Product details
Overview
SMBG5363AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 30 V, ±10% tolerance (A suffix), and maximum Zener current IZM of 158 mA at 25 °C lead temperature. It uses DO-215AA gull-wing package, supports visible solder joints, and is RoHS-compliant (e3). It regulates voltage in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the SMBG5363AE3/TR13 datasheet, SMBG5363AE3/TR13 pinout, SMBG5363AE3/TR13 application, or SMBG5363AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 3.7 A), and moisture sensitivity level (MSL Level 1).
Technical Context
This device operates as a voltage reference and clamp in DC power rails, leveraging sharp reverse-breakdown characteristics at 30 V with dynamic impedance ZZT of 8.0 Ω at IZT = 40 mA. Its low RθJL enables stable regulation under pulsed loads when mounted on copper leads.
The SMBG5363AE3/TR13 exhibits minimal voltage drift over temperature (−65 °C to +150 °C) and maintains <0.5 µA reverse leakage at VR = 21.6 V. Its DO-215AA gull-wing terminals support automated optical inspection and high-reliability reflow soldering per JEDEC J-STD-020B.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Test Current (IZT) | 40 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZT) | 8.0 Ω - low AC impedance ensures stable regulation under varying load currents |
| Max Regulator Current (IZM) | 158 mA - maximum continuous DC current at TL ≤ 25 °C with adequate heat sinking |
| Surge Current (IZSM) | 3.7 A - non-repetitive 8.3 ms half-sine peak current for transient suppression |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient junction-to-lead heat transfer in PCB-mounted applications |
| Moisture Sensitivity | Level 1 - no dry pack required; safe for standard SMT assembly without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5363B | Same VZ, IZT, and ZZT; axial T-18 package with longer lead inductance and higher RθJA | Requires through-hole mounting; unsuitable for high-density SMT boards | Select when legacy board repair or prototyping with breadboard-friendly leads is needed |
| SMBJ5363B | Same electrical specs; DO-214AA J-bend package with higher RθJA (125 °C/W vs. 90 °C/W) and no gull-wing visibility | Limited optical inspection capability; less robust mechanical retention under thermal cycling | Select when footprint compatibility with existing SMBJ-series designs is prioritized over solder joint verification |
Compared with SMBG5363AE3/TR13, 1N5363B offers identical regulation but lacks SMT scalability, while SMBJ5363B trades gull-wing inspectability for footprint reuse-neither is pin-compatible, but both serve overlapping voltage-clamp functions in different mechanical contexts.

FAQ
What is the Zener voltage tolerance for SMBG5363AE3/TR13?
The SMBG5363AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in its part number. This means its actual breakdown voltage falls between 27.0 V and 33.0 V when measured at 40 mA test current and 25 °C lead temperature. The tolerance directly impacts regulation accuracy in feedback and clamp circuits, and must be accounted for in worst-case design margins.
Does SMBG5363AE3/TR13 require dry packing before SMT assembly?
No, SMBG5363AE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level (MSL) 1 certification, meaning it can be stored and assembled under standard ambient conditions without baking. This eliminates pre-reflow desiccation steps, reducing process complexity and cost in high-volume manufacturing.
What is the maximum surge current rating for SMBG5363AE3/TR13?
The SMBG5363AE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 3.7 A for an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without failure and is validated per Microsemi's test methodology. Designers should verify that external series impedance limits peak current to ≤3.7 A during expected surge events.
How does the DO-215AA package of SMBG5363AE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5363AE3/TR13 features gull-wing leads that extend outward and downward, enabling visual solder joint inspection and improved mechanical stability. In contrast, DO-214AA (used in SMBJ5363B) employs J-bend leads with tighter radius and less vertical standoff, limiting optical access and increasing risk of solder bridging in fine-pitch layouts.
Is SMBG5363AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5363AE3/TR13 is fully compatible with lead-free reflow profiles. Its matte-tin (e3) plating meets RoHS requirements and is rated for peak solder temperatures up to 260 °C for 10 seconds. The device's thermal resistance (RθJL = 25 °C/W) and epoxy body (UL94V-0) ensure reliable performance under standard JEDEC J-STD-020D reflow cycles.
