BT137X series
General description
Passivated triacs in a full pack plastic envelope, intended for use in applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance. Typical applications include motor control, industrial and domestic lighting, heating and static switching.
Features
- Very low start-up supply current; 50 uA typical
- Low operating supply current; 1.2 mA typical
- Accurate, internally-trimmed, fixed frequency oscillator (100 kHz). No external timing components needed
- Internal slope compensation. No external ramp components needed
- Built-in over-voltage and under-voltage detection
- High-speed over-current trip; 170 ns typical
- Over-voltage clamp on supply voltage (VDD )
- Internal divider regulates VDD to 12 V. No external divider needed
- Leading edge blanking of the current sense signal
- Control frequency modulated over a narrow band to reduce Electromagnetic Interference (EMI)
- High output drive capability; 150 ns typical rise and fall time into 2 nF load
- Wide bandwidth (10 MHz) error amplifier with external compensation pin and simple interface to optocoupler
- Accurate internal bandgap reference.
