Product details
Overview
1.5KE160C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 160V, working stand-off voltage 130V, clamping voltage 230V at 6.8A peak pulse current, and junction temperature range −55°C to +175°C - used for automotive load-dump and inductive switching protection in power supply rails.
For engineers reviewing the 1.5KE160C datasheet, 1.5KE160C pinout, 1.5KE160C application, or 1.5KE160C equivalent, key selection criteria include unidirectional polarity, 130V VWM rating, 230V VC clamping performance, AEC-Q101 qualification status, and DO-201 mechanical compatibility with high-surge PCB layouts.
Technical Context
The 1.5KE160C operates as a unidirectional avalanche diode, triggering at VBR = 144–176V (tested at 1mA), clamping transients to ≤230V within nanoseconds. Its low dynamic impedance ensures rapid energy diversion during ISO 7637-2 Pulse 1/2a/2b/3a/3b events.
Designed for non-repetitive 10/1000μs surge waveforms, it delivers 1500W peak pulse power at 25°C with thermal derating above ambient - supported by 0.090g mass, UL 94V-0 molding compound, and pure tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 144 V / 176 V - breakdown occurs within this range at 1 mA test current |
| VC @ IPP | 230 V at 6.8 A - clamped voltage during full 1500W surge, defining protected circuit stress level |
| PPK | 1500 W - peak pulse power handling per 10/1000μs waveform, critical for load-dump immunity |
| TJ max | +175 °C - maximum junction temperature enabling under-hood automotive deployment |
| ID @ VWM | <1 μA - leakage current at rated stand-off voltage, minimizing standby power loss |
| Package | DO-201 - axial-leaded through-hole package with cathode band marking, compatible with legacy PCB footprints |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking on one end. Cathode terminal is marked; anode is unmarked. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| 1500W surge capability | Withstands ISO 7637-2 Pulse 5a (load dump) up to 1500W without degradation |
| Clamping voltage ≤230V | Limits downstream IC stress during 6.8A transient, preserving 200V+ rated components |
| Response time <1.0 ps | Sub-nanosecond turn-on enables protection of fast-edge digital interfaces and microcontrollers |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive for green manufacturing |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Suppressing 12V/24V battery line transients caused by alternator load dump or relay switching in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and regulator input to clamp spikes before LDO or DC-DC stage. Use Value: Prevents latch-up or destruction of downstream PMICs and MCUs by limiting voltage to 230V during 1500W surges. | Use Scenario: Protecting gate drivers and bus capacitors from inductive kickback in 48V industrial motor control inverters. IC Role / Device Role / Timing Role: Mounted across DC bus terminals to absorb energy from IGBT/MOSFET turn-off spikes. Use Value: Enables reliable operation at TJ = 175°C ambient, reducing need for heatsinking while meeting IEC 61800-3 surge immunity. |
| LED Driver Input Stage | Telecom Power Interface |
Use Scenario: Safeguarding constant-current LED driver ICs against line surges in streetlight and signage applications. IC Role / Device Role / Timing Role: Placed upstream of input filter capacitor to shunt transients before rectifier and controller. Use Value: Maintains <1μA leakage at 130V VWM, avoiding unnecessary power loss in always-on lighting systems. | Use Scenario: Front-end protection for PoE-powered equipment exposed to lightning-induced surges on Ethernet cables. IC Role / Device Role / Timing Role: Paired with common-mode chokes and gas discharge tubes to handle differential-mode transients on DC bias lines. Use Value: Fast response (<1ps) and low clamping voltage ensure Ethernet PHY ICs remain within absolute maximum ratings during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Surface-mount SMB package; 160V VBR, 230V VC, 600W PPK - lower power rating, smaller footprint | Used where board space is constrained and surge energy is ≤600W (e.g., secondary-side protection) | Select SMBJ160A only when layout prohibits axial DO-201 or when total surge energy is below 600W |
| 1.5KE160CA | Bidirectional variant; same VBR/VC specs but symmetric conduction in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose 1.5KE160CA only if bidirectional clamping is needed; 1.5KE160C is optimal for DC rail protection with defined polarity |
Compared with SMBJ160A, the 1.5KE160C offers 2.5× higher surge power (1500W vs. 600W) and proven DO-201 mechanical robustness for high-vibration environments; compared with 1.5KE160CA, it provides lower leakage and tighter VBR tolerance for unidirectional DC applications.

FAQ
What is the polarity configuration of the 1.5KE160C?
The 1.5KE160C is a unidirectional TVS diode, with cathode identified by a band on the DO-201 package. It conducts only when the cathode is at a higher potential than the anode - making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like 1.5KE160CA, which protect both positive and negative transients.
Does the 1.5KE160C meet AEC-Q101 requirements?
Yes, the 1.5KE160C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge - validating its suitability for automotive under-hood applications such as engine control units and body electronics.
What is the maximum clamping voltage of the 1.5KE160C during a surge event?
The 1.5KE160C has a maximum clamping voltage (VC) of 230 V at 6.8 A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 1500W transient, ensuring downstream components rated above 230V remain within safe operating limits.
How does the 1.5KE160C compare to the 1.5KE160A variant?
The 1.5KE160C and 1.5KE160A share identical electrical specifications including VBR (144–176 V), VWM (130 V), and VC (230 V), but differ in marking and minor process controls. The "C" suffix denotes standard commercial grade, while "A" indicates tighter VBR tolerance (152–168 V) and enhanced screening - both use DO-201 packaging and are unidirectional.
Can the 1.5KE160C be used in surface-mount designs?
No, the 1.5KE160C is exclusively available in the axial-leaded DO-201 through-hole package and is not compatible with surface-mount assembly processes. For SMT alternatives, consider the SMBJ160A (SMB package, 600W) or SMCJ160A (SMC package, 1500W), which offer comparable voltage ratings but require different PCB footprints and reflow profiles.
