MSS39-148-B10B

RF Diode Overview

The MSS39-148-B10B is a P-Type Silicon Schottky diode from the MSS39 series, designed for microwave biased-detector applications up to 40 GHz. It features very low 1/f noise and utilizes an epitaxial substrate for superior performance. Key electrical specifications at TA = 25°C include a minimum breakdown voltage (VBR) of 3.5 V, typical forward voltage (VF) of 0.39 V, and maximum junction capacitance (CJ) of 0.12 pF. The device exhibits a thermal sensitivity of 5,000 mV/mW with a test signal level of -58 dBm. Absolute maximum ratings specify a reverse voltage of 1 V, forward current of 50 mA, and CW power dissipation of 100 mW.

RF Diode Procurement Notes

Verify the specific ordering suffix against official MACOM documentation to confirm package type and pinout compatibility. Ensure that the absolute maximum ratings, particularly the 1 V reverse voltage limit, align with the target circuit design requirements before procurement. Confirm RoHS compliance status through the manufacturer's latest product release notes.

RF Diode Selection Notes

Select this component when low 1/f noise is critical for detector performance above 10 GHz. Compare the 0.12 pF junction capacitance against higher frequency alternatives if operation exceeds 26 GHz. Evaluate the 3.5 V breakdown voltage against system transient conditions. Consider the B10B outline dimensions for PCB layout constraints relative to other MSS39 variants.

RF Diode Part Context

This part belongs to the MSS39-xxx-x Series of P-Type Silicon Schottky Diodes manufactured by MACOM Technology Solutions. The series includes various models differentiated by their electrical characteristics and physical outlines, such as C15, E25, H20, and B10B packages. These devices are engineered specifically for high-frequency detection tasks requiring minimal noise interference.

RF Diode Replacement Considerations

MSS39-146-B10B offers similar characteristics with lower junction capacitance (0.10 pF) and a higher maximum frequency of 26 GHz. MSS39-152-B10B provides higher capacitance (0.18 pF) but maintains the same frequency rating. Cross-reference datasheet parameters carefully to ensure functional equivalence in the specific application environment.
