Product details
Overview
SMBG5376A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 87 V, ±10% tolerance (A-suffix), 15 mA test current (IZT), and 75 Ω dynamic impedance (ZZT) at IZT. It operates in reverse-biased regulation mode, provides stable voltage reference in power supply feedback loops, and withstands high-energy transients in industrial DC bus protection circuits.
For engineers reviewing the SMBG5376A/TR13 datasheet, SMBG5376A/TR13 pinout, SMBG5376A/TR13 application, or SMBG5376A/TR13 equivalent, key selection criteria include Zener voltage tolerance, surge current rating (IZSM = 760 A), thermal resistance (RθJA = 90 °C/W), junction temperature range (–65 to +150 °C), and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device functions as a precision voltage clamp in reverse-bias operation, maintaining regulation across 15 mA to 1.7 A (IZM) with minimal voltage drift over temperature. Its 87 V breakdown voltage is specified at TL = 30 °C with 40 ms settling time after DC current application.
The SMBG5376A/TR13 uses a void-free thermosetting epoxy case (UL94V-0), matte-tin RoHS-compliant plating, and cathode polarity marked by a band. It achieves Level 1 moisture sensitivity (IPC/JEDEC J-STD-020B) without dry-pack requirement and supports 260 °C soldering for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±10% - Stable regulation point at 15 mA, used for overvoltage clamping in 72–92 V DC systems. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - Requires thermal management on FR4 board; derates linearly above 25 °C per Figure 1. |
| Dynamic Impedance (ZZT) | 75 Ω at IZT = 15 mA - Low AC impedance ensures tight voltage regulation under varying load currents. |
| Max Surge Current (IZSM) | 760 A (8.3 ms half-sine) - Withstands lightning-induced surges in telecom and industrial power rails. |
| Reverse Leakage (IR) | 0.5 µA at VR = 63 V - Negligible standby power loss in high-impedance bias networks. |
| Junction Temp Range | –65 to +150 °C - Suitable for under-hood automotive, outdoor power converters, and industrial control enclosures. |
| Thermal Resistance | RθJA = 90 °C/W (FR4, 1 oz Cu) - Limits max ambient temp to ~80 °C at full 5 W dissipation with standard layout. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by a band on the body. Leads are tin-plated (RoHS compliant) and solderable per MIL-STD-750 Method 2026. Pad layout per Microsemi recommended footprint (A = 8.13 mm, B = 2.16 mm, C = 2.79 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to lower-potential side of protected circuit; forms return path during clamping. |
| Cathode | Zener breakdown terminal | Banded end; connected to higher-potential rail; conducts when voltage exceeds 87 V ±10%. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5376A equivalent | Identical electrical specs and test methods to legacy axial 1N5376A, enabling drop-in replacement in legacy designs. |
| Gull-wing lead form | Visible solder joints enable AOI inspection and reduce tombstoning risk in high-density PCB layouts. |
| Level 1 moisture sensitivity | No dry-pack or baking required before reflow, reducing manufacturing overhead and handling complexity. |
| High surge robustness | 760 A non-repetitive surge rating supports IEC 61000-4-5 Level 4 compliance in industrial power interfaces. |
Applications
| DC Bus Overvoltage Clamp | Industrial Power Supply Feedback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5376A | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM specs; no gull-wing leads. | Requires through-hole assembly; unsuitable for high-density SMT boards; larger board area footprint. | Select when legacy through-hole production or manual repair is required; not compatible with SMT reflow. |
| SMBJ5376A | DO-214AA (J-bend) package; same electrical specs but RθJA = 100 °C/W vs. 90 °C/W; 0.1 g vs. 0.1 g weight. | Lower thermal performance limits continuous power in confined spaces; different pad layout and pick-and-place tooling. | Select when DO-214AA footprint is already standardized; verify thermal margin in enclosed enclosures above 60 °C ambient. |
Compared with SMBG5376A/TR13, 1N5376A requires PCB redesign for SMT migration, while SMBJ5376A trades 10 °C/W higher thermal resistance for J-bend compatibility-both lack the gull-wing visibility and Level 1 moisture advantage of SMBG5376A/TR13.

FAQ
What is the Zener voltage tolerance for SMBG5376A/TR13?
The SMBG5376A/TR13 has a Zener voltage tolerance of ±10%, as indicated by the "A" suffix in the part number. This means its breakdown voltage is guaranteed between 78.3 V and 95.7 V at 15 mA test current and 30 °C lead temperature. The tolerance directly affects regulation accuracy in feedback and clamping circuits where precise voltage thresholds are required.
Does SMBG5376A/TR13 require dry packing before reflow soldering?
No, SMBG5376A/TR13 does not require dry packing before reflow soldering. It carries IPC/JEDEC J-STD-020B Level 1 moisture sensitivity classification, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow baking steps and reduces manufacturing cycle time and cost in high-volume SMT lines.
What is the maximum surge current rating for SMBG5376A/TR13?
The SMBG5376A/TR13 has a maximum non-repetitive peak surge current (IZSM) of 760 A, defined for an 8.3 ms half-sine waveform. This rating enables reliable protection against lightning-induced transients and inductive switching spikes in industrial and telecom power interfaces where standards like IEC 61000-4-5 apply.
How does the DO-215AA package of SMBG5376A/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5376A/TR13 features gull-wing leads that allow visual solder joint inspection and reduce tombstoning risk, whereas DO-214AA uses J-bend leads. Thermally, DO-215AA offers RθJA = 90 °C/W vs. DO-214AA's 100 °C/W on FR4, giving SMBG5376A/TR13 a 10 °C/W advantage in power dissipation capability under identical board conditions.
Is SMBG5376A/TR13 RoHS compliant?
Yes, SMBG5376A/TR13 is RoHS compliant, using annealed matte-tin plating per the "e3" designation implied by the TR13 tape-and-reel suffix and confirmed in Microsemi's documentation. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, meeting EU Directive 2011/65/EU requirements for restricted substances.
