Product details
Overview
SMBG5383B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 150 V, ±5% tolerance (B suffix), 8.0 mA test current (IZT), and 330 Ω dynamic impedance (ZZT) - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5383B/TR13 datasheet, SMBG5383B/TR13 pinout, SMBG5383B/TR13 application, or SMBG5383B/TR13 equivalent, key selection criteria include Zener voltage accuracy at 150 V, thermal resistance (RθJL = 25 °C/W), surge current rating (1500 A), moisture sensitivity level (MSL Level 1), and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable reference voltage across wide current (8–144 mA) and temperature (–65 to +150 °C) ranges. Its low dynamic impedance (330 Ω at IZT) ensures minimal voltage variation under load transients.
The SMBG5383B/TR13 uses a void-free thermosetting epoxy case (UL94V-0), matte-tin RoHS-compliant plating, and cathode band polarity marking. It meets MIL-STD-750 ESD robustness requirements and withstands non-repetitive 8.3 ms half-sine surge currents up to 1500 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±5% - precise regulation point for high-voltage feedback networks |
| Test Current (IZT) | 8.0 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZT) | 330 Ω - low AC impedance ensures stable regulation under small-signal ripple |
| Max Regulator Current (IZM) | 31.6 mA - maximum DC current at rated 5 W dissipation with proper lead heatsinking |
| Surge Current (IZSM) | 1500 A - peak non-repetitive surge handling for transient overvoltage clamping |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer from junction to PCB lead, critical for sustained 5 W operation |
| Moisture Sensitivity | Level 1 per J-STD-020B - no dry pack required, supports standard SMT reflow without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5383B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM specs but higher RθJA (150 °C/W vs. 90 °C/W) | Requires through-hole mounting and manual assembly; unsuitable for high-density SMT designs | Select SMBG5383B/TR13 for automated production and thermal performance; choose 1N5383B only for legacy repair or prototyping with through-hole boards |
| SMBJ5383B | DO-214AA J-bend package; same electrical specs but different footprint and slightly higher RθJA (100 °C/W) | Compatible with existing SMBJ land patterns but lacks gull-wing visibility for AOI inspection | Prefer SMBG5383B/TR13 when visual solder verification or lowest thermal resistance is required; SMBJ5383B suits space-constrained layouts where J-bend fits better |
Compared with 1N5383B and SMBJ5383B, the SMBG5383B/TR13 delivers superior thermal performance (RθJL = 25 °C/W) and process compatibility (MSL Level 1, gull-wing leads), making it optimal for volume-manufactured industrial power and control systems requiring long-term stability and automated optical inspection support.

FAQ
What is the Zener voltage tolerance of SMBG5383B/TR13?
The "B" suffix in SMBG5383B/TR13 denotes a ±5% Zener voltage tolerance. At 25 °C, its nominal breakdown voltage is 150 V, meaning the actual VZ falls between 142.5 V and 157.5 V under specified test conditions (IZT = 8.0 mA). This tolerance is verified per JEDEC standards and matches the 1N5383B specification.
Can SMBG5383B/TR13 be used in place of 1N5383B?
Yes, SMBG5383B/TR13 is the surface-mount equivalent of 1N5383B with identical electrical characteristics, including VZ, IZT, ZZT, and IZM. However, SMBG5383B/TR13 uses a DO-215AA gull-wing package versus the axial T-18 package of 1N5383B - requiring PCB layout change but enabling automated SMT assembly and improved thermal conduction via leads.
What is the maximum continuous power dissipation for SMBG5383B/TR13?
SMBG5383B/TR13 is rated for 5.0 W off-state power dissipation at TL < 25 °C. When mounted on an FR4 board with recommended footprint, derating begins above 25 °C per the power derating curve: at 75 °C lead temperature, maximum allowable power drops to ~3.3 W. Full 5 W operation requires adequate lead heatsinking.
Is SMBG5383B/TR13 RoHS compliant?
Yes, SMBG5383B/TR13 features RoHS-compliant annealed matte-tin plating per the "e3" designation implied by the TR13 tape-and-reel suffix and confirmed in Microsemi's documentation. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and meets JEDEC J-STD-020B MSL Level 1 requirements without dry packing.
What does the "TR13" suffix indicate in SMBG5383B/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-481-1-A standard using a 12 mm carrier tape. "TR" denotes tape-and-reel format, and "13" specifies the standard reel size (13-inch diameter). This configuration supports automated pick-and-place assembly and is compatible with industry-standard SMT feeders.
