Product details
Overview
SMBG5382C/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal Zener voltage of 140 V, ±2% tolerance (C suffix), 8.0 mA test current (IZT), 230 Ω dynamic impedance (ZZT), and 34 mA maximum regulator current (IZM) at TL < 25 °C - used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the SMBG5382C/TR13 datasheet, SMBG5382C/TR13 pinout, SMBG5382C/TR13 application, or SMBG5382C/TR13 equivalent, key selection criteria include Zener voltage accuracy, surge current capability (1500 A IZSM), thermal resistance (RθJL = 25 °C/W), RoHS-compliant matte-tin plating, and DO-215AA gull-wing package compatibility with automated SMT assembly.
Technical Context
This device operates as a silicon planar Zener diode in reverse-biased breakdown mode, delivering stable reference voltage across 1–100 mA operating current range with minimal voltage drift versus temperature (−65 to +150 °C junction range). Its low dynamic impedance (230 Ω at 8.0 mA) ensures tight regulation under varying load conditions.
The SMBG5382C/TR13 uses a void-free thermosetting epoxy case (UL94V-0), cathode band polarity marking, and gull-wing leads solderable per MIL-STD-750 Method 2026. It meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack required - and withstands 260 °C soldering for 10 s.
Key Specifications

FAQ
What is the Zener voltage tolerance of SMBG5382C/TR13?
The SMBG5382C/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its nominal 140 V Zener voltage is guaranteed between 137.2 V and 142.8 V at 8.0 mA test current and 25 °C. The tighter tolerance supports precision regulation in feedback and reference applications where ±5% devices would introduce unacceptable error margins. SMBG5382C/TR13 achieves this via tighter binning during final test.
Does SMBG5382C/TR13 require dry packing before reflow soldering?
No, SMBG5382C/TR13 does not require dry packing prior to reflow soldering. It carries IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1 rating, meaning it can be stored indefinitely at ≤30 °C/85% RH without baking. The DO-215AA package's void-free epoxy body and Level 1 classification eliminate moisture-related popcorning risk during standard 260 °C, 10 s reflow profiles. SMBG5382C/TR13 is ready for immediate SMT placement.
What is the maximum surge current rating for SMBG5382C/TR13?
The SMBG5382C/TR13 has a maximum non-repetitive Zener surge current (IZSM) rating of 1500 A for an 8.3 ms half-sine waveform. This value is measured under standardized transient conditions and reflects the device's ability to absorb short-duration overvoltage events without parametric shift or failure. Engineers use this rating to size clamping circuits protecting downstream ICs in motor drives or AC/DC converters. SMBG5382C/TR13 maintains this rating across its full operating temperature range.
How does the thermal resistance of SMBG5382C/TR13 affect its power dissipation?
SMBG5382C/TR13 has a junction-to-lead thermal resistance (RθJL) of 25 °C/W, enabling full 5.0 W power dissipation when lead temperature (TL) is held below 25 °C. At higher TL, power must be derated linearly per Figure 1 in the datasheet. For example, at TL = 75 °C, maximum allowable power drops to ~3.3 W. This RθJL value assumes mounting on FR4 with recommended pad layout; SMBG5382C/TR13 relies on lead-frame conduction rather than PCB copper area for heat removal.
Is SMBG5382C/TR13 compatible with lead-free reflow processes?
Yes, SMBG5382C/TR13 is fully compatible with lead-free reflow processes. Its RoHS-compliant annealed matte-tin plating (e3 marking) supports peak temperatures up to 260 °C for 10 seconds, meeting JEDEC J-STD-020D requirements. The gull-wing geometry ensures reliable wetting and joint formation with SAC305 and other lead-free pastes. SMBG5382C/TR13 has been qualified for standard reflow profiles including ramp-soak-reflow with Tp = 245–260 °C.
