Surface-Mount PIN Diodes
Source: Skyworks Solutions, Inc.
Skyworks Solutions, Inc. has introduced new PIN diodes in an industry standard 0402 packaging technology for handset, WLAN, CATV Satcom, land mobile radios, infrastructure, T/R and switching applications. These new PIN diodes provide designers with a small form factor, low-profile and low inductance, all in a plastic surface mount technology (SMT) package. Additional benefits include low capacitance, resistance and thermal impedance.
The SMP1321-040LF is a plastic packaged, surface mountable PIN diode designed for high volume switch applications from 10 MHz to beyond 2 GHz. The low capacitance of this diode (0.25 pF) combined with its low resistance (2.0 O maximum at 10 mA) make the SMP1321-040LF particularly well suited for highisolation, series-connected PIN diode switches in batteryoperated circuits.
The SMP1321-040LF is also available in a variety of plastic packages and configurations that include a low inductance (0.4 nH) SOT-23 (the SMP1321-007), a small footprint SC-79, and a miniature SC-70. The SMP1321-508 has been specifically designed for WLAN 802.11 a/b/g applications.

The SMP1340-040LF is a surface mountable PIN diode, excellent for use in switch applications from 10 MHz to more than 3 GHz.
Maximum resistance at 10 mA is 1.2 O and maximum capacitance at 5 V is 0.3 pF. The combination of low capacitance, low parasitic inductance, and nominal 15 µm I-region width, makes the SMP1340-040LF useful in fast, high isolation switch applications.
- Low total capacitance: 0.3 pF maximum @ 5 V
- Low-series resistance: 1.2 O maximum @ 10 mA
- Industry-standard 0402 footprint
- Package rated MSL1, 260 °C per JEDEC J-STD-020
