Overview
P6SMB10CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 41.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB10CA-M3/5B datasheet, P6SMB10CA-M3/5B pinout, P6SMB10CA-M3/5B application, or P6SMB10CA-M3/5B equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, SMB package thermal and mechanical data, and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (88370, Rev. 09-Jan-2024).
Technical Context
The P6SMB10CA-M3/5B operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its breakdown voltage (VBR) is specified at 9.5–10.5 V with 1 mA test current, and it maintains low incremental surge resistance to ensure stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C. The device uses glass-passivated junction technology and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for protected circuitry. |
| VBR (Breakdown) | 9.5–10.5 V at IT = 1 mA - Ensures predictable, repeatable avalanche initiation across production lots. |
| VC (Clamping) | 14.5 V at IPPM = 41.4 A - Limits transient voltage seen by downstream components during 10/1000 μs surge events. |
| PPPM | 600 W - Peak pulse power handling capacity with standardized 10/1000 μs waveform; critical for lightning/ESD immunity design. |
| IPPM | 41.4 A - Peak pulse current corresponding to VC; determines minimum trace width and PCB copper pad sizing. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.130" footprint; optimized for automated placement and thermal dissipation on 5.0 mm × 5.0 mm copper pads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same SMB package, identical VWM (10 V) and VC (14.5 V), but rated for 600 W with tighter VBR tolerance (9.5–10.3 V vs. 9.5–10.5 V). | Preferred where tighter breakdown consistency is required for precision clamping thresholds. | Select SMBJ10CA when statistical process control demands narrower VBR distribution across production lots. |
| 1.5SMC10CA | Larger SMC (DO-214AB) package; same electrical specs but higher thermal mass (RθJA = 50 °C/W vs. 100 °C/W) and 1.5 kW peak power rating. | Suitable for high-energy surge environments where PCB space allows larger footprint and enhanced heat dissipation is needed. | Choose 1.5SMC10CA only if board layout permits SMC footprint and system-level surge testing exceeds 600 W requirements. |
Compared with SMBJ10CA and 1.5SMC10CA, the P6SMB10CA-M3/5B offers optimal balance of compact SMB size, halogen-free compliance, and verified 600 W performance - making it ideal for space-constrained industrial and automotive modules where consistent clamping and RoHS/Material Compliance are mandatory.

FAQ
What is the clamping voltage of the P6SMB10CA-M3/5B at its rated peak pulse current?
The P6SMB10CA-M3/5B has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and reflects the actual voltage imposed on protected circuitry during worst-case transient events - a key parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is the P6SMB10CA-M3/5B suitable for automotive applications?
Yes, the P6SMB10CA-M3/5B is halogen-free and RoHS-compliant, and the P6SMB10CA-M3/5B family includes AEC-Q101-qualified variants (e.g., P6SMB10CAHM3_B). While the exact -M3/5B suffix denotes commercial-grade packaging, its construction - glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max - aligns with automotive under-hood and body-control module requirements when paired with appropriate system-level validation.
How does the bidirectional design of the P6SMB10CA-M3/5B affect PCB layout?
The P6SMB10CA-M3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout, reduces assembly errors, and enables direct integration into AC-coupled or differential signal paths - such as RS-485 or CAN bus lines - without requiring additional diode pairing or directional verification.
What is the thermal resistance of the P6SMB10CA-M3/5B, and how does it impact board design?
The P6SMB10CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides minimum copper area requirements: reducing pad size increases thermal impedance, potentially causing premature thermal runaway during repetitive surges - so adherence to Vishay's recommended layout is essential for sustained 600 W performance.
Does the P6SMB10CA-M3/5B meet industry surge immunity standards like IEC 61000-4-5?
Yes, the P6SMB10CA-M3/5B's 600 W peak pulse power rating with a 10/1000 μs waveform directly supports compliance with IEC 61000-4-5 level 3 (1 kV line-earth, 2 kV line-line) when implemented with proper PCB layout - including short traces, adequate ground plane coupling, and minimal loop area. Its low clamping voltage (14.5 V) ensures protected circuits remain within safe operating limits during standardized surge testing.
