Product details
Overview
P4KE62C-E3/73 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 a 62 V breakdown voltage (VBR min/max = 58.9–65.1 V), 400 W peak pulse power (10/1000 µs), and clamps to ≤85.0 V at 4.7 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE62C-E3/73 datasheet, P4KE62C-E3/73 pinout, P4KE62C-E3/73 application, or P4KE62C-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility with through-hole PCB assembly, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for transient energy dissipation in automotive-grade designs.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure, responding in <1 ns to fast transients such as ESD or inductive switching spikes. Its bidirectional configuration enables symmetrical clamping across both polarities without polarity marking, making it suitable for AC-coupled or floating signal paths.
The P4KE62C-E3/73 complies with AEC-Q101 stress testing for automotive applications and uses glass-passivated chip construction for stable VBR tolerance and low incremental surge resistance. Its 10/1000 µs waveform rating reflects standardized surge immunity testing per REA definitions, with derating applied above TA = 25 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines guaranteed clamping onset range under specified test current |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤85.0 V at 4.7 A - peak clamped voltage during 400 W transient, limiting downstream IC stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Surface-mount SMB package; same VBR range (60.8–67.2 V); 600 W PPPM; lower RθJA (50 °C/W) | Requires rework for SMT-only PCBs; better suited for high-density telecom modules | Select when board space is constrained and automated assembly is preferred over through-hole |
| 1.5KE62CA | Same DO-41 package; higher PPPM (1500 W); larger junction capacitance (150 pF vs. ~50 pF); VC = 101 V @ 14.3 A | Used where higher single-event energy must be absorbed, e.g., main power input stages | Choose for higher-energy threats but verify downstream IC withstand capability given higher clamping voltage |
Compared with SMBJ64CA and 1.5KE62CA, the P4KE62C-E3/73 offers optimal balance of proven through-hole reliability, AEC-Q101 qualification, and precise 400 W clamping performance for cost-sensitive automotive and industrial signal-line protection - without requiring layout changes or sacrificing surge margin.

FAQ
What does the "C" suffix indicate in P4KE62C-E3/73?
The "C" in P4KE62C-E3/73 denotes bidirectional configuration - meaning the device provides symmetrical clamping for both positive and negative transients without polarity marking. This distinguishes it from unidirectional variants like P4KE62A-E3/73, which feature a cathode band and conduct only in reverse bias. The P4KE62C-E3/73 is functionally identical to P4KE62CA in Vishay's naming convention.
Is P4KE62C-E3/73 qualified for automotive applications?
Yes, P4KE62C-E3/73 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P4KE62CHE3/73). The standard E3 suffix indicates RoHS-compliant commercial grade; for automotive use, confirm ordering code includes HE3 and verify qualification documentation from Vishay's official datasheet revision 16-Sep-2021 (Doc. #88365).
What is the maximum clamping voltage of P4KE62C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P4KE62C-E3/73 is 85.0 V at 4.7 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet and represents the upper bound of voltage seen by protected circuitry during a standardized transient event.
Can P4KE62C-E3/73 replace P4KE62A-E3/73 in a design?
No - P4KE62C-E3/73 is bidirectional while P4KE62A-E3/73 is unidirectional. Substituting them requires verifying circuit polarity, grounding scheme, and transient directionality. Unidirectional types have a cathode band and conduct forward current; bidirectional types lack marking and clamp both polarities. Using P4KE62C-E3/73 in place of P4KE62A-E3/73 may cause unintended conduction in DC-biased lines.
What is the thermal resistance specification for P4KE62C-E3/73?
The P4KE62C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with leads held at 75 °C. This parameter governs how effectively heat from transient energy dissipation transfers from the silicon junction to the PCB leads, directly influencing safe surge repetition rate and layout copper requirements.
