Product Description
Taiwan Semiconductor SMAJ51CA R3 is a single element bi-directional transient voltage suppressor (TVS) diode designed for protecting electronic circuits from voltage surges. It is rated for 400W peak pulse power dissipation and comes in a compact DO-214 surface mount package with 2 pins. The device operates within a wide temperature range of -55°C to 150°C, making it suitable for various industrial, electronic, and power management applications.
This TVS diode has a minimum breakdown voltage (Vbr) of 56.7 volts and a maximum reverse stand-off voltage (Vwm) of 51 volts, providing effective suppression of transient surges and voltage spikes. The clamping voltage (Vc) of 82.4 volts ensures that transient voltages are limited to safe levels to protect sensitive components. With a low maximum reverse leakage current of 5 microamperes, it minimizes power loss during normal operation.
The SMAJ51CA R3 model features electrostatic discharge (ESD) protection and is designed for use in surface mount technology (SMT) applications, making it ideal for use in PCB-level protection in industrial, electronic, laboratory, and commercial systems.
Single element bi-directional TVS diode configuration for transient voltage protection. Peak pulse power dissipation of 400W ensures robust surge handling capability. Surface mount DO-214 package facilitates compact PCB designs.
Wide operating temperature range from -55°C to 150°C supports harsh environments. 2-pin design simplifies integration into electronic circuits. Low leakage current and high ESD protection enhance reliability.
This diode is widely applicable in industrial electronics, power supplies, telecommunications equipment, automotive electronics (non-automotive standard), and other semiconductor devices requiring overvoltage protection.
