Switch-Mode Power Supplies (SMPS)

The STB9N60M2 is ideal for SMPS primary-side switching. Its 600V rating handles universal input (85-265V AC) with margin, and the low on-resistance (0.55 ohm) minimizes conduction losses, improving efficiency. The low gate charge (18 nC) enables fast switching, reducing switching losses at high frequencies. In a typical flyback converter, the MOSFET switches at 100 kHz, and the fast body diode reduces reverse recovery losses. Proper snubber circuits may be needed to manage voltage spikes from transformer leakage inductance.

⚑

Power Factor Correction (PFC)

In boost PFC circuits, the STB9N60M2 operates at high switching frequencies (typically 100-200 kHz) to shape the input current waveform. Its low gate charge and fast switching reduce switching losses, while the 600V rating provides headroom for output voltages up to 400V. The avalanche ruggedness (300 mJ) ensures survival during transient overvoltages. A continuous conduction mode (CCM) PFC design with this MOSFET can achieve efficiency above 95%.

Selection Guide

Choose the STB9N60M2 when you need a 600V N-channel MOSFET in a surface-mount D2PAK package for high-voltage power conversion. It is ideal for SMPS, PFC, LED drivers, and motor control where low on-resistance and fast switching are important. If you prefer a through-hole package, consider the STB9N60M2-1 (same die, TO-220). For enhanced performance with lower on-resistance, the STB9N60M2-EP is a drop-in upgrade. Cross-brand alternatives like the Infineon IPP60R099CP offer lower on-resistance but are in TO-220 and not pin-compatible, requiring PCB redesign. The onsemi FCP7N60 is a similar TO-220 option. For surface-mount designs, the STB9N60M2 is the best choice among these.

Key Differentiators

  • Low on-resistance (0.55 ohm) reduces conduction losses (vs IPP60R099CP)
  • High avalanche energy (300 mJ) ensures robustness (vs FCP7N60)
  • D2PAK package for surface-mount assembly (vs STB9N60M2-1)

Design Notes

The D2PAK package has a junction-to-ambient thermal resistance of 62.5Β°C/W. At 7A and 0.55 ohm, power dissipation is approximately 27W, which would cause a temperature rise of 1687Β°C without a heatsink. Therefore, a heatsink or large copper area is mandatory for continuous operation at high currents. For example, at 3A, dissipation is 5W, requiring a heatsink with thermal resistance below 20Β°C/W to keep junction temperature below 150Β°C at 25Β°C ambient.

Place the gate drive circuit close to the MOSFET to minimize parasitic inductance. Use a gate resistor (typically 10-100 ohm) to control switching speed and reduce EMI. Ensure the source pin has a low-inductance path to the controller ground. For high-frequency operation, use a Kelvin source connection if available to reduce gate drive loop inductance.

Do not exceed the maximum gate-source voltage of Β±30V. Use a zener diode or TVS for gate protection if the gate drive can overshoot. Also, ensure the drain-source voltage does not exceed 600V, especially during switching transients. An RC snubber across the drain-source may be needed to limit voltage spikes in inductive load switching.
