Product details
Overview
P6SMB6.8CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 600 W peak pulse power with a 10/1000 μs waveform, 6.8 V breakdown voltage (VBR), and 10.5 V maximum clamping voltage (VC) at 57.1 A peak pulse current - designed to protect sensitive signal lines and power rails in consumer, industrial, and automotive electronics.
For engineers reviewing the P6SMB6.8CA-M3/52 datasheet, P6SMB6.8CA-M3/52 pinout, P6SMB6.8CA-M3/52 application, or P6SMB6.8CA-M3/52 equivalent, this device delivers verified bidirectional surge suppression with halogen-free RoHS compliance, MSL Level 1 rating, and AEC-Q101 qualification readiness - critical for ESD and lightning transient protection in compact PCB layouts.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling robust protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5% min/max), low incremental surge resistance, and fast response time (<1 ns) to transients induced by inductive switching or ESD events.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), supporting reliable operation up to TJ = +150 °C. The device is rated for repetitive 0.01% duty cycle pulses and derates linearly above 25 °C ambient per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 5.80 V - maximum continuous reverse working voltage before leakage exceeds 1000 μA |
| VC @ IPPM | 10.5 V at 57.1 A - peak clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 μs waveform, validated for repetitive surge immunity |
| IPPM | 57.1 A - maximum non-repetitive peak pulse current supported under standard test conditions |
| TJ max. | +150 °C - maximum junction temperature enabling use in high-ambient industrial and under-hood automotive environments |
| Package | SMB (DO-214AA) - surface-mount outline with 0.220" × 0.130" footprint, compatible with automated placement and reflow |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetrical with cathode in bidirectional operation | Enables identical clamping behavior for positive and negative transients - no orientation required during placement |
| Cathode | Current exit terminal in forward bias; electrically equivalent to anode in bidirectional mode | Eliminates need for polarity-aware routing or silkscreen marking - simplifies layout and reduces BOM variants |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 600 W surge rating | Protects AC-coupled interfaces (e.g., RS-485, CAN, USB D+/D−) without external polarity management |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for global industrial and automotive production without material waivers |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without moisture sensitivity concerns or baking preconditioning |
| Low clamping ratio (VC/VBR ≈ 1.55) | Minimizes voltage overshoot during transients - critical for protecting 3.3 V or 5 V logic-level components |
| AEC-Q101 qualification path | Base ordering code HM3_X enables automotive-grade sourcing; P6SMB6.8CA-M3/52 shares same die and process as qualified variants |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8CA | Same VBR (6.45–7.14 V), lower PPPM = 400 W, SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for industrial load-switching events requiring 600 W margin | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin at full load. |
| 1.5KE6.8CA | Same VBR, higher PPPM = 1500 W, axial DO-201 package (through-hole, larger footprint) | Requires through-hole assembly; incompatible with fully SMT designs and automated pick-and-place | Choose only for legacy through-hole systems or where 1500 W headroom justifies manual assembly cost and board real estate. |
Compared with SMAJ6.8CA and 1.5KE6.8CA, P6SMB6.8CA-M3/52 delivers optimal balance of 600 W surge capacity, SMB surface-mount compatibility, and halogen-free compliance - making it the preferred choice for new SMT-based industrial and automotive designs requiring certified environmental and reliability attributes.

FAQ
What is the clamping voltage of P6SMB6.8CA-M3/52 at its rated peak pulse current?
The P6SMB6.8CA-M3/52 has a maximum clamping voltage (VC) of 10.5 V at its rated peak pulse current (IPPM) of 57.1 A, measured under the standard 10/1000 μs waveform condition. This value ensures downstream components operating at 3.3 V or 5 V logic levels remain within safe voltage margins during surge events. The clamping performance is guaranteed across the full operating temperature range from −65 °C to +150 °C.
Is P6SMB6.8CA-M3/52 suitable for automotive applications?
Yes, P6SMB6.8CA-M3/52 is built on the same die and process as AEC-Q101-qualified variants (e.g., P6SMB6.8CAHM3_B/H). While the M3 suffix itself denotes halogen-free RoHS compliance, the base P6SMB6.8CA-M3/52 shares identical electrical, thermal, and mechanical characteristics with qualified versions - enabling direct qualification path for automotive body electronics and infotainment interfaces.
Does P6SMB6.8CA-M3/52 require polarity-aware PCB layout?
No, P6SMB6.8CA-M3/52 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode band or polarity marking on the SMB package, eliminating orientation constraints during placement. This simplifies PCB design, reduces assembly errors, and supports automated optical inspection without polarity validation steps.
What is the maximum steady-state power dissipation for P6SMB6.8CA-M3/52?
The P6SMB6.8CA-M3/52 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C. Under typical PCB conditions (0.2" × 0.2" copper pads per terminal), derating applies above 25 °C ambient per Figure 2 in the datasheet. For continuous DC or low-frequency operation, ensure average power remains well below this limit to avoid thermal runaway.
How does the M3 suffix affect the environmental compliance of P6SMB6.8CA-M3/52?
The M3 suffix on P6SMB6.8CA-M3/52 indicates halogen-free, RoHS-compliant construction per JEDEC standards, with no brominated flame retardants or chlorine-based compounds in the molding compound or plating. This meets stringent environmental requirements for export to EU, China, and other regulated markets, and supports end-of-life recycling without hazardous emissions during PCB rework or disposal.
