Timothy J. ★★★★★

The clamping diodes are a lifesaver for driving small solenoids and relays without worrying about back EMF frying my microcontroller. Worked perfectly in my test jig right out of the package.

Henry ★★★★★

Each channel handles up to 500mA and the DIP package is easy to solder onto a perfboard. I used them to drive some small relays from a 5V microcontroller and they work flawlessly.

Ruby B. ★★★★★

The built-in clamp diodes save me the trouble of adding separate protection for my inductive loads. Each darlington pair handles the current without issue, and having five in the pack means I've got spares for future projects.
