Product details
Overview
P6KE110CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 110 V, clamps transients to ≤152 V at 4.1 A peak surge current, and delivers fast response (<5 ns) with low dynamic impedance. It is used in automotive body electronics, industrial I/O modules, and AC/DC power supply input stages to absorb EFT and lightning-induced surges.
For engineers reviewing the P6KE110CA datasheet, P6KE110CA pinout, P6KE110CA application, or P6KE110CA equivalent, key selection criteria include its bidirectional DO-15 package, 89.2 V standoff voltage, <1 μA leakage at rated VWM, 152 V clamping voltage at 4.1 A, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE110CA operates as a silicon avalanche diode configured in a symmetrical bipolar structure, enabling identical clamping behavior in both forward and reverse directions. Its junction design supports 600 W non-repetitive peak pulse power per the 10/1000 µs waveform standard (IEC 61000-4-5), with thermal derating above 25 °C per Fig.2.
It exhibits a temperature coefficient of VBR at +0.107 %/°C and maintains stable clamping performance across –55 °C to +175 °C junction temperature range. The device uses pure tin-plated leads compliant with J-STD-002 and meets UL 94V-0 flammability rating in its DO-204AC molded case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10/1000 µs surge events without failure, critical for lightning/EFT immunity |
| Standoff Voltage VWM | 89.2 V - Maximum continuous DC or RMS voltage before significant leakage; sets operating margin below 110 V nominal |
| Breakdown Voltage VBR | 105–116 V @ 1 mA - Confirmed avalanche initiation range; ensures reliable turn-on during overvoltage |
| Clamping Voltage VC | 152 V @ 4.1 A - Maximum voltage seen by protected circuit during full-rated surge; defines protection window |
| Leakage Current ID | <1 µA @ 89.2 V - Negligible standby power loss and minimal loading on upstream sources |
| Junction Temperature Range | –55 °C to +175 °C - Enables deployment in under-hood automotive and high-temp industrial environments |
| Response Time | <5 ns - Limits voltage overshoot during fast transients such as ESD and EFT bursts |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional variants; P6KE110CA is bidirectional and marked without polarity band per manufacturer specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional polarity - either lead connects to protected line or ground; enables flexible placement in AC or floating circuits |
| Lead 1 / Lead 2 | Current-carrying terminals | Both leads conduct surge current equally in either direction; require ≥9.5 mm lead length for rated 5 W steady-state dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and infotainment power rails |
| 600 W surge capability | Withstands IEC 61000-4-5 Level 3 (1 kV/2 kV) surge tests without degradation |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes stress on downstream ICs by tightly constraining overvoltage excursion |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
| UL Recognized (E326243) | Approved for use in end equipment requiring UL safety certification |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power pins from load dump and alternator ripple in vehicle door modules. IC Role / Device Role / Timing Role: Bidirectional TVS placed between 12 V rail and chassis ground to clamp ±100 V transients within 5 ns. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V logic ICs by limiting rail voltage to ≤152 V during 600 W surge events. |
Use Scenario: Shields 24 V DC digital input circuitry from inductive kickback when switching solenoids or relays. IC Role / Device Role / Timing Role: Mounted across input terminals to shunt flyback energy before it reaches optocoupler or MCU input stage. Use Value: Ensures >100,000 switching cycles without degradation, thanks to low dynamic impedance and 175 °C max junction rating. |
| AC/DC Power Supply Input Stage | Smart Lighting Driver EMI Filter |
Use Scenario: Installed across primary-side rectifier output to suppress line-to-line surges entering offline SMPS. IC Role / Device Role / Timing Role: Fast-acting clamp that activates before MOVs reach full conduction, reducing stress on bulk capacitor and controller IC. Use Value: Extends system lifetime by absorbing repetitive 10/1000 µs surges up to 600 W without parameter drift. |
Use Scenario: Integrated into LED driver PCB near bridge rectifier to suppress conducted EMI from dimmer switching noise. IC Role / Device Role / Timing Role: Bidirectional suppression element referenced to isolated DC bus, handling both positive and negative half-cycle spikes. Use Value: Maintains Class B EMC compliance by limiting differential-mode transients to <152 V, preventing false triggering of current sense circuitry. |
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 (Bourns) | Same 110 V nominal, 600 W rating, but SMB package (surface-mount); lower clamping voltage (150 V @ 4.2 A) | Requires PCB rework for SMT layout; better thermal performance in compact designs | Select when board space is constrained and automated assembly is preferred |
| 1.5KE110CA (ON Semiconductor) | Same DO-15 package and 110 V rating, but 1.5 kW peak power (10/1000 µs); higher clamping (170 V @ 8.8 A) | Over-spec'd for 600 W needs; may mask marginal surge events due to higher VC | Select only if legacy 1.5KE footprint compatibility is required and higher clamping is acceptable |
Compared with SMBJ110CA and 1.5KE110CA, the P6KE110CA offers optimal balance of through-hole manufacturability, 600 W surge headroom, and tight 152 V clamping-making it ideal for cost-sensitive, high-reliability industrial and automotive power rail protection where DO-15 form factor is standardized.

FAQ
What does the 'CA' suffix indicate in P6KE110CA?
The 'CA' suffix in P6KE110CA denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, unlike unidirectional 'A' variants. This allows direct placement across AC lines or floating DC nodes without polarity concerns, and is confirmed in TSC's P2203 datasheet Section "Devices for Bipolar Applications".
Is P6KE110CA AEC-Q101 qualified?
Yes, P6KE110CA is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of the TSC P2203 datasheet and reinforced in the "ORDERING INFORMATION" table where 'H' suffix indicates AEC-Q101 grade - and P6KE110CA falls within the qualified voltage range (P6KE6.8–P6KE440, excluding only P6KE6V8A–P6KE9V1A).
What is the maximum clamping voltage for P6KE110CA at its rated surge current?
The maximum clamping voltage for P6KE110CA is 152 V at 4.1 A peak pulse current (IPP), measured under the standard 10/1000 µs waveform. This value is specified in the "ELECTRICAL SPECIFICATIONS" table on page 3 of the TSC P2203 datasheet and defines the upper voltage limit imposed on protected circuitry during full-rated surge events.
Can P6KE110CA replace P6KE110A in a design?
No - P6KE110CA and P6KE110A are not interchangeable. P6KE110A is unidirectional (anode/cathode asymmetry), while P6KE110CA is bidirectional (no polarity). Substituting one for the other risks incorrect clamping behavior, especially in AC or floating circuits. The datasheet explicitly separates them in ordering codes and electrical tables.
What is the standoff voltage (VWM) of P6KE110CA, and why does it matter?
The standoff voltage (VWM) of P6KE110CA is 89.2 V - the maximum continuous working voltage the device can block without exceeding 1 µA leakage. This parameter ensures the TVS remains inactive during normal operation while providing sufficient margin below the 110 V nominal breakdown, preventing nuisance conduction in 72–96 V automotive or industrial systems.
