Product details
Overview
P6SMB110CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 94.0 V standoff voltage (VWM), 105–116 V breakdown voltage (VBR at 1 mA), 152 V maximum 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, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the P6SMB110CAHM3/H datasheet, P6SMB110CAHM3/H pinout, P6SMB110CAHM3/H application, or P6SMB110CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It responds within nanoseconds to transient overvoltages induced by inductive switching or ESD events, limiting voltage across protected circuit nodes to ≤152 V at 3.9 A IPPM.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, typical) and RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance under repetitive 0.01% duty cycle stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 94.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown) | 105–116 V at 1 mA - Guaranteed voltage range where device enters avalanche conduction; ensures predictable turn-on |
| VC (Clamping) | 152 V at 3.9 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe IC voltage margin |
| PPPM | 600 W - Peak pulse power handling per 10/1000 μs waveform; supports robust protection against lightning-induced surges |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt surge energy before reaching signal conditioning ICs.

| Telecom Power Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding PoE-powered Ethernet PHYs and DC-DC converters from induced surges on 48 V supply rails. IC Role / Device Role / Timing Role: Secondary-level TVS on mid-span power delivery path, coordinated with primary GDT or MOV stages. Use Value: Fast response (<1 ns) and low VC prevent overvoltage damage to isolated DC-DC controllers rated for 60 V input max. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Across-motor terminals to clamp inductive kickback before it reaches MCU-driven H-bridge drivers. Use Value: 152 V clamping protects 200 V-rated MOSFETs and eliminates false triggering of overvoltage protection in motor driver ICs. |
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/VBR/VC specs but lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 3 or automotive load dump | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating at elevated ambient temperatures |
| 1.5SMC110CA | Same electrical ratings but larger SMC (DO-214AB) package, higher thermal mass, RθJA = 60 °C/W | Better sustained power handling and lower junction temperature rise during repetitive surges | Prefer for high-reliability industrial systems requiring >100,000 surge cycles or operation above 85 °C ambient |

FAQ
What does the "CA" suffix indicate in P6SMB110CAHM3/H?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB110CAHM3/H conducts and clamps symmetrically in both polarities, unlike unidirectional variants (e.g., P6SMB110AHM3/H). This makes P6SMB110CAHM3/H ideal for AC-coupled signal lines, differential buses like CAN, and any application where voltage transients may swing positive or negative relative to ground.
Is P6SMB110CAHM3/H suitable for automotive applications?
Yes - P6SMB110CAHM3/H carries the HM3 suffix, confirming halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101, making P6SMB110CAHM3/H appropriate for under-hood and cabin electronics such as body control modules and sensor front-ends.
What is the maximum clamping voltage of P6SMB110CAHM3/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB110CAHM3/H is 152 V, measured at a peak pulse current (IPPM) of 3.9 A using the standardized 10/1000 μs double-exponential waveform. This value defines the worst-case voltage imposed on protected circuitry during surge events and must be compared against the absolute maximum ratings of downstream ICs.
How does the SMB package of P6SMB110CAHM3/H compare to SMA or SMC in terms of thermal performance?
P6SMB110CAHM3/H in SMB (DO-214AA) offers RθJA = 100 °C/W (typical), higher than SMC's ~60 °C/W but lower than SMA's ~125 °C/W. Its thermal design assumes mounting on 0.2" × 0.2" copper pads per terminal - providing adequate dissipation for 600 W single-pulse events, though repetitive surges require careful PCB layout and ambient temperature management.
Does P6SMB110CAHM3/H require orientation during PCB placement?
No - P6SMB110CAHM3/H is a bidirectional TVS diode with no polarity marking; the device functions identically regardless of orientation on the PCB. Unlike unidirectional variants (which feature a cathode band), P6SMB110CAHM3/H has no anode/cathode distinction and may be placed in either direction without affecting clamping behavior or circuit protection.
