Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 400W Surface Mount DO-214 SMAJ45CA R3

Taiwan Semiconductor SMAJ45CA R3 is a 1-element bi-directional transient voltage suppressor (TVS) diode designed for surface mount applications in electronic circuits. It provides robust protection against voltage spikes up to 400 watts, safeguarding sensitive semiconductor components from damage caused by transient overvoltages.

This TVS diode is housed in a compact DO-214 surface mount package with precise dimensions measuring 4.6 mm in length, 2.83 mm in width, and 2.3 mm in height, facilitating efficient PCB designs in compact assemblies.

Key electrical characteristics include a minimum breakdown voltage (Vbr) of 50 volts, a maximum reverse stand-off voltage (Vwm) of 45 volts, and a clamping voltage (Vc) of 72.7 volts. The device supports a maximum peak pulse current (Ippm) of 5.5 amperes and features a maximum reverse leakage current of 5 microamperes, ensuring minimal power dissipation during normal operation.

Operating reliably within the temperature range from -55°C to 150°C, this diode is suitable for various industrial and commercial electronics, providing transient voltage suppression in power supplies, communication devices, and control circuitry. It does not meet automotive standards but excels in general semiconductor protection tasks.

The single diode element configuration and 2-pin design simplify mounting and ensure effective ESD protection on sensitive lines. Test current is rated at 1 mA to validate device operation under defined conditions.
