The IRFZ44E is one tidy, powerful FET. And yes, it's still in a through-hole, TO-220AB shape. This bad-boy has a very low on-resistance of only 0.023 ohms! That...that's amazing! Especially when compared to the transistors "back in my day..." .

FET Type	N-Channel
Drain-to-Source Voltage (Vdss)	60V
Current - Continuous Drain (Id) @ 25° C	48A
Rds On (Max) @ Id, Vgs @ 25° C	23 mOhm @ 29A, 10V
Input Capacitance (Ciss) @ Vds	1360pF @ 25V
Power - Max	110W
Gate Charge (Qg) @ Vgs	60nC @ 10V
