Product Description
Littelfuse SM05-02HTG 2-Element Bi-Directional TVS Diode Array delivers 400 W peak pulse power dissipation with a compact 3-Pin SOT-23 surface mount package. It protects sensitive electronic components from damaging electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges by clamping voltage spikes quickly and efficiently.
Featuring a dual diode configuration, this bi-directional array has a minimum breakdown voltage of 6 V and a maximum reverse stand-off voltage of 5 V, allowing it to guard circuits operating at low voltages. It is designed to handle peak pulse currents up to 24 A and offers a low clamping voltage of 13 V, crucial for protecting modern integrated circuits and microprocessor inputs.
The device supports a wide operating temperature range from -40°C to 125°C, making it suitable for use in industrial, automotive, telecommunications, and medical equipment. Certified to meet the AEC-Q101 automotive standard, it assures long-term reliability in harsh environments.
Its small form factor, measuring 3.04 mm by 1.4 mm by 3.04 mm, facilitates easy integration in compact designs. The diode array is engineered with very low dynamic resistance for efficient energy dissipation and boasts robust surge protection with a pulse duration of 8/20μs.
This TVS Diode Array effectively safeguards ports such as RS-232, RS-485, RS-422, RS-423, and DC power inputs found in various electronic devices including industrial controls, security systems, point-of-sale terminals, and test equipment.
