Video reconstruction filter in a TSOT-23-5
140 mA output — what it buys you
The 140 mA output current rating is the headline number for this part. In a reconstruction filter, that current drives the feedback network and the cable termination simultaneously — typically 75 Ω for standard-definition video. With 140 mA on tap, you have enough headroom to drive a double-terminated line (150 Ω load) without clipping, and still keep the amplifier in its linear region. The 8 mA supply current is the quiescent cost for that capability; it is not a low-power video amp, but it is reasonable for a dedicated filter stage that is always on.
The TSOT-23-5 is a thin SOT-23 variant — 5 pins, about 2.9 mm by 1.6 mm. It is a surface-mount part, so reflow soldering is the expected assembly method. No dual-supply option here — it is single-supply only, so the input and output must be biased appropriately for the video signal's DC level.
The 'Bulk' shipping medium means it arrives in tubes or trays — not tape-and-reel — so factor that into your pick-and-place setup if you are ordering volume.
