The SSM2220S is a bipolar dual transistor array in a very small outline, available in SOT-23 package. It is designed to be an extremely versatile part, suitable for a variety of applications such as precision analog and mixed signal amplifiers and receiver circuits, power supplies, switching power converters, power amplifiers, various linear and non-linear signal processing applications.

The SSM2220S features two identical transistors in a single package, which allows for double the current and voltage ratings of a single transistor in a much smaller and lighter package. The transistors have excellent thermal characteristics, with a thermal resistance of 25°C/W at the junction. This allows the device to operate at high power levels without excessive heat dissipation.

The SSM2220S operates in both bipolar and field-effect configurations. In the bipolar configuration, the transistors are biased with two VBEs (base-emitter voltages) per transistor setting the current gain of the transistor, which is usually configured as a transistor amplifier. In the field-effect configuration, the base current is modulated by a gate voltage so the gain of the transistor can be adjusted as required, which can be used as an adjustable current source or amplifier.

The SSM2220S is also used in high-voltage switching circuits. This is possible due to its integrated protection diodes, allowing for a wide input voltage range with its protection capacitance. Additionally, the device contains a decoupling capacitor, allowing for cleaner operation and better signal stability.

The SSM2220S is also used in power modulation applications. It has an impressive transient response time as well as excellent frequency response up to 10MHz. It is also very efficient in power dissipation with its low noise side control (Rac) and low power consumption, allowing for higher performance with lower power budget.

The SSM2220S is also used in automotive and industrial application. It has an integrated ESD protection and can operate over an extended temperature range, making it ideal for use in automotive and industrial applications. It also has a very high current capacity, making it perfect for use in power switching and motor control applications.

Overall, the SSM2220S is an extremely versatile and useful device for a wide range of applications. Its small outline, high current capacity, thermal characteristics and protection diodes make it ideal for use in a variety of analog and digital applications. Additionally, its high frequency response, low power consumption, and extended temperature range make it perfect for use in automotive and industrial applications.
