Product details
Overview
P4KE110CAHE3/54 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 clamping voltage (VC) at 2.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the P4KE110CAHE3/54 datasheet, P4KE110CAHE3/54 pinout, P4KE110CAHE3/54 application, or P4KE110CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and low leakage (<1.0 μA at VWM).
Technical Context
This device operates as a voltage-clamping protection element in bidirectional configurations, responding to both positive and negative transients without polarity dependence. Its glass-passivated junction enables fast response time (<1.0 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Designed for operation across –55 °C to +175 °C junction temperature range, it supports high-reliability automotive applications via AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The DO-41 package provides robust lead-to-lead isolation and UL 94 V-0 flammability compliance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA package; higher 600 W PPPM; lower VC = 177 V @ 2.3 A; surface-mount only | Requires PCB rework for SMT layout; better suited for space-constrained designs with higher surge margin | Select SMBJ110CA when board real estate is limited and 600 W rating is required; not drop-in compatible with P4KE110CAHE3/54 through-hole footprint |
| 1.5KE110CA | DO-201AD package; same 400 W rating; identical VBR/VC specs; larger body (5.6 mm diameter vs. 2.7 mm) | Compatible with high-power industrial rails where lead spacing and thermal mass are prioritized over size | Choose 1.5KE110CA for enhanced thermal dissipation in high-ambient-temperature enclosures; requires wider PCB hole spacing |
Compared with SMBJ110CA and 1.5KE110CA, the P4KE110CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-41 through-hole manufacturability, and proven field reliability in cost-sensitive automotive and industrial assemblies - making it preferred where legacy through-hole assembly and automotive qualification are mandatory.

FAQ
What is the clamping voltage of the P4KE110CAHE3/54 and how does it protect downstream circuits?
The P4KE110CAHE3/54 clamps at 152 V when subjected to its rated 2.6 A peak pulse current (10/1000 μs waveform). This defined VC limits the maximum voltage seen by protected components - such as microcontrollers or transceivers - ensuring they remain below absolute maximum ratings during surge events. Its bidirectional symmetry allows protection of AC-coupled or floating lines without polarity concerns, and the low incremental resistance sustains clamping performance across multiple transients.
Is the P4KE110CAHE3/54 suitable for automotive applications?
Yes, the P4KE110CAHE3/54 is AEC-Q101 qualified and manufactured with JESD 201 Class 2 whisker resistance, making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its –55 °C to +175 °C operating range, glass-passivated junction, and DO-41 package with UL 94 V-0 molding meet stringent automotive environmental and safety requirements.
How does the HE3 suffix differ from the E3 suffix in P4KE110CAHE3/54?
The HE3 suffix in P4KE110CAHE3/54 indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. Both share identical electrical specifications and DO-41 packaging, but HE3 is screened and tested to automotive reliability standards - including temperature cycling, highly accelerated life testing (HALT), and surge endurance - confirming suitability for mission-critical vehicle systems.
What is the standoff voltage (VWM) of the P4KE110CAHE3/54 and why is it important?
The P4KE110CAHE3/54 has a standoff voltage (VWM) of 94.0 V, meaning it remains in high-impedance state up to this DC or RMS voltage level. This value is critical because it must exceed the system's maximum normal operating voltage - for example, 24 V industrial buses or 12 V automotive supplies - to prevent leakage current, power loss, or false triggering during steady-state operation while still enabling rapid conduction during overvoltage events.
Can the P4KE110CAHE3/54 be used in bidirectional signal lines like RS-485 or CAN?
Yes, the P4KE110CAHE3/54 is explicitly designed for bidirectional applications, as indicated by the "CA" suffix. Its symmetrical breakdown and clamping behavior in both polarities makes it ideal for protecting differential communication lines such as RS-485, CAN, or LIN, where transients may appear as either positive or negative spikes relative to ground. No polarity marking is present, simplifying layout and eliminating orientation errors during assembly.
