SMAJ5918B-TP Description

Short technical summary and product information.

The SMAJ5918B-TP is a 5.1V Zener diode from Micro Commercial Co designed for surface-mount applications. It offers a nominal Zener voltage of 5.1V with ±5% tolerance at a test current of 73.5 mA. The device is rated for a maximum DC power dissipation of 1.5W and features a low dynamic impedance of 4 Ω at the test current, ensuring stable voltage regulation.

 

This Zener diode is housed in a DO-214AC (SMA) package with molded plastic case material rated UL 94V-0 for flammability. It supports a maximum junction temperature of 150°C and a storage temperature range of -65°C to +175°C. The thermal resistance from junction to lead is 50 °C/W. The part is RoHS compliant and has an MSL rating of 1 (unlimited).

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in power supplies and other electronic circuits. The surface-mount package enables compact PCB designs and automated assembly.
