Founded in 1994 by a team of seasoned diode engineers and venture capitalists, ZOWIE Technology Co., Ltd. is a leading designer and manufacturer of advanced discrete semiconductor products. Driven by the vision of creating the “next generation of diodes,” ZOWIE has consistently innovated in the field of silicon semiconductor technology, particularly for low- and medium-power rectifiers. Our mission is not only to rebuild Taiwan’s R&D and manufacturing capabilities but also to foster the growth of its diode industry, ultimately contributing to technological progress and the well-being of humanity.
Pioneering Diode Innovation
ZOWIE’s journey began with four years of intensive R&D, culminating in the successful development of the Glass Passivated Rectifier Chip (GPRC). After initial trials in 1995, the GPRC was officially launched in 1998, setting a new standard for performance, reliability, and durability in the semiconductor industry.
In 2001, ZOWIE introduced the SuperChip Diode (SCD)—the world’s first chip-type diode. This compact, high-efficiency SMD device revolutionized power rectification by offering superior thermal performance and space-saving advantages, ideal for modern electronics requiring miniaturization without compromising power.
Global Recognition & Patent Achievements
With over 30 international patents across Taiwan, the U.S., Mainland China, Japan, and the UK, ZOWIE has cemented its place as a global technology innovator. These patents protect ZOWIE’s unique designs, materials, and packaging methods—each engineered for optimal performance, reliability, and scalability across various industries.

Technological Advantages
ZOWIE products are known for:
-
High thermal resistance (Tj up to 175°C)
-
Low leakage current (IR ~0.1 µA)
-
Ultra-miniature packaging (SMD)
-
Superior heat dissipation
-
Lead-free and halogen-free compliance (RoHS)
-
High reliability in automotive, medical, and industrial applications
Our GPRC diodes feature full glass encapsulation directly on the P/N junction, delivering unmatched heat resistance and reliability.
