TL431BIDMR2G

Overview

The onsemi TL431BIDMR2G is a three-terminal programmable shunt regulator diode housed in an 8-pin Micro8 package. It operates as a low temperature coefficient zener, providing a reference voltage adjustable from Vref to 36 V using two external resistors. The device features a typical initial tolerance of ±0.4% at 25 °C and supports a cathode current range of 1.0 mA to 100 mA. It exhibits a typical dynamic impedance of 0.22 Ω and an equivalent full-range temperature coefficient of 50 ppm/°C. The component is designed for surface mount applications with an operating ambient temperature range of -40 °C to +85 °C.

Feature Summary

Programmable output voltage capability up to 36 V
High precision voltage reference with ±0.4% tolerance
Low dynamic output impedance for stable regulation
Temperature compensated operation across the rated range

Applications

Digital voltmeters
Power supply feedback loops
Op amp circuitry
Constant current sources

Procurement Notes

Verify the specific suffix 'DM' corresponds to the Micro8 package configuration required for your design. Confirm that the -40 °C to +85 °C operating temperature range meets your environmental specifications. Ensure the ±0.4% tolerance aligns with your circuit accuracy requirements before finalizing procurement.

Selection Notes

Select this component when a precise, adjustable shunt reference is needed in a compact surface-mount footprint. The Micro8 package offers space efficiency compared to standard SOIC-8 variants. Consider the thermal characteristics and stability boundary conditions if significant load capacitance is present in the application circuit.

Part Context

This part belongs to the TL431A/B series of programmable precision references manufactured by onsemi. It serves as a direct replacement for traditional Zener diodes in many analog and power management circuits. The device integrates internal compensation to maintain stability over its specified operating current range.
