Introduction

The PUMB14,115 is a high performance array of fourteen NPN semiconductor devices operating in the bipolar (BJT) mode. Each individual device is well matched for these applications and provides protection against current overload and mis-application. In addition, the PUMB14,115 has a unique pre-biased configuration which allows for greater efficiency and longer power derating capability.

Device Description

The PUMB14,115 device is a high power bipolar (BJT) array of 14 NPN transistors. It has an integrated flow-over collector emitter diode built in to each device, providing overload and mis-application protection. The device is pre-biased, meaning that the current is already flowing through the device when it is supplied to the circuit. This pre-biasing feature allows for greater efficiency and wider power derating capabilities. The device is designed to operate in either current source or current sink configurations. The total power dissipation rating is a maximum of 62 W. The voltage range for the PUMB14,115 is 70 V.

Application and Working Principle

The PUMB14,115 is ideal for a variety of applications including light dimming, HVAC and motion control. In these applications, the PUMB14,115 is connected to a power supply and then to the load, such as a motor or a light bulb. The device is able to reduce the amount of current flowing through the load and the amount of power dissipated, allowing for greater efficiency and accuracy in dimming or controlling the load.The working principle of the PUMB14,115 is similar to that of other bipolar (BJT) arrays. The device acts as a voltage and/or current regulator. It is supplied with a chosen current and voltage, depending on the desired load. When connected to the power supply, the device allows the current to flow from the power supply to the load, reducing the current as needed. The device can also be used as a current source and sink, depending on the application.

Conclusion

The PUMB14,115 is a pre-biased array of fourteen NPN transistors designed for use in a variety of applications. The device offers overload and mis-application protection, as well as greater efficiency and longer power derating capabilities. It is suitable for use in light dimming, HVAC and motion control applications. The working principle of the device is similar to that of other bipolar (BJT) arrays. It acts as a voltage and/or current regulator, allowing for greater efficiency and accuracy in controlling the load.
