Product details
Overview
P6KE110-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 105 V minimum breakdown voltage (VBR), 94.0 V maximum standoff voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the P6KE110-E3/54 datasheet, P6KE110-E3/54 pinout, P6KE110-E3/54 application, or P6KE110-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, unidirectional polarity with cathode band marking, DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE110-E3/54 implements an avalanche breakdown mechanism in a glass-passivated silicon junction, delivering sub-nanosecond response to transient overvoltages. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Thermal design relies on low junction-to-lead thermal resistance (20 °C/W) and 5.0 W steady-state power dissipation capability at TL = 75 °C. The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 0.107 %/°C temperature coefficient of VBR, ensuring predictable voltage margin shift across operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 94.0 V maximum - defines highest continuous DC or RMS voltage the device blocks without leakage exceeding 1.0 µA |
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - ensures reliable avalanche initiation within specified tolerance band |
| VC @ IPPM | 152 V at 3.9 A (10/1000 µs) - maximum clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity under standard 10/1000 µs waveform, duty cycle ≤ 0.01 % |
| RθJL | 20 °C/W - enables thermal management via PCB copper pour or lead-frame heatsinking for sustained surge handling |
| TJ max. | +175 °C - supports operation in under-hood automotive environments and high-temperature industrial enclosures |
| Leakage ID | ≤ 1.0 µA at VWM - minimizes standby power loss and avoids false triggering in high-impedance sensing nodes |
Pinout & Package

Use Scenario: 24 V DC supply to BLDC motor driver IC in smart washing machine, subject to inductive kickback from relay switching. IC Role / Device Role / Timing Role: Unidirectional suppressor mounted across motor driver VDD and ground, triggered only during positive overvoltage events. Use Value: Limits voltage excursion to 152 V during 100 A inductive turn-off, preventing gate oxide rupture in integrated MOSFET drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same VWM (94 V) and VC (152 V), but SMC (DO-214AB) package - 50 % smaller footprint, higher thermal resistance (RθJA = 110 °C/W vs. 75 °C/W) | Better suited for space-constrained PCBs; less effective for repeated surge events due to lower thermal mass | Select SMBJ110A when board area is critical and surge duty cycle is low; verify thermal derating in enclosure airflow conditions. |
| 1.5KE110A | Same electrical specs (VWM, VBR, VC, PPPM) but larger DO-201AD package - higher IFSM (200 A vs. 100 A), RθJL = 10 °C/W | Preferred for high-reliability industrial systems requiring extended surge endurance and lower thermal impedance | Choose 1.5KE110A for mission-critical 24/7 equipment where thermal margin and surge repetition rate exceed P6KE110-E3/54 limits. |
Compared with SMBJ110A and 1.5KE110A, the P6KE110-E3/54 delivers optimal balance of cost, proven AEC-Q101 qualification, and DO-15 through-hole manufacturability - making it preferred for automotive Tier 2 suppliers and industrial OEMs requiring traceable sourcing and legacy process compatibility.

FAQ
What is the maximum clamping voltage of the P6KE110-E3/54 under standard surge conditions?
The P6KE110-E3/54 has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs waveform peak pulse current of 3.9 A. This value is measured per JEDEC standards and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KE110-E3/54 suitable for automotive applications?
Yes, the P6KE110-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision 18-Sep-12, confirming its suitability for automotive powertrain and body electronics. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and validated surge performance make it appropriate for under-hood and cabin-mounted ECUs using the E3 suffix variant.
How does the P6KE110-E3/54 differ from bi-directional TVS diodes like P6KE110CA?
The P6KE110-E3/54 is unidirectional and features a cathode band marking; it blocks reverse voltage up to 94 V and clamps only positive transients. In contrast, P6KE110CA is bi-directional with no polarity marking and clamps transients of either polarity - making P6KE110-E3/54 ideal for DC-biased rails where reverse conduction must be avoided, while P6KE110CA suits AC or floating signal lines.
What is the thermal resistance from junction to ambient for the P6KE110-E3/54?
The P6KE110-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard test conditions (free air, 25 °C ambient). This value assumes minimal PCB copper; actual thermal performance improves significantly with ≥ 1 in² of 2 oz copper connected to both leads, lowering effective RθJA to ~45 °C/W in production layouts.
Can the P6KE110-E3/54 be used in place of the older P6KE110A part?
Yes, the P6KE110-E3/54 is a direct replacement for P6KE110A, maintaining identical electrical specifications (VWM, VBR, VC, PPPM) and DO-204AC packaging. The "E3/54" suffix denotes RoHS compliance, JESD 201 Class 1A whisker resistance, and packaging in 13″ paper tape and reel (4000 pcs/reel) - with no functional or mechanical differences affecting circuit design or layout.
