Overview
The MCC 1N5368B-TP is a single silicon Zener diode housed in the DO-15 axial through-hole package. It provides a nominal Zener voltage of 47 V with a ±5% tolerance and a maximum power dissipation of 5 W. Key electrical parameters include a test current of 25 mA, a maximum dynamic impedance of 25 Ohms, and a maximum reverse leakage current of 0.5 µA at 35.8 V. The device supports a maximum regulator current of 100 mA and can withstand a surge current of 2.7 A.
Feature Summary
- Epoxy body meets UL 94 V-0 flammability rating
- Lead-free finish compliant with RoHS standards
- High temperature solder exemption applied
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation
Procurement Notes
Verify that the ordering suffix -TP confirms lead-free and RoHS compliance as specified by the manufacturer. Confirm the package type matches the required DO-15 form factor for your assembly process. Ensure the requested quantity aligns with available packing options such as tape and reel or bulk packaging to match production line requirements.
Selection Notes
Select this component when a stable 47 V reference is required in high-power applications up to 5 W. Consider the 25 Ohm dynamic impedance for regulation precision needs. Verify that the operating junction temperature range of -55°C to +150°C under DC conditions fits the environmental constraints of the target design.
Part Context
This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers a wide voltage range from 5.1 V to 200 V within the same DO-15 package family. All devices share common thermal characteristics and mounting dimensions, facilitating standardized design practices across different voltage requirements.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material.
FAQ
What is the maximum operating junction temperature for DC conditions?
The maximum operating junction temperature for DC conditions is 150°C, though it may reach 200°C for pulsed conditions with low duty cycle.
How is the maximum regulator current determined?
The maximum regulator current is based on the maximum voltage of a 5% type unit and must not exceed the value of 5 watts divided by the actual Zener voltage.
