Product details
Overview
P6SMB110AHM3_B/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 automotive and industrial power electronics.
For engineers reviewing the P6SMB110AHM3_B/H datasheet, P6SMB110AHM3_B/H pinout, P6SMB110AHM3_B/H application, or P6SMB110AHM3_B/H equivalent, this part delivers AEC-Q101 qualified surge protection with halogen-free RoHS compliance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial motor drives.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VWM = 94.0 V, then avalanches to clamp at ≤152 V. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while the SMB package enables automated placement on dense PCBs.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), supporting continuous power dissipation of 5.0 W at TA = 50 °C. The cathode band marking identifies polarity, and the device meets JESD201 Class 2 whisker resistance.
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 steady-state reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage under 600 W 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling capability per standard 10/1000 μs waveform, 0.01% duty cycle |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine), supports inrush current immunity |
| TJ max. | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.130" footprint and matte tin-plated leads |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with cathode band marking; terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side reference; carries full surge current during clamping |
| Cathode | Reverse-biased terminal | Connected to protected line (e.g., 12 V rail or sensor input); avalanche initiates here during overvoltage |
Key Features

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 lower PPPM = 400 W and higher VC = 177 V; SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 Pulse 5a | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with RθJA = 140 °C/W |
| 1.5SMC110A | Same electrical specs (VBR, VC, PPPM), but SMC (DO-214AB) package - 20 % larger footprint, lower RθJA = 75 °C/W | Better thermal performance for sustained surge duty cycles; compatible with legacy SMC layouts | Choose for improved thermal headroom in high-ambient environments (>85 °C) or where existing SMC footprints exist |
Compared with SMAJ110A-E3/5B and 1.5SMC110A, P6SMB110AHM3_B/H offers optimal balance of AEC-Q101 qualification, halogen-free compliance, SMB footprint density, and verified 600 W surge handling - making it the preferred choice for new automotive and industrial designs requiring production-grade reliability.

FAQ
What is the maximum clamping voltage of the P6SMB110AHM3_B/H under a 600 W surge?
The P6SMB110AHM3_B/H has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current of 3.9 A, corresponding to a 600 W 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and represents the upper limit of voltage seen by protected circuitry during worst-case surge conditions. The P6SMB110AHM3_B/H maintains this clamping performance across its operating junction temperature range of –65 °C to +150 °C.
Is P6SMB110AHM3_B/H AEC-Q101 qualified and what does the "HM3_B/H" suffix indicate?
Yes, P6SMB110AHM3_B/H is AEC-Q101 qualified - confirmed by Vishay's ordering information table specifying "_B" suffix for AEC-Q101 qualification on P6SMB6.8A to P6SMB220A variants. The "HM3" denotes halogen-free and RoHS-compliant construction, while "_B/H" indicates AEC-Q101 qualification and 7" tape-and-reel packaging (750 units per reel). This makes the P6SMB110AHM3_B/H suitable for automotive under-hood and chassis applications requiring certified reliability.
How does the SMB (DO-214AA) package of P6SMB110AHM3_B/H compare thermally to larger packages like SMC?
The SMB package of P6SMB110AHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, versus ~75 °C/W for the larger SMC (DO-214AB) package. This means the P6SMB110AHM3_B/H requires careful thermal layout - such as increased copper area or thermal vias - to sustain repeated 600 W surges. Its junction-to-lead resistance (RθJL) is 20 °C/W, enabling effective heat transfer to PCB traces when properly soldered.
Can P6SMB110AHM3_B/H be used in bidirectional configurations?
No, P6SMB110AHM3_B/H is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA") and cathode band marking. Bidirectional operation requires the "CA" variant (e.g., P6SMB110CA), which lacks polarity marking and conducts symmetrically in both directions. Using P6SMB110AHM3_B/H in a bidirectional circuit would result in forward conduction during negative transients, potentially damaging the device or failing to protect downstream components.
What is the reverse leakage current specification for P6SMB110AHM3_B/H at its working voltage?
The P6SMB110AHM3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 94.0 V, measured at TA = 25 °C. This ultra-low leakage ensures minimal power loss and no measurable loading on 94 V nominal circuits during normal operation. Leakage remains below 5 μA up to 85 °C ambient, supporting stable performance in industrial temperature ranges without compromising system efficiency.
