SNZF220DFT1G

Overview

The SNZF220DFT1G is a dual EMI/RFI bidirectional Pi-type low-pass filter with integrated electrostatic discharge (ESD) protection, manufactured by onsemi. It features a diode capacitance of 7–10 pF and a Zener/resistor array line capacitance of 22 ±20% pF. The device includes a Zener breakdown voltage ranging from 6 to 8 V and a maximum leakage current of 1 μA for the Zener diode. Designed for surface-mount applications in the SC-88 package, it meets IEC61000-4-2 standards for ESD protection and holds AEC-Q101 automotive certification with PPAP capability.

Feature Summary

• Dual EMI/RFI bidirectional Pi-type low-pass filter design effectively suppresses electromagnetic and radio frequency interference.
• Provides reliable electrostatic discharge protection compliant with IEC61000-4-2 standards.
• Automotive-grade reliability certified under AEC-Q101 with production part approval program (PPAP) capability.

Applications

• Electromagnetic interference suppression in systems requiring noise filtering
• Electrostatic discharge protection for sensitive electronic components
• Automotive electronics applications requiring high reliability

Procurement Notes

Verify that the specific order matches the SNZF220DFT1G designation to ensure inclusion of AEC-Q101 automotive certification and PPAP compliance. Confirm the SC-88 surface-mount package type aligns with board layout requirements. Ensure the supplier provides documentation confirming the component meets IEC61000-4-2 ESD protection standards as specified in the official datasheet.

Selection Notes

Select this component when a combined solution for EMI/RFI filtering and ESD protection is required in a compact form factor. The bidirectional Pi-filter topology offers effective noise suppression while the integrated Zener diodes provide voltage clamping. Consider the SC-88 package size for space-constrained designs and verify compatibility with automotive quality standards if used in vehicle systems.

Part Context

This component belongs to onsemi's family of EMI filters and ESD protection devices designed for robust signal integrity management. It integrates passive filtering elements with active protection diodes to address multiple interference sources simultaneously. The device serves as a specialized solution for protecting data lines and power inputs in environments prone to electrical noise and static discharge events.
