ZR40402R50STOB

Overview

The ZR40402R50STOB is a precision micropower voltage reference providing a nominal output of 5.0V, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and is housed in an E-Line (TO-92 style) package with the 'R' suffix indicating this specific form factor. The device operates within a current range of 60µA to 15mA, ensuring stability without external capacitors. It features a typical temperature coefficient of 20ppm/°C and maintains performance across an operating temperature range of -55°C to +125°C.

Feature Summary

• Bandgap circuit design for precision voltage regulation
• Capacitor-free stability with capacitive load tolerance
• Robust transient handling up to 200mA surge currents
• Fast stabilization time reaching stable conditions in under 10µs

Applications

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

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm the physical package type and pinout configuration. Ensure that the specified tolerance level matches the application requirements before procurement. Confirm availability status as manufacturing lifecycles may change. Cross-reference part numbers carefully to avoid confusion between different package variants within the same series.

Selection Notes

Select this component when space constraints allow through-hole mounting but high precision is required. The wide operating current range supports low-power designs while the rugged construction handles transient loads. Consider the temperature coefficient specifications relative to the environmental conditions of the target application. Evaluate the need for capacitor-free operation versus other reference types offering lower noise or tighter tolerances.

Part Context

This component belongs to the ZR4040-5.0 series of precision voltage references from Diodes Incorporated. The series offers both surface mount SOT23 and through-hole E-Line packages. The '2' in the part number indicates a 2% initial accuracy tolerance. The 'R' suffix specifically denotes the E-Line, 3-pin reversed package variant, distinguishing it from the SOT23 'F' suffix versions.
