Product details
Overview
P6SMB11CAHM3_B/I 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 standoff voltage. It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB11CAHM3_B/I datasheet, P6SMB11CAHM3_B/I pinout, P6SMB11CAHM3_B/I application, or P6SMB11CAHM3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable leakage performance (<5.0 μA at 9.40 V) and fast response time (<1.0 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
Designed for surface-mount use on 0.2" × 0.2" copper pads per terminal, it delivers 600 W peak pulse power under 10/1000 μs waveform with 0.01% duty cycle, and supports continuous power dissipation of 5.0 W at 50 °C ambient when mounted on infinite heatsink. Junction temperature range spans -65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy transients without failure during surge events |
| Standoff Voltage (VWM) | 9.40 V - maximum continuous reverse voltage before significant conduction begins |
| Clamping Voltage (VC at IPPM) | 15.6 V - limits downstream circuit voltage during 38.5 A transient, protecting 12 V systems |
| Breakdown Voltage (VBR min/max) | 10.5 V / 11.6 V - tight 10% tolerance ensures predictable turn-on across production lots |
| Leakage Current (ID at VWM) | <5.0 μA - negligible standby power loss and minimal signal distortion in high-impedance circuits |
| Operating Temperature Range | -65 °C to +150 °C - qualified for under-hood automotive and industrial environments |
| 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, halogen-free, RoHS-compliant, matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common node in bidirectional configuration | No polarity marking - symmetric terminals enable orientation-agnostic PCB layout |
| Cathode | Current exit point in forward bias; common node in bidirectional configuration | No polarity marking - identical to Anode electrically; device functions identically in either orientation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| AEC-Q101 qualification (HM3 suffix) | Validated reliability for automotive ECUs, ADAS sensors, and body control modules |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) on 2 Ω source impedance |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling |
Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
|
Use Scenario: Protecting CAN FD and LIN bus transceivers from load dump and ESD in engine control modules. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching PHY layer. Use Value: Clamps 15.6 V at 38.5 A while maintaining <5 μA leakage, ensuring signal integrity and preventing PHY latch-up during 12 V system operation. |
Use Scenario: Safeguarding PLC digital input channels exposed to 24 V DC field wiring with inductive kickback risk. IC Role / Device Role / Timing Role: Primary transient suppressor on each channel's input path, placed before optocoupler or Schmitt trigger input stage. Use Value: Limits voltage excursion to ≤15.6 V during 600 W surges, preserving input stage reliability without adding propagation delay or loading. |
| Telecom Line Card Surge Protection | Consumer USB Port ESD Shielding |
|
Use Scenario: Front-end protection for Ethernet PHYs and PoE injectors in enterprise switches subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level TVS deployed after gas discharge tube (GDT) to handle residual fast-rising transients. Use Value: Sub-1 ns response time and 15.6 V clamping ensure sensitive PHYs remain within absolute maximum ratings during combined GDT/TVS staged protection. |
Use Scenario: ESD protection for USB 2.0 data lines (D+/D-) in portable audio devices and smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed adjacent to USB connector to absorb ±8 kV contact discharge per IEC 61000-4-2. Use Value: 9.40 V standoff avoids false triggering during normal 3.3 V signaling, while 15.6 V clamping prevents damage to USB transceiver ESD structures. |
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 VWM (9.4 V), lower PPPM (400 W), SMA package (larger footprint, higher RθJA) | Limited to lower-energy transients; less suitable for automotive AEC-Q101-critical designs | Select when cost sensitivity outweighs AEC-Q101 requirement and surge energy stays below 400 W |
| 1.5SMC11CA | Same VWM and VC, higher PPPM (1500 W), SMC package (3.5 mm × 7.0 mm vs. SMB's 3.94 mm × 2.20 mm) | Requires larger PCB area; better for high-reliability industrial power supply inputs | Choose for higher surge margin where board space permits and thermal management allows larger case |

FAQ
What does the "CA" suffix indicate in P6SMB11CAHM3_B/I?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB11CAHM3_B/I provides symmetrical clamping in both polarities-ideal for protecting AC-coupled signals, differential buses like CAN or RS-485, and floating power domains without polarity constraints during layout or assembly.
Is P6SMB11CAHM3_B/I suitable for automotive applications?
Yes, P6SMB11CAHM3_B/I is AEC-Q101 qualified (indicated by the HM3 suffix), tested for high-temperature operating life, temperature cycling, and ESD robustness-making it appropriate for under-hood and cabin electronics including ADAS sensors, body control modules, and infotainment interfaces.
What is the maximum clamping voltage of P6SMB11CAHM3_B/I and at what current is it specified?
The maximum clamping voltage of P6SMB11CAHM3_B/I is 15.6 V, measured at 38.5 A peak pulse current using the standardized 10/1000 μs waveform-ensuring downstream 12 V logic and analog components remain within safe operating limits during surge events.
How does the SMB (DO-214AA) package of P6SMB11CAHM3_B/I compare to SMA or SMC alternatives?
The SMB package of P6SMB11CAHM3_B/I measures 3.94 mm × 2.20 mm, offering 30% smaller footprint than SMA and ~50% smaller than SMC-enabling dense routing in space-limited applications while maintaining 600 W surge capability and MSL Level 1 reflow compatibility not always achieved in smaller packages.
Does P6SMB11CAHM3_B/I require special PCB layout considerations?
Yes-P6SMB11CAHM3_B/I should be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power; inadequate copper area reduces thermal dissipation and degrades clamping performance during repetitive surges.
