STMicroelectronics Bi-Directional TVS Diode 230V 2-Pin DO-214 Surface Mount SMP100LC-230

STMicroelectronics SMP100LC-230 Bi-Directional TVS Diode, operating at 230V, is designed to provide robust protection against transient voltage surges in sensitive electronic circuits. The device features a 2-pin DO-214 surface mount package, ideal for compact PCB layouts and modern electronic assemblies.

This diode offers bi-directional crowbar protection for high data rate communication equipment, ensuring signal integrity even under surge conditions. With a minimum breakdown voltage of 230V and a maximum reverse stand-off voltage of 207V, it provides reliable voltage clamping across both polarities. The SMP100LC-230 delivers a high peak pulse current capability of up to 150A, making it suitable for demanding surge protection scenarios such as telecom systems and industrial control lines.

Engineered with low capacitance (20 pF to 45 pF at 2 V), the TVS diode avoids distortion of digital signals, ensuring compatibility with advanced line cards including xDSL and ISDN. Its low leakage current, rated IR ≤ 2 μA, and holding current of IH ≥ 150 mA, further contribute to safe, reliable circuit protection. Operating temperature spans −40°C to +150°C, supporting deployment in varied environmental conditions.

With a single element per chip, surface mount format, and compact dimensions (length 4.6 mm, width 2.2 mm, height 2.45 mm), this diode is optimized for high-density electronic applications. ESD protection is built-in, enhancing resilience against static discharge in telecom and communication interfaces.

The SMP100LC-230 series is compatible with Eaton Telecom Circuit Protector TCP 1.25A, providing flexibility in professional surge protection setups. It is not subject to ageing, thanks to its designed fail-safe mode in short circuit scenarios, maximizing circuit safety over the lifetime of the equipment.

Industrial and commercial use cases include protection for digital transmission lines, telecom infrastructure, manufacturing equipment, instrumentation, and sensitive electronics exposed to voltage transients. This diode is a critical component for maintaining reliability and safeguarding communication, data, and power circuits from harmful surges or ESD events.
