SP6150-01HTG

Overview

The Littelfuse SP6150-01HTG is a Surface Mount Device (SMD) ESD protection diode array and EMI filter integrated into an SOT23-3 package. It provides electrostatic discharge protection rated at ±30kV for contact and air discharge methods per IEC 61000-4-2 standards. The component incorporates a C-R-C network to attenuate electromagnetic interference, achieving greater than -25dB attenuation at 400MHz with a filtering frequency range from 400MHz to 3GHz. It operates within a temperature range of -40°C to 125°C and features a capacitance of 100pF.

Feature Summary

• Integrates EMI filtering capabilities directly with ESD protection in a compact surface mount package
• Provides high-level electrostatic discharge immunity meeting stringent IEC 61000-4-2 contact and air discharge requirements
• Offers significant signal attenuation in the radio frequency spectrum to reduce electromagnetic interference

Applications

• General purpose electronic circuit protection
• High-speed data line shielding against static discharge
• RF signal path interference suppression

Procurement Notes

Verify the specific suffix HTG corresponds to the required tape and reel packaging configuration when ordering. Confirm that the SOT23-3 footprint matches the target PCB design constraints. Ensure the operating voltage rating aligns with the system's maximum signal levels to prevent device failure during normal operation.

Selection Notes

Select this component when space-constrained designs require combined ESD and EMI mitigation. The SOT23-3 form factor suits applications where board real estate is limited. Consider the 100pF capacitance value to ensure compatibility with high-speed signal integrity requirements without excessive signal degradation.

Part Context

This part belongs to the Littelfuse SP6150 series, which focuses on general-purpose protection solutions. The series integrates passive filtering elements with transient voltage suppression diodes. This integration simplifies bill of materials by replacing separate discrete components for noise filtering and static protection.

Replacement Considerations

Consult official Littelfuse documentation for verified cross-reference part numbers. Do not substitute based solely on package similarity; verify electrical parameters such as breakdown voltage and clamping characteristics.
