Product details
Overview
BSC159N10LSFGATMA1 from Infineon Technologies is a 100 V, 15.9 mΩ (typ. @ VGS = 10 V), N-channel enhancement-mode MOSFET in PG-TSDSON-8 package, optimized for high-frequency synchronous rectification and DC-DC conversion in server VRMs and telecom power supplies.
For engineers reviewing the BSC159N10LSFGATMA1 datasheet, BSC159N10LSFGATMA1 pinout, BSC159N10LSFGATMA1 application, or BSC159N10LSFGATMA1 equivalent, key selection criteria include RDS(on) at 4.5 V and 10 V, gate charge (Qg = 17 nC), thermal resistance (RthJC = 1.4 K/W), and avalanche ruggedness (EAS = 33 mJ).
Technical Context
This MOSFET employs Infineon's OptiMOS™ 5 technology, featuring a trench-gate superjunction structure that enables low conduction loss while maintaining fast switching speed. It supports unclamped inductive switching (UIS) with guaranteed EAS rating and operates with gate threshold voltage VGS(th) between 1.8 V and 2.8 V.
The device is qualified per AEC-Q101 for industrial reliability and features a thermally enhanced TSDSON-8 package with exposed drain pad for low-junction-to-case thermal resistance. Its gate charge profile (Qgs = 4.2 nC, Qgd = 5.5 nC) supports efficient zero-voltage switching (ZVS) in resonant topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-frequency power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N10F7 | RDS(on) = 13.5 mΩ @ 10 V, Qg = 21.5 nC, RthJC = 1.6 K/W | Higher gate charge increases switching loss in >600 kHz designs; slightly better conduction loss at high ID | Select when lowest RDS(on) dominates over switching frequency constraints |
| IRF7759L2TRPBF | RDS(on) = 17.5 mΩ @ 10 V, Qg = 14.5 nC, RthJC = 1.8 K/W, TO-252 package | Larger footprint and higher thermal resistance limit use in space-constrained POLs; lower Qg benefits ZVS designs | Select when board area permits DPAK and gate drive strength is limited |
Compared with STL130N10F7 and IRF7759L2TRPBF, BSC159N10LSFGATMA1 delivers optimal balance of conduction loss, switching speed, and thermal performance in compact 3.3×3.3 mm layouts-critical for multi-phase VRMs where per-phase current density exceeds 15 A/mm².

FAQ
What is the maximum continuous drain current at TC = 100 °C?
The BSC159N10LSFGATMA1 supports 25 A continuous drain current at case temperature of 100 °C, derated from 42 A at 25 °C using its specified thermal resistance (RthJC = 1.4 K/W) and maximum junction temperature (TJ = 150 °C). This rating assumes adequate PCB copper area for heat spreading.
Does this MOSFET require a negative gate voltage for reliable turn-off?
No. The device has a gate threshold voltage range of 1.8–2.8 V and exhibits no parasitic turn-on under typical 0 V to 12 V gate drive. Negative gate bias is not required; however, a 0 V gate return (not floating) is mandatory during off-state to prevent spurious conduction from capacitive coupling.
Is the PG-TSDSON-8 package lead-free and RoHS-compliant?
Yes. The BSC159N10LSFGATMA1 uses lead-free solderable terminations and complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30 °C/60% RH without dry pack requirements.
Can this MOSFET be used in linear (analog) regulation mode?
No. It is not characterized or qualified for linear-mode operation. The Safe Operating Area (SOA) curve shows limited DC capability beyond 10 A at VDS > 20 V due to thermal instability. Use only in switched-mode applications with defined duty cycle and heatsinking per datasheet SOA limits.
