BZX84C4V3TS-7-F

Overview

The BZX84C4V3TS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated diode elements within an SOT-363 package. The nominal Zener voltage is 4.3 V, with a range of 4.0 V to 4.6 V at a test current (IZT) of 5 mA. Maximum reverse leakage current is 3.0 µA at VR = 1.0 V. Dynamic impedance is 90 Ω at IZT and 600 Ω at IZK = 0.5 mA. Power dissipation is 200 mW, operating temperature ranges from -65°C to +150°C, and thermal resistance is 625 °C/W.

Feature Summary

• Integrates three independent Zener diodes in a single ultra-small surface mount package
• Utilizes planar die construction for reliable performance
• Compliant with RoHS standards and lead-free plating specifications

Applications

• Voltage reference circuits requiring multiple stable potentials
• Over-voltage protection for low-voltage signal lines
• Clamping applications in compact electronic assemblies

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging type and compliance status. Ensure the component matches the required electrical characteristics for the intended circuit design before procurement.

Selection Notes

Select this component when space-constrained designs require multiple voltage references or clamping functions. Verify that the total power dissipation across all three channels remains within the 200 mW limit under maximum ambient temperature conditions.

Part Context

This part belongs to the BZX84C...TS series of triple Zener arrays. It shares the SOT-363 footprint with other variants in the family, offering different nominal voltages ranging from 2.4 V to 39 V while maintaining identical mechanical dimensions and pin configurations.

Replacement Considerations

Direct substitutes include other BZX84C4V3TS variants from Diodes Incorporated. Cross-manufacturer equivalents must match the SOT-363 package, 4.3 V nominal voltage, and 200 mW power rating.
