STMicroelectronics TVS Diode 1-Element Bi-Directional 400 W Surface Mount, DO-214 SMAJ188CA-TR

STMicroelectronics SMAJ188CA-TR is a 1-element bi-directional transient voltage suppressor (TVS) diode delivering 400 W peak pulse power dissipation in a surface mount DO-214 package. This TVS diode is designed to protect sensitive electronic components from voltage transients and surges caused by inductive loads, switching, and lightning events.

The device features a minimum breakdown voltage of 209 V with a maximum reverse stand-off voltage of 188 V, combined with a clamping voltage of 388 V to effectively suppress transient voltages. It operates reliably over a wide temperature range from -55°C to 150°C, supporting demanding industrial, electronic components, and power connector applications.

Measuring 4.6 mm in length, 2.9 mm in width, and 2.45 mm in height, the SMAJ188CA-TR has a compact DO-214 package with 2 pins for surface mount technology (SMT) use. It supports a maximum peak pulse current of 6 A and has a test current rating of 1 mA, with a low maximum reverse leakage current of 1 μA to ensure minimal power loss during steady-state operation.

This single-element device is part of the SMAJxxCA series from STMicroelectronics, widely used in electronic circuitry requiring transient voltage protection such as industrial machinery control, automotive electronics (non-automotive standard), power supplies, and communication systems.

The product is suitable for industrial, manufacturing, electronic assembly, and power protection use cases where reliable transient voltage suppression is critical to system integrity and longevity.
