1N4753A R1G

Overview

The 1N4753A R1G is a single silicon planar Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 36 V with a tolerance of ±5%. The device is designed for through-hole mounting in a DO-41 axial leaded package. It supports a maximum power dissipation of 1 W and operates within a temperature range of -55 °C to +150 °C junction temperature. Key electrical characteristics include a test current of 7 mA, a maximum reverse leakage current of 5 µA at 27.4 V, and a dynamic impedance of 50 Ω.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Provides precise voltage reference with ±5% tolerance
• Features low reverse leakage current for efficiency
• Supports high thermal stability up to 150 °C

Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix R1G against official Taiwan Semiconductor documentation to confirm packaging details and compliance status. Ensure the ordering quantity aligns with manufacturer minimum order requirements. Confirm RoHS and REACH compliance directly with the supplier or datasheet before procurement.

Selection Notes

Select this component when a 36 V Zener voltage with 5% precision is required in a through-hole configuration. Consider the 1 W power rating and 50 Ω dynamic impedance for circuit design. Verify that the DO-41 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes, widely used for general-purpose voltage regulation. The R1G suffix typically denotes a specific tape-and-reel packaging format, distinguishing it from bulk or ammo pack variants within the same electrical specification family.

Replacement Considerations

Equivalent parts include 1N4753A from other manufacturers such as Microchip Technology or Panjit International Inc., provided they meet the 36 V, 1 W, and DO-41 package specifications.
