BZX84C11S-7

Overview

The BZX84C11S-7-F is a dual surface-mount Zener diode array manufactured by Diodes Incorporated in the SOT-363 package. It provides two independent Zener diodes with a nominal voltage of 11 V, ranging from 10.4 V to 11.6 V at a test current of 5 mA. The device features a maximum power dissipation of 200 mW and operates within a temperature range of -65 °C to +150 °C. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 8 V and a maximum dynamic impedance of 20 Ω at 5 mA.

Feature Summary

• Dual configuration containing two independent Zener diodes within a single ultra-small surface mount package.
• Planar die construction designed for optimal automated board assembly and high-density applications.
• Lead-free and RoHS compliant manufacturing utilizing matte tin finish plating over an Alloy 42 leadframe.

Applications

• Voltage reference circuits requiring compact dual-channel regulation.
• Clamping and protection stages for sensitive input/output lines.
• Biasing networks in portable electronic devices where space is limited.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The standard designation typically indicates tape and reel quantities of 3000 units. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity level ratings before finalizing procurement specifications.

Selection Notes

Select this component when a dual Zener configuration is required in a minimal footprint. Ensure the application voltage does not exceed the 11 V nominal rating and that the total power dissipation remains within the 200 mW limit. Consider the thermal resistance of 625 °C/W when designing heat dissipation strategies for dense PCB layouts.

Part Context

This part belongs to the BZX84C series of dual Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.4 V to 39 V, all housed in the standardized SOT-363 case. This specific model represents the 11 V variant within that lineup, sharing identical mechanical and electrical structural parameters with other voltages in the family.

Replacement Considerations

Direct replacements must match the SOT-363 package and dual independent configuration. Verify that substitute parts maintain equivalent Zener voltage tolerances and power dissipation limits. Cross-reference manufacturer datasheets to ensure pinout compatibility and thermal performance alignment.
