STMicroelectronics 1-Element Bi-Directional TVS Diode 3 kW 2-Pin Surface Mount DO-214 SM30T28CAY

STMicroelectronics SM30T28CAY is a single-element, bi-directional transient voltage suppression (TVS) diode with a peak pulse power dissipation rating of 3 kW. Packaged in a compact 2-pin DO-214 surface mount package, it offers robust voltage protection for sensitive electronic components and circuits.

This device features a minimum breakdown voltage (Vbr) of 26.7 V and a maximum reverse stand-off voltage (Vwm) of 24 V, making it suitable for suppressing transient overvoltages in a wide range of electronic and industrial systems. Its clamping voltage (VC) of 43.9 V ensures a rapid voltage clamp during transient events to protect downstream components from damage.

The diode supports a maximum peak pulse current (Ippm) of 630 A and maintains excellent low leakage characteristics with a maximum reverse leakage current of 200 nA. It can operate reliably within temperatures from -55°C to 150°C, suitable for harsh industrial and automotive environments. The device also complies with the AEC-Q101 automotive standard, demonstrating its suitability for automotive electronics and systems exposed to fluctuating electrical conditions.

Its compact dimensions of 7.15 mm length, 6.25 mm width, and 2.45 mm height facilitate easy surface mounting on printed circuit boards, allowing for space saving in system designs. This diode is optimized for transient voltage suppression in power supplies, industrial control systems, communication equipment, and automotive electronic modules.

Applications typically include protection against electrostatic discharge (ESD), inductive load switching surges, and lightning transient events in sensitive equipment. The SM30T28CAY is designed to enhance system reliability by absorbing transient energy and preventing component failure.
