1N5385B datasheet

Description :

The 1N5385B is 170V, 5W, Zener Diode.

The 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners provides a selection from 3.3 to 200 volts with different tolerances as identified by specific suffix letter on the part number.

These plastic encapsulated Zeners have a moisture classification of “Level 1” with no dry pack required. They may be operated at high maximum dc currents with adequate heat sinking due to their comparatively low thermal resistance design. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

SMBJ160 datasheet

Description :

This SMBJ5.0-170A or SMBG5.0-170A series of surface mount 600 W Transient Voltage Suppressors (TVSs) protects a variety of voltage-sensitive components from destruction or degradation.

It is available in J-bend design (SMBJ) with the DO-214AA package for greater PC board mounting density or in a Gull-wing design (SMBG) in the DO-215AA for visible solder connections.

It is also available in both unidirectional and bidirectional configurations with a C or CA suffix part number as well as RoHS Compliant with an e3 suffix.


1. Underwriters Laboratory recognition under UL standard for safety 497B : Isolated loop curcuit protection
2. Low profile package with built-in strain relief for surface mounted applications
3. Glass passivated junction
4. Low incremental surge resistance, excellent clamping capability
