Product details
Overview
SMBG5364BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±5% tolerance (B suffix), 10 Ω dynamic impedance at 40 mA test current, and DO-215AA gull-wing package. It regulates voltage in power supply feedback loops, overvoltage protection circuits, and reference voltage generation for industrial power converters.
For engineers reviewing the SMBG5364BE3/TR13 datasheet, SMBG5364BE3/TR13 pinout, SMBG5364BE3/TR13 application, or SMBG5364BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (150 A), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, maintaining stable 33 V regulation across 1–150 mA operating current range. Its 10 Ω dynamic impedance ensures minimal voltage variation under load transients, and its 25 °C/W junction-to-lead thermal resistance supports reliable 5 W dissipation with adequate PCB copper heatsinking.
The SMBG5364BE3/TR13 uses a void-free UL94V-0 epoxy body and gull-wing leads compatible with standard SMT reflow profiles up to 260 °C for 10 s. Cathode polarity is marked by a band, and it meets MIL-STD-750 ESD immunity requirements without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±5% at 40 mA - defines precise clamping/reference level in feedback or protection paths |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - enables robust overvoltage handling in compact SMT layouts |
| Dynamic Impedance (ZZT) | 10 Ω at IZT = 40 mA - ensures <0.4 V deviation over ±10 mA load change |
| Max Surge Current (IZSM) | 150 A (8.3 ms half-sine) - withstands lightning-induced or inductive-switching transients |
| Junction-to-Lead RθJL | 25 °C/W - allows direct thermal path to PCB copper, critical for sustained 5 W operation |
| Reverse Leakage (IR) | <0.5 µA at 25.1 V - guarantees low standby power loss in high-impedance bias networks |
| Package | DO-215AA gull-wing - provides visual solder joint inspection and IPC/JEDEC Level 1 moisture sensitivity |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; leads are tin-lead or RoHS-compliant matte-tin plated per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground in Zener regulation | Connected to lower-potential node (e.g., power rail return or error amplifier output) |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse bias | Banded end; connected to feedback point or protected circuit input for 33 V clamping |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5364B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | Lead-free solder compatibility with peak reflow at 260 °C - meets global environmental compliance |
| Level 1 moisture sensitivity | No dry pack required - eliminates baking step and reduces assembly cost and risk |
| Gull-wing lead form | Visible solder joints after reflow - enables automated optical inspection (AOI) and reliability validation |
| High surge current rating | 150 A non-repetitive peak - protects downstream ICs from 8.3 ms line surges without external TVS |
Applications
| Switch-Mode Power Supply Feedback | Industrial Overvoltage Clamp |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Same 33 V ±5%, 5 W rating, but axial DO-204AL (T-18) package with leaded through-hole mounting | Requires PCB through-hole holes and wave soldering; unsuitable for high-density SMT-only boards | Select when legacy repair, prototyping with breadboards, or mixed-technology assembly is required |
| SMBJ5364B | Identical electrical specs but DO-214AA (J-bend) package; 30 °C/W RθJA vs. 90 °C/W for SMBG version | Lower thermal resistance in same footprint area; preferred for thermally constrained layouts | Choose when junction-to-ambient cooling dominates over junction-to-lead path, e.g., no internal copper heatsink |
Compared with SMBG5364BE3/TR13, 1N5364B requires mechanical redesign for SMT transition, while SMBJ5364B offers better ambient thermal performance but lacks the gull-wing visual inspection advantage critical for high-reliability manufacturing.

FAQ
What is the Zener voltage tolerance of SMBG5364BE3/TR13?
The SMBG5364BE3/TR13 has a Zener voltage tolerance of ±5%, denoted by the "B" suffix in its part number. At 40 mA test current and 25 °C, its specified VZ range is 31.35 V to 34.65 V. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet, and applies directly to the SMBG5364BE3/TR13 variant.
Is SMBG5364BE3/TR13 RoHS compliant?
Yes, SMBG5364BE3/TR13 is RoHS compliant, as indicated by the "e3" suffix in its part number. It features annealed matte-tin plating per J-STD-020B Level 1 moisture sensitivity, with no dry pack required. The device meets EU RoHS Directive 2011/65/EU and is certified for lead-free reflow up to 260 °C for 10 seconds.
What is the maximum surge current rating for SMBG5364BE3/TR13?
The SMBG5364BE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 150 A, specified for an 8.3 ms half-sine waveform. This value is listed in the Electrical Characteristics table on page 3 of the datasheet and reflects its capability to absorb transient energy without parametric shift or catastrophic failure.
How does the DO-215AA package of SMBG5364BE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5364BE3/TR13 uses gull-wing leads for visible solder joint inspection and lower junction-to-lead thermal resistance (25 °C/W), whereas DO-214AA (used in SMBJ5364B) employs J-bend leads with higher RθJL. Both are surface-mount, but DO-215AA supports tighter thermal coupling to PCB copper and automated optical inspection.
Can SMBG5364BE3/TR13 replace 1N5364B in existing designs?
SMBG5364BE3/TR13 is electrically equivalent to 1N5364B per Microsemi documentation, but not mechanically interchangeable due to package differences: SMBG5364BE3/TR13 uses DO-215AA SMT gull-wing, while 1N5364B uses axial DO-204AL. PCB layout and assembly process must be updated to accommodate the surface-mount footprint and reflow profile.
