Overview
The onsemi TL431ACLPRE is a three-terminal programmable shunt regulator diode in the TL431 series. It operates as a low temperature coefficient Zener, programmable from Vref to 36 V using two external resistors. The device features a reference voltage tolerance of ±1% and an equivalent full-range temperature coefficient of 50 ppm/°C typical. It supports a cathode current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. Designed for commercial applications, it functions within an operating ambient temperature range of 0°C to +70°C.
Feature Summary
- Programmable output voltage capability up to 36 V via external resistors
- Temperature compensated operation across the rated ambient temperature range
- Low dynamic output impedance for stable regulation performance
- Pb-Free package construction compliant with RoHS standards
Applications
- Digital voltmeters
- Power supplies
- Op amp circuitry
- Shunt regulators
Procurement Notes
Verify the specific suffix 'E' against official documentation to confirm tape and reel packaging details for the TO-92 (TO-226) case. Ensure the commercial temperature grade (0°C to +70°C) aligns with system requirements. Confirm Pb-Free status and RoHS compliance through manufacturer declarations before procurement.
Selection Notes
Select this component when a precise, adjustable voltage reference is required in commercial environments. The ±1% tolerance suits applications needing tighter accuracy than standard Zener diodes. Verify that the 0°C to +70°C operating range meets thermal constraints. Consider the TO-92 package for through-hole mounting needs.
Part Context
This part belongs to the TL431, A, B Series from onsemi, which are monolithic IC voltage references. The series includes variants like NCV431A for automotive use. The TL431ACLPRE specifically denotes the 'A' grade with 1% tolerance, 'CL' indicating the TO-92 package, and 'PRE' specifying the tape and reel shipping configuration.
Replacement Considerations
Compatible substitutes include TL431ACLPRAG and TL431ACDR2G. Verify pinout compatibility and electrical specifications such as reference voltage tolerance and operating temperature range when substituting.
