Product details
Overview
1.5SMC200CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 274 V under 5.5 A peak pulse current, and maintains a 171 V stand-off voltage with ≤1.0 μA reverse leakage at 25 °C. It is used to protect MOSFETs, sensor interfaces, and automotive ECUs against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC200CA-E3/57T datasheet, 1.5SMC200CA-E3/57T pinout, 1.5SMC200CA-E3/57T application, or 1.5SMC200CA-E3/57T equivalent, this page provides verified electrical parameters, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal derating curves, and RoHS-compliant commercial-grade sourcing support at Aetrix Electronics.
Technical Context
The 1.5SMC200CA-E3/57T operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics due to its bidirectional CA construction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients on DC bus lines and CAN/FlexRay physical layers.
Thermal performance is defined by RθJA = 75 °C/W (on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, supporting operation up to TJ = +150 °C. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance, confirming suitability for lead-free reflow assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains single high-energy surges per IEC 61000-4-5 Level 4 without degradation |
| Stand-off Voltage (VWM) | 171 V - maximum continuous reverse voltage before significant leakage; sets operating margin below clamping |
| Breakdown Voltage (VBR) | 190–210 V at 1 mA - defines the onset of avalanche conduction; tight ±5% tolerance ensures predictable turn-on |
| Clamping Voltage (VC) | 274 V at 5.5 A IPPM - limits transient voltage seen by downstream ICs; determines required system overvoltage margin |
| Reverse Leakage (ID) | ≤1.0 μA at 171 V - negligible standby power loss and no measurable loading on protected signal/power rails |
| Operating Temperature | −65 °C to +150 °C - supports under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height for automated placement |
Pinout & Package
1.5SMC200CA-E3/57T uses the SMC (DO-214AB) package: a molded plastic case with two coplanar matte tin-plated leads, compliant with J-STD-002 solderability and JESD22-B102 thermal shock testing. Bidirectional construction means no polarity marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (symmetrical) | Either terminal serves as anode or cathode depending on instantaneous polarity of transient; no DC bias dependency |
| Terminal 2 | Anode/Cathode (symmetrical) | Electrically identical to Terminal 1; enables placement without orientation check during SMT assembly |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse rating | Enables compliance with IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs |
| Glass-passivated junction | Ensures stable avalanche characteristics over lifetime and prevents parametric drift under repeated surge stress |
| MSL Level 1 rating | Allows direct placement from dry pack without baking; eliminates moisture-related popcorning during reflow |
| RoHS-compliant & halogen-free option | E3 suffix confirms lead-free, bromine-free, antimony-free construction meeting EU Directive 2011/65/EU Annex II |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot during clamping-critical for protecting 200 V-rated MOSFETs and gate drivers |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 24 V battery-fed control modules against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input terminals to clamp positive and negative transients before DC/DC converters. Use Value: Withstands 1500 W surges while limiting voltage to 274 V-within safe operating area of 300 V input-rated buck controllers. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA loops) and digital sensor buses (CAN, LIN) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp installed at connector interface to shunt transients before signal conditioning circuitry. Use Value: ≤1.0 μA leakage preserves loop accuracy; symmetrical clamping protects against both polarities of induced noise on ungrounded sensor cables. |
| Telecom DC Power Feeds | Renewable Energy Inverter DC Links |
Use Scenario: Surge suppression on −48 V telecom rectifier outputs exposed to lightning-induced surges on long feeder lines. IC Role / Device Role / Timing Role: Primary-level TVS mounted directly at power entry point to absorb energy before upstream fusing and filtering. Use Value: 171 V VWM aligns with −48 V nominal systems using ±10% regulation; 274 V clamping avoids tripping downstream overvoltage protection. |
Use Scenario: Protecting IGBT gate drivers and DC-link capacitors in solar string inverters subjected to grid-switching transients. IC Role / Device Role / Timing Role: Parallel-mounted TVS across DC-link bus to clamp commutation spikes and fault-induced overvoltages. Use Value: 1500 W rating handles repetitive 10/1000 μs surges common in PV plant grid interconnection; 150 °C max junction temperature supports high-ambient rooftop mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower peak power (600 W), same VWM/VC, SMB (DO-214AA) package (smaller footprint, higher RθJA) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for load dump or long-line lightning protection | Select when board space is constrained and surge threat level is moderate (e.g., indoor consumer electronics). |
| 1.5KE200CA | Higher RθJA (100 °C/W), axial-leaded DO-15 package, same electrical specs but not SMT-compatible | Requires through-hole assembly; incompatible with automated SMT lines and high-density layouts | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs production efficiency. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CA-E3/57T uniquely balances 1500 W surge capability, SMC surface-mount compatibility, and commercial-grade RoHS compliance-making it the preferred choice for volume-manufactured automotive and industrial power systems requiring robust, automated, and standards-aligned protection.

FAQ
What is the clamping voltage of the 1.5SMC200CA-E3/57T under peak pulse conditions?
The 1.5SMC200CA-E3/57T has a maximum clamping voltage (VC) of 274 V at 5.5 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC200CA-E3/57T maintains this clamping performance consistently across its rated temperature range.
Is the 1.5SMC200CA-E3/57T suitable for automotive applications?
Yes-the 1.5SMC200CA-E3/57T is RoHS-compliant and qualified to AEC-Q101 when ordered with HE3 or HM3 suffixes. While the E3/57T variant is commercial-grade, its electrical specs (1500 W peak power, 150 °C TJmax, MSL Level 1) and construction (glass-passivated junction, matte tin leads) meet baseline requirements for under-hood and body-control module protection. For certified automotive use, specify 1.5SMC200CAHE3_A or equivalent.
Does the 1.5SMC200CA-E3/57T have polarity markings?
No-the 1.5SMC200CA-E3/57T is a bidirectional TVS diode (denoted by the "CA" suffix), meaning it functions identically in both directions and carries no cathode band or polarity marking. Both terminals are electrically interchangeable, simplifying PCB layout and eliminating orientation errors during automated placement. This symmetry is confirmed in Vishay's mechanical drawings and electrical characterization data.
What is the thermal resistance of the 1.5SMC200CA-E3/57T?
The 1.5SMC200CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal, and a junction-to-lead resistance (RθJL) of 15 °C/W. These values are critical for calculating safe power dissipation limits at elevated ambient temperatures and must be applied using Vishay's derating curves (Fig. 2) to ensure TJ remains ≤150 °C.
Can the 1.5SMC200CA-E3/57T replace a unidirectional TVS like 1.5SMC200A-E3/57T?
No-the 1.5SMC200CA-E3/57T is bidirectional and lacks polarity, whereas 1.5SMC200A-E3/57T is unidirectional with a defined cathode band. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC-coupled or floating lines (e.g., CAN bus), while unidirectional types are used where DC bias direction is fixed (e.g., +12 V rail to ground). Using 1.5SMC200CA-E3/57T in place of 1.5SMC200A-E3/57T may cause unintended conduction in DC-biased paths.
