Product Description
Littelfuse SMBJ48CA is a 1-element bi-directional transient voltage suppressor (TVS) diode designed for efficient protection of circuits against voltage spikes and transient surges. It features a maximum peak pulse power dissipation of 600 W and is configured as a single diode in a 2-pin DO-214 surface mount package.
This device provides excellent surge protection in both directions, making it ideal for sensitive electronic components in industrial, automotive, and consumer applications. It operates reliably in temperatures ranging from -65°C to 150°C, covering a broad range of operating environments.
With a minimum breakdown voltage of 53.3 V and maximum reverse stand-off voltage of 48 V, it safeguards electronics by clamping voltage spikes to a nominal 77.4 V. The maximum peak pulse current capability of 7.8 A and extremely low reverse leakage current (1 μA max) contribute to its robustness and low power loss.
Its compact DO-214 package with dimensions of approximately 4.57 mm length, 3.94 mm width, and 2.237 mm height supports high-density PCB layouts while maintaining thermal efficiency.
The SMBJ48CA complies with standard TVS diode performance requirements, though it has no specific approvals or automotive certifications. It is widely used in power supplies, telecom systems, industrial equipment, and other electronics requiring robust transient voltage suppression.
