1N4752G

Overview

The Taiwan Semiconductor 1N4752G is a single-die Zener diode housed in a DO-41 through-hole package. It provides a nominal Zener voltage of 33 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -65 °C to +200 °C. Electrical characteristics include a test current of 7.5 mA, a maximum regular impedance of 45 Ω at the test current, and a leakage current of 5 µA at 25.1 V reverse voltage.

Feature Summary

• Hermetically sealed glass construction for corrosion resistance
• Pure tin plated leads ensuring solderability per J-STD-002
• Wide selection of Zener voltages ranging from 3.3V to 56V

Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix (R0G for reel or A0G for ammo box) against project requirements. Confirm RoHS compliance status as indicated in the datasheet. Ensure the chosen variant meets the required packing quantity constraints for automated assembly lines. Cross-reference the marking code to verify authenticity upon receipt.

Selection Notes

Select this component when a robust, hermetically sealed Zener regulator is needed for general-purpose voltage reference tasks. The DO-41 package suits through-hole mounting environments. Consider the thermal resistance values if operating near the maximum power dissipation limit. Verify that the 33 V nominal output aligns precisely with circuit design specifications before finalizing the bill of materials.

Part Context

This part belongs to the 1N4728G–1N4758G series manufactured by Taiwan Semiconductor. The series covers a broad spectrum of Zener voltages from 3.3 V up to 56 V. All devices share identical mechanical dimensions and packaging standards, differing primarily in their electrical breakdown characteristics. This specific model represents the mid-range voltage option within the lineup.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4752 variants meeting the same JEDEC DO-41 outline and 33 V specification. Ensure replacement parts maintain the ±5% tolerance and 1 W power rating. Verify that alternative sources also offer hermetically sealed glass construction if environmental sealing is critical to the application.
