Product details
Overview
P6SMB200CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 200 V standoff voltage (VWM), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 µs waveform - deployed in industrial motor drives, automotive sensor interfaces, and telecom power rails.
For engineers reviewing the P6SMB200CA-M3/5B datasheet, P6SMB200CA-M3/5B pinout, P6SMB200CA-M3/5B application, or P6SMB200CA-M3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (M3 suffix), and SMB (DO-214AA) package compatibility with automated SMT assembly.
Technical Context
This device operates as a voltage-clamped shunt protector: under transient overvoltage conditions exceeding its breakdown threshold (VBR = 234–246 V), it rapidly switches to low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional structure enables symmetric clamping in AC-coupled or floating signal paths without polarity constraints.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and TJ(max) = +150 °C, supporting operation in high-temperature industrial environments. The glass-passivated junction ensures stable leakage (<1 µA at VWM) and long-term reliability under repetitive transients at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe operating margin below system rail. |
| VBR (Breakdown) | 234–246 V at 1 mA - Verified voltage range where device transitions from high- to low-impedance state; ensures predictable turn-on timing. |
| VC (Clamping) | 274 V at IPPM = 2.2 A - Peak voltage seen across protected circuit during worst-case 10/1000 µs surge; determines stress on downstream components. |
| PPPM | 600 W - Peak transient power dissipation capability; supports protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) in properly laid out PCBs. |
| IPPM | 2.2 A - Maximum non-repetitive peak pulse current (10/1000 µs); sets minimum trace width and fuse coordination requirements. |
| TJ(max) | +150 °C - Maximum junction temperature; allows operation in under-hood automotive or enclosed industrial enclosures without derating below 100% rating. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with J-STD-020 MSL Level 1 reflow profiles (260 °C peak). |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are functionally symmetric; both leads serve as interchangeable surge-current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (bidirectional) | Accepts transient energy from either polarity; connects to line being protected (e.g., CAN_H, RS-485 A, DC bus+). |
| Cathode | Surge current entry (bidirectional) | Accepts transient energy from either polarity; connects to reference plane (GND or complementary line like CAN_L/RS-485 B). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (CAN, RS-485), or floating DC rails without external polarity management. |
| 600 W peak pulse power (10/1000 µs) | Provides immunity to high-energy transients per IEC 61000-4-5 Ed.3, supporting industrial-grade surge withstand without cascaded protection stages. |
| Glass-passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<1 µA), and resistance to humidity-induced parameter drift in harsh environments. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and EU Directive 2015/863; eliminates brominated flame retardants in molding compound. |
| MSL Level 1 (260 °C peak) | Permits standard lead-free reflow without baking or special handling; reduces manufacturing cost and process complexity. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM/VC, but lower PPPM = 400 W; SMA package (smaller thermal mass, higher RθJA = 140 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for 48 V PoE++ or automotive load-dump. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with layout simulation. |
| SMCJ200CA | Same VWM/VC, higher PPPM = 1500 W; larger SMC (DO-214AB) package with RθJA = 65 °C/W. | Supports higher-duty-cycle surges and repeated 10/1000 µs events; requires larger PCB area and higher solder volume. | Choose for mission-critical industrial controls or railway electronics where 1500 W headroom and extended thermal endurance are required. |
Compared with SMAJ200CA and SMCJ200CA, the P6SMB200CA-M3/5B delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, and halogen-free compliance - making it ideal for volume-manufactured automotive modules and telecom infrastructure where MSL Level 1 processing and RoHS traceability are mandatory.

FAQ
What is the clamping voltage of the P6SMB200CA-M3/5B under a 10/1000 µs surge?
The P6SMB200CA-M3/5B clamps to a maximum of 274 V when subjected to its rated peak pulse current of 2.2 A with a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees the protected circuit sees no more than 274 V during such transients - critical for safeguarding 30 V-rated downstream components. The P6SMB200CA-M3/5B achieves this with low incremental surge resistance and sub-nanosecond response.
Is the P6SMB200CA-M3/5B suitable for automotive applications?
The P6SMB200CA-M3/5B is halogen-free and RoHS-compliant but not AEC-Q101 qualified - its base ordering code lacks the HE3 or HM3 suffix required for automotive qualification. For automotive use, engineers must select P6SMB200CAHM3_B/I or equivalent AEC-Q101 variants. The P6SMB200CA-M3/5B remains appropriate for industrial and telecom applications where AEC-Q101 is not mandated.
What does the "CA" suffix indicate in P6SMB200CA-M3/5B?
The "CA" suffix in P6SMB200CA-M3/5B denotes a bidirectional Transient Voltage Suppressor configuration. Unlike unidirectional versions (e.g., P6SMB200A), the CA variant provides symmetrical clamping for both positive and negative voltage transients - essential for protecting AC-coupled lines, differential buses like CAN or RS-485, and floating DC rails without polarity concerns. The P6SMB200CA-M3/5B has no cathode band marking.
What is the maximum operating temperature for the P6SMB200CA-M3/5B?
The P6SMB200CA-M3/5B has a maximum junction temperature (TJ(max)) of +150 °C, enabling reliable operation in high-temperature environments such as under-hood automotive ECUs, industrial motor drive cabinets, and enclosed telecom power supplies. Its thermal resistance (RθJA = 100 °C/W) is specified for mounting on 0.2" × 0.2" copper pads - derating curves in the datasheet guide safe power handling above 25 °C ambient.
How does the M3 suffix affect the P6SMB200CA-M3/5B's compliance profile?
The "M3" suffix in P6SMB200CA-M3/5B indicates halogen-free, RoHS-compliant construction per EU Directive 2015/863, with brominated and chlorinated flame retardants eliminated from the epoxy molding compound. It meets IPC-1752A material declarations and JESD201 Class 2 whisker resistance. This distinguishes it from E3-suffix parts (RoHS-compliant but not halogen-free) and ensures compatibility with strict green manufacturing requirements. The P6SMB200CA-M3/5B retains full electrical equivalence to E3 variants.
