Obsolete — sourcing path and replacement
The typical on-resistance is 20 mOhm. At 13.5 A maximum continuous output current, the conduction loss is the thermal load the TO-220AB package must dissipate.
Built-in fault protection
Fixed current limiting and over-temperature shutdown are integrated — no external sense resistor or comparator needed. The current limit clamps the output at a fixed threshold; if the junction exceeds the thermal trip point, the switch latches off until it cools. This makes the part suitable for driving resistive, inductive, or lamp loads in harsh industrial environments where fault conditions are expected.
Package and mounting — TO-220AB
The through-hole TO-220AB package (3-lead) has a metal tab for heatsink attachment. The tab is electrically connected to the drain (output) — an insulating pad and washer are needed if the heatsink is grounded. The mounting hole accepts a standard M3 screw; torque to the datasheet specification to avoid cracking the plastic body.
