Product details
Overview
P6SMB200CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB200CA-E3/52 datasheet, P6SMB200CA-E3/52 pinout, P6SMB200CA-E3/52 application, or P6SMB200CA-E3/52 equivalent, key selection considerations include bidirectional clamping symmetry, SMB (DO-214AA) package thermal performance, junction temperature derating above 25 °C, and compliance with AEC-Q101 when ordered with HE3/HM3 suffixes.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR (220–242 V), VC (274 V), and IPPM (2.2 A) specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device uses a low-inductance SMB (DO-214AA) package with matte tin-plated leads, rated for MSL level 1 reflow (peak 260 °C), and achieves thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads - critical for sustained transient energy dissipation without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown Voltage) | 220–242 V at 1 mA test current - Voltage at which device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping Voltage) | 274 V at 2.2 A IPPM - Peak voltage seen by downstream circuit during worst-case 10/1000 μs transient; determines protection margin. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorbed per event (10/1000 μs waveform); defines single-event surge robustness. |
| ID (Reverse Leakage) | <1.0 μA at 200 V - Minimal standby current draw; avoids loading sensitive analog or low-power circuits. |
| TJ max. | +150 °C - Maximum junction temperature; sets upper limit for ambient + power dissipation design margin. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard PCB pad layout; guides heatsinking requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - symmetrical anode/cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse polarity) | Accepts positive-going surges relative to cathode; forms one half of bidirectional clamping path. |
| Cathode | Transient current entry (forward polarity) | Accepts negative-going surges relative to anode; completes symmetrical clamping behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates need for polarity-aware placement in AC-coupled or floating lines. |
| Glass passivated junction | Stable leakage <1 μA and consistent VBR over lifetime - ensures long-term reliability in harsh environments. |
| 600 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 (4 kV) surges when properly mounted - meets industrial and automotive surge immunity standards. |
| MSL Level 1 moisture sensitivity | Reflow-compatible up to 260 °C peak - supports standard SMT assembly without baking or special handling. |
| AEC-Q101 qualification option | Available with HE3/HM3 suffixes - validated for automotive under-hood and body electronics applications. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VC tolerance (±5 % vs. ±10 % typical for P6SMB series). | Preferred where tighter clamping consistency is required across production lots, e.g., medical-grade isolation barriers. | Select SMBJ200CA if tighter VC distribution and lower RθJA (85 °C/W) are needed for higher ambient temperature operation. |
| 1.5SMC200CA | Larger SMC (DO-214AB) package, same electrical specs, higher thermal mass (RθJA = 60 °C/W), 1.5 kW peak pulse rating. | Suitable for high-repetition-rate surges or systems requiring extended surge endurance beyond single-event rating. | Choose 1.5SMC200CA when board space allows and system-level testing demands >600 W margin or multi-pulse robustness. |
Compared with SMBJ200CA and 1.5SMC200CA, P6SMB200CA-E3/52 offers optimal cost and footprint for single-event surge protection in space-constrained consumer and industrial designs, balancing clamping precision, thermal performance, and manufacturability in standard SMB layouts.

FAQ
What is the clamping voltage of P6SMB200CA-E3/52 at its rated peak pulse current?
The P6SMB200CA-E3/52 has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value represents the highest voltage imposed on protected circuitry during a worst-case transient event, and it is guaranteed per Vishay's datasheet revision 09-Jan-2024. The P6SMB200CA-E3/52 maintains this clamping performance bidirectionally due to its symmetrical construction.
Is P6SMB200CA-E3/52 suitable for automotive applications?
P6SMB200CA-E3/52 itself is commercial-grade (RoHS-compliant, E3 suffix), but Vishay offers AEC-Q101 qualified versions under ordering codes like P6SMB200CAHE3_B. The P6SMB200CA-E3/52 shares identical electrical and thermal characteristics with those qualified variants - only the qualification testing and traceability differ. For non-safety-critical automotive subsystems (e.g., infotainment sensors), P6SMB200CA-E3/52 is widely deployed, though formal AEC-Q101 certification requires the HE3/HM3 suffix.
What is the thermal resistance of P6SMB200CA-E3/52, and how does it affect PCB layout?
The P6SMB200CA-E3/52 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 means each watt of steady-state power raises junction temperature by 100 °C above ambient - but since P6SMB200CA-E3/52 is rated for transient (not continuous) power, layout focuses on minimizing thermal impedance during pulse events. Adequate copper area and optional thermal vias directly under the SMB pads improve heat spreading and prevent localized overheating during repetitive surges.
How does the bidirectional nature of P6SMB200CA-E3/52 impact its use in DC circuits?
The bidirectional design of P6SMB200CA-E3/52 allows it to protect both positive and negative voltage excursions symmetrically - making it ideal for AC-coupled lines, floating references, or DC circuits subject to reverse polarity faults. In a 24 V DC system, for example, P6SMB200CA-E3/52 clamps both +274 V surges (relative to ground) and −274 V transients (ground rising above line), unlike unidirectional TVS diodes that would require external biasing or dual-device configurations. This simplifies design and reduces BOM count.
What is the maximum reverse leakage current of P6SMB200CA-E3/52 at its standoff voltage?
The P6SMB200CA-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 200 V standoff voltage (VWM), tested at TA = 25 °C. This ultra-low leakage ensures minimal power loss and avoids interference with high-impedance sensor inputs or battery-powered circuits. Leakage remains below 5 μA even at 125 °C junction temperature, supporting reliable operation in industrial and automotive under-hood environments where the P6SMB200CA-E3/52 is commonly applied.
