2SA733 PNP Transistor 50V 150mA – TO-92 | Hottech

Hottech

The PNP Transistor series from Hottech is designed for general-purpose switching and amplification applications across a wide range of electronic systems. With collector-base voltage ratings from -30V to -300V, collector current up to 1.5A, and high current gain (hFE: 70 to 1000), this series provides flexible solutions for both low-power and medium-power circuit designs.

These transistors feature low saturation voltage, stable gain characteristics, and reliable switching performance, making them suitable for analog and digital applications. High-voltage models such as MMBTA92 and MMBTA94 support specialized applications requiring higher voltage handling.

Available in both TO-92 and compact SOT-23 packages, the series supports traditional through-hole as well as space-saving surface-mount PCB designs.

This series is widely used in electric tools, smart speakers, portable power supplies, massagers, hand warmers, network set-top boxes, cameras, smart locks, and display systems, where efficient switching and amplification are required.
