Component gives laser diodes reliable protection from electrostatic discharge

Pangolin Laser Systems has introduced what it calls the world's first electronic component to protect laser diodes against damage from direct and indirect electrostatic discharge (ESD). Called LASORB, the component is described as an "ESD absorber" that protects laser diodes, photodiodes, and LEDs from single, multiple, and repeated ESD events of either positive or negative polarity.

The component has applications across a wide array of consumer, commercial, and industrial products. LASORB also protects against reverse bias conditions. While Schottky diodes are typically used for this purpose, using LASORB in their place offers protection against both ESD and reverse biasing. Pangolin is currently producing two series of LASORB, one optimized for red and infrared diodes and a second optimized for Blu-ray diodes. The component package is compact (8.9mm tall x 10.4mm long x 3.8mm thick) and mounts in a 2-pin, through-hole configuration; Pangolin can also design custom packages, and an SMT version will be offered as well.

Pangolin unveils first component giving laser diodes reliable protection from electrostatic discharge

New "LASORB(tm)" Protects Against ESD Events, Surges, And Reverse Bias; Applications in Telecom, Storage, Blu-ray Devices, Medical, and Other Areas

In a major breakthrough for the longevity of products employing laser diodes, Pangolin Laser Systems, the world's largest producer of laser display software and control hardware, has introduced what it calls the world's first electronic component to protect laser diodes against damage from direct and indirect electrostatic discharge (ESD). Called LASORB, the component is described as an "ESD absorber" that protects laser diodes, photodiodes and LEDs from single, multiple, and repeated ESD events of either positive or negative polarity.

"LASORB has applications across a wide array of consumer, commercial, and industrial products," said William Benner, president and chief technology officer of Pangolin. "ESD is a well-known problem for laser diodes, especially Blu-ray laser diodes and low-power single-mode red laser diodes," he said. "Without LASORB, a single modest ESD event can cause permanent damage, resulting in partial or complete diode failure. Laser diodes often fail long before the manufacturers' rated life expectancy, and ESD is the suspected cause of many malfunctions."

Benner said LASORB also protects against reverse bias conditions. While Schottky diodes are typically used for this purpose, Benner said using LASORB in their place offered protection against both ESD and reverse biasing.

Pangolin is currently producing two series of LASORB, one optimized for red and infrared diodes and a second optimized for Blu-ray diodes. The component package is compact (8.9mm tall x 10.4mm long x 3.8mm thick) and mounts in a 2-pin, through-hole configuration; Pangolin can also design custom packages, and an SMT version will be offered as well.

"LASORB is a game-changer with respect protecting lasers from ESD," stated Benner. "As far as we know and based on thorough research, there is nothing in the world like it. Previous so-called solutions for ESD all fail in some respect to protect laser diodes. They are either too slow to respond, ineffective in the required voltage range, or incapable of absorbing the energy of a voltage surge.

"LASORB protects against ESD as well as from power surges caused by turning equipment on and off. It protects against reverse bias. It is an effective, field-proven solution," he said.

Benner said LASORB has already gained customers in government, universities, and commercial companies in several countries and that it is being applied in fields of electronics, medicine, security, entertainment, and scientific research.

Web Videos Demonstrate Component's Performance
Pangolin has set up a specific website for LASORB (www.lasorb.com) offering detailed product information and datasheets, background on laser diodes and ESD, a review of the limitations of previous ESD solutions in laser diodes applications, and links to other resources. The company has produced two videos demonstrating the effects of ESD on laser diodes, including Blu-ray diodes, and the effectiveness of LASORB in protecting them. The videos can be seen on the LASORB website or on YouTube.
