The PCO-7120 has been discontinued and is no longer available for order.

A replacement product is in development and will be available in the fall of 2017.

PCO-7120 50A Laser Diode Driver

PCO-7120 50A Laser Diode Driver


The PCO-7120 is a compact, economical OEM laser diode driver module designed to provide extremely fast, high current pulses. It offers variable output current from 500mA to 50A, with continuously variable pulse widths from 12ns to >1μs and pule repetition frequencies up to 1MHz.

Mounting pads on the PCO-7120 are provided to mount the laser diode directly to the driver, eliminating the need for interconnect cables or striplines. The four-hole mounting pattern accepts TO-18, TO- 5, TO-52, 5.6MM, and 9MM packages, as well as other packages of similar dimensions and lead spacing, mounted perpendicular to the driver circuit board. To facilitate different packages and mounting preferences, there are two solder pads on the end of the board to accept various laser diode packages mounted on axis to the driver. Furthermore, the diode can be connected remotely from the driver using a low-impedance stripline interconnection between the mounting pads and the leads of the laser diode.

A current monitor output may be viewed with an oscilloscope, providing a straight-forward means to observe the diode current waveform in real-time.

The PCO-7120 driver provides high-speed performance, variable pulse width, current and frequency, a robust design, flexible mounting configurations and the ability to drive a wide range of laser diodes in a small package. These features provide the user with an economical OEM module with the flexibility to be readily designed into a wide range of products.
