STMicroelectronics STP60N043DM9

Overview

STP60N043DM9 from STMicroelectronics is a 600 V, 55 A N-channel super-junction Power MOSFET in TO-220 package, featuring 43 mΩ max R_DS(on), 78.6 nC total gate charge, and fast-recovery body diode with 165 ns trr and 1.06 μC Q_rr. It is engineered for high-efficiency LLC resonant converters and ZVS phase-shift bridge topologies.

For engineers reviewing the STP60N043DM9 datasheet, STP60N043DM9 pinout, STP60N043DM9 application, or STP60N043DM9 equivalent, key selection criteria include dv/dt ruggedness (120 V/ns), avalanche energy rating (839 mJ), low C_oss,eq (729 pF), and thermal resistance (R_thJC = 0.51 °C/W).

Technical Context

This device implements ST's MDmesh DM9 silicon super-junction technology with multi-drain process architecture, enabling ultra-low R_DS(on)/area while integrating a fast-recovery body diode optimized for hard- and soft-switching topologies. Its structure supports high dv/dt (120 V/ns) and di/dt (1300 A/μs) during recovery.

The MOSFET delivers stable 600 V breakdown voltage (V_(BR)DSS) across temperature, with gate threshold (V_GS(th)) tightly specified at 3.5–4.5 V and minimal drift up to 150 °C. Dynamic parameters-including Q_gd = 20 nC and C_iss = 4675 pF-are characterized at 400 V V_DS and 1 MHz.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The STP60N043DM9 supports 35 A continuous drain current at T_C = 100 °C, as specified in Table 1 of DS13931 Rev 5. This derating reflects thermal limits of the TO-220 package and ensures safe operation within SOA boundaries at elevated ambient conditions.

Is the body diode fully characterized for reverse recovery?

Yes-the source-drain diode is fully characterized with trr = 165 ns and Q_rr = 1.06 μC at T_J = 25 °C, and trr = 215 ns and Q_rr = 2.2 μC at T_J = 150 °C (Table 7). These values are measured under standardized inductive load conditions per Figure 15.

Does this MOSFET require a negative gate voltage for reliable turn-off?

No-STP60N043DM9 has a gate threshold voltage of 3.5–4.5 V and is fully enhanced with V_GS = 10 V. While ±30 V gate-source rating permits negative bias, it is not required for noise immunity; 0 V to 10 V drive suffices for robust switching in typical applications.

Can STP60N043DM9 replace older STP60N062 in existing designs?

Yes-with caveats: STP60N043DM9 offers lower R_DS(on) (43 mΩ vs. 62 mΩ) and faster diode recovery, but its higher Q_g (78.6 nC vs. 62 nC) may increase gate drive requirements. Layout and driver strength must be verified; no changes to pinout or package are needed.
