The SOT-23-5 package (SC-74A, SOT-753) is a common footprint for compact designs, and the operating temperature range of 0°C to 70°C limits it to commercial or indoor equipment — not automotive or extended industrial environments. ## Package and mounting — SOT-23-5, surface-mount only The SOT-23-5 footprint is standard and widely supported by PCB layout tools; no special thermal management is required at the 100 mA output ceiling, but good copper connection to the cathode pin helps with heat spreading in continuous high-current operation.","metaTitle":"TL431ACDBVR Shunt Voltage Reference, Adj 2.495V to 36V, ±1%","metaDescription":"TL431ACDBVR adjustable shunt voltage reference, 2.495V min, 36V max, ±1% tolerance, 100 mA output, SOT-23-5.
