NCP431ACLPRAG

Overview

The NCP431ACLPRAG is a programmable precision shunt reference diode in a TO-92 package. It features a typical voltage reference tolerance of ±1% at 25°C and operates over an ambient temperature range of 0°C to +70°C. The device supports a cathode-to-anode voltage up to 36 V with a continuous current range of 40 µA to 100 mA. It exhibits a low dynamic impedance of 0.22 Ω typical and a full-range temperature coefficient of 50 ppm/°C typical.

Feature Summary

Programmable output voltage adjustable from the internal reference level up to 36 V using external resistors
Low minimum operating current enabling extremely low no-load consumption in secondary regulators
Temperature compensated for stable operation across the rated industrial temperature range

Applications

Voltage adapters
Switching power supplies
Precision voltage references
Chargers
Instrumentation

Procurement Notes

Verify the specific suffix 'ACLPRAG' corresponds to the TO-92 package, 1% tolerance, and 0°C to +70°C temperature range. Confirm RoHS compliance status via the manufacturer's latest documentation. Check for any discontinuation notices or alternative package recommendations for new designs.

Selection Notes

Select this component when a through-hole TO-92 form factor is required for programmable shunt regulation. Ensure the application operates within the 0°C to +70°C environmental limits. Verify that the 1% initial accuracy meets the circuit requirements compared to higher precision alternatives like the B-series variants.

Part Context

This part belongs to the NCP431 series of three-terminal programmable shunt regulator diodes manufactured by onsemi. These devices serve as low-temperature coefficient zener equivalents, offering precise voltage referencing capabilities suitable for replacing standard zener diodes in various analog and digital circuits.
