BZX84C16S-7-F

Overview

The BZX84C16S-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 package. It features a nominal Zener voltage of 16 V with a tolerance range of 15.3 V to 17.1 V at a test current of 5 mA. The device has a maximum power dissipation of 200 mW and a maximum reverse leakage current of 100 nA at 11.2 V. Electrical characteristics include a maximum Zener impedance of 40 Ω at the test current and 200 Ω at a lower current of 1 mA. The component operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual configuration providing two independent Zener diodes within a single ultra-small surface mount package.
• Planar die construction designed for automated assembly processes.
• Lead-free plating with matte tin finish annealed over an Alloy 42 leadframe.

Applications

• Voltage reference circuits requiring compact dual-channel solutions.
• Clamping applications for signal lines or power rails.
• Protection circuits against transient voltage spikes.

Procurement Notes

Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the date code aligns with material specifications if halogen-free status is critical for the application. Ensure the supplier provides documentation confirming compliance with RoHS directives and UL flammability ratings as specified in the datasheet.

Selection Notes

Select this component when space constraints require a dual Zener array in an SOT-363 footprint. Verify that the 16 V nominal voltage fits the circuit requirements and that the 200 mW power dissipation rating is sufficient for the expected operating conditions. Consider the thermal resistance of 625 °C/W when designing the PCB layout to ensure adequate heat dissipation.

Part Context

This part belongs to the BZX84C2V4S through BZX84C39S series of dual Zener diodes from Diodes Incorporated. The series offers various voltage options ranging from 2.4 V to 39 V, all sharing the same SOT-363 mechanical outline and general electrical characteristics structure. The marking code for this specific voltage is KY5.

Replacement Considerations

Direct replacements must match the SOT-363 package, 16 V nominal voltage, and dual configuration. Verify that alternative manufacturers provide equivalent Zener impedance and leakage current specifications to maintain circuit performance.
