Product details
Overview
SMBG5341CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 6.2 V, ±2% tolerance (C suffix), and maximum Zener current of 765 mA at 25 °C. It uses DO-215AA gull-wing package, supports visible solder joints, and is rated for junction temperatures from –65 °C to +150 °C. It serves as a precision voltage reference or overvoltage clamp in power supply feedback loops.
For engineers reviewing the SMBG5341CE3/TR13 datasheet, SMBG5341CE3/TR13 pinout, SMBG5341CE3/TR13 application, or SMBG5341CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at test current, surge current rating, thermal resistance junction-to-lead, and RoHS-compliant matte-tin plating compatibility with lead-free reflow.
Technical Context
This device operates in reverse-biased breakdown mode with specified Zener voltage measured at IZT = 200 mA and TL = 30 °C. Its dynamic impedance is 1.0 Ω at IZT, and knee impedance is 200 Ω at 1.0 mA, indicating stable regulation across wide current ranges.
The SMBG5341CE3/TR13 exhibits low leakage: maximum reverse current is 1.0 µA at VR = 3.0 V. It withstands non-repetitive 8.3 ms half-sine surge currents up to 12.4 A and maintains moisture sensitivity level 1 per J-STD-020B-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±2% at IZT = 200 mA - ensures tight regulation in feedback networks requiring stable reference under load variation. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - enables high-current clamping without external heatsink when lead temperature is controlled. |
| Dynamic Impedance (ZZT) | 1.0 Ω at IZT = 200 mA - minimizes output voltage deviation during transient current changes in regulator circuits. |
| Max Surge Current (IZSM) | 12.4 A (8.3 ms half-sine) - provides robust protection against short-duration line transients in DC power rails. |
| Junction-to-Lead Thermal Resistance | 25 °C/W - allows direct thermal path to PCB copper, supporting reliable operation at elevated ambient temperatures with proper layout. |
| Reverse Leakage (IR) | 1.0 µA at VR = 3.0 V - ensures minimal quiescent current draw in battery-powered or low-power standby circuits. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end must be held positive relative to anode during operation. Terminals are tin-plated for RoHS compliance and solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential node in Zener regulation | Must be routed to ground or return path; determines polarity of clamping action in overvoltage protection. |
| Cathode | Current exit terminal in forward bias; connected to higher-potential node in Zener regulation | Banded end; connects to regulated rail or feedback node; defines direction of voltage reference and clamping. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5341B Equivalent | Identical electrical characteristics and testing - enables drop-in replacement in legacy designs qualified to 1N5341B. |
| Gull-Wing Lead Geometry | Visible solder joints on DO-215AA footprint - supports automated optical inspection (AOI) and improves process yield in high-volume SMT lines. |
| Moisture Sensitivity Level 1 | No dry pack required per J-STD-020B - eliminates baking step before reflow, reducing manufacturing cost and handling risk. |
| RoHS Compliant Matte-Tin Plating | e3 suffix indicates annealed matte-tin finish - compatible with Pb-free reflow profiles up to 260 °C for 10 s without degradation. |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp for 5 V Rail |
|---|---|
Use Scenario: Used in TL431-based shunt regulator feedback network to set precise 5 V output in isolated flyback converters. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference that biases TL431's reference input, enabling accurate output voltage regulation. Use Value: ±2% VZ tolerance and 1.0 Ω ZZT ensure <±1% output drift over line/load/temperature, meeting industrial-grade PSU specs. | Use Scenario: Placed across 5 V logic rail to clamp transients exceeding 6.2 V during hot-swap or ESD events. IC Role / Device Role / Timing Role: Acts as passive crowbar element, conducting excess energy to ground when rail exceeds Zener breakdown threshold. Use Value: 12.4 A surge rating and 5 W steady-state dissipation protect downstream 5 V ICs without requiring active circuitry or response delay. |
