What happens if the photodiode is forward biased by mistake?
Photodiodes when forward biased (positive voltage on Anode) with biases over 0.7V, they will conduct a substantial amount of current. If the current exceeds a specific threshold level or if the conduction time exceeds a specified amount, the device may be permanently damaged. In the assembled form, the Aluminum bonding wire will get burnt-off if the forward current reaches over 100 mA.
