Overview
The AP432WG-7 is an adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a voltage range of 1.24 V to 20 V and supports a maximum cathode current of 200 mA. The device features a typical dynamic output impedance of 0.2 Ω and an equivalent full-range temperature coefficient of 30 ppm/°C. It functions with a minimum cathode current for regulation of 150 µA and maintains an operating temperature range from -20 °C to +85 °C.
Feature Summary
- Adjustable output voltage capability via external resistor divider network
- Low dynamic output impedance for stable regulation performance
- Fast turn-on response characteristics suitable for active circuitry applications
Applications
- Replacement for Zener diodes in voltage reference circuits
- Programmable output voltage control systems
- Precision shunt regulation in power management ICs
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation, as package designations vary across the AP432 family. Confirm availability status directly with authorized distributors due to potential discontinuation notices associated with this product line. Ensure compliance with RoHS3 specifications if required for your manufacturing process.
Selection Notes
Select this component when a low-cost, high-precision shunt regulator is needed to replace discrete Zener diodes. Consider the 200 mA sink current capability and 0.2 Ω output impedance for load regulation requirements. Verify that the SC-59 or SOT-23 package options align with your PCB layout constraints and thermal management needs.
Part Context
This part belongs to the AP432 series of three-terminal adjustable precision shunt regulators produced by Diodes Incorporated. These devices are designed to provide stable reference voltages over extended commercial temperature ranges. The series serves as a direct functional alternative to traditional Zener diodes while offering superior accuracy and lower noise characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers include AZ431LANTR-E1 and LX432CSC. Verify pinout compatibility and electrical parameter alignment before implementation.
