TDS4501P - Transient Diverting Suppressor

General Description

Transient Diverting Suppressors (TDS) are designed to provide protection from Electrical Overstress (EOS) events.

They have superior clamping and temperature characteristics when compared to standard TVS devices.

The device uses a surge rated FET as the main protection element.

Key Features

  • High ESD withstand Voltage: ±20kV (Contact) and ±30kV (Air) per IEC 61000-4-2.
  • High peak pulse current capability: 24A (tp = 8/20μs) per IEC 61000-4-5 ±1kV (tp = 1.2/50μs, RS = 42Ω ) per IEC 61000-4-5 for unsymmetrical lines.
  • High EFT Withstand Voltage: ±4kV (100kHz and 5kHz, 5/50ns) IEC 61000-4-4.
  • Protects one I/O or power line.
  • Working voltage: 45V.
  • Solid-state technology Mechanical Characteristics.
  • Package: DFN 1.6x 1.6 x 0.55mm.

TDS4501P Transient Diverting Suppressor 1-Line, 45V (24VAC) EOS Protection PROTECTION PRODUCTS Description Transient Diverting Suppressors (TDS) are designed to provide protection from Electrical Overstress (EOS) events. They have superior clamping and temperature characteristics when compared to standard TVS devices. The device uses a surge rated FET as the main protection element. A precisely tuned trigger circuit activates the shunt FET when an EOS event is detected. The TDS clamping voltage is nearly constant across the rated peak pulse current range due to the extremely low ON Resistance of the FET. TDS4501P is designed to protect voltage bus or data lines with an operating voltage as high as 45V (24VAC).
