Product details
Overview
SMBG5380C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 120 V, ±2% tolerance (C suffix), 10 mA test current (IZT), and dynamic impedance of 170 Ω at IZT - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5380C/TR13 datasheet, SMBG5380C/TR13 pinout, SMBG5380C/TR13 application, or SMBG5380C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1150 A), thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, 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 (10 mA to 5.5 mA IZM) and temperature (–65 °C to +150 °C) ranges. Its low dynamic impedance (170 Ω) ensures minimal voltage variation under load transients.
The SMBG5380C/TR13 uses a void-free thermosetting epoxy case (UL94V-0), cathode band polarity marking, and gull-wing leads solderable per MIL-STD-750 method 2026 - enabling visible solder joint inspection and reliable reflow assembly on FR4 boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 120 V ±2% at 10 mA - enables tight regulation in 115–125 V reference paths |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via lead conduction, not ambient convection |
| Dynamic Impedance (ZZT) | 170 Ω at 10 mA - limits output voltage shift to ≤1.7 V per 10 mA load change |
| Max Regulator Current (IZM) | 5.5 mA - sets upper bound for continuous DC bias in feedback networks |
| Surge Current (IZSM) | 1150 A (8.3 ms half-sine) - withstands lightning-induced transients in AC/DC front-ends |
| Junction-to-Lead RθJL | 25 °C/W - supports thermal design using PCB copper pour connected to cathode/anode leads |
| Reverse Leakage (IR) | 0.5 µA at 91.2 V - ensures negligible error current in high-impedance sensing nodes |
Pinout & Package
DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by molded band; device operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return path; carries full regulator current |
| Cathode | Regulated output node | Provides stable 120 V reference; must be routed with controlled impedance in feedback paths |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5380B equivalent | Direct functional replacement for legacy axial 1N5380B with identical VZ, IZT, and ZZT |
| RoHS-compliant matte-tin plating | Enables Pb-free reflow without solderability degradation or whisker risk |
| Moisture sensitivity Level 1 | No dry pack or baking required before assembly - reduces manufacturing overhead |
| Gull-wing lead geometry | Permits visual solder joint inspection and eliminates tombstoning on fine-pitch layouts |
| High surge current rating | 1150 A peak withstand capability simplifies transient protection design in AC line stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5380B | Axial-leaded T-18 package; same VZ, IZT, ZZT, but higher RθJA (125 °C/W) | Requires through-hole mounting and larger board area; unsuitable for automated SMT lines | Select when legacy through-hole assembly or manual prototyping is required |
| SMBJ5380C | DO-214AA J-bend package; identical electrical specs but 35 °C/W RθJL and no gull-wing visibility | Lacks visual solder inspection capability; slightly lower thermal performance in lead-conducted cooling | Select when DO-214AA footprint is already standardized and gull-wing inspection is not critical |
Compared with SMBG5380C/TR13, 1N5380B offers identical regulation but demands manual assembly and poorer thermal conduction, while SMBJ5380C matches SMT compatibility but sacrifices solder-joint visibility and thermal efficiency - making SMBG5380C/TR13 optimal for high-reliability, automated, thermally constrained designs.

FAQ
What is the Zener voltage tolerance of SMBG5380C/TR13?
The "C" suffix in SMBG5380C/TR13 denotes ±2% Zener voltage tolerance at 10 mA test current. This is tighter than the ±5% (B suffix) or ±10% (A suffix) options, making SMBG5380C/TR13 suitable for applications demanding high reference accuracy without post-production calibration.
Does SMBG5380C/TR13 require dry packing before reflow soldering?
No. SMBG5380C/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it can be stored and processed without dry packing or baking - reducing handling steps and eliminating moisture-related popcorning risk during reflow.
What is the maximum surge current rating for SMBG5380C/TR13?
SMBG5380C/TR13 is rated for 1150 A peak non-repetitive surge current (IZSM) with an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet and supports robust transient suppression in AC line and DC bus protection.
How does the DO-215AA package of SMBG5380C/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5380C/TR13 provides visible solder joints and lower thermal resistance (25 °C/W junction-to-lead) versus the DO-214AA J-bend variant (35 °C/W). This improves thermal performance and enables optical inspection - critical for high-reliability manufacturing.
Is SMBG5380C/TR13 RoHS compliant?
Yes. The "e3" designation is implied by the "C" suffix in the full Microsemi nomenclature, and the datasheet explicitly states RoHS-compliant matte-tin plating is used for SMBG5380C/TR13 - meeting EU Directive 2011/65/EU requirements without lead or hazardous substances.
