Product details
Overview
P6SMB110A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 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, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD.
For engineers reviewing the P6SMB110A-E3/52 datasheet, P6SMB110A-E3/52 pinout, P6SMB110A-E3/52 application, or P6SMB110A-E3/52 equivalent, this device delivers verified unidirectional clamping performance in SMB (DO-214AA) package, with RoHS-compliant matte tin plating, MSL Level 1 rating, and AEC-Q101 qualification available via alternate suffixes - critical for automotive, industrial, and telecom surge protection design validation.
Technical Context
The P6SMB110A-E3/52 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable reverse breakdown and fast response (<1 ns). Its clamping action begins at 94.0 V stand-off voltage (VWM) and limits transient energy with low incremental surge resistance and excellent thermal stability up to TJ = 150 °C.
Rated for 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, it sustains repetitive surges when mounted on 5.0 mm × 5.0 mm copper pads per terminal. The device exhibits a +0.107 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across operating temperature range (−65 °C to +150 °C).
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 window for reliable overvoltage triggering |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage during full 600 W transient, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling capability with standardized 10/1000 μs waveform |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient, informs derating requirements on standard PCB layout |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms half-sine), relevant for fault-current scenarios |
| TJ max. | +150 °C - maximum junction temperature, enabling operation in high-ambient industrial environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; polarity-critical for unidirectional operation.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs and body control modules from load-dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive-going surges above 94 V.

Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and wall chargers after rectification. IC Role / Device Role / Timing Role: Unidirectional suppressor on 5–20 V output rail to prevent damage from feedback loop faults or regulator failures. Use Value: 94 V stand-off supports wide-output-range designs; 150 °C TJ max enables compact, thermally constrained layouts. |
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 3.0 A | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select only if board space constraints require SMA package and surge energy is <400 W |
| 1.5SMC110A | Higher PPPM = 1500 W, larger SMC (DO-214AB) package, VC = 170 V at 8.8 A | Better for high-energy industrial mains protection; requires larger PCB footprint and thermal relief | Choose when system-level testing demands >600 W margin or legacy SMC footprint compatibility is required |
Compared with SMAJ110A and 1.5SMC110A, the P6SMB110A-E3/52 offers optimal balance of 600 W surge capacity, SMB footprint efficiency, and 152 V clamping - making it preferred for space-constrained automotive and telecom modules where both performance and manufacturability matter.

FAQ
What is the maximum clamping voltage of the P6SMB110A-E3/52 under surge conditions?
The P6SMB110A-E3/52 has a maximum clamping voltage (VC) of 152 V at 3.9 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during worst-case transients. Designers must ensure downstream components tolerate this clamped level, especially when coordinating with secondary protection stages.
Is the P6SMB110A-E3/52 suitable for automotive applications?
Yes - the base P6SMB110A-E3/52 is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified version is designated as P6SMB110AHE3_B/E3 (with "_B" suffix). While P6SMB110A-E3/52 itself is not AEC-Q101 certified, its construction (glass passivation, MSL Level 1, 150 °C TJ) aligns with automotive environmental requirements, and many Tier 1 suppliers use it in non-safety-critical modules pending qualification validation.
What does the "-E3/52" suffix indicate in P6SMB110A-E3/52?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7-inch diameter plastic tape and reel containing 750 units. This ordering code ensures compatibility with standard SMT pick-and-place equipment and meets IPC/JEDEC moisture sensitivity Level 1 handling requirements without baking prior to reflow.
How does the P6SMB110A-E3/52 compare to bidirectional TVS diodes like P6SMB110CA?
The P6SMB110A-E3/52 is unidirectional and intended for DC line protection with defined polarity; P6SMB110CA is bidirectional and used in AC or floating signal paths. Key differences include cathode band marking (present on P6SMB110A-E3/52, absent on P6SMB110CA) and reverse leakage behavior - the unidirectional part blocks in forward bias, while the bidirectional conducts symmetrically. System topology determines correct selection.
What is the thermal resistance and how does it affect PCB layout for P6SMB110A-E3/52?
The P6SMB110A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W under standard test conditions (0.2" × 0.2" copper pads per terminal). To maintain safe junction temperatures during repetitive surges, designers must provide adequate copper area and consider airflow - reducing RθJA via thermal vias or larger pads directly improves power dissipation margin and long-term reliability of the P6SMB110A-E3/52.
