Product details

Overview

BSC042N03MSGATMA1 from Infineon Technologies is an N-channel OptiMOS™3 Power-MOSFET optimized for 5 V gate drive in notebook CPU VRMs, VGA power stages, and point-of-load (POL) converters. It delivers 4.2 mΩ R_DS(on) at V_GS = 10 V, 5.4 mΩ at 4.5 V, 93 A continuous drain current (T_C = 25 °C), and 100% avalanche tested robustness for high-reliability DC-DC switching.

For engineers reviewing the BSC042N03MSGATMA1 datasheet, BSC042N03MSGATMA1 pinout, BSC042N03MSGATMA1 application, or BSC042N03MSGATMA1 equivalent, key selection criteria include its low gate charge × R_DS(on) figure-of-merit (FOM), JEDEC-qualified thermal performance, and PG-TDSON-8 package suitability for high-density synchronous buck topologies.

Technical Context

This MOSFET employs a trench-based silicon process to achieve ultra-low on-resistance with fast switching dynamics. Its 3200 pF input capacitance (C_iss) and 940 pF output capacitance (C_oss) support high-frequency operation up to 1 MHz in SMPS designs.

The device features a 2.2 K/W junction-to-case thermal resistance (R_thJC) and is characterized for stable gate threshold voltage (1–2 V) across –55 to 150 °C, enabling reliable turn-on control in thermally constrained POL modules.

FAQ

Is BSC042N03MSGATMA1 suitable for synchronous rectification in 4.5 V gate-drive applications?

Yes. Its guaranteed R_DS(on) of 5.4 mΩ at V_GS = 4.5 V and gate threshold voltage range of 1–2 V ensure full enhancement and low conduction loss when driven directly by standard 5 V logic or dedicated gate drivers. The device is explicitly optimized for 5 V driver applications including notebook VRMs and POL converters.

What is the maximum safe operating temperature for continuous operation?

The junction temperature must not exceed 150 °C. At T_C = 100 °C, the device supports 52 A continuous drain current with V_GS = 4.5 V. Derating curves in the datasheet show linear reduction from 82 A at 25 °C to zero at 150 °C ambient case temperature, assuming proper PCB thermal design with ≥6 cm² copper area.

Does this MOSFET include an integrated body diode, and how is it characterized?

Yes, it features a monolithic parasitic body diode with forward voltage V_SD = 0.84–1.1 V at I_F = 30 A and T_j = 25 °C. Reverse recovery charge Q_rr is specified at 15 nC under 15 V reverse bias and 400 A/µs di/dt, confirming suitability for synchronous rectification with controlled dead-time management.

Can BSC042N03MSGATMA1 be used in automotive applications?

While not AEC-Q101 qualified, its JEDEC qualification, –55 to 150 °C operating range, and 100% avalanche testing support industrial and computing applications with automotive-adjacent thermal and reliability requirements. For certified automotive use, Infineon's DMTH3007LPSQ-13 is the functionally aligned AEC-Q101 alternative.
