Product details
Overview
1V5KE200CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-201 package, rated for 1500W peak pulse power at 1.0ms, with breakdown voltage 190–210V, clamping voltage 274V at 5.5A, and reverse stand-off voltage 171V. It protects power rails and signal lines in industrial motor drives and AC/DC front-end circuits against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE200CA datasheet, 1V5KE200CA pinout, 1V5KE200CA application, or 1V5KE200CA equivalent, key selection criteria include verified bidirectional clamping performance, DO-201 mechanical compatibility, 175°C junction temperature rating, and compliance with IEC 61000-4-2/4-4/4-5 immunity standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1MΩ at 171V), then rapidly avalanches when transient voltage exceeds VBR (190–210V), limiting downstream voltage to ≤274V at 5.5A peak pulse current. Its glass-passivated junction ensures stable leakage (<5μA at 171V) and repeatable breakdown behavior.
The device is designed for unidirectional or bidirectional use-suffix "CA" confirms bipolar configuration with symmetrical electrical characteristics in both directions. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for harsh-environment PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190V / 210V - defines precise avalanche initiation window for reliable overvoltage triggering |
| VRWM | 171V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 274V @ 5.5A - clamped voltage seen by protected circuit during worst-case 1.0ms surge |
| PPPM | 1500W - peak surge power handling capability per JEDEC standard waveform (10/1000μs) |
| IR @ VRWM | <5μA - low leakage preserves system efficiency and avoids false trips in high-impedance nodes |
| TJ max | 175°C - enables operation in enclosed industrial enclosures without derating below full power |
| Package | DO-201 - industry-standard axial-leaded package with 0.375" lead length, UL 94V-0 molding |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; for 1V5KE200CA (bidirectional), polarity is non-directional-leads are interchangeable. Cathode band is omitted on CA-suffix parts per manufacturer marking diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient return path (bidirectional) | Connected to ground or common reference; conducts surge current in either polarity |
| Cathode (Lead 2) | Transient return path (bidirectional) | Electrically identical to Lead 1; no functional distinction in CA configuration |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability of VBR and low parameter drift across thermal cycling and humidity exposure |
| 1500W peak pulse power (1ms) | Withstands 6kV/3A lightning surge per IEC 61000-4-5 Level 4 without degradation |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts up to 5kHz repetition) |
| RoHS + halogen-free (IEC 61249-2-21) | Complies with EU environmental directives and supports lead-free reflow soldering processes |
| Fast response time (<1ps) | Activates before sensitive downstream ICs (e.g., gate drivers, MCU I/O) experience damaging overvoltage |
Applications
| Industrial Motor Drives | AC/DC Power Supplies |

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 PPPM (600W), smaller SMB package (surface-mount), VC = 324V @ 1.9A | Better suited for space-constrained PCBs; lower surge capacity limits use in high-energy AC mains | Select when board area is critical and surge energy is ≤600W; verify thermal relief for repeated events |
| 1N6299A | Same family, same DO-201 package, but unidirectional (no "C" suffix); VRWM = 128V, VC = 207V @ 7.2A | Requires correct polarity placement; unsuitable for AC-coupled or floating differential lines | Choose only for DC-only rails where polarity is fixed and lower clamping voltage is prioritized |
Compared with SMBJ200CA and 1N6299A, the 1V5KE200CA delivers higher surge robustness in through-hole form factor and true bidirectional symmetry-critical for protecting AC inputs, transformer-coupled interfaces, and floating sensor bridges without polarity constraints.

FAQ
What is the clamping voltage of the 1V5KE200CA under a 1.0ms surge?
The 1V5KE200CA clamps to a maximum of 274V when subjected to its rated peak pulse current of 5.5A under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and guarantees protection margin for downstream components rated for ≤300V absolute maximum. The 1V5KE200CA maintains this clamping performance across its full operating temperature range (−55°C to +175°C).
Is the 1V5KE200CA truly bidirectional, and how is that indicated in the part number?
Yes-the "CA" suffix in 1V5KE200CA explicitly denotes a bidirectional configuration, confirmed in TSC's datasheet Section 2 ("Devices for Bipolar Applications"). Electrical characteristics-including VBR, VRWM, and VC-are identical in both directions, and the DO-201 package omits the cathode band marking. This makes the 1V5KE200CA suitable for AC line protection and floating differential interfaces where polarity reversal occurs.
Can the 1V5KE200CA replace a unidirectional 1V5KE200A in an existing design?
No-the 1V5KE200CA cannot directly replace the unidirectional 1V5KE200A without layout review. While both share identical VBR and package, the 1V5KE200A requires correct anode/cathode orientation and exhibits asymmetric behavior (e.g., forward conduction). Using the 1V5KE200CA in its place eliminates polarity concerns but may alter leakage paths in DC-biased circuits. Verify bias conditions and grounding topology before substitution.
What is the maximum allowable ambient temperature for continuous operation of the 1V5KE200CA?
The 1V5KE200CA supports continuous operation up to +75°C ambient when mounted with 0.375" lead length, per its 5W power dissipation rating. Above this, derating is required per Figure 5 (Steady State Power Derating Curve). Its 175°C maximum junction temperature allows short-term surge operation even in high-ambient environments, provided thermal mass and PCB copper area adequately dissipate transient energy.
Does the 1V5KE200CA meet RoHS and halogen-free requirements?
Yes-the 1V5KE200CA complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The epoxy molding compound contains no brominated flame retardants or chlorine-based additives, and terminal plating uses pure tin (no lead, antimony, or bismuth). Full compliance documentation is available from Taiwan Semiconductor upon request for 1V5KE200CA.
