Product details
Overview
P6SMB10AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM = 8.55 V), 14.5 V clamping voltage at 41.4 A peak pulse current (10/1000 μs), and 600 W peak pulse power. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power supplies.
For engineers reviewing the P6SMB10AHM3_A/H datasheet, P6SMB10AHM3_A/H pinout, P6SMB10AHM3_A/H application, or P6SMB10AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), 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 clamping device that enters avalanche breakdown when reverse voltage exceeds its 9.5–10.5 V breakdown range (VBR at 1 mA), limiting transient energy to safe levels for downstream circuitry. Its glass-passivated junction ensures stable leakage (<10 μA at VWM) and fast response time (<1 ns).
The device is thermally optimized for SMB package constraints: RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to 150 °C junction temperature under repetitive 0.01% duty cycle pulses. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin. |
| VBR (Breakdown) | 9.5–10.5 V at 1 mA - Avalanche onset threshold; ensures predictable turn-on during transients. |
| VC (Clamping) | 14.5 V at IPPM = 41.4 A (10/1000 μs) - Peak voltage seen by protected circuit; determines minimum IC withstand rating. |
| PPPM | 600 W - Peak transient energy absorption capability; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | ≤10 μA at VWM - Low reverse leakage preserves power efficiency and avoids false triggering in high-impedance nodes. |
| TJ max | 150 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with J-STD-020 MSL level 1 reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential rail in unidirectional configuration; carries forward surge current up to 100 A (8.3 ms half-sine). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or sensor input); initiates avalanche conduction when transient exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3) | Validated for automotive applications including engine control units and ADAS sensors; supports 150 °C operation and thermal cycling. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 combination wave surges (4 kV/2 Ω) without degradation; enables single-device protection for 12 V/24 V systems. |
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature; eliminates risk of junction corrosion in humid or chemically aggressive environments. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs; critical for safeguarding 12 V-rated CAN transceivers and microcontrollers. |
| MSL level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking; reduces manufacturing complexity and cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5B | Same SMB package, 10 V VWM, but rated for 400 W PPPM (vs. 600 W); no AEC-Q101 qualification. | Limited to commercial-grade consumer/industrial use; not suitable for automotive under-hood deployment. | Select when cost sensitivity outweighs automotive qualification and higher surge margin. |
| 1.5SMC10A | Higher-power SMC package (same VWM), 1500 W PPPM, larger footprint (0.320" × 0.230"), RθJA = 30 °C/W. | Used where PCB space allows and higher single-event surge immunity is required (e.g., AC mains interfaces). | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and thermal derating is less constrained. |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, P6SMB10AHM3_A/H uniquely balances AEC-Q101 compliance, 600 W surge capacity, and SMB footprint-making it optimal for space-constrained automotive modules requiring validated reliability without board redesign.

FAQ
What is the maximum clamping voltage of the P6SMB10AHM3_A/H under standard test conditions?
The P6SMB10AHM3_A/H has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 41.4 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB10AHM3_A/H maintains this clamping performance across its specified operating temperature range, supporting design margin calculations for downstream ICs rated to 16 V.
Is the P6SMB10AHM3_A/H qualified for automotive applications?
Yes, the P6SMB10AHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix in its part number. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-ensuring suitability for automotive powertrain, body electronics, and ADAS subsystems. The P6SMB10AHM3_A/H operates reliably from −65 °C to +150 °C junction temperature, meeting under-hood environmental requirements.
How does the P6SMB10AHM3_A/H differ from bidirectional variants like P6SMB10CA?
The P6SMB10AHM3_A/H is unidirectional, featuring a cathode band marking and conducting only in reverse breakdown, whereas P6SMB10CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. The P6SMB10AHM3_A/H offers lower leakage (<10 μA at VWM) and is preferred for DC power rail protection, while P6SMB10CA suits AC-coupled signal lines or differential buses where polarity reversal occurs. Both share identical PPPM (600 W) and SMB packaging.
What is the thermal resistance specification for the P6SMB10AHM3_A/H?
The P6SMB10AHM3_A/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, and a junction-to-lead resistance (RθJL) of 20 °C/W. These values define thermal derating behavior: at 125 °C ambient, the device's power dissipation must be reduced to ~2.5 W to maintain TJ ≤ 150 °C. The P6SMB10AHM3_A/H's thermal profile supports high-density layouts without forced cooling in most automotive and industrial applications.
Can the P6SMB10AHM3_A/H replace older P6SMB10A variants in existing designs?
Yes, the P6SMB10AHM3_A/H is a direct replacement for legacy P6SMB10A parts in terms of electrical specs, package dimensions, and pinout-while adding halogen-free construction and AEC-Q101 qualification. Its SMB (DO-214AA) footprint, cathode-band polarity, and 8.55 V VWM match prior versions exactly. The P6SMB10AHM3_A/H requires no PCB changes and improves long-term reliability for new production runs targeting automotive or green compliance standards.
