STMicroelectronics STWA72N60DM2AG

Overview

STWA72N60DM2AG from STMicroelectronics is an AEC-Q101 qualified automotive-grade N-channel 600 V Power MOSFET in TO-247 long leads package, featuring 37 mΩ typ. R_DS(on), 66 A continuous drain current at T_C = 25 °C, and fast-recovery body diode with 150 ns trr (T_J = 25 °C). It delivers low gate charge (121 nC), high dv/dt ruggedness (50 V/ns), and 100% avalanche tested performance for ZVS phase-shift and bridge-topology converters.

For engineers reviewing the STWA72N60DM2AG datasheet, STWA72N60DM2AG pinout, STWA72N60DM2AG application, or STWA72N60DM2AG equivalent, key selection criteria include its MDmesh DM2-series fast-recovery diode integration, 470 pF C_oss,eq at 480 V, 1500 mJ E_AS, and thermal resistance of 0.28 °C/W (R_thJC).

Technical Context

This MOSFET employs ST's MDmesh DM2 technology to co-optimize conduction loss (R_DS(on) = 37 mΩ typ.) and switching performance (Q_gd = 61 nC, Q_gs = 26 nC), enabling high-frequency operation in resonant topologies. Its Zener-protected gate and 100% unclamped inductive switching (UIS) testing ensure robustness under transient overvoltage conditions.

The integrated fast-recovery body diode achieves Q_rr = 0.75 µC and trr = 150 ns at 25 °C - critical for minimizing commutation losses in hard-switched bridges. Thermal design is supported by a low junction-to-case resistance (0.28 °C/W) and SOA-rated operation up to 10 ms at 100 A/300 V.

FAQ

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

The STWA72N60DM2AG supports 42 A continuous drain current at T_C = 100 °C, as specified in Table 1 of DS12726 Rev 2. This derating reflects thermal limits under sustained conduction, with SOA curves confirming safe operation up to 10 ms at 100 A/300 V.

Does this MOSFET require external gate protection?

No external gate protection is required: the device integrates Zener protection between gate and source, supporting ±25 V V_GS ratings. Gate leakage remains ≤ ±5 µA at ±25 V, and the 2 Ω intrinsic gate resistance helps dampen ringing without added series resistance.

How does the body diode performance compare to standard MOSFETs?

Its body diode achieves trr = 150 ns and Q_rr = 0.75 µC at 25 °C - over 3× faster and 5× lower Q_rr than typical 600 V planar MOSFETs. At 150 °C, trr rises to 250 ns and Q_rr to 2.5 µC, maintaining usable performance in high-temperature automotive environments.

Is the TO-247 long leads package compatible with standard TO-247 heatsinks?

Yes - the TO-247 long leads package uses industry-standard mechanical dimensions (e.g., D = 21.00 mm, E = 15.80 mm) and mounting hole spacing. The "long leads" designation refers to lead length only; thermal interface and mounting torque (0.5–0.8 N·m) match standard TO-247 specifications per Table 8.
