Product details
Overview
1.5SMC200A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 200 V standoff voltage (VWM), 274 V clamping voltage (VC) at 5.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - ideal for safeguarding MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC200A-E3/9AT datasheet, 1.5SMC200A-E3/9AT pinout, 1.5SMC200A-E3/9AT application, or 1.5SMC200A-E3/9AT equivalent, key selection criteria include its unidirectional polarity, DO-214AB (SMC) package, 171 V minimum breakdown voltage (VBR), 1.0 mA test current, and compliance with AEC-Q101 qualification when ordered with HE3/HM3 suffixes - critical for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 200 V reverse standoff voltage (VWM) and rapidly transitions to low-impedance conduction above its 171–189 V breakdown range (VBR), limiting transient voltages to ≤274 V at rated IPPM. Its glass-passivated junction ensures stable performance under repetitive surge stress.
Thermal design relies on its 75 °C/W junction-to-ambient thermal resistance (RθJA) and 15 °C/W junction-to-leads (RθJL), requiring PCB copper pad areas of 8.0 mm × 8.0 mm per terminal for full 1500 W pulse rating. It meets MSL Level 1 per J-STD-020 with 260 °C peak reflow profile compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protection of 24 V battery-fed control modules against load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients up to 120 V peak.

Use Scenario: Secondary-side overvoltage suppression in switched-mode power supplies for refrigerators and washing machines. IC Role / Device Role / Timing Role: Clamp across output capacitor terminals to prevent overvoltage failure during feedback loop faults. Use Value: 200 V VWM matches typical 19 V–24 V DC outputs; 274 V VC ensures safe margin below 400 V-rated electrolytic capacitor ratings. |
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 200 V VWM, but SMB package (DO-214AA); 600 W PPPM rating vs. 1500 W | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for load dump or motor drive scenarios | Select only if board space is constrained and surge threat level is ≤600 W - verify thermal derating on smaller pads |
| 1.5KE200A | Through-hole TO-204AE (DO-41); identical 200 V VWM and 274 V VC, but 1500 W rating requires lead length ≤0.375" | Not suitable for automated SMT assembly; incompatible with high-density PCB layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ200A and 1.5KE200A, the 1.5SMC200A-E3/9AT delivers SMT-compatible 1500 W surge immunity in a compact DO-214AB footprint - uniquely balancing high-power clamping, RoHS compliance, and automated manufacturability for automotive and industrial production.

FAQ
What is the clamping voltage of the 1.5SMC200A-E3/9AT under a 10/1000 μs surge?
The 1.5SMC200A-E3/9AT has a maximum clamping voltage (VC) of 274 V at 5.5 A peak pulse current 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 1.5SMC200A-E3/9AT maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC200A-E3/9AT RoHS-compliant and halogen-free?
Yes, the 1.5SMC200A-E3/9AT carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications. It is not halogen-free - for halogen-free and RoHS-compliant versions, the "M3" suffix (e.g., 1.5SMC200A-M3/9AT) must be selected. Both E3 and M3 variants meet JESD 201 Class 2 whisker resistance requirements.
Does the 1.5SMC200A-E3/9AT have AEC-Q101 qualification?
No, the 1.5SMC200A-E3/9AT itself is not AEC-Q101 qualified. However, Vishay offers AEC-Q101-qualified versions under the HE3 (RoHS-compliant, AEC-Q101) and HM3 (halogen-free, RoHS-compliant, AEC-Q101) suffixes - for example, 1.5SMC200AHE3_A/I. The 1.5SMC200A-E3/9AT is intended for commercial and industrial applications where automotive qualification is not required.
What is the thermal resistance of the 1.5SMC200A-E3/9AT, and how does it affect layout?
The 1.5SMC200A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W. To achieve full 1500 W pulse rating, the device must be mounted on minimum 8.0 mm × 8.0 mm copper pads per terminal. Reducing pad area increases RθJA, requiring derating of peak power - refer to Figure 2 in the Vishay 88303 datasheet for precise derating curves.
How does the 1.5SMC200A-E3/9AT differ from bidirectional variants like 1.5SMC200CA?
The 1.5SMC200A-E3/9AT is unidirectional, with polarity marked by a cathode band and intended for DC line protection where surge direction is known (e.g., positive rail to ground). In contrast, 1.5SMC200CA is bidirectional, symmetrical in both directions, and used in AC-coupled or differential signal paths. Their VWM, VBR, and VC values differ: 1.5SMC200CA has 171 V VWM (vs. 200 V), 190–210 V VBR, and 274 V VC - making them non-interchangeable without circuit redesign.
