Overview
Description
Introduction to MJL21193
- What it is: A high-voltage, high-current NPN silicon power transistor from Motorola (MJL family), commonly used in audio power amplifiers and other power stages. Complementary device is MJL21194 (PNP).
- Typical use: Push‑pull Class AB output stages in high‑end audio amps; can also drive or switch power supplies and similar loads requiring rugged NPN power devices.
- Key attributes (qualitative): NPN transistor with a relatively high voltage rating and several amps of collector current; designed for substantial power dissipation and decent switching speed for a bipolar device.
- Design considerations: Requires proper base drive and a heatsink; bias stability is often enhanced with emitter resistors and thermal coupling to the heatsink; observe safe operating area under your conditions.
- Packaging: Available in robust power packages (various metal/TO‑style housings); verify package and exact ratings in the data sheet.
- Datasheet: Exact values for Vce, Ic, Pd, and hFE vary by lot and revision—consult Motorola/Onsemi data for precise specs. If you want, I can pull the current numbers.

Pinout
MJL21193 is a high-power NPN transistor in a TO-3/TO-3P style package. Pin count: 3 terminals (two leads plus the case). Lead functions: base (one lead), emitter (the other lead), collector (the case/metal body, usually mounted to a heatsink). Function: power output transistor; current flows from collector to emitter when base is driven positive relative to the emitter.
