Product details
Overview
P6SMB27CAHE3_A/I 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 27 V standoff voltage (VWM), 37.5 V maximum clamping voltage at 16.0 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB27CAHE3_A/I datasheet, P6SMB27CAHE3_A/I pinout, P6SMB27CAHE3_A/I application, or P6SMB27CAHE3_A/I equivalent, key selection criteria include bidirectional clamping behavior, 27 V working voltage, 37.5 V clamping performance under 16 A surge, SMB (DO-214AA) package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 23.1 V), while the low incremental surge resistance enables effective transient energy diversion without excessive voltage overshoot.
The device is rated for 150 °C maximum junction temperature and exhibits a ±0.096 %/°C temperature coefficient of breakdown voltage. It meets J-STD-020 MSL Level 1 moisture sensitivity and supports reflow soldering up to 260 °C peak, making it suitable for high-volume automated assembly in harsh-environment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 23.1 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for protected circuitry. |
| VBR (Breakdown Voltage) | 25.7–28.4 V at 1.0 mA - Voltage at which device transitions into avalanche conduction; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 37.5 V at 16.0 A IPPM - Maximum voltage seen by downstream circuit during 10/1000 μs surge; critical for IC-level protection margin. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy handling capacity per single 10/1000 μs event; enables robust ESD and load-switching surge suppression. |
| ID (Reverse Leakage) | <1.0 μA at 23.1 V - Minimal standby current draw; preserves signal integrity and battery life in always-on systems. |
| TJ max. | 150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial ambient environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow processes. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically regardless of orientation in circuit.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals serve as interchangeable surge current entry/exit points; no directional installation required for bidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity concerns. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-line) when properly laid out with recommended 5.0 mm × 5.0 mm copper pads. |
| Low clamping ratio (VC/VWM ≈ 1.62) | Minimizes overvoltage stress on protected ICs-critical for 3.3 V and 5 V logic rails where headroom is constrained. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profile usage without baking, reducing manufacturing complexity and cost. |

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 VWM, 45.4 V VC at 13.2 A, same SMB package but lower PPPM (400 W). | Limited to lower-energy transients; insufficient for IEC 61000-4-5 Level 4 compliance without derating. | Select when cost sensitivity outweighs peak surge requirement and layout space permits parallel devices. |
| SMCJ28CA | 28 V VWM, 45.4 V VC at 26.4 A, higher PPPM (1500 W), larger SMC (DO-214AB) package. | Requires PCB area increase (~2.5× footprint); suited for high-reliability industrial power inputs. | Choose when system-level surge test requirements exceed 600 W and board space allows larger package. |
Compared with SMAJ28CA and SMCJ28CA, P6SMB27CAHE3_A/I delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and compact SMB footprint-making it the preferred choice for space-constrained automotive and industrial signal-line protection where 27 V nominal rail alignment and production scalability matter.

FAQ
What does the "CA" suffix indicate in P6SMB27CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB27CAHE3_A/I provides symmetrical clamping in both polarities-ideal for protecting AC-coupled or differential signal paths like CAN bus or RS-485 without polarity constraints. This differs from unidirectional variants (e.g., P6SMB27A) that require correct cathode orientation.
Is P6SMB27CAHE3_A/I suitable for automotive applications?
Yes, P6SMB27CAHE3_A/I is AEC-Q101 qualified (indicated by the "HE3" suffix), making it suitable for automotive use cases including engine control, body electronics, and ADAS sensor interfaces. Its 150 °C junction rating, MSL Level 1 compliance, and validated surge performance meet stringent automotive reliability requirements.
What is the clamping voltage of P6SMB27CAHE3_A/I under surge conditions?
P6SMB27CAHE3_A/I has a maximum clamping voltage (VC) of 37.5 V at 16.0 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value represents the highest voltage imposed on protected circuitry during a defined transient event and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of P6SMB27CAHE3_A/I compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB27CAHE3_A/I measures 4.06 mm × 5.59 mm-smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). It offers a 600 W PPPM rating in a footprint optimized for high-density layouts, whereas SMA typically supports ≤400 W and SMC supports ≥1500 W. Thermal resistance (RθJA = 100 °C/W) reflects its moderate power dissipation capability.
Can P6SMB27CAHE3_A/I be used in place of a unidirectional TVS like P6SMB27A?
No-P6SMB27CAHE3_A/I is bidirectional and lacks polarity marking, while P6SMB27A is unidirectional with a cathode band. Substituting them requires circuit review: P6SMB27CAHE3_A/I may be used on AC or floating nodes, but cannot replace P6SMB27A on DC-biased lines where forward conduction must be blocked. Always verify schematic polarity and clamping symmetry requirements before substitution.
