Product details
Overview
SMBG5376CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 87 V, ±2% tolerance (C suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges and is used in overvoltage protection and precision reference circuits in industrial power supplies.
For engineers reviewing the SMBG5376CE3/TR13 datasheet, SMBG5376CE3/TR13 pinout, SMBG5376CE3/TR13 application, or SMBG5376CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating (IZSM = 760 A), thermal resistance (RθJA = 90 °C/W), and compliance with JEDEC 1N5376B specifications.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable voltage under varying load and temperature conditions. Its dynamic impedance (ZZT = 75 Ω at IZT = 15 mA) and low knee impedance (ZZK = 54.5 Ω at 1 mA) ensure tight regulation near the breakdown knee.
Designed for high-surge environments, it withstands non-repetitive 8.3 ms half-sine surges up to 760 A and exhibits minimal voltage drift over -65 °C to +150 °C junction temperature range. Polarity is marked by cathode band; operation requires banded end positive relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±2% at 15 mA - precise reference for 85–90 V systems |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on FR4 board |
| Max Surge Current (IZSM) | 760 A (8.3 ms half-sine) - robust transient suppression capability |
| Dynamic Impedance (ZZT) | 75 Ω at IZT = 15 mA - low AC impedance ensures stable regulation |
| Junction Temp Range | -65 °C to +150 °C - suitable for harsh industrial environments |
| Thermal Resistance RθJA | 90 °C/W on FR4 (1 oz Cu) - dictates heatsinking requirements |
| Reverse Leakage (IR) | 0.5 µA at VR = 63 V - negligible standby loss in high-impedance bias networks |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; terminals are anode (unbanded end) and cathode (banded end). Moisture sensitivity level is IPC/JEDEC Level 1 - no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground in Zener regulation | Connected to lower-potential node (e.g., ground or return path) during regulation |
| Cathode | Current exit terminal in forward bias; regulated output node in Zener mode | Banded end connects to higher-potential rail (e.g., 87 V supply rail) for clamping |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5376B equivalence | Identical electrical specs and test methods - enables legacy design drop-in replacement |
| ±2% Zener tolerance (C suffix) | Tighter voltage control than ±5% (B) or ±10% (A) variants - reduces calibration overhead |
| RoHS-compliant matte-tin plating (e3) | Lead-free solder compatibility per J-STD-020B - supports modern assembly processes |
| Gull-wing lead form (DO-215AA) | Visible solder joints and automated optical inspection (AOI) compatibility - improves manufacturing yield |
| Level 1 moisture sensitivity | No dry pack or baking required before reflow - simplifies handling and inventory control |
Applications
| Industrial Power Supply Protection | Automotive ECU Voltage Clamp |
|---|---|
Use Scenario: Clamps transient overvoltage spikes on 24 V DC bus in PLC power modules during load dump or inductive switching. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to clamp voltage at 87 V, protecting downstream DC-DC converters and microcontrollers. Use Value: Withstands 760 A surge current and maintains regulation within ±2% - eliminates need for additional TVS stages in cost-sensitive designs. | Use Scenario: Provides overvoltage protection on 12 V battery-supplied sensor interface lines exposed to ISO 7637-2 pulse 5a transients. IC Role / Device Role / Timing Role: Standby Zener regulator that activates only during >87 V events, minimizing quiescent power draw. Use Value: Low 0.5 µA leakage at 63 V ensures negligible current drain on always-on vehicle circuits. |

Use Scenario: Serves as precision voltage reference in handheld multimeter front-end attenuator/divider networks requiring stable 87 V reference. IC Role / Device Role / Timing Role: Passive Zener reference providing fixed potential for ADC input scaling and calibration. Use Value: ±2% tolerance and low ZZK (54.5 Ω) minimize measurement error across temperature - meets Class II accuracy requirements. | Use Scenario: Monitors DC-link voltage in solar microinverters; triggers shutdown if DC bus exceeds safe threshold during grid fault. IC Role / Device Role / Timing Role: Overvoltage detection element feeding comparator input via resistive divider. Use Value: Stable VZ over -40 °C to +125 °C ensures reliable trip point across outdoor operating conditions without recalibration. |
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 VZ (87 V), ±5% tolerance, Sn/Pb plating, axial T-18 package | Requires through-hole PCB layout and wave soldering; not RoHS-compliant | Select when legacy through-hole assembly or Pb-based process is mandated |
| SMBJ5376B | Same VZ (87 V), ±5% tolerance, DO-214AA J-bend package, identical electrical specs | Different footprint and thermal profile (RθJA ~100 °C/W); slightly lower surge rating (720 A) | Select when DO-214AA footprint is standardized and ±5% tolerance suffices |
Compared with SMBG5376CE3/TR13, 1N5376B offers identical regulation but lacks RoHS compliance and surface-mount compatibility, while SMBJ5376B matches the SMT form factor but trades tighter tolerance and surge margin for footprint commonality.

FAQ
What is the Zener voltage tolerance of SMBG5376CE3/TR13?
The SMBG5376CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its measured VZ at 15 mA test current falls between 85.26 V and 88.74 V at 25 °C. The tighter tolerance supports precision regulation tasks where ±5% (B suffix) would introduce unacceptable error margins in feedback or reference circuits.
Does SMBG5376CE3/TR13 require dry packing before reflow soldering?
No, SMBG5376CE3/TR13 does not require dry packing. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored indefinitely at ambient conditions without baking or desiccant packaging. This simplifies inventory handling and eliminates pre-reflow bake cycles in manufacturing.
What is the maximum surge current rating for SMBG5376CE3/TR13?
The SMBG5376CE3/TR13 is rated for a maximum non-repetitive peak surge current (IZSM) of 760 A, defined as an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without failure, making it suitable for load-dump and inductive-switching protection in 24 V and 48 V industrial systems.
How does the DO-215AA package of SMBG5376CE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5376CE3/TR13 uses gull-wing leads for visible solder joints and AOI compatibility, whereas DO-214AA (used in SMBJ53xxB) employs J-bend leads. DO-215AA has lower RθJA (90 °C/W vs. ~100 °C/W for DO-214AA on FR4), enabling better thermal performance in compact layouts without heatsinks.
Is SMBG5376CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5376CE3/TR13 features RoHS-compliant annealed matte-tin plating (e3 suffix) and is qualified for lead-free reflow up to 260 °C for 10 seconds. Its thermosetting epoxy body meets UL94V-0 flammability rating, ensuring reliability under standard SAC305 soldering profiles without delamination or voiding.
