MJ802 Frequently Asked Questions (FAQ)
-
The recommended operating voltage range for the MJ802 is 4.5V to 18V, with a typical voltage of 12V.
-
To ensure proper biasing, connect the base of the transistor to a voltage divider network that provides a stable voltage reference, and ensure the collector-emitter voltage is within the recommended range.
-
The maximum collector current rating for the MJ802 is 10A, but it's recommended to derate the current to 5A or less for reliable operation.
-
To prevent overheating, ensure proper heat sinking, use a heat sink with a thermal resistance of 1°C/W or less, and maintain a maximum junction temperature of 150°C.
-
While the MJ802 can be used as a switch, it's not recommended for high-frequency applications due to its relatively slow switching times (tf ≈ 10μs, tr ≈ 20μs). Consider using a faster-switching transistor or a dedicated high-frequency switch.
