Overview
The MCC 1N4745A-TP is a silicon planar Zener diode housed in a hermetic DO-41G glass package. It provides a nominal voltage of 16 V with a 5% tolerance and a maximum power dissipation of 1 W at 50°C ambient temperature. The device features a reverse leakage current of 5 µA at 12.2 V, a forward voltage drop of 1.2 V at 200 mA, and a dynamic impedance of 16 Ohms. It operates within a temperature range of -65°C to +200°C.
Feature Summary
- Hermetically sealed glass construction for environmental stability
- Silicon planar technology for consistent electrical performance
- High thermal resistance capability up to 200°C junction temperature
Applications
- Voltage regulation in DC power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement instrumentation
Procurement Notes
Verify the specific suffix against official Micro Commercial Components documentation to confirm tolerance and packaging variations. Ensure compliance with RoHS3 standards and lead-free finish requirements as specified in the datasheet. Confirm authorized distributor status to mitigate counterfeit risks associated with semiconductor procurement.
Selection Notes
Select this component when a stable 16 V reference is required in through-hole designs. The DO-41G package accommodates standard PCB mounting techniques. Evaluate derating curves for high-temperature environments exceeding 50°C to maintain the 1 W power rating safely.
Part Context
This part belongs to the 1N47xx series of 1 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V. The 'A' suffix indicates a tighter 5% voltage tolerance compared to the standard 10% tolerance found in non-suffixed variants.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4745A equivalents in the DO-41 package. Verify that replacement parts meet the same 16 V nominal voltage, 1 W power dissipation, and 5% tolerance specifications.
