Product details
Overview
P6SMB11AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 11 V breakdown voltage (VBR min/max = 10.5–11.6 V at 1 mA), 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive-grade power rail protection for ECUs and sensor interfaces.
For engineers reviewing the P6SMB11AHM3_A/I datasheet, P6SMB11AHM3_A/I pinout, P6SMB11AHM3_A/I application, or P6SMB11AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuit nodes, activating when reverse voltage exceeds VWM (9.4 V) to divert transient energy away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5 μA at VWM).
The device delivers 600 W peak pulse power handling with 10/1000 μs waveform, supports 100 A non-repetitive forward surge current (IFSM), and maintains operation across -65 °C to +150 °C junction temperature range. Thermal resistance is RθJA = 100 °C/W (typ.) on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1 mA test current - defines precise voltage threshold where clamping begins |

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 VBR (10.5–11.6 V), but 400 W PPPM, SMA package (DO-214AC), non-AEC-Q101 | Limited to commercial-grade industrial or consumer use; lower surge margin and no automotive qualification | Select when cost-sensitive non-automotive designs require footprint compatibility with SMA layout |
| 1.5SMC11A | Same electrical specs, but SMC (DO-214AB) package - larger footprint, higher RθJA (75 °C/W), same AEC-Q101 HM3 variant available | Requires PCB redesign; better thermal dissipation but less space-efficient than SMB | Choose when higher thermal margin is needed and board area permits SMC footprint |
Compared with SMAJ11A-E3/5B and 1.5SMC11A, the P6SMB11AHM3_A/I offers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and compact SMB packaging - making it the preferred choice for space-constrained automotive and industrial modules requiring validated reliability.

FAQ
What is the clamping voltage of the P6SMB11AHM3_A/I under full 600 W surge conditions?
The P6SMB11AHM3_A/I clamps to a maximum of 15.6 V when subjected to its rated 38.5 A peak pulse current (10/1000 μs waveform), which corresponds to the full 600 W peak pulse power. This value is measured per Figure 1 in the official Vishay datasheet (Doc. #88370) and represents the worst-case voltage imposed on protected circuitry during standardized surge events.
Is the P6SMB11AHM3_A/I suitable for bidirectional transient protection?
No, the P6SMB11AHM3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies part numbers ending in "CA" (e.g., P6SMB11CA). Using P6SMB11AHM3_A/I in bidirectional configurations risks failure during positive-going transients on the anode side.
Does the P6SMB11AHM3_A/I meet AEC-Q101 requirements, and what does the "HM3" suffix signify?
Yes, the "HM3" suffix in P6SMB11AHM3_A/I confirms halogen-free, RoHS-compliant construction and full AEC-Q101 qualification per revision B of the standard. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - validating suitability for automotive powertrain and chassis applications.
What is the maximum steady-state power dissipation for the P6SMB11AHM3_A/I?
The P6SMB11AHM3_A/I has a maximum steady-state power dissipation (PD) of 5.0 W at TA = 50 °C with infinite heatsink conditions. In typical PCB layouts using 0.2" × 0.2" copper pads per terminal, derating applies above 25 °C ambient per Figure 2 in the datasheet, limiting continuous dissipation to ~2.5 W at 85 °C ambient.
How does the P6SMB11AHM3_A/I compare to older P6SMB11A variants in terms of reliability and packaging?
The P6SMB11AHM3_A/I improves upon legacy P6SMB11A parts with halogen-free molding compound, MSL Level 1 moisture sensitivity rating (peak reflow 260 °C), and AEC-Q101 qualification. The "HM3" suffix denotes both environmental compliance and automotive reliability validation - whereas base P6SMB11A variants lack these certifications and may use brominated flame retardants.
