Overview
P6SMB10AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 8.55 V stand-off voltage. 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/H datasheet, P6SMB10AHM3/H pinout, P6SMB10AHM3/H application, or P6SMB10AHM3/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 to +150 °C), and halogen-free RoHS compliance per ordering code HM3.
Technical Context
The P6SMB10AHM3/H uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity features a cathode band marking and operates with 10 mA test current for breakdown verification.
Designed for automated SMT placement on 0.2" × 0.2" copper pads, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C) and JESD201 Class 2 whisker resistance. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains transient surges without failure under standard lightning/inductive load test waveform |
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse voltage before leakage exceeds 10 μA; sets operating margin below clamping |
| Breakdown Voltage (VBR) | 9.50–10.5 V at 1.0 mA - sharp avalanche onset ensures predictable turn-on during overvoltage events |
| Clamping Voltage (VC) | 14.5 V at 41.4 A - limits downstream voltage stress to safe levels for 3.3 V/5 V logic and power MOSFETs |
| Junction Temperature Range | –65 to +150 °C - supports operation in under-hood automotive and industrial environments without derating |
| Thermal Resistance (RθJA) | 100 °C/W - defines temperature rise per watt dissipated on standard PCB pad layout (0.2" × 0.2") |
| AEC-Q101 Qualified | Yes - certified for automotive electronics per stress test requirements including HTRB, HTGB, and temperature cycling |

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, 600 W rating, but VWM = 8.55 V, VC = 14.5 V - identical clamping performance; not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial only where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive compliance; verify board-level ESD immunity separately |
| 1.5SMC10A | Higher package thermal resistance (RθJA ≈ 125 °C/W), same VWM/VC, but DO-214AB (SMC) footprint - larger area, incompatible pad layout | Requires PCB redesign due to 7.11 mm × 6.22 mm body vs. SMB's 4.57 mm × 3.94 mm; higher surge margin at cost of space | Choose only if existing design uses SMC footprint or requires >600 W margin; not drop-in compatible |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, the P6SMB10AHM3/H uniquely combines AEC-Q101 qualification, SMB footprint compatibility, and validated 100-cycle surge endurance - making it the preferred choice for space-constrained automotive modules requiring zero-field failure.

FAQ
What is the maximum clamping voltage of the P6SMB10AHM3/H at its rated peak pulse current?
The P6SMB10AHM3/H has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and ensures downstream 5 V logic components remain within safe operating limits during surge events. The P6SMB10AHM3/H maintains this clamping performance across its full operating temperature range.
Is the P6SMB10AHM3/H qualified for automotive applications?
Yes, the P6SMB10AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - confirming suitability for under-hood and body electronics. The P6SMB10AHM3/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the P6SMB family.
What does the "H" in P6SMB10AHM3/H signify in the ordering code?
The "H" in P6SMB10AHM3/H specifies the packaging format: 7-inch diameter plastic tape and reel, with 750 units per reel. This differs from the "I" suffix (13-inch reel, 3200 units) and aligns with standard SMT assembly line feed requirements. The P6SMB10AHM3/H uses the same die, qualification, and electrical specs as other HM3 variants - only the reel configuration changes with the "H" or "I" designation.
How does the thermal resistance of the P6SMB10AHM3/H affect PCB layout?
The P6SMB10AHM3/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. To maintain junction temperature below 150 °C during repetitive surges, designers must allocate adequate copper area and avoid narrow traces. The P6SMB10AHM3/H thermal performance degrades significantly if pad size falls below minimum recommendations in the Vishay package outline drawing.
Can the P6SMB10AHM3/H replace a bidirectional TVS in a circuit?
No, the P6SMB10AHM3/H is unidirectional and cannot replace a bidirectional TVS without circuit modification. Its cathode band marks the protected line connection, and it conducts only for positive transients relative to ground. Using it in place of a bidirectional part (e.g., P6SMB10CA) would leave negative-going transients unprotected. The P6SMB10AHM3/H must be oriented correctly in the schematic and layout to ensure proper clamping polarity.
