Triacs datasheet and documents for QJ6040KH7TP
Triacs Overview
The QJ6040KH7TP is a high-temperature triac manufactured by Littelfuse, designed for robust power control applications. It features an RMS on-state current of 40 A and a rated repetitive peak off-state voltage of 600 V. The device supports a non-repetitive peak on-state current of 500 A and maintains a low on-state voltage of 1.6 V. Gate triggering requirements include a maximum holding current of 100 mA, with gate trigger voltage and current specified at 1.3 V and 100 mA respectively. It operates within a temperature range of -40°C to +150°C and utilizes an SMTO-218 through-hole package.
Triacs Feature Summary
- High thermal stability enabling operation up to 150°C junction temperature
- High surge current capability of 500 A for robust circuit protection
- Low on-state voltage drop for improved energy efficiency
Triacs Applications
- Industrial motor speed control systems
- High-temperature heating element regulation
- Solid-state relay modules requiring elevated thermal ratings
Triacs Procurement Notes
Verify the specific suffix KH7TP against official Littelfuse documentation to confirm pinout and thermal characteristics. Ensure compatibility with existing heat sink designs due to the SMTO-218 package dimensions. Confirm availability through authorized distributors as lead times may vary based on production schedules.
Triacs Selection Notes
Select this component when applications demand higher thermal endurance than standard triacs provide. The 600V rating suits medium-voltage AC switching tasks. Compare the 500A surge capability against circuit fault conditions to ensure adequate safety margins during inrush events.
Triacs Part Context
This part belongs to the QJxx40xx series from Littelfuse, which specializes in high-temperature thyristor solutions. The series is engineered for environments where standard components might fail due to excessive heat, offering enhanced reliability for critical power electronics.
Triacs Replacement Considerations
Direct substitutes must match the 40A/600V rating and SMTO-218 package. Verify if alternative manufacturers offer equivalent high-temperature variants with compatible gate drive characteristics.
