The onsemi NGTB20N120IHRWG is a Field Stop (FS) Trench Insulated Gate Bipolar Transistor with an integrated monolithic free-wheeling diode. It operates at a collector-emitter voltage of 1200 V and supports a continuous collector current of 40 A at 25°C case temperature, derating to 20 A at 100°C. The device features a low saturation voltage of 2.10 V at 20 A and a turn-off switching loss of 0.45 mJ under standard test conditions. It is housed in a TO-247 package with a thermal resistance junction-to-case of 0.39 °C/W and functions within a junction temperature range of -40°C to +175°C.
Verify the ordering suffix 'WG' confirms lead-free packaging status as documented in the datasheet. Confirm that the specific revision matches the required technical specifications. Ensure the component is sourced from authorized channels to guarantee authenticity and compliance with RoHS standards. Check for any specific handling requirements related to the TO-247 package during assembly.
Select this component for applications requiring robust field stop technology and low on-state voltage. Consider the 1200 V rating and 40 A current capability for high-power switching circuits. Evaluate the thermal management needs based on the 0.39 °C/W junction-to-case resistance. Verify compatibility with soft-switching topologies where minimal switching loss is critical for system efficiency.
This part belongs to onsemi's NGTB series of Field Stop IGBTs, designed for cost-effective single-die solutions. It shares the FS Trench architecture with other models in the lineup but offers specific current and voltage ratings tailored for demanding switching environments. The series targets industrial and consumer power conversion applications requiring high reliability.
Direct replacements must match the 1200 V rating, TO-247 package, and Field Stop technology. Verify equivalent current ratings and switching characteristics. Consult the official datasheet for pinout compatibility and thermal parameters before substituting.
