Product details
Overview
1.5KE110CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 94.0V reverse standoff voltage, 105.0V minimum breakdown voltage, 152.0V maximum clamping voltage at 9.9A peak pulse current, and operates across –55°C to +175°C. It is used in automotive body control modules to protect LIN bus transceivers from ISO 7637-2 pulse 1/2a surges.
For engineers reviewing the 1.5KE110CA-T datasheet, 1.5KE110CA-T pinout, 1.5KE110CA-T application, or 1.5KE110CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under 1.0ms 8/20μs waveform, temperature coefficient of breakdown voltage (0.107%/°C), and DO-201 axial package compatibility with manual or wave-solder assembly.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast sub-nanosecond response time and stable clamping performance under repetitive surge stress. Its symmetrical I-V characteristic enables suppression of both positive and negative transients without polarity sensitivity.
The device is rated for 1500W peak pulse power (tP = 1.0ms, 10/1000μs waveform), 5.0W steady-state dissipation at 75°C lead temperature, and withstands 200A non-repetitive forward surge current. Its ±0.107%/°C VBR tempco ensures predictable clamping shift across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms pulse - sustains high-energy transients like ISO 7637-2 pulse 5a without degradation |
| Reverse Standoff Voltage | 94.0V - maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage |
| Breakdown Voltage | 105.0V min / 116.0V max @ 1.0mA - defines onset of avalanche conduction; tight 10.5% tolerance enables precise protection thresholding |
| Clamping Voltage | 152.0V @ 9.9A - maximum voltage seen by downstream circuit during specified 8/20μs surge; determines safe margin for 12V system ICs |
| Leakage Current | 5.0μA @ 94.0V - minimal standby power loss and negligible loading on low-current sensor or communication lines |
| Operating Temperature | –55°C to +175°C - supports under-hood automotive placement and industrial environments without derating |
| Package | DO-201 axial - industry-standard through-hole package with 9.5mm lead length; compatible with legacy PCB layouts and wave soldering |
Pinout & Package
1.5KE110CA-T is housed in a DO-201 package: axial-leaded, transfer-molded epoxy body (UL 94V-0), 1.12g weight, with unmarked bidirectional terminals. No polarity marking is applied per specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity; no orientation required during placement |
| Lead 1 | Current path input | Accepts surge current from protected line; connects directly to PCB trace requiring protection |
| Lead 2 | Current path return | Routes clamped current to ground or reference rail; must be routed with low-inductance path to maintain clamping integrity |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable, repeatable avalanche characteristics and long-term reliability under thermal cycling and humidity exposure |
| Bidirectional configuration | Protects AC-coupled or differential signals (e.g., CAN, LIN) without external polarity management or dual-device placement |
| 1500W peak pulse rating | Meets ISO 7637-2 Level IV (500W) and IEC 61000-4-5 Line-to-Line (1kV/42Ω) test requirements with design margin |
| RoHS-compliant, halogen-free finish | Complies with automotive ELV directive and IPC-1752A material declaration requirements for Tier 1 supply chain reporting |
| –55°C to +175°C operation | Validated for engine compartment mounting without heatsinking or derating; eliminates need for secondary thermal management |
Applications
| Automotive Power Distribution | Industrial Sensor Interface |

FAQ
What is the difference between 1.5KE110A and 1.5KE110CA-T?
The "C" suffix indicates bidirectional construction: 1.5KE110CA-T clamps both positive and negative transients symmetrically, while 1.5KE110A is unidirectional and requires correct cathode orientation. Both share identical 1500W rating, DO-201 package, and 152V clamping voltage at 9.9A, but only the CA version supports AC or differential signal protection without polarity constraints.
Can 1.5KE110CA-T be used in place of SMAJ110CA?
No - SMAJ110CA is an SMD DO-214AC package with 1.5kW rating but lower 110V standoff and different thermal profile. 1.5KE110CA-T has higher 94V VRWM, larger DO-201 case, and 9.5mm lead length optimized for through-hole wave soldering. Substitution would require PCB layout change and thermal revalidation due to differing junction-to-ambient resistance.
Is 1.5KE110CA-T qualified to AEC-Q101?
No - the datasheet states AEC-Q101 qualification requires specific change control and PPAP capability, and users must contact Diodes directly to request automotive-qualified versions. Standard 1.5KE110CA-T is not AEC-Q101 certified and lacks the required test reports, lot traceability, and manufacturing controls for automotive safety-critical applications.
What is the maximum allowable PCB trace length between 1.5KE110CA-T and protected IC?
To maintain effective clamping, the combined trace inductance from TVS anode/cathode to protected node and ground return must remain below 10nH. For typical FR-4, this limits total trace length to ≤15mm per path when using 10-mil traces and solid ground plane - longer runs degrade clamping performance by increasing voltage overshoot during fast transients.
