Overview
P6SMB200AHM3_A/H 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 industrial and automotive electronics against ESD and inductive switching transients.
For engineers reviewing the P6SMB200AHM3_A/H datasheet, P6SMB200AHM3_A/H pinout, P6SMB200AHM3_A/H application, or P6SMB200AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
The P6SMB200AHM3_A/H operates as a unidirectional avalanche diode with glass-passivated junction, delivering 600 W peak pulse power handling per 10/1000 µs waveform at 0.01 % duty cycle. Its cathode-band polarity marking enables unambiguous orientation during placement.
Designed for transient suppression in DC power lines and low-speed signal paths, it features low incremental surge resistance and fast response time (< 1 ns), with thermal derating defined up to 150 °C junction temperature and MSL Level 1 moisture sensitivity rating (peak reflow ≤ 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA test current - Confirmed avalanche initiation range; ensures predictable turn-on under overvoltage. |
| VC (Clamping Voltage) | 274 V at 2.2 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized transient waveform; validates robustness vs. IEC 61000-4-5. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on minimal 0.2" × 0.2" copper pads; guides PCB thermal layout requirements. |
| TJ max. | 150 °C - Maximum allowable junction temperature; sets upper limit for ambient + self-heating in sealed enclosures. |
| 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, halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (reverse-biased operation) | Connected to protected line; conducts during transient to shunt current to ground when voltage exceeds VBR. |
| Cathode | Current exit terminal (reverse-biased operation) | Connected to system ground or lower-potential rail; establishes polarity-sensitive clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against high-energy surges such as ISO 7637-2 Pulse 5a without derating in compact SMB footprint. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/52 | Same VWM/VBR/VC specs, but commercial-grade (not AEC-Q101 qualified); RθJA = 110 °C/W; MSL Level 1. | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC compliance is not required. | Select when cost sensitivity outweighs automotive reliability validation and thermal margin permits higher RθJA. |
| 1.5SMC200A | Same electrical ratings, but larger SMC (DO-214AB) package; higher IPPM (2.3 A); RθJA = 85 °C/W; no AEC-Q101 option. | Requires larger PCB area; better thermal performance but incompatible with dense SMB layouts. | Choose when board space allows and improved thermal dissipation justifies footprint increase and rework of land pattern. |

FAQ
What is the clamping voltage of P6SMB200AHM3_A/H at its rated peak pulse current?
The P6SMB200AHM3_A/H 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 Vishay's datasheet Figure 1 and Table on page 2, and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and supports design margining for downstream 300 V-rated components.
Is P6SMB200AHM3_A/H qualified for automotive applications?
Yes, P6SMB200AHM3_A/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in the Vishay P6SMB datasheet (Revision 09-Jan-2024, page 3, Note 1). It meets stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev G, making it suitable for under-hood and chassis-mounted automotive modules where reliability under thermal and mechanical stress is critical.
What does the "_A/H" suffix in P6SMB200AHM3_A/H indicate?
The "_A/H" suffix in P6SMB200AHM3_A/H denotes packaging configuration: "A" specifies the revision code (Revision A per Vishay's ordering table), and "H" indicates 7-inch plastic tape-and-reel delivery with 750 units per reel. This matches the preferred ordering format shown in the datasheet's Ordering Information table (page 3), confirming standard SMT-ready packaging for high-volume automated assembly.
How does the thermal resistance of P6SMB200AHM3_A/H affect PCB layout?
P6SMB200AHM3_A/H 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. To maintain TJ ≤ 150 °C under worst-case 5.0 W steady-state dissipation, PCB layout must provide ≥ 5.0 mm² copper area per pad and avoid thermal bottlenecks-such as narrow traces or internal layer isolation-that would elevate actual RθJA beyond the datasheet baseline.
Can P6SMB200AHM3_A/H be used in bidirectional configurations?
No, P6SMB200AHM3_A/H is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode-band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB200CA), which exhibit symmetrical clamping in both polarities. Using P6SMB200AHM3_A/H in bidirectional applications risks forward conduction and failure during negative transients; always verify polarity alignment in schematic and layout.
