Product details
Overview
SMBG5356AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 19 V, ±10% tolerance (A suffix), rated test current of 65 mA, maximum dynamic impedance of 3.0 Ω at IZT, and maximum regulator current of 5.3 A - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5356AE3/TR13 datasheet, SMBG5356AE3/TR13 pinout, SMBG5356AE3/TR13 application, or SMBG5356AE3/TR13 equivalent, this page delivers verified electrical parameters, DO-215AA gull-wing package details, JEDEC 1N5356A compatibility, thermal derating behavior, and RoHS-compliant matte-tin plating confirmation - all critical for industrial power rail design and BOM validation.
Technical Context
This device operates as a silicon planar Zener diode in reverse-biased breakdown mode, delivering stable reference voltage across wide current (1–5.3 A) and temperature (−65 °C to +150 °C) ranges. Its low dynamic impedance (3.0 Ω) ensures minimal voltage variation under load transients.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it features 25 °C/W junction-to-lead thermal resistance and 90 °C/W junction-to-ambient rating - enabling 5 W dissipation only when lead temperature remains ≤25 °C, or 1.38 W at ambient 25 °C with standard layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19 V ±10% - defines regulated output voltage at 65 mA test current; high-end tolerance limit is 20.9 V for IZM calculation. |
| Power Dissipation (PD) | 5.0 W @ TL ≤ 25 °C - requires heatsinking via PCB copper; drops to 1.38 W at TA = 25 °C without forced cooling. |
| Dynamic Impedance (ZZT) | 3.0 Ω max @ 65 mA - ensures <30 mV voltage shift per 10 mA load change near regulation point. |
| Max Regulator Current (IZM) | 5.3 A - derived from PD/VZM; enables robust surge handling up to 5.3 A DC without degradation. |
| Reverse Leakage (IR) | 0.5 µA max @ 13.7 V - guarantees negligible standby current in high-impedance bias networks. |
| Junction Temp Range | −65 °C to +150 °C - supports operation in automotive under-hood and industrial motor drive environments. |
| Moisture Sensitivity | Level 1 per J-STD-020B - no dry pack required; compatible with standard reflow profiles including 260 °C peak. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; void-free UL94V-0 epoxy body; matte-tin (e3) RoHS-compliant plating; 0.1 g weight; visible solder joints enable optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node; carries forward current up to 1.0 A (VF = 1.2 V). |
| Cathode (banded end) | Zener breakdown terminal | Connected to higher-potential node; regulates voltage when reverse biased above 19 V. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5356A equivalence | Identical electrical specs and test methods - allows drop-in replacement in legacy designs using axial 1N5356A. |
| Gull-wing lead form | Enables visual solder joint inspection and reliable reflow yield on automated SMT lines. |
| Level 1 moisture sensitivity | Eliminates baking requirement before assembly - reduces manufacturing cost and cycle time. |
| High surge current rating | IZSM = 5.3 A (8.3 ms half-sine) - protects downstream circuitry from transient overvoltage events. |
| Stable VZ vs. current | Low ZZT (3.0 Ω) and flat regulation curve - maintains accuracy across 10:1 current range (6.5–65 mA). |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for Microcontroller I/O |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback converter feedback path via optocoupler. IC Role / Device Role / Timing Role: Precision voltage reference diode providing stable 19 V threshold to error amplifier input. Use Value: Maintains ±1% output regulation across line/load/temperature with minimal drift due to low ZZT and tight VZ tolerance. |
Use Scenario: Clamps 3.3 V or 5 V digital I/O pins against ESD or inductive kickback. IC Role / Device Role / Timing Role: Fast-acting shunt protector absorbing transient energy before IC damage occurs. Use Value: Withstands 5.3 A surge (8.3 ms) and exhibits only 0.5 µA leakage at 13.7 V - preserving signal integrity during normal operation. |
| Industrial Sensor Signal Conditioning | Programmable Reference Voltage Generator |
Use Scenario: Provides stable bias voltage for analog front-end op-amps in 4–20 mA transmitter modules. IC Role / Device Role / Timing Role: Low-drift Zener reference source ensuring consistent gain and offset calibration. Use Value: Junction temp range (−65 °C to +150 °C) and low TC support operation in uncontrolled enclosures without active thermal management. |
Use Scenario: Sets precise threshold in adjustable voltage monitor or window comparator circuit. IC Role / Device Role / Timing Role: Fixed 19 V reference node enabling accurate trip-point selection via resistor divider. Use Value: ±10% VZ tolerance and 3.0 Ω ZZT ensure predictable hysteresis and minimal threshold shift under varying load conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5356A | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM; non-RoHS (Sn/Pb) plating. | Requires through-hole assembly; unsuitable for high-density SMT layouts. | Select when retrofitting legacy through-hole boards or where manual repair accessibility is prioritized. |
| SMBJ5356B | DO-214AA J-bend package; same VZ and IZT, but ±5% tolerance (B suffix); ZZT = 3.0 Ω; RoHS compliant. | Higher voltage precision at cost of tighter tolerance; J-bend leads less inspectable than gull-wing. | Select when ±5% regulation accuracy is required and DO-214AA footprint is already standardized in design. |
Compared with SMBG5356AE3/TR13, 1N5356A offers identical regulation performance but mandates through-hole assembly, while SMBJ5356B provides tighter ±5% tolerance in a different surface-mount package - making SMBG5356AE3/TR13 optimal for new RoHS-compliant SMT designs needing ±10% tolerance and gull-wing manufacturability.

FAQ
What is the Zener voltage tolerance for SMBG5356AE3/TR13?
The 'A' suffix in SMBG5356AE3/TR13 specifies ±10% Zener voltage tolerance, meaning the actual VZ falls between 17.1 V and 20.9 V at 65 mA test current and 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet, and applies directly to the SMBG5356AE3/TR13 device.
Is SMBG5356AE3/TR13 RoHS compliant?
Yes, SMBG5356AE3/TR13 is RoHS compliant, as indicated by the 'e3' suffix in its part number. The device uses annealed matte-tin plating per MIL-STD-750 method 2026 and meets EU Directive 2011/65/EU requirements - verified in the Features and Mechanical sections of the official Microsemi datasheet.
What is the maximum continuous Zener current for SMBG5356AE3/TR13?
The maximum regulator current (IZM) for SMBG5356AE3/TR13 is 5.3 A, calculated as PD/VZM = 5.0 W / 20.9 V. This value assumes junction temperature remains within limits and is validated in the Electrical Characteristics table on page 3 of the datasheet.
Does SMBG5356AE3/TR13 require dry packing before reflow soldering?
No, SMBG5356AE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored and processed without dry packing or baking. This is explicitly stated in the Applications/Benefits section and confirmed in the Mechanical and Packaging section of the datasheet.
How does SMBG5356AE3/TR13 compare to the axial 1N5356A?
SMBG5356AE3/TR13 is the surface-mount DO-215AA gull-wing equivalent of the axial-leaded 1N5356A, with identical Zener voltage, test current, dynamic impedance, and power rating. Both share the same electrical characteristics and testing per JEDEC standards - making SMBG5356AE3/TR13 a direct functional replacement in SMT designs.
