Product details
Overview
P6SMB11AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 9.40 V stand-off voltage (VWM), 10.5–11.6 V breakdown voltage (VBR) at 1 mA test current, 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial electronics.
For engineers reviewing the P6SMB11AHE3_A/H datasheet, P6SMB11AHE3_A/H pinout, P6SMB11AHE3_A/H application, or P6SMB11AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 10.5–11.6 V). Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the SMB package provides mechanical robustness and thermal dissipation via soldered leads.
The device is rated for 600 W peak pulse power (10/1000 μs), 5.0 W steady-state power dissipation at 50 °C, and supports repetitive surge events at 0.01 % duty cycle. It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive use - confirmed by the "HE3" suffix and revision "A/H" marking.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5B | Same VWM (9.4 V), VC = 18.2 V at 33.0 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required. | Select if board space is constrained and surge threat level is Class 3 (IEC 61000-4-5) or lower. |
| 1.5SMC11A | Same VWM/VC specs but in larger SMC (DO-214AB) package; RθJL = 10 °C/W vs. 20 °C/W for SMB; higher IFSM (200 A). | Better thermal performance under repeated surges; requires larger PCB pad area and may not fit dense automotive modules. | Prefer for industrial motor drives with frequent inductive switching where thermal recovery matters more than size. |
Compared with SMAJ11A-E3/5B and 1.5SMC11A, P6SMB11AHE3_A/H delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, and SMB footprint - making it the preferred choice for space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the maximum clamping voltage of the P6SMB11AHE3_A/H under a 10/1000 μs surge?
The P6SMB11AHE3_A/H has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A using the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB11AHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is the P6SMB11AHE3_A/H qualified for automotive applications?
Yes, the P6SMB11AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and revision code "A/H" in its ordering designation. It undergoes stress testing for temperature cycling, humidity bias, and surge endurance per AEC-Q101 requirements, making it suitable for automotive powertrain, body electronics, and ADAS subsystems. The P6SMB11AHE3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "HE3" suffix indicate in P6SMB11AHE3_A/H?
The "HE3" suffix in P6SMB11AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants like "E3". The "H" in the revision code indicates 7" tape-and-reel packaging (750 units per reel), while "A" specifies the revision level per Vishay's internal documentation. The P6SMB11AHE3_A/H meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.
How does the P6SMB11AHE3_A/H compare to bidirectional TVS diodes like P6SMB11CA?
The P6SMB11AHE3_A/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply rails), whereas P6SMB11CA is bidirectional and suited for AC or floating signal lines. The P6SMB11AHE3_A/H exhibits forward conduction capability (IFSM = 100 A) and lower leakage at VWM, while P6SMB11CA has symmetric clamping in both directions but no forward surge rating. Use P6SMB11AHE3_A/H when protecting polarized power paths.
What is the thermal resistance from junction to ambient for the P6SMB11AHE3_A/H?
The P6SMB11AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay Document 88370. This value assumes still air conditions and defines the temperature rise above ambient per watt of steady-state power dissipation. For higher-power or high-ambient applications, thermal design must account for this RθJA to maintain TJ ≤ 150 °C.
