CLA4611-085LF

Surface Mount Limiter Diode

The CLA4611-085LF is a surface mountable, low capacitance silicon PIN limiter diode designed as a shunt connected PIN diode for high power limiter applications from 10 MHz to over 6 GHz.

Maximum resistance at 10 mA is 1.2 Ω and maximum capacitance at 38 V is 0.25 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 12 μm I-region width, makes the CLA4611-085LF useful in large signal limiter applications. The threshold level is +25 dBm, nominal.
