Product details
Overview
P6SMB10AHM3/I 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 41.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB10AHM3/I datasheet, P6SMB10AHM3/I pinout, P6SMB10AHM3/I application, or P6SMB10AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that conducts above its breakdown voltage (VBR = 9.5–10.5 V at 1 mA) to divert transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable leakage performance (<10 μA at VWM) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
The P6SMB10AHM3/I is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and supports operation from −65 °C to +150 °C junction temperature. Its halogen-free, RoHS-compliant construction and MSL Level 1 moisture sensitivity rating enable lead-free reflow compatibility up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum reverse voltage before significant conduction; defines safe operating range for normal circuit conditions. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Voltage at which device enters avalanche breakdown; ensures precise clamping onset. |
| VC (Clamping Voltage) | 14.5 V at 41.4 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capability under standardized surge; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) compliance. |
| IPPM (Peak Pulse Current) | 41.4 A - Peak current the device safely shunts during 10/1000 μs waveform; determines minimum trace width and PCB layout robustness. |
| TJmax | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal derating. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires ≥5.0 mm × 5.0 mm copper pad per terminal for full power rating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 10 V VWM, but lower PPPM = 400 W and higher VC = 16.7 V at 24.2 A. | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); not suitable for ISO 7637-2 pulse 5a. | Select when cost sensitivity outweighs surge energy requirements and AEC-Q101 is not mandated. |
| 1.5SMC10A | Higher-power SMC package (1500 W), same VWM/VBR, but larger footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm). | Used where board space allows and higher single-event energy handling (e.g., 12 V battery rail) is required. | Choose only if PCB layout permits larger SMC footprint and system-level testing confirms need for >600 W rating. |
Compared with SMAJ10A and 1.5SMC10A, the P6SMB10AHM3/I delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and compact SMB footprint - making it preferred for space-constrained automotive and industrial modules requiring production-grade reliability.

FAQ
What is the polarity configuration of the P6SMB10AHM3/I?
The P6SMB10AHM3/I is a unidirectional TVS diode, with the banded end indicating the cathode terminal. This configuration allows it to block reverse voltage up to 8.55 V while clamping positive transients on the cathode-connected line to ground. Its unidirectional nature makes it suitable for DC power rail and signal line protection where polarity is fixed, unlike bidirectional variants such as P6SMB10CA.
Is the P6SMB10AHM3/I AEC-Q101 qualified?
Yes, the P6SMB10AHM3/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB series datasheet (Document Number 88370, Revision 09-Jan-2024). The "HM3" denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - validated for use in automotive applications including engine control units and ADAS sensor interfaces.
What is the maximum clamping voltage of the P6SMB10AHM3/I under surge conditions?
The P6SMB10AHM3/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current, tested with a 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream components like microcontrollers or transceivers remain within their absolute maximum voltage ratings.
How does the P6SMB10AHM3/I differ from the P6SMB10A-E3/52 variant?
The P6SMB10AHM3/I differs from P6SMB10A-E3/52 in three key aspects: (1) HM3 indicates halogen-free and AEC-Q101 qualification, whereas E3 is commercial-grade only; (2) the "I" suffix denotes 3200-unit tape-and-reel packaging on 13-inch reels, versus "52" for 750-unit 7-inch reels; (3) HM3 meets JESD 201 Class 2 whisker resistance, enhancing long-term reliability in high-vibration environments.
What PCB pad layout is required to achieve the full 600 W rating of the P6SMB10AHM3/I?
To achieve the full 600 W peak pulse power rating, the P6SMB10AHM3/I must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay P6SMB datasheet. Smaller pads increase thermal resistance and reduce surge current handling - for example, reducing pad size to 2.5 mm × 2.5 mm may derate IPPM by ~25%, compromising IEC 61000-4-5 compliance.
