About this product
MPSA06 is an NPN Darlington transistor in a TO-92 plastic package with very high current gain. It is used for switching small loads such as relays, LEDs, and lamps, and for interfacing low-current logic signals to higher-power circuits. It is the 80 V version of the MPSA05 family.

Frequently asked questions
Can I drive MPSA06 directly from an Arduino or ESP32 pin?
Yes for small loads, since the Darlington gain is very high. Use a series base resistor, typically a few kilo-ohms, so the base current stays low. Add a flyback diode across inductive loads like relays.
What is the difference between MPSA06 and MPSA05?
Both are NPN Darlington transistors in TO-92 rated for 500 mA. MPSA06 has an 80 V collector-emitter rating, while MPSA05 is rated at 60 V, so choose MPSA06 when the circuit voltage is above 60 V.
