Product Description
STMicroelectronics SMAJ12A-TR is a high-performance, 1-element uni-directional transient voltage suppression (TVS) diode designed specifically for surface-mount technology (SMT) applications. It is housed in a compact DO-214 package with 2 pins, making it ideal for protecting sensitive electronic circuits from voltage surges, spikes, and transient events.
This TVS diode offers a peak pulse power dissipation rating of 400 W and is designed to clamp transient voltages effectively, thereby preventing damage to downstream components. Its minimum breakdown voltage is 13.3 volts with a maximum reverse stand-off voltage of 12 volts, making it suitable for low voltage protection circuits.
The diode operates reliably in a wide temperature range of -55°C to 150°C, allowing usage in demanding industrial, automotive (non-automotive standard), telecommunications, and consumer electronic applications. The extremely low maximum reverse leakage current of 200 nanoamperes minimizes power consumption and heat generation during normal operation.
The small form factor, measuring 4.6mm long, 2.95mm wide, and 2.03mm high, enables high-density PCB layouts. The device includes ESD (Electrostatic Discharge) protection, significantly enhancing the robustness of the electronic system against electrostatic events.
Transient voltage suppression for electronics protection. 400 W peak pulse power dissipation. Uni-directional single diode configuration. Compact DO-214 surface mount package. Operating temperature from -55°C to 150°C. Low leakage current and high surge current capability.
