Overview
The AP432ARG-7 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated, housed in an SC-59R surface-mount package. It features a reference voltage of 1.24V with ±0.5% tolerance and supports programmable output voltages up to 20V using external resistors. The device provides a sink current capability of 200mA with a minimum cathode current for regulation of 150µA. It exhibits a dynamic output impedance of 0.2Ω and operates within a temperature range of -20°C to +85°C.
Feature Summary
- Adjustable precision shunt regulation with low dynamic output impedance
- High accuracy reference voltage with tight initial tolerance
- Fast turn-on response characteristics suitable for active circuitry
Applications
- Precision voltage monitoring circuits
- Over-voltage and under-voltage protection systems
- Constant-current sinks and sources
- Crowbar protection circuits
Procurement Notes
Verify component authenticity through authorized channels as the part is marked Not Recommended for New Design. Confirm package marking codes match the SC-59R designation. Check datasheet revision history for any process changes. Ensure compliance with RoHS and Halogen-free requirements if specified for the application environment.
Selection Notes
Select this component when a low-cost, high-accuracy shunt regulator is required for voltage referencing or regulation. Consider the SC-59R package constraints for PCB layout. Evaluate stability boundary conditions regarding load capacitance and cathode current before implementation. Verify that the operating temperature range meets system environmental requirements.
Part Context
This device belongs to the AP432 family of adjustable precision shunt regulators from Diodes Incorporated. It serves as a functional alternative to Zener diodes, offering superior temperature stability and lower dynamic impedance. The specific ARG suffix indicates the ±0.5% tolerance variant packaged in SC-59R format.
Replacement Considerations
The manufacturer recommends using the AZ431L as a replacement for new designs. Verify pinout compatibility and electrical parameter equivalence before substituting.
