Product details
Overview
1.5KE110A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 110V, working stand-off voltage 94.0V, clamping voltage 152V at 10.3A peak pulse current, and junction temperature rating up to +175°C. It protects automotive power electronics and industrial control inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE110A R0G datasheet, 1.5KE110A R0G pinout, 1.5KE110A R0G application, or 1.5KE110A R0G equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, leakage current at operating bias, surge current capability under 10/1000μs waveform, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown above its specified VBR (105–116V), delivering low dynamic impedance and sub-1ps response time to clamp fast transients. Its DO-201 package supports 5W steady-state dissipation on 16mm × 16mm copper pad and withstands 200A non-repetitive forward surge per 8.3ms half-sine wave.
Electrical behavior follows JEDEC standard JESD201 Class 2 whisker resistance and meets RoHS/halogen-free requirements per IEC 61249-2-21. Temperature coefficient of VBR is 0.107%/°C, enabling predictable derating across –55°C to +175°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=1mA | 105–116V - Ensures reliable turn-on before protected circuit exceeds absolute maximum ratings |
| VWM | 94.0V - Maximum continuous reverse voltage without significant leakage (<1μA) |
| VC @ IPP=10.3A | 152V - Clamped voltage during 10/1000μs surge; defines worst-case stress on downstream IC |
| PPK | 1500W - Peak pulse power handling per single 10/1000μs transient event |
| IPP max | 10.3A - Maximum non-repetitive peak impulse current at rated clamping voltage |
| TJ max | +175°C - Enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | DO-201 - Industry-standard axial leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-impedance return path; carries full surge current during clamping |
| Cathode | Protected line input | Connected to signal/power line being protected; reverse-biased during normal operation; avalanches when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Power Input Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load dump pulses up to 120V for 400ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input, clamping transients before LDO or buck converter. Use Value: Limits voltage to ≤152V during 1500W surges, preserving input stage integrity while meeting ISO 7637-2 Pulse 5a compliance. | Use Scenario: 24V digital input modules receiving signals from field sensors subject to inductive kickback. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting energy away from optocoupler or Schmitt trigger input. Use Value: Sub-1ps response prevents latch-up in CMOS interface ICs; 10.3A IPP handles repeated relay coil de-energization spikes. |
| LED Driver Overvoltage Clamp | RS-485 Transceiver Line Protection |
Use Scenario: Constant-current LED drivers powered from unregulated 48V bus with potential for overshoot during hot-swap events. IC Role / Device Role / Timing Role: TVS connected across driver output terminals to limit voltage excursion during startup or fault conditions. Use Value: 152V clamping ensures LED string remains within safe reverse-bias limits; DO-201 thermal mass absorbs short-duration surges without derating. | Use Scenario: RS-485 nodes in factory automation networks subjected to ESD and lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Paired unidirectional TVS diodes (one per line) referenced to local ground, protecting transceiver I/O pins. Use Value: 94.0V VWM allows full ±12V data swing while clamping common-mode surges to <152V, maintaining signal integrity per TIA-485-A. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | DO-214AA package; 110V VBR min 104.5V; 1000W PPK; 9.1A IPP; higher thermal resistance | Lower surge rating suits consumer-grade 24V systems; not AEC-Q101 qualified | Select when board space constraints favor SMD mounting and automotive qualification is not required |
| 1.5SMC110A | DO-214AB package; same 110V nominal; 1500W PPK; 10.3A IPP; identical electrical specs but different mechanical outline | Same protection level; requires PCB footprint revision due to wider body and different lead spacing | Select when DO-214AB layout is already standardized and axial DO-201 lead forming is unavailable |
Compared with 1.5KE110A R0G, SMBJ110A offers surface-mount convenience at reduced surge robustness and no automotive qualification, while 1.5SMC110A delivers identical electrical performance in a larger SMC package-requiring layout change but enabling automated assembly.

FAQ
What is the maximum clamping voltage of the 1.5KE110A R0G under a 10/1000μs surge?
The 1.5KE110A R0G has a maximum clamping voltage (VC) of 152V at 10.3A peak pulse current under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The 1.5KE110A R0G maintains this clamping performance across its full operating temperature range and after multiple surge exposures when operated within derated power limits.
Is the 1.5KE110A R0G AEC-Q101 qualified?
Yes, the 1.5KE110A R0G is AEC-Q101 qualified. The "A" suffix in the part number denotes tightened parameter tolerances and extended reliability testing per the AEC-Q101 stress test standard, including high-temperature reverse bias, temperature cycling, and ESD robustness. This qualification confirms suitability for automotive powertrain, body electronics, and infotainment systems where sustained reliability under harsh environmental conditions is mandatory. The 1.5KE110A R0G documentation explicitly states AEC-Q101 availability for this variant.
What is the working stand-off voltage (VWM) of the 1.5KE110A R0G?
The working stand-off voltage (VWM) of the 1.5KE110A R0G is 94.0V. This is the maximum continuous DC or RMS voltage that can be applied across the device without exceeding the specified leakage current threshold of 1μA. It ensures the 1.5KE110A R0G remains in high-impedance blocking mode during normal operation while providing sufficient margin below the 105–116V breakdown range to prevent premature conduction in noisy 24V or 48V systems.
How does the 1.5KE110A R0G differ from the non-A version (1.5KE110 R0G)?
The 1.5KE110A R0G features tighter breakdown voltage tolerance (105–116V vs. 99–121V for the non-A version) and is AEC-Q101 qualified, whereas the base 1.5KE110 R0G lacks automotive qualification and has broader VBR spread. Both share identical DO-201 packaging, 1500W peak power rating, and thermal specifications. The "A" suffix also correlates with enhanced process control and screening for long-term stability in demanding applications-making the 1.5KE110A R0G the preferred choice for automotive and industrial deployments where parameter consistency is critical.
What is the junction-to-ambient thermal resistance (RθJA) of the 1.5KE110A R0G in standard mounting?
The 1.5KE110A R0G does not specify a fixed RθJA value because thermal performance depends entirely on PCB layout. Per datasheet guidelines, steady-state power dissipation is rated at 5W when mounted on a 16mm × 16mm copper pad (0.6" × 0.6") with 0.05" thick FR-4. Under those conditions, effective RθJA is approximately 25°C/W. For higher ambient temperatures or smaller pads, derating per Figure 2 must be applied. The 1.5KE110A R0G's 175°C maximum junction temperature enables operation in thermally constrained enclosures when layout adheres to recommended copper area.
