Product details
Overview
SMBG5376B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 87 V, ±5% tolerance (B suffix), 15 mA test current (IZT), 75 Ω dynamic impedance (ZZT), and maximum regulator current of 54.5 mA (IZM) at 25 °C. It operates in voltage regulation and overvoltage protection circuits for industrial power supplies and DC-DC converters.
For engineers reviewing the SMBG5376B/TR13 datasheet, SMBG5376B/TR13 pinout, SMBG5376B/TR13 application, or SMBG5376B/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (IZSM = 760 A), thermal resistance (RθJA = 90 °C/W), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device functions as a precision shunt voltage regulator, maintaining stable output voltage across wide operating current (15 mA IZT to 54.5 mA IZM) and temperature ranges (–65 to +150 °C). Its low dynamic impedance (75 Ω) ensures minimal voltage variation under load transients.
The SMBG5376B/TR13 uses silicon PN-junction construction with cathode band marking, RoHS-compliant matte-tin plating, and moisture sensitivity level 1-eliminating dry-pack requirements. It withstands non-repetitive 8.3 ms half-sine surge currents up to 760 A per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±5% at 15 mA - defines regulated output voltage with tight tolerance for stable reference applications. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports continuous regulation in thermally managed designs with lead heatsinking. |
| Dynamic Impedance (ZZT) | 75 Ω at 15 mA - limits output voltage deviation during current changes, critical for precision regulation. |
| Max Regulator Current (IZM) | 54.5 mA - sets upper DC current limit before thermal runaway; requires adequate PCB copper area for heat dissipation. |
| Surge Current (IZSM) | 760 A (8.3 ms half-sine) - enables robust transient overvoltage clamping without failure in surge-prone systems. |
| Junction Temp Range | –65 to +150 °C - allows operation in extended industrial and automotive under-hood environments. |
| Thermal Resistance RθJA | 90 °C/W on FR4 (1 oz Cu) - determines required board layout for safe power handling at ambient temperatures. |
Pinout & Package
DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by molded band; device operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential node in Zener regulation. | Must be routed to ground or return path; polarity reversal causes open-circuit behavior in regulation mode. |
| Cathode | Current exit point in reverse breakdown; connected to higher-potential node being regulated. | Banded terminal; connects to input rail or voltage source; determines regulation reference point in shunt topology. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB Equivalent | Identical electrical specs and test methods to legacy 1N5376B - enables drop-in replacement in legacy designs. |
| Gull-wing Lead Form | DO-215AA footprint enables visual solder joint inspection and reliable reflow attachment on high-density boards. |
| Moisture Sensitivity Level 1 | No dry pack or baking required before assembly - reduces manufacturing overhead and avoids moisture-induced popcorning. |
| RoHS Compliant Matte-Tin Plating | Lead-free finish compliant with IPC/JEDEC J-STD-020B - supports environmental compliance without sacrificing solderability. |
| High Surge Withstand | 760 A non-repetitive surge rating - protects downstream circuitry from lightning-induced or inductive-switching transients. |
Applications
| Industrial Power Supply Regulation | DC-DC Converter Reference Clamping |
|---|---|
Use Scenario: Stabilizing auxiliary bias rails in 48 V telecom power modules where primary regulation is provided by switching controllers.

Use Value: Survives repeated 12 V system load-dump pulses (ISO 7637-2 Pulse 5a) due to rugged silicon construction and 5 W rating. |
Use Scenario: Providing stable 87 V reference for calibration circuits in portable multimeters and benchtop power analyzers. IC Role / Device Role / Timing Role: Precision shunt regulator establishing known voltage node for ADC reference scaling. Use Value: Low 75 Ω dynamic impedance minimizes reference drift under varying load, improving measurement repeatability to ±0.1%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5376B | Same Zener voltage (87 V), ±5%, but axial T-18 package; higher RθJA (~120 °C/W); no gull-wing footprint. | Requires through-hole mounting and larger board area; unsuitable for automated SMT lines. | Select when legacy through-hole design or manual prototyping is preferred over surface-mount density. |
| SMBJ5376B | Same electrical specs and DO-214AA (J-bend) package; identical 5 W rating and 760 A surge, but different lead geometry. | Compatible with same PCB thermal pad but requires revised stencil and placement offset due to J-bend vs. gull-wing form factor. | Choose when existing DO-214AA footprint exists and gull-wing inspection is not required. |
Compared with SMBG5376B/TR13, 1N5376B trades SMT manufacturability for mechanical robustness in vibration-prone environments, while SMBJ5376B retains SMT compatibility but sacrifices visual solder joint verification-making SMBG5376B/TR13 optimal for high-reliability, high-volume automated assembly requiring post-reflow optical inspection.

FAQ
What is the Zener voltage tolerance for SMBG5376B/TR13?
The SMBG5376B/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its measured VZ at 15 mA test current falls between 82.65 V and 91.35 V at 25 °C, per Microsemi's T4-LDS-0246-1 specification sheet.
Does SMBG5376B/TR13 require dry packing before reflow soldering?
No, SMBG5376B/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow soldering-reducing process complexity and cost.
What is the maximum surge current rating for SMBG5376B/TR13?
The SMBG5376B/TR13 is rated for a non-repetitive peak surge current (IZSM) of 760 A, defined as an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet.
Is SMBG5376B/TR13 RoHS compliant?
Yes, SMBG5376B/TR13 features RoHS-compliant annealed matte-tin plating on its gull-wing leads, meeting EU Directive 2011/65/EU and Microsemi's e3 marking designation per the Part Nomenclature section of T4-LDS-0246-1.
How does the DO-215AA package of SMBG5376B/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5376B/TR13 has gull-wing leads enabling visual solder joint inspection, whereas DO-214AA (used by SMBJ5376B) uses J-bend leads. Both share identical thermal and electrical specs, but DO-215AA supports AOI verification and offers slightly lower RθJA (90 vs. ~100 °C/W).
