Product details
Overview
1.5KE200A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 200V, clamping voltage of 274V at 5.7A peak pulse current, and DO-201 axial package. It delivers fast response (<1.0ps), low dynamic impedance, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity in power supply rails and DC input protection.
For engineers reviewing the 1.5KE200A datasheet, 1.5KE200A pinout, 1.5KE200A application, or 1.5KE200A equivalent, this part is selected for high-energy surge suppression in 24V/48V industrial control inputs, automotive body electronics, and telecom power interfaces where VWM = 171V, TJ(max) = 175°C, and AEC-Q101 qualification (H-suffix variant) is required.
Technical Context
The 1.5KE200A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 190–210V breakdown range at 1mA test current. Its clamping action limits transient voltages to ≤274V under 10/1000μs waveform, sustaining up to 1500W non-repetitive peak power at 25°C ambient.
Thermal derating applies above 25°C per Fig.2; steady-state power dissipation is 5W at TL = 75°C on 16mm × 16mm copper pad. Junction temperature range is −55°C to +175°C, and forward voltage is 5.0V max at 50A for VBR > 200V devices - confirmed for 1.5KE200A per note 3 in Absolute Maximum Ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 190–210V - ensures reliable turn-on before system-level overvoltage damage occurs in 200V-class DC rails |
| VWM | 171V - maximum continuous reverse operating voltage; sets safe margin below VBR min for stable standby leakage |
| VC @ IPP = 5.7A | 274V - clamped voltage during 10/1000μs surge; defines worst-case stress on downstream ICs |
| PPK | 1500W - peak pulse power handling capability; supports single-event transients up to ISO 7637-2 Pulse 5a |
| IPP | 5.7A - peak impulse current at VC; determines minimum PCB trace width and fuse coordination |
| Junction Temp Range | −55°C to +175°C - enables deployment in under-hood automotive and industrial environments without thermal shutdown |
| Leakage @ VWM | <1μA - negligible standby power loss; critical for battery-backed or low-power monitoring circuits |
Pinout & Package
Package: DO-201 axial leaded case with cathode band marking; RoHS-compliant, halogen-free molding compound (UL 94V-0); pure tin-plated leads solderable per J-STD-002; weight ≈ 0.090g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return; forms current path during reverse-biased clamping |
| Cathode | Protected line input | Connected to protected circuit node (e.g., 24V rail); blocks VWM in normal operation, avalanches at VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (H-suffix) | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock per AEC standard |
| 10/1000μs surge rating | 1500W peak power handling - meets ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Level 4 requirements |
| Clamping ratio (VC/VBR) | ~1.45 - low ratio ensures minimal overvoltage overshoot during fast transients, protecting sensitive 3.3V/5V logic |
| Response time | <1.0ps - sub-picosecond turn-on enables suppression before ESD or lightning-induced edges propagate into ICs |
| Low dynamic impedance | Ensures stable clamping voltage across varying surge amplitudes - critical for consistent protection margin |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |

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; lower PPK = 400W; VC = 324V @ 1.2A; higher VWM = 171V identical | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients (IEC 61000-4-5 Level 2) | Select only if board space constraints prohibit DO-201 and surge energy is ≤400W |
| Vishay 1N6303A | Identical electrical specs (VBR, VC, PPK, package); same JEDEC type; manufactured by Vishay, not Taiwan Semiconductor | No functional difference; validated drop-in replacement per manufacturer cross-reference | Preferred for dual-sourcing; identical performance and footprint - no design change required |
Compared with 1.5KE200A, SMAJ200A offers smaller footprint but sacrifices 73% peak power handling and clamping performance, while 1N6303A provides identical specification compliance and direct second-source availability without layout or BOM revision.

FAQ
What is the maximum clamping voltage of the 1.5KE200A under standard test conditions?
The 1.5KE200A has a maximum clamping voltage (VC) of 274V at 5.7A peak pulse current using the 10/1000μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during a surge event - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1.5KE200A unidirectional or bidirectional, and how is polarity identified?
The 1.5KE200A is a unidirectional TVS diode, indicated by the absence of "CA" suffix and confirmed by its single cathode band marking on the DO-201 package. The banded end is the cathode and must be connected toward the protected line (e.g., 24V rail), while the anode connects to ground - enabling conduction only during reverse overvoltage events.
Does the 1.5KE200A meet AEC-Q101 qualification, and what does the "A" suffix signify?
The "A" suffix in 1.5KE200A denotes tighter parameter tolerances (VBR = 190–210V vs. 180–220V for non-A), but AEC-Q101 qualification requires the "H" suffix (e.g., 1.5KE200AH). Standard 1.5KE200A is not AEC-Q101 qualified; engineers requiring automotive grade must specify the H-suffix variant per ordering code table.
What is the thermal derating behavior of the 1.5KE200A above 25°C ambient temperature?
The 1.5KE200A follows linear derating per Fig.2 in the datasheet: peak pulse power decreases from 1500W at 25°C to zero at 175°C junction temperature. At 75°C ambient, it retains ~80% of rated power when mounted on a 16mm × 16mm copper pad; derating must be applied in thermal simulations for sustained surge duty cycles.
How does the 1.5KE200A compare to the 1.5KE200 (non-A) version in terms of electrical performance?
The 1.5KE200A offers tighter VBR tolerance (190–210V) versus 1.5KE200 (180–220V), resulting in more predictable turn-on behavior and reduced variation in clamping voltage across production lots. All other parameters - including VC, PPK, IPP, and package - are identical between 1.5KE200A and 1.5KE200.
