Product details
Overview
1.5SMC110AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V), 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤152 V at 9.9 A, making it suitable for automotive power rail and industrial sensor interface protection.
For engineers reviewing the 1.5SMC110AHM3_A/H datasheet, 1.5SMC110AHM3_A/H pinout, 1.5SMC110AHM3_A/H application, or 1.5SMC110AHM3_A/H equivalent, this device delivers AEC-Q101 qualification, SMC (DO-214AB) package compatibility, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB designs.
Technical Context
This unidirectional TVS operates with a standoff voltage of 94.0 V and exhibits ≤1.0 µA reverse leakage at VWM, ensuring minimal standby current draw in protected circuits. Its fast response time (<1 ns) and low clamping ratio (VC/VBR ≈ 1.38) enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device uses a glass-passivated silicon junction and is rated for TJ = –65 °C to +150 °C operation. Thermal resistance is RθJA = 75 °C/W (typ.) on standard 8.0 mm × 8.0 mm copper pads, supporting 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 - Ensures consistent avalanche initiation across production units; defines minimum overvoltage threshold before clamping begins. |
| VWM | 94.0 V - Maximum continuous reverse operating voltage; sets safe DC/AC bias limit without significant leakage. |
| VC @ IPPM | ≤152 V - Clamped voltage during 9.9 A transient; determines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 1500 W - Peak pulse power handling (10/1000 µs waveform); supports high-energy surge immunity per IEC 61000-4-5. |
| IPPM | 9.9 A - Peak pulse current capability; directly correlates with surge energy absorption (W = V × I × t). |
| TJ max. | +150 °C - Junction temperature limit; enables operation in under-hood automotive or high-ambient industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 0.320" body length; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Cathode indicated by band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (unidirectional) | Connected to ground or lower-potential node; completes current path during reverse-biased transient clamping. |
| Cathode | Protected line connection terminal | Connected to the line being protected (e.g., 12 V rail, CAN bus, sensor output); carries surge current into ground via anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for under-hood and ADAS applications. |
| 1500 W peak pulse power | Withstands high-energy transients per ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 without degradation. |
| Low clamping voltage (152 V) | Minimizes voltage overshoot on protected nodes, preserving margin for 100 V-rated components like automotive gate drivers. |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without baking; eliminates moisture-related popcorning risk during manufacturing. |
| Glass passivated junction | Improves long-term stability and reduces parameter drift under thermal stress versus epoxy-passivated alternatives. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp transients above 94 V. Use Value: Limits peak voltage to ≤152 V during 1500 W surges, safeguarding 100 V-rated DC-DC controllers and microcontrollers. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors from field wiring surges. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS shunting induced transients before they reach precision amplifier inputs. Use Value: Maintains signal integrity with <1.0 µA leakage at 94 V, avoiding offset errors in µA-level sensor current loops. |
| Telecom Line Interface | Motor Drive Gate Protection |
Use Scenario: Guarding RS-485 transceivers connected to long outdoor cables susceptible to lightning coupling. IC Role / Device Role / Timing Role: Bidirectional-capable series (though 1.5SMC110AHM3_A/H is unidirectional) used in pairs; this part serves as ground-referenced clamp. Use Value: Fast <1 ns response ensures clamping occurs before transceiver ESD structures fail, meeting IEC 61000-4-5 surge immunity. |
Use Scenario: Protecting high-side N-channel MOSFET gates driven by isolated gate drivers in BLDC inverters. IC Role / Device Role / Timing Role: Clamp gate-source voltage spikes caused by Miller coupling during high dV/dt switching events. Use Value: Withstands 200 A non-repetitive forward surge (IFSM), preventing gate oxide rupture during fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A | Same VBR range (105–116 V), but lower PPPM = 400 W and smaller SMA package (DO-214AC). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5 or IEC 61000-4-5 Level 4. | Select when board space is constrained and surge threat level is Class 2 or lower. |
| 1.5KE110A | Through-hole TO-204AA (DO-41) package; identical electrical specs but incompatible with SMT assembly. | Requires manual or wave-solder placement; not viable for fully automated high-volume production. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ110A and 1.5KE110A, the 1.5SMC110AHM3_A/H uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge capacity - enabling drop-in use in automotive production lines without layout or reliability compromises.

FAQ
What is the clamping voltage of the 1.5SMC110AHM3_A/H under maximum surge conditions?
The 1.5SMC110AHM3_A/H clamps to a maximum of 152 V when subjected to its rated peak pulse current of 9.9 A (10/1000 µs waveform). This value is measured per standard test conditions and reflects the upper bound of voltage seen by downstream circuitry during worst-case transient events, ensuring compatibility with 100 V-rated components in automotive and industrial applications.
Is the 1.5SMC110AHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC110AHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix). Its construction, thermal performance (TJ max. = +150 °C), and surge capability meet requirements for engine control units, body electronics, and ADAS modules where reliability under thermal and electrical stress is mandatory.
What does the "_A/H" suffix mean in 1.5SMC110AHM3_A/H?
The "_A" denotes the revision code per Vishay's ordering nomenclature, indicating the device belongs to the AEC-Q101 qualified variant group for 1.5SMC6.8A to 1.5SMC220A. The "/H" specifies packaging in 7-inch diameter plastic tape and reel with 850 units per reel - a standard logistics format for SMT assembly lines.
How does the 1.5SMC110AHM3_A/H differ from bidirectional TVS diodes in the same series?
The 1.5SMC110AHM3_A/H is unidirectional, meaning it conducts only during reverse-bias transients and blocks forward current beyond ~3.5 V. Bidirectional variants (e.g., 1.5SMC110CA) conduct symmetrically in both directions and lack a polarity band. This makes the 1.5SMC110AHM3_A/H ideal for DC power line protection where polarity is fixed, while bidirectional types suit AC or differential signal lines like RS-485.
What is the maximum operating temperature for the 1.5SMC110AHM3_A/H?
The 1.5SMC110AHM3_A/H has a specified junction temperature range of –65 °C to +150 °C. At ambient temperatures up to +125 °C, derating per Figure 2 in the datasheet applies, but the device maintains full functionality within its thermal limits when mounted on recommended 8.0 mm × 8.0 mm copper pads - critical for under-hood automotive deployments.
