Product details
Overview
P6SMB27CA-E3/5B 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 and power lines. It features a 23.1 V stand-off 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 a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB27CA-E3/5B datasheet, P6SMB27CA-E3/5B pinout, P6SMB27CA-E3/5B application, or P6SMB27CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA suffix configuration, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports rapid energy dissipation during transient events.
The device delivers consistent clamping performance across -65 °C to +150 °C operating range and maintains thermal stability with RθJA = 100 °C/W and RθJL = 20 °C/W. It meets JESD201 Class 2 whisker resistance and is qualified per AEC-Q101 when ordered with HE3/HM3 suffixes - though P6SMB27CA-E3/5B itself is commercial-grade RoHS-compliant.
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 mA - Confirmed breakdown range ensuring reliable turn-on during overvoltage events |
| VC (Clamping) | 37.5 V at 16.0 A - Peak voltage seen by protected circuit during 10/1000 μs transient; limits stress on downstream components |
| PPPM | 600 W - Peak pulse power handling capacity under standardized 10/1000 μs waveform; validates robustness against common ESD/lightning surges |
| IPPM | 16.0 A - Corresponding peak pulse current at VC; determines minimum trace width and layout clearance requirements |
| TJ max | +150 °C - Maximum junction temperature enabling operation in high-ambient environments like engine control units or power supplies |

Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Acts as cathode in one polarity; forms symmetrical clamping path with cathode terminal |
| Cathode | Transient current exit (bidirectional) | Acts as anode in opposite polarity; completes low-impedance surge shunt path to ground or rail |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded power rails without polarity constraints |
| 600 W peak pulse power | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line) when properly mounted on 5.0 mm × 5.0 mm copper pads |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing with sensors or communication ports |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking; simplifies manufacturing logistics for high-volume SMT lines |
| Glass passivated junction | Ensures long-term parameter stability and low leakage (<1 μA) across temperature and humidity stress conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28CA | Same SMB package, 28 V VBR, 41.5 V VC at 14.5 A, 400 W PPPM | Lower peak power rating reduces margin for high-energy surges; suitable only where IEC 61000-4-5 Level 3 is sufficient | Select SMAJ28CA only if system-level surge testing confirms 400 W is adequate and cost is prioritized over headroom |
| SMCJ28CA | Same VBR/VC specs but in larger SMC (DO-214AB) package; 1500 W PPPM, higher IPPM (43.3 A) | Requires larger PCB area and different pad layout; better suited for primary-side AC/DC input protection | Choose SMCJ28CA when protecting higher-power stages or when board space allows larger footprint for enhanced reliability |
Compared with SMAJ28CA, P6SMB27CA-E3/5B offers 50% higher peak pulse power (600 W vs. 400 W) for stronger surge immunity, while SMCJ28CA trades compactness for triple the power handling - making P6SMB27CA-E3/5B optimal for space-constrained secondary-side protection where 600 W is the design target.

FAQ
What is the clamping voltage of P6SMB27CA-E3/5B at its rated peak pulse current?
The P6SMB27CA-E3/5B has a maximum clamping voltage (VC) of 37.5 V at 16.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per the Vishay datasheet. The clamping voltage defines the upper voltage limit imposed on protected circuits during transient events, making it critical for ensuring downstream ICs remain within absolute maximum ratings. P6SMB27CA-E3/5B achieves this with a clamping ratio of approximately 1.33 relative to its nominal breakdown voltage.
Is P6SMB27CA-E3/5B suitable for automotive applications?
P6SMB27CA-E3/5B is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same die and electrical characteristics as AEC-Q101-qualified variants (e.g., P6SMB27CAHE3_B), the -E3/5B suffix indicates it is not formally AEC-Q101 certified. For non-safety-critical automotive subsystems - such as infotainment or body electronics - P6SMB27CA-E3/5B may be used with customer validation. However, for powertrain or ADAS applications requiring qualification, the HE3 or HM3 suffix versions must be selected. P6SMB27CA-E3/5B remains fully compatible in footprint and electrical behavior with those qualified parts.
What does the "CA" suffix mean in P6SMB27CA-E3/5B?
The "CA" suffix in P6SMB27CA-E3/5B denotes a bidirectional configuration - meaning the device functions identically in both forward and reverse bias directions, with symmetrical breakdown and clamping characteristics. Unlike unidirectional "A"-suffix parts that require correct polarity orientation, the CA version eliminates installation errors in AC-coupled or differential signal paths. This makes P6SMB27CA-E3/5B ideal for protecting RS-485, CAN, LIN, or audio lines where voltage polarity reverses during normal operation. The absence of a cathode band marking further confirms its bidirectional nature.
How is thermal performance characterized for P6SMB27CA-E3/5B?
P6SMB27CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured under standard JEDEC test conditions (25 °C ambient, 0.2" × 0.2" copper pads). These values define how effectively heat generated during surge events dissipates into the PCB and surrounding environment. At its 5.0 W steady-state power dissipation limit, the junction temperature rise above ambient is ~500 °C under worst-case RθJA - underscoring that P6SMB27CA-E3/5B is intended for transient, not continuous, power dissipation. Its 150 °C maximum junction temperature rating ensures safe operation even in high-ambient environments when used per spec.
What packaging format does P6SMB27CA-E3/5B ship in?
P6SMB27CA-E3/5B ships in 13-inch diameter plastic tape and reel packaging, with a base quantity of 3200 pieces per reel (ordering code suffix "/5B"). The tape conforms to EIA-481 standards and is compatible with high-speed pick-and-place equipment. Each device is oriented consistently in the carrier pockets, supporting automated assembly without manual orientation checks. The "E3" prefix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability requirements. This packaging format enables efficient SMT line integration and inventory management for medium-to-high volume production runs using P6SMB27CA-E3/5B.
