Overview
1.5KE160CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 160V nominal breakdown voltage (VBR min 144V, max 176V), 130V working stand-off voltage (VWM), 230V maximum clamping voltage (VC) at 6.8A peak impulse current, and <1μA leakage above 10V - designed for automotive-grade ESD and load-dump protection in power supply rails and interface lines.
For engineers reviewing the 1.5KE160CA datasheet, 1.5KE160CA pinout, 1.5KE160CA application, or 1.5KE160CA equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, DO-201 mechanical data, and real-world design guidance for high-energy transient suppression in harsh environments.
Technical Context
The 1.5KE160CA is a bipolar (bidirectional) TVS diode optimized for unidirectional and bidirectional surge immunity without polarity dependency. It exhibits low dynamic impedance and sub-nanosecond response time (<1ps from 0V to VBR), enabling effective clamping of fast transients such as EFT and ISO 7637-2 pulses.
Its 1500W peak pulse power rating (10/1000μs waveform), 175°C maximum junction temperature, and DO-201 package with pure tin-plated leads support robust operation in automotive and industrial power systems where thermal cycling and mechanical reliability are critical.
Key Specifications

FAQ
What is the clamping voltage of the 1.5KE160CA under a 10/1000μs surge?
The 1.5KE160CA clamps to a maximum of 230 V when subjected to a 10/1000μs waveform at 6.8 A peak impulse current (IPP), as specified in the Electrical Specifications table. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The 1.5KE160CA maintains this clamping performance across its full operating temperature range up to +175°C junction temperature.
Is the 1.5KE160CA unidirectional or bidirectional?
The 1.5KE160CA is a bidirectional TVS diode, indicated by the "CA" suffix per the 1.5KE series naming convention. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines, floating buses, and differential signal pairs. Unlike unidirectional variants (e.g., 1.5KE160A), the 1.5KE160CA does not feature a cathode band marking and functions identically in either orientation.
Does the 1.5KE160CA meet AEC-Q101 qualification standards?
Yes, the 1.5KE160CA is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version O2104). This qualification confirms successful completion of stress tests including high-temperature operating life, temperature cycling, humidity bias HAST, and mechanical shock - validating its suitability for automotive electronic control units and under-hood applications.
What is the maximum leakage current of the 1.5KE160CA at its working stand-off voltage?
The 1.5KE160CA exhibits a maximum blocking leakage current (ID) of less than 1 μA at its 130 V working stand-off voltage (VWM), as confirmed in the Electrical Specifications table. This ultra-low leakage ensures minimal power loss in always-on systems and prevents signal degradation in high-impedance sensing paths. The specification holds across the full operating temperature range from −55°C to +175°C.
Which international standards does the 1.5KE160CA comply with for automotive transient immunity?
The 1.5KE160CA meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery line transients), and Pulse 3a/3b (switching noise), as documented in the FEATURES section. These compliance statements are based on direct testing per the standard's waveform definitions and amplitude limits, confirming the 1.5KE160CA's ability to protect downstream electronics against real-world automotive electrical disturbances.
