Product details
Overview
SM15T200CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 200 V standoff voltage (VWM), and clamping voltage of 328 V at 4.6 A peak pulse current. It provides robust protection for automotive sensor signal lines against lightning-induced and inductive-switching transients.
For engineers reviewing the SM15T200CAHE3/9AT datasheet, SM15T200CAHE3/9AT pinout, SM15T200CAHE3/9AT application, or SM15T200CAHE3/9AT equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 200 V VWM, 328 V VC at IPPM, and SMC package thermal performance under high-impedance surge conditions.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical breakdown (VBR = 209–231 V) and clamping characteristics. Its low-inductance SMC package and glass-passivated junction enable fast response (<1 ns) to ESD and surge events while maintaining stable leakage (<1 μA at VWM) across -65 °C to +150 °C junction temperature range.
The device complies with AEC-Q101 stress testing for automotive applications and features MSL Level 1 moisture sensitivity. Thermal resistance is specified at RθJA = 75 °C/W (typical) and RθJL = 15 °C/W, supporting reliable operation on standard 8.0 mm × 8.0 mm copper pads without external heatsinking under nominal surge duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 200 V - Maximum continuous reverse operating voltage before conduction begins; defines upper limit of safe signal swing in protected line. |
| VBR (min/max) | 209 V / 231 V - Breakdown voltage range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 328 V at 4.6 A - Clamping voltage during 10/1000 μs surge; limits downstream IC stress to safe level during worst-case transient. |
| PPPM | 1500 W - Peak pulse power handling capability; supports protection against IEC 61000-4-5 Level 4 (4 kV) surges with system source impedance ≥50 Ω. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
SM15T200CAHE3/9AT uses a two-terminal SMC (DO-214AB) package with no polarity marking for bidirectional operation. Terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, qualified to JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on instantaneous polarity; no DC bias dependency; enables placement without orientation check. |
| Case (body) | Thermal and mechanical interface | Plastic-molded body meets UL 94 V-0 flammability; transfers heat to PCB copper pads; no electrical connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing; supports Tier-1 supply chain requirements. |
| 1500 W peak pulse power (10/1000 μs) | Withstands high-energy transients from inductive load switching and lightning coupling without degradation over rated lifetime. |
| Low clamping ratio (VC/VWM = 1.64) | Minimizes overvoltage stress on protected ICs compared to alternatives with higher ratios; improves system-level surge margin. |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free reflow assembly without moisture-related popcorning or delamination risk. |
| Glass-passivated junction | Provides stable leakage current (<1 μA at VWM) and long-term parameter stability under thermal cycling and humidity exposure. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding Ethernet PHY interfaces and PoE injectors from induced surges on outdoor cabling in building automation systems. IC Role / Device Role / Timing Role: Secondary protection stage following gas discharge tube (GDT), providing low-clamp precision after GDT arc extinguishes. Use Value: Achieves sub-330 V clamping at 4.6 A, ensuring compliance with IEC 61000-4-5 with <100 ns response time and <1 pF junction capacitance at zero bias. |
Use Scenario: Guarding microcontroller GPIOs and H-bridge gate drivers in smart washing machines against commutation spikes from universal motors and solenoid valves. IC Role / Device Role / Timing Role: Localized TVS mounted adjacent to motor driver IC to minimize loop inductance and maximize surge energy capture.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ200CA | Same 200 V VWM, but lower PPPM = 400 W; VC = 324 V at 1.2 A; not AEC-Q101 qualified. | Restricted to commercial-grade industrial or consumer applications with lower surge threat severity. | Select when cost sensitivity outweighs automotive qualification and 1500 W surge requirement. |
| ON Semiconductor 1.5SMC200CA | Identical 200 V VWM and 1500 W rating, but VC = 324 V at 4.6 A; AEC-Q101 qualified only in HE3 variant with different suffixing. | Requires verification of exact ordering code (e.g., 1.5SMC200CAHE3) to match automotive qualification status and tape/reel packaging. | Consider if existing BOM uses ON Semi's SMC footprint and logistics prefer same-supplier consolidation. |
Compared with SM15T200CAHE3/9AT, SMAJ200CA offers lower surge capacity and no automotive qualification, while 1.5SMC200CA matches core specs but requires careful suffix validation to ensure AEC-Q101 compliance and correct reel packaging (9AT).

FAQ
What does the "CA" suffix indicate in SM15T200CAHE3/9AT?
The "CA" suffix in SM15T200CAHE3/9AT denotes a bidirectional configuration, meaning the device clamps transients equally in both polarities without polarity dependence. This distinguishes it from unidirectional variants (e.g., SM15T200A) and enables placement without orientation constraints on differential or AC-coupled signal lines.
Is SM15T200CAHE3/9AT qualified for automotive applications?
Yes, SM15T200CAHE3/9AT is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's SM15T Series datasheet (Doc. #88380, Rev. 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing for use in automotive electronic control units.
What is the maximum clamping voltage for SM15T200CAHE3/9AT under surge conditions?
The maximum clamping voltage for SM15T200CAHE3/9AT is 328 V at 4.6 A peak pulse current with a 10/1000 μs waveform, as specified in the Electrical Characteristics table. This value represents the upper bound of voltage seen by protected circuitry during worst-case surge events within the device's rated power envelope.
Does SM15T200CAHE3/9AT require orientation during PCB placement?
No, SM15T200CAHE3/9AT does not require orientation during PCB placement because it is a bidirectional TVS with symmetrical terminals and no polarity marking. The SMC package has identical electrical behavior regardless of which terminal connects to line or return, simplifying automated assembly and reducing placement error risk.
What is the thermal resistance specification for SM15T200CAHE3/9AT?
SM15T200CAHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per terminal. These values assume standard SMC mounting and define safe power dissipation limits under continuous and pulsed operating conditions.
