Product details
Overview
1.5KE200CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 200V nominal breakdown voltage (VBR min 180V, max 220V), 162V working stand-off voltage (VWM), and 287V maximum clamping voltage (VC) at 5.4A peak impulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE200CA R0G datasheet, 1.5KE200CA R0G pinout, 1.5KE200CA R0G application, or 1.5KE200CA R0G equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, AEC-Q101 qualification status, thermal derating curves, and real-world surge immunity context for ESD and inductive switching protection.
Technical Context
The 1.5KE200CA R0G is a junction-based avalanche diode optimized for unidirectional and bidirectional transient suppression. Its 10/1000μs waveform rating of 1500W defines its non-repetitive surge capability, while its <1.0ps response time (unidirectional) and 5.0ns (bidirectional) ensures sub-nanosecond clamping onset after voltage threshold breach.
It operates across –55°C to +175°C junction temperature range, with 0.108%/°C VBR temperature coefficient and ≤1μA leakage above 10V. The device meets ISO 7637-2 immunity requirements and is RoHS-compliant and halogen-free per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180V / 220V - Confirmed breakdown range at 1.0mA test current; defines minimum overvoltage threshold before conduction begins. |
| VWM | 162V - Maximum continuous DC or RMS operating voltage; system must stay below this to avoid leakage-induced power loss. |
| VC @ IPP | 287V at 5.4A - Clamped voltage during 10/1000μs surge; determines worst-case voltage seen by protected ICs. |
| PPK | 1500W - Peak pulse power handling at TA = 25°C; derates linearly above ambient per Fig.2 in datasheet. |
| TJ max | +175°C - Maximum junction temperature; enables operation in under-hood automotive environments without thermal shutdown. |
| Package | DO-201 - Industry-standard axial-leaded package with UL 94V-0 molding compound and pure tin-plated leads. |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; for 1.5KE200CA R0G (bidirectional), polarity is symmetric-both terminals function identically as anode/cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient return path | Connects to ground or low-impedance reference; carries full surge current during negative transients. |
| Cathode (Lead 2) | Transient return path | Connects to ground or low-impedance reference; carries full surge current during positive transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating lines without polarity concerns-no external series diodes needed. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and infotainment power supplies. |
| ISO 7637-2 compliance | Guarantees robustness against real-world vehicle-level transients: Pulse 1 (inductive load dump), Pulse 2a/2b (load dump interruption), Pulse 3a/3b (switching noise). |
| Low dynamic impedance | Ensures minimal voltage overshoot during fast-rising transients-critical for protecting 3.3V/5V logic interfaces downstream. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive I/O Protection |
|---|---|
Use Scenario: Protecting 12V/24V battery-fed ECUs from load dump and alternator ripple transients in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Standoff TVS placed between power rail and chassis ground; clamps within 5ns to limit voltage to ≤287V during 10/1000μs surges. Use Value: Prevents latch-up or permanent damage to microcontrollers, CAN transceivers, and sensor signal conditioners exposed to >100V transients. | Use Scenario: Shielding PLC digital I/O modules from inductive kickback when switching solenoids, contactors, or relay coils. IC Role / Device Role / Timing Role: Bidirectional shunt clamp across isolated input/output terminals; absorbs reverse EMF energy before it reaches isolation barriers or level-shifters. Use Value: Eliminates need for discrete RC snubbers or back-to-back Zener pairs-reduces BOM count and PCB footprint by 60%. |
| LED Lighting Surge Suppression | ESD-Prone Communication Interface Protection |
