Overview
The BTA08 and BTA16 are widely used triacs, both intended for AC switching applications. Below is a detailed comparison to help you determine which one best suits your application needs.
1.Current and Voltage Ratings
| Parameter | BTA08 | BTA16 |
|---|---|---|
| RMS Current | 8A | 16A |
| Non-Repetitive Surge Current | 80A | 160A |
| Voltage Rating | 600V/800V | 600V/800V |
BTA16 is better for high-power applications.
2.Triggering and Gate Characteristics
| Parameter | BTA08 | BTA16 |
|---|---|---|
| Gate Trigger Current | 25-50mA(typical) | 5-50mA(typical) |
| On-State Voltage Drop | ≤1.5V | ≤1.5V |
| Trigger Quadrants | 4-quadrant | 3-quadrant |
BTA08 is easier to drive with low-power circuits (e.g., microcontrollers).
3.Applications
BTA08: Light Dimmers, Small Motors, Heating Controls
BTA16:Industrial Motor Controls, Large Heaters, Solid-state Relays
4.Cost and Availability
- BTA08 is cheaper and widely used in consumer electronics.
- BTA16 costs slightly more but is necessary for high-current designs.
Conclusion
BTA08 and BTA16 both are 600V, 4-quadrant TRIACs, so the decision mainly depends on current requirements and thermal considerations.
