Industry’s first reflowable thermal protection device replaces power FETs

Presented as the industry’s first surface-mountable reflowable thermal protection device, the RTP200R120SA (RTP200) can be used to replace redundant power FETs, relays, and heavy heat sinks. The first device in the RTP product family, the RTP200 can withstand multiple reflow passes with peak temperatures exceeding 200°C, and will also open when it detects temperatures above 200°C.

The device features a typical 1.2-mΩ series resistance, and high-current dc-interrupt ratings of 200 A at 16 Vdc and 100 A at 32 Vdc. it also helps protect against thermal-runaway damage caused by capacitors, ICs, resistors, and other power components that can crack and fail, or from the effects of any type of corrosion-induced heating in IT server, telecom power supply, and other industrial applications.

The device can be quickly and easily installed using industry-standard pick-and-place and Pb-free reflow equipment, which allows manufacturers to use cost-efficient surface-mount device processes instead of hand assembly. The RTP200 resists shock, vibration, temperature cycling, and humidity exposure, and is tested to meet or exceed automotive AECQ environmental and life-testing requirements. (Prototype samples, $0.48 ea/10,000 — 10 weeks ARO.)
