Product details
Overview
P6SMB110AHM3/H 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/H datasheet, P6SMB110AHM3/H pinout, P6SMB110AHM3/H application, or P6SMB110AHM3/H equivalent, this part delivers AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified clamping performance under repetitive surge conditions - critical for automotive-grade power rail and interface line protection.
Technical Context
This unidirectional TVS operates with a reverse stand-off voltage (VWM) of 94.0 V and exhibits ≤1.0 µA maximum reverse leakage at that voltage. Its 152 V clamping voltage ensures safe voltage limiting during 10/1000 µs transients up to 3.9 A, while its 100 °C/W junction-to-ambient thermal resistance requires appropriate PCB copper pad layout (0.2" × 0.2") for sustained power dissipation.
The device features glass-passivated junction construction, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band; no marking on bidirectional variants - confirming P6SMB110AHM3/H's unidirectional identity per its "A" suffix and HM3 automotive qualification code.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines reliable conduction onset under transient overvoltage |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (ISO 7637-2 Pulse 5a, up to 120 V/100 ms). IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp overvoltage before it reaches DC-DC converters or microcontrollers. Use Value: Clamps to 152 V at 3.9 A, limiting stress on 36 V-rated input stages and maintaining system uptime during alternator regulation faults. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS on differential or single-ended signal lines, positioned adjacent to connector entry points. Use Value: Sub-1 µA leakage at 94 V ensures minimal impact on 24-bit ADC accuracy; fast response preserves signal integrity during ±8 kV contact ESD. |
| Telecom Line Surge Suppression | Consumer Power Adapter Input Protection |
Use Scenario: Safeguarding PoE-powered Ethernet PHY interfaces against lightning-induced surges on twisted-pair cables. IC Role / Device Role / Timing Role: Primary-level TVS on DC input side of isolated DC-DC stage, coordinated with secondary-side protection. Use Value: 600 W rating handles IEC 61000-4-5 Combination Wave (10/700 µs) surges up to 4 kV, preventing latch-up in Ethernet controllers. |
Use Scenario: Adding secondary-side overvoltage protection on 5–24 V USB-C PD adapter outputs against regulator fault conditions. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to output ground, triggered only during positive overvoltage events. Use Value: 94 V VWM allows use on 24 V rails with 20 % margin; 152 V VC ensures connected devices remain within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/5B | Same VBR range (105–116 V), but SMA package (smaller footprint, higher RθJA = 140 °C/W), non-automotive grade | Limited to commercial-temp, space-constrained PCBs where thermal derating permits lower surge duty cycle | Select when board area is critical and AEC-Q101 is not required; verify thermal margin with 0.1" × 0.1" pads |
| 1.5SMC110A | Same electrical specs but SMC (DO-214AB) package - larger body (0.275" × 0.165"), higher IPPM (4.2 A), same VC | Better thermal mass for higher average surge repetition rates; requires larger PCB real estate | Choose for industrial power supplies needing enhanced thermal endurance without changing circuit design |
Compared with SMAJ110A-E3/5B and 1.5SMC110A, P6SMB110AHM3/H uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB footprint - making it the optimal choice for automotive modules where reliability, regulatory alignment, and assembly compatibility are jointly mandated.

FAQ
What is the clamping voltage of P6SMB110AHM3/H under standard surge conditions?
The P6SMB110AHM3/H has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 3.9 A. This value is measured per JEDEC standards and confirmed in Vishay's datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream circuits during transient events.
Is P6SMB110AHM3/H suitable for automotive applications?
Yes, P6SMB110AHM3/H is AEC-Q101 qualified (indicated by the HM3 suffix), halogen-free, and RoHS-compliant - meeting requirements for under-hood and chassis-mounted electronic control units. Its 150 °C maximum junction temperature and validated surge performance make it suitable for automotive power rail and sensor line protection per ISO 7637-2.
What does the "HM3" suffix signify in P6SMB110AHM3/H?
The "HM3" suffix in P6SMB110AHM3/H denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. It also specifies packaging in 7" tape-and-reel (H) format and confirms compliance with JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1 handling requirements.
How does P6SMB110AHM3/H differ from bidirectional variants like P6SMB110CA?
P6SMB110AHM3/H is unidirectional (cathode-banded), intended for DC rail protection where polarity is fixed; P6SMB110CA is bidirectional (no band), used for AC or differential signal lines. Their VBR, VC, and PPPM are identical, but P6SMB110AHM3/H cannot suppress negative-going transients without external biasing.
What PCB layout guidance applies to P6SMB110AHM3/H for optimal thermal performance?
Vishay specifies mounting P6SMB110AHM3/H on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Reducing pad size increases thermal resistance and requires derating per Figure 2 in datasheet 88370; insufficient copper may cause premature failure during repetitive surges.
