The DiodesZetex SD09C-7 is a compact, high-efficiency bi-directional TVS (Transient Voltage Suppression) diode, specifically engineered to offer exceptional protection for sensitive electronic circuits exposed to electrostatic discharge (ESD) and high-surge events. With a peak pulse power capability of 400 W, this diode is widely adopted in modern electronic systems where robust, compact circuit protection is mandatory.
This single-element diode is designed with a 2-pin SOD-323 surface-mount package, making it ideal for densely populated PCBs, especially in portable consumer and professional applications. Its bi-directional clamping allows it to absorb voltage surges and protect both signal and power lines irrespective of polarity, making it versatile for a broad range of designs.
Technical specifications include a minimum breakdown voltage of 10 V and a reverse stand-off voltage of 9 V. The SD09C-7 supports a maximum peak pulse current of 20 A and clamps voltage spikes to 20 V. With a low maximum reverse leakage current of just 1 μA, as well as ultra-low channel input capacitance, it ensures high data signal integrity while providing continuous ESD protection.
This diode meets stringent industry immunity standards, including IEC 61000-4-2 for ESD, and carries automotive-grade reliability with AEC-Q101, AEC-Q200, and AEC-Q100 compliance. The operating temperature range spans from −65°C to 150°C, supporting usage in both consumer and demanding industrial or automotive environments.
Practical use cases include circuit protection for mobile phones, digital cameras, MP3 players, and diverse portable electronic equipment where reliable surge and ESD defense are critical. The SD09C-7 offers ideal performance in environments where PCB space must be minimized without compromising on protection requirements.
Dimensions are tightly controlled, with a component length of 2.7 mm, width of 1.1 mm, and height of 1.4 mm, aligning with modern miniaturization demands. The device is RoHS compliant and built to high-quality DiodesZetex standards.
