ROHM 2SA1037AK 2SA1576A 2SA1774 Data Sheet

Summary

These technical specifications are essential documentation for a range of general-purpose NPN bipolar junction transistors (BJTs), including models such as 2SA1037AK, 2SA1576A, and 2SA1774. Engineered for circuit designers and electronics developers, this manual provides comprehensive data critical for reliable component selection. It details absolute maximum ratings, in-depth electrical characteristics (such as $h_{FE}$, transition frequency ($f_T$), and breakdown voltages), various packaging types (SMD/EIAJ), and detailed application curves needed to optimize transistor performance in sophisticated electronic circuits.

Frequently Asked Questions

What is the absolute maximum junction temperature for these components?

The Junction temperature ($T_j$) must not exceed 150°C.

What are the limits for the Collector-base voltage (V_cbo)?

The absolute maximum rating for collector-base voltage ($V_{CBO}$) is −60 V.

How can I determine the expected current gain ($h_{FE}$)?

The DC current transfer ratio ($h_{FE}$) varies and is specified in ranges, typically from 120 to 560.
