ZTL432AQFTA

Diodes Incorporated · Voltage Reference · SOT-23

ZTL432AQFTA from Diodes Incorporated, in a SOT-23. 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 REF input Reference input pin. The internal error amplifier compares this pin to the 2.5V internal bandgap reference (VREF). Typical reference input current IREF = 2µA (max 4µA at IKA = 10mA, R1 = 10kΩ). Input current range −50µA to +10mA.
2 CATHODE power_in Cathode (K) - the regulator's active shunt terminal. Sinks 1mA to 100mA in regulation; VKA operating range VREF (2.5V) to 20V, absolute max 20V, continuous cathode current 150mA max. Off-state leakage 0.1µA typ (0.5µA max) at VKA = 20V.
3 ANODE power_in Anode (A) - reference return / ground for the device. All voltage specifications (VKA, VREF) are referenced to this pin.
