SMBJ5913 – SMBJ5956e3
MECHANICAL and PACKAGING
• CASE: Void-free transfer molded thermosetting epoxy body meeting UL94V-0.
• TERMINALS: Tin-lead or RoHS compliant annealed matte-tin plating solderable per MIL-STD-750, method 2026.
• MARKING: Part number without SMBx prefix (e.g. 5914B, 5914Be3, MX5946C, 5956A, etc.).
• POLARITY: Cathode indicated by band. Diode to be operated with the banded end positive with respect to the opposite end for
Zener regulation.

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.
