Product details
Overview
SMBG5359CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 24 V, ±2% tolerance (suffix C), RoHS-compliant matte-tin plating, and DO-215AA gull-wing package. It regulates voltage across broad current and temperature ranges in power supply reference and overvoltage protection circuits.
For engineers reviewing the SMBG5359CE3/TR13 datasheet, SMBG5359CE3/TR13 pinout, SMBG5359CE3/TR13 application, or SMBG5359CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current rating (4.4 A), thermal resistance (90 °C/W on FR4), and moisture sensitivity level (MSL 1).
Technical Context
This device operates in reverse-biased breakdown mode, maintaining stable 24 V regulation at IZT = 50 mA. Its dynamic impedance is 3.5 Ω at IZT and 27 Ω at 1 mA knee current (ZZK), ensuring low voltage variation under load transients.
Designed for surface-mount high-density PCBs, it features visible gull-wing solder joints, UL94V-0 epoxy encapsulation, and withstands 260 °C soldering for 10 s. Polarity is marked by cathode band; operation requires banded end positive relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24 V ±2% at 50 mA - precise reference for feedback loops in DC-DC converters. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - supports sustained regulation in compact heatsink-limited layouts. |
| Max Regulator Current (IZM) | 100 mA - defines maximum continuous DC current before thermal derating. |
| Surge Current (IZSM) | 4.4 A (8.3 ms half-sine) - handles transient overvoltage events without failure. |
| Dynamic Impedance (ZZT) | 3.5 Ω at 50 mA - minimizes output voltage shift during load current changes. |
| Reverse Leakage (IR) | 0.5 µA at 19.4 V - ensures negligible standby current in battery-powered systems. |
| Thermal Resistance (RθJA) | 90 °C/W on FR4 (1 oz Cu) - enables thermal design with standard PCB copper area. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by molded band; terminals are anode (unbanded end) and cathode (banded end). Moisture sensitivity level is MSL 1 - no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground in Zener regulation | Connected to lower-potential node (e.g., GND or return path) when used as shunt regulator. |
| Cathode | Current exit terminal in forward bias; regulated output node in Zener mode | Banded end connects to input rail; maintains 24 V between cathode and anode under reverse bias. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5359B | Same 24 V ±5%, axial-leaded T-18 package, non-RoHS Sn/Pb plating | Requires through-hole assembly; unsuitable for high-density SMT boards | Select for legacy repair or prototyping where leaded mounting is acceptable. |
| SMBJ5359B | Same 24 V ±5%, DO-214AA J-bend package, identical RoHS option available | Lower surge rating (4.1 A vs. 4.4 A); slightly higher RθJA (100 °C/W) | Select when footprint compatibility with SMBJ series is required and 0.3 A surge margin is acceptable. |
Compared with SMBG5359CE3/TR13, 1N5359B offers identical regulation but lacks SMT compatibility and RoHS compliance, while SMBJ5359B matches the surface-mount form factor but trades 0.3 A surge capacity and 10 °C/W higher thermal resistance for J-bend lead geometry.

FAQ
What is the Zener voltage tolerance for SMBG5359CE3/TR13?
The SMBG5359CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its measured VZ falls within 23.52 V to 24.48 V at 50 mA test current and 25 °C, enabling tighter regulation than ±5% (B) or ±10% (A) variants. The SMBG5359CE3/TR13 achieves this accuracy through post-package sorting and screening per Microsemi's T4-LDS-0246-1 specification.
Does SMBG5359CE3/TR13 require dry packing before reflow?
No, SMBG5359CE3/TR13 does not require dry packing prior to reflow soldering. It carries IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates preconditioning steps in SMT lines and reduces handling risk-confirmed in the "Mechanical and Packaging" section of the Microsemi T4-LDS-0246-1 datasheet for SMBG5359CE3/TR13.
What is the maximum surge current rating for SMBG5359CE3/TR13?
The SMBG5359CE3/TR13 has a maximum non-repetitive peak surge current (IZSM) of 4.4 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet. This value reflects its ability to absorb transient energy without parametric shift or failure, making SMBG5359CE3/TR13 suitable for clamping inductive spikes in industrial controls.
How does the thermal resistance of SMBG5359CE3/TR13 affect PCB layout?
The SMBG5359CE3/TR13 has RθJA = 90 °C/W when mounted on FR4 with 1 oz copper and Microsemi's recommended pad layout. To maintain TJ ≤ 150 °C at full 5 W dissipation, ≥5.5 cm² of 1 oz copper pour must connect to both terminals. Layouts ignoring this requirement risk thermal runaway-verified by the derating curve in Figure 1 of the SMBG5359CE3/TR13 datasheet.
Is SMBG5359CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5359CE3/TR13 is fully compatible with lead-free reflow. Its matte-tin (e3) plating supports peak temperatures up to 260 °C for 10 seconds, meeting JEDEC J-STD-020D requirements. The device passes solderability testing per MIL-STD-750 Method 2026, and its UL94V-0 epoxy body remains stable under standard Pb-free thermal profiles-explicitly confirmed in the "Mechanical and Packaging" section for SMBG5359CE3/TR13.
