The SMA4F188A from STMicroelectronics is a robust transient voltage suppressor (TVS) designed to protect sensitive electronics from voltage spikes and transients induced by lightning and other transient voltage events. This component is an essential safeguard for circuits that require high reliability and protection in harsh environments.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 188V, making it suitable for a range of applications that require a high stand-off voltage to ensure protection.
• Peak Pulse Power: It can handle a peak pulse power of 400W (10/1000μs), providing robust protection against surges and power spikes.
• Low Clamping Voltage: The SMA4F188A has a low clamping voltage, which ensures that the voltage to which the protected components are exposed during a transient event is minimized.
• Fast Response Time: With a response time typically less than 1 picosecond from 0V to BV min, it offers quick protection for sensitive circuits.
• Package: Housed in an SMA flat, a compact package that is ideal for automated assembly and offers a low profile when mounted on a printed circuit board.
