CSG20N65A

CSG20N65A is optimized for +15V turn-on and -8V to -15V turn-off gate drive: (1) +15V VGE(on) ensures low VCE(sat) and minimizes conduction losses. (2) Negative turn-off voltage (-8V to -15V) prevents false turn-on due to dv/dt and Miller effect. (3) Gate resistor selection affects switching speed and EMI - typical values are 10-22Ω for turn-on and 5-15Ω for turn-off. The gate drive should provide 2-4A peak current for fast switching. CR Micro provides recommended gate drive circuits and PCB layout guidelines.

CSG20N65A has a short-circuit withstand time (tSC) of 10μs minimum at VGE = 15V, VCC = 400V, and starting Tj = 150°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. CR Micro recommends using gate drivers with integrated desaturation protection for reliable short-circuit protection.

CSG20N65A in TO-247 package has the following thermal characteristics: (1) Junction-to-case thermal resistance RthJC = 0.6°C/W (IGBT) and 1.2°C/W (diode). (2) Junction-to-ambient thermal resistance RthJA = 40°C/W (without heatsink). (3) Maximum junction temperature Tj(max) = 175°C. For continuous operation at 40A with 1.6V VCE(sat), the conduction loss is 64W, requiring a heatsink with thermal resistance of approximately 1°C/W or better to maintain junction temperature below 125°C at 25°C ambient.

Yes, CSG20N65A is specifically optimized for induction cooker applications. Its characteristics make it ideal for this demanding application: (1) 650V rating provides adequate margin for 220V AC input after rectification (~310V DC). (2) Low VCE(sat) of 1.6V minimizes conduction losses at high currents typical in induction cookers (20-40A). (3) Fast switching with controlled dv/dt reduces EMI and audible noise. (4) 10μs short-circuit withstand provides reliable protection during pan detection failures. (5) Built-in fast recovery diode simplifies resonant tank design.

CSG20N65A's built-in anti-parallel diode features: (1) Fast reverse recovery time trr = 50ns typical at IF = 20A. (2) Soft recovery characteristics to minimize voltage overshoot and EMI. (3) Low forward voltage VF = 1.8V typical at IF = 20A. (4) Reverse recovery charge Qrr = 150nC typical. These characteristics make the diode suitable for high-frequency freewheeling applications in inverter circuits. The soft recovery minimizes dv/dt stress on the complementary IGBT and reduces EMI filtering requirements.
