Product details
Overview
1.5SMC110A-M3/57T from Vishay General Semiconductor is a unidirectional 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 at IT = 1.0 mA), 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤152 V at 9.9 A peak pulse current - deployed in automotive power supplies, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the 1.5SMC110A-M3/57T datasheet, 1.5SMC110A-M3/57T pinout, 1.5SMC110A-M3/57T application, or 1.5SMC110A-M3/57T equivalent, this page delivers verified electrical specs, SMC (DO-214AB) package details, clamping behavior under surge conditions, thermal resistance (RθJA = 75 °C/W), and AEC-Q101-qualified halogen-free alternatives.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 94.0 V, it avalanches to limit transient energy. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM), while M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance.
Designed for surface-mount placement on 8.0 mm × 8.0 mm copper pads, it sustains 200 A non-repetitive forward surge (8.3 ms half-sine) and operates from –65 °C to +150 °C. The 1500 W PPPM rating applies only with proper PCB thermal management per Fig. 2 derating curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche onset window for reliable clamping threshold |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 9.9 A - clamped voltage during full 1500 W transient, critical for downstream IC survivability |
| PPPM | 1500 W (10/1000 µs waveform) - peak surge handling capacity under standardized lightning/inductive-switching stress |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance on standard pad layout; dictates derating above 25 °C ambient |
| IFSM | 200 A (8.3 ms half-sine) - surge current capability for unidirectional power-line fault events |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; conducts during forward surge events |
| Cathode | Reverse-biased clamping terminal | Connected to protected line; avalanches into conduction when VLINE > VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V/24 V systems without external series impedance |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage (<1 µA) across temperature and lifetime |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets automotive and industrial environmental compliance requirements without compromising surge robustness |
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT assembly without moisture sensitivity concerns or baking requirements |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load-dump transients up to 35 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between power rail and chassis ground to limit voltage excursions. Use Value: Clamps 35 V load dump to <152 V within nanoseconds, preventing damage to 3.3 V/5 V microcontrollers and CAN transceivers. |
Use Scenario: 4–20 mA current-loop sensors in factory automation subject to ESD and inductive kickback from solenoid switching. IC Role / Device Role / Timing Role: Bidirectional-capable but used unidirectionally across sensor output to ground, absorbing fast transients. Use Value: Sub-1 ns response time and 152 V clamping protect precision op-amps and ADC front-ends without adding capacitance-induced signal distortion. |
| Telecom DC Power Feeding | Consumer Power Adapter Output Protection |
Use Scenario: -48 V DC feeding circuits in base station equipment vulnerable to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary shunt protector on feed line input, coordinated with upstream GDT or MOV. Use Value: 1500 W rating handles multi-kA induced surges; 94 V VWM allows safe operation under normal -48 V ±10 % regulation. |
Use Scenario: Secondary-side 12 V output of wall adapters subjected to user-induced short-circuits and plug-in surges. IC Role / Device Role / Timing Role: Final-stage overvoltage clamp before USB-PD or legacy 5 V regulator inputs. Use Value: Low incremental surge resistance minimizes voltage overshoot during fast-rising faults, preserving downstream USB port ICs. |
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-M3/57T | Lower PPPM (600 W), same VBR range, SMB (DO-214AA) package - 30 % smaller footprint, lower thermal mass | Preferred for space-constrained consumer electronics where 600 W surge margin suffices | Select when board area is critical and peak surge exposure is below IEC 61000-4-5 Level 3 |
| 1.5KE110A-T | Through-hole TO-204AE (DO-15), identical VBR/VC, 1500 W rating - higher RθJA (~100 °C/W), no MSL Level 1 rating | Used in legacy industrial controls requiring manual assembly or high-vibration mechanical retention | Choose only if SMT is unavailable or mechanical robustness outweighs thermal performance and reflow compatibility |
Compared with 1.5SMC110A-M3/57T, SMBJ110A-M3/57T trades surge capacity for compactness, while 1.5KE110A-T sacrifices thermal efficiency and modern process compliance for through-hole reliability - making 1.5SMC110A-M3/57T optimal for AEC-Q101-aligned, high-power SMT designs.

FAQ
What is the maximum clamping voltage of the 1.5SMC110A-M3/57T under a 10/1000 µs surge?
The 1.5SMC110A-M3/57T clamps to a maximum of 152 V when subjected to its rated 9.9 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and represents the upper bound of voltage seen by downstream circuitry during worst-case transient events - critical for ensuring compatibility with 150 V-rated components.
Is the 1.5SMC110A-M3/57T suitable for automotive applications?
Yes - the 1.5SMC110A-M3/57T is halogen-free and RoHS-compliant (M3 suffix), and an AEC-Q101-qualified version is available under ordering code 1.5SMC110AHM3_A/H. While the base 1.5SMC110A-M3/57T itself is commercial-grade, its thermal rating (TJ max = +150 °C), surge robustness (1500 W), and MSL Level 1 reflow compatibility make it suitable for under-hood and body-control module designs pending qualification confirmation.
What does the "-M3/57T" suffix indicate in 1.5SMC110A-M3/57T?
The "M3" denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, while "/57T" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This suffix distinguishes it from E3 (standard RoHS) and HE3/HM3 (AEC-Q101) variants, and confirms suitability for lead-free SMT assembly with industry-standard reel logistics.
How does the 1.5SMC110A-M3/57T compare to bidirectional TVS diodes like 1.5SMC110CA-M3/57T?
The 1.5SMC110A-M3/57T is unidirectional and features a cathode band for polarity-sensitive placement, whereas 1.5SMC110CA-M3/57T is bidirectional with no polarity marking and symmetric clamping in both directions. Use 1.5SMC110A-M3/57T on DC rails where reverse voltage is blocked by upstream diodes; choose the CA variant only for AC-coupled or floating signal lines requiring symmetrical protection.
What is the thermal resistance of the 1.5SMC110A-M3/57T, and how does it affect derating?
The 1.5SMC110A-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 Figure 2. This means power dissipation must be linearly derated above 25 °C ambient - e.g., at 85 °C ambient, maximum continuous power drops to ~3.9 W - critical for sustained surge duty cycles or high-temperature enclosure designs.
