Overview
The MCC 1N4756A-TP is a silicon planar Zener diode housed in a hermetic DO-41 glass package. It provides a nominal Zener voltage of 47 V with a 5% tolerance, tested at 5.5 mA. The device dissipates up to 1.0 W and exhibits a maximum reverse leakage current of 5 µA at 35.8 V. Its dynamic impedance is 80 Ohms at the test current. Operating temperatures range from -65°C to +200°C.
Feature Summary
- Hermetically sealed glass construction for environmental stability
- Silicon planar technology for reliable voltage regulation
- Axial leaded DO-41G package design
Applications
- DC power supply voltage regulation
- Overvoltage protection circuits
- Voltage reference applications
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the specific suffix matches the required packaging format before ordering.
Selection Notes
Select this component when a precise 47 V reference is required within a through-hole assembly. The 5% tolerance suits standard regulation tasks. Ensure thermal derating is applied above 100°C to maintain safe junction temperatures during continuous operation.
Part Context
This part belongs to the 1N4728 through 1N4761 series, covering voltages from 3.3 V to 75 V. All devices share identical mechanical dimensions and thermal characteristics, differing only in their specific breakdown voltage ratings.
Replacement Considerations
Cross-reference with other manufacturers' 1N4756A equivalents. Verify that substitute components match the 47 V nominal rating, 1 W power dissipation, and DO-41 package constraints.
FAQ
What does the 'A' suffix indicate regarding voltage tolerance?
The 'A' suffix specifies a 5% tolerance on the nominal Zener voltage.
How is the Zener impedance measured?
It is derived from the 60 Hz AC voltage resulting from an AC current equal to 10% of the DC Zener current superimposed on the test current.
