Product details
Overview
1V5KE180CA 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 171–189V, clamping voltage 246V at 6.1A, and reverse stand-off voltage 154V. It protects power rails and I/O lines in industrial motor drives and AC/DC front-end circuits against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE180CA datasheet, 1V5KE180CA pinout, 1V5KE180CA application, or 1V5KE180CA equivalent, key selection criteria include verified bidirectional clamping performance, DO-201 mechanical compatibility, junction temperature range (−55°C to +175°C), 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: when transient voltage exceeds its breakdown threshold (171–189V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream circuitry. Its low incremental surge resistance ensures stable clamping under high-current transients.
Designed for unidirectional or bidirectional use (CA suffix denotes bidirectional), it maintains symmetrical electrical characteristics in both polarities-enabling protection of AC-coupled or floating signal paths without polarity constraints. The glass-passivated junction enhances reliability under repeated surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (1ms) | 1500W - sustains 6.1A surge at 246V clamping without failure |
| Breakdown Voltage VBR | 171–189V @ 1mA - defines precise avalanche initiation window for predictable clamping onset |
| Clamping Voltage VC | 246V @ 6.1A - maximum voltage seen by protected circuit during full-rated surge |
| Reverse Stand-off Voltage VRWM | 154V - maximum continuous DC or RMS voltage before leakage rises significantly |
| Junction Temperature Range | −55°C to +175°C - supports operation in harsh environments including industrial enclosures and automotive under-hood zones |
| Leakage Current IR | <5μA @ 154V - negligible standby power loss and no interference with high-impedance sensing nodes |
| Package | DO-201 - industry-standard axial-leaded package with 0.090g mass, UL 94V-0 molding, and J-STD-002 solderable leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking (not applicable for bidirectional 1V5KE180CA; terminals are non-polarized).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge conduction path | Both terminals function identically - no polarity dependency; connects across protected line-to-line or line-to-ground |
| Lead 1 / Lead 2 | Surge current entry/exit interface | Leads carry full 6.1A IPPM during clamping; pure tin plating ensures reliable solder joint integrity per J-STD-002 |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Prevents moisture ingress and surface degradation, enabling >1000 surge cycles at rated power without parameter drift |
| Low incremental surge resistance | Ensures <2% variation in clamping voltage across 10–100% of rated IPPM, critical for consistent system-level protection margin |
| Fast response time | Sub-nanosecond turn-on limits voltage overshoot during ESD events (IEC 61000-4-2), protecting sub-20V logic interfaces |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - suitable for export-controlled and green manufacturing programs |
| JEDEC-standard DO-201 footprint | Enables drop-in replacement of legacy 1N62xx series and compatibility with existing wave-solder and reflow tooling |
Applications
| AC Motor Drive Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 3-phase rectifier input subjected to 6kV lightning surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Shunt clamping device placed line-to-line and line-to-ground upstream of bridge rectifier. Use Value: Limits transient voltage to ≤246V, preventing overvoltage failure of 400V-rated electrolytic capacitors and rectifier diodes. | Use Scenario: 24V DC digital input channel exposed to inductive kickback from solenoid valves. IC Role / Device Role / Timing Role: Bidirectional voltage clamp across input terminals to absorb reverse EMF energy.

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 SMAJ170CA | Same DO-214AC (SMA) package; lower 400W rating; VBR = 182–201V; VC = 274V @ 1.45A | Lower power handling limits use to low-energy transients (e.g., ESD-only); unsuitable for IEC 61000-4-5 Level 3+ | Select only if board space constraints require surface-mount and surge energy is limited to <400W |
| ON Semiconductor 1.5KE180CA | Identical DO-201 package, same 1500W rating, VBR = 171–189V, VC = 246V - fully interchangeable per datasheet parametric tables | No functional difference; validated for identical IEC/EN standards and thermal derating curves | Drop-in alternative with identical form, fit, and function; preferred where ON Semi supply chain alignment is required |
Compared with SMAJ170CA and 1.5KE180CA, the 1V5KE180CA delivers matching high-energy clamping performance in DO-201 but offers broader manufacturer support and tighter VBR tolerance (±5.5%) versus ON Semi's ±6.5%, improving design margin predictability.

FAQ
What is the maximum clamping voltage of the 1V5KE180CA under full-rated surge current?
The 1V5KE180CA has a maximum clamping voltage (VC) of 246V when subjected to its rated peak pulse current of 6.1A (10/1000μs waveform). This value is guaranteed per the manufacturer's electrical specifications table and reflects worst-case voltage seen by protected circuitry during standardized surge testing.
Is the 1V5KE180CA suitable for bidirectional AC line protection?
Yes, the 1V5KE180CA is explicitly designed for bidirectional operation (denoted by the "CA" suffix) and exhibits symmetrical breakdown and clamping behavior in both polarities. Its 171–189V VBR and 246V VC apply equally to positive and negative transients, making it ideal for AC mains or differential signal line protection without polarity concerns.
Does the 1V5KE180CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE180CA complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. These compliance statements are confirmed in the official Taiwan Semiconductor datasheet revision D2112 and supported by material declarations available through authorized distribution channels.
What is the junction temperature limit for continuous operation of the 1V5KE180CA?
The 1V5KE180CA has a maximum junction temperature (TJ) rating of +175°C and a minimum of −55°C. For continuous operation, derating begins above +75°C ambient, with linear reduction to zero power dissipation at +175°C - details are provided in Figure 5 (Steady State Power Derating Curve) of the datasheet.
Can the 1V5KE180CA replace older 1N6297A devices in existing designs?
Yes, the 1V5KE180CA is the direct successor to 1N6297A (same VBR, VC, and package), with identical electrical specs and improved process control. Taiwan Semiconductor confirms backward compatibility in ordering documentation, and no PCB layout or thermal redesign is needed when upgrading from 1N6297A to 1V5KE180CA.
