Product details
Overview
1.5SMC200AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for high-energy surge 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 (VC) at 5.5 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supplies, industrial motor drives, and telecom DC input stages.
For engineers reviewing the 1.5SMC200AHE3/9AT datasheet, 1.5SMC200AHE3/9AT pinout, 1.5SMC200AHE3/9AT application, or 1.5SMC200AHE3/9AT equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, SMC (DO-214AB) package thermal resistance, and unidirectional polarity marking for correct PCB orientation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to ESD and lightning-induced transients. Its unidirectional configuration provides forward conduction capability up to 200 A IFSM (8.3 ms half-sine), while maintaining low incremental surge resistance for stable clamping behavior across repetitive surges.
The 1.5SMC200AHE3/9AT is rated for TJ = -65 °C to +150 °C operation, meets MSL Level 1 per J-STD-020, and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its AEC-Q101 qualification confirms suitability for automotive power electronics where reliability under thermal cycling and vibration is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin in protected circuits. |
| VBR (Breakdown Voltage) | 190–210 V at IT = 1 mA - Voltage at which avalanche conduction begins; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 274 V at IPPM = 5.5 A (10/1000 μs) - Peak voltage seen by downstream circuitry during surge; determines protection margin for 24 V or 48 V systems. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity under standardized 10/1000 μs surge; supports IEC 61000-4-5 Level 4 compliance when properly mounted. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm copper pads; informs derating above TA = 25 °C per Fig. 2. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments with adequate board layout. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing per AEC specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/57T | Same VWM/VBR/VC specs but lower PPPM (400 W), SMA package (DO-214AC), RθJA = 110 °C/W. | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy consumer interfaces. | Select only if space-constrained layouts prohibit SMC footprint and surge energy is <400 W. |
| 1.5KE200A | Through-hole TO-204AA (DO-41), same electrical specs but higher RθJA (100 °C/W), no AEC-Q101 option. | Requires wave soldering; unsuitable for automated SMT lines or automotive under-hood use. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ200A-E3/57T and 1.5KE200A, the 1.5SMC200AHE3/9AT delivers superior surge energy handling (1500 W vs. 400 W or 1500 W with inferior thermal performance), AEC-Q101 qualification, and SMT process compatibility - making it the preferred choice for production automotive and industrial power systems.

FAQ
What is the clamping voltage of the 1.5SMC200AHE3/9AT at its rated peak pulse current?
The 1.5SMC200AHE3/9AT has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 5.5 A using the 10/1000 μs waveform. This value is measured under standard test conditions (TA = 25 °C, mounted on 8 mm × 8 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC200AHE3/9AT qualified for automotive applications?
Yes, the 1.5SMC200AHE3/9AT is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its use in automotive powertrain, body control, and infotainment systems.
What does the "9AT" suffix indicate in 1.5SMC200AHE3/9AT?
The "9AT" suffix denotes packaging: 13-inch diameter plastic tape and reel, with a standard quantity of 3500 units per reel. This format supports high-volume automated SMT placement and is compatible with industry-standard pick-and-place feeders used in electronics manufacturing.
How does the thermal resistance of the 1.5SMC200AHE3/9AT affect its power derating?
The 1.5SMC200AHE3/9AT has a typical RθJA of 75 °C/W on standard 8 mm × 8 mm copper pads. As ambient temperature rises above 25 °C, its peak pulse power must be linearly derated per Figure 2 in the datasheet - e.g., at TA = 75 °C, usable PPPM drops to ~750 W to maintain TJ ≤ 150 °C.
Can the 1.5SMC200AHE3/9AT be used in bidirectional configurations?
No, the 1.5SMC200AHE3/9AT is unidirectional only, as indicated by the "A" suffix (not "CA"). For bidirectional operation, Vishay offers the 1.5SMC200CA variant, which provides symmetrical clamping in both polarities and is marked without polarity band.
