SMP1334-084LF

100 W High-Power Silicon PIN Diode

The SMP1334-084LF is a surface-mountable, low-capacitance silicon PIN diode designed as a series-connected PIN diode for high-power, high-volume switch and attenuator applications from 10 MHz to beyond 6 GHz.

Typical resistance at 100 mA is 0.45 Ω and maximum capacitance at 30 V is 0.45 pF. The combination of low capacitance, low parasitic inductance, and nominal 50 μm I-region width, makes the SMP1334-084LF useful in large signal switches and attenuator applications.

The device has a 1 W dissipation power rating, which makes it capable of handling up to 100 W @ 25 °C Continuous Wave (CW) in a series-connected transmit/receive (T/R) switch.

Design information for high power switches may be found in the Skyworks Application Note, Design With PIN Diodes (document number 200312).
