BZX84C3V0S-7

Overview

The BZX84C3V0S-7 is a dual independent surface mount Zener diode manufactured by Diodes Incorporated. It features planar die construction within an SOT-363 package, providing two isolated Zener elements with a nominal voltage of 3.0 V and a tolerance of ±5%. The device supports a maximum power dissipation of 200 mW at 25°C ambient temperature, with a thermal resistance of 625 °C/W. Electrical characteristics include a maximum Zener impedance of 95 Ω at a test current of 5 mA and a maximum reverse leakage current of 10 µA at 1 V. The component operates across a junction temperature range of -65°C to +150°C.

Feature Summary

• Dual independent Zener configuration in an ultra-small SOT-363 surface mount package
• Planar die construction for robust performance
• Lead-free plating with matte tin finish annealed over Alloy 42 leadframe

Applications

• General-purpose voltage regulation functions
• High-frequency applications due to low capacitance characteristics
• Voltage reference circuits requiring compact form factors

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging type and compliance status. The standard designation typically indicates tape and reel packaging. Confirm RoHS compliance and green material status based on the manufacturing date code, as older production runs may utilize different molding compounds. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The 3.0 V nominal voltage suits low-voltage reference or clamping needs. Verify that the 200 mW power dissipation rating aligns with the thermal design constraints of the target PCB layout. Consider the ±5% tolerance for precision requirements and ensure the operating temperature range meets environmental specifications.

Part Context

This part belongs to the BZX84C series of dual surface mount Zener diodes. The 'S' suffix denotes the SOT-363 case style, distinguishing it from single-element variants like the BZX84C W-series. The series covers a wide voltage range from 2.4 V to 39 V, offering standardized marking codes for inventory management and automated assembly processes.

Replacement Considerations

BZX84C3V0S-7-F is a parameter-equivalent alternative from Diodes Incorporated with identical electrical specifications and packaging.
