Product details
Overview
SMBG5358AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 22 V, ±10% tolerance (A suffix), and maximum Zener current IZM of 75 mA at TL < 25 °C. It uses DO-215AA gull-wing package, delivers low dynamic impedance (3.5 Ω at IZT = 50 mA), and is rated for surge current up to 4.7 A (8.3 ms half-sine). It serves as precision voltage reference and overvoltage clamp in DC power supply regulation circuits.
For engineers reviewing the SMBG5358AE3/TR13 datasheet, SMBG5358AE3/TR13 pinout, SMBG5358AE3/TR13 application, or SMBG5358AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating, moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased breakdown mode with stable VZ regulation across wide current (IZK = 1.0 mA to IZM = 75 mA) and temperature (–65 °C to +150 °C) ranges. Its low RθJL enables effective heat transfer to PCB leads under sustained 5 W dissipation when lead temperature is maintained below 25 °C.
Zener impedance is specified at 3.5 Ω (measured at 1 kHz, 10% rms AC modulation on 50 mA DC bias), and reverse leakage IR is limited to ≤0.5 µA at VR = 15.8 V - confirming tight regulation near knee voltage and minimal standby loss in clamping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±10% at IZT = 50 mA - defines nominal regulation point with 2.2 V tolerance band for stable reference generation. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or lead heatsinking to sustain full rating. |
| Dynamic Impedance (ZZT) | 3.5 Ω at IZT = 50 mA - ensures minimal output voltage variation under load transients in feedback or protection circuits. |
| Max Surge Current (IZSM) | 4.7 A (8.3 ms half-sine) - provides robust transient overvoltage suppression without degradation. |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables direct thermal path to PCB traces, critical for reliability in high-power density layouts. |
| Moisture Sensitivity | Level 1 per J-STD-020B - eliminates dry-pack requirement and simplifies SMT handling and storage. |
| Forward Voltage (VF) | 1.2 V at IF = 1.0 A - supports bidirectional ESD/overvoltage protection when used with series resistor or in back-to-back configuration. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; anode and cathode terminals are accessible via two J-bend leads suitable for visual solder inspection and automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground node in reverse-bias regulation | Connected to lower-potential side of regulated circuit; must be routed with adequate current-carrying trace width for 75 mA continuous operation. |
| Cathode | Current exit terminal in forward bias; Zener voltage reference node in reverse bias | Banded end; connected to regulated rail or feedback node; requires low-inductance layout to preserve transient response during surge events. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5358B equivalence | Identical electrical characteristics and test methods - enables drop-in replacement in legacy designs qualified to MIL-PRF-19500/510. |
| RoHS-compliant matte-tin plating | e3 suffix confirms annealed tin finish meeting IPC-J-STD-006B - eliminates lead-based solder compatibility concerns and supports Pb-free reflow profiles. |
| Gull-wing lead geometry | DO-215AA footprint with visible solder joints - facilitates post-reflow AOI and reduces voiding risk compared to J-bend (DO-214AA) variants. |
| MSL Level 1 rating | No dry pack or floor life limitation - simplifies inventory control and eliminates bake-out steps prior to assembly. |
| High surge current capability | 4.7 A non-repetitive peak (8.3 ms) - exceeds IEC 61000-4-5 Level 3 surge immunity requirements for industrial power inputs. |
Applications
| DC Power Supply Regulation | Overvoltage Protection Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5358B | Same VZ (22 V), ±5% tolerance (B suffix), identical DO-215AA package, but Sn/Pb plating (non-RoHS). | Requires leaded solder process; not suitable for Pb-free manufacturing lines. | Select only if legacy SnPb assembly is mandated and RoHS compliance is waived. |
| SMBJ5358B | Same VZ and tolerance, but DO-214AA J-bend package; RθJA = 90 °C/W vs. 25 °C/W (RθJL) - lower thermal efficiency. | Higher junction temperature rise under same power; unsuitable for high-density layouts with limited copper area. | Prefer SMBG5358AE3/TR13 when thermal performance or AOI visibility is critical. |
Compared with 1N5358B and SMBJ5358B, SMBG5358AE3/TR13 uniquely combines RoHS compliance, gull-wing manufacturability, and superior junction-to-lead thermal resistance - making it optimal for new industrial designs requiring long-term supply continuity and Pb-free process alignment.

FAQ
What is the Zener voltage tolerance of SMBG5358AE3/TR13?
The SMBG5358AE3/TR13 has a Zener voltage tolerance of ±10%, denoted by the "A" suffix in the part number. This means its measured VZ at IZT = 50 mA falls within 19.8 V to 24.2 V at TL = 25 °C. The tolerance directly impacts regulation accuracy in feedback and reference applications, and must be accounted for in worst-case circuit analysis.
Does SMBG5358AE3/TR13 require dry packing before SMT assembly?
No, SMBG5358AE3/TR13 is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it has no floor life limitation and does not require dry packing or baking prior to reflow. This simplifies logistics and eliminates moisture-related defects such as popcorning during lead-free soldering.
What is the maximum continuous Zener current for SMBG5358AE3/TR13?
The maximum continuous Zener current (IZM) for SMBG5358AE3/TR13 is 75 mA when lead temperature (TL) is maintained below 25 °C. At higher TL, derating applies per the power derating curve - e.g., at TL = 75 °C, usable IZM drops to approximately 42 mA to stay within 5 W thermal limit.
How does the DO-215AA package of SMBG5358AE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5358AE3/TR13 features gull-wing leads enabling visible solder joints and lower RθJL (25 °C/W), while DO-214AA uses J-bend leads with higher RθJA (90 °C/W) and no direct lead thermal path. This makes DO-215AA preferable for thermally sensitive or AOI-dependent applications.
Is SMBG5358AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5358AE3/TR13 carries the "e3" suffix indicating RoHS-compliant matte-tin plating, qualified for standard Pb-free reflow profiles with peak temperatures up to 260 °C for 10 seconds. Its thermal resistance and moisture rating ensure reliability under JEDEC J-STD-020D conditions.
