Product details
Overview
SM15T200A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 274 V clamping voltage at 5.5 A peak pulse current, and 171 V stand-off voltage. It protects MOSFETs, I/O lines, and sensor signal paths in automotive and industrial power electronics against lightning-induced and switching transients.
For engineers reviewing the SM15T200A-M3/57T datasheet, SM15T200A-M3/57T pinout, SM15T200A-M3/57T application, or SM15T200A-M3/57T equivalent, key selection criteria include verified clamping performance at 5.5 A IPPM, unidirectional polarity with cathode band marking, halogen-free RoHS compliance (M3 suffix), and SMC package thermal resistance of 75 °C/W junction-to-ambient.
Technical Context
This TVS diode operates as a voltage-clamped overvoltage protection device, triggering when reverse voltage exceeds 190–210 V breakdown range (VBR at 1 mA). Its low-inductance SMC package enables fast response to transient threats up to 1500 W, with failure mode defined as short-circuit under overstress.
Designed for high-source-impedance circuits, it delivers stable clamping at 274 V (VC) under 10/1000 μs waveform and supports 200 A non-repetitive forward surge (IFSM). Thermal design requires attention to pad layout-rated per 8.0 mm × 8.0 mm copper pads-and junction temperature limits (−65 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains lightning and inductive switching surges without degradation |
| Stand-off Voltage (VWM) | 171 V - maximum continuous reverse voltage before leakage exceeds 1 μA |
| Breakdown Voltage (VBR) | 190–210 V at 1 mA - precise threshold for reliable turn-on during overvoltage events |
| Clamping Voltage (VC) | 274 V at 5.5 A IPPM - limits downstream voltage stress during transient conduction |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 75 °C/W RθJA |
| Polarity | Unidirectional - cathode marked by band; blocks forward current, clamps reverse transients |
| RoHS / Halogen Status | M3 suffix - halogen-free, RoHS-compliant, JESD201 Class 2 whisker tested |
Pinout & Package
SM15T200A-M3/57T uses the SMC (DO-214AB) package: molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, and polarity indicated by a cathode band on the unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line's low-side or ground reference; completes clamping loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ200A | Same 200 V VWM, but 250 V VC at 5.2 A; 600 W rating (SMA package) | Lower power handling; suitable only for sub-1 kV threat environments | Select SMAJ200A only if board space is constrained and surge threat level is ≤1 kV |
| ON Semiconductor 1.5SMC200A | Identical 200 V VWM and 274 V VC, but 1.5 kW rating in same SMC package; RoHS/E3 compliant | No halogen-free option; not qualified to JESD201 Class 2 whisker test | Choose 1.5SMC200A for cost-sensitive commercial designs where halogen-free is not mandated |

FAQ
What is the clamping voltage of SM15T200A-M3/57T at its rated peak pulse current?
The SM15T200A-M3/57T has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at 5.5 A peak pulse current (IPPM). This value is measured under standardized test conditions with 8.0 mm × 8.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events. The SM15T200A-M3/57T maintains this clamping performance across its operating temperature range.
Is SM15T200A-M3/57T suitable for automotive applications?
The SM15T200A-M3/57T is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 for whisker resistance-but it is not AEC-Q101 qualified. For automotive use, Vishay offers the HM3 variant (e.g., SM15T200AHM3_A/H). The SM15T200A-M3/57T is approved for commercial and industrial applications; designers requiring automotive qualification must specify the HM3 suffix and revision-coded part number.
What does the "M3" suffix mean in SM15T200A-M3/57T?
The "M3" suffix in SM15T200A-M3/57T indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that meet JESD201 Class 2 whisker testing requirements. It distinguishes the part from the "E3" (RoHS-compliant, non-halogen-free) and "HM3" (AEC-Q101 qualified + halogen-free) variants. The "57T" denotes 7-inch tape-and-reel packaging with 850 units per reel.
How does SM15T200A-M3/57T differ from bidirectional TVS diodes like SM15T200CA?
The SM15T200A-M3/57T is unidirectional and features a cathode band for polarity identification; it blocks forward current and clamps reverse transients. In contrast, SM15T200CA is bidirectional, has no polarity marking, and clamps transients of either polarity. The SM15T200A-M3/57T is used where DC bias exists (e.g., power rails), while SM15T200CA suits AC-coupled or symmetrical signal lines like RS-485 or Ethernet.
What is the thermal resistance of SM15T200A-M3/57T, and how does it affect PCB layout?
The SM15T200A-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 operation below 150 °C junction temperature, PCB layout must replicate this pad area-or use internal copper planes-to avoid thermal derating. Smaller pads increase RθJA and reduce sustainable pulse repetition rate.
