Product Description
STMicroelectronics SMAJ30CA-TR is a high-reliability 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed for surface mounting on PCBs in a compact DO-214 package. This device offers a peak pulse power dissipation of 400 W and is suitable for protecting sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD) events in industrial, automotive, and consumer electronics applications.
The diode configuration is single element, providing effective bidirectional voltage clamping capability with a minimum breakdown voltage of 33.3 V and a maximum reverse standoff voltage of 30 V. With a clamping voltage of 64.3 V and a peak pulse current of 36 A, it ensures transient overvoltages are absorbed efficiently, helping to maintain the integrity of critical components.
This TVS diode features low leakage current typically limited to 200 nA, minimizing standby power consumption. It operates reliably across a wide temperature range from -55°C to 150°C, making it ideal for harsh environments. The small DO-214 package footprint (4.6 mm length × 2.95 mm width × 2.03 mm height) supports dense PCB layouts.
The SMAJ30CA-TR series is widely used for transient and ESD protection in applications such as industrial control systems, power supplies, automotive electronics, and communication equipment. Its high surge current capacity and robust construction ensure long-lasting protection against transient voltage damages.
This product does not carry automotive-specific standards but meets general semiconductor quality demands for transient suppression applications. It is supplied on reels ready for automated assembly lines, enabling efficient mass production and improved manufacturing throughput.
Single diode configuration with bi-directional transient voltage suppression. 400 W peak pulse power dissipation in a compact surface mount package. Clamping voltage rating of 64.3 V for effective overvoltage protection.
