Product details
Overview
1.5KE82CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) in DO-201 package, with nominal breakdown voltage 82V, clamping voltage 118V at 13A peak pulse current, and working stand-off voltage 66.4V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE82CA R0G datasheet, 1.5KE82CA R0G pinout, 1.5KE82CA R0G application, or 1.5KE82CA R0G equivalent, key selection criteria include bidirectional clamping capability, 10/1000μs surge rating, AEC-Q101 qualification status, junction temperature range (–55°C to +175°C), and DO-201 mechanical compatibility.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance across positive and negative transients. Its low dynamic impedance and sub-5ns response time ensure rapid voltage limiting during fast electrical fast transients (EFT).
The device meets ISO 7637-2 immunity requirements for automotive electronics and supports steady-state power dissipation of 5W at TL = 75°C on a 16mm × 16mm copper pad. Junction temperature remains within –55°C to +175°C under rated surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8V / 90.2V @ IT = 1mA - defines reliable conduction onset window for bidirectional clamping |
| VWM | 66.4V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1µA |
| VC @ IPP | 118V @ 13A - peak clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPK | 1500W - non-repetitive surge power handling per JEDEC standard waveform |
| Junction Temp | –55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| Package | DO-201 - industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 |

IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector interface to divert ESD and lightning-induced surges. Use Value: Provides <1µA leakage at 66.4V, ensuring minimal impact on sensor biasing while clamping ±118V transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ85CA | 600W rating, SMA package, VC = 129V @ 9.5A, VWM = 72.2V | Lower surge capacity; surface-mount only; unsuitable for high-energy load dump | Select when board space is constrained and surge energy is ≤600W |
| ON Semiconductor 1.5SMC82CA | 1500W rating, SMC package, VC = 118V @ 13A, VWM = 66.4V, same electrical specs | Surface-mount alternative with identical clamping but different thermal profile and mounting method | Select when automated assembly and higher thermal mass on PCB are preferred over axial leads |
Compared with 1.5KE82CA R0G, SMAJ85CA offers smaller footprint but reduced surge margin, while 1.5SMC82CA matches its 1500W/118V performance in an SMT package-enabling layout flexibility without compromising clamping behavior.

FAQ
What does the 'CA' suffix indicate in 1.5KE82CA R0G?
The 'CA' suffix in 1.5KE82CA R0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This distinguishes it from unidirectional variants (e.g., 1.5KE82A), which require correct polarity orientation. The 1.5KE82CA R0G is intended for AC-coupled or floating DC applications where polarity reversal may occur.
Is 1.5KE82CA R0G AEC-Q101 qualified?
The base 1.5KE82CA R0G variant is not explicitly AEC-Q101 qualified per the provided documentation; however, the 'H' suffix version (e.g., 1.5KE82CAH) is designated as AEC-Q101 qualified. Customers requiring automotive-grade reliability must specify the 'H' suffix. The 1.5KE82CA R0G shares identical electrical parameters and DO-201 packaging but lacks the extended stress test validation required for AEC-Q101 certification.
What is the maximum clamping voltage of 1.5KE82CA R0G under surge conditions?
The maximum clamping voltage (VC) of 1.5KE82CA R0G is 118V at a peak pulse current (IPP) of 13A, measured using the standard 10/1000μs double-exponential waveform. This value ensures downstream components see no more than 118V during worst-case surge events, making it suitable for protecting 80V-rated power stages and interfaces.
How does 1.5KE82CA R0G compare to unidirectional 1.5KE82A in circuit implementation?
Unlike the unidirectional 1.5KE82A, the 1.5KE82CA R0G requires no polarity alignment during placement - its symmetrical structure allows direct connection across any two nodes needing bidirectional protection. This simplifies layout for AC lines, differential buses, or floating grounds. However, it cannot replace 1.5KE82A in circuits relying on forward conduction for DC biasing or rectification functions.
What is the leakage current specification for 1.5KE82CA R0G at its working voltage?
At its working stand-off voltage (VWM) of 66.4V, the maximum blocking leakage current (ID) for 1.5KE82CA R0G is 1µA. This low leakage ensures minimal power loss and negligible loading on sensitive analog or low-power circuits, supporting accurate voltage monitoring and stable biasing in precision sensor or control applications.
