This beautiful SOT23 test adapter is designed to complement your DCA55 or your DCA75 (or any other semiconductor tester). It's extremely easy to use thanks to the special spring-loaded SOT23 socket assembly. Your SOT23 part is gently and securely held against gold plated sprung contacts with a carefully controlled contact force. The adapter is designed to look like a giant SOT23 part, so it's easy to visualise the pinout of the part inside when using the DCA55 or DCA75. The unit is supported on 4 non-slip feet which also serves to keep the unit slightly raised from your work surface allowing for easier connections using micro-hooks or croc clips. The large area gold plated pads are also great for multimeter prods.
