MJ13330 NPN silicon power transistor (NOS)

The MJ13330 is an NPN silicon power transistor manufactured by Motorola (and other companies). It's designed for high-voltage, high-speed power switching applications.
Key Features and Specifications
* Type: NPN Silicon Power Transistor
* Manufacturer: Originally Motorola, now also produced by other companies like Inchange Semiconductor.
* Applications: It's well-suited for high-frequency applications like switching regulators, inverters, motor controls, and relay drivers. Its high switching speed and durability make it ideal for these uses.
* Key Ratings:
* Collector-Emitter Sustaining Voltage (V_{CEO(SUS)}): 200V (minimum)
* Continuous Collector Current (I_C): 15A
* Power Dissipation (P_D): 175W at a case temperature of 25°C
* High-Speed Switching: It has a fast turn-off time, which is critical for efficient operation in switching circuits.
Physical Characteristics
The MJ13330 is typically found in a TO-3 package , a metal can with two large terminals and two mounting holes. This package is designed to dissipate a significant amount of heat, which is essential for a power transistor.
The transistor shown in your previous image with the part number "M11330" is likely a misread of the MJ13330 due to the vintage manufacturing process, as M11330 is not a recognized semiconductor part number from Motorola. The TO-3 package and the "M" logo with two peaks are consistent with Motorola's power transistors from that era.
