Product details
Overview
P6SMB110CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 110 V standoff voltage (VWM), 125 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB110CAHE3_A/I datasheet, P6SMB110CAHE3_A/I pinout, P6SMB110CAHE3_A/I application, or P6SMB110CAHE3_A/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) under PCB pad constraints.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 10/1000 μs surge rating reflects standardized lightning and inductive-switching transient immunity.
The device is rated for continuous operation from –65 °C to +150 °C junction temperature and meets J-STD-020 MSL Level 1, supporting lead-free reflow up to 260 °C peak. Its 20 °C/W junction-to-lead thermal resistance supports localized heat dissipation during repetitive surges when mounted per recommended 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 105–116 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during full-rated 10/1000 μs transient |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability for standardized surge waveforms without failure |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient air; requires minimum 0.2" × 0.2" copper pads for rated derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V), VC (152 V), and PPPM (600 W); identical SMB package but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5KE110CA | Higher power (1500 W), larger DO-204AB package, slower response due to higher junction capacitance | Requires PCB layout change; better for high-energy but lower-frequency surges (e.g., AC mains) | Choose only if system demands >600 W surge handling and board space allows larger footprint |
Compared with SMBJ110CA and 1.5KE110CA, P6SMB110CAHE3_A/I uniquely combines AEC-Q101 qualification, SMB footprint, and precise 110 V bidirectional clamping - making it optimal for space-constrained automotive and industrial designs requiring certified reliability.

FAQ
What does the "CA" suffix indicate in P6SMB110CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB110CAHE3_A/I provides symmetrical clamping in both polarities - essential for protecting AC-coupled or differential signal lines like CAN, RS-485, or Ethernet PHY interfaces without polarity concerns. This differs from unidirectional variants (e.g., P6SMB110A) that require correct cathode orientation.
Is P6SMB110CAHE3_A/I suitable for automotive applications?
Yes, P6SMB110CAHE3_A/I is AEC-Q101 qualified, verified for automotive-grade reliability including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. Its –65 °C to +150 °C operating range and MSL Level 1 rating make it appropriate for engine control units, ADAS sensors, and body electronics where sustained thermal and mechanical stress occurs.
What is the maximum clamping voltage of P6SMB110CAHE3_A/I under rated surge conditions?
The maximum clamping voltage (VC) of P6SMB110CAHE3_A/I is 152 V at a peak pulse current (IPPM) of 3.9 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during a full-rated transient event - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of P6SMB110CAHE3_A/I compare to larger TVS packages like DO-204AB?
The SMB (DO-214AA) package of P6SMB110CAHE3_A/I measures 4.57 mm × 3.94 mm × 2.20 mm - significantly smaller than DO-204AB (e.g., 1.5KE series). While both deliver 600 W peak power, the SMB enables high-density layouts in space-constrained applications such as automotive ECUs and portable telecom equipment, without sacrificing surge capability when mounted per recommended 0.2" × 0.2" copper pads.
Does P6SMB110CAHE3_A/I require special PCB layout considerations?
Yes, P6SMB110CAHE3_A/I requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated thermal performance and 600 W surge capability. Smaller pads increase RθJA beyond the specified 100 °C/W, risking thermal runaway during repetitive transients. Trace width and grounding must also minimize inductance to preserve fast response (<1 ns).
