Selecting power semiconductors involves: (1) Voltage rating - choose at least 20-30% margin above maximum operating voltage; (2) Current rating - based on thermal constraints and RMS current requirements; (3) Switching frequency - MOSFETs for high frequency, IGBTs for lower frequency high power; (4) Thermal requirements - evaluate power dissipation and cooling needs; (5) Package - select based on power dissipation and mounting requirements. IXYS offers MOSFETs, IGBTs, diodes, and thyristors for various applications. Contact LiTong FAE for personalized selection guidance.

Consider voltage, current, frequency, and thermal requirements when selecting power semiconductors.

IXYS product lead times vary by product type and volume: (1) Standard catalog products - typically 8-12 weeks for common configurations; (2) High-volume orders - 10-14 weeks for large quantities; (3) Custom configurations - 14-20 weeks for special requirements; (4) Samples - 2-4 weeks for engineering samples.
