watt Zener diodes manufactured by Taiwan Semiconductor. These devices are widely used in industrial electronics for basic voltage clamping and regulation tasks. The 1N4752A designation specifically identifies the 33 V variant within this extensive product family.

Replacement Considerations

Compatible substitutes include the 1N4752A from other manufacturers such as Micro Commercial Components or Continental Device India Limited, provided they meet the same 33 V, 1 W, and DO-41 specifications.
