Product details
Overview
1.5KE10CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 10V, working stand-off voltage 8.1V, clamping voltage 15.0V at 10A peak pulse current, and fast response time <5.0ns. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE10CA datasheet, 1.5KE10CA pinout, 1.5KE10CA application, or 1.5KE10CA equivalent, this page delivers verified electrical specs, bidirectional TVS behavior, DO-201 mechanical data, AEC-Q101 qualification status, and real-world surge immunity context for ESD and inductive switching protection.
Technical Context
The 1.5KE10CA operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±10V in both polarities. Its VBR min/max = 9.0V/11.0V at IT = 1.0mA ensures precise turn-on across temperature, while TJ max = +175°C supports under-hood automotive use.
It delivers 1500W peak pulse power (10/1000μs waveform), clamps to ≤15.0V at IPP = 10A, and exhibits low dynamic impedance for effective transient suppression. Leakage current ID ≤1μA at VWM = 8.1V minimizes standby power loss in always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=1mA | 9.0–11.0V: Ensures reliable bidirectional conduction onset within tight tolerance for predictable clamping threshold |
| VWM | 8.1V: Maximum continuous reverse voltage before leakage exceeds 1μA - sets safe operating margin below VBR |
| VC @ IPP=10A | 15.0V: Clamped voltage during 10/1000μs surge - defines worst-case stress on downstream ICs |
| PPK | 1500W: Peak pulse power handling per JEDEC standard - validates robustness against automotive load dump |
| Response Time | <5.0ns (bidirectional): Enables suppression of fast EFT and ESD events before sensitive circuitry is damaged |
| TJ max | +175°C: Junction temperature rating - supports placement near high-power components in engine control units |
| Package | DO-201: Industry-standard axial leaded package with UL 94V-0 molding - enables manual or wave soldering |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; 1.5KE10CA is bidirectional and marked without polarity band. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias (for unidirectional mode) | Bidirectional operation means either terminal serves as anode or cathode depending on transient polarity |
| Cathode | Current exit point in forward bias (for unidirectional mode) | No dedicated cathode marking on 1.5KE10CA - symmetrical terminals enable polarity-agnostic placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) immunity requirements |
| Low dynamic impedance | Enables sharp voltage clamping with minimal overshoot during high-di/dt transients like relay coil de-energization |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive - suitable for green manufacturing and export compliance |
| 1500W surge rating | Handles worst-case 10/1000μs transients without degradation - exceeds typical 12V automotive system requirements |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 12V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Bidirectional TVS placed at power entry to clamp positive and negative spikes before DC-DC converters and microcontrollers. Use Value: Limits rail voltage to ≤15.0V during 10A surge, preventing latch-up or permanent damage to 16V-rated input stages. | Use Scenario: Safeguarding 24V digital input modules in programmable logic controllers against field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Front-end transient suppressor on dry-contact or sensor inputs exposed to factory floor noise. Use Value: Sub-5ns response captures fast EFT bursts (IEC 61000-4-4), while 1500W rating absorbs repeated 40A/50Hz half-sine surges from solenoid switching. |
| LED Driver Surge Suppression | Telecom Line Interface Protection |
Use Scenario: Shielding constant-current LED drivers in street lighting from lightning-induced surges on AC mains or DC bus lines. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output or input to shunt energy away from MOSFETs and current-sense amplifiers. Use Value: Clamping at 15.0V prevents overvoltage failure of 20V-rated gate drivers and maintains luminance stability during grid disturbances. | Use Scenario: Protecting RS-485 transceivers and isolation barriers in building automation networks from induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary-level TVS on isolated power and signal lines after primary gas discharge tube (GDT) stage. Use Value: Low leakage (<1μA at 8.1V) avoids loading bias networks, while bidirectional symmetry matches differential signaling polarity reversals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ10CA | Same DO-214AC (SMA) package; 10V VBR, 1500W PPK, but VC = 17.0V @ 10A - 13% higher clamping voltage | Higher VC reduces margin for 15V-tolerant ICs; requires layout review if replacing 1.5KE10CA in space-constrained designs | Select when SMA footprint is preferred over DO-201 axial leads and higher clamping voltage is acceptable |
| ON Semiconductor 1.5SMC10CA | DO-214AB (SMC) package; identical VBR (9.0–11.0V), VC = 15.0V @ 10A, but rated for 1500W with tighter thermal derating above 75°C | SMC offers higher power density but requires reflow-compatible PCB design; same clamping performance enables drop-in functional replacement | Choose for surface-mount assembly where board space is limited and thermal management uses copper pour |
Compared with SMAJ10CA and 1.5SMC10CA, the 1.5KE10CA provides identical clamping voltage (15.0V) in a through-hole DO-201 package optimized for manual assembly, high-reliability automotive environments, and legacy industrial designs requiring axial leaded components.

FAQ
What does the 'CA' suffix indicate in 1.5KE10CA?
The 'CA' suffix in 1.5KE10CA denotes a bidirectional configuration - meaning the device functions identically in both polarities, with symmetrical breakdown voltage (9.0–11.0V) and clamping behavior. Unlike unidirectional 'A' variants (e.g., 1.5KE10A), the 1.5KE10CA has no cathode marking and is used where transient polarity is unpredictable, such as across AC lines or differential buses.
Is 1.5KE10CA AEC-Q101 qualified?
Yes, 1.5KE10CA is AEC-Q101 qualified when ordered with the 'H' suffix (e.g., 1.5KE10CAH). The base 1.5KE10CA part meets all electrical and mechanical specifications of the AEC-Q101 standard, and Taiwan Semiconductor certifies the DO-201 variant for automotive use under stress test conditions including temperature cycling, high-temperature reverse bias, and ESD.
What is the maximum clamping voltage of 1.5KE10CA at its rated peak pulse current?
The maximum clamping voltage VC of 1.5KE10CA is 15.0V at IPP = 10A for a 10/1000μs waveform. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - critical for ensuring compatibility with 15V-tolerant interface ICs and regulators.
How does 1.5KE10CA compare to 1.5KE10A in terms of circuit application?
The 1.5KE10A is unidirectional with a cathode band and conducts only in reverse bias, making it suitable for DC rail protection where polarity is fixed. In contrast, 1.5KE10CA is bidirectional and symmetrical - ideal for AC-coupled lines, RS-485 buses, or any application where voltage transients may swing positive or negative relative to ground. Their VBR and VC values are identical, but placement and marking differ.
What is the junction-to-ambient thermal resistance (RθJA) for 1.5KE10CA in DO-201 package?
Taiwan Semiconductor does not publish RθJA for 1.5KE10CA in free-air conditions; instead, the datasheet specifies steady-state power dissipation PD = 5W at TL = 75°C with 0.375" (9.5mm) lead length on a 0.6" × 0.6" copper pad. For thermal design, engineers should reference Figure 2 (Pulse Derating Curve) and apply board-level copper area rules rather than assume a fixed RθJA value.
