SMCJ48A-E3/57T Description

Short technical summary and product information.

The SMCJ48A-E3/57T is a transient voltage suppressor diode engineered for circuit protection against electrostatic discharge and fast transient events. It operates with a defined working voltage of 48 V and reaches its clamping threshold at 77.4 V. These electrical characteristics ensure that downstream components remain within safe operating limits during overvoltage conditions.

 

Designed for surface mount integration, this device utilizes the DO-214AB (SMC) package footprint. The compact form factor supports automated pick-and-place manufacturing while maintaining robust thermal dissipation capabilities. Engineers can implement this component across various power distribution lines, signal interfaces, and communication ports where rapid voltage spike mitigation is required.

 

The part number designation indicates availability in both unidirectional and bidirectional configurations, allowing flexibility for AC and DC line protection applications. Proper placement near the point of entry maximizes suppression effectiveness by minimizing parasitic inductance between the protected circuit and the diode terminals.
