Applications
- General purpose switching circuits
- Signal demodulation
- Clamping and protection applications
Procurement Notes
Verify the specific ordering suffix 'ALT1G' corresponds to the required tape and reel packaging quantity of 3000 units. Confirm that the component meets RoHS compliance standards as indicated in the datasheet. Ensure the SOT-23 footprint matches the design layout requirements before finalizing procurement specifications.
Selection Notes
Select this component when a dual diode configuration is required in a minimal footprint. The 200 V rating provides sufficient margin for many low-voltage logic and signal processing interfaces. Consider the thermal resistance and power dissipation limits if operating near maximum current ratings or elevated ambient temperatures.
Part Context
This part belongs to the MMBD140x series of small signal diodes from onsemi. The series includes variants such as MMBD1401, MMBD1404, and MMBD1405, which share similar electrical characteristics but differ in internal connection configurations. These devices are designed for high-speed switching applications requiring low capacitance and fast recovery times.
Replacement Considerations
Direct replacements within the same family include MMBD1401, MMBD1404, and MMBD1405. Verify pinout compatibility as these variants may have different internal anode/cathode arrangements. Cross-reference with other manufacturers' SOT-23 dual diodes only if electrical parameters match exactly.
