Product details
Overview
1.5SMC200AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 µs). It delivers 5.5 A peak pulse current (IPPM) with 274 V maximum clamping voltage (VC), and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the 1.5SMC200AHE3_A/I datasheet, 1.5SMC200AHE3_A/I pinout, 1.5SMC200AHE3_A/I application, or 1.5SMC200AHE3_A/I equivalent, this part serves as a high-energy, low-clamping TVS for protecting sensitive power rails and signal lines against lightning surges, inductive switching transients, and ESD events in harsh environments.
Technical Context
The 1.5SMC200AHE3_A/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by the 10/1000 µs double-exponential waveform standard per REA, with thermal derating above 25 °C per Fig. 2.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C) and supports automated placement. Polarity is marked by a cathode band; no marking applies to bidirectional variants - but this part is unidirectional.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA test current - Voltage at which device enters controlled avalanche; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 274 V at 5.5 A IPPM - Peak voltage seen across protected circuit during 1500 W transient; critical for IC/MOSFET overvoltage margin. |
| PPPM (Peak Pulse Power) | 1500 W (10/1000 µs) - Energy-handling capability under standardized surge waveform; enables robust protection against lightning-induced spikes. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Ultra-low leakage preserves system efficiency and avoids false triggering in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial ambient conditions. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-supplied ECUs, body control modules, and lighting drivers from load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground, clamping transients before they reach DC-DC converters and microcontrollers. Use Value: Withstands 1500 W pulses while limiting clamped voltage to 274 V - well below typical 300 V MOSFET breakdown, preventing catastrophic failure. |
Use Scenario: Safeguarding analog front-ends and I²C/SPI lines of pressure, temperature, and position sensors in factory automation equipment. IC Role / Device Role / Timing Role: Low-leakage (1 µA) TVS mounted directly at connector entry points to shunt ESD and cable discharge events. Use Value: Sub-1 ns response and 274 V clamping ensure sensor ICs remain undamaged during 8 kV contact ESD per IEC 61000-4-2. |
| Telecom DC Power Input Protection | Renewable Energy Inverter DC Link Protection |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges entering central office or remote radio units. IC Role / Device Role / Timing Role: Primary-level TVS on input stage, coordinated with upstream fuses and secondary-stage polymer PTCs. Use Value: 171 V VWM provides 20 % margin above nominal -48 V (derated for ripple), while 274 V VC prevents latch-up in downstream PMICs. |
Use Scenario: Shielding high-voltage DC link capacitors and gate drivers in solar string inverters from grid-switching transients and fault currents. IC Role / Device Role / Timing Role: Parallel-mounted TVS on 200–400 V DC bus, selected for stable VBR tolerance (±5 %) and low thermal resistance (RθJL = 15 °C/W). Use Value: AEC-Q101 qualification and 150 °C TJ max ensure reliability in sealed, thermally constrained inverter enclosures exposed to desert or rooftop ambient extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/57T | Same 200 V VWM, but lower PPPM (400 W), smaller SMA package (DO-214AC), non-AEC-Q101. | Limited to low-energy consumer or non-automotive industrial use; unsuitable for load dump or sustained surge duty cycles. | Select only if space-constrained and transient energy is <400 W; verify layout thermal relief for 6.5 W PD. |
| 1.5KE200A | Through-hole TO-204AE (DO-41), same VWM/VC specs, but higher RθJA (100 °C/W vs. 75 °C/W), no AEC-Q101. | Requires PCB real estate for axial leads; not compatible with SMT-only lines; lacks automotive qualification evidence. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is irrelevant. |
Compared with SMAJ200A-E3/57T and 1.5KE200A, the 1.5SMC200AHE3_A/I offers superior surge handling (1500 W vs. 400 W or 1500 W with inferior thermal performance), AEC-Q101 validation, and optimized SMT manufacturability - making it the preferred choice for production automotive and high-reliability industrial systems.

FAQ
What is the clamping voltage of the 1.5SMC200AHE3_A/I at its rated peak pulse current?
The 1.5SMC200AHE3_A/I has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 5.5 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with devices mounted on 8.0 mm × 8.0 mm copper pads per terminal, as specified in Vishay Document 88303.
Is the 1.5SMC200AHE3_A/I suitable for automotive applications?
Yes, the 1.5SMC200AHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD - making it approved for use in engine control units, ADAS modules, and other automotive electronic systems.
What does the "_A/I" suffix mean in 1.5SMC200AHE3_A/I?
The "_A" denotes the voltage variant (200 V VWM) and AEC-Q101 qualification level; "/I" specifies packaging in 13-inch diameter plastic tape and reel with a 3500-unit quantity per reel. This ordering code aligns with Vishay's standard format for automotive-grade SMC TVS diodes, ensuring traceability and process compatibility.
How does the thermal resistance of the 1.5SMC200AHE3_A/I affect its power dissipation capability?
The 1.5SMC200AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W. At 25 °C ambient, its steady-state power dissipation (PD) is rated at 6.5 W; however, derating is required above 25 °C per Figure 2 in the datasheet - e.g., ~4.5 W at 70 °C ambient - to maintain TJ ≤ 150 °C.
Can the 1.5SMC200AHE3_A/I be used in bidirectional configurations?
No, the 1.5SMC200AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional operation requires the "CA" variant (e.g., 1.5SMC200CA), which exhibits symmetrical clamping in both polarities. Using the 1.5SMC200AHE3_A/I in reverse-biased signal paths may result in unintended conduction or failure.
