The minimum DC current gain (hFE) for the BUF420AW

Could you tell me the minimum DC current gain(hFE) for the BUF420AW？

The curves show the typical values for the two junction temperatures 25°C and 125°C.

Welcome @maeda, to the community!

There is no minimum DC current gain, but the data sheet, page 4 shows the curves for the DC current gain in the diagrams for two different collector-emitter voltages and depending on the collector current.

Hope that answers your question?

Thank you for your advice.

Are the curves shown the average values?
