2SA1492 Transistor Explained / Description:
2SA1492 is a PNP power transistor available in TO-3PN transistor package. The transistor is designed to be used in audio applications and variety of other general purpose applications. Some of its good features are high collector-emitter voltage, good collector current and upto 130W of collector power dissipation.
The absolute maximum ratings of the transistor are collector-emitter voltage of -180V, collector current is -15A, collector-base voltage is -180V, emitter-base voltage is -6V, base current is -4A, collector power dissipation is 130W, junction temperature is 150°C and storage temperature is from -55°C to 150°C.
2SA1492 is available in three different hFE classifications which can be determined with the help of alphabet written below the part number if that alphabet is “O” then its DC current gain or hFE will be 50 to 80, if “P” then its hFE will be 80 to 130 and if “Y” then its hFE will be 130 to 180.
The transistor is designed to be used in audio and other general purpose applications such as driver circuits, power circuit, switching circuits and more.
How to Use This Transistor:
It is a BJT transistor so the using procedure will be same as we use any other BJT transistor by applying signal to its base pin, applying positive voltage to its emitter pin and driving the load from its collector pin (In switching circuits). And taking the amplified output from its collector pin (In amplifier circuits).
Applications:
Audio Amplifier Circuits
Audio Amplifier Stages
DC to DC Converters
Switching Regulators
PWM Circuits
Inductive Load switching
Battery Management Systems
Switching load of up to -8A
Safe Operating Guidelines:
Here are some important guidelines to safely operate the transistor.
- Do not use the transistor to its absolute maximum ratings and always stay 20% below from these ratings.
- Always use a suitable heatsink with the transistor.
- Check pin layout before using in your circuit.
- Always store and operate at temperatures above -55°C and under +150°C.
