Product details
Overview
P6SMB11CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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 sensitive ICs, MOSFETs, and sensor signal lines against inductive switching transients and lightning surges in automotive, industrial, and telecom systems.
For engineers reviewing the P6SMB11CAHE3_B/H datasheet, P6SMB11CAHE3_B/H pinout, P6SMB11CAHE3_B/H application, or P6SMB11CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, RoHS compliance, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients on data and power lines.
The P6SMB11CAHE3_B/H is thermally rated for continuous operation up to +150 °C junction temperature and meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C). Its 9.40 V stand-off voltage ensures reliable blocking during normal operation while triggering conduction only above 10.5 V (min) breakdown threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (10/1000 μs waveform); sustains high-energy surges without failure in automotive load-dump or ESD events |
| Stand-off Voltage (VWM) | 9.40 V; blocks normal operating voltages up to this level while remaining non-conductive |
| Clamping Voltage (VC) | 15.6 V at 38.5 A IPPM; limits transient voltage seen by downstream circuitry to safe levels |
| Breakdown Voltage (VBR) | 10.5–11.6 V at 1 mA test current; defines precise conduction onset for bidirectional protection |
| Junction Temperature Range | −65 °C to +150 °C; supports under-hood automotive and industrial ambient environments |
| Thermal Resistance (RθJA) | 100 °C/W; requires minimum 5.0 mm × 5.0 mm copper pads per terminal for rated power dissipation |
| AEC-Q101 Qualified | Yes (HE3 suffix with _B revision); validated for automotive electronics per stress-test requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (bidirectional) | Conducts surge current in either direction; connects to protected line |
| Cathode | Transient current exit point (bidirectional) | Completes surge path to ground or return rail; symmetric with Anode |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse rating | Handles IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) with margin in compact SMB footprint |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules requiring long-term field stability |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, simplifying SMT manufacturing flow |
| Glass-passivated junction | Ensures stable leakage (<5 μA at VWM) and repeatable breakdown over 1000+ surge events |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between signal line and chassis ground to shunt transients before they reach the IC input stage. Use Value: Maintains 9.40 V stand-off while clamping to 15.6 V, preserving signal integrity and preventing latch-up in AEC-Q100-compliant microcontrollers. |
Use Scenario: Shielding 24 V DC digital input modules in programmable logic controllers from relay coil flyback and EFT bursts. IC Role / Device Role / Timing Role: Primary surge suppression element across input terminals, coordinated with series impedance for IEC 61000-4-4/5 compliance. Use Value: Delivers 600 W pulse handling in SMB package-reducing board space vs. larger DO-214AB alternatives while meeting industrial immunity standards. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Safeguarding Ethernet PHY interfaces and RS-485 transceivers against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: First-line transient suppressor on differential pair, operating symmetrically to preserve common-mode rejection. Use Value: Bidirectional 10.5–11.6 V breakdown ensures balanced clamping on both conductors, minimizing skew and maintaining signal timing margins. |
Use Scenario: Secondary-side overvoltage protection on 12 V output rails of wall-mounted AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Standoff-rated clamp that activates only during fault conditions (e.g., feedback loop failure), not during normal regulation. Use Value: 15.6 V clamping voltage provides >20% headroom above nominal 12 V output, preventing damage to downstream USB-PD or PMIC controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same SMB package, 600 W rating, but VWM = 9.4 V, VC = 17.0 V at 35.3 A; no AEC-Q101 qualification | Targeted at commercial/industrial use only; lacks automotive reliability validation and MSL Level 1 assurance | Select when AEC-Q101 is not required and higher clamping voltage is acceptable for system-level margin |
| 1.5SMC11CA | Higher-power 1500 W variant in larger SMC (DO-214AB) package; VWM = 9.4 V, VC = 18.2 V at 82.4 A | Used where surge energy exceeds 600 W limits, e.g., main power input stages; requires larger PCB area | Choose when system-level testing reveals insufficient margin with 600 W rating, accepting increased footprint and cost |
Compared with SMBJ11CA and 1.5SMC11CA, the P6SMB11CAHE3_B/H uniquely combines AEC-Q101 qualification, MSL Level 1, and 600 W capability in the smallest standardized SMB footprint-making it optimal for space-constrained automotive and industrial edge nodes where reliability and manufacturability are co-prioritized.

FAQ
What does the "CA" suffix indicate in P6SMB11CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB11CAHE3_B/H provides symmetrical transient voltage suppression in both polarities-ideal for protecting AC-coupled lines, differential buses like CAN or RS-485, and floating sensor interfaces without polarity constraints. This differs from unidirectional "A" variants that require correct anode/cathode orientation.
Is P6SMB11CAHE3_B/H suitable for automotive applications?
Yes, P6SMB11CAHE3_B/H is AEC-Q101 qualified (as indicated by the HE3 suffix and _B revision code), tested for temperature cycling, humidity bias, and mechanical shock per automotive reliability standards. It is explicitly intended for under-hood and cabin electronics including body control modules, ADAS sensors, and infotainment power supplies.
What is the maximum clamping voltage of P6SMB11CAHE3_B/H and at what current is it specified?
The maximum clamping voltage of P6SMB11CAHE3_B/H is 15.6 V, measured at a peak pulse current (IPPM) of 38.5 A using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is guaranteed across the full operating temperature range.
How does the SMB (DO-214AA) package of P6SMB11CAHE3_B/H compare to larger TVS packages like SMC?
The SMB (DO-214AA) package of P6SMB11CAHE3_B/H measures 3.94 mm × 2.20 mm × 1.75 mm-approximately 40% smaller than the SMC (DO-214AB) package-while delivering 600 W peak pulse power. This enables higher board density in space-limited designs, though thermal dissipation requires adherence to the specified 5.0 mm × 5.0 mm copper pad layout per terminal.
Does P6SMB11CAHE3_B/H require special handling or baking before reflow soldering?
No, P6SMB11CAHE3_B/H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be subjected to standard lead-free reflow profiles (peak ≤260 °C) without pre-baking. Its moisture-sensitive level classification eliminates process steps and reduces risk of popcorning during assembly.
