4 / 27 page LM3401 SNVS516C – AUGUST 2007 – REVISED MAY 2013 www.ti.com ELECTRICAL CHARACTERISTICS Specifications in standard type are for TJ = 25°C only, and limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Unless otherwise stated, VIN = 24V. Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only (1).

All limits at temperature extremes are specified through correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (2) IQ specifies the current into the VIN pin and applies to non-switching operation. 4 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: LM3401 |
