Choosing a replacement for the GT30F124

A drop-in substitute for the GT30F124 should match its polarity and meet or exceed every rating listed above.

Mechanically, check the replacement against the TO220SIS footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions
