Product details
Overview
P6SMB110AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 110 V standoff voltage (VWM), 152 V clamping voltage at 3.9 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB110AHE3/5B datasheet, P6SMB110AHE3/5B pinout, P6SMB110AHE3/5B application, or P6SMB110AHE3/5B equivalent, this AEC-Q101 qualified, RoHS-compliant TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The P6SMB110AHE3/5B operates as a unidirectional avalanche breakdown device with a nominal breakdown voltage (VBR) of 105–116 V at 1 mA test current, enabling precise overvoltage thresholding. Its glass-passivated junction ensures stable leakage (<1 μA at 94 V) and fast response time (<1 ns) to transient events.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = 150 °C. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD22-B102 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 94.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown) | 105–116 V at 1 mA - precise avalanche initiation range for predictable overvoltage triggering |
| VC (Clamping) | 152 V at IPPM = 3.9 A - limits downstream voltage stress during 10/1000 μs transients |
| PPPM | 600 W - peak surge energy absorption capability under standardized IEC 61000-4-5 waveform |
| ID (Leakage) | <1.0 μA at 94 V - minimal DC loading on protected circuitry during normal operation |
| TJ max. | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Package | SMB (DO-214AA) - compact 0.220" × 0.130" footprint compatible with automated SMT placement |

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 VWM (94 V), VC = 177 V at 3.5 A; lower PPPM (400 W); SMA package (smaller, higher RθJA) | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W margin is required | Select P6SMB110AHE3/5B when 600 W rating, AEC-Q101, or SMB mechanical robustness are mandatory |
| 1.5SMC110A | Same VWM/VC specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W; no AEC-Q101 option | Better thermal dissipation but incompatible with dense layouts requiring SMB footprint | Choose P6SMB110AHE3/5B for space-constrained AEC-Q101 designs where SMB mounting and MSL Level 1 are essential |
Compared with SMAJ110A-E3/5B and 1.5SMC110A, the P6SMB110AHE3/5B uniquely delivers AEC-Q101 qualification, 600 W surge capacity in the compact SMB outline, and MSL Level 1 compatibility - making it the optimal choice for automotive and high-density industrial PCBs requiring certified reliability and proven clamping consistency.

FAQ
What is the clamping voltage of the P6SMB110AHE3/5B at its rated peak pulse current?
The P6SMB110AHE3/5B has a maximum clamping voltage (VC) of 152 V at its specified peak pulse current (IPPM) of 3.9 A, measured under the standard 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and reflects worst-case performance across temperature and production lot variation - critical for validating voltage margins in protected circuits. The P6SMB110AHE3/5B maintains this clamping level while dissipating 600 W of transient energy.
Is the P6SMB110AHE3/5B suitable for automotive applications?
Yes, the P6SMB110AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix (RoHS-compliant + AEC-Q101) and "_B" revision code. It passes stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD47, and is rated for operation from –65 °C to +150 °C. The P6SMB110AHE3/5B is commonly deployed in engine control units, body electronics, and ADAS sensor interfaces where certified surge immunity is required.
What does the "/5B" in P6SMB110AHE3/5B indicate?
The "/5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel, with a standard quantity of 3200 pieces per reel. This format supports high-volume SMT assembly and is compatible with industry-standard pick-and-place equipment. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "B" indicates the revision level per Vishay's internal documentation. The P6SMB110AHE3/5B thus combines automotive-grade reliability with optimized logistics for production-scale deployment.
How does the P6SMB110AHE3/5B compare to bidirectional TVS diodes like P6SMB110CA?
The P6SMB110AHE3/5B is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB110CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6SMB110AHE3/5B offers tighter leakage control (<1 μA at 94 V) and is preferred for DC-coupled lines like power rails or single-ended signal paths. In contrast, P6SMB110CA suits AC-coupled or differential interfaces such as RS-485. Both share identical VWM, VC, and PPPM ratings, but only the P6SMB110AHE3/5B carries AEC-Q101 certification in this variant.
What is the thermal resistance of the P6SMB110AHE3/5B, and how does it affect layout?
The P6SMB110AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per Vishay's standard test board. To maintain safe operation under repetitive surges, PCB layout must provide adequate copper area - minimum 5.0 mm × 5.0 mm per terminal - and avoid thermal bottlenecks. The P6SMB110AHE3/5B's RθJL value confirms efficient heat transfer to the PCB, making it suitable for thermally constrained automotive modules where ambient temperatures exceed 105 °C.
