Product details
Overview
P6SMB200CAHM3_A/H 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 600 W peak pulse power (10/1000 μs). It clamps transients to ≤274 V at 2.2 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive use.
For engineers reviewing the P6SMB200CAHM3_A/H datasheet, P6SMB200CAHM3_A/H pinout, P6SMB200CAHM3_A/H application, or P6SMB200CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, 200 V working voltage, 274 V max clamping voltage at IPPM, AEC-Q101 qualification, and SMB package compatibility with automated SMT assembly.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical bidirectional conduction-no polarity marking required. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, and its low incremental surge resistance enables effective energy diversion during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a).
Designed for mounting on 0.2" × 0.2" copper pads per terminal, it achieves thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation up to 150 °C junction temperature. The 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM/VBR/VC ratings but lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 | Select when board space is constrained and surge energy is ≤400 W |
| SMCJ200CA | Same VWM/VBR/VC, higher PPPM (1500 W), larger SMC package (DO-214AB), higher thermal mass | Overqualified for 600 W needs; requires larger PCB area and different reflow profile | Select when future-proofing for higher surge classes or extended thermal cycling life is required |
Compared with SMAJ200CA and SMCJ200CA, the P6SMB200CAHM3_A/H delivers optimal balance of 600 W surge capability, AEC-Q101 qualification, SMB footprint, and automotive-grade material compliance-making it the preferred choice for cost-sensitive, space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What does the "CA" suffix indicate in P6SMB200CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration: the P6SMB200CAHM3_A/H conducts symmetrically in both directions, making it suitable for AC-coupled or polarity-agnostic protection applications. Unlike unidirectional variants (e.g., P6SMB200A), it has no cathode marking and clamps equally on positive and negative transients.
Is P6SMB200CAHM3_A/H qualified for automotive use?
Yes-the "HM3" suffix confirms that P6SMB200CAHM3_A/H is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has undergone stress testing including high-temperature operating life (HTOL), temperature cycling (TCT), and unbiased highly accelerated stress testing (uHAST) per AEC-Q101 Rev G.
What is the maximum clamping voltage of P6SMB200CAHM3_A/H at rated surge current?
The P6SMB200CAHM3_A/H clamps to a maximum of 274 V at its rated peak pulse current (IPPM) of 2.2 A under the standard 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet (Document Number: 88370, Rev 09-Jan-2024) and verified across production lots.
How does the SMB package of P6SMB200CAHM3_A/H compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB200CAHM3_A/H offers a 4.57 mm × 3.94 mm footprint-larger than SMA (DO-214AC) but smaller than SMC (DO-214AB). It provides better thermal dissipation than SMA (RθJA = 100 °C/W vs. ~130 °C/W) while retaining compatibility with high-speed SMT placement and standard reflow profiles.
Can P6SMB200CAHM3_A/H be used in place of unidirectional TVS diodes?
No-P6SMB200CAHM3_A/H is strictly bidirectional and lacks polarity marking. Substituting it for a unidirectional part (e.g., P6SMB200AHM3_A/H) in DC-biased circuits may cause unintended conduction or failure to clamp correctly. Always verify circuit topology and bias conditions before replacement.
