Product Description
Littelfuse SP712-02HTG is a 2-element bi-directional TVS diode array designed for protecting electronic circuits, specifically RS-485 applications, from damaging electrostatic discharge, electrical fast transients, and lightning-induced surges.
This diode array features a compact 3-pin SOT-23 surface mount package, combining high performance with minimal board space requirement. It absorbs repetitive ESD strikes surpassing IEC 61000-4-2 standards without degradation, providing reliable protection.
The device delivers a peak pulse power dissipation of 640 W and can safely dissipate surge currents up to 20 A (8/20 µs waveform), ensuring robust defense against transient events. Its working voltage range of -7 V to 12 V suits asymmetrical voltage circuits and ensures compatibility with RS-485 communication lines.
The SP712-02HTG operates effectively over a broad temperature range from -40°C to 125°C and meets stringent automotive AEC-Q101 qualifications, making it suitable for industrial, automotive, HVAC, and manufacturing systems requiring high surge immunity.
With a low clamping voltage of 32 V and minimal leakage current, the device minimizes circuit stress and energy loss during transient suppression. The compact size - 3.04 mm length, 2.64 mm width, and 1.15 mm height - makes it ideal for dense PCB layouts and space-constrained applications.
Surface mount package SOT-23 with 3 pins for easy PCB integration. Two elements per chip bi-directional diode for comprehensive protection. 640 W peak pulse power dissipation for high energy transient mitigation. Complies with IEC 61000-4-2 for ESD protection at ±30 kV contact and air.
Supports surge currents of 20 A per IEC 61000-4-5 (8/20 µs). Wide temperature operating range and AEC-Q101 automotive qualification. Low clamping voltage reduces circuit stress during transient events. Designed for use in industrial, automotive, and communication electronics.
Compact size suitable for space-constrained PCB designs. This Littelfuse TVS Diode Array is essential for protecting sensitive electronic equipment in demanding environments, ensuring prolonged reliability and reduced downtime.
