Product details
Overview
SMBG5340AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 6.0 V, ±10% tolerance (A suffix), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 12.7 A (8.3 ms half-sine), and operates from –65 °C to +150 °C junction temperature - used in power supply overvoltage clamping and reference circuits.
For engineers reviewing the SMBG5340AE3/TR13 datasheet, SMBG5340AE3/TR13 pinout, SMBG5340AE3/TR13 application, or SMBG5340AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), maximum regulator current (IZM = 790 mA), surge capability (IZSM = 12.7 A), and RoHS-compliant matte-tin plating (e3 suffix).
Technical Context
This device functions as a precision voltage reference and transient clamp by operating in reverse-biased breakdown mode. Its dynamic impedance is 1.0 Ω at IZT = 200 mA, and it maintains stable regulation with minimal voltage drift versus current due to low ZZT and high IZM.
Designed for surface-mount assembly on FR4 PCBs with recommended footprint, it achieves RθJA = 90 °C/W and RθJL = 25 °C/W. The cathode band identifies polarity, and moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±10% - defines clamping threshold under 200 mA test current; usable for 5.4–6.6 V regulation window. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management when mounted on PCB; derates linearly above 25 °C. |
| Max Regulator Current (IZM) | 790 mA - maximum continuous DC current before exceeding 5 W rating at upper VZ limit (6.6 V). |
| Surge Current (IZSM) | 12.7 A (8.3 ms half-sine) - withstands short-duration transients without failure in protection circuits. |
| Dynamic Impedance (ZZT) | 1.0 Ω @ 200 mA - ensures tight voltage regulation under varying load conditions. |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer to PCB lead, critical for sustained 5 W operation. |
| Reverse Leakage (IR) | 1.0 µA @ 4.9 V - guarantees low standby power loss in high-impedance bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with two terminals: anode and cathode. Cathode identified by molded band; device operated with banded end positive relative to anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown terminal | Connected to higher potential node during regulation; carries full Zener current in clamping mode. |
| Anode | Reference terminal | Connected to circuit ground or lower-potential rail; completes reverse-bias path for Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5340B equivalent | Identical electrical specs and testing - enables drop-in replacement in legacy designs using axial 1N5340B. |
| RoHS-compliant matte-tin plating (e3) | Meets environmental compliance without sacrificing solderability or reliability per MIL-STD-750 Method 2026. |
| Gull-wing leads (DO-215AA) | Enables visual solder-joint inspection and high-density placement on compact PCBs. |
| Moisture Sensitivity Level 1 | No dry-pack or baking required before reflow - reduces manufacturing overhead and handling risk. |
| High surge current rating | 12.7 A non-repetitive peak withstand - suitable for automotive load-dump and industrial transient suppression. |
Applications
| Power Supply Overvoltage Clamp | DC Reference Voltage Generator |
|---|---|
Use Scenario: Protects downstream regulators and ICs from input voltage spikes in 5–12 V DC power rails. IC Role / Device Role / Timing Role: Zener diode acts as shunt regulator, conducting excess current when input exceeds 6.6 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Axial-leaded T-18 package; identical VZ, IZM, and ZZT; no RoHS e3 marking. | Requires through-hole assembly; unsuitable for high-density SMT layouts. | Select when legacy through-hole design or manual prototyping is required. |
| SMBJ5340B | DO-214AA J-bend package; same VZ and power rating; RθJA = 100 °C/W (higher than SMBG's 90 °C/W). | Lower thermal performance on FR4; less effective for sustained 5 W operation without heatsinking. | Select only if DO-214AA footprint compatibility is mandatory and thermal margin exists. |
Compared with SMBG5340AE3/TR13, 1N5340B offers identical regulation but lacks SMT compatibility and RoHS compliance, while SMBJ5340B sacrifices thermal efficiency for alternate leadform - SMBG5340AE3/TR13 delivers optimal balance of SMT manufacturability, thermal performance, and environmental compliance.

FAQ
What is the Zener voltage tolerance for SMBG5340AE3/TR13?
The SMBG5340AE3/TR13 has a ±10% Zener voltage tolerance (denoted by the "A" suffix), resulting in a guaranteed breakdown voltage range of 5.4 V to 6.6 V at 200 mA test current. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet. The SMBG5340AE3/TR13 maintains this specification across its full operating temperature range of –65 °C to +150 °C.
Is SMBG5340AE3/TR13 RoHS compliant?
Yes, SMBG5340AE3/TR13 is RoHS compliant, indicated by the "e3" suffix in its part number. It uses annealed matte-tin plating per MIL-STD-750 Method 2026 and meets EU Directive 2011/65/EU requirements. The device is also rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, eliminating the need for dry packing prior to reflow soldering - a key requirement for SMBG5340AE3/TR13 in modern eco-conscious manufacturing.
What is the maximum surge current rating for SMBG5340AE3/TR13?
The SMBG5340AE3/TR13 has a maximum non-repetitive surge current (IZSM) of 12.7 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table. This rating enables the SMBG5340AE3/TR13 to absorb transient energy in automotive load-dump and industrial inductive switching events without degradation, provided the surge interval allows sufficient thermal recovery between events.
How does SMBG5340AE3/TR13 compare thermally to other 5 W Zeners in DO-214AA?
SMBG5340AE3/TR13 achieves RθJL = 25 °C/W and RθJA = 90 °C/W on FR4 with recommended footprint - superior to DO-214AA alternatives like SMBJ5340B (RθJA = 100 °C/W). This 10 °C/W improvement means SMBG5340AE3/TR13 runs cooler at full 5 W dissipation, enhancing long-term reliability in thermally constrained applications such as enclosed power supplies.
Can SMBG5340AE3/TR13 replace 1N5340B in existing designs?
Yes, SMBG5340AE3/TR13 is electrically equivalent to 1N5340B per Microsemi documentation, sharing identical VZ, IZM, ZZT, and surge ratings. However, the SMBG5340AE3/TR13 uses DO-215AA gull-wing packaging versus T-18 axial leads - direct replacement requires PCB redesign. For drop-in use, verify mechanical fit and thermal pad layout; SMBG5340AE3/TR13 offers improved manufacturability and RoHS compliance over 1N5340B.
