Product details
Overview
SMBG10CA-M3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of signal and power lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), 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 SMBG10CA-M3/5B datasheet, SMBG10CA-M3/5B pinout, SMBG10CA-M3/5B application, or SMBG10CA-M3/5B equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, halogen-free RoHS compliance (M3 suffix), 150 °C junction temperature rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction characteristics due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching transients before IC damage occurs.
The SMBG10CA-M3/5B delivers consistent clamping performance across -55 °C to +150 °C ambient, supported by thermal resistance values of RθJA = 100 °C/W and RθJL = 20 °C/W. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance, confirming suitability for high-reliability automotive and industrial deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working margin for 12 V nominal systems. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Confirmed breakdown threshold ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamping voltage under full 600 W surge limits downstream IC stress to safe levels per IEC 61000-4-5. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform supports repetitive surge events at 0.01% duty cycle. |
| TJ max. | +150 °C - Extended junction temperature rating enables use in under-hood automotive environments and sealed industrial enclosures. |
| Package | SMBG (DO-215AA) - Surface-mount outline with 0.235" × 0.255" footprint, optimized for automated pick-and-place and reflow compatibility. |

IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp transients before reaching PHY layer. Use Value: 17.0 V clamping voltage ensures microcontroller GPIOs and transceiver inputs remain below absolute maximum ratings during 12 V system surges. | Use Scenario: Shielding PLC digital input cards and RS-485 transceivers from field-induced lightning surges and relay coil kickback in factory automation. IC Role / Device Role / Timing Role: Primary line-level surge suppressor mounted adjacent to terminal blocks or connectors on PCB edge. Use Value: 600 W rating sustains repeated 10/1000 μs transients up to 35.3 A without degradation, extending field unit MTBF. |
| Consumer Power Adapter Input | Telecom Line Card Protection |
Use Scenario: Safeguarding AC-DC adapter primary-side rectifier and controller ICs against mains-borne surges and capacitor discharge events. IC Role / Device Role / Timing Role: Secondary-stage TVS after MOV, providing precise low-voltage clamping for sensitive SMPS controllers. Use Value: 10 V VWM allows integration with 12 V auxiliary rails while maintaining >2 V margin above nominal, preventing leakage-induced heating. | Use Scenario: Protecting Ethernet PHYs and PoE injectors from induced surges on twisted-pair cabling in enterprise switch line cards. IC Role / Device Role / Timing Role: Differential-mode suppressor across data pairs (e.g., TX+/TX−) to preserve signal integrity during surge events. Use Value: Symmetrical bidirectional response maintains common-mode rejection ratio (CMRR) and avoids DC bias shift on differential lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-T | Same VWM/VBR/VC specs but SMB (DO-214AA) package; 10% larger footprint and higher RθJA (125 °C/W). | Limited to non-AEC-Q101 industrial use; not qualified for automotive under-hood mounting. | Select when board space permits larger package and AEC-Q101 is not required. |
| 1.5KE10CA | Through-hole TO-218 package; same electrical specs but 1500 W rating and slower thermal response. | Used in legacy power supplies and high-energy surge panels where SMT is impractical. | Choose only for through-hole assembly or where higher single-pulse energy absorption is mandatory. |
Compared with SMBJ10CA-T and 1.5KE10CA, the SMBG10CA-M3/5B offers superior thermal performance (RθJL = 20 °C/W), AEC-Q101 qualification, and compact SMBG footprint - making it optimal for space-constrained, high-reliability automotive and industrial SMT designs requiring verified long-term surge endurance.

FAQ
What is the clamping voltage of SMBG10CA-M3/5B at its rated peak pulse current?
The SMBG10CA-M3/5B has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured using a 10/1000 μs waveform. This value ensures protected circuits remain within safe operating limits during standardized surge events defined in IEC 61000-4-5. The SMBG10CA-M3/5B achieves this with low incremental surge resistance and symmetrical bidirectional response.
Is SMBG10CA-M3/5B suitable for automotive applications?
Yes, SMBG10CA-M3/5B is AEC-Q101 qualified and rated for operation from -55 °C to +150 °C, making it suitable for automotive applications including engine control units, ADAS sensor interfaces, and body electronics. Its halogen-free (M3) and RoHS-compliant construction meets stringent automotive supply chain requirements. The SMBG10CA-M3/5B also carries UL 497B recognition for surge protector classification.
What does the "M3" suffix indicate in SMBG10CA-M3/5B?
The "M3" suffix in SMBG10CA-M3/5B denotes halogen-free, RoHS-compliant construction with industrial-grade reliability and JESD201 Class 2 whisker resistance. It distinguishes this variant from "E3" (standard RoHS) and "HM3" (AEC-Q101 + halogen-free). The M3 designation confirms compliance with JEDEC JS709E and environmental mandates for global automotive and industrial markets. SMBG10CA-M3/5B is fully traceable and qualified for high-volume SMT production.
How does SMBG10CA-M3/5B differ from unidirectional TVS diodes like SMBG10A-M3/5B?
SMBG10CA-M3/5B is bidirectional, providing identical clamping behavior in both forward and reverse directions, whereas SMBG10A-M3/5B is unidirectional with cathode marking and conducts only in reverse bias. This makes SMBG10CA-M3/5B ideal for AC-coupled, differential, or floating signal lines (e.g., CAN, RS-485), while SMBG10A-M3/5B suits DC power rail protection. Both share the same SMBG package, VWM, and PPPM rating, but SMBG10CA-M3/5B has no polarity band.
What is the thermal resistance specification for SMBG10CA-M3/5B?
The SMBG10CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. These values enable effective heat dissipation during repetitive surge events and support reliable operation at TJ = 150 °C. Proper PCB copper pour design is essential to maintain these thermal performance metrics in actual SMBG10CA-M3/5B deployments.
