Overview
The BZX84C4V7S-7-F is a dual surface-mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 package. It provides two independent Zener diodes with a nominal voltage of 4.7 V and a tolerance range of 4.4 V to 5.0 V at a test current of 5 mA. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 80 Ohms at 5 mA, a reverse leakage current of 3.0 µA at 2.0 V, and a forward voltage of 0.9 V at 10 mA.
Feature Summary
- Dual configuration providing two independent Zener diodes in a single ultra-small surface mount package
- Planar die construction designed for general regulation functions
- Lead-free and RoHS compliant manufacturing process
Applications
- General voltage regulation circuits
- Voltage reference applications
- Clamping and protection circuits
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity levels before integration into production assemblies.
Selection Notes
Select this component when a dual Zener configuration is required in a compact footprint. Ensure the circuit design accommodates the 200 mW power dissipation limit and verify that the 4.7 V breakdown voltage aligns with the target regulation requirements.
Part Context
This part belongs to the BZX84C series of low-power voltage regulator diodes. The series offers various breakdown voltages from 2.4 V to 39 V in the SOT-363 package, providing designers with standardized options for small-form-factor regulation needs.
Replacement Considerations
Check datasheets for alternative dual Zener diodes in the SOT-363 package. Verify pinout compatibility, voltage tolerance, and power dissipation ratings to ensure functional equivalence without redesigning the PCB layout.
