MOSFET equivalent

[Askic]

Hello guys,

I have a shorted MOSFET with the following characteristics:

Type Designator: MDF4N65BTH
Type of Transistor: MOSFET
Type of Control Channel: N -Channel
Maximum Power Dissipation (Pd): 35 W
Maximum Drain-Source Voltage |Vds|: 650 V
Maximum Gate-Source Voltage |Vgs|: 30 V
Maximum Gate-Threshold Voltage |Vgs(th)|: 4 V
Maximum Drain Current |Id|: 4 A
Maximum Junction Temperature (Tj): 150 °C
Rise Time (tr): 22 nS
Drain-Source Capacitance (Cd): 61 pF
Maximum Drain-Source On-State Resistance (Rds): 2.2 Ohm
Package: TO-220F


Can I use the following as a replacement (in TV supply board)?
Type Designator: STP10NK70ZFP
Type of Transistor: MOSFET
Type of Control Channel: N -Channel
Maximum Power Dissipation (Pd): 35 W
Maximum Drain-Source Voltage |Vds|: 700 V
Maximum Gate-Source Voltage |Vgs|: 30 V
Maximum Gate-Threshold Voltage |Vgs(th)|: 4.5 V
Maximum Drain Current |Id|: 8.6 A
Maximum Junction Temperature (Tj): 150 °C
Total Gate Charge (Qg): 64 nC
Maximum Drain-Source On-State Resistance (Rds): 0.85 Ohm


Thank you

Re: MOSFET equivalent

probably.

if you had the gate capacitance i could give a better answer, the gate capacitance limits switching speed - lower is better

The Ciss for the MDF4N65BTH is 518 pF typical.

The Ciss for the STP10NK70ZFP is 2000 pF typical. https://cdn.badcaps-static.com/pdfs/...f9e2115c39.pdf

Re: MOSFET equivalent

ouch.
i hope the driver has a strong push/pull output!
