Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping format and package type. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the procurement channel provides valid traceability for the component batch.

Selection Notes

Select this component when a high-voltage small signal diode with low leakage is required in a compact footprint. Compare its 200 V rating and 4.0 pF capacitance against alternative switching diodes to ensure compatibility with circuit speed and voltage requirements.

Part Context

This part belongs to the MMBD150xA series of small signal diodes from onsemi. It shares the same SOT-23 package and core electrical architecture as variants like the MMBD1501A, MMBD1503A, and MMBD1504A, differing primarily in internal configuration or marking codes while maintaining similar high-voltage switching capabilities.
