Product details
Overview
SMBG5376AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 87 V, ±10% tolerance (A suffix), rated test current of 15 mA, maximum dynamic impedance of 75 Ω at IZT, and peak surge current capability of 760 A (8.3 ms half-sine). It operates in voltage regulation and overvoltage protection circuits for industrial power supplies and DC-DC converters.
For engineers reviewing the SMBG5376AE3/TR13 datasheet, SMBG5376AE3/TR13 pinout, SMBG5376AE3/TR13 application, or SMBG5376AE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), surge robustness (IZSM = 760 A), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device functions as a precision shunt voltage regulator in reverse-biased mode, maintaining stable output voltage across wide operating current (IZK to IZM) and temperature ranges (–65 °C to +150 °C). Its low dynamic impedance (75 Ω at 15 mA) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal performance is defined by RθJL = 25 °C/W (junction-to-lead) and RθJA = 90 °C/W (junction-to-ambient on FR4 with recommended footprint).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 87 V ±10% - Regulates at nominal 87 V with 7.83 V tolerance band; specified at 15 mA test current. |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - Full-rated power only when lead temperature is controlled; derates linearly above 25 °C. |
| Dynamic Impedance (ZZT) | 75 Ω max @ 15 mA - Low AC impedance ensures tight voltage regulation during small-signal ripple suppression. |
| Max Surge Current (IZSM) | 760 A (8.3 ms half-sine) - Withstands high-energy transient surges common in industrial power rails and motor drives. |
| Reverse Leakage (IR) | 0.5 µA max @ 63 V - Extremely low leakage at 72% of VZ, critical for low-power standby regulation. |
| Junction Temp Range | –65 °C to +150 °C - Enables operation in harsh environments including automotive under-hood and industrial control cabinets. |
| Thermal Resistance (RθJL) | 25 °C/W - Enables efficient heat transfer to PCB copper pour or heatsink via leads; supports high-reliability thermal design. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode for proper Zener operation. Leads are RoHS-compliant annealed matte-tin plated per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output reference node | Connected to higher-potential rail; voltage drop across diode establishes stable VZ referenced to anode. |
| Anode | Ground or return reference | Typically tied to system ground or low-side return path; completes current loop during regulation or clamping. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N53xxB equivalent | Identical electrical specs and testing to legacy through-hole 1N5376B - enables drop-in replacement in upgraded SMT designs. |
| Level 1 moisture sensitivity | No dry pack or baking required before reflow - reduces manufacturing overhead and eliminates moisture-related popcorning risk. |
| Gull-wing lead form | Visible solder joints enable AOI inspection and improve process yield in high-volume SMT lines. |
| High surge current rating | 760 A non-repetitive peak withstand capability - protects downstream circuitry from lightning-induced or inductive-switching transients. |
| RoHS-compliant matte-tin finish | e3 marking confirms lead-free plating compatible with Pb-free reflow profiles and long-term reliability requirements. |
Applications
| Industrial Power Supply Regulation | DC-DC Converter Feedback Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5376B | Through-hole DO-41 package; identical VZ, tolerance, and electrical specs; no RoHS compliance (Sn/Pb plating). | Requires axial-leaded PCB layout; unsuitable for high-density SMT production. | Select when legacy through-hole assembly is mandated or thermal mass of DO-41 improves low-frequency surge handling. |
| SMBJ5376B | J-bend DO-214AA package; same VZ and power rating but higher RθJA (110 °C/W); RoHS-compliant. | Lower thermal efficiency on FR4; requires larger copper area for equivalent power dissipation. | Select when existing DO-214AA footprint is fixed and gull-wing rework is not feasible. |
Compared with SMBG5376AE3/TR13, 1N5376B offers identical regulation performance but lacks SMT compatibility and RoHS compliance, while SMBJ5376B retains RoHS status but sacrifices thermal performance due to inferior junction-to-ambient conduction in the J-bend package.

FAQ
What is the Zener voltage tolerance of SMBG5376AE3/TR13?
The SMBG5376AE3/TR13 has a Zener voltage tolerance of ±10%, denoted by the "A" suffix in its part number. This means its actual breakdown voltage falls between 78.3 V and 95.7 V when measured at 15 mA test current and 25 °C. The tolerance is guaranteed across the full operating temperature range of –65 °C to +150 °C, and SMBG5376AE3/TR13 maintains this specification under JEDEC-compliant test conditions.
Does SMBG5376AE3/TR13 require dry packing before reflow soldering?
No, SMBG5376AE3/TR13 does not require dry packing prior to reflow. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at standard ambient conditions (≤30 °C / 60% RH) without baking. This eliminates moisture-related defects such as popcorn cracking during lead-free reflow, and SMBG5376AE3/TR13 is qualified for standard 260 °C, 10-second solder temperature exposure.
What is the maximum surge current rating for SMBG5376AE3/TR13?
The SMBG5376AE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 760 A, defined per an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1. SMBG5376AE3/TR13 delivers this surge capability while maintaining structural integrity and post-surge parameter stability, making it suitable for IEC 61000-4-5 compliant protection circuits.
How does the DO-215AA package of SMBG5376AE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5376AE3/TR13 features gull-wing leads that extend outward and downward, enabling visual solder joint inspection and lower profile mounting. In contrast, DO-214AA (used in SMBJ5376B) uses J-bend leads that curl under the body, resulting in higher RθJA (110 °C/W vs. 90 °C/W) and reduced thermal efficiency. SMBG5376AE3/TR13's gull-wing form also provides superior mechanical strength during board flexure and thermal cycling.
Is SMBG5376AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5376AE3/TR13 is fully compatible with lead-free reflow processes. Its "e3" suffix certifies RoHS-compliant matte-tin plating, and the device is qualified for peak solder temperatures up to 260 °C for 10 seconds per J-STD-020. The thermosetting epoxy body meets UL94V-0 flammability standards, and SMBG5376AE3/TR13 exhibits no delamination, cracking, or parametric shift when subjected to standard Pb-free reflow thermal profiles.
