Load switches with best-in-class current capability and lowest saturation voltage

NXP low VCEsat load switches
PBLS20xD and PBLS60xD
Application example
A small control (on/off) current (= base TR2) switches a high output (= collector TR1) current

Designed to simplify circuit design and reduce pick-and-place costs, these load switches combine
an energy-saving low VCEsat transistor with a resistor-equipped transistor (RET) in a single package.
They’re housed in SOT457 packages, offer the highest current-per-footprint ratings on the market,
and are ideal for switching positive supply rails or ground-referenced loads.
