Frequently Asked Questions

1.Can STPS2045CT be replaced with B20100G?
The parameters of 85N3L are VDSS=30V, RDS(on)<0.0054 ohms, ID=80A. The parameters of 85T03 are VDSS=30V, RDS(on)=6mΩ, ID=75A, the two parameters are close, and it should be possible to substitute in the circuit where the working current is not too limited. If it is used in the CPU power supply circuit of a computer motherboard, all the corresponding tubes in each phase of the power supply should be replaced with the same type of tube. If only one of them is replaced, it is very likely to burn again.
2.Can the computer power supply STPS300H100CT Schottky diode be replaced with STPS2045CT?
STPS300H100CT is 100v/30a, single tube), STPS2045CT is 45v/20a, two tubes can be replaced, but not as good as the original one, the current is small and the current is two tubes.
3.What can be replaced with STPS2045CT?
ST STMicroelectronics’ 20A 45V power Schottky diodes can be replaced by Schottky diodes that reach or exceed this value.
