Littelfuse's new high-temperature Alternistor triac simplifies thermal management and suppresses high surges
Littelfuse, Inc., a global leader in circuit protection solutions, has recently introduced two new high-temperature Alternistor triacs to its thyristor product line. These new additions, the 16AQJxx16xHx series and the 25AQJxx25xHx series, are specifically designed for AC switching applications where thermal management is a challenge. With a maximum junction temperature of 150°C, these triacs offer improved performance in environments with limited or no heat dissipation.
The QJxx16xHx and QJxx25xHx series are ideal for applications that require handling high inrush currents, such as in heater and motor control systems. Their robust design ensures reliability in demanding industrial and consumer environments. The triacs feature mechanical and thermal stability, making them a preferred choice over traditional wire-wound packages.
These triacs come in various package types, including TO-220, TO-263 (D2-PAK), TO-218AC, and TO-218X, offering flexibility for different application needs. They are available in both isolated and non-isolated configurations, and can be purchased in tubular or cartridge formats, with 500 units per tube or 500 cartridges per order. Samples are also available through authorized Littelfuse distributors worldwide.
Applications for the QJxx16xHx and QJxx25xHx series include coffee machine heaters, instant water heaters, infrared heaters, AC solid-state relays, dimmers for incandescent and LED lighting, motor speed controls in kitchen appliances and power tools, and compressor motor control in light industrial settings.
According to Koichiro Yoshimoto, Business Development Manager at Littelfuse Semiconductor Business Unit, “These triacs operate efficiently at high temperatures, reducing thermal management challenges and improving system reliability. The sturdy clip-on connection design ensures excellent on-site performance.â€
Key advantages of the QJxx16xHx and QJxx25xHx series include:
- Maximum junction temperature of 150°C for enhanced thermal performance
- High AITSM ratings (200A/250A) for superior inrush current handling
- Stable TO-220/263 and TO-218 clip-on packages for better field reliability
- Internally isolated packages for improved thermal dissipation and higher insulation voltage
