BZX84C4V3S-7

Overview

The BZX84C4V3S-7 is a dual independent Zener diode array manufactured by Diodes Incorporated in the SOT-363 surface-mount package. It features a nominal Zener voltage of 4.3 V with a tolerance range of 4.0 V to 4.6 V at a test current of 5.0 mA. The device dissipates up to 200 mW and exhibits a maximum Zener impedance of 90 Ω at IZT and 600 Ω at IZK. Reverse leakage current is limited to 3.0 µA at 1.0 V, while forward voltage reaches 0.9 V at 10 mA. Operating temperature spans -65°C to +150°C.

Feature Summary

• Ultra-small SOT-363 surface mount footprint
• Lead-free and RoHS compliant manufacturing

Applications

• Voltage reference circuits
• Transient voltage suppression
• Clamping applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The datasheet indicates that the -7-F suffix corresponds to tape and reel quantities of 3000 units. Ensure the requested part number matches the required mechanical and electrical specifications before procurement.

Selection Notes

Select this component when a dual independent Zener configuration is required in a compact SOT-363 package. Verify that the 4.3 V nominal voltage and 200 mW power dissipation align with circuit requirements. Consider the ±6% tolerance and impedance characteristics for precision regulation needs.

Part Context

This component belongs to the BZX84C series of dual Zener diodes from Diodes Incorporated. The series offers various voltage options ranging from 2.4 V to 39 V within the same SOT-363 package. The 'S' designation identifies the dual independent configuration distinct from single or common cathode variants.

Replacement Considerations

Compatible substitutes include other dual Zener arrays in SOT-363 packages with matching 4.3 V ratings and 200 mW dissipation. Verify pinout compatibility and electrical parameters such as impedance and leakage current before substitution.
