For engineers reviewing the P6KE75-E3/54 datasheet, P6KE75-E3/54 pinout, P6KE75-E3/54 application, or P6KE75-E3/54 equivalent, this page delivers verified electrical parameters, DO-204AC package details, clamping behavior under surge conditions, thermal resistance data (RθJL = 20 °C/W), and AEC-Q101 qualification status for automotive-grade reliability assessment.
Technical Context
The P6KE75-E3/54 implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1 ns) and low dynamic impedance during surge events. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, with thermal derating defined per Figure 2 and power dissipation limited to 5.0 W on infinite heatsink at TL = 75 °C.
It complies with ANSI/IEEE C62.35 surge test standards and meets UL 497B recognition (QVGQ2, E136766) for protector classification. The device is RoHS-compliant (E3 suffix), JESD201 Class 1A whisker-tested, and rated for 100 A non-repetitive forward surge current (8.3 ms half-sine).
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 |
|---|---|---|---|
| SMBJ75A | DO-214AA package; 75 V VBR min; 600 W rating; RθJA = 40 °C/W (vs. 75 °C/W for P6KE75-E3/54) | Better thermal performance in SMT layouts; requires PCB pad redesign vs. through-hole DO-15 footprint. | Select SMBJ75A for space-constrained SMT designs where leaded assembly is not feasible. |
| 1.5KE75A | Same DO-204AC package; identical VBR, VC, and PPPM; but rated only for commercial grade (not AEC-Q101) | Lacks automotive qualification; suitable for consumer/industrial use where extended temperature validation is not required. | Choose 1.5KE75A for cost-sensitive non-automotive applications with identical electrical behavior. |
Compared with SMBJ75A and 1.5KE75A, the P6KE75-E3/54 uniquely combines AEC-Q101 qualification, through-hole DO-15 mechanical robustness, and 20 °C/W junction-to-lead thermal resistance - making it optimal for high-reliability automotive and industrial power entry points where manual rework or vibration resistance matters.

FAQ
What is the clamping voltage of P6KE75-E3/54 at its rated peak pulse current?
The P6KE75-E3/54 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The P6KE75-E3/54 maintains this clamping performance across its specified operating temperature range.
Is P6KE75-E3/54 suitable for automotive applications?
Yes, the P6KE75-E3/54 is AEC-Q101 qualified (per note "(1)" on page 3 of Vishay document 88369), confirming its suitability for automotive powertrain and body electronics. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and UL 497B recognition (E136766) support deployment in engine control units, lighting modules, and infotainment power supplies where reliability under thermal and electrical stress is critical. The P6KE75-E3/54 meets these requirements out-of-the-box.
What does the "E3/54" suffix mean in P6KE75-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "/54" denotes the preferred package code for 13-inch paper tape and reel packaging with a base quantity of 4000 units. This ordering format ensures consistent traceability and automated assembly compatibility. The P6KE75-E3/54 is distinct from the HE3 variant, which adds AEC-Q101 qualification - though the E3 version itself is already AEC-Q101 qualified per Vishay documentation.
How does P6KE75-E3/54 compare to P6KE75A in terms of specifications?
The P6KE75-E3/54 and P6KE75A share identical electrical characteristics - including VBR (71.3–78.8 V), VWM (64.1 V), VC (103 V), and PPPM (600 W) - because the "E3/54" suffix specifies packaging and compliance attributes, not parametric changes. Both use DO-204AC (DO-15) packaging and meet the same thermal and surge ratings. The P6KE75-E3/54 is the exact orderable part number reflecting Vishay's standard commercial-grade, RoHS-compliant, tape-and-reel configuration.
Can P6KE75-E3/54 be used in bi-directional protection circuits?
No - the P6KE75-E3/54 is a unidirectional TVS diode, as confirmed by its "A" suffix (e.g., P6KE75A) and cathode band marking. For bi-directional applications, Vishay specifies the "CA" suffix (e.g., P6KE75CA). Using the unidirectional P6KE75-E3/54 in AC or symmetrical transient environments risks forward conduction during negative half-cycles, potentially causing failure. Always match polarity: P6KE75-E3/54 for DC rail clamping, P6KE75CA-E3/54 for signal line or AC-coupled protection.
