ESD5Z2.5T1G Ultra-Low Voltage TVS Diode / ESD Protection (2.5V, SOD-523)

Safeguard sensitive low-voltage digital rails and high-speed ICs with the ESD5Z52.5T1G Transient Voltage Suppressor (TVS) diode. Modern microprocessors, FPGAs, ASICs, and memory modules often operate on sub-3.3V logic rails (such as 1.8V or 2.5V). Generic 5V ESD diodes have a clamping threshold that is far too high to protect these delicate low-voltage inputs. Featuring a 2.5V reverse standoff voltage ($V_{RWM}$) and a breakdown threshold around 4V ($V_{BR}$), this specialized single-line ESD diode engages rapidly to clamp dangerous voltage transients before they can damage low-power semiconductors.

Housed in an ultra-compact SOD-523 (SC-79) surface-mount package, it requires minimal PCB footprint, making it ideal for high-density board designs. Whether you are routing sensitive sensor signals, low-voltage control lines, or power pins on advanced IoT modules and wearables, this diode provides robust electrostatic discharge protection (compliant with IEC 61000-4-2) directly where it is needed most.

Key Features:

• Sub-3.3V Logic Protection: Specifically designed for 1.8V and 2.5V digital power rails and signal lines where standard 3.3V/5V TVS diodes trigger too late.

• Fast Clamping: Neutalizes high-voltage static discharges instantly, protecting sensitive core logic in FPGAs, MCUs, and memory ICs.

• Ultra-Compact SOD-523 Package: Minimizes PCB area, allowing protection components to be placed right next to vulnerable connector pins or IC inputs.

• Single-Line Shielding: Simplifies localized board protection for individual critical signal traces or low-voltage power pins.
