Product details
Overview
P6SMB110AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 94.0 V maximum stand-off voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB110AHE3_A/I datasheet, P6SMB110AHE3_A/I pinout, P6SMB110AHE3_A/I application, or P6SMB110AHE3_A/I equivalent, this AEC-Q101 qualified TVS offers verified transient suppression performance, RoHS-compliant matte tin-plated leads, MSL Level 1 moisture sensitivity, and validated thermal resistance (RθJA = 100 °C/W) for high-reliability embedded systems requiring robust ESD and surge immunity.
Technical Context
This unidirectional TVS operates by avalanche breakdown to clamp transient overvoltages above its VWM threshold while maintaining low leakage (<1.0 μA at 94.0 V). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), enabling protection of sensitive downstream circuitry during inductive switching events or lightning-induced surges.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports continuous power dissipation of 5.0 W at TA = 50 °C, and maintains operation across -65 °C to +150 °C junction temperature range - making it suitable for under-hood automotive modules and industrial motor drive control boards where thermal cycling and long-term reliability are critical.
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 range for predictable clamping behavior |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 3.9 A - clamped voltage during 600 W 10/1000 μs surge, limiting stress on protected ICs |
| PPPM | 600 W - peak pulse power handling capability per standard 10/1000 μs waveform, duty cycle ≤ 0.01 % |
| IFSM | 100 A - single half-sine surge rating (8.3 ms), supporting protection against inductive kickback in relay/motor circuits |
| TJ max. | +150 °C - enables use in high-temperature environments such as engine control units and power converters |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, informs PCB copper pad sizing for thermal management |

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-E3/5B | Same VWM (94 V), identical SMB package, but lower PPPM = 400 W and higher VC = 177 V at 2.6 A | Limited to lower-energy transients; not recommended for ISO 7637-2 Pulse 5a (load dump) | Select P6SMB110AHE3_A/I when 600 W clamping headroom and automotive-grade qualification are required. |
| 1.5SMC110A | Higher package thermal resistance (RθJA ≈ 125 °C/W), same VBR/VC, but SMC (DO-214AB) footprint - 2.5 mm wider | Requires PCB layout change; less suitable for space-constrained automotive modules | Choose P6SMB110AHE3_A/I for drop-in replacement in SMB-limited layouts and tighter thermal designs. |
Compared with SMAJ110A-E3/5B and 1.5SMC110A, P6SMB110AHE3_A/I delivers superior surge energy handling in the same compact SMB footprint, with AEC-Q101 validation and lower thermal resistance - critical for automotive and industrial applications demanding long-term field reliability under thermal stress.

FAQ
What is the clamping voltage of P6SMB110AHE3_A/I at its rated peak pulse current?
The P6SMB110AHE3_A/I has a maximum clamping voltage (VC) of 152 V at 3.9 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components experience no more than 152 V during a 600 W transient event - a key parameter for validating protection margins in 12 V and 48 V systems.
Is P6SMB110AHE3_A/I qualified for automotive applications?
Yes, P6SMB110AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, making P6SMB110AHE3_A/I suitable for under-hood and chassis-mounted automotive modules where reliability under thermal and mechanical stress is essential.
What is the maximum operating temperature for P6SMB110AHE3_A/I?
The P6SMB110AHE3_A/I has a maximum junction temperature (TJ) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. This wide range supports deployment in engine control units, industrial inverters, and outdoor telecom equipment exposed to extreme ambient conditions - provided PCB thermal design meets the RθJA = 100 °C/W specification.
Does P6SMB110AHE3_A/I have moisture sensitivity level (MSL) rating?
Yes, P6SMB110AHE3_A/I meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This means the device has unlimited floor life and can be placed directly into reflow ovens without pre-baking - simplifying manufacturing for high-volume automotive and industrial assembly lines.
How does the unidirectional configuration of P6SMB110AHE3_A/I affect its circuit placement?
The unidirectional configuration of P6SMB110AHE3_A/I requires correct polarity orientation: the cathode band must connect to the protected line (e.g., 12 V rail), and the anode to ground. This arrangement allows forward conduction only during negative transients on the line, providing precise clamping above VWM while blocking reverse leakage - unlike bidirectional variants which suppress both polarities without polarity dependency.
