Product details
Overview
1.5KE110CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 110 V, clamping voltage 158 V at 9.9 A peak pulse current, and working stand-off voltage 89.2 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE110CA R0G datasheet, 1.5KE110CA R0G pinout, 1.5KE110CA R0G application, or 1.5KE110CA R0G equivalent, this part delivers verified AEC-Q101 qualification, sub-1 ns response to ESD events, <1 µA leakage above 10 V, and 175°C junction temperature rating for under-hood and high-reliability embedded systems.
Technical Context
The 1.5KE110CA R0G is a bipolar (bidirectional) TVS diode designed for symmetric transient suppression across AC lines or ungrounded DC buses. Its silicon avalanche structure provides low dynamic impedance and stable clamping over 10/1000 µs surge waveforms.
It meets ISO 7637-2 immunity requirements for automotive electronics and supports steady-state power dissipation of 5 W at 75°C lead temperature. The device operates from −55°C to +175°C and features pure tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 99 V / 121 V at 1.0 mA test current - defines reliable avalanche onset window for predictable clamping behavior |
| VWM | 89.2 V - maximum continuous operating voltage before significant leakage begins |
| VC @ IPP | 158 V at 9.9 A peak pulse current - clamping voltage limiting downstream circuit stress during 10/1000 µs surges |
| PPK | 1500 W - peak surge power handling capability per JEDEC standard waveform |
| IR @ VWM | <1 µA - minimal leakage ensures negligible standby power loss in high-impedance sensing or battery-backed circuits |
| TJ max | +175°C - enables placement near heat sources (e.g., power converters, motor drivers) without derating |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and JESD201 Class 2 whisker resistance |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional variants; for bidirectional 1.5KE110CA R0G, polarity is non-directional - terminals are interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (reversible) | Bidirectional avalanche junction | Both terminals function identically - no polarity sensitivity; connects across protected line-to-line or line-to-ground |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads serve as low-inductance paths to shunt transient energy directly to ground or return rail; tin-plated for reliable solder joint formation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| 10/1000 µs surge rating | 1500 W peak power handling per standardized lightning/inductive-switching transient waveform |
| ISO 7637-2 compliance | Tested against Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) |
| Fast response time | <5 ns turn-on - ensures clamping activation before sensitive ICs experience overvoltage damage |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | 600 W rating, SMC package, lower clamping voltage (187 V @ 3.2 A), 150 °C TJ max | Lower surge capacity suits space-constrained PCBs with moderate threat levels (IEC 61000-4-5 Level 3) | Select when board area is limited and peak surge energy is ≤600 W; not suitable for ISO 7637-2 Pulse 5a load dump |
| 1.5SMC110CA | Same 1500 W rating, SMC package, identical VBR/VC, but rated only to 150 °C junction temperature | Lacks AEC-Q101 qualification and ISO 7637-2 validation; intended for commercial/industrial use only | Choose for cost-sensitive industrial designs where automotive qualification and extended temperature operation are not required |
Compared with SMBJ110CA and 1.5SMC110CA, the 1.5KE110CA R0G uniquely combines 1500 W surge capability, AEC-Q101 qualification, ISO 7637-2 compliance, and +175°C operation - making it the only option qualified for under-hood automotive power rail protection without thermal derating.

FAQ
What does the 'CA' suffix mean in 1.5KE110CA R0G?
The 'CA' suffix in 1.5KE110CA R0G indicates a bidirectional configuration - meaning the device functions identically in both polarities and has no anode/cathode orientation requirement. This differs from unidirectional 'C' versions, which require correct polarity placement. The 1.5KE110CA R0G is therefore ideal for AC-coupled or floating DC bus protection where polarity cannot be guaranteed.
Is 1.5KE110CA R0G AEC-Q101 qualified?
Yes, 1.5KE110CA R0G is AEC-Q101 qualified. The 'R0G' ordering code denotes RoHS-compliant, green compound packaging and confirms qualification per AEC-Q101 Rev D for stress tests including temperature cycling, highly accelerated life testing (HALT), and mechanical shock. This makes 1.5KE110CA R0G suitable for automotive powertrain and body electronics applications.
What is the clamping voltage of 1.5KE110CA R0G at its rated surge current?
The clamping voltage of 1.5KE110CA R0G is 158 V at 9.9 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the maximum voltage seen downstream during a full-rated surge event - a critical parameter for ensuring protected ICs remain within absolute maximum ratings.
Can 1.5KE110CA R0G replace 1.5KE110A in a design?
No, 1.5KE110CA R0G cannot directly replace 1.5KE110A because they differ fundamentally in configuration: 1.5KE110A is unidirectional (anode/cathode), while 1.5KE110CA R0G is bidirectional. Substituting without verifying circuit topology may result in improper clamping or failure to protect reverse-polarity transients. Always validate polarity requirements and surge directionality before interchange.
What is the maximum junction temperature rating for 1.5KE110CA R0G?
The maximum junction temperature rating for 1.5KE110CA R0G is +175°C, as specified in the Absolute Maximum Ratings table. This allows operation in high-temperature environments such as engine compartments or enclosed industrial enclosures without thermal derating - a key advantage over alternatives rated only to +150°C.
