AS431BNTR-E1

Overview

The AS431BNTR-E1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides an output voltage programmable from 2.5V to 36V with a guaranteed initial accuracy of 1.0%. The device operates within a cathode current range of 1mA to 100mA and features a typical temperature coefficient of 20ppm/°C. It is housed in an SOT-23 surface-mount package and supplied in tape and reel format.

Feature Summary

Adjustable precise output voltage ranging from 2.5V to 36V
High stability under capacitive load conditions
Low equivalent full-range temperature coefficient
Sink current capacity spanning 1mA to 100mA

Applications

Charger circuits
Voltage adapters
Switching power supplies
Graphic cards
Precision voltage references

Procurement Notes

Verify the specific ordering suffix E1 confirms RoHS compliance and lead-free status as defined by the manufacturer. Confirm the package type matches the required SOT-23 footprint for PCB layout. Ensure the 1.0% voltage tolerance meets the design specifications. Check the datasheet for any recent production change notices or lifecycle status updates regarding this specific part number before finalizing procurement.

Selection Notes

Select this component when a low-cost, high-stability shunt regulator is needed for applications requiring programmable reference voltages up to 36V. The SOT-23 package suits space-constrained designs. Verify that the operating temperature range of -40°C to +125°C aligns with the environmental requirements. Consider the 1.0% initial accuracy if tighter tolerances are not critical for the application.

Part Context

The AS431 series serves as a versatile alternative to Zener diodes in various power management roles. It belongs to a family of adjustable precision shunt regulators offered in multiple packages including TO-92, SOT-23, SOT-25, and SOT-89. The BNTR-E1 variant specifically denotes the SOT-23 package with 1.0% tolerance and RoHS-compliant packaging.
