Product details
Overview
P6KE110CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a nominal breakdown voltage of 110 V, clamps transients to ≤158 V at 3.9 A peak pulse current, and delivers fast response (<5 ns) with low dynamic impedance. Used in 12 V/24 V vehicle subsystems to protect CAN/LIN transceivers and microcontrollers from EFT and load dump.
For engineers reviewing the P6KE110CAH datasheet, P6KE110CAH pinout, P6KE110CAH application, or P6KE110CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility, bidirectional clamping symmetry, and verified 175 °C junction temperature rating under repetitive surge stress.
Technical Context
The P6KE110CAH implements a planar silicon junction structure optimized for low clamping ratio (VC/VBR ≈ 1.43) and stable avalanche behavior across -55 °C to +175 °C. Its bidirectional configuration enables symmetrical protection on AC lines or floating DC buses without polarity constraints.
It meets IEC 61000-4-4 (EFT) and ISO 7637-2 (automotive load dump) immunity requirements when used with appropriate series impedance. The device's 0.107 %/°C VBR temperature coefficient ensures predictable voltage drift over thermal cycling in under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges typical of automotive load dump or inductive switching |
| Breakdown Voltage VBR (min/max) | 99 V / 121 V - defines reliable avalanche initiation window at 1 mA test current |
| Stand-off Voltage VWM | 89.2 V - maximum continuous reverse voltage before leakage exceeds 1 µA |
| Clamping Voltage VC @ IPP | 158 V @ 3.9 A - peak voltage seen by protected IC during worst-case surge event |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in engine control units and powertrain modules |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.4 g mass and UL 94V-0 molding |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional variants; P6KE110CAH is bidirectional and marked with "P6KE110C" and date code - no polarity designation required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically - bidirectional clamping allows placement without orientation check |
| Leads (tin-plated) | PCB interface & thermal path | Compliant with J-STD-002 solderability; 9.5 mm lead length supports 5 W steady-state dissipation at 75 °C ambient |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR min/max (99–121 V) and VC (158 V) in both directions - eliminates need for polarity-aware layout |
| Low clamping ratio | VC/VBR(max) = 1.43 - minimizes overvoltage stress on downstream 130 V-rated components |
| AEC-Q101 qualification | Validated per stress test conditions for automotive electronics - enables use in ASIL-B systems with proper system-level analysis |
| Fast transient response | <5 ns response time - captures sub-microsecond EFT bursts before sensitive logic is disrupted |
| High surge current capability | 3.9 A peak pulse current (IPP) at 10/1000 µs - withstands repeated ISO 7637-2 Pulse 1/2a/5a events |
Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Lower peak power (600 W same), but SMB package (smaller footprint, lower thermal mass) | Preferred for space-constrained PCBs; requires tighter layout for thermal relief | Select when board area is limited and surge duty cycle is low |
| 1.5KE110CA | Same DO-15 package, higher peak power (1500 W), slower response (~10 ns) | Better for infrequent high-energy events (e.g., lightning); less suitable for fast EFT | Select when primary threat is long-duration load dump, not fast transients |
Compared with SMBJ110CA and 1.5KE110CA, the P6KE110CAH offers balanced performance: AEC-Q101 qualification and DO-15 mechanical robustness make it optimal for automotive harness-mounted protection, while its 5 ns response outperforms 1.5KE110CA in EFT-critical systems.

FAQ
What does the 'CA' suffix indicate in P6KE110CAH?
The 'CA' suffix in P6KE110CAH denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions, unlike unidirectional 'A' variants. This makes P6KE110CAH ideal for AC-coupled lines or floating DC rails where polarity is undefined. The 'H' suffix confirms AEC-Q101 qualification, verified per automotive reliability standards.
How does P6KE110CAH compare to P6KE110A in terms of clamping performance?
P6KE110CAH has identical electrical specs to P6KE110A (VBR: 99–121 V, VC: 158 V @ 3.9 A) but differs in configuration: P6KE110CAH is bidirectional, while P6KE110A is unidirectional. That means P6KE110CAH clamps equally in both directions, whereas P6KE110A only clamps in reverse - requiring correct orientation during placement. Both share the same DO-15 package and AEC-Q101 qualification.
Can P6KE110CAH be used in place of P6KE100CAH for higher-voltage margin?
No - substituting P6KE110CAH for P6KE100CAH increases the stand-off voltage from 81.0 V to 89.2 V and raises clamping to 158 V from 144 V. This may leave 100 V-rated circuits unprotected during surges. P6KE110CAH is not a drop-in replacement; selection must match system VWM and VC limits. Always verify coordination with upstream fuses and downstream IC voltage ratings before substitution.
What is the maximum allowable surge repetition rate for P6KE110CAH?
P6KE110CAH is rated for non-repetitive surges per the 10/1000 µs waveform. For repetitive operation, derating per Figure 2 in the datasheet applies: at 25 °C ambient, peak pulse power drops to ~300 W at 1 Hz, and further at higher frequencies. Sustained repetition requires thermal modeling of PCB copper area and airflow - P6KE110CAH is not intended for continuous switching or high-duty-cycle clamping.
Is P6KE110CAH compliant with RoHS and halogen-free standards?
Yes - P6KE110CAH is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are confirmed in the official Taiwan Semiconductor P2203 datasheet revision and apply specifically to the P6KE110CAH ordering variant.
