Product details
Overview
SMBG5358C/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 regulator current of 75 mA. It operates in the DO-215AA gull-wing package and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5358C/TR13 datasheet, SMBG5358C/TR13 pinout, SMBG5358C/TR13 application, or SMBG5358C/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (4.7 A), reverse leakage performance at 15.8 V, and RoHS-compliant matte-tin plating compatibility with lead-free reflow.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, with specified Zener voltage measured at 50 mA (IZT) and characterized by low dynamic impedance (3.5 Ω) and tight ±2% voltage tolerance. Its thermal design relies on junction-to-lead conduction (RθJL = 25 °C/W) rather than ambient convection, requiring direct PCB copper thermal relief to leads.
The SMBG5358C/TR13 exhibits minimal voltage drift over temperature (−65 to +150 °C junction range) and maintains stable regulation across 10–100 mA operating current. It withstands non-repetitive 8.3 ms half-sine surge currents up to 4.7 A and meets MIL-STD-750 ESD immunity requirements without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±2% at 50 mA - ensures precise reference accuracy for feedback networks in switching regulators. |
| Power Dissipation | 5.0 W at TL < 25 °C - defines maximum continuous DC power handling with adequate lead heat sinking. |
| Dynamic Impedance (ZZT) | 3.5 Ω at IZT = 50 mA - determines output voltage stability under load transients in regulation circuits. |
| Max Regulator Current (IZM) | 75 mA - sets upper limit for safe DC bias current before thermal runaway risk increases. |
| Surge Current (IZSM) | 4.7 A (8.3 ms half-sine) - supports transient overvoltage clamping in surge-prone industrial inputs. |
| Reverse Leakage (IR) | 0.5 µA at 15.8 V - guarantees negligible standby current in high-impedance sensing or battery-backed circuits. |
| Junction Temp Range | −65 to +150 °C - enables operation in automotive engine compartments and industrial motor drives. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode only - no internal circuitry or control pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown terminal | Connected to regulated output node; must be held positive relative to anode during operation. |
| Anode | Reference terminal | Connected to ground or return path; serves as voltage reference point for Zener regulation. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables compatibility with Pb-free reflow profiles (260 °C, 10 s) without solderability degradation. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for assembly planning. |
| Gull-wing lead form (DO-215AA) | Provides visual solder joint inspection capability and mechanical strain relief on FR4 PCBs. |
| JEDEC 1N53xxB equivalent | Ensures drop-in replacement compatibility with legacy designs using axial 1N5358B parts. |
| Non-sensitive to ESD (MIL-STD-750 Method 1020) | Reduces need for handling precautions and in-circuit ESD protection components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5358B | Axial-leaded T-18 package; identical electrical 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 SMBG5358C/TR13 for surface-mount production; choose 1N5358B only for prototyping or legacy repair. |
| SMBJ5358C | DO-214AA J-bend package; same Zener voltage/tolerance but higher RθJL (30 °C/W vs. 25 °C/W). | Lower thermal performance limits continuous power to ~4.2 W at TL = 25 °C versus 5.0 W for SMBG5358C/TR13. | Prefer SMBG5358C/TR13 when thermal management is critical; SMBJ5358C acceptable for lower-power or intermittent duty. |
Compared with 1N5358B and SMBJ5358C, SMBG5358C/TR13 delivers superior thermal conduction (25 °C/W RθJL), visible gull-wing solder joints for AOI, and guaranteed RoHS compliance - making it optimal for volume SMT manufacturing of industrial and automotive power systems.

FAQ
What is the Zener voltage tolerance of SMBG5358C/TR13?
The SMBG5358C/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1, where SMBG5358B (±5%) and SMBG5358C (±2%) are explicitly differentiated. The 22 V nominal voltage is guaranteed between 21.56 V and 22.44 V at 50 mA test current and 30 °C lead temperature.
Does SMBG5358C/TR13 require dry packing due to moisture sensitivity?
No, SMBG5358C/TR13 does not require dry packing. Per the Mechanical and Packaging section on page 2 of the datasheet, its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking or dry pack. This eliminates floor-life tracking and pre-reflow baking steps in manufacturing.
What is the maximum surge current rating for SMBG5358C/TR13?
The SMBG5358C/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 4.7 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3. This value is derived from the device's 5 W power rating and 22 V Zener voltage, enabling robust transient suppression in 24 V industrial systems without external TVS diodes.
Is SMBG5358C/TR13 compatible with lead-free reflow soldering?
Yes, SMBG5358C/TR13 features RoHS-compliant annealed matte-tin plating and is rated for solder temperature of 260 °C for 10 seconds, per MIL-STD-750 Method 2026. Its DO-215AA gull-wing geometry also supports reliable wetting and void-free joints under standard Pb-free reflow profiles, as confirmed in the Mechanical and Packaging section.
How does the thermal resistance of SMBG5358C/TR13 compare to axial 1N5358B?
SMBG5358C/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, significantly lower than the 1N5358B's typical RθJL of 40–45 °C/W due to its gull-wing leadframe design. This allows SMBG5358C/TR13 to dissipate full 5 W power at lower lead temperatures, improving reliability in thermally constrained PCB layouts.
