Description

The MJL21194 is a high‑power silicon transistor used as the complementary PNP output device in push‑pull audio amplifiers (paired with the MJL21193, the NPN). Originating from Motorola and now supplied by On Semiconductor, these parts are designed for Class AB power stages and offer robust voltage/current handling with good switching characteristics. They typically come in metal can packages (TO‑3/TO‑3P) and require heatsinking for high power. Typical specs (varies by revision): high collector‑emitter voltage (Vceo) in the 120–180 V range, substantial collector current (several amperes up to ~10 A) and strong dI/dt capability. Important notes: ensure proper pairing and biasing with the MJL21193, verify exact ratings from the datasheet, and check current/voltage limits and availability since older devices may be discontinued or cross‑referenced to modern equivalents.

Equivalent

Equivalent products: The direct complementary device is MJL21193 (NPN). MJL21194 is the PNP transistor; there isn’t a universal exact cross‑reference across all manufacturers. For substitutes, match key specs (Vceo, Ic, Pd, hFE, package) and use distributor cross-references to find compatible high‑voltage, high‑current PNP transistors from other brands.

Features

MJL21194 features:
- High-voltage, high-current power transistor (PNP) designed for audio output stages; complementary pair with MJL21193 (NPN)
- Vceo up to around 260 V; capable of several amps of continuous collector current
- Matched with its complementary device for push-pull Class-AB operation
- Robust, rugged construction in a TO-3P metal-can package for excellent heat dissipation
- Suitable for linear power amplification and other high-power, high-reliability applications
- Designed for stable, low-distortion performance in audio output stages with good thermal tracking and bias stability

Pinout

- Pin count: 3 electrical connections (base, emitter, and collector). In the TO-3/TO-3P package, the collector is the metal case.
- Function: High-voltage, high-current NPN power transistor used as a power/output device in audio amplifiers and other high-current switching/linear applications.

Manufacturer

- Manufacturer: On Semiconductor (ON Semiconductor).
- Company type: An American multinational semiconductor company that designs, manufactures, and sells semiconductor components (discrete devices and ICs) for automotive, industrial, communications, consumer, and other markets.

Application

Applications of MJL21194:
- High‑power audio amplifiers (output stage in Hi‑Fi and professional sound systems)
- Pro/guitar amplifiers
- Linear power supplies and voltage regulator stages needing high current
- Industrial drive/control circuits (high‑current switches and regulators)
- Other high‑voltage, high‑current amplification tasks requiring rugged NPN power transistors
Note: MJL21194 is a high‑voltage, high‑current NPN power transistor often used in power‑amp output stages.

Package

MJL21194 is a high‑voltage NPN power transistor in a TO-3P power package (3 leads). In this package, the case acts as the collector, with base and emitter on the two pins.
