Product details
Overview
P6SMB11AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 11 V breakdown voltage (VBR = 10.5–11.6 V at IT = 1.0 mA), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power electronics.
For engineers reviewing the P6SMB11AHM3_B/I datasheet, P6SMB11AHM3_B/I pinout, P6SMB11AHM3_B/I application, or P6SMB11AHM3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMB package mechanical data, clamping performance under surge conditions, and direct alternatives with documented differences in breakdown tolerance and temperature coefficient.
Technical Context
The P6SMB11AHM3_B/I operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified VBR range (10.5–11.6 V), with fast response time (<1 ns) and low incremental surge resistance enabling effective transient suppression. Its glass-passivated junction ensures stable leakage and long-term reliability under repetitive surges.
Designed for surface-mount assembly on standard PCB pads (0.2" × 0.2"), it meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C), supports 100 A non-repetitive forward surge (8.3 ms half-sine), and features matte tin-plated leads compliant with JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5B | VBR = 11.1–12.3 V; VC = 17.0 V at 35.3 A; not AEC-Q101 qualified | Commercial-grade only; higher clamping voltage reduces margin for 3.3 V logic protection | Select when AEC-Q101 is not required and cost is prioritized over automotive qualification |
| 1.5SMC11A | VBR = 10.5–11.6 V (same); VC = 18.2 V at 33.0 A; larger SMC (DO-214AB) package | Higher thermal mass but requires larger PCB footprint; no halogen-free option available | Choose for higher surge repetition rates where SMB thermal resistance (100 °C/W) may limit duty cycle |
Compared with SMAJ11A-E3/5B and 1.5SMC11A, the P6SMB11AHM3_B/I uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized 15.6 V clamping in the compact SMB footprint-making it the preferred choice for space-constrained automotive and industrial designs requiring certified reliability.

FAQ
What is the breakdown voltage tolerance of P6SMB11AHM3_B/I?
The P6SMB11AHM3_B/I has a guaranteed breakdown voltage range of 10.5 V to 11.6 V at 1.0 mA test current, corresponding to ±5% tolerance around the nominal 11 V rating. This tight VBR window ensures consistent clamping behavior across production lots and enables precise coordination with system overvoltage thresholds. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 09-Jan-2024.
Is P6SMB11AHM3_B/I suitable for automotive applications?
Yes, P6SMB11AHM3_B/I is AEC-Q101 qualified, as indicated by the "HM3_B" suffix per Vishay's ordering information. It is explicitly rated for automotive use including engine control, body electronics, and ADAS sensor interfaces. The device meets MSL Level 1, operates from −65 °C to +150 °C, and is halogen-free and RoHS-compliant-fulfilling key requirements for modern automotive electronics.
What is the maximum clamping voltage of P6SMB11AHM3_B/I under surge conditions?
The P6SMB11AHM3_B/I exhibits a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A (10/1000 μs waveform). This value is measured at TA = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads). It represents the highest voltage seen across the device during transient suppression, directly protecting downstream 3.3 V or 5 V ICs from overvoltage stress.
Does P6SMB11AHM3_B/I have a bidirectional variant?
No, P6SMB11AHM3_B/I is strictly unidirectional, as confirmed by its "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB11CA). The unidirectional configuration provides lower leakage and tighter VBR control, making P6SMB11AHM3_B/I optimal for DC power rail and signal-line protection where polarity is fixed and reverse conduction must be blocked.
What is the thermal resistance of P6SMB11AHM3_B/I?
The P6SMB11AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. Its junction-to-lead resistance (RθJL) is 20 °C/W. These values define power derating curves above 25 °C ambient and confirm suitability for high-surge-density applications where localized heating must be managed without heatsinking.
