    Ive been building a laser module for a while, but due to the sensetivities of these diodes, I was wondering if putting TVS across it's leads will help absorve spike/transients.
    they are far more faster then zener diodes, and will absorb those spikes, but im unsure if they are enough to stop a spike before it will damage the laser diode.
    the TVS I had in mind is a bipolar diode, and has a clamping voltage of 5V, and I am operating the laser at 4.2V, so mostly wanted to use this TVS to help against static or some freak transient that could come from the driver.

    Has anyone else here used TVS for a laser diode? (can diode, 5.6MM)
    the diode bieng used is a 445nM diode, running at ~1000mW
