Brand: Siemens.
Item: BUZ18 N-channel enhancement-mode power MOSFET transistor in a chassis-mount package.
Package markings include BUZ18, gate and drain designators G and D, a stylized Siemens logo, and the code 8524 on the top face.
Configuration is a single N-channel MOSFET device with three terminals and a metal mounting base designed for attachment to a chassis or heatsink.
Design features a black encapsulated body, two flat blade terminals emerging from the top surface, and a third blade terminal integrated with the metal base plate for mechanical support and heat dissipation.
Suitable for use in power switching, motor control, or general-purpose high-current DC applications requiring a chassis-mount BUZ18 MOSFET power transistor.
Condition: Pulled from prior equipment with handling wear visible on the metal base and terminals. Base plate shows scratches, discoloration, and marks from previous mounting; black encapsulation has small scuffs and residue around the potting area. Sold loose without original packaging; device is untested and offered as a single BUZ18 MOSFET for repair, replacement, or parts use.
