FAQ
1：What packages do BYD discrete IGBTs use?
BYD discrete IGBTs are available in TO-247 for higher current and better thermal performance, and TO-220 for compact lower power applications. Both are industry-standard through-hole packages compatible with standard PCB layouts.
2：Do BYD discrete IGBTs include built-in freewheeling diodes?
BYD offers both co-packed IGBTs with integrated freewheeling diodes and separate discrete diode products. For inductive loads, the co-packed version simplifies design. The separate diode option provides flexibility for custom circuit topologies.
3：What voltage platforms are available for discrete IGBTs?
BYD discrete IGBTs cover 650V, 1200V, and 1700V voltage platforms, matching the module product line. This allows consistent voltage platform selection across different form factors within the same system design.
