The NEC B58944 (uPC58944) is a 60V, 30A N-Channel Power MOSFET in a TO-3P package. It is a legacy part often found in older power supplies and motor control circuits. "Hot" in the search query likely refers to its historical popularity as a service part or its physical temperature during operation. Look for cross-reference parts if exact replacement is unavailable, ensuring $V_DSS$, $I_D$, and $R_DS(on)$ specifications meet or exceed the original.
A: That is the absolute maximum. Running continuously at 175°C will seriously reduce the component’s lifetime (by years or months). Design for Tj < 125°C for reliability. nec b58944 datasheet hot
, here is a breakdown of its "best" feature and core technical highlights: The NEC B58944 (uPC58944) is a 60V, 30A
The (often associated with the marking D43256BGU-70Y ) is a specialized integrated circuit frequently found in automotive engine control units (ECUs), particularly those manufactured by Bosch . In the context of "hot" or overheating components, this chip is known as a high-failure part that often requires replacement during ECU repairs. Component Overview Look for cross-reference parts if exact replacement is
High voltage rating for audio stability.
Replacing a faulty B58944 can restore functionality to a "dead" ECU without needing to re-program the entire unit, provided the main flash memory remains intact.
