AS431AZTR-E1

Overview

The AS431AZTR-E1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides an output voltage range from 2.5V to 36V with a guaranteed initial accuracy of ±0.5%. The device features a typical temperature coefficient of 20ppm/°C and supports a cathode current range from 1mA to 100mA. It operates within an ambient temperature range of -40°C to +125°C and utilizes a TO-92 package with Ammo packing.

Feature Summary

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

Applications

Switching power supplies
Chargers
Voltage adapters
Graphic cards
Precision voltage references

Procurement Notes

Verify the specific ordering suffix 'E1' indicates RoHS compliance and lead-free status as defined by Diodes Incorporated. Confirm that the 'Z' package designation corresponds to the TO-92 form factor with Ammo packing. Ensure the component matches the required 0.5% voltage tolerance for the intended circuit design before finalizing procurement.

Selection Notes

Select this component when a high-precision reference with low temperature drift is required in a through-hole configuration. The 0.5% tolerance ensures tight voltage regulation compared to standard Zener diodes. Verify that the TO-92 Ammo packaging aligns with available assembly equipment and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the AS431 family of adjustable precision shunt regulators, serving as a direct replacement for traditional Zener diodes in various power management applications. The series offers multiple package options including SOT23, SOT25, and SOT89, with the AZ variant specifically denoting the TO-92 package and 0.5% tolerance level.
