Key Features
- 60 V maximum operating voltage supporting 24 V and 48 V industrial power rails with load-dump tolerance
- 6 A continuous current rating with adjustable overcurrent threshold for programmable power limiting
- Integrated surge protection absorbing transients up to 60 V for robust industrial line protection
- Adjustable inrush current control via external capacitor to limit startup surge on capacitive loads
- Reverse polarity protection blocking reverse-current flow without external diodes or MOSFETs
Applications
The PTPS26633RGET protects 24 V and 48 V industrial power rails in PLC input modules, field instrument power supplies, and factory automation equipment from overcurrent, overvoltage, and surge transients. Its adjustable power-limiting function enables safe hot-plug insertion of industrial cards and sensor modules without nuisance tripping. Motor drive pre-charge circuits and I/O protection in DIN-rail power distribution also benefit from its integrated reverse-polarity and surge-absorption capabilities.

Frequently Asked Questions
What maximum voltage and current ratings does PTPS26633RGET support for industrial 48 V rail protection?
PTPS26633RGET is rated for 60 V maximum operating voltage and 6 A continuous current, making it directly suitable for protecting 48 V industrial bus rails with margin for load-dump transients, without requiring additional clamp diodes or external fuses in most applications.
How does PTPS26633RGET's inrush current control benefit a hot-pluggable industrial module design?
An external capacitor connected to the dV/dt pin programs the output slew rate, limiting inrush current during hot insertion of capacitive loads; for a 1000 µF bulk capacitor charged to 48 V, a properly chosen slew capacitor can cap inrush below 3 A, preventing connector arcing and nuisance overcurrent trips.
Does PTPS26633RGET provide reverse polarity protection, and how is it implemented?
Yes, PTPS26633RGET integrates reverse-polarity protection through an internal back-to-back MOSFET structure that blocks reverse current flow without the 0.6 V forward-voltage drop of a Schottky diode, reducing power loss at high currents and eliminating the need for an external series diode on 24 V or 48 V rails.
For a 24 V PLC I/O protection application, how does PTPS26633RGET compare to a traditional polyfuse in response time?
PTPS26633RGET responds to overcurrent events within microseconds using active electronic limiting, compared to hundreds of milliseconds for a polyfuse to reach trip temperature; this faster response better protects sensitive downstream circuits from short-circuit damage on 24 V industrial I/O cards.
