Product details
Overview
P6SMB10CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 41.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB10CAHM3_B/I datasheet, P6SMB10CAHM3_B/I pinout, P6SMB10CAHM3_B/I application, or P6SMB10CAHM3_B/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<10 μA at VWM), while the low incremental surge resistance supports consistent clamping performance under repetitive 0.01% duty cycle pulses.
The device is thermally optimized for surface-mount use with RθJA = 100 °C/W and RθJL = 20 °C/W, and meets JESD201 Class 2 whisker resistance. Its 150 °C maximum junction temperature and halogen-free, RoHS-compliant HM3 construction align with automotive-grade reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown) | 10.5 V min / 11.6 V max at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on within spec. |
| VC (Clamping) | 14.5 V at IPPM = 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; limits stress on downstream ICs. |
| PPPM | 600 W - Sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure when mounted per recommended pad layout. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Standardized 2-pin SMT outline with 0.220" × 0.130" footprint; compatible with JEDEC-standard reflow profiles. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control modules, ADAS sensors, and body electronics. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Acts as cathode during positive transients and anode during negative transients; symmetrical conduction enables AC line protection. |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode in CA devices; no functional distinction-both terminals serve as interchangeable surge shunt nodes. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential pairs, AC signals, or ungrounded buses without polarity concerns. |
| 600 W peak pulse power | Withstands ISO 16750-2 and IEC 61000-4-5 surge events common in 12 V/24 V automotive systems. |
| AEC-Q101 qualified (HM3_B/I) | Validated for automotive production use including temperature cycling, humidity bias, and mechanical shock testing. |
| MSL Level 1 (260 °C peak) | Eliminates pre-bake requirement prior to reflow, reducing manufacturing complexity and cost. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and automotive material compliance standards (e.g., GMW3172). |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt transients before reaching PHY layer. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V sensor interface ICs during 12 V system-level surges up to 600 W. | Use Scenario: Safeguarding PLC digital input modules against field-wiring induced transients from solenoid switching or motor contactors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input lines, positioned upstream of optocoupler or Schmitt-trigger input stage. Use Value: Maintains signal integrity by limiting transient voltage to ≤14.5 V, ensuring reliable logic-level recognition under repeated 10/1000 μs surges. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHY magnetics and PoE controller inputs from lightning-induced surges on outdoor data links. IC Role / Device Role / Timing Role: Secondary protection device after gas discharge tube (GDT), providing fast-response clamping for residual energy. Use Value: Reduces clamping overshoot to 14.5 V, preventing damage to IEEE 802.3af/at compliant silicon while supporting >1 kV surge immunity. | Use Scenario: Input-stage transient suppression in USB-C PD adapters and wall-mounted AC/DC converters exposed to mains-borne noise. IC Role / Device Role / Timing Role: First-line defense on secondary-side 12 V/20 V rails, absorbing coupling from primary-side Y-capacitors or transformer leakage. Use Value: Limits voltage excursions to safe levels for synchronous rectifier MOSFETs and secondary-side controllers without derating design margins. |
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, SMA package (smaller thermal mass), higher RθJA (150 °C/W) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when space-constrained layouts prioritize footprint over automotive qualification and 600 W surge handling. |
| 1.5KE10CA | Through-hole DO-201 package, 1500 W PPPM, higher VC (17.5 V), slower response | Requires PCB through-holes; suited for board-level primary protection rather than IC-level clamping | Choose for legacy designs needing higher peak power but accepting larger size and manual assembly. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHM3_B/I delivers optimal balance of 600 W surge capability, AEC-Q101 compliance, and SMB footprint-making it the preferred choice for modern automotive and industrial SMT designs requiring validated reliability and precise clamping control.

FAQ
What does the "CA" suffix indicate in P6SMB10CAHM3_B/I?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB10CAHM3_B/I provides symmetrical clamping in both polarities-ideal for protecting AC-coupled signals, differential buses like CAN or RS-485, and ungrounded power rails without polarity constraints.
Is P6SMB10CAHM3_B/I suitable for automotive applications?
Yes, P6SMB10CAHM3_B/I is AEC-Q101 qualified (indicated by the HM3_B/I ordering code) and tested for temperature cycling, humidity bias, and mechanical shock-making it approved for use in engine control units, ADAS sensors, and body electronics where reliability under harsh conditions is mandatory.
What is the clamping voltage of P6SMB10CAHM3_B/I and why does it matter?
P6SMB10CAHM3_B/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current. This value defines the highest voltage imposed on protected circuitry during a transient event-ensuring downstream 3.3 V or 5 V ICs remain within absolute maximum ratings and avoid functional disruption or permanent damage.
How does the SMB (DO-214AA) package of P6SMB10CAHM3_B/I compare to SMA or SMC alternatives?
The SMB package of P6SMB10CAHM3_B/I offers higher power handling (600 W) than SMA (400 W) and smaller footprint than SMC (1500 W), with optimized thermal resistance (RθJL = 20 °C/W). It balances surge robustness, board space, and manufacturability-unlike SMA's lower power or SMC's larger land pattern and assembly constraints.
Does P6SMB10CAHM3_B/I require special PCB layout considerations?
Yes-P6SMB10CAHM3_B/I must 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. Smaller pads increase thermal impedance, reduce surge capability, and risk parametric shift or failure during repetitive transients.
