Product details
Overview
1.5SMC110A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features a 110 V breakdown voltage (VBR = 105–116 V at 1.0 mA), 94.0 V stand-off voltage (VWM), clamps transients to ≤152 V at 9.9 A peak pulse current (IPPM), and delivers 1500 W peak pulse power with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC110A-M3/9AT datasheet, 1.5SMC110A-M3/9AT pinout, 1.5SMC110A-M3/9AT application, or 1.5SMC110A-M3/9AT equivalent, this device supports robust overvoltage protection in DC power rails, automotive ECUs, and industrial I/O interfaces where fast response (<1 ns), low clamping ratio (152 V / 94 V ≈ 1.62), and AEC-Q101-qualified halogen-free construction are critical selection criteria.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 94.0 V), but triggers into low-impedance conduction when reverse voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surges.
Thermally, it uses a DO-214AB package with RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), enabling effective heat dissipation on standard 8.0 mm × 8.0 mm copper pads. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 94.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 100 V nominal systems. |
| VBR (min/max) | 105–116 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable triggering across temperature and unit variation. |
| VC @ IPPM | ≤152 V at 9.9 A - Clamping voltage under 10/1000 µs surge; limits stress on protected ICs to safe levels. |
| PPPM | 1500 W - Peak pulse power handling capability; supports lightning-induced transients per IEC 61000-4-5 Level 4. |
| IPPM | 9.9 A - Peak pulse current capacity with 10/1000 µs waveform; determines minimum series impedance required for coordination. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and enclosed industrial enclosures. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with cathode band marking; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated. Cathode identified by a single band on the body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line (e.g., +12 V rail); conducts avalanche current to ground during overvoltage events. |
| Anode (unmarked end) | Reference/return node | Typically tied to system ground or low-impedance return path; completes shunt conduction loop during transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 surge immunity requirements for industrial and automotive applications. |
| Clamping voltage ≤152 V at 9.9 A | Provides 1.62× overvoltage margin relative to 94.0 V stand-off, ensuring downstream 100 V-rated components remain within safe operating area. |
| Fast response time (<1 ns) | Activates before sensitive logic or analog circuits can be damaged by nanosecond-scale ESD or switching transients. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets global environmental regulations and JESD201 Class 2 whisker resistance for long-term reliability in harsh thermal cycling environments. |
| AEC-Q101 qualified option available | Supports automotive-grade qualification path; this M3 variant is commercial-grade but shares identical die and package design with qualified versions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52T | Lower peak power (600 W), same VWM/VBR range, SMB (DO-214AA) package (smaller footprint, higher RθJA = 85 °C/W). | Not suitable for 1500 W surge events; limited to lower-energy IEC 61000-4-2/4-4 applications. | Select only if space-constrained layout and surge energy is ≤600 W; verify thermal derating at elevated ambient temperatures. |
| 1.5KE110A | Through-hole TO-204AE (DO-201AE) package, identical electrical specs but larger size and manual assembly requirement. | Used where board-level reworkability or high-vibration mechanical retention is prioritized over SMT automation. | Choose for legacy designs or ruggedized military/aerospace systems requiring axial-leaded robustness and no reflow dependency. |
Compared with SMBJ110A-E3/52T and 1.5KE110A, the 1.5SMC110A-M3/9AT uniquely balances 1500 W surge capability, SMC surface-mount compatibility, halogen-free compliance, and commercial-grade cost-making it optimal for high-volume automotive and industrial power supply designs requiring automated assembly and regulatory alignment.

FAQ
What is the maximum clamping voltage of the 1.5SMC110A-M3/9AT under a 10/1000 µs surge?
The 1.5SMC110A-M3/9AT clamps to a maximum of 152 V when subjected to its rated peak pulse current of 9.9 A with a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88303, page 2) and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the 1.5SMC110A-M3/9AT AEC-Q101 qualified?
No, the 1.5SMC110A-M3/9AT is not AEC-Q101 qualified. It carries the M3 suffix indicating halogen-free, RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, select the HM3 variant (e.g., 1.5SMC110AHM3_A/I), which shares identical electrical specs but undergoes additional automotive stress testing and traceability controls.
What does the "-M3/9AT" suffix indicate in 1.5SMC110A-M3/9AT?
The "M3" denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow capability. The "/9AT" specifies packaging in a 13-inch diameter plastic tape and reel containing 3500 units - optimized for high-speed SMT placement equipment.
Can the 1.5SMC110A-M3/9AT be used in bidirectional applications?
No, the 1.5SMC110A-M3/9AT is strictly unidirectional. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC110CA). Using this part in reverse-biased configurations risks permanent failure, as its internal structure lacks symmetrical avalanche capability in both directions.
What is the thermal resistance from junction to ambient for the 1.5SMC110A-M3/9AT?
The typical thermal resistance from junction to ambient (RθJA) for the 1.5SMC110A-M3/9AT is 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes still air conditions and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures.
