Frequently Asked Questions

Q: Is a heatsink required for the 2SD526?
A: Yes, when operating near maximum current (4A), a suitable heatsink is highly recommended to maintain junction temperature within safe limits and ensure long device life.

Q: What is the maximum power dissipation?
A: The 2SD526 can dissipate approximately 40W with an adequate heatsink. Without a heatsink, limit dissipation to roughly 1-2W depending on ambient temperature.

Notes

Heatsink mounting is essential for reliable operation above 1-2W dissipation. Always verify adequate thermal contact between the transistor case and heatsink surface.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
