Product details
Overview
P4KE110CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 110 V breakdown voltage (VBR min/max = 105–116 V), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage at 2.6 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4KE110CA-E3/54 datasheet, P4KE110CA-E3/54 pinout, P4KE110CA-E3/54 application, or P4KE110CA-E3/54 equivalent, key selection considerations include bidirectional clamping capability, DO-41 leaded package compatibility with through-hole PCB assembly, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for transient power dissipation management.
Technical Context
This device operates as a voltage-clamping protection element that conducts above its breakdown threshold to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance, enabling consistent clamping performance across repetitive transients.
The bidirectional configuration allows symmetric suppression of positive and negative polarity surges without polarity marking on the DO-41 body. It supports 175 °C maximum junction temperature and meets JESD 22-B106 soldering requirements (275 °C, 10 s), making it suitable for reflow and wave-soldered industrial assemblies.
Key Specifications

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 | Surface-mount SMB package (vs. through-hole DO-41); same VBR range (105–116 V), lower PPPM = 600 W | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics | Select when board real estate is limited and automated assembly is preferred over manual through-hole insertion |
| 1.5KE110CA | Higher PPPM = 1500 W; larger DO-201AE package; identical VBR, VWM, and VC specs | Used where higher surge margin is required (e.g., outdoor power supplies), but requires larger footprint and higher cost | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and additional energy absorption is needed |
Compared with SMBJ110CA and 1.5KE110CA, the P4KE110CA-E3/54 delivers optimal balance of proven automotive reliability, through-hole manufacturability, and cost-effective 400 W surge handling - ideal for mid-tier industrial and automotive modules where DO-41 compatibility and AEC-Q101 validation are mandatory.

FAQ
What is the breakdown voltage tolerance of P4KE110CA-E3/54?
The P4KE110CA-E3/54 has a specified breakdown voltage range of 105 V to 116 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 110 V rating. This tight VBR window ensures predictable clamping onset and compatibility with 100 V-rated downstream components. The P4KE110CA-E3/54 maintains this specification across its full operating temperature range.
Is P4KE110CA-E3/54 suitable for automotive applications?
Yes, the P4KE110CA-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and powertrain applications. Its glass-passivated junction and DO-41 construction meet automotive reliability requirements for vibration, thermal cycling, and surge endurance. The P4KE110CA-E3/54 is commonly deployed in engine control units and body electronics for load-dump protection.
What is the maximum clamping voltage of P4KE110CA-E3/54 under surge conditions?
The P4KE110CA-E3/54 exhibits a maximum clamping voltage (VC) of 152 V at 2.6 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during a defined transient event. The P4KE110CA-E3/54 achieves this with a clamping ratio of approximately 1.37, indicating efficient voltage limiting relative to its VBR.
Does P4KE110CA-E3/54 have polarity markings?
No, the P4KE110CA-E3/54 is a bidirectional TVS diode and carries no polarity marking on its DO-41 package body. Its symmetrical structure allows either lead to serve as anode or cathode depending on transient polarity, simplifying PCB layout and eliminating orientation errors during assembly. This distinguishes it from unidirectional variants like P4KE110A, which feature a cathode band.
What is the thermal resistance of P4KE110CA-E3/54?
The P4KE110CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with standard lead length conditions. This parameter is essential for estimating junction temperature rise during repetitive surge events and informs heatsinking decisions in high-duty-cycle applications. The P4KE110CA-E3/54 also specifies RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm), supporting thermal modeling in enclosure designs.
