TE CONNECTIVITY / RAYCHEM ZEN056V130A24GS Zener Single Diode, 5.6V, 700mW, SMD, 3Pins, 85℃
The is a polymer enhanced precision Zener Diode designed in micro-assemblies that help protect sensitive electronics from damage caused by inductive voltage spikes, voltage transients, use of incorrect power supplies and reverse bias. The PolyZen micro-assembly incorporates a stable Zener diode for precise voltage clamping and a resistively non-linear, polymeric positive temperature coefficient PPTC layer that responds to either diode heating or overcurrent events by transitioning from a low to high resistance state. This device help provide resettable protection against damage caused by multi-watt fault events. It can be used in portable media players, global positioning systems, hard disk drives 5V and 12V bus, solid state drivesSSD 5V bus, cell phone charger port and USB power, automotive peripheral input power, DC power port protection and industrial handheld POS.
