Product details
Overview
P4KE11CAHE3/54 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 11 V breakdown voltage (VBR min/max = 10.5–11.6 V at 1.0 mA), 9.4 V standoff voltage (VWM), 15.6 V clamping voltage (VC) at 25.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect automotive sensor interfaces against ESD and load dump.
For engineers reviewing the P4KE11CAHE3/54 datasheet, P4KE11CAHE3/54 pinout, P4KE11CAHE3/54 application, or P4KE11CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and low leakage (<5.0 μA at VWM).
Technical Context
This device operates as a voltage-clamping protection element in bidirectional configurations, responding to transient overvoltages in either polarity without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the DO-41 package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002.
Rated for -55 °C to +175 °C junction temperature range and qualified per AEC-Q101, the P4KE11CAHE3/54 delivers repeatable surge suppression under automotive-grade reliability requirements. Its 1.5 W steady-state power dissipation and 66 °C/W junction-to-lead thermal resistance enable direct PCB mounting without heatsinking for moderate-duty transient events.
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 |
|---|---|---|---|
| SMBJ11CA | Surface-mount SMB package; same VBR (10.5–11.6 V), lower PPPM (600 W), higher IPPM (53.3 A) | Requires PCB redesign for SMT placement; better suited for high-density layouts with automated assembly | Select when board space is constrained and reflow compatibility is required; not pin-compatible with DO-41 footprint |
| 1.5KE11CA | Same DO-41 package; higher PPPM (1500 W), higher VC (19.0 V), larger junction capacitance | Used where higher surge margin is needed (e.g., alternator load dump), but increases clamping voltage stress on protected ICs | Choose for heavy-duty industrial power inputs; avoid in low-voltage logic protection due to elevated clamping level |
Compared with SMBJ11CA and 1.5KE11CA, the P4KE11CAHE3/54 offers optimal balance of AEC-Q101 qualification, proven DO-41 reliability, and tight 15.6 V clamping - making it preferred for cost-sensitive, through-hole automotive and industrial designs requiring validated field performance.

FAQ
What does the "CA" suffix indicate in P4KE11CAHE3/54?
The "CA" suffix denotes a bidirectional configuration - meaning the P4KE11CAHE3/54 clamps voltage transients of either polarity symmetrically, with no cathode marking on the DO-41 package. This distinguishes it from unidirectional variants (e.g., P4KE11A) that require correct orientation during placement and feature a band-marked cathode end.
Is P4KE11CAHE3/54 suitable for automotive applications?
Yes, the P4KE11CAHE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance to automotive reliability standards. Its -55 °C to +175 °C operating range, glass-passivated junction, and 400 W surge rating make it appropriate for engine control units, body electronics, and ADAS sensor protection circuits where transient immunity is critical.
How does the clamping voltage of P4KE11CAHE3/54 compare to its breakdown voltage?
The P4KE11CAHE3/54 has a breakdown voltage range of 10.5–11.6 V at 1.0 mA and clamps at 15.6 V when subjected to its rated 25.6 A peak pulse current. This 1.43× clamping ratio ensures predictable overvoltage limiting while maintaining sufficient margin below typical 16 V absolute maximum ratings of protected ICs.
What is the significance of the "HE3/54" in P4KE11CAHE3/54?
The "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 5500 units - standard for automated through-hole insertion equipment and consistent with Vishay's ordering nomenclature.
Can P4KE11CAHE3/54 replace P4KE11A in an existing design?
No - P4KE11CAHE3/54 is bidirectional while P4KE11A is unidirectional; substituting them requires verifying circuit topology. The P4KE11A has a cathode band and conducts forward current, whereas the P4KE11CAHE3/54 has no polarity marking and clamps both polarities. Direct replacement may cause malfunction in DC-biased lines or rectifier-based protection schemes.