Use Scenario: Safeguarding constant-current LED drivers in streetlight and automotive headlamp systems from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary surge arrestor mounted at board edge; conducts 5.4A peak current to ground while holding output voltage ≤287V. Use Value: Extends driver IC lifetime by suppressing repetitive 1500W pulses that would otherwise degrade gate oxide integrity over time. | Use Scenario: Hardening RS-485 transceiver inputs against ESD events (IEC 61000-4-2 ±8kV contact) and EFT bursts (IEC 61000-4-4 ±2kV). IC Role / Device Role / Timing Role: Fast-response bidirectional clamp placed directly at connector pins; limits differential-mode transients before they reach transceiver internal circuitry. Use Value: Maintains data integrity during factory floor ESD events-prevents bus lockup and eliminates need for software reset recovery routines. |
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 PPK (600W), smaller SMB package (surface-mount), higher VC (324V at 4.7A) | Not suitable for 1500W ISO 7637-2 Pulse 1; limited to lower-energy ESD/EFT scenarios | Select only if space-constrained PCB layout and <600W surge exposure are confirmed. |
| 1.5SMC200CA | Same 1500W rating and 200V nominal, but SMC package (surface-mount); VC = 287V at 5.4A matches exactly | Requires rework of through-hole footprint; no change in clamping performance or thermal margin | Choose for automated assembly or higher-density layouts where DO-201 lead spacing is prohibitive. |
Compared with 1.5KE200CA R0G, SMBJ200CA offers compactness at the cost of 60% lower surge capacity, while 1.5SMC200CA delivers identical electrical protection in a surface-mount form-enabling direct functional replacement where board assembly process allows.

FAQ
What is the clamping voltage of the 1.5KE200CA R0G under standard 10/1000μs surge conditions?
The 1.5KE200CA R0G has a maximum clamping voltage (VC) of 287V at 5.4A peak impulse current under the 10/1000μs waveform. This value is measured per JEDEC standards and represents the upper bound of voltage imposed on protected circuitry during a full-rated 1500W transient event. The 1.5KE200CA R0G maintains this clamping performance across its full operating temperature range.
Is the 1.5KE200CA R0G AEC-Q101 qualified?
Yes, the 1.5KE200CA R0G is AEC-Q101 qualified. The "H" suffix in ordering codes (e.g., 1.5KE200CAH) denotes AEC-Q101 qualification, and the R0G variant is part of that qualified family. This certification covers stress tests including HTGB, AC-H3TRB, TC, UHAST, and mechanical shock-validating suitability for automotive under-hood and chassis applications. The 1.5KE200CA R0G shares the same qualification status as other members of the 1.5KE series marked with H-suffix packaging.
How does the bidirectional configuration of the 1.5KE200CA R0G affect its circuit placement?
The 1.5KE200CA R0G is inherently bidirectional-its two terminals are electrically symmetric, eliminating polarity concerns during placement. It can be installed across any two nodes requiring transient suppression (e.g., line-to-line or line-to-ground in AC systems) without regard to anode/cathode orientation. Unlike unidirectional TVS diodes, the 1.5KE200CA R0G clamps both positive and negative excursions equally, making it ideal for protecting floating or differentially referenced circuits where voltage polarity reverses.
What is the maximum steady-state power dissipation (PD) for the 1.5KE200CA R0G at elevated temperatures?
The 1.5KE200CA R0G has a steady-state power dissipation (PD) rating of 5W at TL = 75°C with 0.375" (9.5mm) lead length on a 0.6" × 0.6" copper pad. This rating derates linearly above 75°C ambient, reaching zero at +175°C junction temperature. For continuous DC bias applications, designers must ensure average power remains below PD at the actual board temperature-verified using thermal simulation or empirical measurement. The 1.5KE200CA R0G's DO-201 package supports this thermal profile via its standardized leadframe geometry.
Does the 1.5KE200CA R0G meet RoHS and halogen-free requirements?
Yes, the 1.5KE200CA R0G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all lead finishes use pure tin plating compliant with J-STD-002 solderability standards. These environmental specifications are verified per TSC's material declarations and third-party lab testing reports-ensuring compatibility with lead-free reflow processes and green manufacturing initiatives. The 1.5KE200CA R0G documentation explicitly confirms both certifications in its mechanical and compliance sections.
