ROHM 2SA1037AK/2SA1576A/2SA1774/2SA2029/2SA933AS General Purpose Transistor Datasheet
The document lists the key features, structure, and external dimensions of the ROHM PNP silicon transistors, followed by absolute maximum ratings such as collector‑base voltage, collector‑emitter voltage, and power dissipation. Electrical characteristics including hFE classifications, saturation voltage, and transition frequency are detailed, along with packaging codes and ordering units.
Several electrical characteristic curves are presented, showing grounded‑emitter propagation, output characteristics, DC current gain versus collector current, saturation voltage, gain‑bandwidth product, and output capacitance across various test conditions.
