Product details

Overview

IRF7468TRPBF from Infineon Technologies (acquired International Rectifier) is a 40 V, 9.4 A N-channel Trench MOSFET in SO-8 package, optimized for synchronous rectification in high-frequency isolated DC-DC converters and buck regulators. It delivers 15.5 mΩ R_DS(on) at V_GS = 10 V and 17.0 mΩ at 4.5 V, with ultra-low gate charge (Q_g = 23 nC typ.) and fast switching (t_r = 2.3 ns, t_f = 3.8 ns), enabling high-efficiency power conversion in telecom and CPU VRM applications.

For engineers reviewing the IRF7468TRPBF datasheet, IRF7468TRPBF pinout, IRF7468TRPBF application, or IRF7468TRPBF equivalent, key selection criteria include its 4.5 V logic-level gate drive compatibility, fully characterized avalanche rating (E_AS = 160 mJ), body diode reverse recovery performance (Q_rr = 76–110 nC), and thermal resistance (R_θJA = 50 °C/W).

Technical Context

This MOSFET employs Trench-based HEXFET architecture to achieve low conduction loss and enhanced switching speed. Its gate threshold voltage (V_GS(th) = 0.8–2.0 V) ensures reliable turn-on with standard logic-level drivers, while the 12 V maximum gate-source voltage supports robust overdrive margin without risk of oxide damage.

The device integrates a co-packaged body diode with specified reverse recovery characteristics (t_rr = 45–87 ns, Q_rr = 76–160 nC) and forward voltage (V_SD = 0.81 V @ 8.0 A, 25°C), making it suitable for synchronous rectification where diode conduction and commutation losses must be tightly controlled.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si7852DP-T1-GE3	R_DS(on) = 14.5 mΩ @ 10 V, Q_g = 28 nC, SO-8, 40 V	Higher gate charge increases driver loss; tighter R_DS(on) tolerance benefits precision current sensing.	Prefer when gate drive strength exceeds 1 A and layout allows 5 ns longer switching times.
DMN3020LSD-13	R_DS(on) = 19.5 mΩ @ 4.5 V, Q_g = 18 nC, SO-8, 30 V	Lower voltage rating limits use to ≤24 V systems; lower Q_g improves MHz-class efficiency.	Select only for 24 V automotive infotainment rails where 30 V V_DS suffices and gate drive is current-limited.

Compared with Si7852DP-T1-GE3 and DMN3020LSD-13, IRF7468TRPBF offers the best balance of 4.5 V drive capability, 40 V rating, and avalanche ruggedness-critical for unregulated input stages and fault-prone industrial environments.

FAQ

What is the maximum continuous drain current at 70°C ambient?

The IRF7468TRPBF supports 7.5 A continuous drain current at T_A = 70°C with V_GS = 10 V, derated from 9.4 A at 25°C per its linear derating factor of 0.02 mW/°C. This assumes SO-8 mounting on a standard FR-4 PCB with 1-inch² copper pour per JEDEC test conditions.

Does this MOSFET have avalanche capability, and how is it rated?

Yes-IRF7468TRPBF is fully characterized for single-pulse avalanche with E_AS = 160 mJ at T_J = 25°C and I_AR = 8.0 A. Testing follows the unclamped inductive switching (UIS) method per Figure 14a–c in the datasheet, using L = 5.0 mH and RG = 25 Ω.

Can IRF7468TRPBF be used with 3.3 V gate drive?

No-its gate threshold voltage range is 0.8–2.0 V, but R_DS(on) rises sharply below 4.5 V: at V_GS = 3.0 V, R_DS(on) exceeds 35 mΩ (per datasheet page 6, Fig 13). Reliable enhancement requires ≥4.5 V drive; 3.3 V systems require level-shifting or a different logic-level MOSFET.

What is the thermal resistance from junction to ambient (R_θJA) under standard conditions?

R_θJA is 50 °C/W when mounted on a standard FR-4 PCB with 1-inch² copper area per JEDEC 51-7. With an exposed pad soldered to a 2-inch² internal ground plane, R_θJA improves to ~35 °C/W, enabling higher power density in compact designs.
