Product details
Overview
P6SMB110AHM3/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 in industrial motor drives.
For engineers reviewing the P6SMB110AHM3/I datasheet, P6SMB110AHM3/I pinout, P6SMB110AHM3/I application, or P6SMB110AHM3/I equivalent, key selection criteria include unidirectional polarity, 94.0 V stand-off voltage (VWM), <1.0 μA reverse leakage at VWM, AEC-Q101 qualification (HM3 suffix), and halogen-free RoHS compliance - all critical for automotive-grade ESD/surge protection in harsh environments.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1.0 μA leakage at 94.0 V), then rapidly avalanches below 152 V to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
The device uses a single-junction avalanche structure with defined thermal resistance (RθJA = 100 °C/W, RθJL = 20 °C/W) and is rated for continuous operation from –65 °C to +150 °C junction temperature. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification per revision "I" tape-and-reel packaging.
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 operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage during 600 W transient, limiting stress on protected ICs |
| IPPM | 3.9 A (10/1000 μs waveform) - peak surge current capability determines robustness against common lightning/inductive spikes |
| PPPM | 600 W - standardized surge power rating enabling direct comparison across TVS families |

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 non-AEC-Q101; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to commercial-grade consumer/industrial use; not suitable for automotive under-hood deployment | Select SMAJ110A only if space-constrained layout permits smaller SMA and AEC-Q101 is not required. |
| 1.5SMC110A | Higher PPPM = 1500 W, same VBR/VC, but larger SMC (DO-214AB) package and no AEC-Q101 qualification in standard version | Better suited for high-energy surge zones (e.g., AC input stages), but incompatible with automated placement for SMB footprints | Choose 1.5SMC110A when surge energy exceeds 600 W and board space allows SMC mounting. |
Compared with SMAJ110A and 1.5SMC110A, P6SMB110AHM3/I uniquely balances AEC-Q101 qualification, halogen-free compliance, SMB footprint compatibility, and 600 W surge rating - making it the optimal choice for automotive and industrial applications where reliability, regulatory alignment, and assembly scalability are jointly prioritized.

FAQ
What is the exact breakdown voltage range for P6SMB110AHM3/I?
The P6SMB110AHM3/I has a guaranteed breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, as specified in the Vishay datasheet revision 09-Jan-2024. This tight ±5 % tolerance ensures predictable clamping behavior in precision protection circuits, and the value is measured under controlled 25 °C conditions with defined pulse parameters. The P6SMB110AHM3/I maintains this specification across its qualified operating temperature range.
Is P6SMB110AHM3/I suitable for automotive applications?
Yes, P6SMB110AHM3/I is AEC-Q101 qualified (confirmed by the "HM3" suffix and revision "I" packaging code), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free, RoHS-compliant construction, MSL Level 1 rating, and operational junction temperature range of –65 °C to +150 °C meet stringent automotive reliability requirements. The P6SMB110AHM3/I is explicitly validated for thermal cycling, mechanical shock, and humidity exposure per AEC-Q101 test conditions.
What does the "HM3/I" suffix indicate in P6SMB110AHM3/I?
The "HM3" suffix in P6SMB110AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification; the trailing "I" specifies the tape-and-reel packaging revision code per Vishay's ordering nomenclature. This distinguishes it from commercial-grade "E3" or "M3" variants and confirms compliance with automotive environmental and reliability standards. The P6SMB110AHM3/I is supplied in 13-inch reels (3200 units) with moisture sensitivity level 1 and peak reflow temperature support up to 260 °C.
How does P6SMB110AHM3/I compare to bidirectional TVS diodes like P6SMB110CA?
P6SMB110AHM3/I is unidirectional and features a cathode band marking, intended for DC-coupled protection where polarity is fixed (e.g., 12 V supply rail to ground). In contrast, P6SMB110CA is bidirectional with no polarity marking and symmetric clamping in both directions - used in AC or floating signal lines. The P6SMB110AHM3/I offers lower leakage (<1.0 μA at 94.0 V) than its bidirectional counterpart and is optimized for automotive-grade DC protection, whereas P6SMB110CA targets telecom or data line applications requiring dual-polarity suppression.
What is the maximum clamping voltage of P6SMB110AHM3/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB110AHM3/I is 152 V at 3.9 A peak pulse current (IPPM) using the standardized 10/1000 μs waveform. This value represents the upper limit of voltage seen by protected circuitry during a 600 W transient event and is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC guidelines. The P6SMB110AHM3/I maintains this clamping performance across its full operating temperature range without derating up to +125 °C junction temperature.
