SMBG5913 – SMBG5956e3,
SMBJ5913 – SMBJ5956e3
Available Silicon 2.0 Watt Zener Diodes
DESCRIPTION
The SMB(G/J)5913B – SMB(G/J)5956B series of surface mount 2.0 watt Zener diodes
provides a selection from 3.3 to 200 volts with tolerance options of 10%, 5% and 2%. This
series has the same electrical characteristics as the axial, JEDEC registered 1N5913 -
1N5956 series with the exception of its higher, 2.0 W power rating (versus 1.5 W for the
JEDEC series). This is permitted by the lower thermal resistance of the surface mount
packaging. The SM BG Gull-wing design in the DO-215AA package provides for visible solder
connections. The SMBJ J-b end des ign in the DO-214AA package permits greater PC board
mounting density. The series is available with SnPb plated leaded or RoHS compliant matte-
tin plat in g.

FEATURES
• Surface mount equiv alent to JE DE C register ed 1N5913 thru 1N 5956 number series but with a 30%
higher power rating.
• Ideal for high-density and low-profile mounting.
• Zener voltage available 3.3 V to 200 V.
• Standard voltage tolerances are plus/minus 10%, 5% and 2%.
• RoHS compliant versions available.
APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range.
• Non-sensitive to ESD per MIL-STD-750 method 1020.
• Withstands high surge stresses (see figure 2).
• Minimal changes of voltage versus current.
• High specifi ed maximum current (IZM) when adequately heat sunk.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required.

NOTE 1: Zener voltage (V z) is measured at TL = 30 oC and 20 seconds after application of dc current.
NOTE 2: The Zener impedance is derived from 1 kHz ac voltage resulting from an ac current modulation having an rms value equal to 10% of the
dc Zener current (IZT or IZK) superimposed on IZT or IZK. See Mic roNote 202 for Zener impedance variation with diff erent operating
currents.
NOTE 3: The maximum dc current (IZM) is based only on the maximum power of 2.0 watts at TL < 80 oC. These values must be reduced by
37.5% (1.25 W) when mounted on PC boards as described in maximum ratings.
