Product details
Overview
SMBJ110CD-M3/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 110 V stand-off voltage (VWM), 124–133 V breakdown voltage (VBR), 174 V clamping voltage (VC) at 3.45 A peak pulse current, and 600 W peak pulse power rating for 10/1000 μs waveform - used to protect I/O lines and power rails in industrial sensor interfaces and telecom power supplies.
For engineers reviewing the SMBJ110CD-M3/H datasheet, SMBJ110CD-M3/H pinout, SMBJ110CD-M3/H application, or SMBJ110CD-M3/H equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, MSL Level 1 reflow compatibility, and RoHS-compliant halogen-free construction per JESD201 Class 2 whisker testing.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled signal paths and full-bridge rectifier inputs. Its low incremental surge resistance and fast response time (<1 ns) ensure minimal let-through energy during ESD or lightning-induced surges.
The device is rated for 600 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, derated linearly above 25 °C ambient using RθJA = 125 °C/W on minimum pad layout. Junction temperature is limited to 150 °C, with storage range from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse working voltage before clamping begins |
| VBR min/max | 124 V / 133 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 174 V at 3.45 A - clamping voltage defines worst-case overvoltage seen by protected circuitry |
| PPPM | 600 W - peak transient energy absorption capability for standardized 10/1000 μs surge waveform |
| ID @ VWM | 0.5 μA - ultra-low leakage preserves signal integrity and battery life in high-impedance circuits |
| TJ max | +150 °C - enables reliable operation in enclosed industrial enclosures without forced cooling |
| MSL Level | Level 1 (J-STD-020) - supports standard SMT reflow up to 260 °C peak without preconditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA-M3/5B | Same VWM/VBR/VC specs; differs only in tape-and-reel packaging (5K vs. 750 pcs/reel) and MSL handling code | No functional difference - identical electrical and thermal performance in circuit | Select when higher volume reels or alternate carrier tape format required |
| SMCJ110CA | Higher 1500 W PPPM rating; larger SMC (DO-214AB) package; same VWM/VBR but lower VC (187 V @ 5.5 A) | Used where higher surge energy capacity is needed and PCB space allows larger footprint | Choose for enhanced robustness in high-surge environments like outdoor power supplies or EV charging stations |
Compared with SMBJ110CD-M3/H, SMBJ110CA-M3/5B offers identical protection performance in alternate packaging, while SMCJ110CA provides 2.5× higher pulse power at the cost of larger board area and slightly higher clamping voltage - enabling trade-offs between surge margin and layout density.

FAQ
What is the clamping voltage of SMBJ110CD-M3/H and how is it measured?
The SMBJ110CD-M3/H has a maximum clamping voltage (VC) of 174 V, measured at its peak pulse current (IPPM) of 3.45 A under the standardized 10/1000 μs double-exponential surge waveform. This value represents the highest voltage that will appear across the device during a defined transient event, directly limiting overvoltage stress on downstream components. The test condition is specified in the Vishay datasheet Document Number 87606 and applies equally in both directions due to its bidirectional construction.
Is SMBJ110CD-M3/H suitable for bidirectional signal line protection?
Yes, SMBJ110CD-M3/H is explicitly designed for bidirectional protection, as indicated by the "CD" suffix and confirmed in the Vishay datasheet. It exhibits symmetrical breakdown and clamping characteristics in both polarities, making it ideal for safeguarding AC-coupled interfaces such as RS-485, CAN FD physical layers, or audio differential pairs where transients may occur with either polarity. No external polarity alignment is needed during placement.
What is the thermal resistance and how does it affect SMBJ110CD-M3/H's power handling?
SMBJ110CD-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended pad layout. This means each watt of steady-state power dissipation raises the junction temperature by 125 °C above ambient - limiting continuous power to 1.0 W at 25 °C. For transient events, the 600 W rating applies only for short durations (≤50 ms), with derating required above 25 °C per Figure 2 in the datasheet.
Does SMBJ110CD-M3/H meet RoHS and halogen-free requirements?
Yes, SMBJ110CD-M3/H complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard. The "M3" suffix confirms industrial-grade construction with matte tin-plated leads, JESD201 Class 2 whisker resistance, and UL 94 V-0 molding compound - fully documented in Vishay Document Number 87606, Revision 09-Jan-2024.
How does the ±3.5 % VBR tolerance of SMBJ110CD-M3/H benefit circuit design?
The ±3.5 % breakdown voltage tolerance (124–133 V at 1 mA) ensures tight distribution of turn-on voltage across production units, reducing the need for oversized voltage margins in protected circuit design. This allows engineers to select downstream ICs with lower absolute maximum ratings while maintaining safety margin, improving system-level efficiency and enabling smaller, more cost-effective protection schemes without sacrificing reliability.
