APD0505-000

RF Diode Overview

The APD0505-000 is a silicon PIN diode bondable chip from the Skyworks APD series, designed for high-performance RF and microwave circuits. It operates as a switch or attenuator across frequencies below 100 MHz to beyond 30 GHz. Key electrical specifications include a junction capacitance of 0.05 pF at 50 V reverse bias (1 MHz), a series resistance of 2.5 Ω at 500 MHz with 10 mA forward current, and a forward voltage of 0.93 V at 10 mA. The device features a 50 V reverse voltage rating, a 5 μm I-region thickness, and a thermal resistance of 118 °C/W. It has a top contact diameter of 1.50 mils and supports an operating temperature range of -65 °C to +175 °C.

RF Diode Procurement Notes

Verify component authenticity through authorized Skyworks distributors or direct channels. Confirm RoHS compliance status via the official Certificate of Conformance. Ensure proper ESD handling precautions are implemented during storage and assembly, as the device is sensitive to electrostatic discharge. Review the latest datasheet revision for any updates to absolute maximum ratings or electrical specifications before finalizing procurement orders.

RF Diode Selection Notes

Select the APD0505-000 for switching applications prioritizing minimal junction capacitance and low forward voltage. Compare its 0.05 pF capacitance against higher-capacitance variants like the APD0510-000 if lower loss is critical. Consider the 2.5 Ω series resistance and 118 °C/W thermal resistance when designing heat dissipation paths. Ensure the 50 V reverse voltage rating meets the circuit's peak reverse bias requirements.

RF Diode Part Context

The APD0505-000 belongs to the Skyworks APD Series of silicon PIN diode bondable chips. This series includes various models optimized for different switching and attenuator needs, ranging from low capacitance devices to high-power variants like the APD2220-000. All parts share common manufacturing processes but differ in I-region thickness, voltage ratings, and physical dimensions to suit specific RF performance criteria.

RF Diode Replacement Considerations

Direct replacements within the APD series include APD0510-000 and APD0520-000, which offer similar voltage ratings but higher capacitance and lower series resistance. For attenuator applications requiring higher power handling, the APD2220-000 is an alternative despite larger dimensions. Verify die drawing compatibility (150-806) and bonding methods when substituting.
