STD3NK50ZT4 Description

Short technical summary and product information.

The STMicroelectronics STD3NK50ZT4 is a Zener-Protected SuperMESH™ N-Channel MOSFET with a 500V drain-source voltage rating. It offers a typical on-resistance of 2.8 Ohms and a continuous drain current of 2.3A at 25°C.

 

This MOSFET is designed for high voltage applications and features extremely high dv/dt capability and improved ESD protection due to integrated Zener diodes. It is 100% avalanche tested and has minimized gate charge.

 

The device is housed in a TO-252-3, DPak (2 Leads + Tab), SC-63 package, suitable for surface mounting. Key electrical characteristics include a gate threshold voltage of 4.5V (max) at 50µA and a maximum gate-source voltage of ±30V. The maximum power dissipation is 45W at 25°C case temperature.

 

Applications include AC adaptors, battery chargers, switch mode power supplies (SMPS), and lighting. The operating temperature range is -55°C to 150°C (TJ).
