Product details
Overview
P6SMB11CAHE3/52 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 with 10/1000 μs waveform, 11 V breakdown voltage (VBR min/max = 10.5–11.6 V), and 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current - deployed for ESD and surge protection on signal lines in automotive sensor interfaces.
For engineers reviewing the P6SMB11CAHE3/52 datasheet, P6SMB11CAHE3/52 pinout, P6SMB11CAHE3/52 application, or P6SMB11CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.43), 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It exhibits fast response time (<1 ns), low incremental surge resistance, and stable clamping performance across -65 °C to +150 °C junction temperature range.
Designed for repetitive surge events at 0.01 % duty cycle, it delivers 600 W peak pulse power under standardized 10/1000 μs waveform testing while maintaining ≤5.0 μA reverse leakage at 9.4 V stand-off voltage (VWM). Its glass-passivated junction ensures robust reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - precise breakdown threshold ensuring consistent clamping onset across production lots |
| VWM | 9.4 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 15.6 V at 38.5 A - clamping voltage limiting downstream IC stress during 600 W transients |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, enabling protection against IEC 61000-4-5 Level 4 surges |
| TJ max | +150 °C - extended junction temperature rating supporting under-hood automotive use |
| RθJA | 100 °C/W - thermal resistance defining derating curve above 25 °C ambient for sustained power dissipation |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetrical node in bidirectional operation | No polarity marking required - identical electrical behavior in both directions for transient suppression |
| Cathode | Current exit terminal in forward bias; symmetrical node in bidirectional operation | Unmarked terminals confirm bidirectional functionality - no cathode band present on P6SMB11CAHE3/52 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity concerns |
| 600 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) in properly designed PCB layouts |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio TVS devices |
| MSL Level 1 (260 °C peak) | Allows standard reflow soldering without moisture sensitivity handling or baking requirements |
Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
|
Use Scenario: Protecting LIN/CAN transceiver inputs and outputs from load dump and inductive switching transients in vehicle body control modules. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt surge energy before reaching transceiver IC. Use Value: Maintains signal integrity during 12 V system transients up to ±300 V by clamping within 15.6 V, preventing transceiver latch-up or damage. |
Use Scenario: Safeguarding RS-485 and CAN FD physical layer nodes in factory automation controllers exposed to motor drive noise. IC Role / Device Role / Timing Role: Differential line protector mounted across A/B bus lines to suppress common-mode surges induced by nearby VFDs. Use Value: Limits bus voltage excursions to ≤15.6 V during 600 W transients, preserving data integrity and avoiding receiver saturation. |
| Consumer Audio Input Stage Protection | Telecom DSL Line Interface Protection |
|
Use Scenario: Shielding analog audio input circuits in smart speakers from ESD events during user handling or cable insertion. IC Role / Device Role / Timing Role: Low-capacitance TVS placed between jack tip/ring and codec input pins to divert human-body-model (HBM) discharges. Use Value: Clamps 8 kV contact ESD pulses within nanoseconds while adding <1 pF parasitic capacitance - no audible distortion or bandwidth loss. |
Use Scenario: Front-end protection of ADSL/VDSL line drivers and receivers against lightning-induced surges on outdoor copper pairs. IC Role / Device Role / Timing Role: Primary surge limiter installed before hybrid transformer and line driver IC to absorb multi-kV transients. Use Value: Withstands repeated 10/1000 μs surges up to 600 W without degradation, extending modem field lifetime in lightning-prone regions. |
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-T | Same SMB package, 600 W rating, but VBR = 12.2–13.5 V and VC = 17.0 V - higher clamping voltage and looser tolerance | Less precise voltage coordination with 3.3 V or 5 V logic rails; requires margin adjustment in low-voltage interface designs | Select when tighter VBR tolerance (±5 % vs. ±10 %) and lower VC are critical for protecting modern low-voltage ICs |
| 1.5SMC11CA | Higher-power 1500 W variant in larger SMC (DO-214AB) package; same VBR/VC specs but 2.5× footprint area | Not suitable for space-constrained layouts; better for high-energy industrial surge zones where PCB real estate permits | Choose only when system-level surge tests exceed 600 W requirements - otherwise P6SMB11CAHE3/52 offers optimal density/performance balance |
Compared with SMBJ11CA-T and 1.5SMC11CA, P6SMB11CAHE3/52 provides the tightest VBR tolerance (±5 %), lowest clamping voltage (15.6 V), and smallest footprint among AEC-Q101-qualified 11 V bidirectional TVS diodes - making it preferred for automotive and compact industrial designs requiring precise voltage coordination.

FAQ
What does the "CA" suffix indicate in P6SMB11CAHE3/52?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB11CAHE3/52 provides symmetrical clamping in both polarities, unlike unidirectional variants (e.g., P6SMB11A). This eliminates polarity marking requirements and enables direct placement across AC-coupled or differential signal paths without orientation constraints.
Is P6SMB11CAHE3/52 suitable for automotive applications?
Yes, P6SMB11CAHE3/52 carries AEC-Q101 qualification (indicated by the "HE3" suffix), confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. It is specified for operation from -65 °C to +150 °C and used in automotive body control modules, sensor interfaces, and infotainment systems.
What is the maximum clamping voltage of P6SMB11CAHE3/52 and at what current is it measured?
The maximum clamping voltage of P6SMB11CAHE3/52 is 15.6 V, measured at the peak pulse current (IPPM) of 38.5 A under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the thermal resistance of P6SMB11CAHE3/52 affect its power handling?
P6SMB11CAHE3/52 has a typical RθJA of 100 °C/W, meaning junction temperature rises 100 °C per watt dissipated in still air. For reliable 600 W pulse operation, PCB layout must include minimum 5.0 mm × 5.0 mm copper pads per terminal to achieve effective heat spreading and avoid thermal runaway during repetitive surges.
What packaging format is used for P6SMB11CAHE3/52 and what does "/52" signify?
P6SMB11CAHE3/52 is supplied in 7-inch plastic tape-and-reel format with 750 units per reel. The "/52" suffix specifies this delivery mode - distinct from "/5B" (13-inch reel, 3200 units) - and ensures compatibility with standard SMT pick-and-place equipment calibrated for 8 mm carrier tape width.
