Product details
Overview
1.5KE160CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 136V reverse standoff voltage (VRWM), 152V minimum breakdown voltage (VBR), 219V maximum clamping voltage (VC) at 6.8A peak pulse current, and operates across –55°C to +175°C. It is used in industrial power supplies to protect rectifier outputs against lightning-induced surges.
For engineers reviewing the 1.5KE160CA-T datasheet, 1.5KE160CA-T pinout, 1.5KE160CA-T application, or 1.5KE160CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD rails, unidirectional vs. bidirectional polarity requirements, DO-201 axial lead thermal derating, and IEC 61000-4-5 surge compliance validation.
Technical Context
This bidirectional TVS diode uses glass-passivated silicon junctions to achieve fast response time (<1.0 ps) and stable clamping under repetitive 8/20 µs surge waveforms. Its symmetrical avalanche structure enables equal clamping in both polarities without external biasing.
The device complies with RoHS 3 (2015/863/EU), is halogen- and antimony-free ("Green"), and rated for 1500W non-repetitive peak pulse power at 1.0 ms. It is not AEC-Q200 qualified but meets industrial temperature and flammability (UL 94V-0) requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W - Sustains single 1.0 ms 8/20 µs surge events without failure |
| Reverse Standoff Voltage | 136 V - Maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage | 152–168 V - Avalanche conduction initiates within this range at 1.0 mA test current |
| Clamping Voltage | 219 V - Maximum voltage seen by protected circuit at 6.8 A peak pulse current |
| Operating Temperature | –55°C to +175°C - Enables use in high-ambient environments like motor drive enclosures |
| Package | DO-201 - Axial-leaded, epoxy-molded package with 1.12 g mass and UL 94V-0 rating |
Pinout & Package
1.5KE160CA-T is housed in a DO-201 axial-leaded package with two terminals: anode and cathode. As a bidirectional device, it has no polarity marking; both leads are functionally identical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during negative transients | Connects to line or signal node requiring bidirectional surge clamping |
| Cathode | Current entry point during positive transients | Same physical terminal as anode; symmetric conduction eliminates orientation dependency |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable leakage performance and long-term reliability under thermal cycling |
| Bidirectional clamping symmetry | Eliminates need for polarity-aware placement in AC-coupled or floating bus protection |
| 1500W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4 kV line-to-earth) surge immunity without cascading failure |
| Lead-free, RoHS 3 & "Green" compliant | Fulfills environmental compliance for industrial and consumer end equipment without exemptions |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module Inputs |
|---|---|
|

IC Role / Device Role / Timing Role: Parallel-mounted TVS across DC bus capacitors near power stage. Use Value: Absorbs up to 1500 W transient energy, limiting voltage rise to safe margin below 450 V IGBT blocking rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Lower peak power (600 W), smaller SMB package, 219 V clamping same | Not suitable for >1 kA surge events; limited thermal mass for repeated surges | Select when board space is constrained and surge duty cycle is low |
| 1.5SMC160CA | Same 1500 W rating, SMC package, 219 V clamping, but surface-mount only | Requires reflow-compatible PCB layout; no axial through-hole mounting option | Select when automated assembly and higher density are prioritized over manual repairability |
Compared with SMBJ160CA and 1.5SMC160CA, the 1.5KE160CA-T offers axial-leaded mechanical robustness for high-vibration environments and superior heat dissipation via lead-frame conduction-critical for sustained surge duty in industrial power systems.

FAQ
What does the "CA" suffix indicate in 1.5KE160CA-T?
The "CA" suffix denotes a bidirectional TVS configuration, meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional "A" variants, it has no cathode band marking and functions identically regardless of terminal orientation in the circuit.
Can 1.5KE160CA-T replace a unidirectional 1.5KE160A-T in existing designs?
No-direct replacement is not recommended. The 1.5KE160A-T is unidirectional and requires correct anode/cathode orientation to clamp only positive transients. Substituting the bidirectional CA version may cause unintended conduction during normal negative-biased operation, especially in DC circuits with reverse-polarity protection.
Is 1.5KE160CA-T qualified to AEC-Q200 for automotive use?
No. While Diodes offers AEC-Q200-qualified TVS devices, the 1.5KE160CA-T is not certified to that standard. It meets industrial temperature and flammability requirements but lacks PPAP documentation, change control, and stress-test validation required for automotive ECUs or body electronics.
How does the DO-201 package affect thermal performance compared to SMC or SMB packages?
The DO-201's axial leads provide greater thermal path length to ambient and PCB copper, enabling better steady-state power dissipation (5.0 W at TL = 75°C) than surface-mount equivalents. However, its larger footprint and manual assembly requirement trade off against SMC/SMB density and reflow compatibility.
