Product Description
Littelfuse SP0503BAHTG is a 3-element uni-directional TVS diode array designed for protecting sensitive electronic components from transient voltage spikes and electrostatic discharge events. This diode array dissipates peak pulse power of 0.22 W and features a 4-pin SOT-143 surface mount package measuring 3.04 mm in length, 1.4 mm width, and 1.07 mm height, making it suitable for compact circuit designs.
Operating temperature range from -40°C to 85°C ensures reliability in harsh industrial, automotive, and consumer electronic environments. The device has a minimum breakdown voltage of 6 V and a clamping voltage of 8.5 V for effective suppression of harmful voltage transients.
These TVS diode arrays are critical components in ESD protection circuits to safeguard semiconductors and other sensitive electronics against electrical overstresses. The SP05 series with the model SP0503BAHTG is surface-mounted using industry-standard footprints for ease of PCB assembly and integration. It also features a maximum reverse stand-off voltage of 5.5 V and a low maximum reverse leakage current of 100 nA, optimizing power efficiency during normal operation.
The 3-element per chip configuration enhances transient suppression capability providing multi-node protection points on PCB designs. Though this model does not carry automotive certification, it is broadly applicable to industrial, laboratory instrumentation, consumer electronics, and other commercial applications requiring robust transient voltage protective devices.
This diode array supports effective protection from transient voltage and ESD events in delicate circuitry. Compact SOT-143 package allows high-density PCB layouts with reliable surface mount capability. Wide operating temperature range accommodates industrial and commercial electronic environments.
Three element configuration offers versatile circuit protection options on a single chip. Low leakage current minimizes power losses and contributes to energy-efficient system designs.
