Product details
Overview
P6SMB110CAHM3_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), 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB110CAHM3_A/I datasheet, P6SMB110CAHM3_A/I pinout, P6SMB110CAHM3_A/I application, or P6SMB110CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables fast transient response under repetitive 0.01% duty-cycle surges.
The device is rated for TJ = -65 °C to +150 °C operation and meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C). Its SMB (DO-214AA) package supports automated placement and provides UL 94 V-0 flammability compliance with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 105–116 V at 1.0 mA - Confirmed avalanche onset range; ensures reliable triggering during overvoltage events. |
| VC (Clamping Voltage) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity for standardized lightning/surge waveforms; critical for IEC 61000-4-5 compliance. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +150 °C - Enables use in under-hood automotive or high-temperature industrial environments without derating. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for thermal management. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically regardless of orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Accepts surge current from either direction; connects to line being protected. |
| Cathode | Transient current exit (bidirectional) | Completes low-impedance path to ground or return rail during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and infotainment systems. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surge events without degradation when mounted on recommended 5.0 mm × 5.0 mm copper pads. |
| Halogen-free & RoHS-compliant | HM3 suffix confirms halogen-free molding compound and lead finish - meets EU ELV and China RoHS requirements for green manufacturing. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profiles up to 260 °C - eliminates baking requirements and simplifies SMT production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V), VC = 152 V, but rated for 600 W with larger SMBJ package (DO-214AB); RθJA = 85 °C/W vs. 100 °C/W. | Higher thermal mass allows slightly higher sustained surge duty cycles; less space-efficient than SMB footprint. | Select SMBJ110CA only if board layout permits larger DO-214AB footprint and improved thermal performance is required. |
| 1.5SMC110CA | Same electrical specs (VWM = 94 V, VC = 152 V), but in larger SMC (DO-214AB) package; rated for same 600 W, RθJA = 75 °C/W. | Lower thermal resistance supports higher average power dissipation; not compatible with SMB land pattern. | Choose 1.5SMC110CA when thermal constraints dominate and PCB real estate allows SMC footprint. |
Compared with SMBJ110CA and 1.5SMC110CA, P6SMB110CAHM3_A/I offers identical clamping performance in the smallest standardized SMB (DO-214AA) footprint, enabling high-density layouts while maintaining AEC-Q101 qualification and halogen-free compliance - ideal for space-constrained automotive and industrial modules.

FAQ
What does the "CA" suffix indicate in P6SMB110CAHM3_A/I?
The "CA" suffix in P6SMB110CAHM3_A/I denotes a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., P6SMB110A), this device clamps voltage transients equally in both polarities - essential for protecting AC-coupled or differential signal lines where polarity reversal may occur during surges.
Is P6SMB110CAHM3_A/I suitable for automotive applications?
Yes, P6SMB110CAHM3_A/I is AEC-Q101 qualified (indicated by the HM3 suffix and "_B" or "_D" AEC-Q101 grade codes in Vishay documentation), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces where reliability under temperature cycling and surge stress is mandatory.
How does the SMB (DO-214AA) package of P6SMB110CAHM3_A/I compare to SMC or SMBJ alternatives?
The SMB (DO-214AA) package of P6SMB110CAHM3_A/I measures 3.94 mm × 2.20 mm × 1.52 mm - smaller than SMC (DO-214AB) and SMBJ (DO-214AB) packages. This enables higher board density, though with higher RθJA (100 °C/W vs. ~75–85 °C/W), requiring adherence to Vishay's 5.0 mm × 5.0 mm copper pad recommendation for thermal performance.
What is the maximum clamping voltage of P6SMB110CAHM3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB110CAHM3_A/I is 152 V at a peak pulse current (IPPM) of 3.9 A with a 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Does P6SMB110CAHM3_A/I require special handling or baking before reflow soldering?
No, P6SMB110CAHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and withstands peak reflow temperatures up to 260 °C without preconditioning. No baking or dry-pack handling is required - simplifying SMT line integration and reducing process overhead.
