BZX84C20TS-7-F

Overview

The BZX84C20TS-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 20.0 V, with a tolerance range of 18.8 V to 21.2 V at a test current of 5 mA. Maximum Zener impedance is 55 Ω at the test current and 225 Ω at a low current of 1 mA. The device supports a maximum power dissipation of 200 mW and operates across a temperature range of -65°C to +150°C. Reverse leakage current is limited to 0.1 µA at 14.0 V.

Feature Summary

• Integrates three electrically isolated Zener diodes in one ultra-small surface mount package
• Utilizes planar die construction for reliable voltage regulation
• Compliant with RoHS standards and lead-free manufacturing requirements

Applications

• Voltage reference circuits requiring multiple independent rails
• Over-voltage protection for sensitive signal lines
• Clamping applications in compact portable electronics

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before purchase. Confirm that the date code aligns with project timelines, as manufacturing processes may vary based on production year. Ensure compatibility with standard reflow soldering profiles specified for the SOT-363 case material.

Selection Notes

Select this component when space constraints necessitate multiple voltage references in a minimal footprint. Compare the 20V nominal rating against circuit requirements to ensure proper breakdown characteristics. Consider the thermal resistance of 625 °C/W when designing PCB layouts to manage heat dissipation effectively under load.

Part Context

This part belongs to the BZX84C series of triple Zener arrays from Diodes Incorporated. The series covers a wide voltage range from 2.4V to 39V, allowing designers to choose specific breakdown voltages while maintaining consistent packaging and electrical characteristics across the family.

Replacement Considerations

Direct substitutes include other BZX84C20TS variants from Diodes Incorporated. Cross-manufacturer equivalents in the SOT-363 package should be verified for matching pinout orientation and electrical tolerances.
