BSC009NE2LS5IATMA1 - 25V 0.95mΩ 217A OptiMOS 5 N-MOSFET | Infineon
MPN: BSC009NE2LS5IATMA1 ✓ Hoạt độngBSC009NE2LS5IATMA1 Tóm tắt
An N-channel MOSFET is a voltage-controlled majority-carrier device in which a positive gate-source voltage inverts the surface of a P-type body region to form an N-type conduction channel between source and drain. Within the broader semiconductor taxonomy, MOSFETs belong to the discrete power-device family (alongside IGBTs and GaN HEMTs), serving as the fundamental switching element in modern switch-mode power supplies, motor drives, and battery-protection circuits. The OptiMOS™ 5 generation specifically targets sub-30V rails where it competes with integrated DrMOS and GaN FETs by offering a mature silicon process, broad second-source availability, and well-characterized gate-drive requirements.
Key electrical parameters include V_DS = 25V maximum, V_GS(th) = 1.0V to 2.0V typical (1.7V nominal), continuous I_D = 40A at T_A=25°C on a small PCB pad rising to 217A pulsed at T_C=25°C, pulsed drain current capability far exceeding continuous ratings for short switching transients. Power dissipation is rated 2.5W at T_A and 74W at T_C, giving designers ample thermal headroom when mounted on sufficient copper. Total gate charge Q_G is 23 nC typical at V_GS=0 to 4.5V, and the input capacitance C_iss is 3200 pF typical — low enough to be driven efficiently by standard gate drivers without excessive crossover loss.
Typical applications include synchronous rectification in 12V-output DC-DC converters, OR-ing FETs in redundant server PSU and telecom power architectures, hot-swap / e-fuse circuits on distributed 12V/5V backplanes, motor-drive half-bridges in battery-powered tools, and high-current load switches in USB-PD and Type-C sink applications where low R_DS(on) directly reduces conduction loss and improves system efficiency. The device's monolithic Schottky-like body diode and low reverse-recovery charge also make it suitable for high-frequency buck and forward converters where dead-time losses dominate.
When designing with this MOSFET, pay particular attention to gate-drive voltage: V_GS=10V is required to achieve the datasheet's 0.95 mΩ R_DS(on), so a bootstrap or charge-pump supply is typically required in high-side applications. Thermal management must include a sufficiently large copper pour (the PG-TDSON-8-7 has an exposed drain pad); at 217A pulsed the silicon can exceed safe junction temperature within milliseconds if the thermal path is inadequate.

12V Synchronous Rectification
Used as the low-side FET in 12V-output buck converters where its 0.95 mΩ R_DS(on) and 23 nC Q_G minimize conduction and switching loss at 300-500 kHz. Per the Infineon datasheet, the device's low FOM (R_DS(on)×Q_G) outperforms prior OptiMOS generations, making it a strong fit for server and telecom point-of-load regulators seeking >97% efficiency.

OR-ing FET for Redundant Power
Used as an OR-ing FET in N+1 redundant 12V server PSU and telecom shelf architectures. The BSC009NE2LS5IATMA1's 0.95 mΩ R_DS(on) yields only 1.7W dissipation at 43A load per rail, while the fast body diode enables hot-swap insertion without ringing. The PG-TDSON-8-7 footprint accepts a heatsink tab for additional thermal margin in dense backplane designs.

Hot-Swap / e-Fuse Switch
Used as the main switching element in 12V hot-swap controllers on storage and networking backplanes. Per the Infineon datasheet, the device's 217A pulsed rating handles inrush transients from large bulk capacitors, while the 0.95 mΩ R_DS(on) keeps steady-state loss under 1W per FET at typical 30A loads, simplifying thermal management on FR-4 boards.

Battery-Protection Load Switch
Employed as the main disconnect FET in 3-4S lithium battery packs and portable power tools. The BSC009NE2LS5IATMA1's 25V V_DS rating, 0.95 mΩ R_DS(on), and SuperSO8 5x6 footprint deliver low-loss load switching in a compact PCB area. The 1.7V V_GS(th) allows direct drive from a low-voltage battery-monitoring MCU without auxiliary charge-pump circuitry.

Ghi chú thiết kế
Estimated: at 100A continuous conduction with V_GS=10V, power dissipation is P=I²×R = 100²×0.95mΩ ≈ 9.5W at T_J=25°C and roughly 13W at T_J=125°C (R_DS(on) rises ~40% hot). The PG-TDSON-8-7 package has θ_JC ≈ 1.5°C/W on the exposed drain pad; on a 1-square-inch 2-oz copper pour θ_JA falls to ~35°C/W. At 9.5W on a 35°C/W board, junction rise is ~330°C — clearly insufficient, so heatsinking or wider copper (≥3 sq-in 4-layer) is required for continuous 100A operation. For ≤40A typical applications, a 1 sq-in 2-oz pour is adequate.
Per the Infineon PG-TDSON-8-7 land-pattern recommendation, route the high-current drain on the top layer directly into the exposed pad — never through vias, since via resistance and inductance dominate at 100A+ peaks. Use multiple thermal vias (≥9×0.3mm) under the pad to inner copper planes. Keep the gate loop (gate-driver → gate resistor → gate pin → source pin → driver return) under 5 nH to prevent dv/dt-induced ringing that can cause MOSFET shoot-through in half-bridge configurations.
Do not assume V_GS(th)=1.7V is sufficient to fully enhance the device — at V_GS=4.5V R_DS(on) is roughly 2× the V_GS=10V figure (per Infineon datasheet characterization curves). For synchronous-rectifier bootstrap supplies, the bootstrap voltage may sag below 8V at light load, increasing conduction loss by 30-50%; use a charge pump or external 10V bias when possible. Also note that the device's avalanche rating is for unclamped inductive switching only — for H-bridge motor-drive applications, add external TVS diodes to absorb repetitive avalanche energy.
