ZRC250R01

Overview

The ZRC250R01 is a precision micropower voltage reference utilizing bandgap circuit design to deliver a fixed 2.5V output. It operates within an industrial temperature range of -40°C to +85°C and requires no external stabilizing capacitor. The device supports a recommended operating current between 20µA and 5mA, with absolute maximum ratings allowing for transient currents up to 200mA. Key electrical parameters include a typical temperature coefficient of 30ppm/°C, a slope resistance of 0.4Ω, and a wideband noise voltage of 60µVrms. It achieves stable operating conditions in less than 10µs.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external capacitors.
• Low knee current operation enables suitability for low power and battery-powered applications.
• Rugged design withstands transient effects and high currents up to 200mA.
• Superior switching capability ensures rapid stabilization within microseconds.

Applications

• Battery powered and portable equipment
• Instrumentation
• Test equipment

Procurement Notes

Verify the specific package suffix against official documentation, as the R suffix denotes an E-Line 3-pin reversed configuration. Confirm that the ±1% tolerance variant matches the required accuracy for the target application. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed performance specifications.

Selection Notes

Select this component when space-saving surface mount or through-hole options are needed alongside precise voltage referencing. The low knee current makes it appropriate for battery-operated systems where minimizing quiescent consumption is critical. Consider the rugged transient handling capabilities if the application involves potential current spikes exceeding standard operating limits.

Part Context

This part belongs to the ZRC250 series from Diodes Incorporated, which offers various tolerance levels and package styles including SOT23, SO8, and E-Line configurations. The series is designed for applications requiring a stable 2.5V reference with minimal external components. The ZRC250R01 specifically utilizes the E-Line 3-pin reversed package format.

Replacement Considerations

Compatible substitutes within the same family include ZRC250A01 (E-Line 3-pin) and ZRC250Y01 (E-Line 2-pin), provided the pinout configuration aligns with the existing PCB layout. Verify that alternative packages support the required thermal dissipation and mechanical mounting constraints.
