Product details
Overview
SMBG5383C/TR13 from Microsemi is a surface-mount 5 W Zener diode with a nominal Zener voltage of 150 V, ±2% tolerance (suffix C), rated for 8.0 mA test current (IZT), 330 Ω dynamic impedance (ZZT), and 31.6 mA maximum regulator current (IZM). It operates in the DO-215AA gull-wing package and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5383C/TR13 datasheet, SMBG5383C/TR13 pinout, SMBG5383C/TR13 application, or SMBG5383C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1500 A @ 8.3 ms), thermal resistance (25 °C/W junction-to-lead), moisture sensitivity level (MSL Level 1), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, with specified regulation at IZT = 8.0 mA and VZ = 150 V. Its low dynamic impedance (330 Ω) ensures stable voltage under varying load currents, while its 1500 A non-repetitive surge rating supports transient suppression in industrial power rails.
The SMBG5383C/TR13 uses a void-free UL94V-0 epoxy body and gull-wing leads compatible with standard SMT reflow profiles (260 °C/10 s). It exhibits minimal voltage drift over temperature (−65 to +150 °C junction range) and maintains leakage current ≤0.5 µA at VR = 108 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±2% at IZT = 8.0 mA - defines precise regulation point for feedback networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management when mounted on FR4 with recommended footprint |
| Dynamic Impedance (ZZT) | 330 Ω at IZT = 8.0 mA - limits output voltage variation under load transients |
| Max Regulator Current (IZM) | 31.6 mA - maximum continuous DC current before exceeding 5 W rating at high-end VZ |
| Surge Current (IZSM) | 1500 A (8.3 ms half-sine) - enables single-event overvoltage clamping without failure |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 108 V - ensures low standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJL) | 25 °C/W - allows direct thermal path to PCB copper for reliable power handling |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5383B equivalent | Direct functional replacement for legacy axial 1N5383B with identical electrical specs and testing |
| MSL Level 1 rating | No dry pack required - simplifies SMT handling and eliminates bake-out prior to assembly |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B solderability standards without lead content |
| Gull-wing lead form | Enables visual solder joint inspection and reduces tombstoning risk during reflow |
| High surge current capability | 1500 A peak (8.3 ms) supports robust protection in 48 V telecom and industrial DC bus applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5383B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and IZM specs per JEDEC spec | Requires through-hole assembly; not suitable for high-density SMT layouts | Select when legacy board design or manual repair mandates axial form factor |
| SMBJ5383C | DO-214AA J-bend package; same VZ, tolerance, and power rating but higher RθJA (90 °C/W vs. 25 °C/W) | Limited thermal performance in high-power continuous operation without enhanced copper pour | Select when footprint compatibility with SMBJ series is required and thermal margin permits |
Compared with SMBG5383C/TR13, the 1N5383B offers identical regulation performance but lacks SMT manufacturability, while the SMBJ5383C sacrifices thermal efficiency for J-bend mounting flexibility-making SMBG5383C/TR13 optimal for thermally constrained, high-reliability SMT designs.

FAQ
What is the Zener voltage tolerance for SMBG5383C/TR13?
The SMBG5383C/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its regulated voltage falls within 147 V to 153 V when tested at 8.0 mA (IZT) and 25 °C. The tighter tolerance supports precision feedback applications where output stability is critical, such as in medical power supplies or calibrated instrumentation referencing SMBG5383C/TR13.
Does SMBG5383C/TR13 require dry packing before SMT assembly?
No, SMBG5383C/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without dry packing or baking. This eliminates pre-reflow moisture mitigation steps, reducing manufacturing cost and cycle time for production lines using SMBG5383C/TR13 in high-volume SMT processes.
What is the maximum surge current rating for SMBG5383C/TR13?
The SMBG5383C/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1500 A at an 8.3 ms half-sine waveform. This rating is validated per Microsemi's characterization and enables SMBG5383C/TR13 to absorb high-energy transients in telecom DC distribution, motor drive snubbers, and industrial PLC input protection without degradation-provided proper PCB thermal relief is applied.
How does the thermal resistance of SMBG5383C/TR13 compare between junction-to-lead and junction-to-ambient?
SMBG5383C/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W when mounted on FR4 with the recommended footprint. The lower RθJL confirms efficient heat transfer from die to lead frame, making SMBG5383C/TR13 suitable for conduction-cooled designs, whereas RθJA reflects worst-case natural convection-so SMBG5383C/TR13 must be used with adequate copper pour or heatsinking for sustained 5 W operation.
Is SMBG5383C/TR13 RoHS compliant?
Yes, SMBG5383C/TR13 is RoHS compliant, as confirmed by the "e3" marking designation and matte-tin plating per MIL-STD-750 Method 2026. The "C" suffix denotes ±2% tolerance, and the "TR13" indicates EIA-481-1-A tape-and-reel packaging with 12 mm carrier tape-ensuring SMBG5383C/TR13 meets environmental compliance requirements for global electronics manufacturing.
