Product details
Overview
1.5SMC110CA-M3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 110 V standoff voltage (VWM), 1500 W peak pulse power rating (10/1000 μs), clamping voltage of 152 V at 9.9 A peak pulse current, and operates across -65 °C to +150 °C junction temperature. It is widely deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC110CA-M3/57T datasheet, 1.5SMC110CA-M3/57T pinout, 1.5SMC110CA-M3/57T application, or 1.5SMC110CA-M3/57T equivalent, this page delivers verified electrical specs, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
The 1.5SMC110CA-M3/57T uses a glass-passivated silicon junction optimized for fast transient response (<1 ps typical) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, making it suitable for AC-coupled or floating signal paths.
It complies with J-STD-020 MSL Level 1 (peak reflow ≤260 °C), supports 8.3 ms single half-sine surge up to 200 A (unidirectional only), and delivers stable clamping performance under repetitive 0.01% duty cycle pulses - critical for lightning-induced transients in telecom and automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 110 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for 12–48 V systems. |
| VC @ IPPM | 152 V - Clamped voltage at 9.9 A peak pulse (10/1000 μs); limits downstream IC stress during ESD/EFT events. |
| PPPM | 1500 W - Peak pulse power handling capacity; sustains high-energy surges per IEC 61000-4-5 Level 4 (4 kV/2 Ω). |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm copper pads; informs PCB thermal layout requirements. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |

Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 22-B102 solderability standards. Bidirectional construction means no cathode/anode marking - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no polarity marking required. |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically identical to Terminal 1; forms symmetrical clamping path across protected line pair. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals or floating buses (e.g., CAN, RS-485) without external polarity management. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 Ω source impedance. |
| Low clamping ratio (VC/VWM = 1.38) | Minimizes overvoltage stress on downstream MOSFETs or microcontrollers during transient events. |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns; eliminates bake requirements pre-assembly. |
| AEC-Q101 qualification option | Available in HM3 variant (e.g., 1.5SMC110CAHM3_A/H); validated for automotive under-hood applications. |
Applications

Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers against field-wiring faults and lightning-induced surges. IC Role / Device Role / Timing Role: Placed between input terminals and ground to clamp common-mode transients before precision ADC front-end. Use Value: Maintains analog accuracy by limiting transient overvoltage to <152 V while adding <0.5 pF capacitance at 0 V bias. |
| Telecom Power Supply Rail | Consumer USB Port Protection |

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 (110 V) and VC (152 V), but lower PPPM = 600 W; SMB package (smaller footprint, higher RθJA = 110 °C/W). | Best suited for space-constrained consumer electronics where surge energy is limited to IEC 61000-4-2 ESD only. | Select when board area is critical and peak surge energy does not exceed 600 W - verify thermal margin with reduced copper pad area. |
| 1.5KE110CA | Same electrical specs (VWM, VC, PPPM), but axial-leaded DO-201 package; higher RθJA (~100 °C/W) and manual assembly requirement. | Used in legacy industrial power supplies and repair kits where through-hole mounting is mandated. | Choose only for through-hole prototyping or replacement in existing DO-201 designs; not recommended for new SMT production. |
Compared with 1.5SMC110CA-M3/57T, SMBJ110CA trades surge robustness for compactness, while 1.5KE110CA sacrifices automated assembly and thermal performance for mechanical compatibility - neither is pin-compatible, but both serve overlapping protection functions in distinct form factors.

FAQ
What is the clamping voltage of the 1.5SMC110CA-M3/57T under maximum rated surge current?
The 1.5SMC110CA-M3/57T clamps to 152 V at its specified peak pulse current of 9.9 A (10/1000 μs waveform). This value is measured per Figure 1 in Vishay document 88303 and represents the maximum voltage seen across the device during a standardized surge event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC110CA-M3/57T suitable for automotive applications?
Yes - the 1.5SMC110CA-M3/57T is halogen-free and RoHS-compliant, and an AEC-Q101-qualified version (1.5SMC110CAHM3_A/H) is available. While the M3/57T variant itself is commercial-grade, its thermal range (-65 °C to +150 °C), surge robustness, and MSL Level 1 rating make it suitable for non-safety-critical automotive subsystems such as body control modules and sensor interfaces.
Does the 1.5SMC110CA-M3/57T have polarity markings?
No - the 1.5SMC110CA-M3/57T is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows installation in either orientation across protected lines, simplifying layout and eliminating risk of reverse placement during assembly.
What is the thermal resistance of the 1.5SMC110CA-M3/57T, and how does it affect PCB layout?
The 1.5SMC110CA-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures under repetitive surges, designers must allocate sufficient copper area and avoid excessive trace length or isolation - undersized pads increase thermal impedance and risk thermal runaway.
How does the 1.5SMC110CA-M3/57T compare to unidirectional variants like 1.5SMC110A-M3/57T?
The 1.5SMC110CA-M3/57T provides symmetrical clamping for AC or floating circuits, whereas the unidirectional 1.5SMC110A-M3/57T includes a cathode band and clamps only in reverse bias. The CA version supports applications like RS-485 or CAN where polarity reversal occurs, while the A version suits DC rails with defined ground reference - both share identical VWM, VC, and PPPM.
