Product details
Overview
BSC0302LSATMA1 from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TDSON-8 package, rated for 120 V VDS, 8.0 mΩ RDS(on) at VGS = 10 V, 99 A continuous drain current, and 150 °C operation - optimized for high-frequency switching and synchronous rectification in DC-DC converters and motor drives.
For engineers reviewing the BSC0302LSATMA1 datasheet, BSC0302LSATMA1 pinout, BSC0302LSATMA1 application, or BSC0302LSATMA1 equivalent, key selection criteria include gate charge (Qg = 79 nC), output charge (Qoss = 79 nC), avalanche ruggedness (EAS = 377 mJ), thermal resistance (RthJC = 0.45 °C/W), and internal body diode performance (VSD = 0.88 V @ 50 A).
Technical Context
This OptiMOSTM 3 device uses trench-gate silicon technology to achieve low RDS(on) × Qg figure-of-merit (FOM) and fast switching with tr = 9 ns and tf = 13 ns under 10 V drive. Its gate threshold voltage (VGS(th) = 1.2–2.4 V) ensures reliable turn-on with standard logic-level controllers.
The integrated body diode supports synchronous rectification with trr = 107 ns and Qrr = 220 nC, while JEDEC-qualified reliability and 100% avalanche testing confirm robustness in inductive load switching and overvoltage transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 120 V - supports 48 V and 60 V bus systems with margin for voltage spikes in industrial and automotive power stages. |
| RDS(on), max | 8.0 mΩ @ VGS = 10 V - enables <1 W conduction loss at 50 A, critical for high-efficiency 100+ W DC-DC stages. |
| ID, cont | 99 A @ TC = 25 °C - delivers high current density in compact surface-mount layouts using bottom-side thermal pad. |
| Qg | 79 nC - determines gate driver power requirement and switching loss trade-off in 100–500 kHz applications. |
| EAS | 377 mJ - withstands single-pulse inductive energy without failure, enabling robust motor gate-drive and flyback snubber design. |
| RthJC | 0.45 °C/W - allows >150 W power dissipation with minimal junction-to-case temperature rise when mounted on copper heatsink. |
| VSD | 0.88 V @ IF = 50 A - reduces reverse conduction loss in synchronous buck topologies versus external Schottky diodes. |
Pinout & Package
PG-TDSON-8 package with exposed thermal pad on underside; pins 1–3 and pin 5–8 are source and drain terminals respectively, pin 4 is gate, and pin 5–8 share common drain connection for parallel current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source node for internal MOSFET cells; connects to PCB ground plane for low-inductance return path. |
| 4 | Gate | Control input requiring <79 nC charge; sensitive to ESD but compatible with 3.3 V/5 V logic drivers due to 1.2–2.4 V VGS(th). |
| 5, 6, 7, 8 | Drain | High-current drain node shared across four terminals; designed for direct connection to high-side switch node or bus rail. |
Key Features
| Feature | Design Value |
|---|---|
| N-channel logic-level operation | Turns fully on with 4.5 V gate drive (RDS(on) ≤ 9.5 mΩ), eliminating need for gate boosters in 5 V microcontroller-based designs. |
| 100% avalanche tested | Guarantees single-pulse ruggedness up to 377 mJ, enabling use in unclamped inductive switching without external protection. |
| Low Qg × RDS(on) FOM | Optimizes trade-off between switching speed and conduction loss - critical for efficiency in 300–1000 kHz SMPS designs. |
| Halogen-free & RoHS-compliant | Meets IEC61249-2-21 and EU RoHS Directive, supporting environmentally compliant industrial and consumer product certifications. |
| 150 °C maximum junction temperature | Enables operation in sealed enclosures or high-ambient environments (e.g., automotive under-hood, industrial PLCs) without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N10F7 | RDS(on) = 3.5 mΩ @ 10 V, but VDS = 100 V - lower conduction loss but reduced voltage margin for 48 V systems with transients. | Suitable for 24–36 V applications only; not recommended where 120 V surge immunity is required. | Select when board space is constrained and voltage margin is secondary to ultra-low RDS(on). |
| IXTP110N10L2 | TO-220 package, RDS(on) = 9.2 mΩ @ 10 V, Qg = 85 nC - higher gate charge and larger footprint than PG-TDSON-8. | Requires through-hole assembly and external heatsinking; less suitable for high-density SMT designs. | Prefer for prototyping or low-volume builds where thermal management flexibility outweighs size constraints. |
Compared with STL220N10F7 and IXTP110N10L2, BSC0302LSATMA1 uniquely balances 120 V rating, 8.0 mΩ RDS(on), and 79 nC Qg in a thermally enhanced surface-mount package - making it optimal for production-grade, high-power-density 48 V industrial and telecom power stages.

FAQ
What is the maximum continuous drain current for BSC0302LSATMA1 at 100 °C case temperature?
At TC = 100 °C, the maximum continuous drain current is 77 A, as specified in Table 2 of the datasheet under "Continuous drain current" with VGS = 10 V. This reflects thermal derating due to reduced heat dissipation capability at elevated case temperatures.
Does BSC0302LSATMA1 have an integrated body diode, and what is its forward voltage?
Yes, it includes an internal body diode with VSD = 0.88 V typical at IF = 50 A and Tj = 25 °C, as listed in Table 7. This diode supports synchronous rectification and freewheeling in half-bridge and buck configurations.
Can BSC0302LSATMA1 be driven directly by a 3.3 V microcontroller GPIO?
No - while it is a logic-level MOSFET, its minimum VGS(th) is 1.2 V and typical turn-on occurs above 2.4 V; full enhancement requires ≥4.5 V. A 3.3 V GPIO may partially turn it on, causing excessive RDS(on) and thermal risk. A level-shifting gate driver is recommended.
What is the safe operating area (SOA) limitation at 100 µs pulse width?
Per Diagram 3, at tp = 100 µs and TC = 25 °C, the SOA limits drain current to ~120 A at VDS = 20 V and ~40 A at VDS = 80 V. This defines maximum pulsed current under transient conditions without thermal runaway or second breakdown.
