Additional Details

The KSA1201 is typically available in a TO-92 package. Key specifications include collector-emitter voltage (VCEO), collector-base voltage (VCBO), emitter-base voltage (VEBO), collector current (IC), and power dissipation (PD). The current gain (hFE) is a critical parameter that determines the transistor's amplification capability. Consult the datasheet for specific values and operating characteristics. It's essential to observe the maximum ratings to avoid damage to the transistor.

The KSA1201 is often used in complementary pairs with the KSC2690 NPN transistor in push-pull amplifier configurations. Ensure proper heat sinking is provided if the transistor is operated at high power levels. The device is typically RoHS compliant.