| Industrial Sensor Signal Conditioning | Programmable Logic Controller Input Protection |
Use Scenario: Mounted at analog front-end of 4–20 mA transmitter to limit input voltage to ADC driver stage. IC Role / Device Role / Timing Role: Clamps common-mode voltage excursions beyond 6.2 V, preventing saturation or damage to op-amp input stages. Use Value: Low 1.0 µA leakage at 3.0 V ensures negligible loading on high-impedance sensor bridges or thermocouple circuits. | Use Scenario: Integrated into digital input module to suppress induced surges on 24 V DC field wiring entering PLC chassis. IC Role / Device Role / Timing Role: Functions as first-line transient voltage suppressor ahead of optocoupler or Schmitt trigger input conditioning. Use Value: DO-215AA gull-wing geometry allows compact placement near connector, minimizing loop inductance and improving high-frequency surge suppression. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same VZ = 6.2 V, ±5% tolerance, 1.0 Ω ZZT, but Sn/Pb plating and non-RoHS compliant | Not suitable for lead-free assembly; requires different reflow profile and may not meet modern environmental compliance mandates | Select only for legacy repair or non-RoHS production environments where e3 compliance is not required. |
| SMBJ5341B | Same VZ = 6.2 V, ±5%, but in DO-214AA (J-bend) package with RθJA = 90 °C/W vs. 25 °C/W for SMBG | Lower thermal performance limits continuous power handling on standard FR4; unsuitable for high-duty-cycle clamping | Choose only when board space constraints favor J-bend footprint or when thermal demands are below 1.38 W at TA = 25 °C. |
Compared with 1N5341B and SMBJ5341B, SMBG5341CE3/TR13 delivers tighter ±2% voltage tolerance, RoHS-compliant matte-tin plating, and superior thermal resistance (25 °C/W) - making it optimal for new designs requiring precision regulation, lead-free compliance, and efficient heat transfer via leads.

FAQ
What is the Zener voltage tolerance of SMBG5341CE3/TR13?
The SMBG5341CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its breakdown voltage is guaranteed between 6.076 V and 6.324 V when tested at IZT = 200 mA and TL = 30 °C. This tighter tolerance supports precision regulation tasks where 1N5341B's ±5% would introduce unacceptable error in SMBG5341CE3/TR13-based feedback networks.
Does SMBG5341CE3/TR13 require dry packing before reflow soldering?
No, SMBG5341CE3/TR13 does not require dry packing prior to reflow soldering. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. This eliminates pre-reflow desiccation steps and reduces handling risk - a key advantage of SMBG5341CE3/TR13 in high-throughput SMT lines.
What is the maximum surge current rating for SMBG5341CE3/TR13?
The SMBG5341CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 12.4 A, defined as the maximum value of an 8.3 ms half-sine waveform. This rating is confirmed in the Electrical Characteristics table on page 3 of the Microsemi datasheet T4-LDS-0246-1. It enables SMBG5341CE3/TR13 to absorb common power-line transients without failure.
How does the thermal resistance of SMBG5341CE3/TR13 compare to other 5 W Zeners?
SMBG5341CE3/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, significantly lower than its junction-to-ambient rating of 90 °C/W. This reflects its optimized DO-215AA gull-wing package, which conducts heat efficiently through the leads to PCB copper. In contrast, SMBJ5341B in DO-214AA offers only RθJA = 90 °C/W with no RθJL spec - confirming SMBG5341CE3/TR13's superior thermal path for sustained power dissipation.
Is SMBG5341CE3/TR13 compatible with lead-free reflow processes?
Yes, SMBG5341CE3/TR13 is fully compatible with lead-free reflow processes. Its "e3" suffix confirms RoHS-compliant annealed matte-tin plating, qualified for soldering at 260 °C for 10 seconds per MIL-STD-750 Method 2026. This makes SMBG5341CE3/TR13 suitable for modern Pb-free assembly lines without compromising solder joint integrity or long-term reliability.
