Overview
The Fairchild Semiconductor 1N4750A_NL is a single silicon Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 27 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +200 °C. Packaged in the DO-41 axial through-hole format, it exhibits a maximum reverse leakage current of 5 µA and a Zener impedance of 35 Ohms at a test current of 9.5 mA.
Feature Summary
- Glass passivated die construction ensures long-term stability and reliability under various operating conditions.
- Capable of high power dissipation up to 1 W, suitable for robust voltage regulation tasks.
- Low inductance design facilitates performance in high-frequency switching environments.
Applications
- Voltage regulation circuits
- Voltage reference sources
- Overvoltage protection
Procurement Notes
Verify the specific manufacturer origin when sourcing this part number, as the suffix may indicate distribution by onsemi or legacy Fairchild inventory. Confirm RoHS compliance status and REACH SVHC declarations against the latest datasheet revision before integration. Ensure the package type matches the required PCB footprint and that thermal management aligns with the 1 W dissipation rating.
Selection Notes
Select this component for designs requiring a stable 27 V reference point with moderate power handling capabilities. The wide operating temperature range makes it suitable for industrial applications. Consider the DO-41 package dimensions for board layout constraints and verify that the 35 Ohm impedance meets the dynamic regulation requirements of the target circuit.
Part Context
This component belongs to the 1N47xx series of glass-passivated Zener diodes, widely used for general-purpose voltage regulation. The 1N4750A variant specifically targets the 27 V market segment. The _NL suffix typically denotes specific packaging or manufacturing lot details associated with the distributor or original equipment manufacturer's internal coding systems.
Replacement Considerations
Equivalent parts include the Rectron 1N4750A-B and Taiwan Semiconductor 1N4750A A0G. Verify pinout compatibility and ensure that replacement devices meet the same 1 W power dissipation and 27 V nominal voltage specifications.
