Product details
Overview
SMBG5362CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 28 V, ±2% tolerance (C suffix), DO-215AA gull-wing package, 50 mA test current (IZT), and 6.0 Ω dynamic impedance (ZZT) at IZT - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5362CE3/TR13 datasheet, SMBG5362CE3/TR13 pinout, SMBG5362CE3/TR13 application, or SMBG5362CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (130 A), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable voltage across wide current (50 mA IZT to 3.9 A IZM) and temperature (-65 to +150 °C) ranges. Its low dynamic impedance (6.0 Ω) ensures minimal voltage variation under load transients.
The DO-215AA gull-wing package provides visible solder joints and 25 °C/W junction-to-lead thermal resistance, enabling reliable 5 W dissipation when lead-temperature (TL) is held ≤25 °C - critical for high-reliability industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±2% at 50 mA - enables precise reference in feedback networks requiring tight regulation. |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - supports continuous operation in thermally managed PCB layouts. |
| Dynamic Impedance (ZZT) | 6.0 Ω at 50 mA - limits output voltage shift to <300 mV under ±100 mA load step. |
| Max Regulator Current (IZM) | 3.9 A - defines absolute DC current limit before thermal runaway at rated power. |
| Surge Current (IZSM) | 130 A (8.3 ms half-sine) - withstands transient overvoltages per IEC 61000-4-5 Level 4. |
| Junction Temperature Range | -65 to +150 °C - suitable for automotive under-hood and industrial control environments. |
| Thermal Resistance (RθJL) | 25 °C/W - allows direct thermal path to copper pour or heatsink via leads for stable long-term bias. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed - cathode biased positive relative to anode during regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return; establishes reference potential for Zener conduction. |
| Cathode | Regulated output node | Biased positive relative to anode; delivers stable 28 V output when reverse current ≥50 mA. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow (260 °C, 10 s) without tin whisker risk or solder joint degradation. |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling, storage, and SMT line integration. |
| Gull-wing lead form | Provides visual solder joint inspection and mechanical strain relief on FR4 boards. |
| Non-ESD-sensitive design | Qualified to MIL-STD-750 Method 1020 - eliminates need for ESD handling controls in production. |
| High surge current rating | 130 A non-repetitive peak withstand - protects downstream circuitry from lightning-induced transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362BRLG | Same 28 V ±5%, DO-204AL axial package, higher RθJA (125 °C/W), no RoHS e3 marking. | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs. | Select only if legacy through-hole compatibility or cost sensitivity outweighs SMT efficiency and RoHS compliance. |
| SMBJ5362B | Identical electrical specs, same DO-214AA J-bend package (not gull-wing), 30 °C/W RθJL vs. 25 °C/W. | Compatible footprint but different lead geometry; requires requalification of solder joint reliability per IPC-A-610. | Prefer SMBG5362CE3/TR13 for new designs needing optimal thermal performance and visual solder inspection. |
Compared with 1N5362BRLG and SMBJ5362B, SMBG5362CE3/TR13 delivers superior thermal management (25 °C/W RθJL), RoHS compliance, and gull-wing manufacturability - making it the preferred choice for high-reliability SMT power regulation where lead-temperature control is critical.

FAQ
What is the Zener voltage tolerance of SMBG5362CE3/TR13?
The "C" suffix in SMBG5362CE3/TR13 specifies a ±2% Zener voltage tolerance at 50 mA test current, meaning the actual VZ falls between 27.44 V and 28.56 V under standard test conditions (TL = 25 °C). This tighter tolerance supports precision regulation where ±5% devices would introduce unacceptable output variation.
Can SMBG5362CE3/TR13 be used in lead-free reflow processes?
Yes - SMBG5362CE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) qualified for lead-free reflow up to 260 °C for 10 seconds per JEDEC J-STD-020. Its DO-215AA gull-wing leads accommodate standard SAC305 profile without solder joint cracking or dewetting.
What is the maximum continuous current SMBG5362CE3/TR13 can handle?
SMBG5362CE3/TR13 has a maximum regulator current (IZM) of 3.9 A when lead temperature (TL) is maintained at or below 25 °C. At higher TL, derating applies per the power derating curve - e.g., at TL = 75 °C, IZM drops to ~2.6 A to sustain 5 W safe operating area.
How does the DO-215AA package differ from DO-214AA for SMBG5362CE3/TR13?
DO-215AA uses gull-wing leads for visible solder joints and lower thermal resistance (25 °C/W RθJL), while DO-214AA (used in SMBJ5362B) employs J-bend leads with higher RθJL (30 °C/W). The gull-wing form also improves mechanical stability on thin PCBs and simplifies AOI inspection.
Is SMBG5362CE3/TR13 suitable for surge protection per IEC 61000-4-5?
Yes - SMBG5362CE3/TR13 is rated for 130 A non-repetitive surge current (IZSM) with 8.3 ms half-sine waveform, meeting IEC 61000-4-5 Level 4 requirements. Its low dynamic impedance (6.0 Ω) ensures clamping voltage stays within safe margins for 30 V-rated downstream components.
