Product details
Overview
SMBG5363B/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 30 V, ±5% tolerance (B suffix), 8.0 Ω dynamic impedance at 40 mA test current, and maximum regulator current of 158 mA. It operates across –65 °C to +150 °C junction temperature and is used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5363B/TR13 datasheet, SMBG5363B/TR13 pinout, SMBG5363B/TR13 application, or SMBG5363B/TR13 equivalent, this page delivers verified electrical specs, DO-215AA gull-wing package details, thermal derating behavior, and validated alternative parts for voltage reference and clamping designs requiring stable 30 V regulation under varying load and temperature conditions.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse-biased breakdown mode. Its Zener voltage is specified at 30 V ±5% with 40 mA test current (IZT), and it maintains low dynamic impedance (8.0 Ω) near the knee region, ensuring minimal voltage variation across regulated current changes.
Thermal performance is defined by RθJL = 25 °C/W (junction-to-lead) and RθJA = 90 °C/W (junction-to-ambient on FR4), enabling 5.0 W dissipation only when lead temperature remains below 25 °C - critical for PCB layout and heatsinking decisions in high-reliability power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at 40 mA - defines precise clamping threshold for 28.5–31.5 V operation |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires thermal management via copper pour or short leads to sustain full rating |
| Dynamic Impedance (ZZT) | 8.0 Ω at IZT = 40 mA - ensures <100 mV output shift per 10 mA load change in regulation zone |
| Max Regulator Current (IZM) | 158 mA - sets upper limit for continuous DC current without exceeding 5 W at 30 V |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 21.6 V - guarantees negligible standby current in high-impedance sensing paths |
| Surge Current (IZSM) | 3.7 A (8.3 ms half-sine) - supports transient overvoltage suppression in surge-prone industrial inputs |
| Junction Temperature Range | –65 °C to +150 °C - enables deployment in automotive engine control units and outdoor telecom equipment |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode (unbanded end) and cathode (banded end); polarity must be observed during PCB placement to ensure correct reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; reference ground node in reverse-bias regulation | Connected to lower-potential side of regulated circuit; determines return path for Zener current |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse-bias mode | Connected to voltage rail being stabilized; provides 30 V reference point relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5363B equivalent | Identical electrical specs and test methods - allows drop-in replacement in legacy designs qualified to MIL-STD-750 |
| Gull-wing lead form | Visible solder joints enable automated optical inspection (AOI) and rework accessibility on dense PCBs |
| Moisture sensitivity Level 1 | No dry pack or baking required before reflow - reduces manufacturing handling cost and floor life constraints |
| RoHS-compliant matte-tin plating | Lead-free assembly compatible with Pb-free SAC305 solder profiles up to 260 °C for 10 s |
| High surge current capability | 3.7 A non-repetitive peak withstand - protects downstream ICs from lightning-induced transients in AC/DC front-ends |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Stabilizing error amplifier reference in isolated flyback converter feedback network. IC Role / Device Role / Timing Role: Voltage reference element setting 30 V clamp on optocoupler input side. Use Value: Maintains ±0.5% output regulation across line/load variations due to tight 5% VZ tolerance and low 8.0 Ω ZZT. | Use Scenario: Protecting 24 V analog input channel from ESD and overvoltage events in PLC I/O module. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor (TVS) configured as unidirectional Zener clamp. Use Value: Limits input voltage to ≤31.5 V while drawing <0.5 µA leakage at 21.6 V - preserves signal integrity in high-impedance sensor interfaces. |
| Automotive Body Control Module | Telecom Line Card Protection |
Use Scenario: Regulating auxiliary 30 V rail for window lift motor driver logic in 12 V vehicle architecture. IC Role / Device Role / Timing Role: Primary voltage reference for LDO pre-regulator feeding microcontroller subsystem. Use Value: Operates reliably from –40 °C to +125 °C ambient with no derating loss up to 100 °C case temperature - meets AEC-Q101 stress requirements. | Use Scenario: Clamping ringing voltage on -48 V DC telecom power bus during hot-swap insertion. IC Role / Device Role / Timing Role: Standby shunt regulator absorbing inrush energy during board insertion. Use Value: Withstands 3.7 A surge (8.3 ms) without degradation - prevents latch-up in upstream DC/DC converters during field maintenance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5363B | Axial-leaded T-18 package; identical VZ, IZT, ZZT, and PD specs; higher RθJA (~150 °C/W) | Requires through-hole mounting and manual assembly; unsuitable for high-density SMT lines | Select when legacy through-hole design or hand-soldered prototyping is required |
| SMBJ5363 | DO-214AA J-bend package; same VZ and tolerance; 5 W rating but lower IZM (140 mA vs. 158 mA) | Compatible footprint on same PCB layer but different pad geometry; slightly reduced surge margin | Select when existing DO-214AA layout exists and 3.5 A surge rating suffices |
Compared with SMBG5363B/TR13, 1N5363B offers identical regulation performance but demands through-hole assembly, while SMBJ5363 fits J-bend layouts with minor derating in max continuous current and surge handling - choose SMBG5363B/TR13 for optimal thermal performance and AOI-friendly gull-wing reliability in new SMT designs.

FAQ
What is the Zener voltage tolerance for SMBG5363B/TR13?
The "B" suffix in SMBG5363B/TR13 indicates ±5% Zener voltage tolerance, meaning its breakdown voltage is guaranteed between 28.5 V and 31.5 V when measured at 40 mA test current and 25 °C lead temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet, and applies identically to SMBG5363B/TR13 as part of the SMBG5333B–SMBG5388B family.
Does SMBG5363B/TR13 require dry packing before reflow soldering?
No, SMBG5363B/TR13 does not require dry packing before reflow soldering. Its moisture sensitivity level is rated IPC/JEDEC J-STD-020B Level 1, which means it can be stored indefinitely at ≤30 °C/60% RH without baking. This is explicitly stated in the Maximum Ratings table and Mechanical/Packaging section of the official Microsemi datasheet for SMBG5333B–SMBG5388B.
What is the maximum continuous Zener current for SMBG5363B/TR13?
The maximum continuous Zener current (IZM) for SMBG5363B/TR13 is 158 mA, derived from its 5.0 W power rating and upper-limit Zener voltage (31.5 V). This value is listed in the Electrical Characteristics table on page 3 of the Microsemi datasheet and assumes lead temperature remains below 25 °C - exceeding this current risks thermal runaway unless adequate copper thermal relief is provided.
Can SMBG5363B/TR13 be used as a transient voltage suppressor?
Yes, SMBG5363B/TR13 can be used as a unidirectional transient voltage suppressor, with a specified non-repetitive surge current (IZSM) of 3.7 A for an 8.3 ms half-sine waveform. Its low dynamic impedance (8.0 Ω) and fast response in breakdown make it effective for clamping short-duration overvoltages, though dedicated TVS diodes may offer superior clamping ratio and bidirectional capability.
What package type does SMBG5363B/TR13 use?
SMBG5363B/TR13 uses the DO-215AA gull-wing surface-mount package, as confirmed in the Mechanical and Packaging section of the Microsemi datasheet. This package features visible solder joints, void-free epoxy encapsulation meeting UL94V-0, and a 12 mm tape-and-reel configuration indicated by the "TR13" suffix - standard per EIA-481-1-A for automated pick-and-place assembly.
