Product details
Overview
P4KE62-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and surge transients. It features a 58.9 V minimum breakdown voltage (VBR), 53.0 V standoff voltage (VWM), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines of automotive sensor modules.
For engineers reviewing the P4KE62-E3/54 datasheet, P4KE62-E3/54 pinout, P4KE62-E3/54 application, or P4KE62-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 66 °C/W), unidirectional polarity marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS operates as a voltage-clamping device triggered by transient overvoltage events exceeding its reverse standoff voltage (53.0 V). Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, ensuring effective suppression of 10/1000 μs surges up to 400 W without thermal runaway.
The device is rated for -55 °C to +175 °C operating junction temperature, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Its unidirectional configuration uses a cathode band marking and exhibits 3.5 V forward voltage at 25 A, consistent with P4KE220A and lower-voltage variants per specification note (3).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | DO-214AA package, 60 V VWM, 96.8 V VC @ 4.1 A, 600 W PPPM | Higher clamping voltage but higher surge rating; surface-mount only | Select when board space is constrained and PCB layout supports SMD placement with adequate thermal relief. |
| 1.5KE62A | DO-201AD package, same VWM/VBR specs, 1500 W PPPM, higher IPPM (24.5 A) | Larger footprint and higher surge capacity; through-hole compatible but heavier | Choose for legacy through-hole designs requiring higher single-pulse robustness without changing mounting method. |
Compared with SMBJ60A and 1.5KE62A, the P4KE62-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, and precise 53.0 V standoff for 12 V automotive systems - making it preferred where RoHS-compliant DO-41 compatibility and proven field reliability are prioritized over raw power rating or SMT density.

FAQ
What is the clamping voltage of the P4KE62-E3/54 under a 10/1000 μs surge?
The P4KE62-E3/54 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is measured per Figure 1 and Table 1 in Vishay document 88365. The P4KE62-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the P4KE62-E3/54 qualified for automotive applications?
Yes, the P4KE62-E3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 16-Sep-2021 (document 88365), footnote (1) under Ratings and Characteristics Curves. This qualification validates its reliability for use in automotive powertrain, body control, and ADAS systems. The P4KE62-E3/54 meets stress test requirements including temperature cycling, humidity bias, and mechanical shock - essential for under-hood and cabin-mounted electronics.
What does the "E3/54" suffix indicate in P4KE62-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 5500 units. This ordering format aligns with Vishay's standard delivery mode for DO-41 devices and ensures compatibility with automated pick-and-place equipment. The P4KE62-E3/54 is distinct from HE3-suffixed variants which carry AEC-Q101 qualification.
How does the P4KE62-E3/54 differ from bidirectional TVS diodes like P4KE62CA?
The P4KE62-E3/54 is unidirectional and features a cathode band for polarity identification, whereas P4KE62CA is bidirectional with no marking and symmetrical clamping in both directions. Unidirectional operation allows lower leakage current (1.0 μA at VWM) and better performance on DC-biased lines. The P4KE62-E3/54 is intended for applications such as 12 V power rail protection where polarity is fixed and reverse conduction must be blocked.
What is the thermal resistance from junction to lead for the P4KE62-E3/54?
The P4KE62-E3/54 has a typical thermal resistance from junction to lead (RθJL) of 66 °C/W, as specified in the Thermal Characteristics table of Vishay document 88365. This parameter is critical for estimating junction temperature rise during repetitive surge events and informs PCB copper pour design around the DO-41 leads. The P4KE62-E3/54 relies on lead conduction rather than case convection for heat dissipation, making lead length and pad thermal mass key layout considerations.
