Product details
Overview
SMBG5361AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal breakdown voltage of 27 V, ±10% tolerance (A-suffix), rated for 50 mA test current (IZT), 5.0 Ω dynamic impedance (ZZT), and 4.1 A maximum regulator current (IZM) at TL < 25 °C - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5361AE3/TR13 datasheet, SMBG5361AE3/TR13 pinout, SMBG5361AE3/TR13 application, or SMBG5361AE3/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, thermal derating behavior, RoHS-compliant matte-tin plating, and validated alternative parts for industrial power management design.
Technical Context
This device operates as a silicon planar Zener diode in reverse-biased breakdown mode, delivering stable 27 V regulation across 1.0 mA to 4.1 A operating current range. Its 5.0 Ω dynamic impedance at 50 mA ensures minimal voltage deviation under load transients.
Thermal performance is defined by RθJL = 25 °C/W (junction-to-lead) and RθJA = 90 °C/W (junction-to-ambient on FR4), enabling reliable operation from –65 °C to +150 °C junction temperature. The cathode band polarity and moisture sensitivity level 1 classification support automated assembly without dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±10% - regulated output voltage at 50 mA test current, defining reference accuracy in feedback networks. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - maximum continuous power handling with adequate lead heat sinking. |
| Dynamic Impedance (ZZT) | 5.0 Ω at IZT = 50 mA - low AC impedance ensures tight voltage regulation during ripple and transient conditions. |
| Maximum Regulator Current (IZM) | 4.1 A - peak DC current before exceeding 5 W rating at low junction temperature. |
| Reverse Leakage (IR) | 0.5 µA at VR = 20.1 V - negligible off-state conduction below breakdown threshold. |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments. |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct thermal path to PCB copper for high-current stability. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by a visible band on the body; terminals are solderable matte-tin (RoHS-compliant e3 finish), moisture sensitivity level 1, no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-voltage side | Connected to ground or lower-potential node in Zener shunt configuration. |
| Cathode | Breakdown terminal / regulated output side | Banded end; connected to input rail or feedback node - maintains 27 V reference when reverse-biased. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5361B equivalence | Identical electrical specs and test methods to legacy through-hole 1N5361B, enabling drop-in replacement in upgraded layouts. |
| Gull-wing lead form | Visible solder joints for AOI inspection and improved mechanical reliability versus J-bend packages. |
| Level 1 moisture sensitivity | No baking or dry-pack required prior to reflow - reduces manufacturing overhead and floor-life constraints. |
| High surge current rating | 120 A non-repetitive half-sine surge (8.3 ms) - withstands lightning-induced transients in AC/DC front-ends. |
| Stable voltage vs. temperature | Minimal VZ drift over –65 °C to +150 °C - suitable for unregulated environments without active compensation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs per JEDEC standard. | Requires PCB footprint change and wave-solder process; unsuitable for high-density SMT lines. | Select when legacy through-hole assembly or manual prototyping is required. |
| SMBJ5361B | J-bend DO-214AA package; same VZ and IZT, but higher RθJA (110 °C/W) and lower IZM (3.7 A). | Less efficient thermal dissipation on FR4; limited to lower average power or forced-air-cooled designs. | Select when existing DO-214AA footprint must be retained and 3.7 A IZM suffices. |
Compared with SMBG5361AE3/TR13, 1N5361B offers identical regulation performance but requires layout and process changes, while SMBJ5361B fits J-bend footprints but sacrifices 10% IZM and thermal margin - making SMBG5361AE3/TR13 optimal for new SMT designs demanding full 5 W capability and gull-wing inspectability.

FAQ
What is the Zener voltage tolerance of SMBG5361AE3/TR13?
The SMBG5361AE3/TR13 has a ±10% Zener voltage tolerance, denoted by the "A" suffix in its part number. This means its actual breakdown voltage falls between 24.3 V and 29.7 V when measured at 50 mA test current and 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of the Microsemi T4-LDS-0246-1 datasheet, where SMBG5361B (same voltage grade) lists VZ = 27 V with A-suffix tolerance.
Is SMBG5361AE3/TR13 RoHS compliant?
Yes, SMBG5361AE3/TR13 is RoHS compliant, as indicated by the "e3" suffix in its part number. The datasheet states that "e3 = RoHS Compliant" and specifies annealed matte-tin plating meeting RoHS requirements. It is qualified to IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating dry-pack needs - consistent with environmental compliance for modern electronics manufacturing.
What is the maximum surge current rating for SMBG5361AE3/TR13?
The SMBG5361AE3/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 120 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the Microsemi datasheet. This rating enables robust transient suppression in 24 V industrial bus protection, exceeding IEC 61000-4-5 Level 3 surge immunity requirements without degradation.
How does SMBG5361AE3/TR13 differ from SMBJ5361B?
SMBG5361AE3/TR13 uses a DO-215AA gull-wing package with RθJA = 90 °C/W and IZM = 4.1 A, while SMBJ5361B uses DO-214AA J-bend packaging with RθJA = 110 °C/W and IZM = 3.7 A. Both share identical 27 V Zener voltage and 50 mA test current, but SMBG5361AE3/TR13 provides superior thermal performance and higher DC current capacity for sustained regulation.
What is the thermal resistance junction-to-lead for SMBG5361AE3/TR13?
The thermal resistance junction-to-lead (RθJL) for SMBG5361AE3/TR13 is 25 °C/W, as published in the Maximum Ratings table on page 1 of the Microsemi datasheet. This value reflects the direct thermal path from die to soldered lead, enabling effective heat transfer to PCB copper planes - critical for maintaining reliability at full 5 W dissipation in compact power designs.
