SMBJ5913B – SMBJ5956B
Available
SILICON 2.0 Watt ZENER DIODES
DESCRIPTION
The SMBJ5913B - SMBJ5956B series of surface mount 2.0 watt Zeners provides a selection
from 3.3 to 200 volts with different tolerance options available. This series is equivalent to the
JEDEC registered 1N5913 thru 1N5956 series with identical electrical characteristics except
these are rated at 2.0 W instead of 1.5 W with the lower thermal resistance features of the
surface mount packaging. Its featured J-bend design in the DO-214AA package is ideal for
greater PC board mounting density. It is also available as RoHS compliant with an e3 suffix.
Microsemi also offers numerous other Zener products to meet higher and lower power
applications.

FEATURES
• Surface mount equivalent to JEDEC registered 1N5913 thru 1N5956.
• Ideal for high-density and low-profile mounting.
• Zener voltage available 3.3 V to 200 V.
• Standard voltage tolerances are plus/minus 5% and 10%.
• A tighter tolerance is available in plus or minus 2%.
• RoHS compliant versions available.

SMBG5913 – SMBG5956B
APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range.
• Wide selection from 3.3 to 200 V.
• Non-sensitive to ESD per MIL-STD-750 method 1020.
• Withstands high surge stresses (see Figure 2).
• Minimal changes of voltage versus current.
• High specified maximum current (IZM) when adequately heat sunk.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required.

SYMBOLS & DEFINITIONS
Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Reverse Voltage: The reverse voltage dc value, no alternating component.
Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a
specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively.
