Product Description
Bourns SMAJ30CA is a single-element bi-directional Transient Voltage Suppressor (TVS) diode designed for transient voltage spike protection in electronic circuits. This TVS Diode package type is DO-214 AB (SMB), surface-mountable for efficient PCB integration.
Rated at 400 watts peak pulse power dissipation, it is capable of handling significant voltage surges with a minimum breakdown voltage (Vbr) of 33.3 volts and a maximum reverse stand-off voltage (Vwm) of 30 volts. The diode clamps voltage spikes at 48.4 volts (VC) protecting circuits from damage.
With a test current of 1 mA and a maximum peak pulse current (Ippm) of 8.3 A, this component is suitable for industrial, automotive, and consumer electronics applications requiring robust voltage transient suppression. It operates reliably across a wide temperature range from -65°C up to 150°C and meets the automotive standard AEC-Q101, making it ideal for automotive electronics protection.
The compact dimensions of 4.5 mm length, 2.92 mm width, and 2.087 mm height enable dense design layouts. It has a low maximum reverse leakage current of 1 μA, minimizing power loss during normal operation.
Its bidirectional configuration allows it to protect circuits from both positive and negative transient voltages, making it versatile in various power and signal line protections. The component is RoHS-compliant and manufactured in Taiwan, Province Of China.
Applications include industrial electronics, automotive systems, power supplies, consumer electronics, and telecommunications equipment. The reliable transient voltage suppression improves the durability and reliability of sensitive electronic devices.
