Product details
Overview
1.5KE200C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 200V nominal breakdown voltage (VBR = 180–220V @ IT = 1mA), 162V working stand-off voltage (VWM), and 287V maximum clamping voltage (VC) at 5.4A peak pulse current. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE200C datasheet, 1.5KE200C pinout, 1.5KE200C application, or 1.5KE200C equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity, clamping performance under 10/1000μs surge, junction temperature limits (−55°C to +175°C), and AEC-Q101-qualified alternatives for automotive-grade ESD and load-dump protection.
Technical Context
The 1.5KE200C operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its VBR threshold (180–220V), enabling precise overvoltage clamping without forward conduction during normal operation. Its low dynamic impedance ensures rapid energy diversion during transients, while the 10/1000μs waveform rating confirms compliance with ISO 7637-2 for automotive load-dump immunity.
Designed for surface-mount or through-hole PCB mounting on copper pads (0.6" × 0.6"), it sustains 1500W non-repetitive peak pulse power at TA = 25°C and derates linearly above that ambient - delivering 5W steady-state dissipation at TL = 75°C. The cathode band marking defines polarity, critical for correct orientation in DC-biased protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

|---|---|
Use Scenario: 12V/24V battery-fed ECUs exposed to load-dump transients up to 120V per ISO 7637-2 Pulse 5a. IC Role / Device Role: Unidirectional TVS placed between power rail and ground to clamp surges before they reach LDOs or microcontrollers. Use Value: Limits voltage to ≤287V during 10/1000μs 5.4A surge, preserving 3.3V/5V logic supply integrity and preventing latch-up. | Use Scenario: Digital input modules receiving 24VDC signals from field sensors in factory automation. IC Role / Device Role: Front-end protection element on each channel to absorb EFT bursts (IEC 61000-4-4) and cable discharge events. Use Value: Blocks >1000V transients while maintaining <1µA leakage at 162V, ensuring signal fidelity and long-term reliability. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
Use Scenario: Constant-current LED drivers powered from unregulated 20–36V supplies subject to switching noise and inductive kickback. IC Role / Device Role: Parallel-connected TVS across output terminals to prevent overvoltage damage to LED strings and driver FETs. Use Value: Clamps transients to 287V with sub-ns response, avoiding thermal runaway in high-power LEDs during surge events. | Use Scenario: Low-voltage analog interface (e.g., RS-485 receiver inputs) connected to long external cables in building management systems. IC Role / Device Role: Primary protection stage before integrated ESD diodes, absorbing bulk surge energy before it reaches sensitive transceivers. Use Value: Handles 1500W pulses without degradation, reducing stress on secondary on-chip protection and extending system MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ200A | Same DO-214AC (SMA) package; 200V VBR min/max tighter (185–215V); lower PPK (400W) | Lower surge rating suits consumer-grade I/O; not rated for ISO 7637-2 Pulse 5a load-dump | Select for cost-sensitive, non-automotive designs where 400W peak power suffices |
| Vishay 1.5SMC200C | DO-214AB (SMC) package; identical 1500W rating and VBR range (180–220V); AEC-Q101 qualified | Same automotive qualification level but larger SMC footprint requires PCB layout change | Choose when DO-201 lead spacing is incompatible with existing assembly process or thermal pad constraints |
Compared with 1.5KE200C, SMAJ200A offers smaller size but reduced surge robustness, while 1.5SMC200C matches performance and qualification at the cost of larger board area - making 1.5KE200C optimal for space-constrained, ISO-compliant automotive power rail protection.

FAQ
What is the maximum clamping voltage of the 1.5KE200C under standard test conditions?
The 1.5KE200C has a maximum clamping voltage (VC) of 287V when subjected to a 10/1000μs surge waveform at 5.4A peak pulse current (IPP). This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5KE200C suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 1.5KE200C is AEC-Q101 qualified when ordered with the "H" suffix (e.g., 1.5KE200CH). The base 1.5KE200C part meets all electrical and mechanical specifications of the AEC-Q101 standard, including temperature cycling, humidity testing, and surge endurance - making it appropriate for engine control, body electronics, and ADAS power rail protection.
How does the 1.5KE200C differ from bidirectional variants like 1.5KE200CA?
The 1.5KE200C is unidirectional and features a cathode band for polarity-sensitive placement, while 1.5KE200CA is bidirectional with symmetrical breakdown in both directions and no polarity marking. The 1.5KE200C is used in DC-biased lines (e.g., 12V power rails), whereas 1.5KE200CA suits AC-coupled or floating signal lines like RS-485 or CAN bus stubs.
What is the working stand-off voltage (VWM) of the 1.5KE200C, and why is it important?
The 1.5KE200C has a working stand-off voltage (VWM) of 162V, meaning it remains in high-impedance blocking mode below this voltage with leakage <1µA. This parameter ensures minimal power loss and signal interference during normal operation while guaranteeing reliable clamping onset just above expected system maxima - essential for protecting 24V industrial or 48V telecom rails.
Can the 1.5KE200C be used in place of older 1N6267-series TVS diodes?
Yes, the 1.5KE200C is a direct functional replacement for legacy 1N6267-series parts with equivalent VBR, VC, and PPK ratings. It maintains identical DO-201 packaging, pinout, and thermal characteristics, allowing drop-in substitution in existing designs - provided the original design accounted for 200V-class clamping and 1500W surge capability.
