Product details
Overview
SMBG5379CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 110 V, ±2% tolerance (C suffix), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 1000 A (8.3 ms half-sine), and operates from –65 °C to +150 °C junction temperature. Used in overvoltage protection circuits for industrial power supplies.
For engineers reviewing the SMBG5379CE3/TR13 datasheet, SMBG5379CE3/TR13 pinout, SMBG5379CE3/TR13 application, or SMBG5379CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability, thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, and compatibility with automated SMT assembly on FR4 boards.
Technical Context
This device functions as a precision voltage reference and transient suppressor in DC bias networks and clamping stages. Its 110 V Zener voltage is specified at 12 mA test current (IZT), with dynamic impedance of 125 Ω at that point and knee impedance of 45 Ω at 1 mA (IZK).
Designed for stable regulation under varying load conditions, it exhibits low voltage drift versus current and maintains <0.5 µA reverse leakage at 88 V (VR). Thermal performance relies on low RθJL (25 °C/W) when soldered to copper leads, enabling reliable 5 W dissipation at lead temperature <25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±2% at 12 mA - defines precise clamping threshold for overvoltage events |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or heatsink attachment |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 12 mA - determines regulation stiffness under small-signal AC ripple |
| Surge Current (IZSM) | 1000 A (8.3 ms half-sine) - withstands lightning-induced transients per IEC 61000-4-5 |
| Reverse Leakage (IR) | <0.5 µA at VR = 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 - enables direct thermal path to PCB leads for efficient heat extraction |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking. Cathode terminal is banded end; device operates with cathode positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return path; carries full regulator current during conduction |
| Cathode | Regulated output node | Banded terminal; held at stable 110 V above anode during breakdown; connects to protected circuit input |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5379B equivalence | Identical electrical specs and test methods - simplifies legacy design migration and qualification reuse |
| RoHS-compliant matte-tin plating | e3 suffix indicates annealed tin finish meeting MIL-STD-750 method 2026 - ensures solderability without lead-based alloys |
| Gull-wing lead geometry | DO-215AA footprint with visible solder joints - enables AOI inspection and rework accessibility |
| Moisture sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B - eliminates baking step before SMT reflow |
| High surge current rating | 1000 A non-repetitive peak - provides robust protection against ESD and line surges without external TVS staging |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5379BRLG | Same 110 V ±2%, but in axial DO-204AL (T-18) package; higher RθJA (125 °C/W) | Requires through-hole mounting and manual assembly; unsuitable for high-density SMT layouts | Select when legacy board redesign is impractical and thermal constraints allow axial form factor |
| SMBJ110A | TVS diode (not Zener); 110 V standoff, 173 V clamping; unidirectional; 600 W peak pulse power | Designed for fast transient suppression (ns response), not precision DC regulation | Choose for ESD/EMP hardening where clamping speed matters more than voltage accuracy |
Compared with 1N5379BRLG and SMBJ110A, SMBG5379CE3/TR13 uniquely combines ±2% DC voltage accuracy, 5 W continuous power handling, and gull-wing SMT compatibility-making it optimal for space-constrained, thermally managed voltage reference and clamping designs requiring long-term stability.

FAQ
What is the Zener voltage tolerance of SMBG5379CE3/TR13?
The SMBG5379CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This means its nominal 110 V Zener voltage is guaranteed between 107.8 V and 112.2 V at 12 mA test current and 25 °C ambient, supporting precision clamping in regulated power rails and reference circuits.
Does SMBG5379CE3/TR13 require dry packing before reflow soldering?
No, SMBG5379CE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity Level 1 classification, meaning it can be stored indefinitely at standard humidity without baking prior to SMT reflow. This simplifies manufacturing logistics and reduces process risk for high-volume production.
What is the maximum surge current rating for SMBG5379CE3/TR13?
The SMBG5379CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1000 A with an 8.3 ms half-sine waveform. This rating reflects its ability to absorb high-energy transients-such as those from inductive switching or lightning coupling-without failure, making it suitable for primary-stage overvoltage protection.
How does the DO-215AA package of SMBG5379CE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5379CE3/TR13 features gull-wing leads for visible solder joints and lower profile than DO-214AA's J-bend configuration. While both are surface-mount, DO-215AA offers better thermal conduction (RθJL = 25 °C/W vs. ~30–35 °C/W for DO-214AA) and improved optical inspection access-critical for automotive and industrial quality assurance.
Is SMBG5379CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5379CE3/TR13 is fully compatible with lead-free reflow profiles. Its e3 suffix confirms RoHS-compliant matte-tin plating, qualified per MIL-STD-750 method 2026, and rated for solder temperatures up to 260 °C for 10 seconds-meeting JEDEC J-STD-020D requirements for Pb-free assembly processes.
