Overview
The 1N5347B-AP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 5 W and utilizes a DO-15 axial leaded package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 7.6 V, a forward voltage of 1.2 V at 1 A, and a Zener impedance of 2 Ohms. The component operates within a temperature range of -55°C to +150°C.
Feature Summary
- Provides stable voltage regulation using silicon-oxide passivated junction technology.
- Engineered for high surge current handling capabilities in axial packages.
- Designed for reliable operation across extended industrial temperature ranges.
Applications
- Voltage reference circuits
- Overvoltage protection systems
- Power supply regulation
Procurement Notes
Verify the specific suffix AP against official MCC documentation to confirm packaging details and compliance status. Ensure the DO-15 package dimensions match your PCB layout requirements. Cross-reference the 10 V Zener voltage and 5 W power rating with your circuit design specifications before procurement.
Selection Notes
Select this component when a 5 W axial Zener diode with 10 V regulation is required. The DO-15 package supports through-hole mounting. Verify that the ±5% voltage tolerance meets your circuit precision needs. Confirm thermal management strategies are adequate for 5 W dissipation in the target application environment.
Part Context
This part belongs to the standard 1N53xx series of 5 Watt Zener diodes. These components are widely used in general-purpose electronics for voltage clamping and regulation. The 1N5347B designation specifically indicates a 10 V breakdown voltage variant within this high-power axial family.
Replacement Considerations
Compatible substitutes include the 1N5347B from ON Semiconductor and the 1N5347BE3/TR8 from Microsemi. Verify pinout compatibility and ensure equivalent power ratings and voltage tolerances before substitution.
