2SK3548 Transistors Explained / Description:
2SK3548 is an N channel MOSFET available in TO-3P package. The pin layout of the transistor is as follows: the first pin is “Gate”, second pin is “Drain” and the third pin is “Source”. Considering the absolute maximum ratings of the MOSFET the drain-to-source voltage is 900V, continuous drain current is 10A, pulsed drain current is ±40V, gate-source voltage is ±30V, power dissipation is 180W and max storage and operating temperature is from -55 to +150 °C.
Understanding the features of this MOSFET, one of the main feature of this MOSFET is its drain-to-source voltage of 900V, which means it can supply upto 900V to the load. Another good feature is its 10A current capability, the low RDS(on) resistance of 1.4 Ohms improves it performance by reducing power losses, voltage drop and heat generation, the rapid turn on time of typical 23ns and turn off time of 17ns makes it ideal to use in SMPS, PWM and other high frequency applications, etc. All these features make it a reliable transistor for many commercial and industrial applications.
Where We Can Use it & How to Use:
2SK3548 can be used in many commercial and industrial applications such as controller circuits, industrial automation, power electronics, amplification, lighting, automotive, switching, etc. The detailed list of its applications can be found under the “Applications” heading below.
For using the MOSFET first understand that the minimum voltage to open the MOSFET is 3.0V but on that voltage it will not become fully ON but only a little and you will get little current at its output. To achieve its full current at its ouput you will have to provide at least 10V to its gate. But it is suggested to not use it to its max current which is 10A and stay 20% below and only use 8A.
Applications:
Inverters
Solar Inverters
UPS
Computer Power Supplies
Motor Drivers
UPS Systems
Audio Amplifiers
Light Control Systems
Motor Control (Fans, Pumps, compressors etc.)
Voltage Regulators
Switching Power Supplies (Telecommunications Supplies, LED Drivers etc.)
DC to DC Converters
Motor Control (Fans, Pumps, compressors etc.)
Safe Operating Guidelines
Here are some safe operating guidelines for the MOSFET.
- Do not use it to its absolute maximum ratings and stay at least 20% below from these ratings.
- So the maximum continuous drain current is 10A but according to the 20% rule only use 8A.
- Max drain to source voltage is 900V so by following the 20% rule do not drive load of more than 720V
- Always use a suitable heatsink.
- Storage and operating temperature should be between these limits -55°C to +150 °C.
