Product details
Overview
SMBG5361CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 27 V, ±2% tolerance (C suffix), 5.0 Ω dynamic impedance at 50 mA test current, and maximum Zener current of 120 mA. It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial and telecom equipment.
For engineers reviewing the SMBG5361CE3/TR13 datasheet, SMBG5361CE3/TR13 pinout, SMBG5361CE3/TR13 application, or SMBG5361CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (4.1 A peak), 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 output voltage over wide current (5–120 mA) and temperature (−65 to +150 °C) ranges. Its DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts.
The SMBG5361CE3/TR13 exhibits low dynamic impedance (5.0 Ω at IZT = 50 mA) and minimal voltage drift versus current-critical for feedback stability in switching regulators. It withstands non-repetitive 8.3 ms half-sine surges up to 4.1 A per JEDEC JESD22-A112A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±2% at 50 mA - ensures tight regulation in feedback networks requiring <±2% output accuracy. |
| Power Dissipation | 5.0 W at TL < 25 °C - supports continuous operation with adequate heat sinking on lead frame. |
| Dynamic Impedance (ZZT) | 5.0 Ω at 50 mA - minimizes output voltage variation under load transients in regulator circuits. |
| Max Zener Current (IZM) | 120 mA - defines safe DC operating limit before thermal runaway under full-rated power. |
| Surge Current (IZSM) | 4.1 A (8.3 ms half-sine) - provides robust transient overvoltage clamping without failure. |
| Junction-to-Lead RθJL | 25 °C/W - enables direct thermal path to PCB copper, critical for reliability in high-power density designs. |
| Reverse Leakage (IR) | 0.5 µA at 20.1 V - ensures negligible standby current in battery-powered protection circuits. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; forms return path for Zener current. |
| Cathode | Regulated output node | Provides stable 27 V reference when reverse-biased; connects to feedback divider or clamp point. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow soldering per JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. |
| ±2% Zener voltage tolerance | Reduces need for post-assembly trimming in precision voltage references and feedback circuits. |
| Gull-wing lead form (DO-215AA) | Permits visual solder joint inspection and accommodates automated optical inspection (AOI) in high-volume manufacturing. |
| Non-sensitive to ESD | Rated per MIL-STD-750 Method 1020-eliminates need for special ESD handling in assembly lines. |
| High surge current rating | Withstands 4.1 A transient surges-reduces need for external TVS devices in cost-sensitive overvoltage protection. |
Applications
| Switching Power Supply Feedback | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Used in TL431-based or discrete op-amp feedback networks to regulate 24 V DC-DC converter output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361BRLG | Same 27 V ±5% Zener voltage, axial T-18 package, higher RθJA (125 °C/W). | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs. | Select when legacy through-hole assembly or higher ambient temperature derating margin is needed. |
| SMBJ5361B | Identical electrical specs but J-bend DO-214AA package; same 5 W rating and 27 V ±5% tolerance. | Lower profile than SMBG but no visible solder joints; less suitable for AOI inspection. | Choose for space-constrained boards where gull-wing visibility is not required. |
Compared with SMBG5361CE3/TR13, 1N5361BRLG offers mechanical robustness in harsh vibration environments but sacrifices SMT efficiency, while SMBJ5361B matches performance in a lower-profile package at the cost of solder joint visibility and thermal resistance (RθJL = 30 °C/W vs. 25 °C/W).

FAQ
What is the Zener voltage tolerance of SMBG5361CE3/TR13?
The SMBG5361CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its measured VZ falls between 26.46 V and 27.54 V at 50 mA test current and 25 °C. This tighter tolerance supports precision feedback applications where output regulation better than ±1% is required without post-production trimming.
Does SMBG5361CE3/TR13 require dry packing before reflow soldering?
No, SMBG5361CE3/TR13 does not require dry packing prior to reflow soldering. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. The DO-215AA package uses void-free epoxy meeting UL94V-0, eliminating moisture ingress risk during standard lead-free reflow profiles up to 260 °C.
What is the maximum surge current rating for SMBG5361CE3/TR13?
The SMBG5361CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 4.1 A, defined per JEDEC JESD22-A112A as an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet and reflects its ability to absorb transient energy without parametric shift or catastrophic failure.
How does the thermal resistance of SMBG5361CE3/TR13 compare to axial Zeners like 1N5361B?
SMBG5361CE3/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, significantly lower than the ~125 °C/W of axial 1N5361B. This allows SMBG5361CE3/TR13 to dissipate 5 W more efficiently when mounted on PCB copper, reducing junction temperature rise by up to 100 °C under identical conditions-critical for long-term reliability in enclosed enclosures.
Can SMBG5361CE3/TR13 be used as a direct replacement for SMBG5361B in existing designs?
Yes, SMBG5361CE3/TR13 is a direct functional replacement for SMBG5361B, sharing identical package (DO-215AA), pinout, and Zener voltage (27 V), but with tighter ±2% tolerance instead of ±5%. No PCB layout changes are needed; however, the improved tolerance may reduce downstream calibration steps in feedback circuits where SMBG5361B previously required adjustment.
