onsemi ESD9R3.3ST5G is a high-performance 1-element uni-directional transient voltage suppression (TVS) diode engineered to protect sensitive electronic components against voltage spikes and electrostatic discharge (ESD) events. With a peak pulse power dissipation rating of 0.15 W and housed in a compact 2-pin SOD-923 surface mount package, this diode provides robust and reliable circuit protection in a minimal footprint.
Designed for industrial, automotive, and electronic applications requiring efficient ESD protection, the diode features a minimum breakdown voltage (Vbr) of 4.8 V and a maximum reverse stand-off voltage (Vwm) of 3.3 V. It efficiently clamps dangerous voltage transients to a safe level of 7.8 V, ensuring downstream electronics remain safe during surge events.
The device operates effectively across a wide temperature range from -55°C to 125°C, complying with the stringent AEC-Q101 automotive qualification standard, making it suitable for automotive and harsh-environment applications. Low leakage current of 1 nA minimizes power losses, enhancing overall system efficiency.
The diode's precise 1 mA test current and 1 A peak pulse current capability deliver reliable protection against sudden current surges. Its small dimensions (0.85 mm length, 0.65 mm width, and 0.4 mm height) enable dense PCB layouts and seamless integration into compact designs.
Single element diode configuration offers focused and effective ESD defense. Uni-directional current flow designed to protect against positive voltage surges. Surface mount SOD-923 package facilitates automated assembly and compact design.
Comprehensive automotive standard compliance ensures reliability in vehicle electronics. Low capacitance and leakage support high-speed signal integrity.
This TVS diode from onsemi is ideal for use in automotive electronics, consumer devices, telecommunications equipment, and industrial control systems where stringent ESD protection is required without compromising circuit size or performance.
