Product details
Overview
P6SMB10AHM3_A/I 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), 14.5 V clamping voltage (VC) at 41.4 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform. 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/I datasheet, P6SMB10AHM3_A/I pinout, P6SMB10AHM3_A/I application, or P6SMB10AHM3_A/I equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial motor drives.
Technical Context
This unidirectional TVS operates by avalanche breakdown above its 9.5–10.5 V breakdown voltage (VBR at 1 mA), delivering precise overvoltage clamping with 0.073 %/°C temperature coefficient. Its glass-passivated junction ensures stable leakage (<10 μA at 8.55 V) and fast response time under transient stress.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and maintains operation across –65 °C to +150 °C junction temperature range, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 9.5–10.5 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping) | 14.5 V at 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream components. |
| PPPM | 600 W - Sustained peak pulse power handling per JEDEC standard; enables robust protection against IEC 61000-4-5 surges. |
| IPPM | 41.4 A - Maximum non-repetitive peak pulse current; determines minimum trace width and PCB pad design for surge path. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
| RθJA | 100 °C/W - Thermal resistance to ambient; informs heatsinking requirements when operating near PD = 5.0 W derated limit. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, MSL Level 1 (260 °C reflow peak), UL 94 V-0 molding compound. Cathode indicated by band on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to ground or low-side return path; defines polarity-sensitive placement in unidirectional protection circuits. |
| Cathode | Avalanche conduction terminal / Clamping node | Connected to protected line (e.g., VIN, signal rail); conducts surge current to ground when VIN exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control, ADAS, and body electronics. |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 Level 4 surge immunity without external series impedance - simplifies front-end protection design. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients - preserves margin for 12 V logic interfaces and 3.3 V microcontrollers. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Complies with EU Directive 2011/65/EU and JESD201 Class 2 whisker resistance - suitable for export-controlled and green manufacturing programs. |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without dry-bag storage or baking - reduces production line complexity and cost. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp positive-going surges.

IC Role / Device Role / Timing Role: Unidirectional TVS from gate to source to prevent VGS overstress during fast dV/dt switching. Use Value: 14.5 V clamping ensures gate oxide remains within safe 20 V absolute maximum rating during 100 ns edge transitions. |
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 lower 400 W PPPM; no AEC-Q101 qualification; commercial-grade only. | Lacks automotive qualification and halogen-free compliance; suitable for consumer-grade power supplies only. | Select when cost sensitivity outweighs automotive reliability requirements and surge energy is limited to ≤400 W. |
| 1.5SMC10A | Higher-power SMC package (same VWM/VC specs), 1500 W PPPM, larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm), not AEC-Q101 qualified. | Requires PCB redesign due to larger case; used where higher surge margin is needed but automotive qualification is not mandated. | Choose when system-level surge testing exceeds 600 W and board space allows SMC footprint. |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, P6SMB10AHM3_A/I uniquely delivers AEC-Q101 qualification, halogen-free construction, and 600 W capability in the compact SMB outline - making it the only drop-in option for space-constrained, automotive-grade designs requiring full compliance traceability.

FAQ
What is the clamping voltage of P6SMB10AHM3_A/I at its rated peak pulse current?
The P6SMB10AHM3_A/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A using the standard 10/1000 μs waveform. This value is measured under defined test conditions per JEDEC standards and ensures predictable overvoltage limiting for protected circuits. The P6SMB10AHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is P6SMB10AHM3_A/I qualified for automotive applications?
Yes, P6SMB10AHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB datasheet (Document Number 88370, Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and surge endurance - validating its suitability for under-hood and body-control module applications. The P6SMB10AHM3_A/I meets all requirements for automotive-grade transient suppression.
What does the "HM3" suffix indicate in P6SMB10AHM3_A/I?
The "HM3" suffix in P6SMB10AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 qualification, "M" signifies halogen-free molding compound, and "3" confirms RoHS compliance per EU Directive 2011/65/EU. The trailing "_A/I" specifies tape-and-reel packaging (3200 units per 13-inch reel). This makes P6SMB10AHM3_A/I compliant with both environmental and automotive reliability mandates.
How does P6SMB10AHM3_A/I differ from bidirectional variants like P6SMB10CA?
P6SMB10AHM3_A/I is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where surge polarity is known (e.g., positive supply lines). In contrast, P6SMB10CA is bidirectional, symmetric in both directions, and used for AC lines or differential signals. The P6SMB10AHM3_A/I exhibits forward conduction characteristics and higher IFSM (100 A), while P6SMB10CA lacks forward surge rating and shows identical VBR in both directions.
What is the maximum operating junction temperature for P6SMB10AHM3_A/I?
The maximum operating junction temperature (TJ) for P6SMB10AHM3_A/I is +150 °C, as specified in the Vishay P6SMB datasheet. This rating enables reliable operation in high-ambient environments such as engine compartments or sealed industrial enclosures. Derating curves in Figure 2 of the datasheet define allowable power dissipation above 25 °C ambient, ensuring thermal safety margins are maintained throughout the P6SMB10AHM3_A/I's operational life.
