The B58944 is typically a PNP Power Transistor designed for high-current applications. In the world of power electronics, "B" series nomenclature usually points to PNP configurations, while "D" series points to NPN. These are frequently used in complementary pairs for push-pull amplifier stages. Key Technical Specifications
This is the most critical visual in any “hot” datasheet. The SOA graph plots current vs. voltage, with diagonal lines for time and thermal limits. nec b58944 datasheet hot
