Additional Details

The BT151X-500C comes in a SOT82 package. It features a repetitive peak off-state voltage of 500V and an on-state RMS current of 7.5A. The gate trigger current is very low which allows it to be driven directly by microcontrollers or other low power signal sources. Its surge current capability is specified to withstand non-repetitive surge currents.

This thyristor is typically used where precise control and high voltage/current handling are required. The sensitive gate makes it particularly useful in applications where direct logic-level triggering is needed. Its robust design ensures reliable operation even under harsh electrical conditions.
