LM185H-1.2/883

Overview

The LM185H-1.2/883 is a micropower shunt voltage reference diode manufactured by Texas Instruments, designed for high-reliability applications requiring stable voltage regulation. This component operates as a two-terminal device providing a nominal output voltage of 1.2V. It is qualified under the MIL-PRF-38534 standard, indicated by the /883 suffix, ensuring compliance with stringent military specifications for performance and durability in harsh environments.

Feature Summary

Provides a stable 1.2V reference voltage using micropower shunt technology
Qualified to MIL-PRF-38534 standards for high reliability
Designed for operation in demanding environmental conditions

Applications

Military aerospace instrumentation systems
High-reliability data acquisition circuits
Precision measurement equipment requiring strict stability

Procurement Notes

Verify that the /883 suffix confirms qualification to MIL-PRF-38534 Class H or K standards. Ensure the manufacturer source is authorized for defense-grade components. Confirm lot traceability and test reports are available for compliance auditing. Check for specific screening requirements mandated by the end-use application.

Selection Notes

Select this part when military-grade reliability and radiation hardness are required. Compare against commercial equivalents like the LM185BZ if cost is a primary constraint and environmental stress is low. Consider package constraints as TO-92 variants may differ from hermetic metal can options. Validate thermal management needs against the specific power dissipation limits defined in the datasheet.

Part Context

This component belongs to the LM185/LM285/LM385 family of micropower voltage references. The LM185 variant represents the commercial temperature range version within this lineage. The /883 designation distinguishes it from standard commercial parts by adding military qualification layers, including burn-in and lot acceptance testing protocols not present in lower-tier versions.
