Product Description
STMicroelectronics SMAJ5.0A-TR is a 1-element uni-directional transient voltage suppression (TVS) diode engineered for protecting sensitive electronic circuits from voltage spikes and surges. Rated at a peak pulse power dissipation of 400 W and packaged in a compact 2-pin DO-214 surface mount type, this diode offers robust transient voltage protection in a small footprint.
The device has a minimum breakdown voltage of 6.4 V and a maximum reverse stand-off voltage of 5 V, effectively clamping transient voltages with a clamping voltage rating of 13.4 V. Its single-element chip design ensures accurate and reliable voltage suppression performance.
With a test current of 10 mA and a maximum peak pulse current of 174 A, the SMAJ5.0A-TR diode is capable of handling extreme transient conditions, making it suited for industrial and commercial electronic applications. The diode supports a broad operating temperature range from -55°C to 150°C to maintain functionality in harsh environments.
Its low reverse leakage current of 20 μA contributes to minimized power loss and enhanced energy efficiency, while the device’s surface mountable DO-214 package facilitates automated assembly and space-saving PCB layouts.
This TVS Diode is compliant with standard commercial semiconductor design but does not carry specific approvals or automotive standards, though its robust specifications render it suitable for a wide variety of applications including power supplies, communication equipment, and general electronic circuit protection.
