Frequently Asked Questions

Q: What is the complementary NPN transistor for BD244?
A: The complementary NPN transistor is the BD243. Both are designed to work as a matched pair in symmetrical push-pull amplifier configurations.

Q: Does BD244 require a heatsink?
A: For continuous high-current operation (above 5A), a heatsink is strongly recommended. The TO-220 package includes a heatsink tab for mounting to a thermal dissipator.
