Product details
Overview
1.5SMC200CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), clamping voltage of 328 V at 4.6 A, and operates across –65 °C to +150 °C. It is used to protect automotive sensor interfaces and industrial I/O circuits against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC200CAHM3_A/H datasheet, 1.5SMC200CAHM3_A/H pinout, 1.5SMC200CAHM3_A/H application, or 1.5SMC200CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with UL 497B for telecom and automotive surge protection standards.
Technical Context
This device is a glass-passivated, bidirectional TVS diode optimized for fast transient suppression without polarity sensitivity. Its low incremental surge resistance and sub-nanosecond response time enable effective clamping of ESD, EFT, and lightning surge waveforms per IEC 61000-4-2/4-4/4-5.
The 1.5SMC200CAHM3_A/H uses a planar junction structure mounted in an SMC (DO-214AB) package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It meets MSL Level 1 (260 °C peak reflow) and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade reliability.

| Telecom Line Card Surge Protection | Motor Drive Gate Driver Protection |
Use Scenario: Shielding Ethernet PHYs, PoE injectors, and DSL line interface units from lightning-induced common-mode surges on twisted-pair cables. IC Role / Device Role / Timing Role: First-stage protection device on differential pairs, placed before common-mode chokes and isolation transformers. Use Value: Limits common-mode surge voltage to <350 V within 1 ns, preventing dielectric breakdown in magnetics and PHY ESD structures. |
Use Scenario: Protecting high-side/low-side MOSFET gate drivers in BLDC inverters from Miller-induced voltage spikes during fast switching.

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 PPPM (600 W), same VWM/VBR range, SMB package (smaller thermal mass). | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive load-dump or industrial 4 kV testing. | Select when board space is constrained and surge threat level is moderate-requires derating for high-repetition transients. |
| 1.5KE200CA | Through-hole TO-218 package, identical electrical specs but higher RθJA (100 °C/W vs. 75 °C/W). | Not suitable for automated SMT assembly; requires manual soldering and larger PCB real estate. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |

FAQ
What is the clamping voltage of the 1.5SMC200CAHM3_A/H at its rated peak pulse current?
The 1.5SMC200CAHM3_A/H has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 4.6 A under the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events-critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is the 1.5SMC200CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC200CAHM3_A/H is AEC-Q101 qualified (denoted by the HM3 suffix) and halogen-free, making it suitable for automotive applications including engine control modules, ADAS sensors, and body electronics. It passes stress tests for high-temperature operating life, thermal cycling, and mechanical shock-meeting requirements for ASIL-B functional safety systems.
How does the bidirectional configuration of the 1.5SMC200CAHM3_A/H affect its use in circuit design?
The bidirectional configuration of the 1.5SMC200CAHM3_A/H eliminates polarity concerns during placement, enabling direct protection of AC-coupled lines, differential buses (e.g., RS-485, CAN), or floating inputs without external diode orientation checks. Unlike unidirectional TVS diodes, the 1.5SMC200CAHM3_A/H provides symmetrical clamping in both directions-simplifying layout and reducing risk of misassembly.
What is the thermal resistance of the 1.5SMC200CAHM3_A/H, and how does it impact PCB layout?
The 1.5SMC200CAHM3_A/H 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 repetitive surge conditions, PCB layout must provide adequate copper area and avoid thermal bottlenecks-especially in automotive under-hood environments where ambient temperatures exceed 105 °C.
Does the 1.5SMC200CAHM3_A/H meet UL safety certification requirements?
Yes, the 1.5SMC200CAHM3_A/H carries Underwriters Laboratories recognition under UL 497B (file E136766) for both unidirectional and bidirectional transient protectors. This certification validates its suitability for use in telecom, industrial, and consumer equipment requiring third-party safety compliance-reducing time-to-market for certified end products.
