Product details
Overview
1.5SMC200CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a 200V breakdown voltage range (190–210V), 171V working stand-off voltage, and 274V maximum clamping voltage at 5.7A peak impulse current. It features AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and is used for ESD and surge protection in automotive power line interfaces.
For engineers reviewing the 1.5SMC200CAH datasheet, 1.5SMC200CAH pinout, 1.5SMC200CAH application, or 1.5SMC200CAH equivalent, key selection criteria include clamping performance under 10/1000μs surge, bidirectional symmetry, thermal resistance (RθJC = 15°C/W), and moisture sensitivity level (MSL 1).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector in bidirectional configurations, responding to transients in both polarities with sub-1ps response time. Its glass-passivated junction ensures stable VBR hysteresis and low leakage (<1μA @ 171V), while the DO-214AB (SMC) package supports high-power dissipation (1500W peak, 6.5W steady-state) and automotive-grade reliability.
The device meets stringent automotive EMC requirements including ISO 7637-2 Pulse 1 (inductive load dump suppression), Pulse 2b (battery disconnect), and Pulse 3a/3b (capacitive coupling transients). Thermal design leverages RθJA = 50°C/W and RθJC = 15°C/W for PCB-level heatsinking in engine control units and body electronics.

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 | 600W peak power rating (vs. 1500W); same DO-214AA package; VC = 324V @ 1.9A | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); not suitable for ISO 7637-2 Pulse 5a load dump | Select when board space is constrained and surge energy is ≤600W - requires verification of clamping margin with downstream ICs |
| 1.5KE200CA | Through-hole TO-204AA (DO-41) package; same 1500W rating; VC = 274V @ 5.5A; slower thermal response | Not compatible with SMT assembly; higher RθJA (~65°C/W) limits high-duty-cycle use in compact enclosures | Choose only for legacy through-hole designs or where manual rework is preferred; avoid in new automotive SMT layouts |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CAH delivers superior surge handling in surface-mount form - its 1500W rating and 15°C/W RθJC enable direct PCB heatsinking for sustained transient immunity in engine control and industrial automation.

FAQ
What is the clamping voltage of the 1.5SMC200CAH under standard 10/1000μs surge conditions?
The 1.5SMC200CAH has a maximum clamping voltage (VC) of 274 V at 5.7 A peak impulse current (IPPM) under the standardized 10/1000μs double-exponential surge waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case transients such as ISO 7637-2 Pulse 5a load dump events. The 1.5SMC200CAH maintains this clamping performance across its full operating temperature range (−55°C to +150°C).
Is the 1.5SMC200CAH suitable for bidirectional automotive data lines like CAN FD?
No - the 1.5SMC200CAH is rated for 171 V working stand-off voltage and 274 V clamping, making it unsuitable for direct placement on low-voltage differential buses such as CAN FD (nominal ±1–3 V). It is designed for high-voltage power rail protection (e.g., 24V/48V battery feeds). For CAN FD, lower-voltage TVS devices like the SMAJ12CA (12 V VWM) are appropriate. The 1.5SMC200CAH protects the power domain that supplies the CAN transceiver, not the signal lines themselves.
Does the 1.5SMC200CAH require a heatsink for 1500W surge handling?
No external heatsink is required for single-event 1500W surge handling because the 1.5SMC200CAH's energy absorption occurs within milliseconds and relies on junction thermal mass, not steady-state conduction. However, PCB layout must provide ≥1 cm² of 2-oz copper connected to both terminals to achieve the specified RθJA = 50°C/W. Repeated surges demand thermal derating per Fig.2 in the datasheet - the 1.5SMC200CAH's RθJC = 15°C/W enables efficient heat transfer to internal ground planes.
How does the 1.5SMC200CAH differ from the unidirectional 1.5SMC200H variant?
The 1.5SMC200CAH is bidirectional with symmetrical VBR (190–210 V) and identical clamping in both polarities, while the 1.5SMC200H is unidirectional and conducts only in reverse bias - its forward voltage is 5.0 V at 50 A. The CAH suffix indicates center-tap anode/cathode symmetry and absence of polarity marking. This makes the 1.5SMC200CAH ideal for AC-coupled or floating DC systems (e.g., telecom -48V feeds), whereas the 1.5SMC200H suits grounded positive-rail applications where forward conduction must be blocked.
What is the moisture sensitivity level (MSL) and reflow profile compatibility of the 1.5SMC200CAH?
The 1.5SMC200CAH is rated MSL 1 per J-STD-020, meaning it has unlimited floor life and may be placed directly into standard lead-free reflow profiles (e.g., JEDEC J-STD-020D peak = 260°C, 60–90 seconds above 217°C) without pre-baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the UL 94V-0 molding compound withstands multiple reflow cycles. This eliminates handling complexity in high-volume SMT lines - a key advantage of the 1.5SMC200CAH over MSL 3+ alternatives.
