Product details
Overview
P6SMB200CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 274 V at 2.2 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB200CAHM3_B/I datasheet, P6SMB200CAHM3_B/I pinout, P6SMB200CAHM3_B/I application, or P6SMB200CAHM3_B/I equivalent, this device serves as a robust, low-profile surge protector for bidirectional signal lines, power rails, and sensor interfaces where high clamping ratio, fast response (<1 ns), and automotive-grade reliability are required.
Technical Context
The P6SMB200CAHM3_B/I operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 171 V), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
Designed for repetitive surge suppression under 0.01% duty cycle, it delivers 600 W peak pulse power with 10/1000 μs waveform, exhibits 20 °C/W junction-to-lead thermal resistance, and maintains clamping performance across -65 °C to +150 °C operating junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 24–48 V DC systems. |
| VBR (Breakdown Voltage) | 220 V min - Avalanche conduction begins at ≥220 V, ensuring reliable triggering above system overvoltage thresholds. |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs transient; enables downstream IC survival with >25 V headroom. |
| PPPM (Peak Pulse Power) | 600 W - Sustains standardized lightning/surge energy per IEC 61000-4-5; validated with 0.01% duty cycle derating. |
| ID (Reverse Leakage) | ≤1.0 μA at 200 V - Negligible standby current; avoids loading sensitive analog or low-power sensor circuits. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal shutdown. |
| Package | SMB (DO-214AA) - Surface-mount footprint (5.59 mm × 4.06 mm) compatible with automated placement; meets UL 94 V-0 flammability. |
Pinout & Package
SMB (DO-214AA) package: bidirectional device with no polarity marking; symmetrical two-terminal construction. Cathode/anode designation does not apply - terminals are functionally identical for AC or dual-polarity DC protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal connects to protected line; no polarity dependency - enables flexible PCB layout on differential or AC-coupled paths. |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completes clamping path to ground or rail; symmetric structure eliminates orientation constraints during assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensors - guarantees reliability under thermal cycling, vibration, and humidity stress. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20; supports green manufacturing and end-of-life compliance without compromising surge robustness. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly laid out - reduces need for secondary protection stages. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), critical for protecting high-speed CAN, LIN, and sensor interfaces. |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT processes without pre-baking; eliminates moisture-related popcorning risk during assembly. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

| Telecom Power Rail Protection | Consumer Appliance Motor Control |
|
Use Scenario: Clamping transients on 48 V PoE-powered Ethernet switch ports subjected to lightning-induced surges on data pairs and auxiliary power lines. IC Role / Device Role / Timing Role: Bidirectional TVS placed at port entry point, referenced to common-mode ground, limiting differential and common-mode overvoltages simultaneously. Use Value: 200 V VWM allows compatibility with IEEE 802.3bt Class 5/6 PoE, while 274 V VC ensures PHY ICs remain within absolute maximum ratings during surge events. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines) driving microcontroller-based motor drivers. IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge supply rails to clamp inductive flyback energy before it couples into logic supply domains. Use Value: Halogen-free construction meets IEC 62368-1 flame retardancy requirements, while 150 °C TJ max supports sealed, thermally constrained motor housings. |
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/VBR/VC specs but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only if space-constrained and surge energy is ≤400 W; verify thermal margin with board copper area. |
| 1.5KE200CA | Higher PPPM (1500 W) but axial-leaded DO-201 package; slower response due to lead inductance; not surface-mount. | Requires through-hole assembly; incompatible with automated SMT lines; less effective for fast ESD. | Choose only for legacy through-hole designs or where 1.5 kW surge handling outweighs SMT compatibility and speed. |
Compared with SMAJ200CA and 1.5KE200CA, the P6SMB200CAHM3_B/I uniquely balances 600 W surge capability, SMB SMT compatibility, AEC-Q101 qualification, and halogen-free compliance - making it the optimal choice for new automotive and industrial designs requiring production-ready, high-reliability TVS protection.

FAQ
What is the clamping voltage of P6SMB200CAHM3_B/I at its rated peak pulse current?
The P6SMB200CAHM3_B/I clamps to a maximum of 274 V at its specified peak pulse current of 2.2 A under the 10/1000 μs waveform condition. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is P6SMB200CAHM3_B/I suitable for automotive applications?
Yes, P6SMB200CAHM3_B/I is AEC-Q101 qualified (indicated by the "HM3_B" suffix), halogen-free, and RoHS-compliant. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and ESD per automotive requirements - making it approved for use in engine control units, body electronics, and ADAS sensor modules where reliability under harsh conditions is mandatory.
How does the bidirectional configuration of P6SMB200CAHM3_B/I affect PCB layout?
The P6SMB200CAHM3_B/I has no polarity marking and functions identically in both directions, so PCB layout requires no orientation alignment. Engineers can place it symmetrically across differential signal pairs (e.g., CAN_H/CAN_L) or AC-coupled lines without concern for anode/cathode assignment - reducing design complexity and eliminating assembly errors.
What is the maximum operating junction temperature for P6SMB200CAHM3_B/I?
The P6SMB200CAHM3_B/I has a maximum junction temperature (TJ max) of +150 °C, verified per Vishay's thermal characterization. This rating supports continuous operation in under-hood automotive environments and enclosed industrial enclosures, provided PCB copper pad area meets the 0.2" × 0.2" (5.0 mm × 5.0 mm) minimum recommendation for thermal dissipation.
Does P6SMB200CAHM3_B/I meet UL 94 flammability requirements?
Yes, the P6SMB200CAHM3_B/I uses a molding compound certified to UL 94 V-0 flammability rating, as stated in the Mechanical Data section of Vishay document 88370. This ensures self-extinguishing behavior in fire scenarios - a mandatory requirement for safety-critical applications in industrial automation and consumer white goods.
