Overview
The BZX84C4V7S-7-F is a dual independent Zener diode array manufactured by Diodes Incorporated. It features a nominal Zener voltage of 4.7 V with a tolerance range of 4.4 V to 5.0 V, tested at a current of 5 mA. The device operates within an ambient temperature range of -65°C to +150°C and dissipates up to 200 mW of power. Key electrical parameters include a maximum Zener impedance (ZZT) of 80 Ohms and a maximum reverse leakage current of 3.0 µA at 2.0 V. The component utilizes a compact SOT-363 surface-mount package.
Feature Summary
- Dual independent Zener configuration in a single ultra-small SOT-363 package
- Planar die construction for robust performance
- Lead-free and RoHS compliant manufacturing
Applications
- Voltage regulation circuits requiring dual reference levels
- Clamping applications for signal protection
- Biasing networks in low-power electronic devices
Procurement Notes
Verify the specific ordering suffix when sourcing components. The base type number BZX84C4V7S requires the addition of the -7-F suffix for standard tape and reel packaging containing 3000 units per reel. Confirm that the requested part matches this complete designation to ensure correct packaging and availability from authorized distributors.
Selection Notes
Select this component for designs requiring two independent 4.7 V references in a minimal footprint. Ensure the circuit design accounts for the 200 mW total power dissipation limit and the thermal resistance characteristics. Verify that the required Zener impedance and leakage current specifications align with the application's precision requirements.
Part Context
This device belongs to the BZX84C series of dual Zener diodes produced by Diodes Incorporated. The series offers various breakdown voltages ranging from 2.4 V to 39 V, all housed in the same SOT-363 case. This specific variant provides the 4.7 V option within the C-tolerance family.
Replacement Considerations
Direct replacements must match the SOT-363 package, 200 mW power rating, and 4.7 V dual Zener configuration. Other manufacturers offering equivalent dual Zener arrays in SOT-363 packages may be considered if their electrical parameters meet or exceed the specified limits.
