TLP321-2BLSMT&R,

Transistor, Photovoltaic Output Optoisolators Overview

The TLP321-2BLSMT&R is a dual-channel surface-mount optocoupler manufactured by Isocom Components. It features an infrared LED input paired with two phototransistor outputs, housed in an 8-pin SMD package. The device provides high isolation voltage of 5300Vrms between input and output circuits. Maximum forward current for the input LED is specified at 50mA. The collector-emitter breakdown voltage (V(br)ceo) is rated at 80V. This component is designed for applications requiring electrical isolation and signal transmission in compact surface-mount layouts.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when ordering. Confirm that the 'SM' designation aligns with required surface-mount footprint specifications. Check for VDE approval requirements, which may necessitate adding an 'X' to the part number. Ensure compatibility with existing PCB silkscreen and solder mask designs before finalizing procurement quantities.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component where dual-channel isolation is necessary within a single package. Consider the 80V collector-emitter voltage limit for switching low-voltage signals. Evaluate the 5300Vrms isolation capability against system safety standards. Compare physical dimensions against available board space constraints. Verify input current requirements do not exceed the 50mA maximum rating.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to Isocom's line of photocouplers, specifically designed as alternatives to standard commercial optocouplers. The TLP321 series utilizes transistor outputs for general-purpose switching. Isocom components are often used to replace obsolete parts from other manufacturers.
