BZX84C3V0S-7-F

Overview

The BZX84C3V0S-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It utilizes planar die construction within an SOT-363 package, providing two isolated Zener junctions with a total power dissipation of 200 mW. The nominal Zener voltage is 3.0 V, operating within a range of 2.8 V to 3.2 V at a test current of 5.0 mA. Electrical characteristics include a maximum Zener impedance of 95 Ω and a maximum reverse leakage current of 10 µA at 1.0 V. The device operates across a temperature range of -65 °C to +150 °C.

Feature Summary

• Dual configuration offering two independent Zener diodes in a single ultra-small SOT-363 package
• Planar die construction designed for automated assembly processes
• Lead-free plating with matte tin finish annealed over Alloy 42 leadframe

Applications

• General regulation functions
• High-frequency applications
• Voltage reference circuits

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the standard 3000-unit tape and reel packaging format. Confirm that the component meets RoHS compliance standards and utilizes green molding compound if manufactured with date codes UO or newer. Ensure the procurement documentation aligns with the manufacturer's specifications for the SOT-363 case outline dimensions.

Selection Notes

Select this component when space-constrained designs require dual voltage regulation capabilities. The SOT-363 package provides a compact footprint suitable for high-density PCB layouts. Consider the 200 mW total power dissipation limit and the thermal resistance of 625 °C/W when designing heat management strategies for the application environment.

Part Context

This part belongs to the BZX84C2V4S through BZX84C39S series of dual Zener diodes. The series covers a wide working voltage range from 2.4 V to 39 V. All variants share identical mechanical data, including the SOT-363 plastic case and UL 94V-0 flammability rating, differing primarily in their electrical Zener voltage parameters and marking codes.

Replacement Considerations

Direct substitutes within the same family include other BZX84CxxS-7-F variants with different voltage ratings. Cross-manufacturer equivalents may exist but require verification of pinout compatibility and electrical parameter alignment against the official datasheet specifications.
