Product details
Overview
1V5KE10CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge protection in power and signal lines. It features a 1500W peak pulse power rating at 1.0ms, 14.5V clamping voltage at 10A peak pulse current, and a 9.5–10.5V breakdown voltage range at 1mA test current. It protects sensitive ICs against ESD, lightning-induced transients, and inductive switching spikes in industrial control systems.
For engineers reviewing the 1V5KE10CA datasheet, 1V5KE10CA pinout, 1V5KE10CA application, or 1V5KE10CA equivalent, key selection criteria include clamping voltage vs. protected circuit's absolute maximum rating, standoff voltage margin relative to operating DC bias, unidirectional/bidirectional configuration match, and DO-201 thermal derating behavior under repeated surge conditions.
Technical Context
The 1V5KE10CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response time (<1ns) and low incremental surge resistance. Its bidirectional construction allows symmetrical clamping in AC-coupled or floating signal paths without polarity concerns.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity standards when applied per layout guidelines. The device sustains 10A peak pulse current at 10/1000μs waveform while maintaining ≤14.5V clamping voltage, ensuring downstream ICs remain below their 16V absolute maximum rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 9.5V / 10.5V at 1mA - defines minimum voltage at which avalanche conduction begins; ensures reliable turn-on before protected circuit exceeds safe operating limits |
| VRWM | 8.55V - maximum continuous reverse working voltage; must exceed system's highest steady-state DC bias to prevent leakage or premature conduction |
| VC @ IPPM | 14.5V at 10A - clamping voltage during 10/1000μs surge; determines worst-case overvoltage seen by downstream components |
| PPPM | 1500W at 1ms - peak pulse power handling capacity; supports single-event lightning surges up to 1500W without failure |
| IR @ VRWM | <5μA - reverse leakage current at 8.55V; negligible power loss and no measurable loading on low-power sensor or analog circuits |
| TJ max | 175°C - maximum junction temperature; enables operation in high-ambient environments such as motor drives or outdoor power supplies |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with pure tin-plated leads, UL 94V-0 molding compound, and cathode band marking for unidirectional variants. For 1V5KE10CA (bidirectional), polarity marking is not functional but retained for mechanical consistency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Surge current entry point (either direction) | Acts as cathode during positive transients; serves as anode during negative transients - symmetric conduction path |
| Cathode (Lead 2) | Surge current exit point (either direction) | Acts as anode during positive transients; serves as cathode during negative transients - bidirectional clamping node |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable avalanche characteristics over lifetime and prevents moisture-induced degradation in humid environments |
| 1500W peak pulse power (1ms) | Supports IEC 61000-4-5 Level 4 (4kV line-to-line, 2Ω source impedance) without degradation |
| Clamping ratio VC/VBR ≈ 1.45 | Indicates low dynamic impedance - critical for limiting voltage overshoot during fast-rising transients |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and JESD201 Class 2 whisker resistance - suitable for automotive and industrial PCB assembly |
Applications
| Industrial Motor Drives | AC Power Input Protection |
|---|---|
Use Scenario: Protecting gate drivers and feedback sensors from inductive kickback during IGBT/MOSFET switching in variable-frequency drives. IC Role / Device Role / Timing Role: Bidirectional TVS placed across DC bus or phase outputs to clamp voltage spikes exceeding 12V rail. Use Value: Limits transient overvoltage to ≤14.5V, preventing latch-up or oxide breakdown in isolated gate drivers rated for 16V absolute max. | Use Scenario: Surge suppression on AC mains input of industrial power supplies prior to bridge rectifier. IC Role / Device Role / Timing Role: Primary-level TVS connected line-to-neutral to absorb 10/1000μs surges from utility grid switching or nearby lightning strikes. Use Value: Withstands 1500W pulses while holding clamped voltage below 15V - sufficient to protect MOV-based secondary-stage clamping networks. |
| RS-485 Communication Lines | Automotive Body Control Modules |
Use Scenario: Protecting differential RS-485 transceivers (e.g., MAX1487) against ESD and cable discharge events in factory automation networks. IC Role / Device Role / Timing Role: Bidirectional TVS placed across A/B data lines to provide symmetrical clamping without affecting DC bias or common-mode range. Use Value: Sub-1ns response time and 14.5V clamping ensure transceiver inputs never exceed 16V, preserving ±7V common-mode tolerance and avoiding false logic states. | Use Scenario: Safeguarding LIN bus nodes and microcontroller I/O pins in door module ECUs exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Secondary-level TVS on 12V supply rail feeding LIN transceivers and local sensors. Use Value: 8.55V VRWM provides 15% margin above nominal 12V battery, while 14.5V clamping avoids triggering internal LDO overvoltage shutdown during 24V jump-start events. |

FAQ
What is the breakdown voltage tolerance of the 1V5KE10CA?
The 1V5KE10CA has a specified breakdown voltage range of 9.5V to 10.5V at 1mA test current, representing a ±5% tolerance around the nominal 10V rating. This tight tolerance ensures predictable clamping onset across production lots and simplifies design margining for circuits with strict overvoltage thresholds. The 1V5KE10CA maintains this specification across its full operating temperature range of –55°C to +175°C.
Is the 1V5KE10CA unidirectional or bidirectional?
The 1V5KE10CA is a bidirectional TVS diode, indicated by the "CA" suffix in its part number. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled signal lines, floating power rails, and differential interfaces like RS-485. Unlike unidirectional variants (e.g., 1V5KE10A), the 1V5KE10CA does not require polarity-aware placement on the PCB.
What is the maximum clamping voltage of the 1V5KE10CA under surge conditions?
The maximum clamping voltage of the 1V5KE10CA is 14.5V at 10A peak pulse current with a 10/1000μs waveform. This value is guaranteed per the manufacturer's electrical specifications and represents the worst-case voltage imposed on protected circuitry during standardized surge testing. The 1V5KE10CA achieves this performance with low dynamic impedance, ensuring consistent clamping even under varying surge amplitudes.
Can the 1V5KE10CA be used in surface-mount designs?
No, the 1V5KE10CA is packaged exclusively in the axial-leaded DO-201 through-hole case and is not compatible with surface-mount assembly processes. For SMT alternatives, consider the SMBJ10CA (DO-214AA) or SMCJ10CA (DO-214AB), which share similar voltage ratings but differ in power handling and package footprint. The 1V5KE10CA requires wave soldering or hand-soldering in through-hole layouts.
Does the 1V5KE10CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE10CA is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants, and its pure tin-plated leads satisfy J-STD-002 solderability requirements. These certifications make the 1V5KE10CA suitable for use in environmentally regulated markets including EU industrial equipment and automotive supply chains.
