Product details
Overview
P6SMB11AHE3_B/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 9.4 V stand-off voltage (VWM), 10.5–11.6 V breakdown voltage (VBR) at 1 mA, 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial electronics.
For engineers reviewing the P6SMB11AHE3_B/H datasheet, P6SMB11AHE3_B/H pinout, P6SMB11AHE3_B/H application, or P6SMB11AHE3_B/H equivalent, this AEC-Q101 qualified device offers verified transient suppression performance, RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and validated thermal resistance (RθJA = 100 °C/W) for reliable board-level surge protection design.
Technical Context
The P6SMB11AHE3_B/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (VBR = 10.5–11.6 V). Its low clamping voltage (VC = 15.6 V at IPPM) ensures downstream components remain below safe operating limits during ESD or inductive switching events.
It delivers 600 W peak pulse power handling per 10/1000 μs waveform with 0.01 % duty cycle, supported by 100 °C/W junction-to-ambient thermal resistance and 20 °C/W junction-to-lead resistance. The device is rated for TJ = –65 to +150 °C and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 9.4 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown) | 10.5–11.6 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients |
| VC (Clamping) | 15.6 V at 38.5 A - Measured voltage across device during 10/1000 μs surge; protects 12 V rail ICs from overvoltage |

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, 400 W PPPM, SMA package (larger RθJA) | Lower surge rating and higher clamping voltage reduce margin for 12 V systems with tight voltage tolerances | Select when cost sensitivity outweighs clamping performance; verify thermal derating for same PCB layout |
| 1.5SMC11A | Same VWM/VC specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W, higher IFSM (200 A) | Better thermal performance supports higher repetition rates but requires larger board area | Prefer for high-duty-cycle industrial environments where sustained surge energy exceeds SMB limits |
Compared with SMAJ11A-E3/5B and 1.5SMC11A, P6SMB11AHE3_B/H provides optimal balance of compact SMB footprint, AEC-Q101 qualification, and low 15.6 V clamping - making it preferred for space-constrained automotive and industrial PCBs requiring certified reliability.

FAQ
What is the clamping voltage of P6SMB11AHE3_B/H at its rated peak pulse current?
The P6SMB11AHE3_B/H has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current (IPPM) of 38.5 A under the standard 10/1000 μs waveform. This value is measured per test conditions defined in the Vishay datasheet (Document Number: 88370) and ensures protected circuitry remains within safe operating limits during surge events. The P6SMB11AHE3_B/H maintains this clamping performance across its qualified temperature range.
Is P6SMB11AHE3_B/H suitable for automotive applications?
Yes, P6SMB11AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" and "_B" suffixes in its ordering code. It meets stringent requirements for temperature cycling, humidity resistance, and mechanical shock, and is rated for operation from –65 °C to +150 °C junction temperature. The P6SMB11AHE3_B/H is commonly deployed in engine control modules, body control units, and ADAS sensor interfaces where certified reliability is mandatory.
What does the "_B/H" suffix indicate in P6SMB11AHE3_B/H?
The "_B" suffix denotes AEC-Q101 qualification for the P6SMB11AHE3_B/H series, while "/H" specifies packaging in 7-inch plastic tape-and-reel format with 750 units per reel. This ordering code aligns with Vishay's standardized nomenclature for automotive-grade, RoHS-compliant TVS diodes in SMB package. The P6SMB11AHE3_B/H is not a sample or evaluation variant - it is a fully qualified production part with traceable lot documentation.
How does P6SMB11AHE3_B/H compare to bidirectional variants like P6SMB11CA?
P6SMB11AHE3_B/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where current flows in one direction. In contrast, P6SMB11CA is bidirectional and symmetrical - suitable for AC or differential signal lines. The P6SMB11AHE3_B/H offers tighter leakage control (5.0 μA max at VWM) and is optimized for 12 V rail clamping, whereas P6SMB11CA exhibits identical VBR in both directions but higher ID in low-VWM versions. Selection depends strictly on circuit topology and polarity requirements.
What is the thermal resistance of P6SMB11AHE3_B/H, and how does it affect PCB layout?
The P6SMB11AHE3_B/H 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. This value assumes minimum recommended pad layout per Vishay's package drawing. To maintain safe junction temperatures during repetitive surges, designers must ensure adequate copper area and avoid excessive trace length between the P6SMB11AHE3_B/H and ground/power planes. Derating curves in Figure 2 of the datasheet guide thermal design at elevated ambient temperatures.
