What is the pinout of the TIP120 transistor?

In the TO-220 package, pin 1 is Base, pin 2 is Collector, and pin 3 is Emitter. The TIP120 is an NPN Darlington transistor.

What are the key specifications of the IRLZ44N MOSFET?

The IRLZ44N has VDSS = 55V, RDS(on) = 0.022Ω, and ID = 47A, and comes in a TO-220AB package.

What type of transistor is the TIP120?

It is an NPN Darlington transistor; the internal circuit shows two transistors in a Darlington pair with internal resistors and a collector-emitter diode.

What are the terminals of the IRLZ44N?

The schematic symbol shows Gate (G), Drain (D), and Source (S), with an internal body diode between drain and source.

What package styles are these components in?

The TIP120 is shown in a TO-220 package and the IRLZ44N in a TO-220AB package.

This image is a side-by-side comparison reference of two common power semiconductor components, apparently saved for a Subaru tach-adapter / coil-on-plug conversion project. The left panel, sourced from www.componentsinfo.com, shows the TIP120 NPN Darlington transistor pinout in a TO-220 package: pin 1 is Base, pin 2 is Collector, and pin 3 is Emitter. It includes the internal circuit diagram showing the two-transistor Darlington configuration with internal base-emitter resistors and a collector-emitter diode, plus the schematic symbol with the same pin numbering. The right panel shows the IRLZ44N N-channel logic-level power MOSFET, with its schematic symbol (Gate, Drain, Source and internal body diode) and key specifications: drain-source voltage VDSS = 55V, on-resistance RDS(on) = 0.022Ω, and continuous drain current ID = 47A, in a TO-220AB package with the International Rectifier (IOR) logo. A reader can learn the correct pin identification for the TIP120, its Darlington internal structure, and the headline electrical ratings and package style of the IRLZ44N, allowing comparison of the two devices for switching applications such as tachometer signal drivers or ignition-related circuits.
