Product details
Overview
P6SMB200A-E3/5B 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). It delivers 600 W peak pulse power with 10/1000 μs waveform and is designed for overvoltage protection of power rails and signal lines in industrial power supplies and automotive ECUs.
For engineers reviewing the P6SMB200A-E3/5B datasheet, P6SMB200A-E3/5B pinout, P6SMB200A-E3/5B application, or P6SMB200A-E3/5B equivalent, this page provides verified electrical parameters, thermal derating behavior, RoHS-compliant packaging details, and validated alternative parts for ESD and surge protection design-in.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche response. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) requires PCB copper pad thermal management per the 0.2" × 0.2" (5.0 mm × 5.0 mm) mounting recommendation to sustain repetitive 600 W pulses at 0.01% duty cycle.
The device exhibits 1.0 μA maximum reverse leakage (ID) at 171 V standoff and a 0.108 %/°C temperature coefficient of VBR, enabling predictable clamping performance across -65 °C to +150 °C operating junction range. It meets J-STD-020 MSL Level 1 and is RoHS-compliant per base suffix -E3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min) | 190 V - Minimum breakdown voltage at 1.0 mA test current; ensures reliable turn-on during transients exceeding system rail tolerance. |
| VC @ IPPM | 274 V - Clamped voltage at 2.2 A peak pulse current (10/1000 μs); determines maximum stress imposed on protected downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; supports robust protection against IEC 61000-4-5 Level 4 surges when properly mounted. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; mandates use of ≥5.0 mm × 5.0 mm copper pads per terminal for sustained pulse operation. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); validates compatibility with inrush-limited power supply inputs. |
| TJ max | +150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments with proper thermal design. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant (-E3), MSL Level 1, UL 94 V-0 molding compound. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VWM (171 V), identical SMB package, but higher VC = 324 V at 1.8 A; lower IPPM rating. | Less effective clamping margin for 3.3 V or 5 V logic interfaces downstream of protected rail. | Select when cost sensitivity outweighs clamping voltage optimization and layout allows minor derating. |
| 1.5SMC200A | Higher package thermal mass (SMC/DO-214AB), same VWM/VC, but RθJA = 40 °C/W - better thermal handling at same power level. | Requires larger PCB footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm); unsuitable for space-constrained modules. | Choose for high-reliability industrial systems needing extended pulse endurance without thermal pad redesign. |
Compared with P6SMB200A-E3/5B, SMBJ200A offers lower cost but sacrifices clamping performance, while 1.5SMC200A improves thermal robustness at the expense of board area - making P6SMB200A-E3/5B optimal for compact, thermally managed 200 V rail protection.

FAQ
What is the maximum clamping voltage of the P6SMB200A-E3/5B under standard test conditions?
The P6SMB200A-E3/5B has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at 2.2 A peak pulse current (IPPM). This value is measured at TA = 25 °C with terminals mounted on 0.2" × 0.2" copper pads. The clamping voltage defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings. P6SMB200A-E3/5B maintains this specification across its full operating temperature range.
Is the P6SMB200A-E3/5B suitable for automotive applications requiring AEC-Q101 qualification?
No, the P6SMB200A-E3/5B is not AEC-Q101 qualified. Its -E3 suffix denotes RoHS-compliant commercial-grade construction. For automotive use, Vishay specifies AEC-Q101 variants with suffixes such as -HE3_B (e.g., P6SMB200AHE3_B), which include additional qualification testing per AEC-Q101 Rev D. P6SMB200A-E3/5B may be used in non-safety-critical automotive subsystems only after full system-level validation, but it does not carry the automotive qualification designation. Always verify qualification status via the full ordering code.
How does the thermal resistance of the P6SMB200A-E3/5B affect PCB layout requirements?
The P6SMB200A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, which necessitates adherence to the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per terminal to achieve rated 600 W pulse performance. Reducing pad size increases thermal impedance, causing junction temperature to rise faster during repetitive surges and potentially degrading clamping consistency or accelerating wear-out. P6SMB200A-E3/5B must be placed with unobstructed copper area and no thermal relief spokes to maintain thermal integrity.
What is the reverse leakage current specification for the P6SMB200A-E3/5B at its rated standoff voltage?
At its maximum reverse standoff voltage (VWM) of 171 V and TA = 25 °C, the P6SMB200A-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss and negligible impact on system quiescent current, especially critical in battery-powered or energy-harvesting applications. Leakage remains below 10 μA up to 150 °C junction temperature, supporting reliable operation in high-temperature environments without compromising standby efficiency. P6SMB200A-E3/5B meets this spec across its full temperature range.
Can the P6SMB200A-E3/5B be used in bidirectional transient protection configurations?
No, the P6SMB200A-E3/5B is a unidirectional TVS diode, identifiable by its cathode band marking and specified parameters (VWM, VBR, VC) for reverse-biased operation only. Bidirectional protection requires a part with "CA" suffix (e.g., P6SMB200CA), which provides symmetrical clamping in both polarities. Using P6SMB200A-E3/5B in AC or floating signal lines risks forward conduction and failure during negative transients. Always match device polarity to circuit topology - P6SMB200A-E3/5B is strictly for DC rail protection with defined ground reference.
