Product details
Overview
1.5KE160 from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 160 V, minimum VBR of 144 V at 1.0 mA test current, maximum clamping voltage of 230 V at 6.8 A peak pulse current, and DO-201 axial package. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE160 datasheet, 1.5KE160 pinout, 1.5KE160 application, or 1.5KE160 equivalent, key selection criteria include its 160 V standoff rating, 230 V clamping performance under 10/1000 µs surge, AEC-Q101 qualification option (1.5KE160A), low leakage (<1 µA above 130 V), and thermal stability up to 175 °C junction temperature.
Technical Context
The 1.5KE160 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 144–176 V breakdown range. Its low dynamic impedance ensures rapid clamping response-typically <1.0 ps from 0 V to VBR-and it sustains 1500 W non-repetitive peak pulse power per 10/1000 µs waveform.
Designed for high-energy transient suppression in DC power lines, it meets ISO 7637-2 immunity requirements and features pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by cathode band on DO-201 body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 144 V / 176 V at 1.0 mA - defines reliable conduction onset under surge conditions |

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 SMAJ160A | Same 160 V nominal, DO-214AC (SMA) package, 1500 W rating, but 243 V clamping at 6.2 A | Surface-mount footprint; requires PCB rework vs. through-hole DO-201 | Select when board space is constrained and automated assembly is preferred |
| ON Semiconductor 1.5SMC160A | Same 160 V nominal, DO-214AB (SMC) package, 1500 W rating, 243 V clamping at 6.2 A | Larger SMC outline; higher thermal mass but incompatible with DO-201 mounting holes | Choose for higher thermal cycling endurance where mechanical robustness outweighs footprint size |
Compared with 1.5KE160, SMAJ160A offers surface-mount compatibility at the cost of higher clamping voltage and different thermal profile, while 1.5SMC160A provides enhanced power cycling durability but requires layout redesign-neither is pin-compatible due to distinct packages and lead forms.

FAQ
What is the breakdown voltage range of the 1.5KE160?
The 1.5KE160 has a guaranteed breakdown voltage range of 144 V to 176 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, directly supporting its use in 120–160 V DC systems where precise overvoltage thresholding is required. The 1.5KE160 maintains this specification under JEDEC-standard test conditions.
Is the 1.5KE160 unidirectional or bidirectional?
1.5KE160 is a unidirectional TVS diode, intended for DC line protection with polarity-sensitive placement-cathode connected to the protected line, anode to ground. Its datasheet specifies forward voltage (VF = 3.5 V @ 50 A) and does not list bidirectional electrical characteristics. For bidirectional use, the 1.5KE160CA variant must be selected instead.
What is the maximum clamping voltage of the 1.5KE160 during a surge event?
The 1.5KE160 clamps to a maximum of 230 V when subjected to its rated 6.8 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on downstream circuitry during worst-case transient events, ensuring compatibility with 200 V-rated capacitors and 250 V MOSFETs.
Does the 1.5KE160 meet automotive qualification standards?
The base 1.5KE160 is not AEC-Q101 qualified; however, its variant 1.5KE160A is explicitly listed as AEC-Q101 qualified in Taiwan Semiconductor's documentation. The "A" suffix denotes qualification per stress tests including temperature cycling, humidity bias HAST, and accelerated life testing-making 1.5KE160A suitable for automotive power modules, while 1.5KE160 is intended for industrial or commercial applications.
What package type does the 1.5KE160 use, and what are its mechanical features?
The 1.5KE160 uses the DO-201 axial package: a cylindrical epoxy-molded case with tinned copper leads, cathode band marking, UL 94V-0 flammability rating, and 0.090 g typical weight. Its leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance, and thermal performance is specified for mounting on a 16 mm × 16 mm copper pad at 75 °C lead temperature.
