Multicomp Pro MJE350 PNP Transistor, TO126 Package
Multicomp Pro MJE350 -300V PNP transistor for line-operated power supplies, regulators & industrial circuits. 500mA, 20W, TO126 package.
The Multicomp Pro MJE350 is a robust PNP (Positive-Negative-Positive) plastic medium-power transistor engineered for demanding line-operated applications. Its high-voltage capability makes it an excellent choice for series-pass and switching regulator circuits where PNP functionality is required.
Designed with reliability in mind, this transistor features a -300V collector-base voltage rating, ensuring stable performance in various power management scenarios. Its through-hole mounting design provides secure physical and electrical connections for prototype boards or permanent installations.
Key Specifications & Features
- High Voltage Rating: With a collector-emitter voltage maximum of 300V, it is suited for mains-connected circuits.
- Adequate Current Handling: Offers a continuous collector current of 500mA for power control tasks.
- Robust Power Dissipation: Capable of dissipating up to 20W of power, facilitating use in medium-power applications.
- Stable Gain: Provides a minimum DC current gain (hFE) of 30, ensuring predictable amplification.
- Wide Temperature Range: Can operate in environments up to a maximum junction temperature of 150°C.
Its primary use is in industrial and power management electronics, particularly within offline power supplies, low-power series regulators, and other line-operated systems. The TO126 package is a standard, readily mountable format that balances size and thermal performance.
