ZXRE252BSA-7

Overview

The ZXRE252BSA-7 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of 2.5V to 36V and supports a sink current capability from 0.065mA to 100mA. The device features an initial reference voltage tolerance of ±0.5% at +25°C, with a typical reference voltage of 2.495V. It exhibits a minimum cathode current for regulation of 40µA (typical) and maintains operation across a temperature range of -40°C to +125°C.

Feature Summary

Adjustable output voltage set via external divider resistors
Very low minimum cathode current for regulation
Low dynamic output impedance
Totally lead-free and fully RoHS compliant

Applications

Optocoupler linearisers
Shunt regulators
Improved Zener diode replacement
Variable reference circuits

Procurement Notes

Verify the component datasheet revision and ordering information before procurement. Confirm that the specific suffix matches the required pinout and package type. Ensure compliance with environmental directives such as RoHS and Halogen-free requirements. Check for any product change notices or end-of-life notifications associated with this part number prior to finalizing supply agreements.

Selection Notes

Select the ZXRE252BSA-7 when high accuracy is required, indicated by the B grade's 0.5% initial tolerance. Choose this model over the A grade if tighter voltage specifications are necessary. Consider the low minimum cathode current for battery-powered applications where standby power consumption must be minimized. Verify that the SOT-23 package fits the available PCB space constraints.

Part Context

This component belongs to the ZXRE25x series of adjustable precision shunt regulators. It serves as a direct replacement for industry-standard devices like the '431 but offers improved performance through lower minimum operating currents. The series includes variants with different tolerances and packages, providing flexibility for various power management and reference voltage applications in consumer and industrial electronics.
