Product details
Overview
P6SMB110AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and automotive electronics.
For engineers reviewing the P6SMB110AHM3_A/I datasheet, P6SMB110AHM3_A/I pinout, P6SMB110AHM3_A/I application, or P6SMB110AHM3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), polarity marking (cathode band), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction, designed to shunt transient energy away from sensitive downstream circuitry by entering avalanche conduction when reverse voltage exceeds VBR. Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Mounted on 5.0 mm × 5.0 mm copper pads per JEDEC standard, it achieves 600 W peak pulse power dissipation and supports operating junction temperatures from –65 °C to +150 °C. 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 |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA, ensuring no false triggering during normal operation |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage limits protected circuit stress during worst-case 600 W transient events |
| IPPM | 3.9 A - peak pulse current capability under standardized 10/1000 μs waveform, directly tied to PCB pad layout and thermal design |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance determines required board copper area and airflow for sustained power handling |
| TJ max. | +150 °C - maximum junction temperature enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" × 0.130" footprint, optimized for automated placement and reflow compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A | Same VBR range (105–116 V), but lower PPPM = 400 W and higher VC = 177 V at 3.5 A; SMA package (smaller thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select only for cost-sensitive consumer applications where 600 W surge immunity is not required. |
| 1.5SMC110A | Same VBR/VC specs, but SMC package (larger footprint, RθJA = 50 °C/W); higher IPPM = 5.4 A; non-AEC-Q101 | Better thermal performance but incompatible with space-constrained SMB layouts; lacks automotive qualification | Choose when board real estate allows SMC and AEC-Q101 is not mandated; avoid for automotive OEM designs. |
Compared with SMAJ110A and 1.5SMC110A, P6SMB110AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free compliance, SMB footprint, and full 600 W surge capability-making it the only drop-in solution for automotive and industrial designs requiring validated reliability in compact layouts.

FAQ
What is the maximum clamping voltage of P6SMB110AHM3_A/I under a 10/1000 μs transient?
The maximum clamping voltage (VC) of P6SMB110AHM3_A/I is 152 V at 3.9 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads and represents the upper limit of voltage seen by protected circuitry during worst-case surge events. P6SMB110AHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is P6SMB110AHM3_A/I qualified for automotive applications?
Yes, P6SMB110AHM3_A/I is AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code. This qualification validates its reliability for automotive applications including engine control, body electronics, and ADAS sensor interfaces. The device meets stress test requirements for temperature cycling, humidity bias, and mechanical shock, and is halogen-free and RoHS-compliant per JESD201 Class 2.
What does the "A/I" suffix mean in P6SMB110AHM3_A/I?
The "A/I" suffix in P6SMB110AHM3_A/I indicates packaging configuration: "A" denotes the standard SMB tape-and-reel orientation (anode first), and "I" specifies 13-inch diameter reels with 3200 units per reel. This format supports high-volume automated assembly and is consistent with Vishay's ordering nomenclature for AEC-Q101 qualified HM3 variants in the P6SMB series.
How does P6SMB110AHM3_A/I differ from the non-HM3 version?
P6SMB110AHM3_A/I differs from non-HM3 versions (e.g., P6SMB110A-E3) by incorporating halogen-free molding compound, RoHS compliance, and formal AEC-Q101 qualification. While electrical parameters like VBR, VC, and PPPM remain identical, the HM3 variant adds automotive-grade reliability validation, JESD201 Class 2 whisker resistance, and stricter process controls-making P6SMB110AHM3_A/I mandatory for Tier 1 automotive designs.
What is the thermal resistance of P6SMB110AHM3_A/I, and how does it affect layout?
P6SMB110AHM3_A/I 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. This value dictates minimum copper area requirements: reducing pad size increases RθJA, risking thermal runaway during repetitive surges. For continuous 5.0 W power dissipation, ambient temperature must stay below 100 °C to keep TJ ≤ 150 °C. P6SMB110AHM3_A/I's RθJA is optimized for standard FR-4 PCBs without thermal vias.
