Product details
Overview
SMBG5379BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 110 V, ±5% tolerance (B suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It delivers stable voltage regulation across wide current and temperature ranges, supporting surge protection and precision reference functions in power supply feedback loops.
For engineers reviewing the SMBG5379BE3/TR13 datasheet, SMBG5379BE3/TR13 pinout, SMBG5379BE3/TR13 application, or SMBG5379BE3/TR13 equivalent, key selection criteria include its 110 V Zener voltage, 12 A maximum regulator current (IZM), 125 mA test current (IZT), 125 Ω dynamic impedance (ZZT), and thermal resistance of 25 °C/W junction-to-lead - all critical for high-reliability overvoltage clamping and DC reference design.
Technical Context
This device operates as a reverse-biased silicon Zener diode with sharp breakdown knee at 110 V under 125 mA test current. Its DO-215AA gull-wing package enables visible solder joints and supports automated optical inspection, while Level 1 moisture sensitivity eliminates dry-pack requirements.
The SMBG5379BE3/TR13 exhibits 125 Ω dynamic impedance at IZT = 125 mA and maintains <0.5 µA reverse leakage (IR) at VR = 88 V. Thermal performance is defined by RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 with recommended footprint, enabling 5 W dissipation only when lead temperature remains below 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at 125 mA - defines precise clamping threshold for overvoltage protection circuits. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or heatsinking to sustain full rating. |
| Dynamic Impedance (ZZT) | 125 Ω at 125 mA - determines regulation stiffness; lower values improve voltage stability under load transients. |
| Maximum Regulator Current (IZM) | 12 A - sets absolute DC current limit before thermal runaway; derived from PD/VZM = 5 W / 115.5 V. |
| Reverse Leakage (IR) | <0.5 µA at 88 V - ensures minimal standby power loss in high-impedance bias networks. |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial motor drive environments. |
| Thermal Resistance (RθJL) | 25 °C/W - quantifies heat transfer efficiency from die to lead; critical for calculating junction temperature rise. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; polarity must be observed during placement (banded end = cathode = positive terminal in reverse-bias operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to circuit ground or low-side reference point; forms return path for regulated current. |
| Cathode | Reverse-bias input / Zener breakdown terminal | Connected to protected node or voltage source; clamps excess voltage above 110 V to ground via anode. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5379B equivalent | Identical electrical specs and test methods to legacy through-hole 1N5379B, enabling drop-in replacement in upgraded SMT designs. |
| RoHS-compliant matte-tin plating (e3) | Eliminates lead-based solder compatibility concerns and meets global environmental compliance mandates without performance trade-offs. |
| Gull-wing leads (DO-215AA) | Enables visual solder joint inspection and reduces tombstoning risk during reflow, improving manufacturing yield. |
| Level 1 moisture sensitivity | Allows floor-life unlimited storage without dry packing - simplifies inventory handling and reduces BOM logistics overhead. |
| High surge current rating (IZSM) | 1000 A non-repetitive peak (8.3 ms half-sine) - provides robust transient voltage suppression against lightning-induced surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5379B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs; non-RoHS tin-lead plating. | Requires axial-leaded PCB layout and wave soldering; unsuitable for high-density SMT assemblies. | Select when legacy through-hole assembly is mandated or thermal mass of DO-41 improves natural convection cooling. |
| SMBJ5379B | J-bend DO-214AA package; same electrical specs but higher RθJA (100 °C/W vs. 90 °C/W); no e3 RoHS option listed in standard docs. | Lower profile than SMBG but less visible solder joints; slightly reduced thermal margin on FR4 boards. | Select when board height constraints prohibit gull-wing leads or when existing DO-214AA footprint reuse is prioritized. |
Compared with SMBG5379BE3/TR13, the 1N5379B offers identical regulation performance in through-hole form but lacks SMT manufacturability and RoHS compliance, while the SMBJ5379B trades visible solder joints and RoHS assurance for marginally worse thermal resistance - making SMBG5379BE3/TR13 optimal for new high-reliability SMT designs requiring audit-ready compliance.

FAQ
What is the Zener voltage tolerance for SMBG5379BE3/TR13?
The 'B' suffix in SMBG5379BE3/TR13 specifies ±5% Zener voltage tolerance, meaning the actual breakdown voltage falls between 104.5 V and 115.5 V at 125 mA test current. This tolerance is verified per JEDEC JESD201 standards and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5379BE3/TR13 require dry packing before PCB assembly?
No, SMBG5379BE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry packing or baking. This eliminates moisture-related popcorning risks during reflow and simplifies factory logistics compared to higher-level MSL devices.
What is the maximum continuous power dissipation for SMBG5379BE3/TR13 on a standard FR4 board?
On a standard 1 oz copper FR4 board with Microsemi's recommended pad layout, SMBG5379BE3/TR13 dissipates 1.38 W continuously at 25 °C ambient (TA). Full 5 W rating is only achievable when lead temperature (TL) is maintained below 25 °C - typically requiring external heatsinking or forced air cooling.
How does the DO-215AA package of SMBG5379BE3/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5379BE3/TR13 features outward-bent leads enabling visual solder joint inspection and improved reflow yield, whereas DO-214AA uses J-bend leads. DO-215AA also achieves lower RθJA (90 °C/W vs. 100 °C/W for DO-214AA) due to better thermal coupling to PCB copper planes.
Is SMBG5379BE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5379BE3/TR13 features RoHS-compliant annealed matte-tin plating (e3) rated for peak reflow temperatures up to 260 °C for 10 seconds, fully compatible with standard SAC305 lead-free reflow profiles. The device passes MIL-STD-750 Method 2026 solderability testing after exposure to multiple reflow cycles.
