Product details
Overview
P6SMB110AHE3/52 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, and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB110AHE3/52 datasheet, P6SMB110AHE3/52 pinout, P6SMB110AHE3/52 application, or P6SMB110AHE3/52 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 automotive ECUs and industrial control modules requiring robust ESD and surge immunity.
Technical Context
This unidirectional TVS operates with a 94.0 V stand-off voltage (VWM) and exhibits ≤1.0 μA reverse leakage at VWM, enabling reliable high-impedance protection during normal operation. Its 152 V clamping voltage at 3.9 A IPPM ensures downstream circuitry remains below safe voltage thresholds under standardized 10/1000 μs surge events.
The device features glass passivated junction construction, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and thermal resistance of RθJA = 100 °C/W. It is rated for TJ = –65 to +150 °C and meets UL 94 V-0 flammability requirements in its SMB molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise voltage threshold where avalanche conduction begins |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage |
| VC @ IPPM | 152 V at 3.9 A - clamped voltage seen by protected circuit during full 600 W surge event |
| PPPM | 600 W (10/1000 μs waveform) - peak transient energy absorption capability per pulse |
| IPPM | 3.9 A - peak surge current corresponding to VC = 152 V under standard waveform |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" x 0.130" footprint and MSL Level 1 rating |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded unidirectional configuration. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); mounting pad layout requires 5.0 mm × 5.0 mm copper pads per terminal per datasheet Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; grounded reference in unidirectional TVS protection | Connected to system ground or low-impedance return path; enables low-VF clamping during positive transients |
| Cathode | Protected line connection; marked with band on package | Connected to vulnerable signal/power line (e.g., 12 V rail or sensor output); conducts avalanche current to ground when VAK exceeds VBR |
Key Features
| Feature | Design Value |

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-E3/52 | Same VBR range (105–116 V), but lower PPPM = 400 W and higher VC = 177 V at 2.6 A; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W margin is required | Select P6SMB110AHE3/52 when 600 W surge rating and AEC-Q101 qualification are mandatory |
| 1.5SMC110A | Same VBR and PPPM, but SMC (DO-214AB) package - larger footprint (7.11 mm × 6.22 mm), higher thermal mass, RθJA = 60 °C/W | Better thermal performance in high-duty-cycle environments; not space-constrained designs | Choose P6SMB110AHE3/52 for dense PCB layouts needing SMB's compact 4.57 mm × 3.94 mm footprint and automotive qualification |
Compared with SMAJ110A-E3/52 and 1.5SMC110A, P6SMB110AHE3/52 uniquely balances 600 W surge capability, AEC-Q101 compliance, and SMB package size - making it optimal for space-limited automotive and industrial modules where both reliability and board area matter.

FAQ
What is the maximum clamping voltage of P6SMB110AHE3/52 under a 10/1000 μs surge?
The P6SMB110AHE3/52 has a maximum clamping voltage (VC) of 152 V when subjected to its rated peak pulse current of 3.9 A, defined by the 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and ensures protected circuits remain within safe voltage limits during standardized surge events. The P6SMB110AHE3/52 maintains this clamping performance across its specified operating temperature range.
Is P6SMB110AHE3/52 qualified for automotive applications?
Yes, P6SMB110AHE3/52 is AEC-Q101 qualified, as indicated by the "HE3" suffix per Vishay's ordering nomenclature. It undergoes rigorous stress testing including temperature cycling, humidity bias, and surge endurance to meet automotive reliability standards. This qualification makes P6SMB110AHE3/52 suitable for under-hood and cabin ECU applications where long-term stability under thermal and electrical stress is required.
What does the "HE3" suffix signify in P6SMB110AHE3/52?
The "HE3" suffix in P6SMB110AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability requirements. It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive reliability and environmental standards. The "/52" indicates 7" diameter plastic tape-and-reel packaging with 750 units per reel.
How does P6SMB110AHE3/52 compare to bidirectional TVS diodes like P6SMB110CA?
P6SMB110AHE3/52 is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply rails), offering lower leakage and tighter VBR tolerance. In contrast, P6SMB110CA is bidirectional and suited for AC or floating signal lines. The P6SMB110AHE3/52 cannot replace P6SMB110CA in AC-coupled applications due to its inherent polarity - using it incorrectly would result in forward conduction during normal operation.
What is the thermal resistance of P6SMB110AHE3/52, and how does it affect PCB layout?
P6SMB110AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks. Reducing pad size or omitting thermal vias increases RθJA, potentially exceeding the +150 °C TJ limit during sustained operation - a key design consideration for P6SMB110AHE3/52 implementation.
