Product details
Overview
SMBG5353AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 16 V, ±10% tolerance (A suffix), and maximum Zener current IZM of 6.0 mA at TL < 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and operates across –65 °C to +150 °C junction temperature range. It serves as a precision voltage reference or overvoltage clamp in power supply feedback loops.
For engineers reviewing the SMBG5353AE3/TR13 datasheet, SMBG5353AE3/TR13 pinout, SMBG5353AE3/TR13 application, or SMBG5353AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), surge current rating (IZSM = 6.0 A), moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage regulator diode operating in reverse-biased breakdown mode. Its Zener voltage is specified at 16 V with test current IZT = 75 mA, dynamic impedance ZZT = 2.5 Ω, and knee impedance ZZK = 295 Ω at 1.0 mA.
It delivers stable regulation over wide current (IZ = 1.0 mA to IZM) and temperature (–65 °C to +150 °C) ranges, with low leakage (IR ≤ 1.0 µA at VR = 11.5 V) and high surge capability (non-repetitive 8.3 ms half-sine IZSM = 6.0 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±10% - defines regulated output voltage under 75 mA test current; actual range 14.4 V to 17.6 V. |
| Power Dissipation (PD) | 5.0 W @ TL < 25 °C - requires thermal management when mounted on FR4; derates linearly above 25 °C. |
| Dynamic Impedance (ZZT) | 2.5 Ω - low AC impedance ensures minimal voltage variation under small-signal ripple or load transients. |
| Max Reverse Current (IR) | ≤1.0 µA @ VR = 11.5 V - confirms tight leakage control below breakdown, critical for low-power bias networks. |
| Surge Current (IZSM) | 6.0 A (8.3 ms half-sine) - enables robust transient suppression without degradation in surge-prone inputs. |
| Junction Temp Range | –65 °C to +150 °C - supports operation in automotive under-hood, industrial motor drives, and outdoor power systems. |
| Moisture Sensitivity | Level 1 per J-STD-020B - no dry pack required; simplifies SMT handling and eliminates bake-out prior to reflow. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode; polarity must be observed-cathode (banded end) is positive during regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; establishes reference for Zener conduction path. |
| Cathode | Regulated output node | Banded terminal; connected to voltage node requiring stabilization; sinks current to maintain 16 V regulation. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5353B equivalence | Identical electrical specs and test methods to legacy through-hole 1N5353B-enables drop-in replacement in upgraded layouts. |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow wetting on standard SMT lines without tombstoning risk. |
| RoHS-compliant matte-tin plating | e3 suffix confirms lead-free finish meeting IPC-J-STD-006; compatible with Pb-free and mixed-technology assembly. |
| MSL Level 1 rating | Eliminates floor-life tracking and pre-reflow baking-reduces manufacturing overhead and avoids moisture-induced popcorning. |
| High IZSM / IZM ratio | 6.0 A surge vs. 6.0 mA DC max implies 1000× overload capacity-ideal for protecting downstream ICs from line surges. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Regulates error amplifier reference in isolated flyback converter feedback network. IC Role / Device Role / Timing Role: Zener diode provides stable 16 V reference for optocoupler LED drive and TL431 biasing. Use Value: Tight ±10% VZ tolerance and low ZZT ensure consistent loop gain and output voltage accuracy across line/load/temperature. |
Use Scenario: Clamps analog sensor output (e.g., 4–20 mA transmitter) against ESD or inductive kick. IC Role / Device Role / Timing Role: Two-terminal overvoltage protector placed at signal input stage before ADC front-end. Use Value: 6.0 A surge rating and MSL Level 1 allow direct placement on exposed I/O traces without additional protection circuitry. |
| Automotive Body Control Module | Telecom Line Interface Protection |

IC Role / Device Role / Timing Role: Shunt regulator maintaining clean local VDD for CAN transceivers and GPIO buffers. Use Value: –65 °C to +150 °C operation and 25 °C/W RθJL support thermal reliability in engine bay proximity mounting. |
Use Scenario: Protects DSL or POTS line interface ICs from lightning-induced surges on twisted-pair lines. IC Role / Device Role / Timing Role: Primary shunt clamp on differential pair, coordinated with gas discharge tube (GDT) upstream. Use Value: 6.0 A non-repetitive surge rating and low IR (<1 µA) preserve signal integrity while absorbing 10/700 µs transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5353BRLG | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IR specs; higher RθJA (125 °C/W) limits power handling in confined spaces. | Requires through-hole assembly and board real estate; unsuitable for high-density SMT designs. | Select when legacy through-hole compatibility or manual repairability is prioritized over board space and automated assembly. |
| SMBJ5353B | DO-214AA (J-bend) package; same electrical specs but different footprint; RθJL = 30 °C/W (vs. 25 °C/W); slightly lower IZSM (5.8 A). | Compatible with existing SMBJ land patterns; less effective thermal transfer than SMBG's gull-wing leads. | Choose when migrating from SMBJ footprint or when gull-wing inspection is not required and cost is constrained. |
Compared with SMBG5353AE3/TR13, 1N5353BRLG trades SMT efficiency for mechanical serviceability, while SMBJ5353B offers footprint flexibility at minor thermal and surge performance cost-both require layout revision but preserve regulation behavior.

FAQ
What is the Zener voltage tolerance for SMBG5353AE3/TR13?
The "A" suffix in SMBG5353AE3/TR13 specifies ±10% Zener voltage tolerance, meaning its breakdown voltage falls between 14.4 V and 17.6 V at 75 mA test current and 25 °C. This tolerance is verified per JEDEC test conditions and applies across the full operating temperature range of –65 °C to +150 °C.
Is SMBG5353AE3/TR13 RoHS compliant?
Yes, SMBG5353AE3/TR13 is RoHS compliant, as confirmed by the "e3" suffix in its part number. It features annealed matte-tin plating per MIL-STD-750, method 2026, and meets all substance restrictions defined in Directive 2011/65/EU without exemptions.
What is the maximum surge current rating for SMBG5353AE3/TR13?
SMBG5353AE3/TR13 has a non-repetitive peak surge current (IZSM) rating of 6.0 A for an 8.3 ms half-sine waveform. This value is measured under standardized conditions and supports robust transient suppression in power input stages and signal line protection circuits.
Does SMBG5353AE3/TR13 require dry packing before reflow soldering?
No, SMBG5353AE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This eliminates process steps and reduces manufacturing risk.
How does the thermal resistance of SMBG5353AE3/TR13 compare to axial-leaded equivalents?
SMBG5353AE3/TR13 has RθJL = 25 °C/W, significantly lower than axial-leaded 1N5353B (RθJA ≈ 125 °C/W). This allows SMBG5353AE3/TR13 to dissipate 5 W more efficiently when lead-attached heat sinking is used-critical for compact, thermally constrained PCB layouts.
