Product details
Overview
SMBG5383CE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 150 V, ±2% tolerance (C suffix), rated test current of 8.0 mA, maximum dynamic impedance of 330 Ω at IZT, and peak surge current capability of 1500 A (8.3 ms half-sine). It regulates voltage in power supply overvoltage protection circuits for industrial DC rails.
For engineers reviewing the SMBG5383CE3/TR13 datasheet, SMBG5383CE3/TR13 pinout, SMBG5383CE3/TR13 application, or SMBG5383CE3/TR13 equivalent, key selection factors include Zener voltage accuracy, surge current rating, thermal resistance (RθJL = 25 °C/W), and DO-215AA gull-wing package compatibility with high-density PCB layouts.
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in DC power conditioning systems. Its 150 V Zener voltage is specified at 8.0 mA test current with ±2% tolerance, and it maintains regulation across junction temperatures from –65 °C to +150 °C.
The SMBG5383CE3/TR13 exhibits low dynamic impedance (330 Ω) near breakdown and supports high non-repetitive surge currents (1500 A, 8.3 ms) while maintaining stable reverse leakage (<0.5 µA at 108 V). Its DO-215AA gull-wing package enables visible solder joints and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±2% at 8.0 mA - ensures tight voltage clamping in 120–160 V DC bus protection. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management on FR4 board with recommended footprint. |
| Dynamic Impedance (ZZT) | 330 Ω max at IZT - limits voltage variation under load changes in regulation circuits. |
| Surge Current (IZSM) | 1500 A (8.3 ms half-sine) - withstands lightning-induced transients in industrial power inputs. |
| Reverse Leakage (IR) | <0.5 µA at 108 V - minimizes standby power loss in always-on protection stages. |
| Thermal Resistance (RθJL) | 25 °C/W - enables efficient heat transfer to PCB copper when lead-mounted per spec. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode indicated by band; banded end is anode in forward bias but functions as cathode terminal in Zener operation (i.e., cathode connects to higher potential during regulation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reference node for Zener conduction | Connected to lower-potential rail; reverse-biased during regulation to clamp voltage. |
| Cathode (unbanded end) | Input/regulated output node | Connected to protected circuit node; sinks current to maintain 150 V across load. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating (e3) | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirement. |
| Gull-wing lead form (DO-215AA) | Enables visual solder joint inspection and high-density placement on compact PCBs. |
| ±2% Zener voltage tolerance (C suffix) | Reduces design margin needed for overvoltage threshold setting in safety-critical rails. |
| 1500 A surge rating (8.3 ms) | Eliminates need for external MOVs in Class II industrial AC/DC front-end transient suppression. |
| Low leakage (<0.5 µA @ 108 V) | Preserves efficiency in battery-backed or energy-harvesting systems with long idle periods. |
Applications

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 electrical specs but no RoHS e3 marking; RθJA = 120 °C/W vs. 90 °C/W for SMBG. | Requires through-hole assembly and larger board area; unsuitable for automated SMT lines. | Select when legacy through-hole compatibility or higher ambient temperature derating margin is required. |
| SMBJ5383B | DO-214AA J-bend package; same VZ, tolerance, and surge rating; RθJL = 30 °C/W (vs. 25 °C/W) and RθJA = 100 °C/W. | Lower thermal performance demands more copper area for equivalent power handling. | Choose when existing DO-214AA footprint reuse is prioritized over optimal thermal transfer. |
Compared with SMBG5383CE3/TR13, 1N5383B offers identical regulation but lacks SMT compatibility and RoHS compliance, while SMBJ5383B trades 5 °C/W higher junction-to-lead resistance for footprint compatibility-making SMBG5383CE3/TR13 optimal for thermally constrained, high-volume SMT designs.

FAQ
What is the Zener voltage tolerance of SMBG5383CE3/TR13?
The SMBG5383CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 150 V Zener voltage is guaranteed between 147 V and 153 V when measured at 8.0 mA test current and TL = 25 °C. The tighter tolerance reduces design margin requirements in precision overvoltage detection circuits compared to ±5% (B) or ±10% (A) variants.
Does SMBG5383CE3/TR13 meet RoHS requirements?
Yes, SMBG5383CE3/TR13 complies with RoHS Directive 2011/65/EU, confirmed by the "e3" suffix indicating matte-tin plating. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and its DO-215AA package meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack.
What is the maximum surge current rating for SMBG5383CE3/TR13?
The SMBG5383CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1500 A, defined per an 8.3 ms half-sine waveform. This rating is validated under standard test conditions and enables use in industrial environments subject to lightning-induced transients or inductive load switching without additional external protection devices.
How does the thermal resistance of SMBG5383CE3/TR13 affect PCB layout?
SMBG5383CE3/TR13 has RθJL = 25 °C/W and RθJA = 90 °C/W when mounted on FR4 with the recommended pad layout. To sustain 5 W dissipation, designers must allocate ≥1.5 cm² of 1 oz copper connected to both leads, avoid thermal isolation, and follow the specified 8.13 mm × 2.16 mm pad dimensions to ensure reliable heat transfer and prevent junction overheating.
Can SMBG5383CE3/TR13 replace SMBJ5383B in an existing design?
SMBG5383CE3/TR13 can serve as a functional alternative to SMBJ5383B but is not a drop-in replacement due to different packages: SMBG uses DO-215AA gull-wing leads, while SMBJ uses DO-214AA J-bends. Layout revision is required to accommodate the 2.10 mm lead width and 4.57 mm body width of SMBG5383CE3/TR13 versus SMBJ's dimensions.
