Product Description
The BT138-600E is a high-performance TRIAC,designed for AC switching and phase control applications.It features a 600V blocking voltage and a 12A current rating, making it ideal for power control in industrial and consumer electronics. With high surge current tolerance, low gate trigger requirements, and reliable performance, the BT138-600E is widely used in motor controls, lighting dimmers, heating systems, and solid-state relays.
Mechanical Data
- Current Rating: 12A (RMS)
- Voltage Rating: 600V (repetitive peak off-state voltage)
- Gate Trigger Current (I_GT):10mA (typical)
- On-State Voltage Drop (V_T): 1.6V (at 15A)
- Package: TO-220C
Features&Advantages
- High Voltage Capability – Supports up to 600V repetitive peak off-state voltage
- Moderate On-State Current – Rated for 12A RMS on-state current
- Low Gate Triggering Requirements – Can be triggered with a relatively low gate current, simplifying control circuit design.
- Sensitive Gate Triggering – Supports gate triggering in all four quadrants, enhancing triggering flexibility.
- TO-220 Package – Standard TO-220 form factor for easy heatsinking and PCB mounting.
Typical Applications
- Dimmer circuits (for incandescent/LED lighting)
- AC motor speed control
- Solid-state relays (SSRs)
- Heating control systems
- Power tools and appliances
