Product details
Overview
P6SMB27CA-E3/52 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 or power lines. It features a 23.1 V standoff voltage (VWM), 27 V nominal breakdown voltage (VBR at 1 mA), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB27CA-E3/52 datasheet, P6SMB27CA-E3/52 pinout, P6SMB27CA-E3/52 application, or P6SMB27CA-E3/52 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, RoHS-compliant commercial-grade construction, and AEC-Q101-qualified alternatives - all critical for surge protection design validation and BOM selection.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad layout (0.2" × 0.2") for sustained 5.0 W power dissipation.
The P6SMB27CA-E3/52 delivers fast response time (<1.0 ns), low incremental surge resistance, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is rated for -65 °C to +150 °C operating junction temperature and supports repetitive 0.01% duty cycle surges under defined thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 23.1 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 25.7–28.4 V at 1.0 mA - Verified avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 37.5 V at 16.0 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; determines downstream component stress. |
| PPPM | 600 W - Peak transient energy absorption capability; enables protection against IEC 61000-4-5 Level 4 surges when properly mounted. |
| IPPM | 16.0 A - Maximum non-repetitive surge current supported; defines minimum trace width and fuse coordination requirements. |
| TJ max. | +150 °C - Maximum junction temperature; constrains ambient operating range and heatsinking needs in sealed enclosures. |
| RθJA | 100 °C/W - Thermal resistance without heatsink; mandates ≥5.0 mm × 5.0 mm copper pads per terminal for rated power handling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One of two symmetrical terminals; connects to line being protected - no directional bias required for bidirectional operation. |
| Cathode | Transient current entry (positive polarity) | Second symmetrical terminal; identical to Anode in function; enables clamping of both positive and negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns or external circuitry. |
| 600 W peak pulse power | Supports robust immunity to lightning-induced surges (IEC 61000-4-5) and inductive switching spikes in motor drives and power supplies. |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime - critical for high-reliability industrial systems. |
| MSL Level 1 rating | Allows standard SMT reflow without moisture sensitivity precautions - simplifies manufacturing and reduces assembly cost. |
| RoHS-compliant, matte tin plating | Meets J-STD-002 and JESD 22-B102 solderability standards; supports lead-free assembly and eliminates whisker risk (JESD 201 Class 2). |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module (BCM) Power Line |

IC Role / Device Role / Timing Role: Bidirectional TVS placed across transformer secondary windings to clamp common-mode and differential-mode transients simultaneously. Use Value: Fast <1 ns response and symmetrical 27 V VBR ensure minimal signal distortion while meeting GR-1089-CORE surge immunity requirements. |
Use Scenario: Protecting gate drivers and bootstrap circuits in BLDC motor inverters inside washing machines and HVAC systems from inductive kickback. IC Role / Device Role / Timing Role: TVS installed across half-bridge DC-link rails or gate-source paths to suppress voltage spikes during MOSFET commutation. Use Value: 37.5 V clamping voltage prevents gate oxide breakdown in 60 V-rated MOSFETs, extending system lifetime under frequent motor start-stop cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28CA | 28 V VBR min/max (26.6–29.4 V); same SMB package; 400 W PPPM rating. | Lower surge capacity limits use in high-energy environments like industrial motor controls or telecom central offices. | Select when lower clamping voltage tolerance and reduced surge margin are acceptable for cost-sensitive consumer designs. |
| P6SMB27CAHE3_B | AEC-Q101 qualified; identical electrical specs; same SMB package; HE3 suffix denotes automotive grade. | Required for automotive production where qualification to AEC-Q101 is mandatory (e.g., body electronics, infotainment power rails). | Choose for automotive OEM programs needing documented reliability and extended temperature validation - not a drop-in replacement due to qualification status. |
Compared with P6SMB27CA-E3/52, SMAJ28CA offers lower surge robustness but broader distributor availability, while P6SMB27CAHE3_B provides identical clamping performance with certified automotive qualification - enabling direct substitution only where AEC-Q101 compliance is contractually required.

FAQ
What is the standoff voltage (VWM) of the P6SMB27CA-E3/52?
The P6SMB27CA-E3/52 has a maximum reverse standoff voltage (VWM) of 23.1 V. This value represents the highest continuous DC or RMS voltage the device can block without entering avalanche conduction, providing a safety margin below its 25.7–28.4 V breakdown range. It is critical for selecting appropriate overvoltage protection in 24 V systems where normal operating voltage must remain well below clamping onset.
Is the P6SMB27CA-E3/52 unidirectional or bidirectional?
The P6SMB27CA-E3/52 is a bidirectional TVS diode, indicated by the "CA" suffix. It clamps transients equally in both polarities without polarity marking on the SMB (DO-214AA) package. This makes it ideal for protecting AC-coupled data lines, transformer-isolated interfaces, or floating power domains where voltage reversals occur - unlike unidirectional variants (e.g., P6SMB27A) that require correct cathode orientation.
What is the maximum clamping voltage (VC) of the P6SMB27CA-E3/52 at rated surge current?
The P6SMB27CA-E3/52 exhibits a maximum clamping voltage (VC) of 37.5 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 16.0 A. This parameter defines the upper voltage limit imposed on the protected circuit during worst-case surge events and directly informs the voltage rating selection of downstream components such as microcontrollers, transceivers, or MOSFETs.
Does the P6SMB27CA-E3/52 meet automotive qualification standards?
The P6SMB27CA-E3/52 is a commercial-grade RoHS-compliant part and is not AEC-Q101 qualified. For automotive applications requiring formal qualification, the functionally identical P6SMB27CAHE3_B variant is available - it shares the same electrical characteristics and SMB package but carries full AEC-Q101 certification for use in body electronics, infotainment, and ADAS subsystems.
What PCB layout guidance applies to the P6SMB27CA-E3/52 for optimal thermal performance?
To achieve rated 5.0 W power dissipation and maintain junction temperature within limits, the P6SMB27CA-E3/52 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Reducing pad area increases thermal resistance beyond the rated 100 °C/W, leading to premature thermal runaway during repetitive surges - especially critical in enclosed industrial enclosures or automotive under-hood environments.
