Product details
Overview
SMBG5379C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 110 V, ±2% tolerance (C suffix), 12 mA test current (IZT), and 125 Ω dynamic impedance at IZT - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5379C/TR13 datasheet, SMBG5379C/TR13 pinout, SMBG5379C/TR13 application, or SMBG5379C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1000 A), thermal resistance (25 °C/W junction-to-lead), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (12 mA to 1000 A surge) and temperature (-65 to +150 °C) ranges. Its low dynamic impedance (125 Ω at 12 mA) 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 is 25 °C/W, enabling reliable 5 W operation with appropriate lead heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±2% at 12 mA - defines precise regulation point for feedback or clamping. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper or lead heatsinking. |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 12 mA - determines voltage deviation under current changes. |
| Max Surge Current (IZSM) | 1000 A (8.3 ms half-sine) - supports transient overvoltage suppression without failure. |
| Junction Temperature Range | -65 to +150 °C - enables use in automotive, industrial, and outdoor environments. |
| Reverse Leakage (IR) | 0.5 µA at 88 V - ensures low standby power loss in high-impedance bias networks. |
| Thermal Resistance (RθJL) | 25 °C/W - quantifies thermal path efficiency from junction to lead for thermal design. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end is positive during reverse-bias operation. Leads are RoHS-compliant matte-tin plated and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference/ground node in Zener regulator configuration | Connected to system ground or lower-potential rail; carries full regulator current. |
| Cathode | Regulated output node | Banded terminal; held at stable 110 V relative to anode under reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5379B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs. |
| ±2% Zener voltage tolerance (C suffix) | Enables tighter regulation than ±5% (B) or ±10% (A) variants - critical for precision references. |
| Level 1 moisture sensitivity | No dry pack required before reflow - reduces handling cost and process complexity. |
| Gull-wing lead form | Enables visual solder joint inspection and robust mechanical attachment on FR4 boards. |
| Non-ESD-sensitive | Qualified per MIL-STD-750 Method 1020 - eliminates ESD handling controls in assembly. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5379B | Same Zener voltage (110 V), ±5% tolerance, identical DO-214AA package - higher voltage uncertainty. | Acceptable where ±5% regulation is sufficient; not suitable for precision feedback loops. | Select when cost priority outweighs voltage accuracy and DO-214AA footprint is preferred. |
| SMBJ5379C | Same Zener voltage and tolerance, but DO-214AA J-bend package - different thermal resistance (RθJA = 90 °C/W vs. 25 °C/W junction-to-lead). | Lower thermal performance limits continuous power in high-ambient environments. | Choose only if board layout mandates J-bend leads; verify thermal derating using RθJA. |
Compared with SMBG5379C/TR13, 1N5379B trades voltage accuracy for lower cost and axial-leaded compatibility, while SMBJ5379C sacrifices thermal efficiency for J-bend mount flexibility - neither offers the same combination of ±2% tolerance, DO-215AA gull-wing visibility, and 25 °C/W junction-to-lead thermal path.

FAQ
What is the Zener voltage tolerance of SMBG5379C/TR13?
The "C" suffix in SMBG5379C/TR13 specifies a ±2% Zener voltage tolerance at 12 mA test current. This means the actual VZ falls between 107.8 V and 112.2 V under standard test conditions (TL = 30 °C), making it suitable for applications requiring tighter regulation than ±5% (B) or ±10% (A) variants.
Does SMBG5379C/TR13 require dry packing before reflow soldering?
No, SMBG5379C/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ambient conditions without dry packing. This eliminates baking steps prior to reflow and simplifies manufacturing logistics for high-volume PCB assembly.
What is the maximum surge current rating for SMBG5379C/TR13?
SMBG5379C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1000 A, defined as a single 8.3 ms half-sine waveform. This rating enables robust transient suppression in industrial power systems where short-duration overvoltages occur, such as motor drive commutation or relay coil de-energization.
How does the DO-215AA package of SMBG5379C/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5379C/TR13 features gull-wing leads for visible solder joints and superior thermal conduction (RθJL = 25 °C/W), whereas DO-214AA (used by SMBJ5379C) uses J-bend leads with higher thermal resistance (RθJA = 90 °C/W). The gull-wing form also improves mechanical reliability on flex-rigid PCBs.
Is SMBG5379C/TR13 compatible with JEDEC 1N5379B?
Yes, SMBG5379C/TR13 is electrically and functionally equivalent to JEDEC-registered 1N5379B per Microsemi documentation, sharing identical Zener voltage, test current, dynamic impedance, and surge ratings. However, SMBG5379C/TR13 uses DO-215AA surface-mount packaging versus the axial-leaded 1N5379B, requiring PCB layout adaptation.
