BZX84C18TS-7-F

Overview

The BZX84C18TS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated diode elements within a single SOT-363 package. The nominal Zener voltage is 18.0 V, with a tolerance range of 16.8 V to 19.1 V at a test current of 5 mA. Maximum Zener impedance is 45 Ω at IZT and 225 Ω at IZK. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C.

Feature Summary

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

Applications

• Voltage reference circuits requiring multiple stable potentials
• Over-voltage protection for sensitive 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 that the component matches the required electrical specifications for the intended circuit design before finalizing procurement orders.

Selection Notes

Select this component when space constraints require multiple voltage references or clamping functions in a single footprint. Consider the thermal resistance and power derating characteristics if operating near maximum temperature limits.

Part Context

This part belongs to the BZX84C series of triple Zener arrays from Diodes Incorporated. It shares the same SOT-363 package and general electrical architecture as other variants in the family, differing primarily in the specific Zener voltage ratings provided by each internal element.

Replacement Considerations

Direct replacements include other BZX84C18TS variants from Diodes Incorporated. Cross-manufacturer equivalents must be verified for pinout compatibility and identical electrical parameters.
