TPD3F303DPVR

Overview

The TPD3F303DPVR is a highly integrated three-channel ESD protection and EMI filter designed for SIM card interfaces. It features an RC(Pi) low-pass topology with second-order filtering characteristics. The device operates within a voltage range of up to 5.5 V and provides ±15 kV ESD protection per IEC standards. Electrical parameters include channel resistances of 47 ohms and 100 ohms, with a capacitance of 20 pF. The -3 dB cutoff frequency is specified at 294 MHz and 308 MHz. It is housed in an 8-pin USON (DPV) package measuring 2.10 mm by 1.60 mm with a height of 0.65 mm.

Feature Summary

• Integrates three-channel ESD protection with an internal VCC clamp circuit for SIM card interface applications
• Provides second-order low-pass RC(Pi) EMI filtering to suppress electromagnetic interference
• Offers robust transient protection rated at ±15 kV contact discharge and ±30 kV air discharge

Applications

• SIM card interface circuits
• Mobile device data lines
• Portable electronic equipment requiring ESD and EMI suppression

Procurement Notes

Verify the specific suffix DPVR corresponds to the required tape-and-reel packaging configuration. Confirm that the 8-UFDFN bare pad package dimensions align with the target PCB footprint. Ensure the operating temperature range of -40°C to 85°C meets the environmental requirements of the final assembly. Cross-reference the RoHS3 compliance status with current regulatory mandates for the destination market.

Selection Notes

Select this component when simultaneous ESD protection and EMI filtering are required for high-speed digital lines such as SIM interfaces. The integrated VCC clamp simplifies design by eliminating external clamping diodes. Consider the 47/100 ohm resistance values for impedance matching requirements. The compact USON package is suitable for space-constrained mobile designs where board real estate is limited.

Part Context

This part belongs to the Texas Instruments TPD series of ESD protection devices. It is specifically engineered for protecting sensitive input/output ports against electrostatic discharge events while maintaining signal integrity through integrated filtering. The device complements other TI protection solutions by combining transient suppression with passive filtering in a single surface-mount package.
