The Bourns P40-G240-WH is a high-speed bidirectional transient blocking unit (TBU) from the P40-G series, designed to protect sensitive electronics from surges caused by short circuits, AC power cross, induction, and lightning. It uses MOSFET semiconductor technology to trigger and block overcurrent events with a typical trigger current of 350 mA and a blocking time of just 0.2 µs.
The device provides impulse protection up to 40 V (rise time ≥ 1 µs) and continuous RMS protection up to 28 V. The maximum continuous current is 240 mA, and the maximum blocking current is 480 mA. Series resistance is typically 3.6 Ω, with a line-to-line resistance balance of 5%. Quiescent current is 0.7 mA at 40 V DC, and the reset voltage is 7 V.
The P40-G240-WH is housed in a surface mount 6-SMD, No Lead package (supplier package 6-DFN 4x4 mm). It operates over a temperature range of -55 °C to +125 °C and can be stored at -65 °C to +150 °C. The junction-to-air thermal resistance is 130 °C/W on a standard FR4 PCB with 0.035 sq. in. copper.
Common applications include xDSL line protection, high-speed data interfaces (LVDS, HDMI), and industrial sensor and control circuits. The device is RoHS3 compliant and UL recognized (file E315805).
