What are the key features of IRF7341TRPBF?
- Dual N-channel MOSFET in a single SO-8 package, with each channel rated at 55V and 4.7A
- Ultra-low 50mΩ (0.05Ω) drain-source on-resistance minimizing conduction losses in switching circuits
- Avalanche-rated construction with 140mJ avalanche energy rating for robust overvoltage protection
- High reliability design suitable for demanding industrial and automotive load-switching applications
- Separate gate/source connections for each channel enabling independent control of two MOSFET switches
- Integrated body diodes per channel allowing synchronous rectification and freewheeling in motor drives
What is IRF7341TRPBF used for?
The IRF7341TRPBF is designed for dual-channel load switching, synchronous DC-DC converters, and H-bridge motor drive circuits where two independent N-channel MOSFETs are required in a minimal board area. Its ultra-low 0.05Ω on-resistance and 4.7A per channel rating enable efficient power conversion with low I²R losses in notebook power management, portable device chargers, and brushed DC motor controllers. The avalanche energy rating of 140mJ makes this MOSFET reliable in designs exposed to inductive kickback and voltage transients.

Frequently Asked Questions
What is the maximum drain-source on-resistance of IRF7341TRPBF and how does it impact power efficiency?
The IRF7341TRPBF has a maximum Rds(on) of 0.05Ω (50mΩ), which produces only 0.235W of conduction loss per channel at full 4.7A current rating. This ultra-low on-resistance makes it highly efficient for synchronous rectification and load-switch applications, and at typical 1A to 2A currents in portable device power paths, the conduction loss drops to as little as 50mW to 200mW per channel, contributing minimal heat in thermally constrained designs.
How does the 140mJ avalanche energy rating of IRF7341TRPBF protect circuits from inductive load transients?
The IRF7341TRPBF's 140mJ avalanche energy rating means each MOSFET channel can absorb up to 140mJ of energy from unclamped inductive loads during turn-off transients before risking device failure. This is critical in motor drive and relay switching applications where coil inductance can spike drain-source voltage beyond the 55V breakdown threshold. The avalanche capability provides a built-in safety margin when the external clamp diode or snubber circuit is insufficient to fully suppress the voltage spike.
When should an engineer use IRF7341TRPBF's dual MOSFET configuration versus two discrete single N-channel devices?
The IRF7341TRPBF integrates 2 independent N-channel MOSFET channels in a single SO-8 package, saving PCB area equivalent to two separate SOT-23 or SO-8 devices while simplifying the BOM. This dual configuration is ideal for bidirectional load switches, complementary switch pairs in synchronous buck converters, and H-bridge half-bridge stages where both switches share the same rated parameters of 55V and 4.7A. The main trade-off is shared thermal resistance, which requires verifying that total power dissipation from both channels does not exceed the package's 2.5W typical SO-8 thermal limit.
What gate drive voltage is recommended for the IRF7341TRPBF to achieve its minimum 50mΩ on-resistance specification?
The IRF7341TRPBF achieves its specified maximum 0.05Ω (50mΩ) on-resistance when driven with a gate-source voltage (Vgs) of 10V, making it optimally suited for 10V to 12V gate drive circuits common in industrial motor controllers and DC-DC converters. At lower gate voltages such as 4.5V (logic-level drive), the on-resistance will increase above 50mΩ, and full compatibility with 3.3V microcontroller GPIOs requires a gate driver IC to boost the drive signal to ensure consistent switching performance across temperature.
