Product details
Overview
SMBG5358CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 22 V, ±2% tolerance (C suffix), 3.5 Ω dynamic impedance at 50 mA test current, and maximum Zener current of 75 mA. It operates in the breakdown region to provide precise voltage regulation in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the SMBG5358CE3/TR13 datasheet, SMBG5358CE3/TR13 pinout, SMBG5358CE3/TR13 application, or SMBG5358CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (4.7 A peak), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse-biased avalanche breakdown. Its 22 V nominal Zener voltage is specified at 50 mA (IZT), with dynamic impedance measured at 1 kHz AC modulation superimposed on DC bias.
The DO-215AA gull-wing package enables visible solder joints and supports 5 W power dissipation at TL < 25 °C, derating linearly above that temperature per the published curve. Junction-to-lead thermal resistance is 25 °C/W, enabling effective heat transfer to PCB copper when mounted per recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±2% at 50 mA - ensures tight regulation in feedback loops requiring stable reference under varying load. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports high-energy transient clamping without external heatsink when lead-temperature controlled. |
| Dynamic Impedance (ZZT) | 3.5 Ω at IZT = 50 mA - minimizes output voltage variation across operating current range in precision regulation. |
| Max Surge Current (IZSM) | 4.7 A (8.3 ms half-sine) - withstands common-line surges and ESD transients in industrial power inputs. |
| Junction Temp Range | –65 to +150 °C - suitable for automotive under-hood and industrial control environments with wide ambient swings. |
| Thermal Resistance RθJL | 25 °C/W - allows direct thermal path to PCB copper pour, critical for sustained 5 W operation in compact layouts. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during operation. Leads are RoHS-compliant annealed matte-tin plated for solderability per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Positive terminal in reverse-bias operation | Connected to regulated rail or feedback node; polarity reversal causes forward conduction and loss of regulation. |
| Anode (unbanded end) | Reference/ground terminal | Tied to system ground or error amplifier reference; establishes Zener voltage drop direction across terminals. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5358B equivalent | Identical electrical specs and test methods - enables drop-in replacement for legacy through-hole designs using adapter footprints. |
| Moisture Sensitivity Level 1 | No dry pack required - eliminates baking step before reflow, reducing manufacturing cycle time and cost. |
| Gull-wing lead form | Visible solder joints - enables automated optical inspection (AOI) and improves process yield in high-volume SMT lines. |
| Non-ESD-sensitive | Qualified per MIL-STD-750 Method 1020 - eliminates need for ESD handling protocols during board assembly and testing. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Precision voltage reference establishing error threshold for PWM controller.

Use Scenario: Clamps transient spikes on 24 V industrial I/O lines exposed to inductive kickback. IC Role / Device Role / Timing Role: Shunt protector diverting excess energy to ground before downstream ICs exceed absolute max ratings. Use Value: 4.7 A surge rating handles 100 A/µs edge rates per IEC 61000-4-5 Level 3, preventing latch-up in PLC modules. |
| DC-DC Converter Reference | Automotive Body Control Module |
Use Scenario: Provides stable 22 V reference for adjustable buck regulator controlling LED driver current. IC Role / Device Role / Timing Role: Voltage setpoint generator defining output regulation point independent of input ripple.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5358B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs. | Requires axial-leaded PCB layout; not suitable for high-density SMT assemblies. | Select when retrofitting legacy designs or where manual repair access is prioritized over board space. |
| SMBJ5358B | J-bend leads (DO-214AA); same electrical specs but higher RθJA (100 °C/W vs. 90 °C/W). | Lower thermal performance in still-air environments; requires larger copper area for equivalent power handling. | Select when existing J-bend footprint is fixed and thermal margin exceeds 10 °C at full 5 W load. |
Compared with SMBG5358CE3/TR13, 1N5358B offers identical regulation performance but demands through-hole assembly, while SMBJ5358B fits J-bend land patterns but sacrifices 10 °C/W in junction-to-ambient thermal resistance-making SMBG5358CE3/TR13 optimal for space-constrained, thermally demanding SMT applications.

FAQ
What is the Zener voltage tolerance of SMBG5358CE3/TR13?
The "C" suffix in SMBG5358CE3/TR13 denotes ±2% Zener voltage tolerance at 50 mA test current. This means the actual VZ falls between 21.56 V and 22.44 V when measured at TL = 25 °C, supporting precision regulation in feedback networks where tight voltage setpoints are required.
Does SMBG5358CE3/TR13 require dry packing before reflow soldering?
No, SMBG5358CE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored and processed without dry packing or baking. This eliminates pre-reflow desiccation steps, reducing manufacturing overhead and avoiding potential damage from moisture-induced popcorning.
What is the maximum non-repetitive surge current rating for SMBG5358CE3/TR13?
SMBG5358CE3/TR13 is rated for 4.7 A peak non-repetitive surge current (IZSM) under an 8.3 ms half-sine waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet and applies directly to the SMBG5358B variant group including the CE3/TR13 version.
How does the DO-215AA package of SMBG5358CE3/TR13 differ from DO-214AA?
The DO-215AA package used by SMBG5358CE3/TR13 features gull-wing leads for visible solder joints and lower profile mounting, whereas DO-214AA (used in SMBJ53xx) uses J-bend leads. Both are surface-mount, but DO-215AA provides better AOI capability and slightly improved thermal resistance junction-to-lead (25 °C/W vs. 30 °C/W typical for DO-214AA).
Is SMBG5358CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5358CE3/TR13 uses RoHS-compliant matte-tin plating and is qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. The device meets JEDEC J-STD-020 requirements and is rated for peak solder temperature exposure without degradation of Zener characteristics or mechanical integrity.
