Product details
Overview
P6KE110CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features a 94.0 V standoff voltage (VWM), 105–116 V breakdown voltage (VBR) at 1 mA, 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the P6KE110CA-E3/54 datasheet, P6KE110CA-E3/54 pinout, P6KE110CA-E3/54 application, or P6KE110CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamping avalanche diode, responding within <1 ps to transient overvoltages and maintaining low dynamic impedance during surge events. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity marking requirements and simplifying PCB layout for AC-coupled or differential signal paths.
The P6KE110CA-E3/54 uses glass-passivated junction technology for stable breakdown characteristics and repeatable surge performance. It is rated for -55 °C to +175 °C operating junction temperature, with thermal derating applied above 25 °C ambient per Figure 2, and supports soldering up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Avalanche conduction initiates within this range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 152 V at IPPM = 3.9 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained for single 10/1000 μs waveform; defines transient energy absorption capacity without failure. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Confirms minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +175 °C - Enables operation in under-hood automotive or high-temperature industrial environments without derating. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements when mounted on PCB copper pour. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional functionality confirmed by CA suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked ends) | Bidirectional avalanche junction terminals | Either lead serves as anode or cathode depending on transient polarity; no orientation required during placement. |
| Leads (both) | Current conduction path and thermal interface | Primary heat dissipation route to PCB copper; RθJL = 20 °C/W assumes 0.375" (9.5 mm) lead length per JEDEC standard. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly routed and decoupled. |
| AEC-Q101 qualified (HE3 variant); E3 is commercial grade | P6KE110CA-E3/54 meets commercial-grade reliability; HE3 variant required for automotive under-hood use. |
| UL 497B recognized (QVGQ2 file E136766) | Validated for telecom and industrial surge protection systems requiring third-party safety certification. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing with 12 V/24 V buses. |
Applications
| Automotive Sensor Protection | Industrial PLC Analog Inputs |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and position sensors from load-dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role: Bidirectional clamping element placed across differential signal pair or supply rail to shunt surge energy to ground.

IC Role / Device Role: Primary overvoltage clamp on input terminals, coordinated with series current-limiting resistors and filtering capacitors. Use Value: Maintains signal integrity below 152 V clamping level while surviving repeated 600 W pulses - enabling >10-year field reliability. |
| Telecom Line Interface | Consumer Appliance Motor Control |
|

IC Role / Device Role: First-stage protector between line transformer secondary and codec IC, absorbing common-mode transients. Use Value: UL 497B recognition confirms suitability for certified telecom equipment; 1.0 μA leakage avoids DC bias shift in analog receive paths. |
Use Scenario: Input rail protection for BLDC motor driver ICs subjected to back-EMF spikes during commutation in washing machines or HVAC fans. IC Role / Device Role: Parallel-connected TVS across 12 V or 24 V DC supply input to suppress repetitive inductive kickback. Use Value: 175 °C max junction temperature allows mounting near hot motor drivers; DO-15 axial form enables through-hole reinforcement on high-current traces. |
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 | DO-214AA (SMB) package; lower RθJA (50 °C/W vs. 75 °C/W); same VWM/VBR/VC ratings. | Surface-mount footprint reduces board space but requires reflow profile validation; less robust for manual repair. | Select SMBJ110CA when automated assembly and space constraints outweigh axial-leaded serviceability needs. |
| 1.5KE110CA | Higher PPPM (1500 W); larger DO-201AD package; identical VWM/VBR/VC specs; higher IFSM (200 A). | Used where legacy 1.5 kW surge standards apply (e.g., older industrial IEC 61000-4-5 test plans); heavier leads limit routing density. | Choose 1.5KE110CA only if system-level testing mandates ≥1 kW surge rating or existing designs mandate DO-201AD footprint. |
Compared with SMBJ110CA and 1.5KE110CA, the P6KE110CA-E3/54 offers optimal balance of cost, DO-15 through-hole manufacturability, and 600 W surge handling for mid-tier industrial and automotive accessory applications - without over-specifying power or sacrificing repairability.

FAQ
What does the "CA" suffix mean in P6KE110CA-E3/54?
The "CA" suffix in P6KE110CA-E3/54 indicates a bidirectional configuration - meaning the device provides symmetrical clamping for positive and negative transients without polarity sensitivity. Unlike unidirectional "A" variants, P6KE110CA-E3/54 has no cathode band marking and functions identically in either orientation, simplifying layout for AC-coupled or differential lines.
Is P6KE110CA-E3/54 AEC-Q101 qualified?
No - P6KE110CA-E3/54 carries the E3 suffix, denoting RoHS-compliant commercial grade. For AEC-Q101 qualification, the correct part is P6KE110CAHE3/54 (HE3 suffix). The HE3 variant undergoes additional stress testing per AEC-Q101 Rev D, including high-temperature operating life and unbiased high-humidity accelerated stress tests.
What is the maximum clamping voltage of P6KE110CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE110CA-E3/54 is 152 V, measured at a peak pulse current (IPPM) of 3.9 A using the standardized 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case surge events and must be compared against the absolute maximum ratings of downstream components.
Can P6KE110CA-E3/54 be used in place of P6KE110A-E3/54?
No - P6KE110CA-E3/54 and P6KE110A-E3/54 are not interchangeable due to fundamental polarity differences. P6KE110A-E3/54 is unidirectional (cathode-marked, conducts only in reverse bias), while P6KE110CA-E3/54 is bidirectional (no marking, clamps both polarities). Substitution risks open-circuit failure or incorrect clamping behavior in DC-biased applications.
What is the thermal resistance from junction to ambient for P6KE110CA-E3/54?
The typical junction-to-ambient thermal resistance (RθJA) of P6KE110CA-E3/54 is 75 °C/W under standard JEDEC test conditions (single device on FR-4 board, 1 in² copper pad). This value increases significantly in compact layouts or still-air environments; for thermal design, junction temperature must stay ≤175 °C using RθJL = 20 °C/W and measured lead temperature.
