Product details
Overview
P6SMB68CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power with 10/1000 μs waveform, 68 V breakdown voltage (VBR min/max = 64.6–71.4 V at 1 mA), and clamping voltage of 92.0 V at 6.5 A peak pulse current. It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules against ESD and inductive switching transients.
For engineers reviewing the P6SMB68CA-M3/52 datasheet, P6SMB68CA-M3/52 pinout, P6SMB68CA-M3/52 application, or P6SMB68CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, 92.0 V max clamping voltage at rated IPPM, halogen-free RoHS-compliant M3 suffix, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its CA (bidirectional) suffix, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at 58.1 V stand-off), while meeting MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device delivers 600 W transient suppression under repetitive 0.01% duty cycle conditions, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = 150 °C in compact PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V at 1 mA - defines precise voltage threshold where clamping initiates with ±5% tolerance |
| VWM | 58.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 92.0 V at 6.5 A - clamped voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient power handling capacity under standardized 10/1000 μs waveform |
| Package | SMB (DO-214AA) - 3.94 mm × 2.20 mm footprint, compatible with standard SMT pick-and-place and reflow profiles |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix), MSL Level 1 - supports lead-free manufacturing and environmental requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse bias) | One terminal of bidirectional PN junction; accepts surge current in either direction |
| Cathode | Transient current exit (reverse bias) | Second terminal of bidirectional PN junction; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC, differential, or floating signal lines without polarity-sensitive layout constraints |
| 600 W peak pulse power | Withstands high-energy transients from inductive load switching or lightning-induced surges in industrial environments |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and low leakage across temperature and lifetime |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns, reducing manufacturing risk |
| Halogen-free M3 construction | Meets stringent environmental compliance (IEC 61249-2-21) while maintaining thermal and electrical performance |
Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN FD or LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in engine control units. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed directly at connector entry point to shunt transients before reaching interface ICs. Use Value: Limits voltage excursion to ≤92.0 V during 6.5 A surge, preserving integrity of 5 V or 3.3 V rail-powered sensors and transceivers. | Use Scenario: Safeguarding digital input/output channels on programmable logic controller (PLC) modules exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC I/O lines, coordinated with series impedance to meet IEC 61000-4-4 and -4-5 immunity requirements. Use Value: Absorbs 600 W transient energy without degradation, enabling >100,000 surge cycles per IEC 61000-4-5 Annex C test profile. |
| Telecom Line Card Surge Protection | Consumer USB/DisplayPort ESD Guard |
Use Scenario: Front-end protection for Ethernet PHYs and PoE injectors on telecom line cards subjected to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Secondary-level TVS paired with GDT or polymer PTC to handle residual energy after primary suppression stages. Use Value: Clamps differential surges to <92.0 V within <1 ns response time, preventing latch-up or gate oxide damage in 2.5 Gbps PHYs. | Use Scenario: Board-level ESD protection for high-speed consumer interfaces such as USB 3.2 Gen 2 or DisplayPort 1.4 connectors. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical at 0 V) bidirectional clamp placed adjacent to connector to minimize signal distortion. Use Value: Maintains signal integrity while passing IEC 61000-4-2 ±15 kV contact discharge, verified per AEC-Q101 stress protocols when used in automotive-grade variants. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ68CA | Same 68 V VBR, but 400 W PPPM and SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; less robust for industrial 24 V I/O or automotive load dump | Select when board space is constrained and surge energy remains below 400 W |
| 1.5KE68CA | Same 68 V VBR, 1500 W PPPM, axial DO-201 package - larger size, higher thermal mass | Requires through-hole assembly; better for high-repetition surges but incompatible with SMT-only lines | Select when legacy through-hole design or higher single-pulse energy absorption is required |
Compared with SMAJ68CA and 1.5KE68CA, P6SMB68CA-M3/52 offers optimal balance of 600 W surge capacity, SMB SMT compatibility, and halogen-free compliance-making it preferred for new automotive and industrial designs requiring automated assembly and environmental certification.

FAQ
What does the "CA" suffix indicate in P6SMB68CA-M3/52?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB68CA-M3/52 provides symmetrical clamping in both forward and reverse directions. This allows it to protect AC-coupled signals, differential buses like CAN or RS-485, and floating inputs without regard to polarity-unlike unidirectional "A" variants which require correct cathode orientation.
Is P6SMB68CA-M3/52 suitable for automotive applications?
Yes, P6SMB68CA-M3/52 meets commercial-grade specifications and is part of the AEC-Q101-qualified P6SMB family (with HE3/HM3 suffixes). While the M3 suffix itself is not AEC-Q101 certified, its construction-glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max-supports automotive under-hood and body-control module use when qualified per system-level testing per ISO 16750 and ISO 7637-2.
What is the maximum clamping voltage of P6SMB68CA-M3/52 under surge conditions?
The maximum clamping voltage of P6SMB68CA-M3/52 is 92.0 V at 6.5 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream 3.3 V or 5 V ICs remain within safe operating limits during transient events.
How does the M3 suffix differ from E3 in P6SMB68CA-M3/52?
The M3 suffix in P6SMB68CA-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance, whereas E3 denotes standard RoHS compliance without halogen-free assurance. Both share identical electrical specs and SMB packaging, but M3 satisfies stricter environmental mandates such as IEC 61249-2-21 for halogen content.
Can P6SMB68CA-M3/52 be used in place of P6SMB68A-M3/52?
No-P6SMB68CA-M3/52 is bidirectional, while P6SMB68A-M3/52 is unidirectional. Substituting them requires verifying circuit topology: P6SMB68CA-M3/52 works on AC, differential, or polarity-agnostic lines; P6SMB68A-M3/52 must be oriented with cathode toward the protected rail. Using the wrong variant risks incomplete protection or forward conduction during normal operation.
