Product details
Overview
P6SMB200A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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). It delivers 600 W peak pulse power with a 10/1000 µs waveform and is designed for overvoltage protection of MOSFETs, ICs, and sensor signal lines in industrial and telecom systems.
For engineers reviewing the P6SMB200A-E3/52 datasheet, P6SMB200A-E3/52 pinout, P6SMB200A-E3/52 application, or P6SMB200A-E3/52 equivalent, this device serves as a RoHS-compliant, commercial-grade transient suppressor with verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for automated SMT assembly and high-reliability board-level ESD/surge protection.
Technical Context
The P6SMB200A-E3/52 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its 210 V minimum breakdown threshold (IT = 1 mA), with cathode polarity marked by a band. Its 274 V clamping voltage at 2.2 A ensures predictable voltage limiting during transients induced by inductive switching or lightning surges.
Thermally, it features a junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads and supports continuous power dissipation up to 5.0 W at 50 °C ambient. It is rated for operation from −65 °C to +150 °C and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below breakdown. |
| VBR (Breakdown Voltage) | 190–210 V at IT = 1 mA - Confirmed avalanche conduction onset; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy handling capability under standardized 10/1000 µs waveform at 0.01% duty cycle. |
| IPPM (Peak Pulse Current) | 2.2 A - Maximum non-repetitive surge current the device safely clamps without degradation. |
| RθJA | 100 °C/W - Thermal resistance defining junction temperature rise per watt on recommended PCB pad layout (0.2" × 0.2"). |
| Package | SMB (DO-214AA) - Low-profile SMT package with matte tin-plated leads, compatible with J-STD-002 soldering standards. |
Pinout & Package
SMB (DO-214AA) surface-mount package with cathode indicated by a molded band; terminals are matte tin-plated for compatibility with lead-free reflow processes. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to system ground or lower-potential node; defines polarity for unidirectional clamping. |
| Cathode | Avalanche conduction terminal | Marked with band; connected to line being protected; conducts reverse surge current to ground when VRM exceeded. |

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 ratings but in SMA (DO-214AC) package; 10% smaller footprint, higher RθJA (140 °C/W). | Limited to lower-power or space-constrained designs where thermal margin allows reduced pad area. | Select when board real estate is critical and peak surge duty is infrequent; verify thermal performance with actual layout. |
| 1.5SMC200A | Same electrical specs but in larger SMC (DO-214AB) package; lower RθJA (60 °C/W), higher IFSM (200 A). | Better suited for high-repetition surge environments or systems requiring higher forward surge immunity. | Choose for industrial power supplies or automotive ECUs needing enhanced thermal robustness and surge endurance beyond SMB limits. |
Compared with P6SMB200A-E3/52, SMAJ200A-E3/52 trades thermal performance for compactness, while 1.5SMC200A offers superior heat dissipation and surge current capacity at the cost of board area - making P6SMB200A-E3/52 the balanced choice for mainstream SMT designs requiring proven manufacturability and mid-tier surge handling.

FAQ
What is the clamping voltage of the P6SMB200A-E3/52 under a 10/1000 µs surge?
The P6SMB200A-E3/52 has a maximum clamping voltage (VC) of 274 V at a peak pulse current (IPPM) of 2.2 A with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The P6SMB200A-E3/52 maintains this clamping performance across its specified operating temperature range.
Is the P6SMB200A-E3/52 RoHS-compliant and halogen-free?
Yes, the P6SMB200A-E3/52 carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and exemption 7a. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P6SMB200A-M3/52) must be selected. Both variants meet JESD201 Class 2 whisker resistance and J-STD-002 solderability requirements.
What is the thermal resistance of the P6SMB200A-E3/52, and how does it affect layout?
The P6SMB200A-E3/52 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 the recommended pad layout from Vishay's datasheet 88370. Deviating from this layout increases junction temperature, potentially derating surge capability or accelerating parametric drift - so the P6SMB200A-E3/52 must be placed per the specified footprint for rated performance.
Does the P6SMB200A-E3/52 have AEC-Q101 qualification?
No, the P6SMB200A-E3/52 is a commercial-grade part. AEC-Q101 qualified versions exist in the P6SMB family but use different suffixes: "HE3" (e.g., P6SMB200AHE3_B/H) denotes RoHS-compliant AEC-Q101 qualification, while "HM3" adds halogen-free compliance. The P6SMB200A-E3/52 lacks automotive qualification and is intended for industrial, telecom, and consumer applications.
How does the P6SMB200A-E3/52 differ from bidirectional variants like P6SMB200CA?
The P6SMB200A-E3/52 is unidirectional, with polarity marked by a cathode band and intended for DC line protection where directionality is known. In contrast, P6SMB200CA is bidirectional, symmetrical in both directions, and used in AC-coupled or floating signal paths. Their VWM and VBR differ: P6SMB200A-E3/52 specifies 171 V VWM, while P6SMB200CA has 171 V VWM per polarity - meaning the P6SMB200A-E3/52 cannot substitute directly in AC applications without circuit redesign.
