Product details
Overview
1.5SMC200A-M3/9AT 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 maximum clamping voltage 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 controllers, and telecom line interfaces.
For engineers reviewing the 1.5SMC200A-M3/9AT datasheet, 1.5SMC200A-M3/9AT pinout, 1.5SMC200A-M3/9AT application, or 1.5SMC200A-M3/9AT equivalent, key selection criteria include clamping performance under 10/1000 µs transients, thermal resistance (RθJA = 75 °C/W), unidirectional polarity marking, and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (190–210 V at 1 mA), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 µA at 171 V) and fast response time (<1.0 ns).
Designed for SMC (DO-214AB) surface-mount assembly, it supports automated placement and meets J-STD-020 MSL Level 1 (260 °C reflow peak). The cathode band identifies polarity, and its 150 °C max junction temperature enables operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping. |
| VBR (min/max) | 190 V / 210 V at 1 mA - Breakdown voltage range confirming reliable avalanche initiation across production lot. |
| VC @ IPPM | 274 V at 5.5 A - Clamping voltage during 10/1000 µs surge; determines maximum stress imposed on protected IC or MOSFET. |
| PPPM | 1500 W - Peak pulse power handling capability; validates robustness against lightning-induced or inductive-switching transients. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained power dissipation. |
| IFSM | 200 A - Non-repetitive forward surge current rating; supports single-event overvoltage events like load dump. |
| TJ max | +150 °C - Maximum junction temperature; enables use in high-temperature automotive and industrial enclosures. |
Pinout & Package
Package: SMC (DO-214AB) - surface-mount plastic case with matte tin-plated leads, UL 94 V-0 rated molding compound, and 0.305" × 0.320" footprint optimized for thermal dissipation on 8.0 mm × 8.0 mm copper pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane; completes shunt path for transient energy diversion. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables protection against severe lightning surges (IEC 61000-4-5 Level 4) without derating in standard PCB layouts. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping precision for sensitive 200 V-rated components. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage current across temperature and humidity stress conditions. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and environmental compliance for global automotive OEM programs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead in high-volume SMT lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-M3/8A | Lower peak power (600 W), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for 1500 W lightning strikes. | Select only where space constraints prohibit SMC and surge energy is confirmed ≤600 W. |
| 1.5KE200A | Through-hole DO-201 package; identical VWM/VC specs but no M3 halogen-free compliance or MSL Level 1 rating. | Not suitable for automated SMT lines; requires wave soldering and lacks automotive reflow compatibility. | Choose only for legacy through-hole designs or prototyping where RoHS/halogen-free requirements are waived. |
Compared with SMBJ200A-M3/8A and 1.5KE200A, the 1.5SMC200A-M3/9AT delivers superior surge robustness in an MSL Level 1–qualified, halogen-free SMT package - making it the preferred choice for volume automotive and industrial designs requiring 1500 W clamping and zero reflow risk.

FAQ
What is the maximum clamping voltage of the 1.5SMC200A-M3/9AT under a 10/1000 µs surge?
The 1.5SMC200A-M3/9AT exhibits a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 5.5 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay's 88303 datasheet and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC200A-M3/9AT suitable for automotive applications?
Yes - the 1.5SMC200A-M3/9AT carries AEC-Q101 qualification (as indicated by the "A" suffix in the 1.5SMC200A family and M3 halogen-free compliance), supports 150 °C junction temperature, and meets MSL Level 1 reflow requirements. It is explicitly recommended for automotive power supply protection, including load dump and ISO 7637-2 compliance scenarios.
How does the M3 suffix affect the 1.5SMC200A-M3/9AT's compliance profile?
The M3 suffix on the 1.5SMC200A-M3/9AT denotes halogen-free, RoHS-compliant construction per JEDEC standards, with whisker-resistant matte tin plating and JESD201 Class 2 qualification. Unlike E3-suffix variants, M3 ensures full compliance with automotive OEM material declarations and eliminates brominated flame retardants in the molding compound.
What is the thermal resistance of the 1.5SMC200A-M3/9AT, and how does it impact layout?
The 1.5SMC200A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under sustained power dissipation, PCB layout must allocate adequate copper area and avoid thermal isolation - especially critical in enclosed automotive modules.
Does the 1.5SMC200A-M3/9AT have bidirectional capability?
No - the 1.5SMC200A-M3/9AT is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional operation, Vishay offers the 1.5SMC200CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities and no polarity marking.
