Diodes Incorporated · Voltage Reference · TO-92-2.54mm
AZ431AZ-ATRG1 from Diodes Incorporated, in a TO-92-2.54mm. 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 | REF | input | Reference (sense) input of the shunt regulator, with VREF of 2.5 V (2.490 to 2.510 V for the 0.4% grade and 2.480 to 2.520 V for the 0.8% grade at IKA = 10 mA) and a reference input current limit of 10 mA. |
| 2 | ANODE | passive | Common anode terminal; the datasheet gives no separate pin-specific limit, so the cathode-to-anode limits apply (VKA from VREF to 36 V recommended, 40 V absolute maximum). |
| 3 | CATHODE | passive | Cathode terminal whose voltage must stay between VREF and 36 V and whose current is 1.0 to 100 mA in recommended operation (absolute maximum cathode current range -100 to 150 mA). |
