are any updates.
Shipping Cost
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The
basic freight (for package ≤0.5kg or corresponding volume) depends on the time zone and
country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:
FedEx International, 5-7 business days.

PD638B Overview
Bulk is used to protect the photodiodes from damage. Photodiodes are protected by Radial packages in order to ensure their safety. Continuous reverse-bias means the photodiodes can withstand only 170V voltage. It is recommended to set the reverse-bias mode for the photodiodes to not exceed 170V on a continuous basis. A photodiode has a pin number of 2. The current in a photodiode is 5nA even when there is no light input.
