TL431BVDG

Overview

The TL431BVDG is a three-terminal programmable shunt regulator diode from onsemi, operating within the TL431A and B series. It functions as a low temperature coefficient zener reference, adjustable from Vref to 36 V using two external resistors. The device supports a wide cathode current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. It features a voltage reference tolerance of ±0.4% at 25 °C and an equivalent full-range temperature coefficient of 50 ppm/°C. Packaged in SOIC-8 (D suffix), it operates over an ambient temperature range of -40 °C to +125 °C.

Feature Summary

Programmable output voltage capability up to 36 V
High precision initial accuracy of ±0.4%
Extended high-temperature operation up to +125 °C
Low dynamic output impedance for stable regulation

Applications

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

Procurement Notes

Verify the specific ordering suffix 'D' confirms the SOIC-8 package type and standard shipping configuration. Confirm that the 'BV' marking code aligns with the required -40 °C to +125 °C operating temperature range. Ensure compliance with Pb-Free and RoHS standards if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a precise, adjustable shunt reference is required across a wide temperature spectrum. The ±0.4% tolerance suits applications demanding tight voltage accuracy without external trimming. The extended thermal rating makes it suitable for automotive or industrial environments where ambient temperatures exceed standard commercial limits.

Part Context

This device belongs to the TL431 family of programmable precision references manufactured by onsemi. It serves as a direct replacement for standard Zener diodes in many linear and switching applications. The BV designation specifically indicates the high-temperature variant within the B-series lineup, offering improved performance stability under elevated thermal stress conditions.
