Description
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 (typical). 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.
A block diagram of the CLA4611-085LF is shown in Figure 1. The
absolute maximum ratings of the CLA4611-085LF are provided in
Table 1. Electrical specifications are provided in Table 2.
Typical performance characteristics of the CLA4611-085LF are
provided in Table 3 and illustrated in Figure 4.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
