SMA6F170A Description

Short technical summary and product information.

The SMA6F170A from STMicroelectronics is a unidirectional TVS Diode designed to protect sensitive circuits from transient surges. It operates within a wide temperature range of -55°C to 175°C and offers a peak pulse power dissipation of 600W (10/1000 µs).

 

This device features a stand-off voltage of 170V and a clamping voltage of 275V at a peak pulse current of 2.2A. The low leakage current of 0.2 μA at 25°C and 1 μA at 85°C makes it suitable for high-end circuits requiring long-term reliability and stability. The planar technology enhances its performance characteristics.

 

The SMA6F170A is available in a surface mount DO-221AC, SMA Flat Leads package (SMAflat). It complies with various standards including UL94 V0 and J-STD-020 MSL level 1. The lead finishing is matte tin plating.

 

This TVS diode is suitable for general purpose applications where transient voltage suppression is required. Its robust design and high power capability ensure effective protection against voltage spikes.
