PANJIT’s PS2112-D33 is a high-performance, ultra-compact ESD protection diode designed to safeguard next-generation ultra-high-speed interfaces such as 80G/120G bandwidth channels. Featuring a working voltage as low as 1.5V, this device is housed in a DFN0603-3L (0.6 × 0.3 × 0.3 mm) package with dual-channel protection (Pin 1 and Pin 3 to Pin 2 as ground), enabling space-saving layout and reducing the total number of required components.

A standout innovation is PANJIT’s proprietary die isolation technology, which effectively eliminates internal cross-talk—an issue common in compact dual-channel ESD devices. This allows PS2112-D33 to maintain signal integrity in tight layouts without compromising performance. Additionally, its ultra-low junction capacitance of 0.13 pF and excellent insertion loss performance (−0.44 dB @15 GHz) ensure minimal signal distortion, making it ideal for differential high-speed signal lines.

Engineered to meet IEC61000-4-2 ESD standards (±11kV Contact / ±13kV Air) and IEC61000-4-5 surge protection (4A, 8/20 μs), the PS2112-D33 combines low clamping voltage, low leakage current, and Pb-free/RoHS-compliant construction to support reliable and sustainable system design.
