Product details
Overview
SMBG5384C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 160 V, ±2% tolerance (C suffix), 8.0 mA test current (IZT), and 350 Ω maximum dynamic impedance (ZZT) at IZT - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5384C/TR13 datasheet, SMBG5384C/TR13 pinout, SMBG5384C/TR13 application, or SMBG5384C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1650 A), thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates as a reverse-biased silicon Zener diode with sharp breakdown knee at 160 V, specified at 8.0 mA test current and 30 °C lead temperature. Its 350 Ω dynamic impedance ensures stable regulation under varying load currents, and its 1650 A non-repetitive surge rating (8.3 ms half-sine) supports transient suppression in DC bus lines.
The SMBG5384C/TR13 uses a void-free UL94V-0 epoxy case with gull-wing leads, cathode indicated by band, and moisture sensitivity level 1 - eliminating dry-pack requirements. Thermal resistance junction-to-lead is 25 °C/W, enabling reliable 5 W dissipation with adequate PCB copper heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±2% at 8.0 mA - enables precise reference in high-voltage feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via PCB copper pour or heatsink |
| Dynamic Impedance (ZZT) | 350 Ω max at 8.0 mA - limits output voltage variation under load current changes |
| Maximum Surge Current (IZSM) | 1650 A (8.3 ms half-sine) - protects downstream circuitry from short-duration transients |
| Junction Temperature Range | –65 to +150 °C - suitable for industrial and automotive under-hood environments |
| Thermal Resistance (RθJL) | 25 °C/W - allows direct thermal path to PCB lead for efficient heat transfer |
| Reverse Leakage (IR) | 0.5 µA at 122 V - ensures minimal standby power loss in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5384B | Same 160 V ±5% (B suffix), 5 W, DO-41 axial package; higher 500 Ω ZZT; no RoHS compliance by default | Requires through-hole mounting and manual assembly; less suitable for high-density SMT production | Select when legacy through-hole design or non-RoHS compliance is acceptable |
| SMBJ5384C | Same 160 V ±2%, 5 W, but DO-214AA J-bend package; 350 Ω ZZT; identical RoHS finish | Lower profile than SMBG; different pad layout; slightly higher RθJA (100 °C/W vs. 90 °C/W) | Select when board space constraints favor J-bend footprint or existing DO-214AA layout reuse is needed |
Compared with SMBG5384C/TR13, 1N5384B trades SMT compatibility and tighter tolerance for axial mounting flexibility, while SMBJ5384C offers identical regulation performance in a mechanically distinct surface-mount form factor requiring different PCB land patterns.

FAQ
What is the Zener voltage tolerance of SMBG5384C/TR13?
The SMBG5384C/TR13 has a ±2% Zener voltage tolerance, confirmed by the "C" suffix in its part number per Microsemi's nomenclature. This means its rated 160 V Zener voltage falls between 156.8 V and 163.2 V at 8.0 mA test current and 30 °C lead temperature. The SMBG5384C/TR13 achieves tighter regulation than ±5% variants like SMBG5384B, reducing calibration burden in precision applications.
Does SMBG5384C/TR13 require dry packing before reflow soldering?
No, SMBG5384C/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ambient conditions (≤30 °C / 60% RH) without desiccant or dry cabinet. This eliminates pre-reflow baking steps, reducing manufacturing cost and process complexity for SMBG5384C/TR13 integration.
What is the maximum surge current rating for SMBG5384C/TR13?
The SMBG5384C/TR13 is rated for 1650 A maximum non-repetitive surge current (IZSM) using an 8.3 ms half-sine waveform, as specified in Microsemi's T4-LDS-0246-1 datasheet. This rating applies under defined test conditions and reflects the device's ability to absorb transient energy without failure - critical for SMBG5384C/TR13 use in DC bus clamping applications.
Is SMBG5384C/TR13 RoHS compliant?
Yes, SMBG5384C/TR13 is RoHS compliant, indicated by the "e3" designation in Microsemi's full part numbering system and confirmed in the datasheet's features section. It uses annealed matte-tin plating per MIL-STD-750 Method 2026 and meets EU Directive 2011/65/EU requirements - verified for SMBG5384C/TR13 shipments from Aetrix Electronics.
How does the DO-215AA package of SMBG5384C/TR13 differ from DO-214AA?
The DO-215AA package of SMBG5384C/TR13 uses gull-wing leads, while DO-214AA (used in SMBJ5384C) uses J-bend leads. Gull-wing leads provide visible solder joints for automated optical inspection and easier rework, whereas J-bend leads offer lower profile and higher density. Both are surface-mount, but SMBG5384C/TR13 requires distinct PCB pad geometry per Microsemi's recommended footprint.
