Product Description

The **2SB1440 Transistor** is a robust PNP Power Transistor designed for high-current switching and amplification applications. Featuring a collector-emitter voltage (VCE) of -50V and a continuous collector current (IC) rating of -5A, it operates efficiently within a voltage range of -50V to -5V and a temperature range of -55°C to 150°C. This transistor is commonly integrated into power management circuits, motor drivers, and industrial automation systems due to its high power dissipation capability (25W). As a Sanyo 2SB1440 Replacement, it offers compatibility with legacy designs. While its rugged construction ensures reliability in harsh environments, drawbacks include potential heat generation requiring adequate thermal management. Typical uses include audio amplifiers, voltage regulators, and industrial control modules, where stable performance under load is critical.
