DATA SHEET CLA4603-085LF: Surface Mount Limiter Diode Applications Anode Anode (Pin 3) (Pin 1) Low-loss, high-power limiters Receiver protectors Features Cathode Low thermal resistance: 96 C/W (Pin 2, Exposed Paddle) Typical threshold level: +9 dBm Figure 1. CLA4603-085LF Block Diagram 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) Description The CLA4603-085LF is a surface mountable, low capacitance Skyworks Green products are compliant with silicon PIN limiter diode designed as a shunt connected PIN diode all applicable legislation and are halogen-free. for high power limiter applications from 10 MHz to over 6 GHz. For additional information, refer to Skyworks Maximum resistance at 10 mA is 2 and maximum capacitance Denition of Green, document number at 6 V is 0.4 pF. The combination of low junction capacitance, low SQ04-0074. parasitic inductance, low thermal resistance, and nominal 1.5 m I-region width, makes the CLA4603-085LF useful in large signal limiter applications. The threshold level is +9 dBm, nominal. A block diagram of the CLA4603-085LF is shown in Figure 1. The absolute maximum ratings of the CLA4603-085LF are provided in Table 1. Electrical specifications are provided in Table 2. Typical performance characteristics of the CLA4603-085LF are provided in Table 3 and illustrated in Figures 4 and 5. Skyworks Solutions, Inc.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
