Cross for 3DD13005MD : Jilin Sino-Microelectronics Co., LTD

3DD13005MD is a series of high power NPN transistors from a company called Jilin Sino-Microelectronics Co., LTD, the following specifications are listed on the datasheet:

Specification Name Value
Ic (Collector Current) 4A
Vceo (Collector Emitter Voltage Breakdown) 400V
Pc(TO-220HF)* (Maximum Power) 35W
Pc(TO-220)* (Maximum Power) 75W

The * points out that the datasheet separated power ratings based on the packages they had available for this kind of transistor, they listed two types of transistor outline TO-220HF and TO-220.

Here is a list of alternates that are 35W rated: https://www.digikey.com/short/p2fnm1
Here is a list of alternates that are 75W rated: https://www.digikey.com/short/p2fnhp

These lists are generic based on the ratings above (not the full list of potential ratings as that will be particular to each application). Technically, you could use higher current ratings above 4A and higher wattage ratings. The lists narrow down options as close as possible to the original datasheet.
