CPH3122-TL-E Description

Short technical summary and product information.

The CPH3122-TL-E is a PNP bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications requiring moderate voltage and current handling. Key electrical ratings include a maximum collector-emitter voltage of -30V, a continuous collector current of -3A (pulse up to -5A), and a power dissipation of 0.9W when mounted on a ceramic substrate.

 

The transistor offers a DC current gain (hFE) of 200 minimum and 560 typical at VCE = -2V and IC = -500mA. It features low collector-emitter saturation voltage, with typical values of 180mV at IC = -1.5A and IB = -30mA, and 120mV at IC = -1.5A and IB = -75mA. The gain-bandwidth product (fT) is typically 400MHz, making it suitable for high-speed switching applications. Switching times include a turn-on time of 50ns, storage time of 270ns, and fall time of 27ns.

 

The device is housed in a CPH3 surface mount package (SC-59/SOT-23 equivalent) with a low profile of 0.9mm height, enabling compact designs. It is supplied in tape and reel packaging with 3000 pieces per reel. The lead finish is tin (Sn) and the part is lead-free (Pb Free) as per the datasheet.

 

Typical applications include relay drivers, lamp drivers, motor drivers, and flash circuits. The transistor's high current capacity and low saturation voltage make it efficient for driving inductive loads.
