Product details
Overview
P6SMB110AHE3_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 automotive and industrial power electronics.
For engineers reviewing the P6SMB110AHE3_A/H datasheet, P6SMB110AHE3_A/H pinout, P6SMB110AHE3_A/H application, or P6SMB110AHE3_A/H equivalent, this device delivers AEC-Q101 qualification, low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial motor drives requiring robust overvoltage immunity without layout redesign.
Technical Context
This unidirectional TVS operates with a reverse stand-off voltage (VWM) of 94.0 V and exhibits ≤1.0 μA maximum reverse leakage at VWM. Its clamping performance is specified at 152 V under 3.9 A IPPM, ensuring predictable voltage limiting during transient events.
The device features glass-passivated junction construction, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and thermal resistance RθJA = 100 °C/W. It is qualified to AEC-Q101 and meets UL 94 V-0 flammability rating 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 or conduction |
| VC @ IPPM | 152 V at 3.9 A - clamped voltage seen by protected circuit during 10/1000 μs transient, limiting stress on downstream components |
| PPPM | 600 W - peak transient power handling capability under standardized 10/1000 μs waveform, enabling protection against severe surges |
| IPPM | 3.9 A - maximum non-repetitive peak pulse current the device safely clamps without degradation |
| TJ max. | +150 °C - maximum junction temperature, supporting operation in under-hood automotive environments and enclosed industrial enclosures |
| Package | SMB (DO-214AA) - surface-mount footprint with 0.220" × 0.205" body, optimized for automated placement and thermal dissipation on 5.0 mm × 5.0 mm copper pads |

Applications
| Automotive Power Distribution Module | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: Protects 12 V/24 V supply rails and load-switch control lines in fuse boxes and junction modules exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp transients before they reach PMICs or microcontrollers. Use Value: Withstands 600 W surges and maintains VC ≤ 152 V, preventing latch-up or burnout in 100 V-rated power switches used in smart fusing circuits. |
Use Scenario: Shields digital input channels of programmable logic controllers from field-wiring induced surges in factory automation systems. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC inputs, positioned ahead of optocouplers and level-shifting buffers. Use Value: Low leakage (<1 μA at 94 V) avoids false triggering; fast response ensures clamping within nanoseconds of surge onset, preserving signal integrity. |
| Motor Drive Gate Driver Protection | Automotive Sensor Signal Line Protection |
|
Use Scenario: Safeguards high-side/low-side gate driver ICs in BLDC inverter stages against Miller-induced spikes and shoot-through transients. IC Role / Device Role / Timing Role: Localized TVS across gate-source terminals or supply pins of isolated gate drivers (e.g., SiC MOSFET drivers). Use Value: 152 V clamping limits gate oxide stress below 20 V margin for 175 V-rated drivers, extending lifetime under repetitive switching stress. |
Use Scenario: Installed on LIN/CAN physical layer signal lines (e.g., ambient temperature, pressure sensors) in engine control units. IC Role / Device Role / Timing Role: Unidirectional suppression element referenced to vehicle ground, filtering ESD and coupled noise without distorting low-speed analog/digital signals. Use Value: AEC-Q101 qualification and 150 °C TJ max ensure compliance with automotive ambient requirements; SMB footprint fits tight sensor module PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/52 | Same VBR range (105–116 V), but lower PPPM = 400 W and higher VC = 177 V at 2.6 A | Limited to less severe surge environments (e.g., consumer-grade industrial I/O); not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary |
| 1.5SMC110A | Same VBR/VC specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W vs. 100 °C/W | Better thermal performance under sustained surge duty, but requires 30% larger PCB area and incompatible footprint | Choose only if board layout allows SMC and thermal derating at elevated ambient temperatures is critical |
Compared with SMAJ110A-E3/52 and 1.5SMC110A, P6SMB110AHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint compatibility, and full 600 W surge rating - making it the preferred choice for space-constrained, automotive-grade transient protection where reliability and manufacturability are co-prioritized.

FAQ
What is the maximum clamping voltage of P6SMB110AHE3_A/H under standard test conditions?
The P6SMB110AHE3_A/H has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 μs waveform peak pulse current of 3.9 A. This value is measured at TA = 25 °C and reflects the upper limit of voltage imposed on the protected circuit during transient events. The clamping behavior remains stable across its operating junction temperature range of –65 °C to +150 °C, with minimal variation due to its low temperature coefficient of VBR (0.107 %/°C).
Is P6SMB110AHE3_A/H suitable for automotive applications?
Yes, P6SMB110AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision notes. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements. Its SMB package, MSL Level 1 rating, and 150 °C maximum junction temperature make it appropriate for under-hood and chassis-mounted automotive electronics, including body control modules and power distribution units.
What does the "_A/H" suffix in P6SMB110AHE3_A/H indicate?
The "_A/H" suffix in P6SMB110AHE3_A/H denotes packaging and revision: "A" specifies the standard revision level per Vishay's internal document control, and "H" indicates 7-inch plastic tape-and-reel delivery with 750 units per reel. This matches the ordering information table in the datasheet, where "H" corresponds to the 7" diameter reel format - critical for SMT line feed compatibility and inventory planning.
How does P6SMB110AHE3_A/H compare to bidirectional TVS diodes like P6SMB110CA?
P6SMB110AHE3_A/H is unidirectional and intended for DC line protection with defined polarity (cathode marked), whereas P6SMB110CA is bidirectional and symmetrical for AC or floating-line applications. The unidirectional version offers lower leakage (<1.0 μA at 94 V) and tighter VBR tolerance versus bidirectional variants, which exhibit doubled leakage limits per note (3) in the datasheet. Use P6SMB110AHE3_A/H where polarity is fixed and leakage must be minimized - such as 24 V supply rail protection in automotive ECUs.
What is the thermal resistance of P6SMB110AHE3_A/H, and how does it affect PCB layout?
P6SMB110AHE3_A/H 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, as specified in the datasheet. This value assumes minimum recommended pad layout; reducing pad size increases thermal impedance and may require derating peak pulse power at elevated ambient temperatures. Layouts must maintain these pad dimensions and avoid thermal isolation to ensure reliable 600 W surge handling without exceeding 150 °C junction temperature.
