Product Description
STMicroelectronics SMCJ18CA-TR is a high-performance 1.18 V bi-directional Zener diode supplied in a compact DO-214AB (SMC) surface mount package with two pins. It integrates a single diode element designed to provide reliable transient voltage suppression for sensitive semiconductor devices, making it ideal for industrial electronic applications, including power and signal line protection.
This diode features a peak pulse power dissipation of 1500 W at 10/1000 μs surge and 10 kW at 8/20 μs surge, offering robust protection against sudden high-energy spikes such as electrostatic discharges and electrical over stress events. The device's low leakage current at operating temperatures enhances the reliability and extends the operational lifespan of protected equipment.
The product operates robustly within a wide temperature range from -55°C minimum to 150°C maximum junction temperature, accommodating challenging industrial and commercial environments while maintaining stable voltage clamping characteristics. Its standoff voltage range from 5 V up to 188 V makes it suitable for various circuit designs, including automotive, industrial controls, telecommunications, and consumer electronics.
The planar technology used in SMCJ18CA-TR ensures compatibility with high-end equipment and switched-mode power supplies (SMPS). This diode's bi-directional construction allows it to protect circuits from forward and reverse voltage transients, enhancing versatility in diverse protection schemes.
