Product details
Overview
IRFHS8342TR2PBF from Infineon Technologies is a 30 V, 8.5 A N-channel enhancement-mode HEXFET Power MOSFET in a 2 mm × 2 mm PQFN package with 16 mΩ RDS(on) at VGS = 10 V, optimized for high-efficiency buck converter control and system/load switching in space-constrained DC-DC applications.
For engineers reviewing the IRFHS8342TR2PBF datasheet, IRFHS8342TR2PBF pinout, IRFHS8342TR2PBF application, or IRFHS8342TR2PBF equivalent, key selection criteria include low-profile thermal performance (RθJC(Bottom) = 13 °C/W), fast switching (tr = 15 ns, tf = 5.0 ns), and gate charge (Qg = 4.2 nC @ VGS = 4.5 V) for high-frequency synchronous rectification.
Technical Context
This MOSFET features a trench-gate HEXFET structure enabling low on-resistance and fast switching with integrated body diode (VSD = 1.0 V @ IS = 8.5 A). Its 2 mm × 2 mm PQFN package provides bottom-side thermal path and MSL1 industrial qualification.
Gate threshold voltage is tightly specified (1.35–2.35 V), supporting 3.3 V and 4.5 V logic-level drive. Reverse recovery parameters (Qrr = 13–20 nC, trr = 11–17 ns) are characterized for synchronous buck operation with controlled di/dt = 330 A/μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - supports 24 V input rail with 25 % margin for transient spikes |
| RDS(on) max @ VGS = 10 V | 16.0 mΩ - enables ≤1.15 W conduction loss at 8.5 A continuous current |
| Qg typ @ VGS = 4.5 V | 4.2 nC - reduces gate driver power demand in 1–2 MHz switching converters |
| RθJC(Bottom) | 13 °C/W - allows direct PCB copper thermal coupling for >2 W dissipation without heatsink |
| ID @ TC(Bottom) = 25 °C | 8.5 A - defines maximum steady-state current under bottom-side heatsinking |
| tr/tf | 15 ns / 5.0 ns - minimizes switching transition losses in high-frequency PWM stages |
| VGS(th) | 1.35–2.35 V - ensures reliable turn-on with standard 3.3 V microcontroller GPIO |
Pinout & Package
IRFHS8342TR2PBF uses a 6-pin PQFN (2 mm × 2 mm, 1.0 mm height) with exposed drain pad for thermal conduction. Pin 1–6 are assigned as Drain, Source, Gate, Drain, Source, Drain respectively in top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Drain | Main high-side current path; connected to PCB thermal pad for heat extraction |
| 2 (S) | Source | Power return node; referenced for gate drive and current sensing |
| 3 (G) | Gate | Control terminal requiring <10 Ω series resistance to damp ringing |
| 4 (D) | Drain | Parallel drain connection to reduce package inductance and improve current sharing |
| 5 (S) | Source | Secondary source tie for reduced source loop inductance in synchronous rectifiers |
| 6 (D) | Drain | Third drain connection enhancing thermal and electrical parallelism |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 16 mΩ max at 10 V drive enables <1.2 W conduction loss at full rated current |
| Low-profile PQFN | 1.0 mm height supports ultra-thin power modules and portable electronics |
| Bottom-side thermal path | RθJC(Bottom) = 13 °C/W enables direct PCB copper cooling without thermal vias |
| Logic-level gate drive | VGS(th) range (1.35–2.35 V) ensures compatibility with 3.3 V and 4.5 V controllers |
| MSL1 industrial rating | Guarantees moisture sensitivity robustness for reflow assembly in high-reliability production |

FAQ
What is the maximum continuous drain current at 70°C ambient temperature?
The IRFHS8342TR2PBF supports 7.1 A continuous drain current at TA = 70°C with VGS = 10 V, derated from its 8.5 A rating at 25°C ambient due to thermal limits in standard PCB mounting conditions.
Does this MOSFET require a gate resistor for stability?
Yes - a 5–10 Ω series gate resistor is recommended to damp high-frequency oscillation caused by gate-drain capacitance (Crss = 46 pF) and PCB layout inductance, especially in hard-switched buck topologies operating above 500 kHz.
Can IRFHS8342TR2PBF be used in synchronous rectification?
Yes - its low RDS(on) (16 mΩ), fast body diode (trr = 11–17 ns), and low Qrr (13–20 nC) make it suitable for low-voltage synchronous rectifier roles in secondary-side DC-DC stages, particularly where 3.3 V or 4.5 V gate drive is available.
Is the PQFN package lead-free and RoHS compliant?
Yes - the IRFHS8342TR2PBF carries "PbF" in its part number and is fully RoHS compliant, containing no lead, bromide, or halogen, and qualified to MSL1 per J-STD-020 for industrial surface-mount reflow processes.
