This document introduces some general-purpose transistor products, including 2SA1037AK, 2SA1576A, 2SA1774, 2SA2029, and 2SA933AS. These transistors have excellent hFE linearity and complement other complementary transistor models such as 2SC2412K, 2SC4081, 2SC4617, 2SC5658, and 2SC1740S. The document also provides the external dimensions of each transistor model.
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.
| hFE classification | 120~270, 180~390, 270~560 |
|---|---|
| Transition frequency (fT) | up to 30 MHz |
hFE is classified as 120~270, 180~390, or 270~560 depending on the product grade.
