IRF7313PBF

FET, MOSFET Arrays Overview

The IRF7313PBF is a dual N-channel HEXFET power MOSFET manufactured by Infineon Technologies, housed in an SO-8 surface-mount package. It features a maximum drain-source voltage (V_DS) of 30 V and a continuous drain current (I_D) of 6.5 A at 25°C. The device exhibits a maximum on-resistance (R_DS(on)) of 46 mΩ at 4.5 V gate drive and 29 mΩ at 10 V gate drive. Key electrical characteristics include a typical total gate charge (Q_G) of 22 nC at 10 V and a thermal resistance from junction to ambient (R_thJA) of 62.5 K/W. The component supports a maximum junction temperature of 150°C and operates within a temperature range of -55°C to 150°C.

FET, MOSFET Arrays Procurement Notes

Verify the specific ordering suffix PBF to confirm lead-free compliance and tube packaging format. Ensure the part number matches the exact dual N-channel specification rather than mixed polarity variants like the IRF7317 or IRF7319 series. Cross-reference with official Infineon documentation to confirm current production status and availability constraints.

FET, MOSFET Arrays Selection Notes

Select this component when a dual N-channel topology is required within an SO-8 footprint. Evaluate the 46 mΩ R_DS(on) at 4.5 V if driving directly from lower voltage logic sources. Consider the 62.5 K/W thermal resistance for PCB layout planning to ensure adequate heat dissipation under load conditions.

FET, MOSFET Arrays Part Context

This device belongs to the Infineon HEXFET family, known for optimized power performance in surface-mount packages. The IRF7313 variant specifically targets applications needing two matched N-channel switches, distinguishing it from single-channel counterparts like the IRF7413 or complementary pairs found in other series.

FET, MOSFET Arrays Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative dual N-channel MOSFETs based on pinout, voltage ratings, and thermal characteristics before substitution.
