COSEMITECH · Magnetic Sensors · TO-92S
CH461ATB from COSEMITECH, in a TO-92S. 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 | VDD | power_in | Supply Voltage pin; the datasheet specifies a supply range of 3.5 V to 30 V with an absolute maximum supply voltage of 40 V. |
| 2 | GND | power_in | Ground pin for the TO-92S package (pin 2 on TO-92S, pin 3 on SOT-23-3L). |
| 3 | OUT | output | Open collector output pin with an integrated freewheeling diode; output voltage is rated -0.3 V to 40 V and output current is limited to 20 mA. |
