Device Structure

Single NPN BJT structure in a TO-220 package. The three pins correspond to base, collector, and emitter. Designed for efficient heat dissipation and compatibility with common heatsinks. Pin connections are standardized for TO-220.

Performance Characteristics

Supports fast switching with a transition frequency of up to 50MHz. Robust power handling up to 83W, making it suitable for high-current applications. Low Vce(sat) reduces power loss and improves efficiency. Stable current gain across rated conditions ensures reliable operation with predictable amplification behavior.

Application Environments

Used in power amplifiers, high-speed switching circuits, power supplies, inverters, and motor control. Suitable for both industrial and consumer electronics. Performs well in demanding environments requiring high current and fast switching, such as automotive, communication base stations, and home appliances.

Selection Guidelines

Choose if your application demands high current (up to 15A), moderate voltage (up to 80V), and efficient switching. Suitable where thermal management with TO-220 and board-mount design are needed. Ideal for users seeking RoHS and REACH compliance. Verify compatibility with control voltages/currents in your circuit, and check driver stage capability to supply adequate base current.

Usage Considerations

Ensure adequate heatsinking due to high-power capability. Keep Vce and Ic below absolute maximums for safe operation. Confirm pinout before installation. Protect against voltage spikes and inductive loads with appropriate snubbing or clamping circuits. Use in dry, ventilated enclosures to maintain operating temperature range. Follow antistatic precautions during handling.
