Diodes Incorporated SMAJ48A-13 Product Overview

The SMAJ48A-13 is a robust surface-mount Transient Voltage Suppressor (TVS) diode designed by Diodes Incorporated to protect sensitive electronic equipment from voltage transients induced by system-level events such as load dump, lightning, and electrostatic discharge (ESD). This TVS diode is an ideal solution for the protection of I/O interfaces, VCC bus, and other vulnerable circuits used in a wide range of applications including consumer electronics, automotive, industrial, and telecommunication systems.

Key Features of SMAJ48A-13

• Peak Pulse Power Dissipation: The device can handle 400W peak pulse power dissipation for a 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Breakdown Voltage: It has a stand-off voltage of 48V, which is the maximum voltage that the diode can withstand without conducting significant current.
• Clamping Voltage: The SMAJ48A-13 has a low clamping voltage, which is the maximum voltage the device will allow to pass through after a surge has occurred, thus preventing damage to the protected component.
• Fast Response Time: The device's response time to transient events is less than 1 picosecond, offering instantaneous protection for sensitive circuits.
• Low Leakage Current: It has a low idle current (leakage current), minimizing power consumption when the device is in standby mode and not actively conducting.
• Surface Mount Package: Packaged in the SMA (DO-214AC) package, it is designed for automated assembly and is compatible with high-volume production.
• RoHS Compliant: The SMAJ48A-13 is environmentally friendly and meets the Restriction of Hazardous Substances (RoHS) directive, making it suitable for use in green products.
