Overview
The BZX84C3V3S-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes housed in an SOT-363 package with a total power dissipation of 200 mW. The nominal Zener voltage is 3.3 V, with a tolerance range of 3.1 V to 3.5 V at a test current of 5 mA. Maximum reverse leakage current is 5 µA at 1 V, and maximum Zener impedance is 95 Ω at 5 mA and 600 Ω at 1 mA. The device operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Dual independent Zener diodes integrated into a single ultra-small surface mount package for high-density applications.
- Planar die construction designed for optimal automated board assembly processes.
- Lead-free and RoHS compliant manufacturing with UL 94V-0 flammability rating.
Applications
- Voltage regulation functions
- General purpose circuit protection
Procurement Notes
Verify the specific manufacturer part number against official datasheets before procurement. Confirm that the ordering suffix matches the required packaging format. Ensure compliance with environmental standards such as RoHS if applicable to the final assembly requirements.
Selection Notes
Select this component when space constraints require dual voltage references or clamping functions in a minimal footprint. Verify that the 200 mW power dissipation limit accommodates the thermal conditions of the target application. Check that the 3.3 V breakdown voltage aligns with the circuit design specifications.
Part Context
This component belongs to the BZX84C series of silicon planar Zener diodes produced by Diodes Incorporated. The series offers various breakdown voltages ranging from 2.4 V to 39 V. The 'S' designation indicates a dual configuration, while the '-7-F' suffix specifies the tape and reel packaging quantity.
Replacement Considerations
Direct substitutes include other dual Zener arrays in SOT-363 packages with matching electrical characteristics. Verify pinout compatibility and thermal resistance values when considering alternative manufacturers.
