The SMP1321 series of plastic packaged, surface mountable PIN diodes are designed for high volume switch applications from 10 MHz to beyond 2 GHz. The low capacitance of these diodes (0.25 pF) combined with its low resistance (2.0 Ω maximum at 10 mA) make the SMP1321 series particularly suited to high isolation series connected PIN diode switches in battery operated circuits. Available in a selection of plastic packages and in a variety of configurations including a low inductance (0.4 nH) SOT-23 (SMP1321-007), the small footprint SC-79 and the miniature SC-70.
The Alpha SMP1321 series consists of low capacitance plastic packaged PIN diodes designed for high volume switch applications from 10 MHz to beyond 2 GHz. These diodes feature a specified capacitance of 0.25 pF and a low resistance of 2.0 Ω maximum at 10 mA, making them suitable for high isolation series connected PIN diode switches in battery operated circuits.
