4 / 38 page LM3406, LM3406HV, LM3406HV-Q1 SNVS512E – SEPTEMBER 2008 – REVISED MARCH 2014 www.ti.com 6 ELECTRICAL CHARACTERISTICS LM3406/LM3406HV/LM3406HV-Q1 VIN = 24V unless otherwise indicated. Unless otherwise specified, datasheet typicals and limits apply to LM3406, LM3406HV and LM3406HV-Q1. Typicals and limits appearing in plain type apply for TA = TJ = +25°C (1). Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are specified by design, test, or statistical analysis.
