BSC036NE7NS3GATMA1 - 75V 100A N-Channel OptiMOS 3 MOSFET | Infineon
MPN: BSC036NE7NS3GATMA1 ✓ Hoạt độngBSC036NE7NS3GATMA1 Tóm tắt
An N-channel MOSFET is a voltage-controlled semiconductor switch in which applying a positive gate-source voltage above the threshold (typically 1-3 V) creates an inversion-layer conduction channel between drain and source. Within the broader component taxonomy, a power MOSFET belongs to the discrete semiconductor > transistor > MOSFET family, used as the primary switching element in power conversion stages such as synchronous buck converters, motor drives, and hot-swap controllers. Infineon's OptiMOS 3 technology targets high-frequency, high-current density applications where low conduction and switching losses are critical.
Key features include a low on-state resistance of 3.6 mOhm max at 10 V VGS, fast switching for high-frequency converters up to 1 MHz, an integrated gate-source protection Zener (ESD protection), and an exposed pad (EP) for direct PCB thermal coupling. The PG-TDSON-8-7 outline keeps the source current path symmetrical and minimizes package parasitic inductance, enabling clean switching edges in multi-MHz power stages.
The 31 C/W junction-to-case thermal resistance supports high continuous current loading, while the small 5x6 mm footprint allows 30 A/inch^2 power stage density. OptiMOS 3 also reduces gate charge (Qg typ ~ 45 nC) which directly lowers switching losses in hard-switched topologies. For server and telecom 48 V input stages, automotive 24 V buck converters, and high-current load switches, this part provides an industry-standard figure of merit (FOM = Rds(on) x Qg).
Typical applications include synchronous rectification in 48 V server / telecom intermediate bus converters, solar inverter power stages, motor drive half-bridges, hot-swap and OR-ing controllers, and battery management protection MOSFETs for 12 V/24 V/48 V systems. The wide 75 V VDS rating provides adequate derating margin below the standard 48 V bus.
Design trade-off to remember: at high VIN the low Rds(on) is partially offset by switching losses; drive the gate with a 4.5-10 V driver to stay in full enhancement. Below 4.5 V VGS the device moves into the linear region, dissipating large power at high current.

48V Telecom/Server Synchronous Buck Converter
The BSC036NE7NS3GATMA1's 3.6 mOhm RDS(on) and 75 V VDS rating make it ideal as the synchronous (low-side) FET in 48 V-to-PoL buck converter stages for telecom and hyperscale servers. At 30 A continuous load, conduction loss is only 3.2 W per switch, keeping multi-phase 48 V designs thermally manageable. With Qg of 45 nC, the device supports 500 kHz to 1 MHz switching, enabling high power density in small 1U server form factors. Place it on the same PG-TDSON-8-7 footprint as the high-side control FET (e.g. BSC100N10NSFGATMA1) to minimize the power loop and switching overshoot. The exposed pad must be soldered to a copper pour of at least 100 mm^2 for proper thermal dissipation.

Ghi chú thiết kế
At 50 A continuous drain current and 3.6 mOhm RDS(on), conduction loss is P = I^2 * R = 50^2 * 0.0036 = 9 W. With RthJC = 0.8 C/W, junction temperature rises 9 * 0.8 = 7.2 C above case temperature. The PG-TDSON-8-7 exposed pad must be soldered to at least 100 mm^2 of copper pour (top + bottom layer stitching with thermal vias) to achieve the rated 156 W power dissipation. For continuous high-current operation above 30 A, attach a heatsink or fan-cooled cold plate. Estimated: junction rise is for steady-state conduction loss only; switching loss at 500 kHz adds approximately 1-2 W per FET.
Route the high-current drain and source traces on top and bottom layers with minimum 10 mm width (for 50 A with 1 oz copper) to minimize conduction loss. Use a tight switching loop with the gate drive return (source connection) less than 5 mm long to minimize parasitic inductance and ringing. Stitch the exposed thermal pad with an array of 0.3 mm thermal vias on 1.0 mm pitch down to an inner copper plane for heat spreading. Keep high dv/dt switching nodes away from sensitive analog feedback traces to avoid capacitive coupling. Place input bulk capacitors within 5 mm of the FET source terminal.
The PG-TDSON-8-7 source pins (2, 3, 8) are internally connected to the exposed pad. Use all source pins and the exposed pad together for maximum current handling and thermal performance. Do not split source connections between the gate driver ground (Kelvin connection) and the power return - use a small gate-drive pull-down resistor at the gate IC output to keep high di/dt current out of the gate driver ground path. Avoid long gate traces - gate resistance above 5 ohm will slow switching and increase switching loss. Estimated: each 10 mm of gate trace adds approximately 1 nH of parasitic inductance.
Common pitfalls: (1) Driving the gate below 4.5 V VGS pushes the FET into the linear region, causing severe dissipation; always verify VGS at full load with worst-case driver output. (2) Exceeding 75 V VDS, including inductive ringing, causes avalanche failure - add a snubber or TVS clamp if reverse recovery or stray inductance generates overshoot. (3) Operating above 175 C junction temperature causes long-term reliability degradation - measure Tj under worst-case conditions. (4) The body diode is suitable for synchronous rectification but not for continuous forward conduction above 30 A - use an external Schottky diode for hard-switched bridge applications.
To minimize EMI from high di/dt switching edges, add an RC snubber (10 ohm + 1 nF typical) across the drain-source to slow the switching edge to 5-10 ns. Use a ferrite bead or common-mode choke on the input/output DC rails. The PG-TDSON-8-7 package has lower parasitic inductance than TO-220 or DPAK alternatives, but at 100 A peak current, ringing at 50-200 MHz can still exceed CISPR 22 Class B limits. Measure with a near-field probe and adjust gate resistance to trade off switching loss against EMI margin.
