STMicroelectronics SMA4F58A 1-Element Uni-Directional TVS Diode delivers transient voltage suppression with a peak pulse power dissipation rating of 400 W. It is designed as a single element device with uni-directional diode configuration for effective protection of sensitive electronic components from voltage spikes.
The device comes in a surface mount SMA flat package, enabling easy integration on printed circuit boards suited for automotive, industrial, and consumer electronics applications. It operates efficiently within a temperature range from -55°C minimum to 175°C maximum, ensuring long-term reliability under demanding environmental conditions.
Key electrical parameters include a minimum breakdown voltage of 71.4 V, a maximum reverse stand-off voltage of 58 V, and a clamping voltage of 93.6 V. Its maximum peak pulse current is rated at 4.3 A with a very low leakage current of 1 μA, which minimizes power loss and interference.
The diode utilizes planar technology with matte tin plating finish on leads to ensure superior durability and stability in high end electrical circuits requiring low leakage current and high junction temperature tolerance.
Minimum breakdown voltage of 71.4 V caters to typical transient voltage requirements. Surface mount SMA flat package allows for compact PCB layout. High peak pulse power dissipation of 400 W for reliable surge protection.
Low leakage current of 1 μA enhances circuit stability. Wide operational temperature range from -55°C to 175°C provides robustness. Compact physical dimensions facilitate high-density electronic assembly. Ideal for industrial, automotive, and consumer electronics transient suppression applications.
This TVS diode is a vital component for any transient voltage suppression need in electrical and electronic circuits, helping protect diagnostic, measurement, power, and communication equipment against voltage spikes.
