Product details
Overview
SMBG5360AE3/TR13 from Microsemi is a surface-mount 5 W Zener diode with nominal breakdown voltage of 25 V, ±10% tolerance (A suffix), and DO-215AA gull-wing package. It regulates voltage across wide current and temperature ranges, supports surge currents up to 110 A (8.3 ms half-sine), and is used in power supply overvoltage clamping and reference circuits.
For engineers reviewing the SMBG5360AE3/TR13 datasheet, SMBG5360AE3/TR13 pinout, SMBG5360AE3/TR13 application, or SMBG5360AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (RθJL = 25 °C/W), maximum regulator current (IZM = 110 mA), surge capability, and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse-biased breakdown mode with specified test current IZT = 50 mA and dynamic impedance ZZT = 4.0 Ω at that point. Its knee impedance ZZK is 75 Ω at 1.0 mA, indicating stable regulation onset.
Thermal design relies on junction-to-lead resistance of 25 °C/W and junction-to-ambient resistance of 90 °C/W when mounted on FR4 with recommended footprint. Power derating begins above 25 °C lead temperature, with full 5.0 W dissipation only below that threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±10% at IZT = 50 mA - defines precise clamping level for overvoltage protection circuits |
| Power Dissipation (PD) | 5.0 W at TL ≤ 25 °C - requires thermal management via PCB copper area or heatsinking for sustained operation |
| Dynamic Impedance (ZZT) | 4.0 Ω at IZT = 50 mA - ensures low voltage variation under load current changes |
| Max Regulator Current (IZM) | 110 mA - sets upper limit for continuous DC bias without exceeding power rating |
| Surge Current (IZSM) | 110 A (8.3 ms half-sine) - enables transient suppression of high-energy spikes like ESD or lightning-induced surges |
| Junction Temperature Range | –65 to +150 °C - supports operation in industrial and automotive under-hood environments |
| Moisture Sensitivity Level | Level 1 per J-STD-020B - eliminates need for dry pack or baking prior to reflow |
Pinout & Package
DO-215AA gull-wing surface-mount package with cathode band marking; terminals are anode and cathode, with cathode identified by banded end - must be biased with banded end positive relative to anode for Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference/ground node in Zener clamp configuration | Connected to lower-potential side of protected circuit; forms return path for regulation current |
| Cathode | Input/regulated output node | Banded terminal; connected to higher-potential rail being clamped or referenced; carries full Zener current |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC 1N5360B equivalent | Identical electrical characteristics and testing - enables drop-in replacement in legacy designs qualified to 1N5360B |
| RoHS-compliant matte-tin plating | e3 suffix indicates annealed matte-tin finish compliant with RoHS Directive 2011/65/EU - suitable for lead-free reflow assembly |
| Gull-wing lead form | DO-215AA package with visible solder joints - supports automated optical inspection (AOI) and improves solder joint reliability verification |
| Level 1 moisture sensitivity | No dry pack required - reduces handling cost and eliminates pre-reflow baking step in manufacturing |
| High surge current rating | 110 A non-repetitive peak (8.3 ms half-sine) - provides robust transient immunity without external TVS augmentation |
Applications
| DC Power Supply Clamping | Industrial Sensor Reference |
|---|---|
Use Scenario: Protection of 24 V DC input rails against load dump or inductive switching transients in PLC modules. IC Role / Device Role / Timing Role: Voltage clamp limiting rail excursions to ≤27.5 V (25 V +10%) during surge events. Use Value: Prevents damage to downstream regulators and microcontrollers without requiring additional transient suppressors. |
Use Scenario: Stable 25 V reference for analog front-end conditioning of 4–20 mA current loop sensors. IC Role / Device Role / Timing Role: Precision voltage reference source with minimal drift over –40 to +85 °C operating range. Use Value: Enables <1% total error in sensor signal chain due to tight 10% VZ tolerance and low ZZT. |
| Automotive Body Control Unit | Telecom Line Card Protection |
Use Scenario: Overvoltage suppression on LIN bus power lines exposed to battery transients up to ±100 V. IC Role / Device Role / Timing Role: Primary clamping element absorbing energy from ISO 7637-2 Pulse 1 and Pulse 2a events. Use Value: Meets automotive EMC requirements with single-device solution, reducing BOM count versus multi-stage protection. |
Use Scenario: Secondary protection stage after primary gas discharge tube on POTS line interface cards. IC Role / Device Role / Timing Role: Fast-response Zener clamp limiting residual surge to <30 V at telecom IC inputs. Use Value: Extends lifetime of line drivers and codec ICs by limiting peak stress below absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | Same VZ = 25 V ±10%, same IZT = 50 mA, but axial DO-204AL (T-18) package - no surface-mount compatibility | Requires through-hole PCB layout and wave soldering; unsuitable for high-density SMT assemblies | Select when retrofitting legacy through-hole designs or where manual assembly is preferred. |
| SMBJ5360B | Same VZ, same power rating, but DO-214AA (J-bend) package - different footprint and thermal path (RθJA = 100 °C/W vs. 90 °C/W) | Lower thermal performance on identical PCB; may require larger copper area for equivalent power handling | Select when existing DO-214AA footprint is fixed and board redesign is not feasible. |
Compared with SMBG5360AE3/TR13, 1N5360B offers identical regulation specs but mandates through-hole assembly, while SMBJ5360B fits J-bend layouts but delivers 11% higher thermal resistance - making SMBG5360AE3/TR13 optimal for new SMT designs needing visible solder joints and best-in-class RθJL.

FAQ
What is the Zener voltage tolerance for SMBG5360AE3/TR13?
The SMBG5360AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in the part number. Its nominal VZ is 25 V, meaning the actual breakdown voltage falls between 22.5 V and 27.5 V when measured at IZT = 50 mA and TL = 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0246-1 datasheet.
Is SMBG5360AE3/TR13 RoHS compliant?
Yes, SMBG5360AE3/TR13 is RoHS compliant, as indicated by the "e3" suffix. It features annealed matte-tin plating per MIL-STD-750, method 2026, and meets the requirements of Directive 2011/65/EU. The device requires no dry pack and is rated Moisture Sensitivity Level 1 per J-STD-020B.
What is the maximum continuous Zener current for SMBG5360AE3/TR13?
The maximum continuous regulator current (IZM) for SMBG5360AE3/TR13 is 110 mA. This value is derived from its 5.0 W power rating and upper-limit Zener voltage (25 V × 1.1 = 27.5 V), per Note 3 in the datasheet. Operation above this current risks thermal runaway unless adequate heatsinking is provided.
Does SMBG5360AE3/TR13 have a specified surge current rating?
Yes, SMBG5360AE3/TR13 has a non-repetitive peak surge current (IZSM) rating of 110 A for an 8.3 ms half-sine waveform, as stated in the Electrical Characteristics table. This rating enables reliable suppression of high-energy transients such as ISO 7637-2 Pulse 5a without degradation.
What package type does SMBG5360AE3/TR13 use?
SMBG5360AE3/TR13 uses the DO-215AA gull-wing surface-mount package. Its dimensions are specified on page 5 of the datasheet: length 1.96–2.10 mm, width 4.06–4.57 mm, height 3.30–3.94 mm. The gull-wing leads enable visual solder joint inspection and comply with EIA-481-1-A tape-and-reel packaging (TR13 denotes 12 mm tape).
