Product Description
STMicroelectronics SMAJ170CA-TR is a 1-element bi-directional transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage surges and transient spikes. This TVS diode supports a peak pulse power dissipation of 400W, making it suitable for use in industrial and commercial electronic equipment requiring robust protection against high energy transient events.
The device is housed in a compact 2-pin DO-214 surface mount package with dimensions 4.6mm in length, 2.9mm in width, and 2.45mm in height. Its single diode configuration provides bi-directional voltage suppression, enabling protection against both positive and negative voltage spikes.
The SMAJ170CA-TR offers a minimum breakdown voltage of 189V and a maximum reverse stand-off voltage of 170V, ensuring the component only responds during transient voltage events above normal operation levels. The clamping voltage at 353V effectively limits peak transient voltages to safe levels, protecting connected circuitry.
This TVS diode can withstand a peak pulse current of 6.5A and features a minimal reverse leakage current of 1µA, which contributes to overall energy efficiency. Its operating temperature range extends from -55°C to 150°C, allowing reliable use in various harsh environment applications.
Applications include surge protection in industrial control systems, consumer electronics, automotive electronics, and telecommunications equipment. This diode provides critical protection for power lines, data lines, and signal lines against transient voltage threats, increasing system reliability.
