MA47266-146

RF Diode Overview

The MA47266-146 is a multi-purpose axial leaded glass PIN diode manufactured by MACOM Technology Solutions. It features a hermetically sealed ODS 146 package designed for moderate power applications requiring low package inductance. The device operates effectively from HF through S-Band frequencies, up to 2 GHz. Key electrical specifications include a reverse voltage of 200 VDC (measured at <10 µA leakage), a maximum capacitance of 1.50 pF at -50 V and 1 MHz, and a maximum series resistance of 0.6 Ω at 100 MHz with 10 mA forward current. It has a nominal carrier lifetime of 4.0 µs and an intrinsic region thickness of 3.0 mils.

RF Diode Feature Summary

• Hermetically sealed glass package construction provides inherent ruggedness suitable for harsh commercial and military environments.
• Designed for large signal switching applications with passivated chips to ensure low leakage current.
• Available in tape and reel packaging options for automated assembly processes.
• Capable of operation across a wide temperature range from -55°C to +175°C.

RF Diode Applications

• Switches
• Duplexers
• Electrically tuned digital filters
• AGC attenuators
• TR switches and RF modulators

RF Diode Procurement Notes

Verify the specific ordering suffix when purchasing, as standard bulk quantities may differ from tape and reel configurations. Confirm MIL-STD-19500 screening requirements if applicable to the mission profile. Check for RoHS compliance status against current regulatory directives. Ensure the component meets the absolute maximum ratings for the intended operating environment before integration.

RF Diode Selection Notes

Select the MA47266-146 for moderate power applications where low package inductance is critical. This ODS 146 style is distinct from lower capacitance variants like the ODS 54, making it better suited for higher power handling rather than ultra-low capacitance VHF series switches. Evaluate the 4.0 µs carrier lifetime against distortion requirements in attenuator circuits.

RF Diode Part Context

This component belongs to MACOM's Axial Leaded Glass PIN Diode series, which includes ODS 4, 54, 139, and 146 package styles. The ODS 146 package is specifically optimized for moderate power applications compared to the low-power ODS 54 or the high-power ODS 4. These devices are silicon PIN diodes known for their reliability in demanding RF environments.
