Product details
Overview
P6SMB10AHM3_B/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 (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power supply rails.
For engineers reviewing the P6SMB10AHM3_B/I datasheet, P6SMB10AHM3_B/I pinout, P6SMB10AHM3_B/I application, or P6SMB10AHM3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, unidirectional polarity with cathode band marking, and halogen-free RoHS-compliant construction under HM3 suffix.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance standby to low-impedance conduction when reverse voltage exceeds its 10.5 V breakdown threshold (VBR min), limiting transient energy to safe levels across protected circuit nodes. Its glass-passivated junction ensures stable leakage (<10 μA at VWM) and fast response time (<1 ns).
Designed for automated SMT assembly on standard PCB pads (0.2" × 0.2"), the P6SMB10AHM3_B/I delivers repeatable 600 W surge handling at 0.01% duty cycle and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, supporting high-reliability automotive electronics where junction temperature must stay below 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 8.55 V - Maximum continuous reverse operating voltage before clamping begins; defines maximum DC/AC signal rail voltage it can protect without leakage. |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - Voltage range at which device enters avalanche conduction; ensures predictable turn-on margin above VWM. |
| VC (Clamping) | 14.5 V at 41.4 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM | 600 W - Peak transient power dissipation capability; validates protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω). |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush current immunity in power-up scenarios. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal derating limit for sustained operation in enclosed enclosures. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs PCB thermal design requirements. |

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 PPPM (400 W), higher VC (16.7 V), non-AEC-Q101, RoHS-compliant E3 suffix only. | Lacks automotive qualification and thermal robustness; suitable for commercial-grade consumer power supplies only. | Select when cost sensitivity outweighs automotive reliability requirements and surge threat level is ≤IEC 61000-4-5 Level 3. |
| 1.5SMC10A | Same electrical specs but in larger SMC (DO-214AB) package; 1.5 kW PPPM rating; no AEC-Q101 option; lead-free matte tin plating. | Requires larger PCB footprint and different pad layout; higher power headroom but incompatible with space-constrained automotive modules. | Choose when board area permits and system-level surge testing demands >600 W margin, e.g., heavy-duty industrial motor drives. |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, the P6SMB10AHM3_B/I uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized 600 W/14.5 V clamping in the compact SMB footprint-making it the preferred choice for space-limited, thermally constrained automotive and industrial control units requiring zero-compromise transient immunity.

FAQ
What is the clamping voltage of the P6SMB10AHM3_B/I under maximum rated surge current?
The P6SMB10AHM3_B/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 41.4 A with a 10/1000 μs waveform. This value is measured at 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB10AHM3_B/I maintains this clamping performance across its specified operating temperature range, ensuring consistent protection behavior in automotive under-hood environments.
Is the P6SMB10AHM3_B/I suitable for bidirectional transient suppression?
No, the P6SMB10AHM3_B/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. It conducts only in reverse bias above VBR and blocks forward current beyond its 3.5 V forward voltage at 50 A. For bidirectional protection, Vishay offers the P6SMB10CA variant. Using the P6SMB10AHM3_B/I in bidirectional configurations risks forward conduction failure or inadequate clamping during positive-going transients.
What does the "HM3_B/I" suffix signify in P6SMB10AHM3_B/I?
The "HM3" denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance; "B" indicates AEC-Q101 qualification for the 6.8 V to 220 V voltage range; "I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms the P6SMB10AHM3_B/I meets automotive reliability, environmental, and logistics requirements out of the box.
How does the thermal resistance of the P6SMB10AHM3_B/I affect PCB layout?
The P6SMB10AHM3_B/I has a typical RθJA of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. To maintain junction temperature below 150 °C during repetitive surges, PCB layout must provide adequate copper area and minimize trace length between the P6SMB10AHM3_B/I cathode/anode and respective ground/power planes. Reducing pad size or using thin copper increases thermal resistance and risks thermal runaway during sustained transient activity.
Can the P6SMB10AHM3_B/I replace older P6SMB10A variants in existing designs?
Yes-the P6SMB10AHM3_B/I is a direct functional and mechanical replacement for legacy P6SMB10A parts in the same SMB package, with identical electrical characteristics (VWM = 8.55 V, VC = 14.5 V, PPPM = 600 W). Its added AEC-Q101 qualification, halogen-free materials, and enhanced MSL Level 1 rating make it suitable for drop-in upgrades in automotive and industrial applications where reliability and compliance are critical. No PCB changes are required.
