Product details
Overview
1.5KE6V8CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 6.45V minimum breakdown voltage, 10.5V maximum clamping voltage at 143A peak pulse current, and DO-201 axial package with glass-passivated junction - used in automotive body control modules to protect CAN transceivers from ESD and load dump.
For engineers reviewing the 1.5KE6V8CA-T datasheet, 1.5KE6V8CA-T pinout, 1.5KE6V8CA-T application, or 1.5KE6V8CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, unidirectional vs. bidirectional polarity requirements, thermal derating above +25°C, and compliance with AEC-Q101 stress testing for automotive deployment.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with a reverse standoff voltage of 5.80V and breakdown triggered at 6.45V (min) under 10mA test current. Its fast response time (<1ps) and low dynamic impedance ensure effective suppression of EFT (IEC 61000-4-4) and ESD (IEC 61000-4-2) transients.
The device uses a glass-passivated silicon junction to achieve stable leakage performance (≤1000μA at 5.80V) and high surge robustness - sustaining 200A non-repetitive forward surge current and operating from –55°C to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms waveform - sustains single-event surges up to 143A without failure |
| Clamping Voltage | 10.5V max at 143A IPP - limits voltage seen by downstream 5V/3.3V logic during transients |
| Breakdown Voltage | 6.45V min @ 10mA - ensures reliable triggering before protected circuit exceeds absolute max rating |
| Reverse Standoff | 5.80V - defines maximum continuous DC voltage applied without significant leakage |
| Leakage Current | ≤1000μA @ 5.80V - avoids excessive quiescent power loss in battery-powered systems |
| Operating Temp | –55°C to +175°C - qualified for under-hood automotive environments and industrial motor drives |
Pinout & Package
Package: DO-201 axial leaded package with tin-plated leads, 1.12g mass, UL 94V-0 epoxy molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to lower-potential side of protected line; forms symmetrical clamp path with cathode |
| Cathode | Current entry point in reverse bias | Connected to higher-potential side; enables bidirectional clamping without external polarity assignment |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable leakage and breakdown parameters across temperature and long-term operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | 600W rating, SMB surface-mount package, 11.2V clamping at 53.5A | Lower power handling; suited for space-constrained PCBs where 1500W surge is not required | Select when board area is limited and peak surge energy is ≤0.75J (per 1.0ms pulse) |
| 1.5SMC6.8CA | Same 1500W rating but SMC package, 10.5V clamping, 143A IPP, RoHS-compliant | Surface-mount alternative with identical electrical specs but different thermal profile and mounting method | Choose for automated assembly and improved thermal coupling to copper pour versus axial leads |
Compared with 1.5KE6V8CA-T, SMBJ6.8CA offers smaller footprint at reduced surge capacity, while 1.5SMC6.8CA delivers identical protection in an SMT format - enabling layout flexibility without compromising clamping performance or reliability.

FAQ
What does the "CA" suffix indicate in 1.5KE6V8CA-T?
The "CA" suffix denotes a bidirectional TVS configuration, meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. This differs from "A"-suffixed unidirectional versions that require correct anode/cathode orientation relative to the protected line's reference potential.
Is 1.5KE6V8CA-T still in active production?
No - Diodes Incorporated has marked 1.5KE6V8CA-T as obsolete and discontinued per DS21503 Rev. 12 (May 2023). Aetrix Electronics maintains legacy inventory and supports last-time-buy programs, with cross-reference guidance to active alternatives like 1.5SMC6.8CA.
How does the DO-201 package affect thermal performance?
The DO-201 axial package relies on lead conduction for heat dissipation, delivering 5.0W steady-state power at 75°C lead temperature. Its thermal resistance from junction-to-ambient is ~60°C/W in free air, requiring careful PCB layout with thermal relief cuts and adequate copper area if operated near PD limits.
Can 1.5KE6V8CA-T replace a unidirectional TVS in a DC circuit?
Yes, but only if the protected circuit is referenced to ground and experiences transients of either polarity - such as in LIN or CAN bus lines. In pure DC applications with fixed polarity, a unidirectional part may offer tighter clamping margin and lower leakage, making direct substitution non-optimal without re-evaluation.
