Product details
Overview
SMBG5375A/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 82 V, ±10% tolerance (A-suffix), 15 mA test current (IZT), and 65 Ω dynamic impedance (ZZT) at IZT. It operates from –65 °C to +150 °C, features DO-215AA gull-wing package, and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5375A/TR13 datasheet, SMBG5375A/TR13 pinout, SMBG5375A/TR13 application, or SMBG5375A/TR13 equivalent, key selection criteria include Zener voltage tolerance, maximum surge current (IZSM = 720 A), thermal resistance (RθJL = 25 °C/W), and RoHS compliance status (non-RoHS, blank suffix).
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown, delivering stable regulation across wide current (15 mA IZT to 58 mA IZM) and temperature ranges. Its low dynamic impedance (65 Ω) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package enables visible solder joints and supports high-density PCB layouts. Thermal performance is defined by RθJL = 25 °C/W (junction-to-lead) and RθJA = 90 °C/W (junction-to-ambient on FR4), enabling reliable 5 W operation only with adequate lead heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±10% - regulates at 73.8–90.2 V under 15 mA DC bias; defines clamping threshold in protection circuits. |
| Test Current (IZT) | 15 mA - standardized bias point where VZ and ZZT are guaranteed; sets minimum operating current for stable regulation. |
| Dynamic Impedance (ZZT) | 65 Ω - small-signal AC impedance at 15 mA; determines output voltage ripple rejection and regulation sensitivity. |
| Max Regulator Current (IZM) | 58 mA - maximum continuous DC current at TL < 25 °C; limits power dissipation to 5.0 W without thermal derating. |
| Surge Current (IZSM) | 720 A - non-repetitive 8.3 ms half-sine peak; enables transient overvoltage suppression (e.g., lightning/ESD events). |
| Junction Temp Range | –65 °C to +150 °C - supports industrial and automotive under-hood environments without derating. |
| Thermal Resistance (RθJL) | 25 °C/W - junction-to-lead path dominates thermal management; requires short, wide copper traces to heatsink. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals are formed by symmetrical gull-wing leads extending from opposite sides of the molded epoxy body. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node | Connected to circuit ground or lower-potential rail; forms return path during forward bias or Zener regulation. |
| Cathode | Reverse breakdown terminal / Regulated output node | Banded end; connected to voltage node requiring stabilization; carries full Zener current during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5375A equivalent | Identical electrical specs and test methods to legacy axial 1N5375A - enables drop-in replacement in legacy designs. |
| Gull-wing lead form | Visible solder joints enable AOI inspection and reduce tombstoning risk on fine-pitch PCBs. |
| Level 1 moisture sensitivity | No baking or dry pack required before reflow - simplifies SMT line handling and reduces process cost. |
| High surge capability | 720 A non-repetitive surge rating supports IEC 61000-4-5 Level 4 compliance in AC/DC front-end protection. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375A | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM specs; no gull-wing geometry. | Requires through-hole assembly and larger board area; unsuitable for high-density SMT layouts. | Select when legacy through-hole manufacturing or manual prototyping is required. |
| SMBG5375B | Same DO-215AA package but ±5% VZ tolerance (B-suffix); 50 Ω ZZT at 15 mA; 55 mA IZM. | Tighter regulation needed for precision references; lower dynamic impedance improves ripple rejection. | Select when system-level VZ stability requirement exceeds ±10%, e.g., in closed-loop feedback with <1% output tolerance. |
Compared with SMBG5375A/TR13, 1N5375A offers identical regulation performance but mandates through-hole assembly, while SMBG5375B delivers tighter voltage control and lower impedance at the cost of reduced surge margin (620 A vs. 720 A) and higher unit cost.

FAQ
What is the Zener voltage tolerance of SMBG5375A/TR13?
The SMBG5375A/TR13 has a Zener voltage tolerance of ±10%, meaning its regulated voltage falls between 73.8 V and 90.2 V when tested at 15 mA (IZT) and 25 °C. This tolerance is encoded by the "A" suffix in the part number and is verified per JEDEC test conditions specified in Microsemi's T4-LDS-0246-1 datasheet.
Does SMBG5375A/TR13 require dry packing before reflow soldering?
No, SMBG5375A/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, which means it can be stored and processed without dry packing or baking. This eliminates pre-reflow handling steps and reduces manufacturing overhead in SMT lines.
What is the maximum continuous Zener current for SMBG5375A/TR13?
The maximum continuous Zener current (IZM) for SMBG5375A/TR13 is 58 mA when lead temperature (TL) is maintained below 25 °C. At ambient temperature (TA = 25 °C) on a standard FR4 board, derating applies, limiting usable current to approximately 1.38 W / 82 V ≈ 16.8 mA unless enhanced thermal management is implemented.
How does the DO-215AA package of SMBG5375A/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5375A/TR13 features gull-wing leads for visible solder joints and improved coplanarity control, whereas DO-214AA uses J-bend leads. Both are surface-mount, but DO-215AA provides better optical inspection capability and lower tombstoning risk due to symmetric lead geometry and tighter lead pitch control.
Is SMBG5375A/TR13 RoHS compliant?
No, SMBG5375A/TR13 is not RoHS compliant. The absence of the "e3" suffix indicates tin-lead (Sn/Pb) plating. For RoHS-compliant versions, Microsemi offers SMBG5375B-e3 (±5% tolerance) or SMBG5375C-e3 (±2% tolerance), both with matte-tin finish meeting EU Directive 2011/65/EU requirements.
