Overview
The Microsemi Corporation 1N4755 G is a Zener voltage regulator diode designed for through-hole mounting in a DO-35-2 glass axial leaded package. This component provides stable voltage regulation within the standard 1N47xx series specifications, utilizing silicon junction technology. It serves as a reliable discrete semiconductor solution for maintaining constant voltage levels across various electronic circuits.
Feature Summary
- Provides precise voltage regulation using Zener breakdown characteristics
- Features hermetic-sealed glass encapsulation for environmental protection
- Designed for robust through-hole installation on printed circuit boards
Applications
- Voltage reference circuits requiring stable DC potentials
- Overvoltage protection stages in power supply inputs
- General-purpose voltage regulation in analog signal conditioning
Procurement Notes
Verify the specific manufacturer designation and suffix requirements before ordering, as availability may vary between original Microsemi stock and current authorized distributors. Confirm RoHS compliance status and exact packaging quantities directly with the supplier to ensure alignment with project specifications and regulatory standards.
Selection Notes
Select this component when a standard 1W Zener diode in a compact glass DO-35 package is required. Ensure the operating voltage aligns with the specific series rating and that the thermal environment supports the device's maximum rated temperature limits without additional heat sinking measures.
Part Context
This part belongs to the widely recognized 1N47xx series of Zener diodes, a staple in discrete semiconductor design. The 'G' suffix typically denotes the glass body construction, distinguishing it from plastic encapsulated variants like the 'P' suffix models within the same electrical family offered by Microsemi.
Replacement Considerations
Compatible substitutes include the 1N4755A (plastic DO-41) or 1N4755DPE3TR (plastic DO-41). Verify that replacement packages match the physical footprint and that thermal resistance differences do not impact performance in the existing design.
