概述

Description

Introduction to MJL21194
- Type: A high-power silicon NPN transistor from Motorola’s MJL family (now produced by others).
- Use: Commonly used as a power output device in high‑power audio amplifiers (Class AB) and other high‑voltage/high‑current switch/regulator circuits. Often paired with its complementary MJL21193 (PNP) in push‑pull stages.
- Features: Rugged device designed for linear operation with adequate heat sinking; exact voltage/current ratings vary by revision and lot. Requires proper base drive and protection (biasing, thermal management, emitter resistors where appropriate).
- Packaging: Provided in power packages suitable for heatsinking (check the datasheet for exact package options).
- Notes: The MJL21194 family is older technology; for precise specs (Vceo, Ic, hFE, SOA), consult the specific datasheet. May be used in vintage gear and some modern retrofits; alternatives exist for current production needs.

Features

MJL21194 – quick features:
- PNP power transistor (complement to MJL21193)
- High-voltage, high-current device for audio output stages
- Suitable for push-pull, class-AB audio amplifiers
- Packaging: rugged TO-3/metal can style with isolated base for excellent heat sinking
- Matched with MJL21193 for complementary symmetry
- Wide safe-operating-area and good thermal stability
- Designed for linear audio applications with stable performance and relatively low distortion
- Requires proper heatsinking and biasing network in use
Note: For exact electrical ratings (Vceo, Ic, Pdiss, hFE, SOA), refer to the official datasheet.

Package

MJL21194 comes in a TO-3P metal-cased power package (high-voltage complementary transistor; PNP).

Pinout

- Pin count: 3 pins
- Function: High-power transistor (complementary pair with MJL21193) used for high-voltage/current amplification and switching. Terminals: base, collector, and emitter; in many packages the collector is tied to the case/heatsink.
