Product details
Overview
SMBG5353BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 16 V, ±5% tolerance (B suffix), and maximum Zener current IZM of 6.0 mA at TL < 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and operates across –65 to +150 °C junction temperature range. It serves as a precision voltage reference or overvoltage clamp in power supply feedback loops.
For engineers reviewing the SMBG5353BE3/TR13 datasheet, SMBG5353BE3/TR13 pinout, SMBG5353BE3/TR13 application, or SMBG5353BE3/TR13 equivalent, key selection criteria include its 16 V Zener voltage, 6.0 mA maximum regulator current, 295 Ω dynamic impedance at 75 mA test current, and RoHS-compliant matte-tin plating per E3 marking.
Technical Context
This device functions as a two-terminal voltage regulator diode operating in reverse-biased breakdown mode. Its electrical behavior is defined by Zener voltage VZ = 16 V at IZT = 75 mA, dynamic impedance ZZT = 295 Ω, and knee impedance ZZK = 75 Ω at 1.0 mA - confirming stable regulation across wide current ranges.
Thermal performance is characterized by RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 board, enabling 5.0 W dissipation only when lead temperature TL remains below 25 °C. Reverse leakage IR ≤ 1.0 µA is specified at VR = 11.5 V, supporting low-power standby regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5353BRLG | Through-hole DO-41 package; identical VZ, tolerance, and electrical specs | Requires axial-leaded PCB layout; not suitable for automated SMT lines | Select when legacy through-hole assembly or manual prototyping is used |
| SMBJ5353B | J-bend DO-214AA package; same VZ and tolerance but higher RθJA (100 °C/W) | Lower thermal efficiency on FR4; reduced power handling at ambient temperature | Select when existing DO-214AA footprint is fixed and thermal derating is acceptable |
Compared with SMBG5353BE3/TR13, 1N5353BRLG offers identical regulation but demands manual assembly, while SMBJ5353B fits different land patterns and sacrifices ~10% thermal margin - making SMBG5353BE3/TR13 optimal for high-density, thermally constrained SMT designs.

FAQ
What is the Zener voltage and tolerance of SMBG5353BE3/TR13?
The SMBG5353BE3/TR13 has a nominal Zener voltage of 16 V with ±5% tolerance (denoted by the "B" suffix). This means the actual breakdown voltage falls between 15.2 V and 16.8 V when measured at 75 mA test current and 25 °C. The "E3" marking confirms RoHS-compliant matte-tin plating, and "TR13" indicates tape-and-reel packaging per EIA-481-1-A standard.
How does SMBG5353BE3/TR13 differ from the through-hole 1N5353B?
SMBG5353BE3/TR13 is the surface-mount DO-215AA gull-wing equivalent of the through-hole 1N5353B (DO-41). Both share identical electrical characteristics including 16 V Zener voltage, ±5% tolerance, and 5 W power rating. The key difference is package geometry: SMBG5353BE3/TR13 enables automated SMT assembly and visual solder inspection, whereas 1N5353B requires axial-leaded placement and wave soldering.
What is the maximum surge current rating for SMBG5353BE3/TR13?
The SMBG5353BE3/TR13 has a non-repetitive peak surge current (IZSM) rating of 6.0 A for an 8.3 ms half-sine waveform. This value is derived from its 5 W power rating and thermal mass, allowing it to absorb transient overvoltage events such as load dump or ESD-induced spikes without permanent degradation - provided surge repetition is limited per datasheet guidelines.
Can SMBG5353BE3/TR13 be used in place of SMBJ5353B?
SMBG5353BE3/TR13 and SMBJ5353B share identical Zener voltage and tolerance but differ in package: DO-215AA (gull-wing) vs. DO-214AA (J-bend). While electrically interchangeable, their footprints are not compatible. SMBG5353BE3/TR13 offers lower thermal resistance (RθJA = 90 °C/W vs. 100 °C/W), making it preferable for thermally demanding layouts - but PCB redesign is required to substitute one for the other.
What is the moisture sensitivity level (MSL) of SMBG5353BE3/TR13?
SMBG5353BE3/TR13 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it may be stored indefinitely at ≤30 °C/60% RH without baking prior to reflow soldering. This eliminates pre-reflow drying steps, reduces manufacturing cycle time, and lowers risk of popcorning - a key advantage for high-volume SMT production of SMBG5353BE3/TR13.
