Product details
Overview
1.5KE180CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage of 180V, clamping voltage of 258V at 6.1A peak pulse current, and working stand-off voltage of 146V - designed for automotive-grade ESD and surge protection in power supply rails and signal lines.
For engineers reviewing the 1.5KE180CA datasheet, 1.5KE180CA pinout, 1.5KE180CA application, or 1.5KE180CA equivalent, this part delivers AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-5ns response time, and low dynamic impedance for robust transient immunity in harsh environments.
Technical Context
The 1.5KE180CA operates as a bidirectional avalanche diode, triggering symmetrically in both polarities above its 162–198V breakdown range (VBR @ IT = 1mA), with clamping action limiting transient voltages to ≤258V under 10/1000μs surges up to 1500W. Its junction temperature rating extends from –55°C to +175°C, supporting under-hood automotive deployment.
It features pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band - though omitted in bidirectional configuration, functional symmetry ensures identical performance across terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 198 V - Ensures reliable conduction onset within defined tolerance at 1mA test current, critical for predictable clamping threshold selection. |
| VWM | 146 V - Maximum continuous reverse operating voltage before leakage exceeds 1µA; defines safe DC bias margin below breakdown. |
| VC @ IPP | 258 V at 6.1 A - Peak clamped voltage during 10/1000μs surge; determines maximum stress imposed on protected downstream circuitry. |
| PPK | 1500 W - Single-pulse surge handling capability per JEDEC standard; enables protection against high-energy transients like load dump or inductive kick. |
| TJ max | +175 °C - Maximum junction temperature rating; supports operation in high-ambient environments such as automotive engine compartments. |
| Response time | <5.0 ns - Time from 0V to VBR under bidirectional surge; ensures suppression activation before sensitive ICs experience overvoltage damage. |
| Leakage ID @ VWM | <1 µA - Low standby current minimizes power loss and avoids false triggering in high-impedance sensing or bias networks. |
Pinout & Package
Package: DO-201 axial leaded plastic package with cathode band marking (functionally non-directional for 1.5KE180CA due to bidirectional construction). Dimensions conform to standard JEDEC DO-201 outline; leads are pure tin plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (reversible) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on polarity of transient; no fixed orientation required in PCB layout. |
| Lead 1 / Lead 2 | Current path for surge conduction | Both leads carry equal surge current magnitude in opposite directions; symmetric thermal and electrical behavior ensures balanced PCB trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, UHAST, and mechanical shock - enabling use in safety-critical ECUs. |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery line transients), and Pulse 3a/3b (switching noise) without degradation. |
| Low dynamic impedance | Minimizes voltage overshoot during fast-rising transients by sustaining low clamping impedance across full surge current range. |
| Halogen-free & RoHS | Meets IEC 61249-2-21 halogen-free standard and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life compliance. |
| UL 94V-0 molding | Flame-retardant encapsulation prevents fire propagation in fault conditions, satisfying board-level safety standards for industrial and transportation systems. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Inputs |

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 SMAJ180CA | Same 180V nominal, DO-214AC (SMA) package; lower PPK (400W), higher VC (292V @ 4.3A). | Lower surge rating suits consumer-grade or low-energy interfaces; not AEC-Q101 qualified. | Select when space-constrained layouts require surface-mount and surge demands are ≤400W. |
| ON Semiconductor 1.5SMC180CA | Same 180V nominal, DO-214AB (SMC) package; PPK = 1500W, VC = 258V @ 6.1A, AEC-Q101 qualified. | Identical electrical specs but larger SMC footprint; thermal performance differs due to package geometry and leadframe mass. | Choose when existing SMC footprint compatibility or higher thermal mass is prioritized over DO-201 axial form factor. |
Compared with 1.5KE180CA, SMAJ180CA offers smaller size but reduced surge capacity and no automotive qualification, while 1.5SMC180CA matches all key ratings but requires PCB redesign for SMC mounting - making 1.5KE180CA optimal for axial-leaded, high-reliability automotive and industrial designs.

FAQ
What does the 'CA' suffix indicate in 1.5KE180CA?
The 'CA' suffix in 1.5KE180CA denotes bidirectional configuration - meaning the device functions identically in both polarities, with symmetrical breakdown (162–198V) and clamping (258V) characteristics. This distinguishes it from unidirectional variants (e.g., 1.5KE180A), which have a defined anode/cathode and only conduct in reverse bias.
Is 1.5KE180CA AEC-Q101 qualified?
Yes, 1.5KE180CA is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's documentation and ordering code suffix 'H' (e.g., 1.5KE180CAH). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing, validating suitability for automotive under-hood applications.
What is the maximum clamping voltage of 1.5KE180CA under surge conditions?
The maximum clamping voltage (VC) of 1.5KE180CA is 258 V at 6.1 A peak pulse current (IPP), measured under the standard 10/1000μs double-exponential waveform. This value represents the upper limit of voltage seen by protected circuitry during a full-rated 1500W transient event.
Can 1.5KE180CA be used in place of a unidirectional TVS like 1.5KE180A?
No - 1.5KE180CA is bidirectional and lacks polarity marking for DC-biased applications; substituting it for unidirectional 1.5KE180A may cause unintended conduction in forward bias. Use 1.5KE180CA only where symmetrical transient protection is required, such as AC lines or differential signal pairs.
What packaging options are available for 1.5KE180CA?
1.5KE180CA is supplied in DO-201 axial package, available in tape-and-reel (1,250 pcs) and ammo box (500 pcs) formats. The 'H' variant (1.5KE180CAH) denotes AEC-Q101 qualification but uses the same DO-201 mechanical form factor and lead finish (pure tin plating).
