Product Description
Littelfuse SMBJ30CA is a 1-element bi-directional transient voltage suppressor (TVS) diode designed for surface mount applications. It provides a peak pulse power dissipation of 600 watts in a compact 2-pin DO-214AA (SMB) package, making it suitable for protecting sensitive electronic circuits from transient voltage spikes caused by inductive load switching and lightning strikes.
This TVS Diode features a minimum breakdown voltage of 33.3V and a maximum reverse standoff voltage of 30V, with a clamping voltage of 48.4V to safely dissipate transient energy. Its maximum peak pulse current rating is 12.4A, and the device operates reliably in a wide temperature range from -65°C to 150°C, making it ideal for harsh industrial environments.
The low maximum reverse leakage current of 1 microampere reduces power loss during normal operation. The SMBJ30CA consists of a single element per chip with bi-directional configuration, offering symmetrical voltage protection for AC and DC lines. The compact size of 4.57mm by 3.94mm by 2.237mm supports high-density PCB layouts.
Common applications include use in power supplies, telecommunications, automotive electronics (non-automotive standard part), and general industrial electronic protection circuits. It is well suited for transient voltage protection in electronic control devices, industrial equipment, and instrumentation.
Provides 600W peak pulse power dissipation for transient voltage protection. Supports bi-directional operation to protect AC and DC lines. Surface mount DO-214AA (SMB) package with 2 pins for easy PCB integration. Wide operating temperature range from -65°C to 150°C.
Low reverse leakage current minimizes standby power consumption. Compact dimensions enable space-efficient circuit designs. Reliable clamping voltage of 48.4V to protect downstream components. Single element design improves response time and protection efficiency.
Suitable for industrial, telecommunications, and power supply applications. Complies with industry standards for quality and performance, excluding automotive standards.
