Product details
Overview
SMBG5350C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 13 V, ±2% tolerance (C suffix), and maximum Zener current IZM of 7.0 mA at TL < 25 °C - used for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation in industrial DC-DC converters.
For engineers reviewing the SMBG5350C/TR13 datasheet, SMBG5350C/TR13 pinout, SMBG5350C/TR13 application, or SMBG5350C/TR13 equivalent, key selection criteria include its DO-215AA gull-wing package, 2.5 Ω dynamic impedance at 100 mA, 1.0 µA reverse leakage at 10.1 V, and compliance with MIL-STD-750 ESD robustness testing.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across wide current (100 mA test point) and temperature (-65 °C to +150 °C) ranges. Its low dynamic impedance (2.5 Ω) ensures minimal voltage variation under load transients, while thermal resistance RθJL = 25 °C/W enables reliable 5 W dissipation with proper lead heat sinking.
The SMBG5350C/TR13 uses a void-free UL94V-0 epoxy body with matte-tin RoHS-compliant plating, cathode band polarity marking, and JEDEC 1N5350B-equivalent electrical characteristics - validated per Microsemi T4-LDS-0246-1 Rev. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±2% at IZT = 100 mA - defines regulated output voltage with tight tolerance for feedback accuracy. |
| Test Current (IZT) | 100 mA - standard operating point where VZ and dynamic impedance are specified. |
| Dynamic Impedance (ZZT) | 2.5 Ω - low AC impedance ensures stable regulation during fast load changes. |
| Max Reverse Leakage (IR) | 1.0 µA at VR = 10.1 V - confirms low standby power loss in high-impedance bias networks. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or lead conduction. |
| Junction Temperature Range | -65 °C to +150 °C - supports operation in harsh industrial and automotive under-hood environments. |
| Surge Current (IZSM) | 7.0 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation. |
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 |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to voltage source input; maintains fixed potential relative to anode during breakdown. |
| Anode | Reference/return node | Typically grounded or connected to lower-potential rail; completes current path through Zener junction. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5350B equivalence | Identical electrical specs and test methods - enables drop-in replacement in legacy designs. |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack required before reflow. |
| Gull-wing lead form | Enables visual solder joint inspection and high-density PCB layout on FR4 with 1 oz Cu. |
| ESD robustness | Non-sensitive per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in many applications. |
| High surge current rating | 7.0 A non-repetitive peak (8.3 ms) - protects downstream circuitry from line transients without derating. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5350B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IR specs but higher RθJA (125 °C/W vs. 90 °C/W). | Requires through-hole mounting and larger board area; unsuitable for high-density SMT layouts. | Select when legacy through-hole assembly or manual prototyping is required. |
| SMBJ5350C | DO-214AA J-bend package; same VZ, tolerance, and electrical specs but different thermal profile (RθJL = 30 °C/W). | Compatible with automated pick-and-place but offers lower thermal performance than SMBG's gull-wing leads. | Choose when existing DO-214AA footprint reuse is prioritized over optimal thermal conduction. |
Compared with SMBG5350C/TR13, 1N5350B lacks surface-mount compatibility and thermal efficiency, while SMBJ5350C trades off lead thermal resistance for footprint flexibility - making SMBG5350C/TR13 optimal for space-constrained, thermally demanding SMT designs requiring JEDEC-equivalent reliability.

FAQ
What is the Zener voltage tolerance of SMBG5350C/TR13?
The "C" suffix in SMBG5350C/TR13 indicates a ±2% Zener voltage tolerance at IZT = 100 mA and TL = 25 °C, corresponding to a guaranteed range of 12.74 V to 13.26 V - tighter than the ±5% (B) or ±10% (A) variants for improved regulation accuracy.
Does SMBG5350C/TR13 require dry packing before reflow soldering?
No - SMBG5350C/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and processed without dry pack or baking, even after extended ambient exposure, due to its void-free UL94V-0 epoxy encapsulation.
What is the maximum surge current rating for SMBG5350C/TR13?
SMBG5350C/TR13 is rated for 7.0 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform, verified per Microsemi T4-LDS-0246-1 - enabling robust protection against common automotive and industrial transients.
How does the DO-215AA package of SMBG5350C/TR13 differ from DO-214AA?
The DO-215AA gull-wing package of SMBG5350C/TR13 provides lower thermal resistance (RθJL = 25 °C/W) versus DO-214AA's J-bend leads (RθJL = 30 °C/W), and allows direct visual inspection of solder joints - unlike DO-214AA's hidden underside terminations.
Is SMBG5350C/TR13 electrically equivalent to 1N5350B?
Yes - SMBG5350C/TR13 is explicitly stated in Microsemi documentation as electrically equivalent to JEDEC 1N5350B, with identical VZ, IZT, ZZT, IR, and surge ratings, differing only in package type and RoHS compliance (e3 plating).
