Intended for protecting op-amp, sample-and-hold and multiplexer inputs, Linear Systems has created a range of extremely low-leakage picoamp diodes (PADs) with reveres currents ranging from 1pA to 100pA, which are “pin-for-pin replacements for Siliconix-Vishay”, said Linear.
They are available in:
The leakage in pA (at 20V) is indicated by a number after the letters.
The lowest leakage versions only come in the TO-72 package and are PAD1 and PAD2, leaking 1 and 2pA respectively.
Apart from the DFNs, 5, 10, 20 and 50pA versions are available in all packages, then 100, 200 and 500pA versions are available in selected packages.
DFNs come only in 5 and 50pA versions.
They are available in:
- TO-92 two-lead (part name = JPAD, 35Vmax reverse)
- TO-72 (PAD, 45Vmax)
- SOT-23 (SSTPAD 30V)
- DFN eight-lead (PAD-DFN, 30Vmax)
