What are the key features of PTGL07AS150K6B51B0?
- 15 Ω room-temperature resistance with 1700 mW power rating providing self-resetting overcurrent protection without a fuse
- Through-hole radial disk package (7.3 mm diameter × 4.5 mm) enabling direct PCB insertion into standard 2-pin through-hole footprints
- Positive temperature coefficient characteristic automatically increases resistance to limit fault current, resetting after the fault is cleared
What is PTGL07AS150K6B51B0 used for?
PTGL07AS150K6B51B0 is used as a resettable overcurrent protection element in power supply inputs, motor drive circuits, and battery chargers where a self-resetting protection device is preferred over one-time fuses. Its 15 Ω initial resistance and 1700 mW power dissipation rating allow it to handle normal operating current while tripping quickly under fault conditions. The radial through-hole disk package integrates easily into power electronic PCBs for white goods, industrial equipment, and consumer electronics requiring reliable thermal runaway and overcurrent protection.

Frequently Asked Questions
What is the initial resistance and power rating of PTGL07AS150K6B51B0 for overcurrent protection circuit design?
PTGL07AS150K6B51B0 has a rated initial resistance of 15 Ω and a power dissipation rating of 1700 mW at room temperature. These values determine the hold current and trip threshold in overcurrent protection circuits for power supplies, motor inputs, and battery charger designs.
How does the PTC thermistor behavior of PTGL07AS150K6B51B0 provide self-resetting protection?
Under overcurrent or overtemperature conditions, the PTGL07AS150K6B51B0 PTC thermistor's resistance increases sharply by several orders of magnitude, limiting fault current to a safe level. Once the fault is cleared and the device cools, its resistance returns to approximately 15 Ω, resetting automatically without replacement — unlike a one-time fuse.
What are the physical dimensions of PTGL07AS150K6B51B0 and how does it mount on a PCB?
PTGL07AS150K6B51B0 is a radial through-hole disk package measuring 7.3 mm in diameter and 4.5 mm in width, with radial leads for direct PCB insertion into 2-pin through-hole pads. This package style suits power protection circuits on larger PCBs in industrial drives, white goods, and AC-DC converter boards.
In which power protection applications is a 15 Ω PTC thermistor like PTGL07AS150K6B51B0 preferred over a traditional fuse?
A 15 Ω PTC thermistor at 1700 mW is preferred in applications requiring automatic reset after a fault, such as inrush current limiting on power supply inputs, motor winding protection, and battery charger overcurrent guards. Unlike a 1-shot fuse, the PTC resets when the fault clears, reducing field maintenance costs in industrial and consumer equipment with 8 or more protection channels.
