Product details
Overview
P6SMB27CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 27 V breakdown voltage (VBR = 25.7–28.4 V at IT = 1.0 mA), 23.1 V stand-off voltage (VWM), and 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM). It delivers 600 W peak pulse power (10/1000 µs waveform) and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB27CAHE3/5B datasheet, P6SMB27CAHE3/5B pinout, P6SMB27CAHE3/5B application, or P6SMB27CAHE3/5B equivalent, this device is selected for robust ESD and surge suppression on bidirectional signal lines, sensor interfaces, and power rails where low clamping voltage, fast response (<1 ns), and automotive-grade reliability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling transient suppression without polarity sensitivity-ideal for AC-coupled or differential signal paths. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable clamping performance under repetitive surges.
The device uses a planar silicon avalanche structure optimized for low incremental surge resistance and tight VBR tolerance (±5%), with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = +150 °C when mounted per recommended 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines precise avalanche initiation threshold for bidirectional clamping |
| VWM | 23.1 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA; sets safe operating margin below VBR |
| VC @ IPPM | 37.5 V at 16.0 A - clamped voltage during 600 W transient; determines protected circuit's maximum stress level |
| PPPM | 600 W (10/1000 µs) - peak surge energy handling capacity; validates compliance with IEC 61000-4-5 Level 4 |
| Leakage (ID) | <1.0 µA at VWM - negligible standby power loss and signal integrity impact on high-impedance nodes |
| TJ max. | +150 °C - enables use in under-hood automotive environments and industrial enclosures without derating |
| Package | SMB (DO-214AA) - standardized SMT footprint compatible with automated placement and reflow (MSL Level 1, 260 °C peak) |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated terminals, solderable per J-STD-002/JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | One terminal of symmetrical avalanche junction; conducts during negative transients relative to cathode reference |
| Cathode | Transient current entry (positive half-cycle) | Other terminal of symmetrical junction; conducts during positive transients-functionally identical to anode in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity testing up to Level 4 (4 kV line-to-line, 2 kV line-to-ground) |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, ADAS sensors, and infotainment power rails |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to downstream ICs-critical for 3.3 V/5 V logic and analog front-ends |
| MSL Level 1 moisture sensitivity | Enables standard reflow assembly without dry-pack or baking; reduces manufacturing overhead |
| Glass passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress |
Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., temperature, pressure) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC pin to shunt transients before they reach sensitive input stages. Use Value: Maintains signal integrity during 100 V/100 ms load dump events while adding <1 pF capacitance-no timing skew or data corruption. | Use Scenario: Safeguarding CAN FD physical layer (PHY) transceivers against ISO 11898-2 fast transient bursts and coupled noise in factory automation networks. IC Role / Device Role / Timing Role: Low-capacitance TVS placed across CAN_H/CAN_L differential pair to clamp common-mode surges without distorting bit timing. Use Value: Clamps to ≤37.5 V within <1 ns, preserving CAN bit timing margins and preventing bus lock-up during 4 kV EFT events. |

IC Role / Device Role / Timing Role: Standalone bidirectional suppressor co-located with port connector to absorb ±15 kV contact discharge per IEC 61000-4-2. Use Value: Sub-1 ns response and <1.0 µA leakage prevent false detection or power delivery negotiation failure during normal operation. | Use Scenario: Protecting ADSL/VDSL line drivers and receivers from lightning-induced surges on twisted-pair telecom lines. IC Role / Device Role / Timing Role: Primary surge limiter installed at line interface transformer secondary to limit voltage seen by PHY ICs. Use Value: Withstands 600 W pulses while limiting clamping voltage to 37.5 V-well below 50 V absolute maximum rating of most DSL transceivers. |
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 | Same SMB package, VBR = 29.1–32.1 V, VC = 45.4 V at 13.2 A, lower peak power (400 W) | Higher clamping voltage reduces margin for 3.3 V systems; suitable only where 45.4 V clamping is acceptable | Select SMAJ28CA only if cost sensitivity outweighs clamping performance and surge rating requirements |
| 1.5KE27CA | Through-hole DO-201 package, same VBR/VC, 1500 W rating but larger footprint and incompatible with SMT assembly | Requires PCB redesign and manual/through-hole assembly; not viable for high-density automotive modules | Choose 1.5KE27CA only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMAJ28CA and 1.5KE27CA, P6SMB27CAHE3/5B provides superior clamping (37.5 V vs. 45.4 V), full SMT compatibility, and AEC-Q101 qualification-making it the preferred choice for new automotive and industrial designs requiring compact, reliable, and production-ready surge protection.

FAQ
What is the breakdown voltage range of the P6SMB27CAHE3/5B?
The P6SMB27CAHE3/5B has a specified breakdown voltage (VBR) range of 25.7 V to 28.4 V at test current IT = 1.0 mA, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 24 V automotive systems where overvoltage margin must be precisely controlled.
Is the P6SMB27CAHE3/5B suitable for automotive applications?
Yes, the P6SMB27CAHE3/5B is AEC-Q101 qualified (indicated by the "HE3" suffix) and rated for operation from −65 °C to +150 °C junction temperature. Its construction-glass-passivated junction, MSL Level 1 reflow compatibility, and 100% lead-free matte tin plating-meets automotive manufacturing and reliability requirements, making it appropriate for engine control, body electronics, and ADAS sensor protection.
What does the "CA" suffix mean in P6SMB27CAHE3/5B?
The "CA" suffix in P6SMB27CAHE3/5B denotes a bidirectional configuration: the device functions identically in both polarities, with symmetrical breakdown and clamping characteristics. Unlike unidirectional variants (e.g., P6SMB27A), it requires no polarity orientation during placement and is used where AC signals, differential buses, or undefined voltage polarity demand dual-quadrant protection.
What is the maximum clamping voltage of the P6SMB27CAHE3/5B under surge conditions?
The P6SMB27CAHE3/5B clamps to a maximum of 37.5 V at its rated peak pulse current of 16.0 A (10/1000 µs waveform). This value-verified per JEDEC standards-is the upper bound of voltage imposed on protected circuitry during worst-case transients, directly determining whether downstream components (e.g., 3.3 V microcontrollers or CAN transceivers) remain within safe operating limits.
How does the P6SMB27CAHE3/5B differ from the unidirectional P6SMB27AHE3/5B?
The P6SMB27CAHE3/5B is bidirectional with symmetrical VBR, VC, and leakage in both directions and no polarity marking; the unidirectional P6SMB27AHE3/5B has a cathode band, conducts only in reverse bias, and exhibits forward voltage drop (~3.5 V at 50 A). Use P6SMB27CAHE3/5B for AC, differential, or polarity-agnostic protection; choose P6SMB27AHE3/5B only for DC rail protection with defined ground reference.
