Product details
Overview
1.5KE6.8A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 6.8V, minimum VBR 6.45V at 10mA, maximum clamping voltage 10.5V at 1000A peak pulse current, and working stand-off voltage 5.80V - designed for automotive-grade ESD and load-dump protection in power supply rails and I/O lines.
For engineers reviewing the 1.5KE6.8A R0G datasheet, 1.5KE6.8A R0G pinout, 1.5KE6.8A R0G application, or 1.5KE6.8A R0G equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (R0G suffix indicates green, halogen-free, RoHS-compliant DO-201), low dynamic impedance, sub-1ps response time, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b.
Technical Context
The 1.5KE6.8A R0G operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 6.45–7.14V breakdown range at 10mA test current. It clamps transients to ≤10.5V at 1000A (10/1000μs waveform), with <1μA leakage above 10V and thermal derating per Fig.2 up to 175°C junction temperature.
Its DO-201 package supports 5W steady-state dissipation at 75°C lead temperature on 16mm×16mm copper pad, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability - enabling robust placement in automotive body control modules and industrial power inputs where fast, high-energy surge suppression is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=10mA | 6.45–7.14V - ensures reliable turn-on before system overvoltage damage occurs |
| VWM | 5.80V - maximum continuous reverse voltage without significant leakage |
| VC @ IPP=1000A | ≤10.5V - limits protected circuit voltage during worst-case 10/1000μs surge |
| PPK | 1500W - handles high-energy transients such as ISO 7637-2 Pulse 1 (inductive switch-off) |
| IPP max | 1000A - peak impulse current capability under standardized surge waveform |
| Junction temp. range | −55°C to +175°C - supports under-hood automotive and industrial ambient conditions |
| Leakage @ VWM | <1μA - negligible standby power loss and signal integrity impact |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; two-terminal device: anode (unmarked end) and cathode (banded end). Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 5V rail); conducts when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity, and mechanical shock per stress test requirements |
| 10/1000μs surge rating | 1500W peak power handling per JEDEC standard - matches real-world load-dump and EFT waveforms |
| Clamping ratio (VC/VBR) | ~1.47 - low ratio ensures minimal overvoltage exposure to downstream ICs |
| Response time | <1.0ps - enables protection of high-speed digital interfaces against ESD events |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - suitable for green manufacturing programs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (ISO 7637-2 Pulse 5a) on 12V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surges before DC-DC converter. Use Value: Limits voltage to ≤10.5V during 1000A pulses, preventing latch-up or gate oxide rupture in upstream regulators. | Use Scenario: Protecting 4–20mA analog sensor outputs from ESD and cable-induced fast transients in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting surge energy to ground before signal conditioning op-amp. Use Value: Sub-1ps response ensures clamping before transient couples into sensitive amplifier inputs, preserving measurement accuracy. |
| LED Driver Input Protection | USB Port VBUS Line Protection |
Use Scenario: Safeguarding constant-current LED drivers from inductive kickback when switching high-side MOSFETs. IC Role / Device Role / Timing Role: Placed across driver input terminals to absorb reverse-recovery energy from flyback diodes. Use Value: 1500W rating absorbs repetitive 10/1000μs spikes without degradation, extending driver lifetime. | Use Scenario: Guarding USB 2.0 VBUS (5V) line against contact ESD (IEC 61000-4-2 ±15kV air) in embedded host devices. IC Role / Device Role / Timing Role: Unidirectional TVS connected between VBUS and ground, with cathode to VBUS. Use Value: 5.80V VWM allows normal 5V operation while clamping ESD to ≤10.5V - below USB PHY absolute max rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | DO-214AA (SMB) package, 600W rating, VBR = 7.14–7.88V, VC = 11.2V @ 53.3A | Lower surge capacity; suited for space-constrained PCBs where 1500W is not required | Select SMBJ6.8A only if board layout restricts DO-201 footprint and peak surge energy is ≤600W |
| 1.5SMC6.8A | DO-214AB (SMC) package, 1500W rating, VBR = 6.45–7.14V, VC = 10.5V @ 1000A - identical electrical specs but different package | Same clamping performance; SMC offers higher thermal mass than DO-201 for sustained surge duty | Choose 1.5SMC6.8A when improved thermal dissipation or surface-mount assembly is prioritized over through-hole mounting |
Compared with 1.5KE6.8A R0G, SMBJ6.8A trades surge capacity for smaller footprint, while 1.5SMC6.8A retains full 1500W capability in a thermally superior SMC package - making it a direct functional alternative where mounting method permits.

FAQ
What does the 'R0G' suffix mean in 1.5KE6.8A R0G?
The 'R0G' suffix in 1.5KE6.8A R0G indicates a green, halogen-free compound per IEC 61249-2-21 and RoHS-compliant packaging - confirmed in TSC's ordering information and mechanical data. It does not denote AEC-Q101 qualification (that requires 'H' suffix), but confirms environmental compliance and UL 94V-0 flammability rating for the DO-201 molding compound.
Is 1.5KE6.8A R0G unidirectional or bidirectional?
1.5KE6.8A R0G is unidirectional - explicitly stated in the "Devices for Bipolar Applications" section, which specifies that bidirectional types use 'C' or 'CA' suffixes (e.g., 1.5KE6.8CA). The 'A' in 1.5KE6.8A denotes tighter VBR tolerance (±5%), and the absence of 'C' confirms unidirectional polarity with cathode band marking.
What is the maximum clamping voltage for 1.5KE6.8A R0G at rated surge current?
The maximum clamping voltage for 1.5KE6.8A R0G is 10.5V at 1000A peak pulse current (10/1000μs waveform), as specified in the Electrical Specifications table. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuits during worst-case transient events.
Does 1.5KE6.8A R0G meet ISO 7637-2 immunity requirements?
Yes, 1.5KE6.8A R0G meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements - explicitly listed under FEATURES. Its 1500W surge rating, low clamping voltage, and fast response enable compliance with these automotive transient immunity test pulses when correctly applied in circuit with appropriate layout and grounding.
What is the thermal derating behavior of 1.5KE6.8A R0G above 25°C ambient?
1.5KE6.8A R0G follows the Pulse Derating Curve (Fig.2): peak pulse power decreases linearly above 25°C ambient, reaching ~50% of 1500W at 100°C and zero at 175°C junction temperature. Derating applies to non-repetitive pulses; steady-state power dissipation is limited to 5W at 75°C lead temperature on a 16mm×16mm copper pad.
