Product details
Overview
P6SMB16AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM = 13.6 V), 22.5 V clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform. It provides robust ESD and surge protection for DC power rails and signal lines in automotive-grade industrial electronics.
For engineers reviewing the P6SMB16AHE3_B/I datasheet, P6SMB16AHE3_B/I pinout, P6SMB16AHE3_B/I application, or P6SMB16AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low 1.0 μA reverse leakage at VWM, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable breakdown behavior and fast sub-nanosecond response to transients. Its thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W support reliable operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
The device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification; the "_B" revision denotes automotive-grade variant availability for P6SMB6.8A–P6SMB220A series.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse operating voltage before clamping begins; ensures no conduction during normal 12 V system operation. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1.0 mA test current - Tight 10% tolerance defines precise clamping onset threshold for predictable protection margin. |
| VC (Clamping Voltage) | 22.5 V at 26.7 A IPPM - Limits transient voltage seen by downstream ICs to safe levels during 600 W surge events. |
| IPPM (Peak Pulse Current) | 26.7 A with 10/1000 μs waveform - Sustains high-energy surges common in automotive load-dump and inductive switching scenarios. |
| TJmax | 150 °C - Enables reliable operation in under-hood and industrial environments without derating below ambient 125 °C. |
| Package | SMB (DO-214AA) - Low-profile 3.94 mm × 2.20 mm surface-mount package compatible with high-speed pick-and-place and reflow processes. |
| Qualification | AEC-Q101 qualified - Validated for automotive electronic systems requiring zero-failure reliability over extended temperature and lifetime cycles. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band on one end; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to lower-potential side of protected circuit | Must be tied to ground or return path to enable clamping action when transient exceeds VWM. |
| Cathode | Current exit terminal during reverse clamping; marked with band | Connected to protected line (e.g., 12 V rail); conducts surge current to ground when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation. |
| AEC-Q101 qualification (HE3_B) | Validated for automotive use including engine control units, body electronics, and ADAS sensors. |
| Glass passivated junction | Ensures stable VBR and low leakage (<1.0 μA) across temperature and lifetime. |
| MSL Level 1, 260 °C reflow compatible | Supports single-pass lead-free reflow without moisture-related popcorning or delamination. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD >15 kV). |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5B | Same VWM (13.6 V), identical SMB package, but only commercial-grade (not AEC-Q101 qualified); 22.5 V VC at 26.7 A. | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 is not mandated. | Select SMAJ16A-E3/5B for cost-sensitive non-automotive designs requiring same electrical performance without qualification overhead. |
| 1.5SMC16A | Higher package thermal resistance (RθJA ≈ 125 °C/W vs. 100 °C/W); same VWM/VC specs but SMC (DO-214AB) package (larger footprint: 6.2 mm × 4.6 mm). | Requires larger PCB area and may limit layout density; not optimized for high-density automotive modules. | Choose 1.5SMC16A only if existing board uses SMC footprint or requires higher thermal mass for infrequent high-duty-cycle surges. |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, P6SMB16AHE3_B/I uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and verified 150 °C operation-making it the preferred choice for space-constrained automotive and industrial designs demanding certified reliability.

FAQ
What is the maximum clamping voltage of P6SMB16AHE3_B/I at its rated peak pulse current?
The P6SMB16AHE3_B/I has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured under the standardized 10/1000 μs double-exponential surge waveform. This value ensures downstream components see limited overvoltage during surge events, and is confirmed in the Vishay P6SMB datasheet revision 09-Jan-2024, page 2, Electrical Characteristics table for P6SMB16A.
Is P6SMB16AHE3_B/I suitable for automotive applications?
Yes, P6SMB16AHE3_B/I is explicitly AEC-Q101 qualified, as indicated by the "HE3_B" suffix per Vishay's ordering information (page 3). It is designed for automotive power rail and signal line protection, supporting junction temperatures up to 150 °C and validated for reliability under temperature cycling, humidity, and mechanical stress per AEC-Q101 requirements.
What does the "_B/I" suffix mean in P6SMB16AHE3_B/I?
The "_B" denotes the AEC-Q101 qualified revision level for the P6SMB6.8A–P6SMB220A family, while "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format aligns with Vishay's ordering convention shown on page 3 of document 88370, confirming full traceability and automated assembly readiness for P6SMB16AHE3_B/I.
How does P6SMB16AHE3_B/I differ from the standard P6SMB16A-E3?
P6SMB16AHE3_B/I adds AEC-Q101 qualification and enhanced process controls beyond the commercial-grade P6SMB16A-E3, which carries only RoHS compliance. Both share identical electrical specs (VWM = 13.6 V, VC = 22.5 V), but P6SMB16AHE3_B/I undergoes additional automotive stress testing and lot traceability-critical for Tier 1 automotive suppliers requiring PPAP documentation.
What is the thermal resistance of P6SMB16AHE3_B/I, and how does it affect PCB layout?
P6SMB16AHE3_B/I 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, as specified on page 3 of the datasheet. To maintain safe junction temperature under repetitive surges, designers must adhere to this pad layout-reducing pad size increases RθJA and risks thermal runaway during sustained transient activity.
