Product details
Overview
P4KE75C-E3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 71.3 V minimum and 78.8 V maximum breakdown voltage at 1 mA test current, 64.1 V standoff voltage, 103 V maximum clamping voltage at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE75C-E3/54 datasheet, P4KE75C-E3/54 pinout, P4KE75C-E3/54 application, or P4KE75C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification (via HE3 suffix variant), low leakage (<1.0 μA at 64.1 V), and thermal resistance of 100 °C/W junction-to-ambient.
Technical Context
This device operates as a voltage-clamped overvoltage protection element, responding to fast-rising transients (nanosecond-scale) by transitioning from high-impedance to low-impedance state. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for consistent clamping under repetitive surge stress.
The bidirectional configuration enables symmetric suppression of positive and negative polarity transients without polarity sensitivity-ideal for AC-coupled or floating signal lines. Thermal performance is defined by RθJA = 100 °C/W and RθJL = 66 °C/W, supporting operation up to 175 °C junction temperature with derating above 25 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Surface-mount SMB package; same 75 V nominal breakdown; 600 W PPPM rating | Requires PCB rework for SMT layout; higher power handling but lower surge current density per mm² | Select when board space is constrained and automated assembly is required; verify thermal pad design for 600 W dissipation |
| P6KE75C | Higher 600 W PPPM rating; DO-15 package; identical VBR range and DO-41 footprint compatibility | Same through-hole mounting; better surge margin for infrequent high-energy events (e.g., industrial motor drives) | Choose for legacy DO-41-compatible designs needing enhanced energy absorption without layout change |
Compared with P4KE75C-E3/54, SMBJ75CA offers superior power density in SMT format but requires layout revision, while P6KE75C delivers 50 % higher pulse power in a mechanically compatible DO-41–sized package-making it ideal for drop-in reliability upgrades in existing through-hole systems.

FAQ
What is the breakdown voltage tolerance of P4KE75C-E3/54?
The P4KE75C-E3/54 has a specified breakdown voltage range of 71.3 V minimum to 78.8 V maximum at 1 mA test current, yielding a ±4.9 % tolerance about the nominal 75 V rating. This tight VBR distribution ensures predictable clamping onset across production lots and supports reliable system-level surge margin calculations in designs using P4KE75C-E3/54.
Is P4KE75C-E3/54 suitable for automotive applications?
The P4KE75C-E3/54 itself is RoHS-compliant commercial-grade; however, its AEC-Q101 qualified counterpart P4KE75CHE3/54 is explicitly validated for automotive use. For automotive designs requiring qualification, P4KE75CHE3/54 must be selected-both share identical electrical specs and DO-41 packaging, differing only in process control and test screening per P4KE75C-E3/54 documentation.
How does the bidirectional nature of P4KE75C-E3/54 affect its circuit placement?
Because P4KE75C-E3/54 is bidirectional, it provides symmetrical clamping for both positive and negative voltage transients without regard to orientation-no cathode marking is present. This allows direct placement across AC-coupled lines, transformer secondaries, or differential buses like RS-485, eliminating polarity concerns during assembly and simplifying layout for P4KE75C-E3/54 in mixed-signal systems.
What is the maximum clamping voltage of P4KE75C-E3/54 under surge conditions?
The P4KE75C-E3/54 exhibits a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events and is critical for verifying safe operating margins relative to downstream IC absolute maximum ratings in any design using P4KE75C-E3/54.
Does P4KE75C-E3/54 require a heatsink for normal operation?
No heatsink is required for P4KE75C-E3/54 under typical transient duty cycles (e.g., <0.01 % duty cycle per datasheet), as its 400 W pulse rating is defined for non-repetitive events. However, thermal design must account for RθJA = 100 °C/W; sustained power dissipation above 1.5 W (its rated DC power) will exceed TJ limits-so P4KE75C-E3/54 is intended strictly for surge suppression, not continuous power handling.
