Q4015LTTP
双向可控硅 400V 15A 33/43V
Description Q4015LTTP
The Quadrac is an internally triggered Triac designed for AC switching and phase control applications. It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components.
Standard type devices normally operate in Quadrants I & III triggered from AC line.
Alternistor type Quadracs are used in circuits requiring high dv/dt capability.
Features & Benefits Q4015LTTP
• RoHS Compliant
• Glass – passivated junctions
• Voltage capability up to 600 V
• Surge capability up to 200 A
Applications Q4015LTTP
Excellent for AC switching and phase control applications such as lighting and heating. Typical applications are AC solid-state switches, light dimmers, power tools, home/ brown goods and white goods appliances.
Alternistor Quadracs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance.
Internally constructed isolated package is offered for ease of heat sinking with highest isolation voltage.
Design Considerations
Careful selection of the correct device for the application’s operating parameters and environment will go a long way toward extending the operating life of the Thyristor. Good design practice should limit the maximum continuous current through the main terminals to 75% of the device rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage.
