1N4752 G

Overview

The Microsemi Corporation 1N4752 G is a silicon Zener diode designed for voltage regulation applications. It features a hermetically sealed glass body construction within the DO-41 (DO-204AL) axial leaded package. The device provides a nominal Zener voltage of 33 V with a tolerance of 5%. It supports a maximum power dissipation of 1 W and operates reliably across an extended temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 45 Ω at a test current of 7.5 mA.

Feature Summary

• Hermetically sealed glass encapsulation ensures environmental protection and reliability
• Provides stable voltage regulation over a broad operating current and temperature range
• Features corrosion-resistant external surfaces and solderable pure tin-plated terminals

Applications

• Voltage reference circuits requiring high stability
• Overvoltage protection in sensitive electronic systems
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify that the specific part number includes the 'G' suffix, which denotes the hermetically sealed glass variant distinct from plastic or standard commercial versions. Confirm RoHS compliance status as it varies by manufacturing batch and suffix configuration. Ensure the supplier provides traceability documentation consistent with Microsemi's quality standards for hermetic devices.

Selection Notes

Select this component when hermetic sealing is required for harsh environments or high-reliability applications. The DO-41 package offers through-hole mounting compatibility. Compare thermal resistance requirements against plastic equivalents if higher heat dissipation is needed without hermetic constraints. Verify voltage tolerance needs against the standard 5% specification.

Part Context

This device belongs to the JEDEC registered 1N4728A through 1N4764A series of 1-watt Zener diodes. The 'G' suffix specifically identifies the glass-body option, offering superior temperature ratings and hermetic sealing compared to the plastic-bodied 'P' suffix variants within the same voltage lineup.

Replacement Considerations

Equivalent parts include the 1N4752AG and MV1N4752CGE3. Verify package compatibility and hermetic sealing requirements before substitution.
