1SMA5921_R1_00001 Description

Short technical summary and product information.

The 1SMA5921_R1_00001 is a 6.8V surface mount Zener diode from PANJIT, part of the 1SMA5921 series. It features a nominal Zener voltage of 6.8V with ±5% tolerance, and a maximum power dissipation of 1.5W when mounted on specified land areas. The device offers low impedance of 3Ω at a test current of 55.1mA, and a maximum Zener impedance of 200Ω at 1mA.

 

This Zener diode is designed for general purpose voltage regulation and protection circuits in surface mount applications. It is housed in a JEDEC DO-214AC (SMA) molded plastic package with solder plated terminals, compatible with standard reflow soldering processes. The operating junction temperature range is -55°C to 150°C, with a peak forward surge current rating of 10A.

 

The component is RoHS3 compliant and uses a green molding compound as per IEC 61249. Typical applications include voltage clamping, reference voltage sources, and overvoltage protection in compact electronic assemblies.
