About this product
BC517 Darlington transistor rated at 30V and 1A in a TO-92 package. The Darlington pair gives very high current gain, so a small base current can switch or drive heavier loads such as relay coils, LED arrays and small motors. Check the datasheet for pin order and polarity before wiring, since the TO-92 pinout varies between manufacturers.

Can I drive a relay directly with this transistor?
Yes, if the relay coil voltage stays within 30V and its current stays within the 1A rating. For inductive loads such as relay coils, add a flyback diode across the coil to protect the transistor from voltage spikes.
Which pin is base, collector and emitter?
The pin order for TO-92 packages differs between manufacturers, so do not assume it. Confirm the base, collector and emitter pins from the datasheet of the specific part you received before wiring the circuit.
