Product details
Overview
P6SMB11CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 9.40 V stand-off voltage. It protects signal lines and power rails in automotive-grade sensor interfaces and industrial control I/O against ESD and inductive switching transients.
For engineers reviewing the P6SMB11CAHE3_A/H datasheet, P6SMB11CAHE3_A/H pinout, P6SMB11CAHE3_A/H application, or P6SMB11CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pads.
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 constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<5.0 μA at 9.40 V) across temperature.
The device delivers 600 W transient suppression under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and maintains clamping performance up to 150 °C junction temperature. Its SMB package supports JEDEC-compliant reflow profiles including peak soldering at 260 °C (MSL Level 1).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy transients without failure in automotive and industrial surge environments |
| Stand-off Voltage (VWM) | 9.40 V - defines maximum continuous reverse operating voltage before significant leakage begins |
| Clamping Voltage (VC) | 15.6 V at 38.5 A - limits downstream circuit voltage during surge, protecting 12 V rail ICs and MOSFETs |
| Breakdown Voltage (VBR) | 10.5–11.6 V at 1.0 mA - ensures reliable triggering within specified tolerance band |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in under-hood automotive and wide-temperature industrial settings |
| Thermal Resistance (RθJA) | 100 °C/W - determines required copper pad area (0.2" × 0.2") for safe power dissipation |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated terminals, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1, 260 °C peak reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking - symmetrical conduction enables use on AC or differential lines without orientation check |
| Cathode | Current exit point in forward bias; common terminal in bidirectional configuration | Identical electrical role to Anode - bidirectional operation means both terminals behave identically under reverse surge |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of balanced lines (e.g., RS-485, CAN FD) without external polarity management |
| 600 W peak pulse rating | Meets ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surge immunity requirements |
| AEC-Q101 qualification | Validated for automotive powertrain, body electronics, and ADAS sensor modules requiring long-term reliability |
| Glass passivated junction | Reduces parameter drift over time and improves stability under repeated surge stress vs. epoxy-passivated alternatives |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes protected circuit overvoltage margin, allowing tighter design margins for 12 V systems |
Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus and analog sensor outputs (e.g., temperature, pressure) in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry to shunt transients before reaching MCU ADC or LIN transceiver. Use Value: Maintains signal integrity below 15.6 V during 38.5 A surges, preventing latch-up or damage to 12 V tolerant interface ICs. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers subjected to relay coil flyback and field wiring ESD. IC Role / Device Role / Timing Role: Primary front-end surge suppressor on dry-contact inputs, mounted adjacent to terminal block. Use Value: Limits transient voltage to ≤15.6 V within nanoseconds, ensuring input Schmitt triggers remain within safe operating range. |
| Telecom Line Card Protection | Consumer Appliance Motor Control |
Use Scenario: Shielding Ethernet PHY magnetics and PoE detection circuitry from lightning-induced surges on outdoor-facing ports. IC Role / Device Role / Timing Role: Secondary-level protector after gas discharge tube (GDT), handling residual energy in differential mode. Use Value: Symmetrical clamping ensures equal suppression on both line pairs, preserving common-mode rejection in 10/100BASE-TX. |
Use Scenario: Guarding microcontroller GPIOs driving small brushed DC motors in smart home appliances (e.g., washing machine door lock actuator). IC Role / Device Role / Timing Role: Localized TVS at motor driver output to absorb inductive kickback during PWM commutation. Use Value: Fast response (<1 ns) and low clamping voltage prevent MCU reset or GPIO latch-up during 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 |
|---|---|---|---|
| SMAJ11CA | Same 11 V VWM and bidirectional function, but lower 400 W PPPM rating and SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; requires larger copper area for thermal management | Choose when cost sensitivity outweighs automotive qualification and 600 W headroom |
| 1.5KE11CA | Higher 1.5 kW PPPM rating but axial DO-201 package; not SMT-compatible and lacks AEC-Q101 qualification | Requires through-hole assembly and manual rework; unsuitable for automated high-volume production | Use only in legacy designs or prototyping where board space and assembly method permit axial components |
Compared with SMAJ11CA and 1.5KE11CA, P6SMB11CAHE3_A/H uniquely combines AEC-Q101 qualification, 600 W SMT-rated surge capacity, and SMB footprint-making it the preferred choice for new automotive and industrial designs requiring production scalability and long-term compliance assurance.

FAQ
What does the "CA" suffix indicate in P6SMB11CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB11CAHE3_A/H provides symmetrical clamping in both polarities-ideal for protecting AC-coupled signals, differential buses like RS-485, or ungrounded sensor outputs where polarity cannot be guaranteed. This differs from unidirectional "A" variants that require correct cathode orientation.
Is P6SMB11CAHE3_A/H qualified for automotive applications?
Yes, P6SMB11CAHE3_A/H is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). It has passed stress tests including high-temperature operating life, temperature cycling, and ESD, making it suitable for engine bay, chassis, and ADAS sensor modules.
What is the maximum clamping voltage of P6SMB11CAHE3_A/H and under what test condition?
The maximum clamping voltage of P6SMB11CAHE3_A/H is 15.6 V, measured at 38.5 A peak pulse current using the standardized 10/1000 μs double-exponential waveform. This value ensures downstream 12 V logic and analog circuits remain within safe operating limits during surge events.
How does the SMB (DO-214AA) package of P6SMB11CAHE3_A/H compare thermally to SMA or SMC packages?
P6SMB11CAHE3_A/H in SMB package has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads-lower than SMA (140 °C/W) but higher than SMC (60 °C/W). This makes SMB a balanced choice for moderate-power surge suppression with standard SMT process compatibility.
Can P6SMB11CAHE3_A/H replace P6SMB11A in an existing design?
No-P6SMB11CAHE3_A/H is bidirectional while P6SMB11A is unidirectional. Substituting them requires verifying circuit polarity, grounding scheme, and transient directionality. Unidirectional parts rely on correct cathode orientation; using a bidirectional part may alter clamping behavior in DC-biased paths and should be validated per application.
