Product details
Overview
1V5KE110CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 106–116 V at 1 mA test current, reverse stand-off voltage 94.0 V, clamping voltage 152 V at 9.9 A peak pulse current, and operating junction temperature range of –55°C to +175°C. It protects power rails and I/O lines in industrial motor drives and telecom power supplies against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE110CA datasheet, 1V5KE110CA pinout, 1V5KE110CA application, or 1V5KE110CA equivalent, key selection criteria include bidirectional clamping performance at 10/1000 µs waveform, low incremental surge resistance, sub-1 µA leakage above 10 V, RoHS/halogen-free compliance, and DO-201 mechanical robustness for high-reliability board-level surge protection.
Technical Context
The 1V5KE110CA operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its CA suffix designation. Its 1500 W peak pulse power rating is specified at 1 ms (10/1000 µs standard waveform), and it exhibits fast response time (<1 ns) to transient events.
Electrical behavior follows JEDEC-standard TVS parameters: breakdown voltage tolerance ±5% (106–116 V), clamping voltage of 152 V at 9.9 A IPPM, and thermal limits defined by TJ,max = 175°C with derating starting at 75°C ambient for continuous power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W at 1 ms - sustains single high-energy transients per IEC 61000-4-5 Level 4 without failure |
| Breakdown Voltage VBR | 106–116 V @ 1 mA - defines minimum voltage at which avalanche conduction begins in either direction |
| Reverse Stand-off Voltage VRWM | 94.0 V - maximum DC or continuous AC voltage the device blocks before clamping initiates |
| Clamping Voltage VC | 152 V @ 9.9 A IPPM - maximum voltage seen by protected circuit during full-rated surge event |
| Junction Temperature Range | –55°C to +175°C - supports operation in under-hood automotive, industrial PLC, and outdoor telecom enclosures |
| Leakage Current IR | <1 µA @ 94 V - ensures negligible standby power loss and signal integrity in high-impedance circuits |
| Package | DO-201 - axial-leaded, UL 94V-0 molded case with pure tin-plated leads compliant with J-STD-002 solderability |
Pinout & Package
1V5KE110CA uses the DO-201 axial package with two terminals: cathode-marked end (band) and anode. No polarity marking is used for bidirectional operation; both terminals are functionally symmetric. Leads are 0.375 inch long, rated for 5 W continuous power dissipation at 75°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Surge current entry point (positive transient) | Conducts during positive voltage excursions above VRWM; forms symmetrical path with cathode |
| Cathode (banded end) | Surge current entry point (negative transient) | Conducts during negative voltage excursions; identical clamping behavior ensures bidirectional protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable avalanche characteristics and long-term reliability under repeated surge stress |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving system immunity |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and global environmental directives for industrial and telecom manufacturing |
| Fast response time | <1 ns turn-on - clamps before downstream ICs experience damaging overvoltage |
| JEDEC-standard 10/1000 µs waveform rating | Validated for IEC 61000-4-5 surge immunity testing up to 4 kV line-to-line |

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, DO-214AA package, lower clamping voltage (187 V @ 3.2 A) | Better suited for space-constrained PCBs but requires higher IPPM derating for same energy absorption | Select when board area is limited and surge energy is ≤600 W; verify thermal relief for sustained duty cycles |
| 1N6296A | Same manufacturer, identical specs - direct JEDEC cross-reference for 1V5KE110CA | No functional difference; used interchangeably in legacy designs and BOMs | Preferred for second-source procurement where Taiwan Semiconductor part numbering must be retained |
Compared with SMBJ110CA and 1N6296A, the 1V5KE110CA delivers 2.5× higher peak pulse power in the same voltage class, enabling fewer devices per rail in high-energy environments, while 1N6296A offers identical performance with standardized JEDEC nomenclature for documentation consistency.

FAQ
What is the clamping voltage of the 1V5KE110CA under full-rated surge conditions?
The 1V5KE110CA has a maximum clamping voltage (VC) of 152 V when subjected to its rated peak pulse current of 9.9 A, measured using the standard 10/1000 µs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The 1V5KE110CA maintains this clamping performance consistently across its operational temperature range from –55°C to +175°C.
Is the 1V5KE110CA unidirectional or bidirectional, and how is polarity marked?
The 1V5KE110CA is a bidirectional TVS diode, indicated by the "CA" suffix per manufacturer documentation. Unlike unidirectional variants, it has no functional polarity marking - both terminals behave identically under positive or negative transients. The cathode band present on the DO-201 package is for manufacturing consistency only and does not define electrical polarity for the 1V5KE110CA.
Can the 1V5KE110CA replace the 1N6296A in existing designs?
Yes - the 1V5KE110CA and 1N6296A are JEDEC-registered equivalents with identical electrical specifications, DO-201 packaging, and thermal ratings. Taiwan Semiconductor lists them as interchangeable in official documentation. The 1V5KE110CA may be used as a drop-in replacement for 1N6296A without layout or firmware changes, preserving all surge protection performance.
What is the maximum allowable reverse leakage current for the 1V5KE110CA at its rated VRWM?
At its reverse stand-off voltage (VRWM) of 94.0 V, the 1V5KE110CA exhibits a maximum reverse leakage current (IR) of less than 1 µA at 25°C ambient. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-backed systems. The 1V5KE110CA maintains this specification across its full operating temperature range.
Does the 1V5KE110CA meet industry standards for surge immunity testing?
Yes - the 1V5KE110CA is rated for IEC 61000-4-5 surge immunity testing with a 1500 W peak pulse power capability at the standard 10/1000 µs waveform. Its clamping performance, thermal robustness, and bidirectional symmetry make it suitable for Level 4 (4 kV line-to-line) compliance in industrial and telecom equipment. The 1V5KE110CA's DO-201 package also meets UL 94V-0 flammability requirements.
