Product details
Overview
P6SMB13AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping transient overvoltages on power and signal lines. It features a 11.1 V stand-off voltage (VWM), 12.4–13.7 V breakdown voltage (VBR) at 1 mA, 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB13AHE3_B/I datasheet, P6SMB13AHE3_B/I pinout, P6SMB13AHE3_B/I application, or P6SMB13AHE3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), polarity marking convention, and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (Rev. 09-Jan-2024, Doc. #88370).
Technical Context
The P6SMB13AHE3_B/I operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<5 μA at VWM), while the low incremental surge resistance enables rapid energy absorption during ESD or load-switching transients.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak. The "HE3" suffix confirms RoHS-compliance and AEC-Q101 qualification; "_B/I" denotes 13" tape-and-reel packaging (3200 units) with halogen-free molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown) | 12.4–13.7 V at 1 mA - Confirmed avalanche conduction range; ensures predictable turn-on under transient stress. |
| VC (Clamping) | 18.2 V at 33.0 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; limits downstream device stress. |
| PPPM | 600 W - Sustained transient energy handling capability; validated for repetitive 0.01 % duty cycle pulses. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area for thermal management at 5.0 W steady-state dissipation. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-temperature industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity marked by cathode band; anode and cathode terminals are axially oriented along the body length.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5B | Same VWM/VBR/VC, but SMA package (higher RθJA = 140 °C/W); lower PPPM (400 W). | Limited to lower-energy transients; unsuitable for automotive load-dump where 600 W is mandated. | Select P6SMB13AHE3_B/I when 600 W surge rating and AEC-Q101 qualification are required. |
| 1.5SMC13A | Same electrical specs, but larger SMC (DO-214AB) package; higher thermal mass but less board space efficiency. | Used where board layout allows larger footprint and higher steady-state power handling is needed. | Choose P6SMB13AHE3_B/I for space-constrained automotive modules requiring SMB footprint and AEC-Q101 compliance. |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHE3_B/I uniquely combines 600 W surge capability, AEC-Q101 qualification, and SMB footprint - making it the optimal choice for automotive and high-reliability industrial designs where both performance density and qualification rigor are mandatory.

FAQ
What is the clamping voltage of the P6SMB13AHE3_B/I under a 10/1000 μs surge?
The P6SMB13AHE3_B/I has a maximum clamping voltage (VC) of 18.2 V when subjected to a 33.0 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6SMB13AHE3_B/I maintains this clamping performance across its qualified operating temperature range.
Is the P6SMB13AHE3_B/I AEC-Q101 qualified?
Yes, the P6SMB13AHE3_B/I is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant construction with full AEC-Q101 stress testing, including temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness validation. This qualification makes the P6SMB13AHE3_B/I suitable for automotive powertrain, chassis, and body electronics where reliability under harsh environmental conditions is mandatory.
What does the "_B/I" suffix mean in P6SMB13AHE3_B/I?
The "_B/I" suffix in P6SMB13AHE3_B/I indicates two specific attributes: "_B" denotes AEC-Q101 qualification for the P6SMB6.8A–P6SMB220A voltage range, and "/I" specifies packaging in 13-inch diameter plastic tape-and-reel format containing 3200 units. This packaging supports high-volume automated SMT placement and aligns with IPC-7351 land pattern recommendations for SMB (DO-214AA) devices.
How does the P6SMB13AHE3_B/I differ from bidirectional variants like P6SMB13CA?
The P6SMB13AHE3_B/I is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current beyond ~3.5 V (VF at 50 A). In contrast, P6SMB13CA is bidirectional with symmetrical clamping in both polarities - suited for AC signal lines or differential buses. The P6SMB13AHE3_B/I's cathode band marking and single-direction behavior make it ideal for DC power rail protection where polarity is fixed and forward conduction must be avoided.
What is the thermal resistance of the P6SMB13AHE3_B/I, and how does it affect PCB layout?
The P6SMB13AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C at 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid thermal bottlenecks - especially in automotive applications where ambient temperatures exceed 85 °C. The P6SMB13AHE3_B/I's low RθJL (20 °C/W) further emphasizes the importance of solid thermal vias to internal ground planes.
