Product details
Overview
SMBG5376BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 87 V, ±5% tolerance (B suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, withstands high surge stresses, and is used in overvoltage protection and precision reference circuits for industrial power supplies.
For engineers reviewing the SMBG5376BE3/TR13 datasheet, SMBG5376BE3/TR13 pinout, SMBG5376BE3/TR13 application, or SMBG5376BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, maximum surge current capability (760 A), thermal resistance (90 °C/W on FR4), and RoHS compliance for modern PCB assembly.
Technical Context
This device operates as a voltage-regulating diode in reverse-biased breakdown mode, with specified test current IZT = 15 mA and dynamic impedance ZZT = 75 Ω at that point. Its cathode band polarity and gull-wing lead geometry support visible solder joint inspection and high-density mounting.
The SMBG5376BE3/TR13 exhibits minimal voltage variation versus current due to low dynamic impedance and maintains stable regulation from –65 °C to +150 °C junction temperature. It delivers 5.0 W dissipation at TL < 25 °C or 1.38 W at TA = 25 °C on standard FR4 board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±5% at IZT = 15 mA - defines precise clamping threshold for overvoltage protection |
| Power Dissipation (PD) | 5.0 W at lead temperature < 25 °C - requires thermal management for sustained operation |
| Max Surge Current (IZSM) | 760 A (8.3 ms half-sine) - enables robust transient suppression in power rails |
| Dynamic Impedance (ZZT) | 75 Ω at IZT = 15 mA - determines regulation stiffness under load variation |
| Junction Temp Range | –65 °C to +150 °C - supports operation in harsh industrial and automotive environments |
| Thermal Resistance RθJA | 90 °C/W on FR4 (1 oz Cu) - informs heatsinking requirements for continuous DC operation |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 63 V - ensures low standby power loss in high-impedance bias networks |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; leads are tin-plated (RoHS-compliant matte-tin per e3 suffix); moisture sensitivity level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node; carries forward current up to 1.0 A (VF = 1.2 V) |
| Cathode (banded end) | Reverse breakdown terminal | Connected to higher-potential node; establishes regulated Zener voltage when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|

| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow attachment on high-density PCBs |
| Level 1 moisture sensitivity | No dry pack or baking required before assembly - reduces manufacturing overhead and handling risk |
| High surge current rating | 760 A non-repetitive peak (8.3 ms) - provides robust protection against lightning-induced transients and inductive switching spikes |
| Stable voltage vs. current | Low dynamic impedance (75 Ω) and tight ±5% tolerance - ensures predictable clamping in precision reference applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5376B | Axial-leaded T-18 package; identical VZ, IZT, and ZZT; no RoHS compliance (Sn/Pb plating) | Requires through-hole assembly and manual soldering; unsuitable for automated SMT lines | Select when retrofitting legacy through-hole boards or where RoHS is not mandated |
| SMBJ5376B | DO-214AA J-bend package; same electrical specs but different thermal resistance (RθJA = 80 °C/W vs. 90 °C/W) and footprint | Compatible with high-speed pick-and-place but requires revised pad layout and reflow profile validation | Select when existing design uses DO-214AA footprint or requires slightly better thermal performance on FR4 |
Compared with SMBG5376BE3/TR13, the 1N5376B offers identical regulation but lacks SMT compatibility and RoHS compliance, while SMBJ5376B matches functionally but demands PCB layout changes and has marginally improved thermal resistance.

FAQ
What is the Zener voltage tolerance of SMBG5376BE3/TR13?
The SMBG5376BE3/TR13 has a ±5% Zener voltage tolerance, indicated by the "B" suffix in the part number. This means its nominal 87 V Zener voltage is guaranteed between 82.65 V and 91.35 V at IZT = 15 mA and TL = 25 °C. The tolerance is verified per JEDEC test methods and applies across the full operating temperature range.
Does SMBG5376BE3/TR13 require dry packing before reflow soldering?
No, SMBG5376BE3/TR13 does not require dry packing before reflow soldering. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ambient conditions (≤30 °C/60% RH) without baking. This eliminates pre-reflow baking steps and reduces manufacturing complexity for high-volume SMT lines.
What is the maximum continuous power dissipation for SMBG5376BE3/TR13 on a standard PCB?
On a standard FR4 PCB with 1 oz copper and recommended footprint, SMBG5376BE3/TR13 delivers 1.38 W continuous power dissipation at TA = 25 °C. At lead temperature < 25 °C, it supports full 5.0 W - so thermal design must ensure lead temperature remains below 25 °C for rated power operation.
How does the gull-wing package of SMBG5376BE3/TR13 benefit automated assembly?
The gull-wing package of SMBG5376BE3/TR13 enables optical inspection of solder joints post-reflow, improving process yield and field reliability. Its symmetrical lead geometry supports consistent placement accuracy in high-speed pick-and-place machines, and the matte-tin (e3) finish ensures robust wetting and intermetallic formation during lead-free reflow profiles.
Is SMBG5376BE3/TR13 compatible with the legacy 1N5376B diode?
Yes, SMBG5376BE3/TR13 is electrically and functionally equivalent to the axial-leaded 1N5376B, with identical Zener voltage, test current, dynamic impedance, and surge ratings. The "SMBG" prefix denotes surface-mount packaging, while "e3" confirms RoHS compliance - making it a direct functional replacement where SMT assembly is required.
