Product details
Overview
P6SMB110AHM3_A/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_A/H datasheet, P6SMB110AHM3_A/H pinout, P6SMB110AHM3_A/H application, or P6SMB110AHM3_A/H equivalent, this part delivers AEC-Q101 qualification, 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 protection design.
Technical Context
The P6SMB110AHM3_A/H operates as a unidirectional avalanche diode with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ = –65 to +150 °C) support reliable operation on standard 0.2" × 0.2" copper pads without forced cooling.
It meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when applied per recommended PCB layout, with fast response time (<1 ns) and low leakage (≤1.0 µA at VWM = 94.0 V). The device is not bidirectional - no internal symmetry or dual-junction structure - and requires correct cathode orientation in series with protected lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche initiation threshold for overvoltage triggering |

| VC @ IPPM | 152 V at 3.9 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 600 W - peak transient power handling capability under standardized surge waveform |
| IFSM | 100 A - single half-sine surge rating (8.3 ms), supporting inrush and fault-current events |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with automated placement and reflow soldering |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, clamping spikes above 94 V. Use Value: Limits peak voltage to ≤152 V during 3.9 A surges, preventing damage to LDOs and microcontrollers. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) from ESD and field-induced noise in factory automation. IC Role / Device Role / Timing Role: TVS diode installed across signal and return paths near connector entry point. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC inputs saturate or latch up. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras) against lightning-induced surges on 48 V DC input rails. IC Role / Device Role / Timing Role: Primary TVS stage upstream of DC-DC converter, absorbing bulk energy before secondary protection. Use Value: 600 W rating handles multi-pulse surge events without degradation, validated per IEC 61000-4-5 Ed.3. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in home appliances (e.g., washing machine control boards). IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge outputs to clamp inductive kickback. Use Value: 100 A IFSM withstands repeated commutation surges; glass passivation prevents parameter drift over 10,000 cycles. |
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-AEC-Q101 | Limited to commercial-grade applications; unsuitable for under-hood automotive due to lower thermal robustness | Select when board space is constrained and automotive qualification is not required |
| 1.5SMC110AHE3_A | Same electrical specs, but SMC (DO-214AB) package - larger footprint, lower RθJA = 75 °C/W, AEC-Q101 qualified | Better thermal performance for high-duty-cycle surge environments; requires more PCB area | Choose when sustained surge repetition or elevated ambient temperatures demand improved heat dissipation |
Compared with SMAJ110A-E3/5B and 1.5SMC110AHE3_A, the P6SMB110AHM3_A/H uniquely balances AEC-Q101 compliance, SMB footprint compactness, and 100 °C/W thermal resistance - making it optimal for space-constrained automotive modules where both qualification and thermal margin matter.

FAQ
What is the maximum clamping voltage of the P6SMB110AHM3_A/H under a 10/1000 µs surge?
The P6SMB110AHM3_A/H has a maximum clamping voltage (VC) of 152 V at 3.9 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88370 and defines the upper voltage limit imposed on protected circuits during transient events. Designers must ensure downstream components tolerate ≤152 V to maintain functional safety margins. The P6SMB110AHM3_A/H achieves this with low incremental surge resistance and stable avalanche behavior.
Is the P6SMB110AHM3_A/H suitable for automotive applications?
Yes, the P6SMB110AHM3_A/H is AEC-Q101 qualified and designated with the HM3 suffix, indicating halogen-free, RoHS-compliant construction and automotive-grade reliability testing. It supports operation from –65 °C to +150 °C and is validated for use in engine control units, body electronics, and ADAS sensor interfaces. The P6SMB110AHM3_A/H meets MSL Level 1 and passes whisker testing per JESD 201 Class 2, confirming suitability for automotive manufacturing and under-hood deployment.
What does the "HM3" suffix indicate in P6SMB110AHM3_A/H?
The "HM3" suffix in P6SMB110AHM3_A/H specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinct from commercial-grade "M3" or "E3" variants. The "H" denotes tape-and-reel packaging (750 units per 7" reel), while "_A/H" indicates revision level A and packaging format H. This suffix confirms compliance with automotive material standards and guarantees tested reliability for mission-critical transient suppression. The P6SMB110AHM3_A/H is not interchangeable with non-HM3 variants without requalification.
How does the P6SMB110AHM3_A/H differ from bidirectional TVS diodes like P6SMB110CA?
The P6SMB110AHM3_A/H is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB110CA is bidirectional with symmetric breakdown in both directions and no polarity marking. Unidirectional operation allows lower leakage (<1.0 µA at 94.0 V) and tighter VBR tolerance, making the P6SMB110AHM3_A/H ideal for DC power rail protection. Bidirectional types suit AC or floating signal lines but exhibit higher leakage and reduced precision in DC-clamping applications. The P6SMB110AHM3_A/H cannot replace P6SMB110CA without circuit redesign.
What is the thermal resistance and recommended pad layout for the P6SMB110AHM3_A/H?
The P6SMB110AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Pad dimensions should follow Vishay's SMB outline: 0.086" (2.18 mm) min. width, 0.220" (5.59 mm) reference length. Exceeding these pads reduces RθJA, improving surge endurance. The P6SMB110AHM3_A/H must not be operated above its 150 °C TJ limit - derating curves in Figure 2 apply for ambient temperatures >25 °C.
