Product details
Overview
1.5SMC110AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V at IT = 1 mA), 94.0 V maximum stand-off voltage (VWM), 152 V clamping voltage (VC) at 9.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the 1.5SMC110AHM3/H datasheet, 1.5SMC110AHM3/H pinout, 1.5SMC110AHM3/H application, or 1.5SMC110AHM3/H equivalent, this device is selected for robust ESD and lightning transient suppression where AEC-Q101 qualification, low incremental surge resistance, and MSL Level 1 moisture sensitivity are required in SMC (DO-214AB) packaged TVS solutions.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA leakage at 94.0 V), then rapidly avalanches to clamp transients above VBR. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while the SMC package supports automated placement and meets UL 94 V-0 flammability.
The 1.5SMC110AHM3/H is halogen-free and RoHS-compliant (HM3 suffix), qualified to AEC-Q101 for automotive use, and rated for continuous operation from –65 °C to +150 °C junction temperature. Thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads, enabling reliable power dissipation up to 6.5 W at 50 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1 mA test current - defines precise avalanche onset threshold for repeatable clamping behavior |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 9.9 A - clamping voltage during 1500 W 10/1000 µs surge, limiting downstream voltage stress |
| PPPM | 1500 W - peak pulse power handling capability per single transient event, duty cycle ≤ 0.01 % |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting inrush tolerance |
| TJ max | +150 °C - maximum junction temperature, enabling operation in under-hood automotive environments |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 0.320" x 0.246" footprint and matte tin-plated leads |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with glass-passivated junction, polarity indicated by cathode band. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward conduction mode | Connected to system ground or lower-potential rail when used in unidirectional clamping configuration |
| Cathode | Current exit point; marked with band | Connected to protected line (e.g., 12 V rail); conducts avalanche current to ground during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Halogen-free & RoHS-compliant (HM3) | Meets environmental compliance requirements for modern automotive and industrial PCB assemblies |
| 1500 W peak pulse power (10/1000 µs) | Withstands high-energy surges from load dump or ISO 7637-2 Pulse 5a without degradation |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage overshoot during transient events, protecting sensitive downstream ICs |
| MSL Level 1 (260 °C peak reflow) | Enables standard lead-free reflow soldering without pre-baking or special handling |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp surges above 94 V.

Use Scenario: Adding secondary-side surge protection to 5 V/9 V/12 V USB-C PD adapters before connector output. IC Role / Device Role / Timing Role: Final-line TVS between regulator output and USB port to block conducted transients from downstream devices. Use Value: Prevents latch-up or gate oxide damage in connected smartphones/laptops during hot-plug events. |
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-E3/52 | Lower peak power (600 W), SMB package (smaller footprint), same VBR range but higher VC (183 V @ 3.3 A) | Suitable for space-constrained consumer electronics where 1500 W rating is not required | Select when board area is limited and surge energy is ≤600 W; verify thermal derating on smaller pads |
| 1.5KE110A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or halogen-free certification | Used in legacy industrial power supplies where automated SMT is not available or rework is preferred | Choose only for prototyping or non-automated assembly; lacks automotive qualification and modern environmental compliance |
Compared with 1.5SMC110AHM3/H, SMBJ110A-E3/52 trades peak power and qualification for compactness, while 1.5KE110A sacrifices SMT compatibility and automotive compliance for through-hole serviceability - neither offers drop-in replacement due to package or qualification mismatch.

FAQ
What is the clamping voltage of the 1.5SMC110AHM3/H under a 10/1000 µs surge?
The 1.5SMC110AHM3/H clamps to a maximum of 152 V at 9.9 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88303 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the 1.5SMC110AHM3/H qualified for automotive applications?
Yes, the 1.5SMC110AHM3/H carries the HM3 suffix, indicating halogen-free, RoHS-compliant construction and full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD47, making it suitable for under-hood and body-control module use.
What does the "H" in 1.5SMC110AHM3/H signify?
The "H" denotes the packaging configuration: 7-inch diameter plastic tape and reel, with 850 units per reel. This format is optimized for high-speed pick-and-place assembly and aligns with JEDEC standard MS-013 for SMC devices.
How does the 1.5SMC110AHM3/H differ from bidirectional variants like 1.5SMC110CA?
The 1.5SMC110AHM3/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where current flows in one direction. In contrast, 1.5SMC110CA is bidirectional, symmetric in both directions, and used for AC or differential signal protection - they are not interchangeable without circuit redesign.
What is the maximum operating temperature for the 1.5SMC110AHM3/H?
The 1.5SMC110AHM3/H has a maximum junction temperature (TJ) of +150 °C and an operating storage range of –65 °C to +150 °C. Derating applies above 25 °C ambient; at 50 °C, its power dissipation is rated at 6.5 W with specified pad layout.
