Product details
Overview
SMBG5383BE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 150 V, ±5% tolerance (B suffix), RoHS-compliant matte-tin plating (e3), and DO-215AA gull-wing package. It delivers stable voltage regulation at 8.0 mA test current (IZT), exhibits 330 Ω dynamic impedance (ZZT), and supports up to 1.1 A non-repetitive surge current (IZSM) for transient protection in power supply rails.
For engineers reviewing the SMBG5383BE3/TR13 datasheet, SMBG5383BE3/TR13 pinout, SMBG5383BE3/TR13 application, or SMBG5383BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJL = 25 °C/W), maximum regulator current (IZM = 31.6 mA), surge capability (8.3 ms half-sine), and moisture sensitivity level (MSL Level 1, no dry pack required).
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased mode, with cathode indicated by band and rated for junction temperatures from –65 °C to +150 °C. Its DO-215AA gull-wing package enables visible solder joints and high-density PCB placement while maintaining 5.0 W power dissipation at lead temperature <25 °C.
The SMBG5383BE3/TR13 exhibits low dynamic impedance (330 Ω at IZT = 8.0 mA) and minimal voltage drift over current-critical for stable reference generation. Reverse leakage remains ≤0.5 µA at VR = 108 V, and forward voltage is 1.2 V at 1.0 A, supporting bidirectional ESD robustness per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±5% at IZT = 8.0 mA - defines precise clamping threshold for overvoltage protection circuits. |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or heatsinked lead for sustained operation. |
| Dynamic Impedance (ZZT) | 330 Ω at IZT = 8.0 mA - determines regulation stiffness; lower values improve load/line transient response. |
| Max Surge Current (IZSM) | 1.1 A (8.3 ms half-sine) - enables single-event transient suppression without degradation. |
| Thermal Resistance (RθJL) | 25 °C/W - allows direct thermal path from junction to PCB lead, critical for reliability under pulsed loads. |
| Moisture Sensitivity | Level 1 per J-STD-020B - eliminates dry-pack requirement and reflow baking steps during assembly. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 108 V - ensures minimal standby power loss in high-impedance bias networks. |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode identified by molded band; terminals are anode (unbanded end) and cathode (banded end). Designed for visible solder joint inspection and compatible with standard SMT reflow profiles (peak 260 °C for 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; reference ground node in reverse-bias regulation | Connected to system ground or low-impedance return path; must handle full surge current during clamping. |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse-bias operation | Banded end connects to protected rail; voltage at this node is stabilized at 150 V ±5% across operating current range. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5383B equivalence | Identical electrical specs and test methods to legacy through-hole 1N5383B - enables drop-in replacement in upgraded designs. |
| Gull-wing leadform (DO-215AA) | Enables automated optical inspection (AOI) of solder joints and improves mechanical reliability vs. J-bend packages. |
| RoHS-compliant matte-tin plating (e3) | Eliminates lead-based solder compatibility concerns and meets global environmental compliance mandates. |
| MSL Level 1 rating | Supports unlimited floor life and standard reflow without preconditioning - reduces manufacturing overhead. |
| High IZSM / IZM ratio (1.1 A / 31.6 mA) | Provides >35× surge margin over steady-state current - suitable for lightning-induced transients in industrial power supplies. |
Applications
| Industrial Power Supply Protection | Automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5383B | Through-hole DO-41 package; identical VZ, IZT, ZZT, and IZM specs; non-RoHS (Sn/Pb plating). | Requires axial or radial through-hole PCB layout; unsuitable for high-density SMT designs. | Select when legacy board reuse or manual prototyping is prioritized over automated assembly. |
| SMBJ5383B | J-bend DO-214AA package; same electrical specs but higher RθJA (100 °C/W vs. 90 °C/W); different pad layout. | Lower thermal performance in ambient-convection environments; less visible solder joints than gull-wing. | Select when existing DO-214AA footprint exists and thermal derating margins exceed 15%. |
Compared with SMBG5383BE3/TR13, 1N5383B offers identical regulation performance but lacks SMT compatibility and RoHS compliance, while SMBJ5383B trades gull-wing inspectability and slightly better thermal resistance for J-bend mount flexibility.

FAQ
What is the Zener voltage tolerance of SMBG5383BE3/TR13?
The SMBG5383BE3/TR13 has a ±5% Zener voltage tolerance, indicated by the "B" suffix in the part number. This means its breakdown voltage is guaranteed between 142.5 V and 157.5 V when tested at 8.0 mA (IZT) and 25 °C. The e3 suffix confirms RoHS-compliant matte-tin plating, and TR13 denotes tape-and-reel packaging per EIA-481-1-A standard.
How does SMBG5383BE3/TR13 compare to the through-hole 1N5383B?
SMBG5383BE3/TR13 matches the 1N5383B in all electrical specifications-including 150 V Zener voltage, 8.0 mA test current, 330 Ω dynamic impedance, and 31.6 mA maximum regulator current-but uses a DO-215AA gull-wing surface-mount package instead of DO-41. It also features RoHS-compliant plating (e3) versus Sn/Pb on the 1N5383B, making SMBG5383BE3/TR13 suitable for modern automated assembly.
What is the maximum surge current rating for SMBG5383BE3/TR13?
The SMBG5383BE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 1.1 A, defined as a single 8.3 ms half-sine waveform. This rating assumes proper PCB thermal design (FR4 with 1 oz Cu and recommended pad layout). Exceeding this value risks irreversible junction damage, even if average power remains within 5 W limits.
Does SMBG5383BE3/TR13 require dry packing before reflow soldering?
No, SMBG5383BE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it has unlimited floor life and does not require dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates moisture-related popcorning failures during standard SMT reflow profiles peaking at 260 °C for 10 seconds.
What is the thermal resistance from junction to lead (RθJL) for SMBG5383BE3/TR13?
The SMBG5383BE3/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, measured under specified mounting conditions. This parameter enables direct thermal modeling from die to PCB copper, supporting accurate derating calculations when ambient or lead temperature exceeds 25 °C. Its RθJA is 90 °C/W on FR4 with recommended footprint.
