Product details
Overview
1.5KE200 from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 200V, clamping voltage of 287V at 5.4A peak pulse current, and DO-201 package. It delivers robust ESD and surge protection for automotive power rails, industrial I/O interfaces, and DC power supplies exposed to ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE200 datasheet, 1.5KE200 pinout, 1.5KE200 application, or 1.5KE200 equivalent, this page provides verified electrical parameters, clamping performance under 10/1000μs waveform, thermal derating behavior, junction capacitance profile, and AEC-Q101-qualified alternatives - all specific to the 1.5KE200 variant.
Technical Context
The 1.5KE200 operates as a unidirectional avalanche diode, triggering at a minimum breakdown voltage of 180V and maximum of 220V when tested at 1.0mA. Its clamping action limits transient voltages to ≤287V at 5.4A (10/1000μs), with dynamic impedance low enough to sustain 1500W peak pulse power without thermal runaway.
Designed for high-energy transient suppression, it features <1.0ps response time from 0V to VBR, junction temperature range of –55°C to +175°C, and meets UL 94V-0 flammability rating in its DO-201 molded package. Leakage current remains ≤1μA above 171V working stand-off voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0mA | 180–220V: Ensures reliable turn-on before system overvoltage damages downstream ICs. |
| VWM | 162V: Maximum continuous reverse operating voltage; defines safe DC bias margin. |
| VC @ IPP = 5.4A | 287V: Clamped voltage during 10/1000μs surge; determines protected circuit's voltage stress limit. |
| PPK | 1500W: Peak pulse power handling capability; supports high-energy transients per ISO 7637-2. |
| IPP | 5.4A: Maximum non-repetitive peak impulse current; sets minimum trace/solder joint robustness. |
| Junction Temp Range | –55°C to +175°C: Enables operation in under-hood automotive and industrial environments. |
| Package | DO-201: Standard axial-leaded through-hole package with tin-plated leads compliant to J-STD-002. |
Pinout & Package
DO-201 package: Axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance. Weight ≈ 0.090g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-impedance return path; forms current loop during clamping. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 24V rail); blocks VWM until VBR exceeded. |
Key Features

IC Role / Device Role / Timing Role: Unidirectional clamping device across output capacitor, activated only during overvoltage faults. Use Value: Clamps to 287V within <1.0ps, limiting stress on 300V-rated electrolytics and secondary-side MOSFETs. |
Use Scenario: Preventing catastrophic failure of constant-current LED drivers during open-circuit or hot-swap events. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output to absorb inductive energy from long cable runs.

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 200V VBR range (180–220V), but 400W PPK; DO-214AC (SMA) surface-mount package. | Lower surge capacity suits consumer-grade 12V/24V systems; not rated for ISO 7637-2 Pulse 5a (load dump). | Select when board space is constrained and peak surge energy is ≤400W; requires re-layout due to SMD footprint. |
| Vishay 1.5SMC200A | Identical 1500W rating and DO-214AB (SMC) package; VC = 295V @ 5.1A - 8V higher clamping than 1.5KE200. | Slightly higher clamping increases protected IC stress margin; same AEC-Q101 option available. | Choose when DO-214AB mechanical robustness or automated assembly is prioritized over minimal clamping voltage. |
Compared with Littelfuse SMAJ200A and Vishay 1.5SMC200A, the 1.5KE200 offers the lowest clamping voltage (287V) in a through-hole DO-201 package, making it optimal for legacy industrial designs requiring high surge immunity without PCB redesign.

FAQ
What is the exact breakdown voltage range for 1.5KE200?
The 1.5KE200 has a guaranteed breakdown voltage range of 180V to 220V when measured at 1.0mA test current (IT). This range is confirmed in the Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet (Version O2104), where JEDEC type 1N6303 lists VBR(min) = 180V and VBR(max) = 220V. The 1.5KE200A variant tightens this to 190–210V.
Is 1.5KE200 unidirectional or bidirectional?
The 1.5KE200 is a unidirectional TVS diode, indicated by its single cathode band marking and specification of forward voltage (VF = 3.5V @ 50A). Bidirectional variants in the same family carry "CA" suffixes (e.g., 1.5KE200CA) and lack forward voltage ratings. The 1.5KE200 datasheet explicitly states "For Uni-directional only" in the Absolute Maximum Ratings footnote.
What is the clamping voltage of 1.5KE200 at its rated peak current?
The 1.5KE200 clamps to a maximum of 287V when subjected to its rated peak pulse current of 5.4A under the standard 10/1000μs waveform. This value is specified in the Electrical Specifications table for JEDEC type 1N6303 and applies at TA = 25°C. Derating applies above ambient temperatures per Figure 2 in the datasheet.
Does 1.5KE200 meet automotive qualification standards?
The base 1.5KE200 is not AEC-Q101 qualified; however, the pin-compatible 1.5KE200A variant (JEDEC type 1N6303A) is explicitly listed as AEC-Q101 qualified in the Features section and Ordering Information table. Both share identical electrical specs except for tighter VBR tolerance (190–210V) and enhanced reliability screening for automotive under-hood use.
What package type does 1.5KE200 use and what are its key mechanical properties?
The 1.5KE200 uses the DO-201 axial-leaded package, with pure tin-plated leads compliant to J-STD-002 solderability, UL 94V-0 flammability rating, and JESD 201 Class 2 whisker resistance. Its approximate weight is 0.090g, and polarity is marked by a cathode band - critical for correct unidirectional installation in circuits like 24V power rails.
