GLF adds low-loss ideal diode line for battery-powered devices

GLF Integrated Power introduced the GLF1800 Series of ideal diodes on July 23, 2026, targeting wearables, smart meters and other low-voltage systems. The MOSFET-based parts are designed to cut forward voltage drop, reduce heat and simplify power-path protection in compact designs.

Why it matters: - The GLF1800 Series gives designers a replacement for Schottky diodes in battery-powered products. - The parts aim to cut power loss, which can extend battery life and reduce thermal stress in always-on devices. - The series is aimed at wearables, smart glasses, smart meters, wearable medical devices and IoT sensors.

What happened: - GLF Integrated Power introduced the GLF1800 Series of ideal diodes on July 23, 2026. - The company says the series uses a low-loss MOSFET-based architecture instead of Schottky diodes. - The product line includes GLF1800 and GLF1800T/AT variants.

The details: - GLF1800 has a forward voltage drop of 117 mV. - GLF1800T/AT has a forward voltage drop of 73 mV. - The devices feature ultra-low static current and ultra-low turn-off current. - The series supports an input voltage range of 1.8 V to 5.5 V. - The diodes provide up to 1.0 A or 1.5 A of continuous current. - GLF1800 comes in an SOT23-5L package. - GLF1800T/AT comes in a WLCSP package for tighter layouts. - The GLF1800AT EN pin includes an internal pull-up resistor tied to VIN. - The series integrates reverse-current blocking, inrush control and seamless power-source switching. - GLF says the combination is designed to simplify power-path design and improve system safety, efficiency and long-term reliability. - Pricing listed on DigiKey is $0.369 for GLF1800 in 1,000-piece quantities and $0.399 for GLF1800T/AT in 1,000-piece quantities. - Samples are in stock in Santa Clara. - Production quantities carry a 14- to 16-week lead time. - More information is available in the company's announcement or by emailing info@glfipower.com.

Between the lines: - The launch fits a broader push to squeeze more runtime from compact electronics without adding thermal complexity. - Package choice appears to be a key part of the pitch, with one version aimed at standard layouts and another aimed at space-constrained designs. - The emphasis on ultra-low current suggests the strongest appeal is in always-on devices where standby drain matters as much as active power use.

What's next: - Designers can request samples now. - Customers looking to build in volume will need to plan around the 14- to 16-week production lead time. - GLF is positioning the series for adoption in wearables and other low-voltage consumer and industrial devices.

The bottom line: - GLF is betting that a smaller, cooler ideal diode can win socket share in battery-powered systems where every millivolt and microamp counts.
