Product details
Overview
P6SMB110CAHM3/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 capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB110CAHM3/I datasheet, P6SMB110CAHM3/I pinout, P6SMB110CAHM3/I application, or P6SMB110CAHM3/I equivalent, key selection criteria include bidirectional transient suppression capability, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) for board-level surge resilience.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping positive and negative transients above its breakdown voltage (VBR min = 105 V, max = 116 V at 1 mA). Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog and digital inputs against ESD and inductive switching spikes.
Rated for TJ = –65 °C to +150 °C operation and qualified to AEC-Q101 (HM3 suffix), the P6SMB110CAHM3/I supports automotive-grade reliability. Its SMB (DO-214AA) package provides low-profile mounting, meets UL 94 V-0 flammability, and is compatible with automated SMT assembly per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping threshold across production lots. |
| 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 transient energy absorption capability under standardized 10/1000 μs waveform; enables robust surge immunity. |
| ID (Reverse Leakage) | <1.0 μA at 94.0 V - Minimal standby current draw; avoids signal integrity degradation or battery drain in always-on systems. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad design (0.2" × 0.2") for thermal management. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads, RoHS-compliant and halogen-free (HM3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts during negative surges; symmetrical with cathode for bidirectional clamping. |
| Cathode | Transient current entry (positive half-cycle) | Conducts during positive surges; forms matched pair with anode for full-wave protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3) | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges without degradation when mounted per recommended pad layout. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs - e.g., keeps microcontroller I/O pins below absolute maximum ratings during transients. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without preconditioning or special handling. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation reduces fire risk in high-reliability power and telecom infrastructure equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA | Same VWM (94 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without derating | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with reduced copper area. |
| 1.5KE110CA | Same VWM/VC specs, through-hole DO-201 package, higher IFSM (200 A), but no AEC-Q101 qualification | Not suitable for automotive SMT production; requires wave soldering and larger PCB real estate | Choose for legacy industrial designs where manual assembly or higher surge current margin is prioritized over AEC-Q101 compliance. |
Compared with SMAJ110CA and 1.5KE110CA, the P6SMB110CAHM3/I uniquely combines AEC-Q101 qualification, 600 W surge rating, and SMB SMT compatibility - making it the preferred choice for new automotive and high-reliability industrial designs requiring drop-in manufacturability and validated automotive stress testing.

FAQ
What does the "CA" suffix indicate in P6SMB110CAHM3/I?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB110CAHM3/I clamps voltage transients equally in both polarities, unlike unidirectional variants (e.g., P6SMB110A). This makes it ideal for AC-coupled lines, differential buses like CAN, and any application where polarity reversal or bipolar surges must be suppressed without external circuitry.
Is P6SMB110CAHM3/I qualified for automotive use?
Yes, the "HM3" suffix confirms that P6SMB110CAHM3/I is halogen-free, RoHS-compliant, and AEC-Q101 qualified - verified for operation across –65 °C to +150 °C junction temperature and subjected to stress tests including HTOL, temperature cycling, and ESD. It is approved for use in engine control units, body control modules, and ADAS sensor subsystems.
What is the maximum clamping voltage of P6SMB110CAHM3/I under surge conditions?
The P6SMB110CAHM3/I has a maximum clamping voltage (VC) of 152 V at a peak pulse current (IPPM) of 3.9 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events.
How does the SMB (DO-214AA) package of P6SMB110CAHM3/I compare to SMA or SMC packages?
The SMB package of P6SMB110CAHM3/I offers a balanced trade-off: smaller than SMC (DO-214AB) but higher power handling than SMA (DO-214AC). At 600 W PPPM, it delivers 50% more surge capability than typical SMA devices while maintaining compatibility with standard 8-mm tape-and-reel feeders and reflow profiles - unlike SMC, which may require wider stencils or slower ramp rates.
Can P6SMB110CAHM3/I replace P6SMB110A in a design?
No - P6SMB110CAHM3/I is bidirectional, whereas P6SMB110A is unidirectional and includes a cathode band marking. Substituting them requires verifying circuit topology: P6SMB110CAHM3/I works across AC paths or differential signals without polarity concern, but P6SMB110A must be oriented correctly and cannot suppress negative-going transients alone. Layout changes and functional validation are required.
