STY34NB50 Description

Short technical summary and product information.

The STMicroelectronics STY34NB50 is an N-Channel Power MOSFET utilizing the latest high voltage MESH OVERLAY process. This advanced design provides outstanding performance with an extremely low RDS(on) of typically 0.11 Ω and a maximum of 0.13 Ω at 17A and 10V gate drive.

 

With a drain-source voltage rating of 500V and a continuous drain current of 34A at 25°C, this MOSFET is suitable for high current and high speed switching applications. It boasts exceptional avalanche and dv/dt capabilities, along with minimized gate charge and reduced voltage spread.

 

The STY34NB50 is housed in a TO-247-3 package, designed for through-hole mounting. Its operating junction temperature is rated up to 150°C, with a total power dissipation of 450W at 25°C. This makes it ideal for demanding applications such as switch mode power supplies (SMPS) and DC-AC converters for welding equipment and uninterruptible power supplies.

 

Key electrical characteristics include a gate threshold voltage of 3.45V (typical) and a maximum gate-source voltage rating of ±30V. The input capacitance is 9100 pF at 25V, and the gate charge is 223 nC at 10V.
