Product details
Overview
SMBG5365C/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal breakdown voltage of 36 V, ±2% tolerance (C suffix), and maximum dynamic impedance of 11 Ω at 30 mA test current. It operates across –65 °C to +150 °C junction temperature and delivers stable voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation for industrial DC-DC converters.
For engineers reviewing the SMBG5365C/TR13 datasheet, SMBG5365C/TR13 pinout, SMBG5365C/TR13 application, or SMBG5365C/TR13 equivalent, this part serves as a RoHS-compliant, gull-wing DO-215AA packaged Zener with verified 36 V regulation, 30 mA test current, 11 Ω dynamic impedance, and 160 mA maximum regulator current - critical for precision clamping and low-drift biasing.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse-biased breakdown mode. Its Zener voltage is specified at 36 V ±2% under 30 mA dc test current (IZT), with dynamic impedance measured at 1 kHz ac modulation superimposed on IZT.
The SMBG5365C/TR13 exhibits thermal resistance of 25 °C/W junction-to-lead and 90 °C/W junction-to-ambient (on FR4, 1 oz Cu), enabling reliable 5 W dissipation only when lead temperature remains below 25 °C - requiring appropriate PCB copper area or heatsinking for sustained operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±2% at 30 mA - ensures tight regulation tolerance for feedback sensing in 48 V rail systems. |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - requires thermal management via PCB copper or lead conduction to avoid derating. |
| Dynamic Impedance (ZZT) | 11 Ω at 30 mA - low impedance maintains stable output voltage under varying load currents. |
| Max Regulator Current (IZM) | 160 mA - defines absolute upper limit for continuous Zener bias without exceeding 5 W rating. |
| Reverse Leakage (IR) | ≤0.5 µA at 28.1 V - negligible leakage preserves accuracy in high-impedance reference nodes. |
| Junction Temp Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial motor drive environments. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals are exposed on opposite sides of the molded epoxy body for visible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential node; must be routed with low-inductance path for stability. |
| Cathode | Regulated output node | Banded end; connects to feedback point or clamped rail; polarity reversal causes forward conduction and failure. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow assembly per JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack required. |
| Gull-wing lead form (DO-215AA) | Provides visual solder joint inspection and mechanical robustness for automated optical inspection (AOI) in high-volume SMT lines. |
| JEDEC 1N53xxB equivalent | Guarantees identical electrical specs and test methods to legacy through-hole 1N5365B - simplifies redesign migration. |
| High surge current rating | 160 A non-repetitive 8.3 ms half-sine surge (IZSM) - protects downstream circuitry against transient overvoltage events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Identical electrical specs, axial-leaded T-18 package instead of DO-215AA surface mount. | Requires through-hole assembly and board space; unsuitable for high-density SMT layouts. | Select when legacy through-hole manufacturing or manual prototyping is preferred. |
| SMBJ5365C | Same Zener voltage and tolerance, but J-bend DO-214AA package with higher RθJA (100 °C/W vs. 90 °C/W). | Lower thermal performance on same PCB footprint; may require larger copper area for equivalent power handling. | Select when existing DO-214AA footprint reuse is prioritized over optimal thermal conduction. |
Compared with SMBG5365C/TR13, 1N5365B offers identical regulation but lacks surface-mount compatibility, while SMBJ5365C trades thermal efficiency for footprint compatibility - making SMBG5365C/TR13 optimal for new SMT designs demanding both precision and manufacturability.

FAQ
What is the Zener voltage tolerance for SMBG5365C/TR13?
The "C" suffix in SMBG5365C/TR13 specifies a ±2% Zener voltage tolerance at 30 mA test current. This yields a guaranteed VZ range of 35.28 V to 36.72 V under standard test conditions (TL = 25 °C), making SMBG5365C/TR13 suitable for applications requiring tighter regulation than ±5% (B suffix) or ±10% (A suffix) variants.
Can SMBG5365C/TR13 replace 1N5365B in a design?
Yes - SMBG5365C/TR13 is the surface-mount DO-215AA equivalent of the axial-leaded 1N5365B, with identical electrical characteristics per Microsemi documentation. However, replacing 1N5365B with SMBG5365C/TR13 requires PCB layout revision to accommodate the gull-wing footprint and soldering profile adjustments for RoHS-compliant reflow.
What is the maximum continuous current SMBG5365C/TR13 can handle?
The maximum continuous Zener current (IZM) for SMBG5365C/TR13 is 160 mA, calculated from PD = 5.0 W and VZ = 36 V at the upper tolerance limit (36.72 V). Operation above this current risks thermal runaway unless lead temperature is actively maintained below 25 °C via heatsinking or PCB copper area.
Does SMBG5365C/TR13 require dry packing before reflow?
No - SMBG5365C/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is not hygroscopic and does not require dry pack or baking prior to reflow soldering. The void-free epoxy encapsulation and matte-tin plating ensure robustness through standard lead-free reflow profiles up to 260 °C for 10 seconds.
How is polarity marked on SMBG5365C/TR13?
SMBG5365C/TR13 uses a cathode band marking on the black epoxy body - the banded end is the cathode and must be connected to the higher-potential node (e.g., regulated rail or clamped voltage point). Reverse polarity connection will forward-bias the diode, causing excessive current flow and permanent damage to SMBG5365C/TR13.
