Product details
Overview
P6SMB200CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), designed to protect sensitive ICs and MOSFETs against inductive switching transients and ESD in industrial power supplies and automotive sensor interfaces.
For engineers reviewing the P6SMB200CAHE3/5B datasheet, P6SMB200CAHE3/5B pinout, P6SMB200CAHE3/5B application, or P6SMB200CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 600 W peak pulse power rating with 10/1000 μs waveform, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional structure. It features glass-passivated junctions for stable leakage performance and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
Clamping response is optimized for fast transient suppression (<1 ns typical), with incremental surge resistance minimized to sustain high IPPM under repetitive 0.01% duty cycle conditions. Its thermal design supports operation up to +150 °C junction temperature while dissipating 5.0 W continuously on infinite heatsink at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche conduction at 1 mA test current; ensures reliable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 274 V max at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity with standard 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature rating; supports deployment in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetric with cathode in bidirectional operation | No polarity marking required; terminals are interchangeable for AC transient suppression. |
| Cathode | Current exit terminal in forward bias; symmetric with anode in bidirectional operation | Identical electrical behavior to anode; enables clamping in both voltage polarities without external circuit modification. |
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 power (10/1000 μs) | Supports robust immunity to lightning-induced surges and inductive kickback in motor drives and power converters. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including engine control modules and ADAS sensor interfaces. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and compatibility with standard lead-free reflow profiles up to 260 °C peak. |
| Glass passivated junction | Ensures stable VBR and low ID over temperature and lifetime, critical for long-term field reliability. |
Applications
| Automotive Sensor Protection | Industrial Power Supply Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same SMB package, 200 V VWM, but rated for 600 W with 10/1000 μs waveform; no AEC-Q101 qualification; higher ID (5 μA vs. 1 μA) | Targeted at commercial/industrial use only; not validated for automotive temperature cycling or humidity testing | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive reliability validation |
| 1.5SMC200CA | Higher-power 1500 W variant in larger SMC (DO-214AB) package; same VWM/VBR/VC ratings; 200 °C TJ max | Used where higher surge repetition rate or longer pulse duration (e.g., 8/20 μs) demands greater energy absorption | Choose when system-level surge testing exceeds 600 W single-pulse requirement or PCB layout allows larger footprint |
Compared with SMBJ200CA and 1.5SMC200CA, P6SMB200CAHE3/5B uniquely combines AEC-Q101 qualification, ultra-low 1 μA leakage at VWM, and SMB footprint-making it optimal for space-constrained automotive and industrial designs requiring certified reliability without sacrificing clamping precision.

FAQ
What is the clamping voltage of P6SMB200CAHE3/5B at its rated peak pulse current?
The P6SMB200CAHE3/5B has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 2.2 A with a 10/1000 μs waveform. This value is measured under standardized test conditions defined in the Vishay datasheet and represents the upper voltage limit imposed on protected circuitry during a worst-case transient event. The clamping performance is consistent across both polarities due to the device's bidirectional architecture.
Is P6SMB200CAHE3/5B qualified for automotive applications?
Yes, P6SMB200CAHE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This certification confirms that the device has passed rigorous stress tests-including temperature cycling, high-temperature reverse bias, and ESD-required for automotive electronic modules. It is approved for use in engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh environmental conditions is mandatory.
What does the "CA" suffix mean in P6SMB200CAHE3/5B?
The "CA" suffix in P6SMB200CAHE3/5B denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both positive and negative voltage directions. Unlike unidirectional variants (e.g., P6SMB200A), this version has no cathode marking and functions identically regardless of voltage polarity-ideal for protecting AC-coupled lines, differential buses, or floating grounds without requiring orientation-aware placement.
What is the thermal resistance from junction to lead (RθJL) for P6SMB200CAHE3/5B?
The P6SMB200CAHE3/5B has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, as specified in the Vishay datasheet. This parameter reflects how effectively heat generated during surge events transfers from the silicon die to the PCB copper pads via the leads. Combined with its SMB package's low RθJA (100 °C/W), this enables reliable operation at +150 °C junction temperature even under repeated 600 W pulses with proper pad layout.
How does the "5B" in P6SMB200CAHE3/5B affect packaging and ordering?
"5B" in P6SMB200CAHE3/5B specifies the tape-and-reel delivery format: 13-inch diameter reel containing 3200 units. This contrasts with "52", which denotes a 7-inch reel holding 750 units. The "5B" option supports high-volume SMT production lines requiring fewer reel changes and optimized feeder setup, while maintaining identical electrical, thermal, and reliability characteristics as other variants in the P6SMB200CAHE3 family.
