Product details
Overview
P6SMB150AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 207 A peak pulse current (IPPM) at 10/1000 μs, and 600 W peak pulse power (PPPM). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial power supplies and automotive control units.
For engineers reviewing the P6SMB150AHE3_A/I datasheet, P6SMB150AHE3_A/I pinout, P6SMB150AHE3_A/I application, or P6SMB150AHE3_A/I equivalent, key selection criteria include clamping voltage (VC = 207 V), AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and MSL Level 1 moisture sensitivity rating for lead-free reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1.0 μA reverse leakage at 128 V), then rapidly avalanches below its 143–158 V breakdown threshold (VBR at 1 mA) to limit transient overvoltage. Its low incremental surge resistance ensures stable clamping during repetitive 0.01% duty cycle pulses.
Designed for PCB-level ESD and surge protection, it features glass-passivated junctions, matte tin-plated leads compliant with J-STD-002, and thermal resistance of 100 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads. The device is qualified per AEC-Q101 and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature triggering. |
| VC (Clamping Voltage) | 207 V at 207 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability for standardized 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| IPPM (Peak Pulse Current) | 207 A - Maximum non-repetitive surge current the device can safely divert without degradation; validated per Fig. 1 and Fig. 3. |
| TJmax | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments with derating above 25 °C. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by a single band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to system ground or low-side reference in unidirectional clamp configuration; not used for reverse surge suppression. |
| Cathode | Current exit terminal during reverse avalanche | Connected to protected line (e.g., power rail or signal trace); conducts surge current to ground when VLINE exceeds VC. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - enables use in engine control modules and ADAS sensors. |

Use Value: 150 °C max junction temperature and 100 °C/W RθJA allow reliable operation in sealed enclosures; AEC-Q101 qualification adds confidence for extended field life. |
Use Scenario: Board-level protection for USB 2.0 data lines and VBUS in smart home hubs and gaming peripherals. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS rail only (not data lines); clamps hot-swap inrush and adapter fault transients before they reach USB controller ICs. Use Value: SMB package enables compact placement near connector; 207 V clamping safely contains 120 VAC fault propagation while maintaining 5 V nominal operation margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/5B | Same VWM (128 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select when board space is constrained and surge threat level is limited to ESD/EFT only. |
| 1.5SMC150A | Same electrical specs but SMC (DO-214AB) package - larger footprint (0.285" × 0.185"), higher IPPM margin (220 A), RθJA = 70 °C/W | Better thermal performance for high-duty-cycle environments; requires more PCB area and different stencil design. | Choose for industrial motor drives where sustained surge repetition occurs and thermal management is critical. |
Compared with SMAJ150A-E3/5B and 1.5SMC150A, the P6SMB150AHE3_A/I delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, and SMB footprint - making it preferred for space-constrained automotive and telecom designs requiring certified reliability and standardized reflow compatibility.

FAQ
What is the clamping voltage of the P6SMB150AHE3_A/I under a 10/1000 μs surge?
The P6SMB150AHE3_A/I has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 207 A using the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and represents the upper voltage limit imposed on the protected circuit during worst-case transient events. The P6SMB150AHE3_A/I maintains this clamping performance across its specified operating temperature range.
Is the P6SMB150AHE3_A/I qualified for automotive applications?
Yes, the P6SMB150AHE3_A/I carries the HE3 suffix indicating RoHS-compliant construction and full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JS-001, making it suitable for under-hood and cabin-mounted automotive electronics such as body control modules and ADAS sensor interfaces. The P6SMB150AHE3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "_A/I" suffix mean in P6SMB150AHE3_A/I?
The "_A/I" suffix in P6SMB150AHE3_A/I denotes packaging configuration: "A" indicates the device is unidirectional, and "I" specifies 13-inch diameter plastic tape and reel delivery containing 3200 units. This format aligns with Vishay's ordering nomenclature in Document Number 88370, Section "ORDERING INFORMATION", where "/I" consistently identifies the 13" reel option for HE3-grade parts.
How does the P6SMB150AHE3_A/I compare to bidirectional TVS diodes like P6SMB150CA?
The P6SMB150AHE3_A/I is unidirectional and features a cathode band for polarity identification, whereas P6SMB150CA is bidirectional with no polarity marking and symmetrical breakdown in both directions. Electrically, the P6SMB150AHE3_A/I has identical VWM, VBR, and VC ratings as its bidirectional counterpart but is intended for DC-biased rails where reverse conduction must be blocked. The P6SMB150AHE3_A/I cannot substitute for P6SMB150CA in AC-coupled or floating signal line applications.
What is the maximum printed circuit board pad size recommended for thermal performance of the P6SMB150AHE3_A/I?
Vishay specifies a minimum mounting pad layout of 0.2" × 0.2" (5.0 mm × 5.0 mm) copper areas per terminal for the P6SMB150AHE3_A/I to achieve the published thermal resistance (RθJA = 100 °C/W) and peak pulse ratings. Reducing pad size below this degrades power dissipation capability and may cause premature failure during repetitive surges. The P6SMB150AHE3_A/I datasheet Figure 2 provides derating curves confirming this requirement.
