Procurement Notes

Verify the specific ordering suffix when purchasing. The PBFREE designation indicates lead-free plating compliance. Requesting tin/lead plated devices requires adding the TIN/LEAD suffix to the part number. Confirm package type and marking code B6D match project requirements before finalizing orders.

Selection Notes

Select this component for designs necessitating a dual in-series arrangement in a compact SOT-323 footprint. Ensure the required reverse voltage does not exceed 300 V and that thermal management accommodates the 275 mW dissipation limit. Verify compatibility with the specified operating temperature range of -65 to +150 °C.
