Product details
Overview
P6SMB200CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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 provides robust overvoltage protection for signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom line cards.
For engineers reviewing the P6SMB200CAHE3_B/I datasheet, P6SMB200CAHE3_B/I pinout, P6SMB200CAHE3_B/I application, or P6SMB200CAHE3_B/I equivalent, key selection criteria include clamping voltage at rated surge current (274 V), AEC-Q101 qualification status, bidirectional polarity, thermal resistance (RθJA = 100 °C/W), and RoHS-compliant matte tin-plated terminals suitable for J-STD-002 soldering.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports consistent clamping performance under repetitive 10/1000 μs surges at 0.01% duty cycle.
The device is designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads per terminal and meets MSL level 1 per J-STD-020 with a maximum reflow peak temperature of 260 °C. Its junction temperature range spans −65 °C to +150 °C, supporting operation in under-hood automotive and high-ambient industrial environments.

|---|---|
Use Scenario: Protecting LIN/CAN transceiver supply pins and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between protected node and ground or rail. Use Value: Clamps transients to ≤274 V while maintaining <1.0 μA leakage at 200 V nominal rail, preserving sensor accuracy and MCU input thresholds. | Use Scenario: Shielding RJ45 magnetics and PHY ICs from ESD (IEC 61000-4-2) and surge (IEC 61000-4-5) on 10/100BASE-TX data lines. IC Role / Device Role / Timing Role: Low-capacitance TVS placed differential across pairs or common-mode to chassis ground. Use Value: Symmetrical clamping ensures equal protection for both polarities of fast-rising transients without polarity-dependent layout constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR/VC ratings, identical SMB package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC200CA | Higher package thermal resistance (RθJA ≈ 125 °C/W), larger SMC (DO-214AB) footprint | Requires PCB layout change; lower power density than SMB form factor | Choose only if existing design uses SMC footprint and higher surge margin is needed |
Compared with SMBJ200CA and 1.5SMC200CA, P6SMB200CAHE3_B/I uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and verified 600 W surge capability-making it optimal for space-constrained automotive and industrial designs requiring production-grade reliability.

FAQ
What is the clamping voltage of P6SMB200CAHE3_B/I at its rated peak pulse current?
The P6SMB200CAHE3_B/I has a maximum clamping voltage (VC) of 274 V at its rated peak pulse current (IPPM) of 2.2 A, measured under the standardized 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events. The clamping performance is validated across the full operating temperature range and is integral to its IEC 61000-4-5 compliance profile. P6SMB200CAHE3_B/I maintains this specification with no derating required up to +125 °C ambient.
Is P6SMB200CAHE3_B/I suitable for automotive applications?
Yes, P6SMB200CAHE3_B/I is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix in its ordering code and Vishay's official documentation. It undergoes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-meeting requirements for under-hood and cabin-mounted ECUs. P6SMB200CAHE3_B/I is explicitly recommended for automotive sensor protection, LIN/CAN bus interfaces, and body control module power rails.
What does the "CA" suffix indicate in P6SMB200CAHE3_B/I?
The "CA" suffix in P6SMB200CAHE3_B/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB200A), P6SMB200CAHE3_B/I has no polarity marking and functions identically regardless of voltage polarity applied across its terminals. This eliminates orientation concerns during automated placement and simplifies layout for differential or AC-coupled signal paths.
What is the thermal resistance of P6SMB200CAHE3_B/I, and how does it affect PCB layout?
P6SMB200CAHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet; reducing pad area increases thermal resistance and risks exceeding TJ max of +150 °C under sustained 5.0 W power dissipation. P6SMB200CAHE3_B/I must be placed with adequate copper pour and avoid thermal isolation to maintain reliability in high-ambient environments.
How does the "B/I" suffix in P6SMB200CAHE3_B/I impact packaging and logistics?
The "B/I" suffix in P6SMB200CAHE3_B/I specifies AEC-Q101 qualification ("B") and 13-inch diameter plastic tape-and-reel delivery mode ("I"), containing 3200 units per reel. This format supports high-volume SMT line feeding and aligns with industry-standard feeder compatibility. P6SMB200CAHE3_B/I reels are labeled with Vishay's traceable lot codes and comply with RoHS and halogen-free requirements per the HE3 base designation. No additional moisture sensitivity precautions are needed beyond standard MSL Level 1 handling.
