OPA551FAKTWT

Texas Instruments · Operational Amplifier · TO-263-7

OPA551FAKTWT from Texas Instruments, in a TO-263-7. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	+IN	input	Noninverting input; the input voltage range is (V-) - 0.5 V to (V+) + 0.5 V per the Absolute Maximum Ratings.
2	-IN	input	Inverting input; the input voltage range is (V-) - 0.5 V to (V+) + 0.5 V per the Absolute Maximum Ratings.
3	NC	unconnected	No internal connection; can be left floating.
4	V-	power_in	Negative (lowest) power supply; total supply VS = (V+) to (V-) is 8 V to 60 V (±4 V to ±30 V) per the Recommended Operating Conditions.
5	V+	power_in	Positive (highest) power supply; total supply VS = (V+) to (V-) is 8 V to 60 V (±4 V to ±30 V) per the Recommended Operating Conditions.
6	Out	output	Amplifier output; safe output current is limited by the SOA curves, and the device supplies 200 mA continuous output current.
7	Flag	output	Thermal shutdown indicator that provides a current output to alert the user when thermal shutdown has occurred.
8	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

Symbol: OPA551FAKTWT
Footprint: Package_TO_SOT_SMD:TO-263-7_TabPin8
3D model: TO-263-7 (KiCad packages3D, STEP)
3D model files: opa551faktwt-etched.step / opa551faktwt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa551faktwt.step / opa551faktwt.glb are the bare package body.
