Product details
Overview
P6SMB10CAHE3_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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 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 P6SMB10CAHE3_A/I datasheet, P6SMB10CAHE3_A/I pinout, P6SMB10CAHE3_A/I application, or P6SMB10CAHE3_A/I equivalent, key selection criteria include bidirectional clamping performance, 10 V stand-off rating, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance of 100 °C/W junction-to-ambient.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<10 μA at VWM), while the low incremental surge resistance supports effective energy diversion during fast transients.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1, supporting lead-free reflow up to 260 °C peak. Its 100 °C/W thermal resistance requires careful PCB copper pad design (0.2" × 0.2") to sustain repetitive 600 W pulses at ≤0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 10.5 V min / 11.6 V max at 1 mA - Confirmed avalanche initiation range under standardized test conditions. |
| VC (Clamping) | 14.5 V at 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress. |
| PPPM | 600 W - Sustains single 10/1000 μs surges up to this power level; derates above 25 °C ambient per fig. 2. |
| RθJA | 100 °C/W - Requires minimum 0.2" × 0.2" copper pads per terminal to achieve specified thermal performance. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Package | SMB (DO-214AA) - Surface-mount outline with 2.2 mm height; compatible with automated placement and reflow soldering. |

|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor signal lines (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector or IC input pins to limit transient voltage before it reaches sensitive analog front-ends or transceivers. Use Value: Maintains signal integrity under ISO 7637-2 Pulse 1/2/5a stress while meeting AEC-Q101 reliability requirements for 15-year automotive service life. | Use Scenario: Safeguarding digital and analog I/O channels on programmable logic controller (PLC) modules exposed to relay coil flyback, motor drive noise, and field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage suppression element on 24 V DC inputs/outputs, positioned upstream of optocouplers or level-shifting buffers. Use Value: Limits clamped voltage to 14.5 V, ensuring downstream components remain within absolute maximum ratings during repeated 600 W transients. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Shielding secondary-side DC outputs of wall adapters and USB PD chargers against ESD and line-induced surges during plug/unplug events. IC Role / Device Role / Timing Role: Final-stage transient suppressor on regulated 5 V/9 V/12 V rails, placed after DC-DC converters and before USB connectors or device ports. Use Value: Provides sub-100 ns response time and <10 μA leakage at 10 V, minimizing standby power loss while meeting IEC 61000-4-2 Level 4 ESD immunity. | Use Scenario: Protecting Ethernet PHY, RS-485, or DSL line drivers/receivers from lightning-induced surges and induced transients on outdoor or long-haul cabling. IC Role / Device Role / Timing Role: First-line defense on differential pairs or single-ended lines, mounted at board edge with controlled impedance layout. Use Value: Symmetrical clamping ensures balanced protection of differential signals without skew or common-mode disruption during 10/1000 μs surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | 400 W PPPM rating; SMA package (smaller footprint, higher RθJA ≈ 140 °C/W); same VWM/VC specs. | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 without enhanced PCB cooling. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with actual layout. |
| 1.5KE10CA | Through-hole DO-201 package; 1500 W PPPM; higher VC (17.5 V); larger size and manual assembly required. | Better suited for high-energy primary-side protection but incompatible with SMT-only production. | Choose for legacy through-hole designs or where higher surge margin justifies larger footprint and assembly cost. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHE3_A/I delivers optimal balance of 600 W surge handling, SMB footprint compatibility, AEC-Q101 qualification, and 14.5 V clamping-making it preferred for modern SMT automotive and industrial control designs requiring validated reliability and process compatibility.

FAQ
What is the clamping voltage of P6SMB10CAHE3_A/I at its rated peak pulse current?
The P6SMB10CAHE3_A/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The low clamping ratio (VC/VWM = 1.45) reflects efficient energy absorption without excessive overvoltage stress on downstream components.
Is P6SMB10CAHE3_A/I suitable for automotive applications?
Yes, P6SMB10CAHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in Vishay's ordering information and mechanical data tables. It undergoes rigorous stress testing-including temperature cycling, humidity bias, and mechanical shock-to meet automotive reliability requirements. Its bidirectional operation, 150 °C junction rating, and MSL Level 1 reflow compatibility make it appropriate for engine control units, body electronics, and ADAS sensor interfaces.
What does the "CA" suffix mean in P6SMB10CAHE3_A/I?
The "CA" suffix in P6SMB10CAHE3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB10A), the CA version has no cathode band marking and functions identically for positive and negative voltage excursions. This enables simplified layout for AC-coupled or differential signal lines without polarity orientation concerns.
What is the thermal resistance of P6SMB10CAHE3_A/I, and how does it affect layout?
P6SMB10CAHE3_A/I 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 value assumes the recommended pad layout per Vishay's package drawing. To maintain safe junction temperatures during repetitive 600 W pulses, designers must allocate sufficient copper area and avoid thermal bottlenecks-such as narrow traces or insufficient internal ground planes-that would increase effective RθJA beyond the rated value.
How does P6SMB10CAHE3_A/I differ from the non-AEC-Q101 P6SMB10CA-E3 variant?
P6SMB10CAHE3_A/I differs from P6SMB10CA-E3 primarily in qualification and traceability: the HE3 suffix confirms AEC-Q101 compliance, extended temperature validation, and automotive-grade lot traceability, while the "_A/I" denotes 13" tape-and-reel packaging (3200 units). Electrically and physically, both share identical VWM (10 V), VC (14.5 V), PPPM (600 W), and SMB package dimensions-but only P6SMB10CAHE3_A/I is approved for automotive safety-critical subsystems per OEM requirements.
