Product details
Overview
SMBG5352AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 15 V, ±10% tolerance (A-suffix), and DO-215AA gull-wing package. It delivers stable voltage regulation across wide current (75 mA IZT) and temperature (–65 °C to +150 °C) ranges, and is used in power supply overvoltage clamping and reference circuits.
For engineers reviewing the SMBG5352AE3/TR13 datasheet, SMBG5352AE3/TR13 pinout, SMBG5352AE3/TR13 application, or SMBG5352AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (6.3 A IZSM), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with dynamic impedance of 2.5 Ω at 75 mA test current and knee impedance of 315 Ω at 1 mA. Its low RθJL enables efficient heat transfer to the PCB lead frame under sustained 5 W dissipation at TL < 25 °C.
The DO-215AA gull-wing package ensures visible solder joints and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Cathode polarity is marked by a band; operation requires cathode-positive bias relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±10% at 75 mA - defines regulated output level with worst-case range 13.5–16.5 V |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - maximum steady-state power handling with adequate lead heatsinking |
| Dynamic Impedance (ZZT) | 2.5 Ω @ 75 mA - low AC impedance ensures minimal voltage variation under load transients |
| Max Surge Current (IZSM) | 6.3 A (8.3 ms half-sine) - supports transient overvoltage suppression without failure |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct thermal path from junction to PCB lead, critical for reliability at full power |
| Reverse Leakage (IR) | 1.0 µA @ 10.8 V - confirms tight regulation near knee voltage with negligible standby loss |
| Junction Temp Range | –65 °C to +150 °C - validated operation across industrial and automotive ambient extremes |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by molded band; terminals are anode (unbanded end) and cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground node in Zener clamp configuration | Connected to lower-potential side of protected circuit; establishes reference point for clamping threshold |
| Cathode | Current exit terminal in forward bias; high-side connection in Zener regulator mode | Banded terminal tied to input rail or voltage source; sets regulated output at cathode potential |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5352B equivalent | Identical electrical specs and test methods - enables drop-in replacement in legacy designs |
| RoHS-compliant matte-tin plating | e3 suffix confirms annealed tin finish meeting MIL-STD-750 Method 2026 solderability |
| Level 1 moisture sensitivity | No dry pack or bake required before reflow - reduces manufacturing overhead and floor-life constraints |
| Gull-wing lead form | Visible solder fillets per IPC-A-610 - enables automated optical inspection (AOI) of joint integrity |
| High IZM at 75 mA | Supports robust regulation under sustained load without thermal runaway when mounted per recommended footprint |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5352B | Same 15 V ±10%, 5 W, DO-41 axial package; higher RθJA (120 °C/W vs. 90 °C/W) | Requires through-hole mounting and larger board area; less suitable for high-density SMT layouts | Select 1N5352B only if legacy through-hole assembly or manual repair is required. |
| SMBJ5352B | Same electrical specs but DO-214AA J-bend package; RθJL not specified; no gull-wing visual inspection capability | Compatible with standard SMT pick-and-place but lacks solder-fillet visibility for AOI validation | Choose SMBJ5352B when footprint compatibility with existing DO-214AA designs is mandatory. |
Compared with SMBG5352AE3/TR13, 1N5352B trades SMT density and thermal performance for through-hole serviceability, while SMBJ5352B retains surface-mount compatibility but sacrifices gull-wing inspection advantages and published thermal metrics.

FAQ
What is the Zener voltage tolerance of SMBG5352AE3/TR13?
The SMBG5352AE3/TR13 has a Zener voltage tolerance of ±10%, denoted by the "A" suffix in its part number. This means its measured VZ falls between 13.5 V and 16.5 V at 75 mA test current and 25 °C. The tolerance is verified per JEDEC test methods and applies across the full operating temperature range of –65 °C to +150 °C.
Does SMBG5352AE3/TR13 require dry packing before reflow soldering?
No, SMBG5352AE3/TR13 does not require dry packing. 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 pre-reflow bake cycles and simplifies SMT line logistics compared to MSL 2a or higher devices.
What is the maximum surge current rating for SMBG5352AE3/TR13?
The SMBG5352AE3/TR13 has a maximum non-repetitive peak surge current (IZSM) of 6.3 A, specified for an 8.3 ms half-sine waveform. This rating is validated per Microsemi's test methodology and supports transient suppression in automotive load-dump and industrial surge environments without parametric shift or failure.
How does the DO-215AA package of SMBG5352AE3/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5352AE3/TR13 uses gull-wing leads enabling visible solder fillets for AOI, whereas DO-214AA (used in SMBJ5352B) employs J-bend leads with hidden solder joints. DO-215AA also specifies RθJL = 25 °C/W, a thermal metric not published for DO-214AA variants of this series.
Is SMBG5352AE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5352AE3/TR13 features RoHS-compliant matte-tin plating (e3 suffix) qualified for lead-free reflow up to 260 °C for 10 seconds. Its thermosetting epoxy body meets UL94V-0 flammability rating, and the device passes solderability testing per MIL-STD-750 Method 2026 under standard Pb-free thermal profiles.
