CLA4603-085LF

Surface Mount Limiter Diode

The CLA4603-085LF 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 0.4 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 1.5 μm I-region width, makes the CLA4603-085LF useful in large signal limiter applications. The threshold level is +9 dBm, nominal.

Features

    • Low-thermal resistance: 40 °C/W
    • Typical threshold level: +9 dBm
    • Low capacitance: 0.33 pF
    • Low profile, ultra-miniature QFN (3-pin, 2 x 2 mm) package (MSL1, 260 °C per JEDEC J-STD-020)
