Frequently Asked Questions
What is the recommended gate drive voltage for GD50HFL120C1S?
GD50HFL120C1S is optimized for +15V turn-on and -8V turn-off gate drive: (1) +15V VGE(on) ensures low VCE(sat) and minimizes conduction losses. (2) -8V negative turn-off voltage prevents false turn-on due to dv/dt and Miller effect. (3) Gate resistor selection affects switching speed and EMI - typical values are 15-33Ω for turn-on and 10-22Ω for turn-off. The gate drive should provide 2-4A peak current for fast switching. Starpower provides recommended gate drive circuits and PCB layout guidelines.
Contact our FAE team for gate driver IC recommendations and gate drive circuit design.
What is the thermal resistance of GD50HFL120C1S?
GD50HFL120C1S in 34mm package has the following thermal characteristics: (1) Junction-to-case thermal resistance RthJC = 0.65K/W (IGBT) and 1.2K/W (diode). (2) Maximum junction temperature Tj(max) = 150°C. (3) Recommended operating junction temperature Tj(op) = -40°C to +125°C. For continuous operation at 50A with 1.7V VCE(sat), the conduction loss is 85W, requiring a heatsink with thermal resistance of approximately 0.5K/W or better to maintain junction temperature below 125°C at 40°C ambient. Thermal interface material with low thermal resistance (0.1-0.2K·cm²/W) is recommended.
Contact our FAE team for thermal simulation and heatsink selection guidance.
Can GD50HFL120C1S be used for servo drive applications?
Yes, GD50HFL120C1S is well-suited for servo drive applications. Its characteristics make it ideal for this demanding application: (1) 1200V rating provides adequate margin for 380-480VAC servo systems. (2) 50A current rating supports servo drives up to 15-20kW. (3) Fast switching with controlled dv/dt reduces motor insulation stress. (4) Low VCE(sat) minimizes losses during frequent acceleration/deceleration cycles. (5) 10μs short-circuit withstand provides reliable protection during output faults. The module's compact 34mm package fits standard servo drive mechanical designs.
Contact our FAE team for servo drive design support and PWM frequency optimization.
What is the short-circuit withstand time of GD50HFL120C1S?
GD50HFL120C1S has a short-circuit withstand time (tSC) of 10μs minimum at VGE = 15V, VCC = 800V, and starting Tj = 125°C. This specification ensures reliable protection during output short-circuit conditions. The IGBT desaturation detection circuit should detect the fault and turn off the IGBT within 10μs to prevent device damage. Starpower recommends using gate drivers with integrated desaturation protection for reliable short-circuit protection. The module has been tested for repetitive short-circuit robustness under specified conditions.
Contact our FAE team for short-circuit protection circuit design and desaturation detection implementation.
What is the diode recovery characteristics of the built-in anti-parallel diode?
GD50HFL120C1S's built-in anti-parallel diode features: (1) Fast reverse recovery time trr = 120ns typical at IF = 25A. (2) Soft recovery characteristics to minimize voltage overshoot and EMI. (3) Low forward voltage VF = 1.8V typical at IF = 25A. (4) Reverse recovery charge Qrr = 1.2μC typical. These characteristics make the diode suitable for high-frequency freewheeling applications in inverter bridges. The soft recovery minimizes dv/dt stress on the complementary IGBT and reduces EMI filtering requirements. The diode is rated for the same current as the IGBT for reliable operation.
Contact our FAE team for diode recovery characteristics data and snubber circuit design.
Is GD50HFL120C1S suitable for automotive applications?
GD50HFL120C1S is built on an industrial-grade platform. For automotive applications, Starpower offers AEC-Q101 qualified versions with enhanced reliability testing. The automotive versions undergo additional testing including: (1) Temperature cycling (-40°C to +150°C). (2) High-temperature operating life (HTOL) at 150°C.
