Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BLSMT&R' against official Isocom documentation to confirm it denotes the tape and reel packaging format and any specific binning or electrical selection criteria. Ensure the ordering code matches the exact surface mount package variant required for your PCB layout. Cross-reference the datasheet revision date to ensure compliance with current RoHS and UL/VDE standards.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-density surface mount installation is required alongside standard phototransistor output characteristics. Consider the 5300Vrms isolation rating for safety-critical interfaces. Evaluate the 50% minimum CTR for logic level compatibility. Confirm that the surface mount footprint aligns with the available land pattern in the design library before finalizing the part number.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP621/ISP621 series of high-density mounting phototransistor optically coupled isolators. The series typically includes single, dual, and quad channel variants in DIP and surface mount packages. The 'ISP' prefix indicates Isocom's manufacturing line, while the 'SM' or 'SMT&R' suffixes denote surface mount and tape/reel configurations respectively.
