CLA4605-085LF

Surface Mount Limiter Diode

The CLA4605-085LF 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 2 Ω and maximum capacitance at 6 V is 0.45 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 2 um I-region width, makes the CLA4605-085LF useful in large signal limiter applications. The threshold level is +9 dBm, nominal.
