Product details
Overview
SMBG5372C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 62 V, ±2% tolerance (C suffix), 20 mA test current, and 76 Ω dynamic impedance at IZT; used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5372C/TR13 datasheet, SMBG5372C/TR13 pinout, SMBG5372C/TR13 application, or SMBG5372C/TR13 equivalent, key selection criteria include Zener voltage tolerance, surge current rating (400 A), thermal resistance (25 °C/W junction-to-lead), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable reference voltage across wide current (20 mA to 2.1 A) and temperature (-65 to +150 °C) ranges. Its low dynamic impedance (76 Ω at 20 mA) ensures minimal voltage variation under load transients.
The SMBG5372C/TR13 uses a void-free thermosetting epoxy case (UL94V-0), matte-tin RoHS-compliant plating, and cathode band polarity marking. It meets MIL-STD-750 ESD robustness requirements and has IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 62 V ±2% at 20 mA - precise regulation point for 60–64 V systems |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on lead frame for full rating |
| Dynamic Impedance (ZZT) | 76 Ω at 20 mA - low AC impedance improves regulation stability under varying load |
| Max Surge Current (IZSM) | 400 A (8.3 ms half-sine) - withstands transient overvoltage events without failure |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer to PCB copper via gull-wing leads |
| Reverse Leakage (IR) | 0.5 µA at 47.1 V - negligible standby current in high-impedance bias networks |
| Junction Temp Range | -65 to +150 °C - supports operation in automotive under-hood and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5372B | Axial-leaded T-18 package; same 62 V ±2%, 5 W rating, but higher RθJA (125 °C/W) | Requires through-hole assembly; unsuitable for high-density SMT layouts | Select when legacy through-hole design or manual prototyping is required |
| SMBJ5372C | DO-214AA J-bend package; identical electrical specs but 30% higher RθJA (117 °C/W) due to smaller thermal pad area | Compatible footprint but reduced thermal performance under sustained load | Select only if DO-214AA is already standardized in BOM and board layout allows enhanced copper pour |
Compared with SMBG5372C/TR13, 1N5372B offers identical regulation but lacks surface-mount compatibility, while SMBJ5372C sacrifices thermal efficiency for footprint interchangeability-making SMBG5372C/TR13 optimal for space-constrained, thermally demanding SMT applications.

FAQ
What is the Zener voltage tolerance of SMBG5372C/TR13?
The SMBG5372C/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its breakdown voltage is guaranteed between 60.76 V and 63.24 V when measured at 20 mA test current and 25 °C ambient. This tighter tolerance supports precision regulation where minimal output deviation is critical, such as in feedback networks of regulated DC-DC converters.
Does SMBG5372C/TR13 require dry packing before reflow soldering?
No, SMBG5372C/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored and processed indefinitely at standard factory humidity without baking. This eliminates pre-reflow bake cycles and simplifies manufacturing logistics for high-volume SMT lines handling SMBG5372C/TR13.
What is the maximum continuous Zener current for SMBG5372C/TR13?
The maximum continuous Zener current (IZM) for SMBG5372C/TR13 is 2.1 A when mounted with proper thermal management on a lead frame at TL < 25 °C. At 25 °C ambient on FR4 with recommended footprint, derated power limits IZM to approximately 1.38 A. This value is calculated per Note 3 in the datasheet using P/VZM, where VZM = 62 V × 1.02 = 63.24 V.
How does the DO-215AA package of SMBG5372C/TR13 improve manufacturability?
The DO-215AA gull-wing package of SMBG5372C/TR13 enables visible solder joint inspection after reflow, supports automated optical inspection (AOI), and provides superior thermal conduction (RθJL = 25 °C/W) compared to J-bend alternatives. Its 0.1 g weight and UL94V-0 epoxy body also meet stringent reliability requirements for automotive and industrial applications where SMBG5372C/TR13 is deployed.
Is SMBG5372C/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5372C/TR13 is RoHS compliant with annealed matte-tin plating and rated for solder temperatures up to 260 °C for 10 seconds, fully supporting industry-standard lead-free reflow profiles (e.g., IPC-J-STD-020). Its thermal resistance and epoxy body integrity have been validated under these conditions, ensuring reliable interconnect formation without delamination or parametric shift in SMBG5372C/TR13 performance.
