ZR40402R25

Overview

The ZR40402R25 is a precision micropower voltage reference providing a fixed output of 2.5 volts, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and is housed in an E-Line, 3-pin (TO92 style) package with the suffix R. The device operates within a recommended current range of 60 µA to 15 mA and maintains stability without requiring an external stabilizing capacitor. It features a typical temperature coefficient of 30 ppm/°C and offers initial accuracy tolerances of 2%. The component supports operation between -40°C and +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20-volt processing.
• Provides superior switching capability with stable operating conditions reached in less than 10 microseconds.

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation
• Test equipment
• Data acquisition systems

Procurement Notes

Verify the specific package configuration and tolerance level required for the application before procurement. Confirm that the E-Line, 3-pin package variant aligns with the board layout constraints. Ensure the operating current requirements fall within the specified 60 µA to 15 mA range for optimal performance. Check for any specific environmental or compliance certifications relevant to the project specifications.

Selection Notes

Select this component when a compact, low-power voltage reference is needed for space-constrained designs. The TO92 style package is suitable for through-hole applications where surface-mount options are not preferred. Consider the 2% tolerance if higher precision variants like the 0.5% option are not strictly necessary. Evaluate the thermal environment to ensure it remains within the -40°C to +85°C operating range.

Part Context

This part belongs to the ZR4040 series of precision voltage references from Diodes Incorporated. The series includes various output voltages and tolerance levels, available in both SOT23 and E-Line packages. The ZR4040-2.5 specifically targets applications requiring a stable 2.5-volt reference with micropower consumption characteristics.
