Product details
Overview
SMBG5364A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 33 V, ±10% tolerance (A suffix), 10 mA test current (IZT), and dynamic impedance of 10 Ω at IZT - used for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation.
For engineers reviewing the SMBG5364A/TR13 datasheet, SMBG5364A/TR13 pinout, SMBG5364A/TR13 application, or SMBG5364A/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 high-density PCB layouts.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable voltage across wide current (10 mA to 150 mA) and temperature (-65 °C to +150 °C) ranges. Its low dynamic impedance (10 Ω) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements. Thermal resistance junction-to-lead (25 °C/W) enables effective heat transfer to PCB copper when mounted per recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±10% - defines regulated output voltage at 10 mA; high-end tolerance limit is 36.3 V for worst-case design margining. |
| Test Current (IZT) | 10 mA - operating point where VZ and dynamic impedance are specified; sets minimum bias current for stable regulation. |
| Dynamic Impedance (ZZT) | 10 Ω - small-signal AC impedance at 10 mA; determines output voltage ripple rejection under varying load currents. |
| Max Regulator Current (IZM) | 150 mA - maximum continuous DC current at TL < 25 °C; corresponds to 5 W power dissipation at nominal VZ. |
| Surge Current (IZSM) | 150 A - non-repetitive 8.3 ms half-sine peak current; supports transient overvoltage clamping without failure. |
| Thermal Resistance (RθJL) | 25 °C/W - junction-to-lead thermal path efficiency; enables direct heat conduction to PCB copper via leads for thermal management. |
| Reverse Leakage (IR) | 0.5 µA @ 25.1 V - ultra-low leakage below knee voltage; critical for low-power standby circuits and battery-backed systems. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; leads are tin-lead or RoHS-compliant matte-tin plated per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; establishes polarity for reverse-bias operation. |
| Cathode | Regulated output node | Banded end; supplies stable 33 V reference when reverse-biased above breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5364B equivalent | Identical electrical characteristics and testing to through-hole 1N5364B - enables drop-in replacement in legacy designs. |
| Level 1 moisture sensitivity | No dry pack required before reflow - reduces handling cost and simplifies SMT assembly logistics. |
| Gull-wing lead form | Visible solder joints enable automated optical inspection (AOI) - improves manufacturing yield and field reliability verification. |
| High surge current capability | 150 A non-repetitive 8.3 ms half-sine rating - protects downstream ICs from lightning-induced or ESD-related transients. |
| Low dynamic impedance | 10 Ω at 10 mA - maintains voltage stability within ±0.1 V for ±1 mA load current variation in feedback networks. |
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 | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs; no gull-wing leads. | Requires axial-leaded PCB footprint; unsuitable for high-density SMT layouts. | Select when retrofitting legacy through-hole boards or when thermal mass of DO-41 aids heat dissipation in low-airflow enclosures. |
| SMBJ5364 | Same DO-214AA package; identical electrical specs but J-bend leads instead of gull-wing; RθJA = 90 °C/W vs. 90 °C/W (same). | Compatible with standard SMT pick-and-place but lacks visible solder joints for AOI. | Select when existing DO-214AA footprint is fixed and visual inspection is not required; verify pad layout matches J-bend geometry. |
Compared with SMBG5364A/TR13, 1N5364B offers identical regulation performance but requires board redesign for through-hole mounting, while SMBJ5364 retains surface-mount compatibility but sacrifices AOI capability due to concealed solder joints.

FAQ
What is the Zener voltage tolerance for SMBG5364A/TR13?
The 'A' suffix in SMBG5364A/TR13 indicates ±10% Zener voltage tolerance, meaning the actual breakdown voltage falls between 29.7 V and 36.3 V at 10 mA test current and 25 °C. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range of -65 °C to +150 °C.
Does SMBG5364A/TR13 require dry packing before reflow soldering?
No, SMBG5364A/TR13 has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - the lowest classification - so it does not require dry packing or baking prior to reflow. The DO-215AA package uses void-free epoxy meeting UL94V-0 and is rated for standard 260 °C, 10-second solder temperature exposure.
What is the maximum continuous Zener current for SMBG5364A/TR13?
The maximum continuous Zener current (IZM) for SMBG5364A/TR13 is 150 mA when lead temperature (TL) is maintained below 25 °C. At ambient temperature (TA) = 25 °C on FR4 with recommended footprint, derated power is 1.38 W, limiting IZM to approximately 42 mA - consult Figure 1 derating curve for precise thermal limits.
How does SMBG5364A/TR13 compare to SMBJ5364 in terms of package and assembly?
SMBG5364A/TR13 uses DO-215AA gull-wing leads enabling visible solder joints for AOI, while SMBJ5364 uses DO-214AA J-bend leads with hidden solder fillets. Both share identical electrical specs and thermal resistance junction-to-ambient (90 °C/W), but SMBG5364A/TR13's gull-wing form supports higher process yield in automated SMT lines requiring post-reflow inspection.
Is SMBG5364A/TR13 RoHS compliant?
SMBG5364A/TR13 is not RoHS compliant by default - the 'A' suffix denotes ±10% tolerance only; RoHS compliance requires the 'e3' suffix (e.g., SMBG5364Ae3/TR13). Standard SMBG5364A/TR13 uses Sn/Pb plating unless otherwise specified, and RoHS versions must be explicitly ordered with e3 marking.
