BT151-800R product description

        The BT151-800R is a thyristor thyristor in a SOT78 plastic package for applications requiring high bi-directional blocking voltage capability, high surge current capability and high thermal cycling performance. The product has the following features and advantages:

        1. High bidirectional blocking voltage capability: The product's repetitive peak turn-off voltage (VDRM) and repetitive peak reverse voltage (VRRM) are both 800V, which can withstand high-voltage AC or DC power.

        2. High surge current capability: The non-repetitive peak on-state current (ITSM) of this product is 120A (10ms half sine wave) or 132A (8.3ms half sine wave), which can resist instantaneous large current impact.

        3. High thermal cycle performance: The junction temperature (Tj) range of this product is -40°C to +125°C, it can work stably in a wide temperature range, and has good heat dissipation performance.

BT151-800R product application

        1. Ignition circuit: BT151-800R can be used as an ignition device to generate high-voltage sparks to ignite gasoline or other combustibles.

        2. Motor control: BT151-800R can be used as a control device for AC or DC motors to realize functions such as starting, stopping, and speed adjustment of the motor.

        3. Protection circuit: BT151-800R can be used as a protection device for overvoltage, overcurrent, overtemperature and other faults, cut off abnormal power supply or load, and protect the safety of the circuit.

        4. Voltage adjustment: BT151-800R can be used as a voltage stabilizing device to adjust the size and waveform of the output voltage and provide a stable power supply.
