QJxx30LH4 series

Product catalog summary
Overview: The QJxx30LH4 series is a 30 Amp high-temperature Alternistor TRIAC designed for AC power control applications. It features a maximum junction temperature of 150°C and a surge capability of 350A at 60Hz, making it suitable for heater control, motor speed control, lighting controls, and static switching relays.
Main Features:
  • RMS on-state current: 30A
  • Voltage capability: 600V or 800V
  • High TJ of 150°C
  • Surge capability: 350A at 60Hz
  • Electrically isolated for 2500Vrms
  • UL Recognized and RoHS compliant
Applications: The TRIAC is ideal for use in heating, lighting, and motor speed controls, including applications like coffee brewers, tankless water heaters, infrared heaters, AC solid-state relays, light dimmers, and motor speed control in various appliances.
Absolute Maximum Ratings:
  • Peak non-repetitive blocking voltage: VDRM+200V
  • RMS on-state current: 30A at TC = 105°C
  • Non-repetitive surge peak on-state current: 350A at 60Hz
  • Storage temperature range: -40 to 150°C
  • Operating junction temperature range: -40 to 150°C
Electrical Characteristics: The TRIAC operates in quadrants I, II, and III, with a maximum gate trigger current of 35mA and a maximum gate trigger voltage of 1.0V.
Thermal and Mechanical Specifications: The device is housed in a TO-220 isolated package, providing robust mechanical and thermal performance. It features a junction-to-case thermal resistance of 3.2°C/W.
Environmental and Physical Specifications: The TRIAC meets various MIL-STD and JEDEC standards for temperature cycling, humidity, and solder heat resistance. It is constructed with a UL Recognized compound and 100% matte tin-plated terminals.
Design Considerations: To ensure longevity, it is recommended to limit the continuous current to 75% of the component rating and to use proper heat sinking and voltage ratings. Overheating, overvoltage, and surge currents should be avoided.
Dimensions: The TRIAC's dimensions are provided in both inches and millimeters, with specific tolerances for each measurement.
Part Numbering and Marking: The part numbering system includes information on voltage rating, current rating, sensitivity, package type, and lead form dimensions. The marking system includes a date code for traceability.
