TSZ121ICT from STMicroelectronics, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Non-inverting input of the operational amplifier, part of the rail-to-rail input stage with common mode range extended to (VCC-)-0.1V to (VCC+)+0.1V. |
| 2 | VCC- | power_in | Negative supply rail (ground in single-supply operation); supply voltage range is 1.8 V to 5.5 V between VCC+ and VCC-. |
| 3 | IN- | input | Inverting input of the operational amplifier, part of the rail-to-rail input stage with common mode range extended to (VCC-)-0.1V to (VCC+)+0.1V. |
| 4 | OUT | output | Rail-to-rail amplifier output, capable of swinging to within 30 mV (typ.) of either supply rail when loaded with 10 kOhm to VCC/2. |
| 5 | VCC+ | power_in | Positive supply pin; operating supply voltage range is 1.8 V to 5.5 V, with maximum supply voltage of 6 V (absolute maximum). |
