Product details
Overview
SMBG5364B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±5% tolerance (B suffix), 10 mA test current (IZT), and 150 mA maximum regulator current (IZM). It operates in reverse-biased breakdown mode for precision voltage regulation in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the SMBG5364B/TR13 datasheet, SMBG5364B/TR13 pinout, SMBG5364B/TR13 application, or SMBG5364B/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 150 A), and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, where regulated output voltage is maintained across its cathode–anode terminals under controlled current conditions. Its dynamic impedance (ZZT = 10 Ω at IZT) and low knee impedance (ZZK = 144 Ω at 1 mA) ensure stable regulation across varying load currents.
The SMBG5364B/TR13 is rated for 5 W dissipation at lead temperature ≤25 °C, derating linearly above that point per the published power derating curve. It meets MIL-STD-750 ESD immunity (Method 1020) and has IPC/JEDEC J-STD-020B moisture sensitivity level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±5% at 10 mA - defines precise clamping threshold for overvoltage protection and feedback sensing |
| Power Dissipation (PD) | 5.0 W at TL ≤25 °C - requires thermal management via PCB copper pour or heatsinking for sustained operation |
| Dynamic Impedance (ZZT) | 10 Ω at IZT = 10 mA - low AC impedance ensures minimal voltage variation under ripple or transient load changes |
| Max Regulator Current (IZM) | 150 mA - sets upper limit for continuous DC bias current without exceeding power rating |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - enables robust transient suppression in surge-prone industrial power rails |
| Thermal Resistance (RθJL) | 25 °C/W - quantifies junction-to-lead heat transfer efficiency; critical for thermal design on FR4 boards |
| Reverse Leakage (IR) | 0.5 µA at VR = 25.1 V - confirms tight blocking behavior below breakdown, minimizing standby power loss |
Pinout & Package
Package: DO-215AA gull-wing surface-mount package with void-free thermosetting epoxy body (UL94V-0), matte-tin RoHS-compliant plating, and visible solder joints for optical inspection. Cathode indicated by band; banded end must be biased positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal during reverse breakdown | Connected to regulated node or feedback input; polarity reversal causes forward conduction and failure |
| Anode (unbanded end) | Reference/ground terminal | Typically tied to system ground or return path; establishes reference potential for Zener voltage drop |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5364B equivalent | Identical electrical specs and test methods - enables legacy design reuse without qualification retesting |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow yield on fine-pitch SMT lines |
| Moisture Sensitivity Level 1 | No dry pack or baking required before assembly - reduces manufacturing overhead and handling risk |
| High surge current capability | 150 A non-repetitive peak withstand - protects downstream circuitry from lightning-induced transients |
| Low dynamic impedance | 10 Ω at 10 mA - maintains <±0.1 V regulation error across typical load current variations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Axial-leaded T-18 package; identical VZ, IZT, and IZM; RθJA = 120 °C/W vs. 90 °C/W for SMBG version | Requires through-hole assembly; unsuitable for high-density SMT layouts | Select when board space allows axial mounting and thermal constraints permit higher ambient rise |
| SMBJ5364B | J-bend DO-214AA package; same electrical specs but different lead geometry and RθJL = 30 °C/W | Compatible with standard SMT pick-and-place but lacks gull-wing visibility for AOI inspection | Choose for legacy DO-214AA footprint reuse or when gull-wing inspection is not required |
Compared with 1N5364B and SMBJ5364B, the SMBG5364B/TR13 offers superior thermal performance (RθJL = 25 °C/W), gull-wing leads for automated optical inspection, and identical regulation accuracy - making it optimal for high-reliability, high-density SMT power systems.

FAQ
What is the Zener voltage tolerance for SMBG5364B/TR13?
The SMBG5364B/TR13 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix in its part number per Microsemi's nomenclature. At 10 mA test current (IZT), this yields a guaranteed VZ range of 31.35 V to 34.65 V. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5364B/TR13 require dry packing before SMT assembly?
No, SMBG5364B/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored and assembled without baking or humidity-controlled packaging. This eliminates pre-reflow drying steps and reduces handling risk in high-volume SMT lines.
What is the maximum surge current rating for SMBG5364B/TR13?
The SMBG5364B/TR13 is rated for 150 A maximum non-repetitive surge current (IZSM) using an 8.3 ms half-sine waveform. This value is measured under standardized conditions and reflects its ability to absorb transient energy without failure - critical for protecting sensitive loads in industrial motor drives and automotive systems.
How does the thermal resistance of SMBG5364B/TR13 compare to axial alternatives?
SMBG5364B/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, significantly lower than the 120 °C/W of axial 1N5364B. This enables more efficient heat transfer to the PCB copper, supporting higher continuous power dissipation in compact SMT layouts without additional heatsinking.
Is SMBG5364B/TR13 RoHS compliant?
Yes, SMBG5364B/TR13 is RoHS compliant, as indicated by the "e3" marking option and confirmed in Microsemi's documentation. It uses annealed matte-tin plating instead of Sn/Pb, satisfying Directive 2011/65/EU requirements for lead-free electronics manufacturing.
