------Question for MTPD2601SL-100 Please Put your question below------
Hi,
I have bought couple of MTPD2601SL-100 and MTPD2601T-030 I would like to know the bias voltage under which the 1.24 A/W Responsivity has been measured. Is it for 0V or -1V?
Welcome to DigiKey’s TechForum,
Spectral Responsivity is not constant and changes with wavelength of light. the A/W rating given is under the condition as noted λ=2400nm. Relative Responsivity is graphed on their datasheet. Intended to be used with a reverse bias voltage the datasheet specifies 1V.
Hi k.t.tersis,
From here on the Marktech website, it states the following:
PIN Photodiode
A photodiode with a wide, undoped intrinsic region sandwiched between heavily doped p+ and n+ regions. These are built to be used with a reverse bias voltage (photoconductive mode). Marktech’s position for silicon based devices is any photodiode built on N-type silicon with a resistivity greater than 400 ohm-cm is considered a PIN photodiode.
It does not specify at what reverse voltage they test with, but as most of the test conditions used in the datasheet specify 1V, I suspect that 1V is the bias voltage used in this case as well.
