CLA4607-108

RF Diode Overview

The CLA4607-108 is a silicon PIN diode designed for limiter applications, packaged in a hermetic ceramic surface-mount package measuring 1.83 x 1.43 x 1.0 mm. It features a reverse voltage rating of 120 V and an I-layer thickness of 7 µm. The device exhibits a typical capacitance of 0.27 pF at 1 mHz with 0 V reverse bias and a typical series resistance of 2.5 Ω at 100 mHz with 10 mA forward current. Its carrier lifetime is specified as 50 ns. The component operates within a temperature range of -55 °C to +150 °C and dissipates up to 250 mW at 25 °C.

RF Diode Feature Summary

• Hermetic ceramic packaging provides excellent reliability and low parasitic impedance for high-frequency operation.
• Optimized I-layer design delivers strong limiting action suitable for receiver protection circuits.
• Low thermal impedance supports stable performance under continuous power dissipation.

RF Diode Applications

• Limiter circuits
• Receiver protection

RF Diode Procurement Notes

Verify the specific datasheet revision and electrical parameters against the manufacturer's official documentation before integration. Confirm that the hermetic package dimensions and land pattern requirements align with the target PCB layout. Ensure ESD handling procedures are strictly followed during assembly to prevent damage to the sensitive semiconductor junction.

RF Diode Selection Notes

Select this component when robust receiver protection is required in harsh environments due to its hermetic sealing. The 120 V rating and 50 ns carrier lifetime distinguish it from lower-voltage switching variants. Verify that the 2.5 Ω series resistance meets the insertion loss constraints of the specific limiter topology being implemented.

RF Diode Part Context

This part belongs to the Skyworks CLA460x family of silicon PIN diodes housed in the -108 hermetic ceramic package. It is specifically categorized for limiter applications, distinct from the SMP13xx series which targets switching and attenuation functions. The family utilizes established silicon technology to ensure tight control over the I-layer base width for consistent performance.

RF Diode Replacement Considerations

The CLA4605-108 and CLA4608-108 are documented members of the same hermetic package family. Substitution requires verification of reverse voltage ratings and carrier lifetimes to ensure compatibility with the existing limiter circuit design.
