Product details
Overview
SMBG5372CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 62 V, ±2% tolerance (C suffix), rated test current of 20 mA, dynamic impedance of 42 Ω at IZT, and maximum Zener current of 400 mA. It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial and telecom power systems.
For engineers reviewing the SMBG5372CE3/TR13 datasheet, SMBG5372CE3/TR13 pinout, SMBG5372CE3/TR13 application, or SMBG5372CE3/TR13 equivalent, this page delivers verified electrical specs, DO-215AA gull-wing package details, JEDEC 1N5372B-compliant performance, thermal derating behavior, and RoHS-compliant matte-tin plating confirmation.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, maintaining stable 62 V regulation across 1 mA to 400 mA operating current. Its 42 Ω dynamic impedance at 20 mA ensures minimal voltage deviation under load transients.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it achieves 25 °C/W junction-to-lead thermal resistance and withstands 260 °C solder reflow per MIL-STD-750. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±2% at 20 mA - precise regulation point for 60–64 V system clamping |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management above ambient |
| Dynamic Impedance (ZZT) | 42 Ω at IZT = 20 mA - low AC impedance ensures tight voltage stability under ripple |
| Max Zener Current (IZM) | 400 mA - supports high-energy transient suppression without degradation |
| Reverse Leakage (IR) | 0.5 µA at 47.1 V - negligible standby current in high-impedance bias networks |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct lead heat conduction to PCB copper for sustained 5 W operation |
| Surge Current (IZSM) | 400 A (8.3 ms half-sine) - handles lightning-induced surges in telecom line protection |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only - no internal connections beyond the two leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal in reverse-bias operation | Connected to regulated rail or voltage reference node; polarity must be observed to avoid forward conduction |
| Anode | Ground or return path | Typically tied to system ground or lower-potential node; forms current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5372B equivalence | Identical electrical characteristics and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free finish compliant with IPC-J-STD-020B Level 1 moisture handling |
| Gull-wing lead form | DO-215AA package enables visual solder joint inspection and reliable reflow yield on fine-pitch layouts |
| High surge capability | 400 A non-repetitive surge rating supports IEC 61000-4-5 Level 4 compliance in AC/DC front-end protection |
| Stable voltage vs. temperature | ±0.075%/°C typical TC - maintains regulation accuracy across –65 °C to +150 °C junction range |
Applications
| Switch-Mode Power Supply Feedback | Telecom Line Surge Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5372BRLG | Same 62 V ±2%, 5 W, DO-41 axial package; higher RθJA (125 °C/W) limits PCB power density | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs | Select when legacy through-hole compatibility or manual repairability is prioritized over space efficiency |
| SMBJ5372B | Same 62 V ±2%, 5 W, but DO-214AA (J-bend) package; identical RθJL (25 °C/W) and surge rating | Compatible with same PCB thermal design but different footprint; no visual solder inspection capability | Select when existing DO-214AA footprint reuse is required; verify pad layout matches J-bend geometry |
Compared with SMBG5372CE3/TR13, 1N5372BRLG trades SMT manufacturability for axial serviceability, while SMBJ5372B retains surface-mount benefits but sacrifices gull-wing visual inspection - all three share identical Zener regulation performance and surge immunity.

FAQ
What is the Zener voltage tolerance of SMBG5372CE3/TR13?
The SMBG5372CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This means its measured VZ falls between 60.76 V and 63.24 V at the specified test current of 20 mA, enabling tighter regulation than ±5% or ±10% variants in precision feedback paths.
Does SMBG5372CE3/TR13 require dry packing before PCB assembly?
No, SMBG5372CE3/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 desiccant or humidity-controlled packaging - simplifying inventory and assembly logistics.
What is the maximum surge current rating for SMBG5372CE3/TR13?
The SMBG5372CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 400 A, defined as an 8.3 ms half-sine waveform. This rating supports compliance with IEC 61000-4-5 surge immunity testing in telecom and industrial equipment designs.
How does the DO-215AA package of SMBG5372CE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5372CE3/TR13 uses gull-wing leads for visible solder joints and improved reflow yield, whereas DO-214AA uses J-bend leads. Both share identical thermal resistance (25 °C/W RθJL) and power rating, but DO-215AA enables optical inspection - critical for automotive and medical manufacturing.
Is SMBG5372CE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5372CE3/TR13 features RoHS-compliant annealed matte-tin plating (e3 suffix) and is qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds, meeting IPC/JEDEC J-STD-020B requirements without solderability degradation.
