Product details
Overview
P6SMB200CA-M3/52 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 operates across -65 °C to +150 °C junction temperature - deployed for ESD and surge protection on automotive sensor signal lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the P6SMB200CA-M3/52 datasheet, P6SMB200CA-M3/52 pinout, P6SMB200CA-M3/52 application, or P6SMB200CA-M3/52 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), halogen-free RoHS compliance (M3 suffix), and direct replacement guidance against industry-standard TVS diodes used in board-level transient suppression.
Technical Context
The P6SMB200CA-M3/52 implements a silicon avalanche junction structure with glass passivation, enabling sub-nanosecond response to voltage transients and low incremental surge resistance. Its bidirectional configuration provides symmetrical clamping in both polarities without polarity marking, supporting AC-coupled or floating signal paths.
Designed for surface-mount reflow assembly, it meets J-STD-020 MSL Level 1 (260 °C peak), features matte tin-plated leads, and sustains 100 A non-repetitive forward surge current (IFSM) - critical for handling inductive kickback in relay or solenoid drive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 220 V min - Avalanche conduction initiates at this voltage under 1 mA test current; ensures predictable turn-on threshold. |
| VC (Clamping) | 274 V max at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe IC stress level. |
| PPPM | 600 W - Sustains single 10/1000 μs transient energy without failure; enables robust protection against lightning-induced surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
| TJ max | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive or enclosed industrial enclosures. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant (M3 suffix), 0.220" × 0.130" footprint with cathode band omitted (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Accepts reverse surge current during negative half-cycle; connects to protected line or ground reference. |
| Cathode | Transient current entry (positive polarity) | Accepts reverse surge current during positive half-cycle; symmetric role to Anode in bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating differential signals (e.g., RS-485, CAN bus) without polarity constraints. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) on 2 Ω source impedance when properly laid out. |
| Low clamping ratio (VC/VBR ≈ 1.25) | Minimizes overvoltage stress on downstream ICs - critical for 3.3 V or 5 V logic interfacing with 200 V-rated lines. |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns; eliminates bake-out requirement. |
Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA-T | Same VWM (200 V), identical SMB package, but rated for 600 W with 10/1000 μs waveform and RθJA = 100 °C/W - matches P6SMB200CA-M3/52 electrically and thermally. | No AEC-Q101 qualification; commercial-grade only - unsuitable for automotive under-hood use where P6SMB200CA-M3/52's M3 suffix ensures halogen-free compliance. | Select SMBJ200CA-T for cost-sensitive industrial designs where automotive qualification is not required. |
| 1.5KE200CA | Through-hole DO-15 package, same 200 V VWM and bidirectional function, but higher RθJA (~50 °C/W on larger pads) and lower surge robustness (1500 W peak, but 1.5 kW rating uses different waveform definition). | Requires PCB through-hole layout and wave soldering - incompatible with fully SMT production; larger footprint limits high-density routing. | Choose 1.5KE200CA only for legacy through-hole systems or prototyping where manual assembly is acceptable. |
Compared with SMBJ200CA-T and 1.5KE200CA, the P6SMB200CA-M3/52 uniquely combines halogen-free RoHS compliance, MSL Level 1 reflow readiness, and AEC-Q101 qualification eligibility - making it the preferred choice for automotive-grade SMT production where supply chain traceability and thermal reliability are mandatory.

FAQ
What is the clamping voltage of P6SMB200CA-M3/52 at its rated peak pulse current?
The P6SMB200CA-M3/52 has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM), measured using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The P6SMB200CA-M3/52 maintains this clamping performance across its full operating temperature range.
Is P6SMB200CA-M3/52 suitable for automotive applications?
Yes, the P6SMB200CA-M3/52 is halogen-free and RoHS-compliant (M3 suffix), and the base P6SMB200CA family supports AEC-Q101 qualification via HE3/HM3 variants. While the -M3/52 variant itself is commercial-grade, its construction - including glass-passivated junction, MSL Level 1 rating, and -65 °C to +150 °C operating range - aligns with automotive under-hood environmental requirements. For certified AEC-Q101 use, specify P6SMB200CAHM3_B/H or equivalent.
How does the bidirectional design of P6SMB200CA-M3/52 affect its PCB layout?
The P6SMB200CA-M3/52 has no polarity marking and functions identically in both directions, eliminating orientation constraints during automated placement. Layout requires symmetric 0.2" × 0.2" copper pads per terminal (per Vishay recommended footprint), low-inductance grounding to chassis or system ground, and placement within 2 mm of the protected connector or IC pin. No cathode/anode routing distinction is needed - simplifying layout and reducing assembly errors.
What is the thermal resistance of P6SMB200CA-M3/52, and how does it impact power derating?
The P6SMB200CA-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. At 25 °C ambient, it can dissipate up to 5.0 W continuously; above that temperature, power must be linearly derated - e.g., at 75 °C ambient, maximum continuous power drops to 2.5 W. This derating curve is documented in Figure 2 of the Vishay datasheet (document 88370).
Can P6SMB200CA-M3/52 replace unidirectional TVS diodes in existing designs?
No - the P6SMB200CA-M3/52 is strictly bidirectional and lacks polarity marking, so it cannot substitute for unidirectional TVS diodes (e.g., P6SMB200A-M3/52) in DC-biased circuits where reverse leakage or forward conduction matters. In AC or floating applications (e.g., RS-485, CAN), it offers functional equivalence; however, replacing a unidirectional part requires verifying signal path symmetry, ground referencing, and absence of DC bias across the TVS terminals.
