UK 7-pin laser diode test socket

A 7-pin laser diode test socket in the UK can be sourced from suppliers like Thorlabs, JC Cherry, Mouser, and Farnell, offering PCB-mounted, strain-relieved, and ESD-protected options compatible with standard laser diode packages.

Overview

A 7-pin laser diode test socket is designed to securely hold a laser diode for testing or integration into optical systems. These sockets often include features such as:

• Gold-plated BeCu contacts for reliable electrical connection and low contact resistance
• ESD protection via Schottky or Zener diodes to prevent damage to sensitive laser diodes
• Strain relief assemblies to protect leads from mechanical stress
• PCB mounting for easy integration with laser diode drivers or test circuits Thorlabs, for example, offers sockets compatible with Ø5.6 mm to Ø9 mm laser diode packages, mounted on small PCBs with built-in voltage protection, suitable for forward voltages up to 7.5 V . JC Cherry provides sockets for TO-style packages, which may include cable-equipped options for flexible testing . Mouser Electronics and Farnell UK stock a variety of laser diode sockets and accessories, allowing selection based on pin count, package type, and mounting style .

Selecting a 7-Pin Socket

When choosing a 7-pin socket, consider:

• Package compatibility: Ensure the socket matches the laser diode package (e.g., TO-5, TO-18, or custom 7-pin configurations)
• Voltage rating: Check the forward voltage of your diode and select a socket rated accordingly (e.g., SR9 for up to 3.3 V, SR9H for up to 7.5 V)
• Mounting type: PCB-mounted sockets are common for lab testing, while solder-tail or pass-through designs may suit permanent installations
• ESD and strain relief: Essential for protecting sensitive diodes during testing
