Deﬁnition of GreenTM, document number
The SMPA1304-011LF plastic packaged, surface mountable,
low capacitance (0.3 pF) silicon PIN diode is designed for
attenuator applications from 5 MHz to beyond 2 GHz.
The thick 100 μm I region of this PIN diode makes this device very
attractive for use in low distortion attenuators in vehicle
The 1 μs typical carrier lifetime of this diode results in a
resistance of 20 Ω maximum at 1 mA and 7 Ω maximum at
Table 1 describes the SMPA1304-011LF package and marking.

LS = 1.5 nH
The Pb-free symbol or “LF” in the part number denotes a lead-free, RoHS-
compliant package unless otherwise noted as Green™. Tin/lead (Sn/Pb)
packaging is not recommended for new designs.
