Product Description
Littelfuse SMAJ5.0A is a high-performance, uni-directional transient voltage suppressor (TVS) diode designed to protect electronic circuits from voltage spikes and transient surges. The device’s single-element configuration provides quick response to sudden voltage transients, effectively clamping voltage spikes to safe levels and preventing damage to sensitive components.
Encapsulated in a compact 2-pin DO-214 surface mount package, this diode offers a peak pulse power dissipation of 400 W, making it suitable for protecting power lines and signal lines in industrial, consumer electronics, automotive, and telecommunication applications.
With a minimum breakdown voltage of 6.4 V, maximum reverse stand-off voltage of 5 V, and a clamping voltage of 9.2 V, the SMAJ5.0A effectively limits transient voltages, maintaining system stability. The device withstands peak pulse currents up to 43.5 A and can operate across a wide temperature range from -65°C to 150°C, ensuring reliable performance in harsh environmental conditions.
The diode’s dimensions are optimized for space saving with a height of 2.087 mm, length of 4.5 mm, and width of 2.79 mm. Its low maximum reverse leakage current of 800 μA reduces power loss during normal operation, and its ESD protection feature adds an extra layer of defense against electrostatic discharge hazards.
This Littelfuse SMAJ5.0A TVS diode finds applications in circuit protection for industrial machinery, power supplies, automotive electronics, telecommunications infrastructure, and consumer electronic devices where safeguarding against voltage transients is critical.
This is a Uni-Directional 1-Element TVS Diode with 400 W peak pulse power rating. Package is 2-Pin DO-214 for surface mounting. Voltage ratings include 5 V maximum reverse stand-off and 6.4 V minimum breakdown voltage. Operating temperature range is from -65°C to 150°C.
Includes Electrostatic Discharge (ESD) protection. Compact dimensions provide ease of PCB layout integration. Suitable for industrial, automotive, and consumer electronics protection. Littelfuse SMAJ series compliance ensures quality and performance.
