NJM431SF-TE1

Overview

The NJM431SF-TE1 is an adjustable precision shunt voltage reference manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range up to 36 V and supports a maximum shunt current of 100 mA. The device features an initial accuracy of 2% and provides a nominal output voltage of 2.495 V. It is designed for surface mount installation in SOT-23-5 packages, functioning reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Adjustable precision shunt regulation capability
• High input voltage tolerance up to 36 V
• Compact surface-mount packaging

Applications

• Precision voltage reference circuits
• Power management ICs
• Battery monitoring systems

Procurement Notes

Verify the specific suffix TE1 against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with SOT-23-5 footprint requirements. Confirm RoHS compliance status through manufacturer documentation before integration into production workflows.

Selection Notes

Select this component when a compact, adjustable shunt reference is required for space-constrained designs. Consider the 2% initial accuracy and 36 V maximum rating against circuit demands. Evaluate thermal performance within the specified -40°C to +85°C operating range for environmental suitability.

Part Context

This part belongs to the NJM431 series of adjustable shunt voltage references. It serves as a semiconductor integrated circuit within the Power Management IC category. The device functions similarly to standard zener-based references but offers superior adjustability and stability characteristics for precision analog applications.

Replacement Considerations

The NJM431U-TE1 is a documented alternative in the same series, utilizing an SOT-89-3 package instead of SOT-23-5. Verify pinout compatibility and physical dimensions before substitution.
