Product details
Overview
SMBG5350CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 13 V, ±2% tolerance (C suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges and withstands high surge stresses in power supply and protection circuits.
For engineers reviewing the SMBG5350CE3/TR13 datasheet, SMBG5350CE3/TR13 pinout, SMBG5350CE3/TR13 application, or SMBG5350CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy (±2%), maximum regulator current (IZM = 7.0 mA at 13 V), thermal resistance (RθJL = 25 °C/W), and surge current rating (IZSM = 7.0 A for 8.3 ms half-sine).
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power rails. Its low dynamic impedance (ZZT = 2.5 Ω at IZT = 100 mA) ensures stable regulation under varying load conditions, while its Level 1 moisture sensitivity rating eliminates dry-pack requirements.
The SMBG5350CE3/TR13 uses a void-free thermosetting epoxy case (UL94V-0), gull-wing leads solderable per MIL-STD-750 Method 2026, and cathode polarity marked by a band. It delivers 5.0 W at TL < 25 °C or 1.38 W at TA = 25 °C on FR4 with recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±2% at IZT = 100 mA - defines precise clamping threshold for 12 V rail protection |
| Max Regulator Current (IZM) | 7.0 mA - maximum continuous DC current before exceeding 5 W power limit at VZ |
| Dynamic Impedance (ZZT) | 2.5 Ω - low AC impedance ensures minimal voltage deviation under ripple or transient load changes |
| Surge Current (IZSM) | 7.0 A (8.3 ms half-sine) - supports transient overvoltage suppression without failure |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer to PCB copper, critical for sustained 5 W operation |
| Reverse Leakage (IR) | 1.0 µA at VR = 10.1 V - negligible standby current in high-impedance bias networks |
| Junction Temperature Range | –65 to +150 °C - suitable for automotive under-hood and industrial control environments |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by a band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential node during Zener operation; carries full regulator current |
| Cathode (banded end) | High-side connection point | Connected to protected rail or reference node; reverse-biased to maintain regulated voltage drop |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5350B equivalent | Fully compatible with legacy 1N5350B designs-identical electrical specs and test methods |
| Level 1 moisture sensitivity | No dry-pack required; simplifies handling, storage, and SMT assembly logistics |
| High surge capability | 7.0 A non-repetitive surge rating enables robust ESD and lightning-induced transient suppression |
| Low dynamic impedance | 2.5 Ω at 100 mA ensures tight voltage regulation even with ±10% load variation |
| RoHS-compliant finish (e3) | Matte-tin plating meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5350B | Same 13 V ±2%, 5 W rating, but axial T-18 package; higher RθJA (125 °C/W vs. 90 °C/W); non-RoHS leaded finish | Requires through-hole assembly; unsuitable for high-density SMT layouts or RoHS-compliant production | Select when legacy through-hole design or cost-sensitive non-RoHS production is required |
| SMBJ5350B | Identical electrical specs and DO-214AA J-bend package; same 13 V ±2%, 5 W, RoHS-compliant; different footprint and lead form | Compatible with automated pick-and-place but requires revised land pattern; no gull-wing visual inspection advantage | Select when existing DO-214AA footprint is standardized and gull-wing inspection is not required |
Compared with SMBG5350CE3/TR13, 1N5350B trades SMT compatibility and RoHS compliance for through-hole simplicity, while SMBJ5350B retains SMT benefits but sacrifices gull-wing solder joint visibility and thermal performance (RθJL = 30 °C/W vs. 25 °C/W).

FAQ
What is the Zener voltage tolerance of SMBG5350CE3/TR13?
The SMBG5350CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its breakdown voltage is guaranteed between 12.74 V and 13.26 V at the specified test current of 100 mA and junction temperature of 25 °C, as confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0246-1 datasheet.
Does SMBG5350CE3/TR13 require dry packing before reflow soldering?
No, SMBG5350CE3/TR13 does not require dry packing. It carries a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions (≤30 °C / 60% RH) without baking prior to reflow. This is explicitly stated in the Applications/Benefits section and Maximum Ratings table.
What is the maximum continuous power dissipation for SMBG5350CE3/TR13 on a standard FR4 board?
When mounted on an FR4 PCB with 1 oz copper and the recommended footprint, SMBG5350CE3/TR13 delivers 1.38 W at ambient temperature (TA = 25 °C), as specified in Note 2 of the Maximum Ratings table. At lead temperature <25 °C (e.g., with heatsinking), it achieves its full 5.0 W rating.
Is SMBG5350CE3/TR13 compatible with lead-free reflow profiles?
Yes, SMBG5350CE3/TR13 supports lead-free reflow with a peak solder temperature of 260 °C for 10 seconds, as documented in the Maximum Ratings table. Its RoHS-compliant matte-tin (e3) plating is qualified for standard JEDEC J-STD-020 profiles, including ramp rates and time-above-liquidus specifications.
How does the gull-wing lead form of SMBG5350CE3/TR13 benefit manufacturing inspection?
The gull-wing lead configuration of SMBG5350CE3/TR13 enables visible solder joints after reflow, facilitating automated optical inspection (AOI) and manual visual verification. This contrasts with J-bend packages like SMBJ5350B, where solder fillets are hidden beneath the body-reducing defect detection rates in high-reliability production lines.
