Product details
Overview
1.5KE82A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 82V, minimum VBR 77.9V at 1mA, maximum clamping voltage 113V at 13.9A peak pulse current, and working stand-off voltage 70.1V - designed for automotive and industrial power rail protection against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE82A R0G datasheet, 1.5KE82A R0G pinout, 1.5KE82A R0G application, or 1.5KE82A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, AEC-Q101 qualification status, clamping performance under 10/1000μs surge, and direct alternatives for high-energy transient suppression in 12V/24V systems.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 70.1V, then avalanches sharply at VBR = 77.9–86.1V (1mA test), limiting transient energy to ≤113V at 13.9A. Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment.
It delivers 1500W non-repetitive peak pulse power per 10/1000μs waveform, with dynamic impedance low enough to sustain <1.0ps response from 0V to VBR, and leakage current <1μA above 10V - enabling robust ESD and load-dump immunity without loading normal operating circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 77.9V min / 86.1V max - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 70.1V - maximum continuous DC or RMS voltage the device blocks without conduction |
| VC @ IPP = 13.9A | 113V - clamped voltage during full 1500W surge, determining protected circuit's peak stress level |
| PPK | 1500W - peak pulse power handling per 10/1000μs waveform, defining surge energy absorption capacity |
| IPP | 13.9A - maximum non-repetitive peak impulse current the device safely diverts |
| Junction Temp Range | −55°C to +175°C - enables operation in engine compartments and industrial enclosures without derating |
| Leakage @ VWM | <1μA - ensures negligible standby current draw on protected supply rails |
Pinout & Package
Package: DO-201 axial lead package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, UL 94V-0 molded compound, 0.090g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return; establishes reference for clamping action |
| Cathode | High-side transient input | Connected to protected line (e.g., 12V rail); avalanche occurs between cathode and anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per JESD22 |
| 1500W 10/1000μs surge rating | Withstands load dump and alternator transients per ISO 7637-2 without degradation |
| Clamping voltage ≤113V at 13.9A | Ensures downstream 100V-rated ICs remain within safe operating area during worst-case surge |
| Response time <1.0ps | Engages before fast ESD or lightning-induced edges propagate into sensitive analog/digital circuitry |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |

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 SMAJ82A | DO-214AC (SMA) package, 1.5kW rating, VBR = 91.1–100.7V, VC = 135V @ 11.1A | Higher clamping voltage and lower peak current; suited for PCB space-constrained designs where 135V clamping is acceptable | Select when footprint size is critical and system can tolerate higher clamped voltage; not drop-in due to different package and thermal profile |
| ON Semiconductor 1.5SMC82A | DO-214AB (SMC) package, 1.5kW rating, VBR = 91.1–100.7V, VC = 135V @ 11.1A | Same VBR/VC spread as SMAJ82A; higher thermal mass than DO-201 but larger footprint | Choose for improved thermal dissipation in high-ambient environments; requires layout change due to SMC outline and lead spacing |
Compared with 1.5KE82A R0G, SMAJ82A and 1.5SMC82A offer similar power rating but higher clamping voltage (135V vs. 113V) and wider VBR tolerance, making them less precise for tight-margin 100V-system protection - whereas 1.5KE82A R0G's lower VC and DO-201 axial form factor support legacy through-hole designs and stricter clamping requirements.

FAQ
What is the exact breakdown voltage range for 1.5KE82A R0G?
The 1.5KE82A R0G has a guaranteed breakdown voltage range of 77.9V to 86.1V at 1mA test current, per Taiwan Semiconductor's O2104 datasheet revision. This tighter VBR window compared to the non-A version (73.8–90.2V) reflects tighter process control for automotive-grade consistency. The 1.5KE82A R0G must be biased above its VWM of 70.1V to enter avalanche conduction.
Is 1.5KE82A R0G AEC-Q101 qualified?
Yes, 1.5KE82A R0G is AEC-Q101 qualified, as confirmed in the "FEATURES" section and "ORDERING INFORMATION" of the official Taiwan Semiconductor 1.5KE series datasheet (Version O2104). The "A" suffix denotes AEC-Q101 compliance, covering stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - critical for under-hood automotive deployment.
What is the maximum clamping voltage of 1.5KE82A R0G under surge conditions?
The maximum clamping voltage of 1.5KE82A R0G is 113V at 13.9A peak pulse current (IPP), measured using the standard 10/1000μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 1500W transient event - significantly lower than alternatives like SMAJ82A (135V), making 1.5KE82A R0G suitable for 100V-rated components.
Does 1.5KE82A R0G have bidirectional capability?
No, 1.5KE82A R0G is a unidirectional TVS diode, indicated by the absence of "CA" or "C" suffix and explicit listing under "Devices for Unidirectional Applications" in the datasheet. It conducts only when cathode-to-anode voltage exceeds VBR; reverse polarity applied to its terminals will block up to −70.1V (VWM) but not clamp negative transients. For bidirectional protection, use 1.5KE82CA R0G instead.
What package type and marking does 1.5KE82A R0G use?
1.5KE82A R0G uses the DO-201 axial lead package with cathode band marking, per the "MECHANICAL DATA" and "PACKAGE OUTLINE DIMENSIONS" sections. The "R0G" suffix denotes green molding compound (halogen-free) and tape-and-reel packaging (1250 pcs/reel). Lead finish is pure tin, compliant with J-STD-002 for solderability, and the device weighs approximately 0.090g.
