Ushio launches longer-life, 405 nm, 600 mW electrostatic-resistant laser diodes
HL40173MG and HL40175MG both feature a Zener diode as a safeguard against electrostatic discharge (ESD). The inclusion of the Zener means the 600 mW laser diodes gain a built-in resistance to ESD, over-voltage, and reverse voltage, thereby making the products easier for customers to handle.
