Littelfuse LCAS Series P1zOOSC Asymmetrical Discrete SIDACtor® Devices

Category: Electronics, Littelfuse Inc, Trigger Devices

Overview

The Littelfuse P1zOOSC Series from the LCAS product line comprises Asymmetrical Discrete SIDACtor® devices designed for protecting telecommunication equipment against lightning transients and power surges. This protected element is suitable for telecom tip and ring applications. These SIDACtor® devices offer symmetrical bidirectional protection. They meet industry standards for electronic equipment safety and performance.

Key Parameters

These SIDACtor® devices are provided in a DO-214AA package with a surface mount method for installation. The series is defined by several key parameters:
Peak Off-state Voltage: The device has different peak off-state voltage ratings, with a first V_DRM1 rating of 100V and a second V_DRM2 rating of 130V.
Switching Voltage: The switching voltages at these off-state voltages are 4.0000V and 800V, respectively, indicating the threshold for the device to switch to on-state.
On-state Voltage & Current: It has an on-state voltage V_T up to 45.0V and a forward on-state voltage V_P, with maximum leakage currents (I_DRM) and switching currents (I_{S MAX}) specified in milliamperes.
Holding Current: The devices support a minimum holding current (I_{H MIN}) which ensures stability in the non-conducting state.

Performance Capabilities

The performance capabilities of the devices include a range of peak pulse current ratings for various waveforms:
Capacity Ratings: The devices have a maximum off-state capacitance (C_o) of 110pF and a minimum off-state capacitance value not specified.
Peak Pulse Current: The SIDACtor® can withstand peak pulse currents of 500A (2x10A/μs), 400A (8×20μs), 200A (10×160μs), and 150A (10×560μs) for different standard waveform durations. It can handle pulse currents up to 100A (10×1000μs) and 50A for (5×310μs) and (5×320μs) waves.
Surge Current and Rate of Rise: The datasheet also details the peak one-cycle surge current (I_TSM @ 60Hz) of 50A, as well as the maximum rate of rise of current (di/dt MAX) being 500A/μs.
