Amk, sure they're overdriven when they're outputting 150mW, which is about 250mA, but most people get a good life out of them at that current. Of course the phazer diodes are better since they're rated at more than twice the mW than the senkat diodes, but it looks like you can't push them a lot over spec, the senkat diodes can be pushed twice over spec, but daedal said his phazer died when he pushed it to 323mW.
And the new senkat diode batch are rated at 100mW cw, but 180mW pulsed as oposed to 80mW cw and 250mW pulsed of the good batch.
Check out some of the responses after daedal posted the graph here:
