ZRC250A02STZ

Overview

The ZRC250A02STZ is a precision micropower voltage reference IC manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to provide a fixed output voltage of 2.5V with an initial tolerance of ±2%. The device operates within a recommended current range of 20µA to 5mA and features a typical temperature coefficient of 30ppm/°C. It is housed in a TO-92 style package suitable for through-hole mounting.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring an external stabilizing capacitor
• Capable of withstanding transient effects and currents up to 200mA due to rugged design
• Fast transient response reaches stable operating conditions in less than 10µs

Applications

• Battery powered and portable equipment
• Instrumentation
• Test equipment

Procurement Notes

Verify the specific suffix STZ against official documentation to confirm the exact package type and pin configuration, as ordering suffixes define physical attributes. Ensure compatibility with existing PCB footprints before procurement. Confirm component availability status directly with the manufacturer or authorized distributors.

Selection Notes

Select this component when a precise 2.5V reference is required in low-power applications. The ±2% tolerance suits general instrumentation needs. Verify that the TO-92 through-hole package aligns with the target assembly process. Consider the 20µA minimum knee current for battery life optimization.

Part Context

This part belongs to the ZRC250 series of precision voltage references from Diodes Incorporated. The series offers various tolerance options (±1%, ±2%, ±3%) and package types including SOT23, SO8, and E-Line styles. The ZRC250A02 specifically denotes the 2% tolerance variant in the E-Line family.
