MBD301

RF Diode Overview

The MBD301 is a silicon hot-carrier Schottky barrier diode manufactured by onsemi. Designed primarily for high-efficiency UHF and VHF detector applications, this single diode features a maximum repetitive peak reverse voltage of 30 volts and a power dissipation rating of 200 milliwatts. It utilizes a TO-92 package with two pins, making it suitable for low-cost, high-volume consumer and industrial requirements. The device is also adaptable to various fast-switching RF and digital applications.

RF Diode Procurement Notes

Verify the specific ordering suffix when purchasing, as variations such as MBD301G or MMBD301LT1G may exist with different packaging or compliance attributes. Confirm RoHS and halide-free status through official datasheets or compliance documents provided by onsemi before finalizing procurement decisions.

RF Diode Selection Notes

Select the MBD301 for applications requiring a cost-effective silicon Schottky diode in a through-hole TO-92 package. Ensure the 30-volt reverse voltage rating meets circuit requirements. Consider surface mount alternatives like the MMBD301LT1G if PCB space constraints necessitate a smaller footprint.

RF Diode Part Context

The MBD301 belongs to onsemi's family of silicon hot-carrier diodes, which includes variants like the MBD301G and surface-mount versions. These devices share similar electrical characteristics but differ in packaging and compliance markings. They are standard products within the onsemi discrete semiconductor portfolio.

RF Diode Replacement Considerations

Direct replacements include the MBD301G, which shares identical electrical specifications but may have updated compliance markings. Surface-mount equivalents such as the MMBD301LT1G offer the same performance in a compact package. Verify pin compatibility and thermal ratings when substituting.
