WPExxxD3ULA
Bidirectional Ultralow Capacitance TVS ARRAY
WPE3V3D3ULA, WPE5V0D3ULA, WPE8V0D3ULA,
WPE12VD3ULA, WPE15VD3ULA, WPE24VD3ULA
Bidirectional Ultralow Capacitance TVS ARRAY
The WPExxxD3ULA is ultra low capacitance transient voltage suppressor arrays, designed to protect applications such
as portable electronics and SMART phones. This series is available in both unidirectional and bidirectional configurations
and is rated at 350 Watts for an 8/20μs waveform.
The WPExxxD3ULA meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) requirements. At higher operating
frequencies or faster edge rates, insertion loss and signal integrity are a major concern. This series offers an ultra low
capacitance and low leakage current in a miniature SOD-323 package.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
*Other voltages may be available upon request.
