LM285Z-1.2RA

Overview

The onsemi LM285Z-1.2RA is a micropower shunt voltage reference diode housed in a TO-92 package. It provides a fixed nominal reference voltage of 1.235V with an initial accuracy of ±2%. The device operates within a current range of 10µA to 20mA and features a temperature coefficient of 80ppm/°C. Designed for through-hole installation, it supports a maximum shunt current of 20mA and functions reliably across a temperature range of 0°C to 70°C.

Feature Summary

Micropower operation suitable for battery-powered applications
Low dynamic impedance for stable regulation
Fixed reference voltage output
Through-hole TO-92 packaging

Applications

Portable instrumentation
Battery-powered circuits
Voltage regulation

Procurement Notes

Verify the specific manufacturer suffix 'RA' against official datasheets to confirm exact binning or tolerance specifications. Ensure the component source is authorized to guarantee authenticity. Confirm that the TO-92 package variant matches the required PCB footprint and lead configuration for the target assembly process.

Selection Notes

Select this component when a low-cost, fixed 1.235V reference is needed for low-current applications. It is appropriate for designs requiring through-hole mounting and operating temperatures up to 70°C. Consider alternative packages if surface-mount technology is required or if wider industrial temperature ranges are necessary.

Part Context

This part belongs to the LM285/LM385 family of micropower bandgap voltage references. These devices are designed to operate over a wide current range while maintaining low noise and high stability. The LM285 series is commonly used as a precision reference in analog circuits where power consumption must be minimized.
