SMC30J40CA Transient Voltage Suppressor

The SMC30J40CA is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This high-performance device is specifically engineered to safeguard circuits against the damaging effects of overvoltage transients, providing a reliable shield for integrated circuits, transistors, and other components in a variety of applications.

Key Features

• Stand-off Voltage: The SMC30J40CA has a stand-off voltage of 40V, which makes it suitable for a wide range of applications where this voltage level is prevalent.
• Peak Pulse Power: It can handle a peak pulse power of 3000W (10/1000μs), ensuring effective protection against high energy transients.
• Clamping Voltage: With a low clamping voltage, the device provides an immediate response to transient overvoltages, thereby limiting the voltage that is passed through to the protected component.
• Bi-directional Device: The SMC30J40CA is a bi-directional TVS, meaning it can provide protection in both forward and reverse directions, which is ideal for AC applications or where the polarity is undefined.
• Package: Supplied in an SMC (DO-214AB) package, the device is compact and suitable for high-density board installations.
• Compliance: It meets the MSL level 1 standard, per J-STD-020, and is RoHS compliant, ensuring it meets current environmental standards for electronic components.
