AP432ASRG-7

Overview

The AP432ASRG-7 is a 3-terminal adjustable precision shunt regulator from Diodes Incorporated, belonging to the AP432A series. It features a reference voltage of 1.24V with ±0.5% tolerance and supports an output voltage range from 1.24V up to 20V via external resistors. The device offers a sink current capability of 200mA and requires a minimum cathode current of 150µA for regulation. It operates within a temperature range of -20°C to +85°C and is housed in an SOT-23R surface-mount package.

Feature Summary

Adjustable output voltage programmable up to 20V using external resistor dividers
High precision reference voltage with tight initial accuracy tolerance
Fast turn-on response characteristics suitable for replacing Zener diodes
Low dynamic output impedance ensuring stable regulation performance

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 this part is marked Not Recommended for New Design. Confirm package integrity and moisture sensitivity handling prior to assembly. Check for RoHS compliance status and ensure compatibility with existing PCB footprints. Validate that the specific ordering suffix matches required packaging and lead-free specifications before finalizing procurement orders.

Selection Notes

Select this component when high precision voltage referencing is required in space-constrained designs. The AP432A variant provides tighter tolerance compared to standard AP432 models. Consider the SOT-23R package for compact surface-mount applications. Evaluate thermal dissipation requirements against the specified power ratings for the chosen operating conditions.

Part Context

This device is part of the AP432 family of adjustable precision shunt regulators manufactured by Diodes Incorporated. It serves as a direct functional replacement for traditional Zener diodes in many linear regulation applications. The AP432A designation specifically indicates the higher precision version of the standard AP432 device.
