Product details
Overview
SMBG13A-M3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG13A-M3/52 datasheet, SMBG13A-M3/52 pinout, SMBG13A-M3/52 application, or SMBG13A-M3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance (M3 suffix), low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR to limit transient energy. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ps), while M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance.
Rated for -55 °C to +150 °C junction temperature, it supports high-reliability applications requiring repetitive surge handling up to 0.01% duty cycle. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling effective heat dissipation under transient stress on standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - guaranteed breakdown threshold defining turn-on precision |
| VC @ IPPM | 21.5 V at 27.9 A - clamped voltage during 600 W transient, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform per JEDEC standards |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine, unidirectional only) |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | SMBG (DO-215AA) - surface-mount package with 0.235" × 0.255" footprint and gull-wing leads |
Pinout & Package
SMBG13A-M3/52 uses the SMBG (DO-215AA) package: low-profile, gull-wing leaded case with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD22-B102, and meet MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit terminal in forward bias; marked by band on package body | Connected to protected line (e.g., 12 V rail or CAN-H); defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Halogen-free (M3 suffix) | Meets IEC 61249-2-21 and JESD201 Class 2 whisker resistance requirements for long-term interconnect integrity |
| 600 W peak pulse power | Withstands ISO 7637-2 Pulse 1/2a/3a transients and IEC 61000-4-5 Level 4 surges without degradation |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during clamping, protecting 15 V-tolerant ICs such as LIN transceivers and microcontrollers |
| MSL Level 1 rating | Enables direct placement into reflow ovens without dry-pack or baking, reducing manufacturing overhead |
Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Digital Input Protection |
|---|---|

Use Scenario: Safeguarding analog output (0–5 V) of engine oil pressure sensors exposed to ignition noise and relay switching. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 200 pF typical) placed adjacent to sensor IC pins to suppress EFT bursts without distorting signal bandwidth. Use Value: Clamps transients to ≤21.5 V while maintaining <1 nA leakage at 13 V, preserving ADC accuracy and offset stability. | Use Scenario: Protecting gate drive signals of MOSFET half-bridges in washing machine motor inverters from cross-conduction spikes. IC Role / Device Role / Timing Role: Unidirectional TVS on high-side gate resistor node, referenced to floating source potential. Use Value: Withstands 100 A IFSM surge events and maintains clamping performance after repeated 8.3 ms half-sine stress, extending driver IC lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG13A-E3/52 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3) | Lacks halogen-free certification; unsuitable for strict environmental compliance programs (e.g., EU auto OEM Tier 1) | Select SMBG13A-E3/52 only if halogen content is not regulated in target market or application. |
| SMBG13AHM3/52 | AEC-Q101 qualified + halogen-free (HM3 suffix); identical VWM, VBR, VC, PPPM | Includes automotive qualification beyond standard M3; validated for extended temperature cycling and HTGB | Choose SMBG13AHM3/52 when full AEC-Q101 validation documentation is contractually required for automotive production. |
Compared with SMBG13A-M3/52, SMBG13A-E3/52 offers identical protection performance but lacks halogen-free status, while SMBG13AHM3/52 adds formal AEC-Q101 certification - making the M3 variant the optimal balance of automotive readiness, environmental compliance, and cost for Tier 2 suppliers and industrial designs.

FAQ
What is the clamping voltage of SMBG13A-M3/52 and how is it measured?
The SMBG13A-M3/52 has a maximum clamping voltage (VC) of 21.5 V at 27.9 A peak pulse current (IPPM), tested with a 10/1000 µs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during standardized surge events, directly verified per Vishay Document Number 88456, page 2.
Is SMBG13A-M3/52 suitable for automotive applications?
Yes, SMBG13A-M3/52 is AEC-Q101 qualified and rated for -55 °C to +150 °C operation, making it suitable for under-hood and body electronics. Its halogen-free (M3) construction and 600 W surge capability align with ISO 7637-2 and ISO 16750-2 requirements - confirmed in Vishay's qualification report referenced in Document 88456, page 3.
What does the "M3" suffix mean in SMBG13A-M3/52?
The "M3" suffix in SMBG13A-M3/52 indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, and industrial-grade qualification. It distinguishes this variant from E3 (RoHS only) and HM3 (AEC-Q101 + halogen-free), as defined in the Vishay ordering information table on page 3 of Document 88456.
How does SMBG13A-M3/52 differ from bidirectional variants like SMBG13CA?
SMBG13A-M3/52 is unidirectional with cathode marking and conducts only in reverse bias above VBR; SMBG13CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Electrical specs (VWM, VBR, VC) differ - SMBG13CA has VWM = 13 V but VBR = 14.4–15.9 V in both directions, per Table on page 2 of Document 88456.
What PCB pad layout is recommended for SMBG13A-M3/52 to achieve rated 600 W performance?
Vishay specifies mounting SMBG13A-M3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve full 600 W peak pulse power rating. Smaller pads reduce thermal dissipation and derate power handling - details are provided in the "Maximum Ratings" section and Fig. 1 notes on page 1 of Document 88456.
