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 VWM (200 V), identical SMB package, but not AEC-Q101 qualified; lower production traceability for automotive use. | Limited to commercial/industrial designs where automotive qualification is not mandated. | Select when cost sensitivity outweighs automotive compliance requirements and full lifecycle support is not needed. |
| 1.5SMC200CA | Higher package thermal resistance (RθJA ≈ 125 °C/W vs. 100 °C/W); same VWM/VBR but larger SMC (DO-214AB) footprint. | Requires PCB layout change; suited for higher average power dissipation scenarios where SMB thermal limits are exceeded. | Choose only if sustained surge repetition rate exceeds P6SMB200CAHE3_B/H derating envelope and board space allows SMC placement. |
Compared with SMBJ200CA and 1.5SMC200CA, P6SMB200CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint, and 100 °C/W thermal resistance-making it the optimal choice for space-constrained automotive modules requiring validated reliability and seamless SMT integration.

FAQ
What does the "CA" suffix indicate in P6SMB200CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration: the device provides symmetrical transient voltage suppression for both positive and negative polarity surges without polarity marking. Unlike unidirectional variants (e.g., P6SMB200A), P6SMB200CAHE3_B/H has no cathode band and functions identically regardless of voltage polarity applied across its terminals-critical for differential signal lines like CAN or RS-485.
Is P6SMB200CAHE3_B/H suitable for automotive applications?
Yes, P6SMB200CAHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation revision 09-Jan-2024 (Document Number: 88370). It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and mechanical shock-making it appropriate for engine control units, body electronics, and ADAS modules where zero-defect reliability is mandatory.
What is the maximum clamping voltage of P6SMB200CAHE3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB200CAHE3_B/H is 274 V, measured at peak pulse current (IPPM) of 2.2 A with a 10/1000 μs waveform. This value represents the highest voltage imposed on protected circuitry during standardized surge events and is guaranteed across the full operating temperature range per Vishay's Electrical Characteristics table on page 2 of document 88370.
How does the SMB (DO-214AA) package of P6SMB200CAHE3_B/H compare to SMC (DO-214AB)?
The SMB package of P6SMB200CAHE3_B/H measures 4.57 mm × 3.94 mm × 2.20 mm, offering a 30 % smaller footprint than SMC (DO-214AB). While both share similar thermal performance under defined pad layouts, SMB enables denser PCB routing and is optimized for high-speed automated placement-whereas SMC variants like 1.5SMC200CA trade size for marginally higher thermal mass in less space-constrained designs.
What is the reverse leakage current specification for P6SMB200CAHE3_B/H at rated VWM?
P6SMB200CAHE3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 200 V and TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and prevents unnecessary power drain in battery-operated systems-verified per the Electrical Characteristics table on page 2 of Vishay document 88370.
