Product Description
Littelfuse SMCJ48A is a high-performance 1-Element Uni-Directional TVS Diode designed to offer reliable transient voltage suppression in electronic circuits, rated at 1.5 kW peak pulse power with a 2-pin DO-214 surface mount package.
This device provides effective protection against voltage surges by maintaining a maximum reverse stand-off voltage of 48 V and a minimum breakdown voltage of 53 V, ensuring circuits stay safe during transient events.
It features a clamping voltage of 77.4 V which clamps transient voltages safely, protecting downstream components. The SMCJ48A supports high peak pulse current up to 19.4 A along with electrostatic discharge (ESD) protection for enhanced durability.
Built for harsh environments, this diode operates reliably between -65°C and 150°C. It has a compact footprint with dimensions 7.11 mm in length, 6.22 mm in width, and 2.417 mm in height, making it suitable for surface mount technology (SMT) applications on PCB assemblies.
Featuring a single diode element and uni-directional conduction, the device is ideal for protecting power supply lines, industrial electronics, automotive electronics (non-automotive certified), manufacturing equipment, and consumer electronic circuits from damaging voltage transients.
The diode configuration is single, with a peak reverse leakage current of 1 μA which ensures very low power loss during normal operation. The SMCJ48A series is widely used in industrial, laboratory, and commercial electronics for durable, high-impact transient voltage protection.
Maximum reverse stand-off voltage: 48 V. Minimum breakdown voltage: 53 V. Peak pulse power dissipation: 1.5 kW. Clamping voltage: 77.4 V. Peak pulse current: 19.4 A. Operating temperature range: -65°C to 150°C. Package type: DO-214 surface mount.
Pin count: 2. Diode configuration: Single element, uni-directional. Maximum reverse leakage current: 1 μA.
Littelfuse SMCJ48A ensures robust electrostatic and transient voltage protection in electronics, suitable for industrial, laboratory, manufacturing, and commercial applications. Explore more TVS Diode solutions on EnvMart for comprehensive voltage protection needs.
