Product details
Overview
1.5SMC200A-E3/57T 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 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), 274 V maximum clamping voltage at 5.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive power supplies and industrial motor drive interfaces.
For engineers reviewing the 1.5SMC200A-E3/57T datasheet, 1.5SMC200A-E3/57T pinout, 1.5SMC200A-E3/57T application, or 1.5SMC200A-E3/57T equivalent, this page delivers verified electrical parameters, SMC (DO-214AB) package details, clamping performance under surge conditions, and direct alternatives for ESD and lightning transient suppression in high-reliability DC systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche response. Its 1500 W peak pulse rating is specified under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and thermal resistance is characterized at RθJA = 75 °C/W on recommended 8.0 mm × 8.0 mm copper pads.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of transients induced by inductive switching or lightning surges. It meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and is RoHS-compliant (E3 suffix) with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC operating margin. |
| VBR (Breakdown) | 190–210 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 274 V at IPPM = 5.5 A - Measured peak voltage across device during 10/1000 μs surge; determines protected circuit stress level. |
| PPPM | 1500 W - Peak pulse power handling under standard waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | 1.0 μA max at VWM - Ultra-low reverse leakage preserves system efficiency and minimizes standby power loss. |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated placement. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; cathode indicated by black band on one end; terminals are anode and cathode (unidirectional polarity).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Enables standard diode conduction path during fault; must be tied to ground or return rail in clamp-to-rail configuration. |
| Cathode | Current exit point in forward bias; marked with black band; connected to protected line | Serves as the high-side connection point for transient clamping; defines polarity-sensitive placement on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) without derating on standard PCB layout. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak, eliminating moisture sensitivity concerns. |
| AEC-Q101 qualification option | HE3/HM3 variants available for automotive applications; this E3/57T variant is commercial-grade but built on same qualified process. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during surge, reducing stress on downstream MOSFETs and controllers. |
Applications
| Automotive Power Input Protection | Industrial Motor Drive DC Bus |

IC Role / Device Role: First-stage clamping device after MOV, providing precise, low-leakage secondary protection. Use Value: 1.0 μA max leakage at 200 V avoids unnecessary power loss while maintaining tight clamping accuracy. |
Use Scenario: Secondary-side 12 V/24 V output rail in washing machine or HVAC control boards facing relay coil kickback. IC Role / Device Role: Localized TVS across solenoid driver outputs to suppress inductive turn-off spikes. Use Value: Fast <1 ns response prevents latch-up in logic-level MOSFETs and protects isolated feedback optocouplers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VWM (200 V) and VC (274 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA) | Lower surge capacity limits use to non-automotive, low-energy circuits; unsuitable for ISO 7637-2 Pulse 5a compliance. | Select when board space is constrained and surge threat level is ≤ 1 kV IEC 61000-4-5. |
| 1.5KE200A | Through-hole TO-204AA (DO-41); identical VWM/VBR/VC specs but higher RθJA (100 °C/W) and no MSL rating | Requires wave soldering; not suitable for mixed-technology SMT-only lines or high-volume automated assembly. | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ200A and 1.5KE200A, the 1.5SMC200A-E3/57T delivers full 1500 W surge handling in a surface-mount package with MSL Level 1 and RoHS compliance - making it the preferred choice for production-grade automotive and industrial SMT power rails requiring validated surge immunity and assembly scalability.

FAQ
What is the maximum clamping voltage of the 1.5SMC200A-E3/57T under standard surge conditions?
The 1.5SMC200A-E3/57T has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 5.5 A using the industry-standard 10/1000 μs waveform. This value is measured at TJ = 25 °C on 8.0 mm × 8.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the 1.5SMC200A-E3/57T suitable for automotive applications?
The 1.5SMC200A-E3/57T is RoHS-compliant and manufactured using the same platform as AEC-Q101-qualified variants (e.g., 1.5SMC200AHE3_A), but this specific E3/57T ordering code is commercial-grade. For production automotive use, specify the HE3 or HM3 suffix; however, the 1.5SMC200A-E3/57T remains widely used in automotive prototyping and non-safety-critical subsystems due to identical electrical specs and robust construction.
What does the "-E3/57T" suffix indicate in 1.5SMC200A-E3/57T?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch diameter plastic tape and reel containing 850 units. This format ensures compatibility with high-speed pick-and-place equipment and supports JIT manufacturing workflows without manual handling or repackaging.
How does the thermal performance of the 1.5SMC200A-E3/57T affect PCB layout?
The 1.5SMC200A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under worst-case 6.5 W steady-state dissipation, designers must ensure adequate copper area, avoid thermal bottlenecks, and consider airflow or heatsinking for high-duty-cycle surge environments.
Can the 1.5SMC200A-E3/57T replace a 1.5KE200A in an existing design?
The 1.5SMC200A-E3/57T matches the 1.5KE200A's key electrical parameters (VWM, VBR, VC, PPPM), but it uses an SMC (DO-214AB) surface-mount package versus the 1.5KE200A's through-hole DO-41. Direct replacement requires PCB redesign to accommodate the SMC footprint and reflow profile; it is not a drop-in mechanical substitute, though electrical behavior is functionally equivalent.
