Product details
Overview
P6SMB200AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial systems against ESD and lightning-induced transients.
For engineers reviewing the P6SMB200AHE3/52 datasheet, P6SMB200AHE3/52 pinout, P6SMB200AHE3/52 application, or P6SMB200AHE3/52 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, 600 W peak pulse power handling under 10/1000 μs waveform, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and unidirectional polarity with cathode band marking.
Technical Context
The P6SMB200AHE3/52 employs a glass-passivated silicon junction optimized for fast transient response (<1 ps typical), low incremental surge resistance, and stable clamping behavior across temperature. Its unidirectional architecture provides forward conduction path only during reverse overvoltage events, enabling integration into DC-biased circuits without forward leakage concerns.
Designed for automated SMT placement on standard PCB pads (0.2" × 0.2"), it meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C) and supports repetitive surge duty cycles up to 0.01 %, with derating above TA = 25 °C per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 171 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR (Breakdown min) | 190 V - Minimum voltage at which device enters avalanche breakdown at 1 mA test current; defines turn-on threshold consistency. |
| VC (Clamping max) | 274 V - Maximum voltage seen by protected circuit during 2.2 A 10/1000 μs transient; determines safe margin above system rail. |
| PPPM | 600 W - Peak pulse power dissipation capability under standardized 10/1000 μs waveform; indicates robustness against lightning surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs PCB thermal design requirements. |
| TJ max | +150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in vehicle lighting modules against load dump transients up to 60 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC/DC converter input to clamp surges before they reach sensitive regulators. Use Value: Limits transient voltage to ≤274 V, preserving downstream 36 V-rated components while surviving 600 W peak energy per event. | Use Scenario: Safeguarding analog inputs of PLC analog I/O modules connected to 4–20 mA current loops exposed to field wiring ESD. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt fast-rising ESD strikes (IEC 61000-4-2 ±8 kV contact) away from op-amp front-end. Use Value: Sub-nanosecond response ensures clamping initiates before op-amp input stage damage occurs, with <1 μA leakage at 171 V ensuring signal integrity. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding Ethernet PHY power pins and bias rails in outdoor telecom base station line cards from induced lightning surges. IC Role / Device Role / Timing Role: Unidirectional TVS deployed on +3.3 V and +12 V bias supplies feeding PHY ICs and magnetics. Use Value: 274 V clamping voltage prevents latch-up in 3.3 V logic while 600 W rating handles multi-kA induced currents from nearby strikes. | Use Scenario: Suppressing commutation spikes generated by brushed DC motors in smart home appliances (e.g., vacuum cleaners, power tools). IC Role / Device Role / Timing Role: TVS placed across motor terminals to clamp inductive kickback exceeding 200 V during PWM switching. Use Value: 190–210 V VBR range aligns precisely with motor back-EMF peaks, ensuring reliable triggering without false trips during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/52 | Same VWM/VBR/VC specs but 400 W PPPM; SMA package (DO-214AC), RθJA = 110 °C/W | Limited to lower-energy transients; less suitable for automotive load dump where 600 W is required | Select when cost or board space is prioritized over peak surge margin and AEC-Q101 compliance is not mandatory. |
| 1.5SMC200AHE3_A/H | Same 600 W rating and AEC-Q101 qualification, but SMC (DO-214AB) package; larger footprint, RθJA = 75 °C/W | Better thermal performance but requires 30 % more PCB area; suited for high-temperature ambient designs | Choose when thermal management is critical and layout allows larger SMC footprint. |
Compared with SMAJ200A-E3/52, P6SMB200AHE3/52 delivers 50 % higher surge power headroom and automotive qualification; versus 1.5SMC200AHE3_A/H, it trades thermal efficiency for compact SMB size-ideal for space-constrained automotive ECUs where 100 °C/W RθJA is acceptable.

FAQ
What is the clamping voltage of P6SMB200AHE3/52 at its rated peak pulse current?
The P6SMB200AHE3/52 has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the highest voltage the protected circuit will experience during a full-rated transient event. The P6SMB200AHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is P6SMB200AHE3/52 suitable for automotive applications?
Yes, P6SMB200AHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it appropriate for under-hood and cabin automotive systems such as body control modules and ADAS power supplies. The P6SMB200AHE3/52 also meets MSL Level 1 for lead-free reflow compatibility.
What does the "HE3/52" suffix indicate in P6SMB200AHE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "/52" specifies packaging in 7-inch diameter plastic tape and reel with 750 units per reel. This ordering code aligns with Vishay's standard format for automotive-grade SMB devices and ensures traceability, controlled moisture sensitivity, and compatibility with high-speed pick-and-place equipment. The P6SMB200AHE3/52 is shipped in dry-packed reels meeting J-STD-033 requirements.
How does P6SMB200AHE3/52 differ from bidirectional variants like P6SMB200CAHE3/52?
P6SMB200AHE3/52 is unidirectional, featuring a cathode band and conducting only in reverse avalanche mode-ideal for DC-biased rails. In contrast, P6SMB200CAHE3/52 is bidirectional with symmetrical clamping in both polarities and no polarity marking, suited for AC lines or differential signal pairs. Their VWM ratings differ: P6SMB200AHE3/52 has 171 V, whereas the bidirectional version is rated at 171 V peak *per direction*, resulting in lower effective standoff for AC waveforms. The P6SMB200AHE3/52 cannot substitute for bidirectional use without circuit redesign.
What is the maximum operating temperature for P6SMB200AHE3/52?
The P6SMB200AHE3/52 has a maximum junction temperature (TJ) of +150 °C and an operating ambient temperature range of -65 °C to +150 °C. Its thermal resistance (RθJA) is 100 °C/W when mounted on 0.2" × 0.2" copper pads, meaning at 5.0 W steady-state power dissipation, junction temperature rises 500 °C above ambient-so practical continuous operation requires limiting DC power to <50 mW. The P6SMB200AHE3/52 is rated for transient-only duty, not sustained power dissipation.
