Semtech 1-Element Uni-Directional TVS Diode Array 500 W, 4-Pin SOT-143 SR05.TCT

Semtech SR05.TCT is a high-performance 1-element uni-directional TVS diode array designed for robust transient voltage suppression of sensitive electronic circuits. Packaged in a compact 4-pin SOT-143 surface mount configuration, this component delivers a peak pulse power dissipation of 500 W, making it ideal for safeguarding power lines and communication interfaces from voltage spikes.

With a minimum breakdown voltage of 6 V and a maximum reverse stand-off voltage of 5 V, the SR05.TCT efficiently clamps voltage surges to a safe 20 V level. It is rated for operation in a wide temperature range from -55°C to 125°C, supporting demanding industrial and commercial applications.

The component provides electrostatic discharge (ESD) protection compliant with IEC 61000-4-2 standards, capable of withstanding ±15 kV air discharge and ±8 kV contact discharge levels. Furthermore, it resists electrical fast transients (EFT) and lightning-induced surges per IEC 61000-4-4 and IEC 61000-4-5 standards.

The diode array's low capacitance design helps maintain signal integrity on protected I/O lines, making it suitable for telecommunication, automotive electronics, industrial controls, and consumer devices requiring reliable overvoltage protection.

Features uni-directional diode configuration suitable for single line protection. Supports peak pulse power dissipation of 500 watts for transient voltage suppression. Operates between -55°C and 125°C ensuring reliability under harsh conditions.

Compact SOT-143 surface mount package with 4 pins for easy PCB integration. Low capacitance design minimizes signal distortion in communication lines. Protects against ESD events compliant with IEC 61000-4-2 (±15kV air, ±8kV contact).

Offers surge protection against EFT and lightning induced transients per IEC standards. Clamping voltage of 20V and minimum breakdown voltage of 6V provide effective suppression. Maximum peak pulse current of 25A handles high surge currents safely.

This Semtech TVS diode array is ideally suited for industrial, commercial, telecommunications, automotive, and consumer electronic applications requiring reliable transient voltage suppression to protect sensitive components and improve system robustness.
