Product details
Overview
SMBG5354C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 17 V, ±2% tolerance (C suffix), and maximum Zener current IZM of 5.8 mA at TL < 25 °C. It uses DO-215AA gull-wing package, delivers low dynamic impedance (2.5 Ω at IZT = 70 mA), and is rated for junction temperatures from –65 °C to +150 °C. It serves as precision voltage reference and overvoltage clamp in DC power rails.
For engineers reviewing the SMBG5354C/TR13 datasheet, SMBG5354C/TR13 pinout, SMBG5354C/TR13 application, or SMBG5354C/TR13 equivalent, key selection criteria include its 17 V regulation point, ±2% tolerance, 5 W power rating under lead-temperature-limited conditions, DO-215AA thermal resistance (RθJL = 25 °C/W), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased Zener breakdown mode, maintaining stable voltage across wide current (IZK to IZM) and temperature ranges. Its low knee impedance (ZZK ≤ 2.5 Ω @ 1.0 mA) ensures minimal voltage drift near the regulation knee, supporting accurate low-current references.
Designed for surface-mount high-density PCBs, it features visible gull-wing solder joints per DO-215AA, IPC/JEDEC Level 1 moisture sensitivity (no dry pack required), and withstands 8.3 ms non-repetitive surge currents up to 5.8 A - validated per MIL-STD-750 method 1020 for ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 17 V ±2% at IZT = 70 mA - precise regulation point for 15–19 V rail clamping or reference generation. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsinked lead; derates linearly above 25 °C. |
| Dynamic Impedance (ZZT) | 2.5 Ω at IZT = 70 mA - low AC impedance ensures stable output under varying load current ripple. |
| Max Regulator Current (IZM) | 5.8 mA - maximum continuous DC current before exceeding 5 W rating at full tolerance (VZM = 17.34 V). |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in automotive under-hood, industrial control, and outdoor power systems. |
| Thermal Resistance (RθJL) | 25 °C/W - enables direct thermal path from die to PCB lead, critical for sustained 5 W dissipation on FR4. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 12.2 V - negligible standby current in high-impedance bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; polarity: banded end is cathode (positive voltage applied to banded end for reverse conduction). Weight: 0.1 g. Moisture sensitivity level: IPC/JEDEC J-STD-020B Level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to system ground or lower-potential rail; forms reference return path during regulation. |
| Cathode | Reverse-bias input / regulated output node | Connected to voltage rail being clamped or referenced; carries full Zener current during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5354B equivalent | Identical electrical specs and test methods to legacy through-hole 1N5354B - simplifies redesign from axial to SMT. |
| ±2% voltage tolerance (C suffix) | Tighter regulation than ±5% (B) or ±10% (A) variants - reduces design margin needed for 17 V reference accuracy. |
| Gull-wing leads (DO-215AA) | Enables visual solder joint inspection and reliable reflow attachment on fine-pitch PCBs without tombstoning. |
| RoHS-compliant matte-tin plating | Meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020B - suitable for lead-free assembly processes up to 260 °C. |
| Non-ESD-sensitive construction | Qualified per MIL-STD-750 Method 1020 - no special handling required during board assembly or field service. |
Applications
| DC Power Rail Clamping | Low-Power Voltage Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5354B | Same VZ = 17 V, ±2%, but axial DO-204AL (T-18) package; RθJA = 120 °C/W vs. 90 °C/W for SMBG5354C/TR13. | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs. | Select when legacy through-hole compatibility or manual prototyping is prioritized over space and thermal performance. |
| SMBJ5354C | Same VZ, tolerance, and power rating, but DO-214AA (J-bend) package; RθJL = 30 °C/W vs. 25 °C/W for SMBG5354C/TR13. | Lower thermal efficiency and reduced surge current capability (IZSM = 5.5 A vs. 5.8 A); same RoHS compliance. | Select when existing DO-214AA footprint reuse is required, accepting marginal thermal penalty in compact layouts. |
Compared with 1N5354B and SMBJ5354C, SMBG5354C/TR13 offers superior thermal transfer (RθJL = 25 °C/W), visible gull-wing solder joints for AOI, and identical regulation specs - making it optimal for new SMT designs demanding reliability and manufacturability.

FAQ
What is the Zener voltage tolerance for SMBG5354C/TR13?
The "C" suffix in SMBG5354C/TR13 specifies a ±2% Zener voltage tolerance at IZT = 70 mA and TL = 25 °C. This yields a guaranteed VZ range of 16.66 V to 17.34 V, tighter than ±5% (B) or ±10% (A) variants - critical for precision reference applications where regulation accuracy directly impacts system error budget.
Can SMBG5354C/TR13 be used in place of 1N5354B?
Yes, SMBG5354C/TR13 is a direct surface-mount functional and electrical replacement for 1N5354B, with identical VZ, IZT, ZZT, and IZM specifications per Microsemi documentation. The only differences are package (DO-215AA vs. DO-204AL) and thermal resistance - SMBG5354C/TR13 offers better thermal performance (RθJL = 25 °C/W) but requires SMT reflow instead of through-hole soldering.
What is the maximum surge current rating for SMBG5354C/TR13?
SMBG5354C/TR13 has a maximum non-repetitive Zener surge current (IZSM) of 5.8 A for an 8.3 ms half-sine waveform, as specified in the Electrical Characteristics table. This rating applies under defined test conditions and supports protection against common transient events such as inductive kickback or ESD pulses in industrial environments.
Is SMBG5354C/TR13 RoHS compliant?
Yes, SMBG5354C/TR13 is RoHS compliant, indicated by the "e3" marking suffix per Microsemi's nomenclature guide. It uses annealed matte-tin plating per MIL-STD-750 Method 2026 and meets EU Directive 2011/65/EU - qualified for lead-free reflow up to 260 °C for 10 seconds.
What is the thermal resistance from junction to ambient for SMBG5354C/TR13?
The thermal resistance from junction to ambient (RθJA) for SMBG5354C/TR13 is 90 °C/W when mounted on a standard FR4 PCB with 1 oz copper and the recommended pad layout. This value assumes natural convection cooling; actual RθJA improves with added copper area or forced airflow, enabling sustained 5 W operation within safe junction temperature limits.
