Product details
Overview
SMBG5362B/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal Zener voltage of 28 V, ±5% tolerance (B suffix), 6.0 Ω dynamic impedance at 50 mA test current, and maximum regulator current of 130 mA. It operates across –65 °C to +150 °C junction temperature and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5362B/TR13 datasheet, SMBG5362B/TR13 pinout, SMBG5362B/TR13 application, or SMBG5362B/TR13 equivalent, key selection factors include its DO-215AA gull-wing package, 28 V Zener voltage with tight 5% tolerance, 5 W power rating at lead temperature <25 °C, low dynamic impedance, and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown, maintaining stable output voltage under varying load and temperature conditions. Its 28 V Zener voltage is specified at IZT = 50 mA, with dynamic impedance measured at 6.0 Ω using 10% rms ac modulation superimposed on dc bias.
The SMBG5362B/TR13 uses a void-free thermosetting epoxy case (UL94V-0), gull-wing leads with annealed matte-tin plating, and features moisture sensitivity level 1-no dry pack required. Thermal resistance is 25 °C/W junction-to-lead and 90 °C/W junction-to-ambient on FR4 with recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±5% at IZT = 50 mA - defines precise regulation point for feedback and clamping |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or heatsink |
| Dynamic Impedance (ZZT) | 6.0 Ω at IZT = 50 mA - ensures minimal voltage variation under load transients |
| Maximum Regulator Current (IZM) | 130 mA - sets upper limit for continuous Zener conduction without thermal runaway |
| Reverse Leakage (IR) | 0.5 µA at VR = 21.2 V - guarantees low standby power loss in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJL) | 25 °C/W - enables accurate junction temperature estimation from lead temperature measurement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362B | Same 28 V ±5%, 5 W rating, but axial DO-41 package with higher RθJA (125 °C/W) | Requires through-hole assembly and larger board area; less suitable for high-density SMT layouts | Select when legacy through-hole compatibility or manual prototyping is prioritized over miniaturization |
| SMBJ5362B | Identical electrical specs but J-bend DO-214AA package; slightly higher RθJA (95 °C/W) and different pad layout | Compatible with standard SMB footprint but not gull-wing reflow profile; may require stencil adjustment | Select when existing DO-214AA tooling exists or when gull-wing inspection capability is unavailable |
Compared with 1N5362B and SMBJ5362B, SMBG5362B/TR13 delivers identical regulation performance in a gull-wing DO-215AA package optimized for automated optical inspection, lower thermal resistance to lead, and zero dry-pack handling-making it ideal for high-reliability SMT production of industrial power systems.

FAQ
What is the Zener voltage tolerance of SMBG5362B/TR13?
The "B" suffix in SMBG5362B/TR13 indicates a ±5% Zener voltage tolerance. At 28 V nominal, this corresponds to a guaranteed range of 26.6 V to 29.4 V when measured at IZT = 50 mA and TL = 25 °C. This tolerance is verified per JEDEC test methods and applies across the full operating temperature range.
Does SMBG5362B/TR13 require dry packing before reflow soldering?
No, SMBG5362B/TR13 has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30 °C/60% RH without dry packing. The void-free UL94V-0 epoxy body and matte-tin plating eliminate popcorning risk during standard lead-free reflow profiles.
What is the maximum surge current rating for SMBG5362B/TR13?
SMBG5362B/TR13 is rated for a non-repetitive peak surge current (IZSM) of 170 A, defined as a single 8.3 ms half-sine waveform. This rating is validated per industry standards and supports robust transient suppression in DC bus and power supply applications without derating.
How does the thermal resistance of SMBG5362B/TR13 compare between junction-to-lead and junction-to-ambient?
SMBG5362B/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W (on FR4 with recommended footprint). The 3.6× difference highlights that effective heat transfer relies on copper pour under the leads-not just ambient convection-so PCB layout must prioritize thermal vias and wide traces to the anode/cathode pads.
Is SMBG5362B/TR13 compatible with lead-free reflow processes?
Yes, SMBG5362B/TR13 features RoHS-compliant annealed matte-tin plating and is qualified for standard lead-free reflow profiles up to 260 °C for 10 seconds. Its gull-wing geometry ensures reliable wetting and self-alignment during reflow, and the UL94V-0 epoxy body withstands repeated thermal cycling without delamination.
