STMicroelectronics 4-Element Uni-Directional TVS Diode, 25 W, 5-Pin SOT-323 ESDALC6V1W5

STMicroelectronics ESDALC6V1W5 is a high-performance, 4-element uni-directional TVS (Transient Voltage Suppressor) diode engineered for optimal electrostatic discharge (ESD) protection in electronic assemblies. With a peak pulse power dissipation of 25 W, this device acts as a critical safeguard against voltage spikes and transient events, preserving the integrity of sensitive circuit components.

Featuring a common anode configuration and encapsulated in a small SOT-323 surface-mount package, the ESDALC6V1W5 is designed for efficient integration on printed circuit boards, minimizing footprint and supporting automated production processes. The compact five-pin form factor ensures ease of installation in space-constrained designs, making it ideal for both consumer and industrial applications.

Thanks to its uni-directional protection scheme, the diode responds rapidly to electrical surges, maintaining functional stability and providing reassurance across a broad operating temperature range of -40°C to 150°C. The integrated ESD protection capability extends device life and reliability, particularly in environments prone to static discharge and transients.

This TVS diode's four-element array supports enhanced protection coverage for multi-line signals or interconnected circuitry. It achieves a minimum breakdown voltage of 6.1 V and a maximum reverse stand-off voltage of 3 V, ensuring reliable isolation and suppression when voltage anomalies occur.

The ESDALC6V1W5 series is part of STMicroelectronics’ ESDA product family, well-regarded in industrial, commercial, and consumer electronics for safeguarding microcontrollers, communication interfaces, and sensor inputs. Its low leakage current (1 μA max) and compliance with SOT-323 package standards ensure compatibility and efficient deployment in modern electronic assemblies.

Suitable use cases include circuit protection in industrial automation, laboratory instrumentation, communication routers, consumer electronics, and automotive interfaces that require stringent ESD management. The device is not certified for automotive standards, making it preferable for non-automotive environments.
