Product details
Overview
P6KE68AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 68 V breakdown voltage (VBR = 64.6–71.4 V at IT = 1.0 mA), 92.0 V maximum clamping voltage at 6.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P6KE68AHE3/54 datasheet, P6KE68AHE3/54 pinout, P6KE68AHE3/54 application, or P6KE68AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 58.1 V stand-off voltage (VWM), 1.0 μA max reverse leakage at VWM, 20 °C/W junction-to-lead thermal resistance, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode operates as a voltage-clamping device that transitions from high-impedance standby to low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), while the DO-15 package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
The device is rated for 100 A non-repetitive forward surge current (IFSM) at 8.3 ms half-sine, 175 °C max junction temperature, and derates linearly above 25 °C ambient per Fig. 2. Its clamping behavior is defined by VC = 92.0 V at IPPM = 6.5 A, with 0.104 %/°C temperature coefficient of VBR, enabling predictable performance across automotive temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Surface-mount SMB package; 64 V VBR; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Requires PCB redesign for SMT placement; better suited for high-density layouts | Select SMBJ64A when board space is constrained and automated assembly is preferred. |
| 1.5KE68A | Same DO-15 package; higher 1500 W PPPM; 68 V VBR; larger junction area increases thermal mass | Higher surge margin but slower response due to larger junction capacitance | Choose 1.5KE68A where legacy designs require higher single-pulse immunity without layout change. |
Compared with SMBJ64A and 1.5KE68A, P6KE68AHE3/54 offers optimal balance of AEC-Q101 qualification, through-hole manufacturability, and precise 68 V clamping for cost-sensitive automotive and industrial protection - without requiring PCB revision or sacrificing reliability validation.

FAQ
What is the breakdown voltage range for P6KE68AHE3/54?
The P6KE68AHE3/54 has a guaranteed breakdown voltage range of 64.6 V to 71.4 V at 1.0 mA test current (IT), per Vishay Document 88369. This ±5% tolerance ensures consistent clamping onset across production lots and supports robust design margins in 48–60 V system rails. The value is measured under controlled 25 °C conditions and tracks with temperature via a 0.104 %/°C coefficient.
Is P6KE68AHE3/54 suitable for automotive applications?
Yes, P6KE68AHE3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Rev. 27-Sep-2021, Doc. 88369). Its qualification covers temperature cycling, high-temperature reverse bias, and ESD testing - making it appropriate for under-hood and cabin electronics such as body control modules and sensor interfaces. The HE3 suffix explicitly denotes AEC-Q101 compliance.
What is the maximum clamping voltage of P6KE68AHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE68AHE3/54 is 92.0 V at 6.5 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is specified in the Electrical Characteristics table and represents the upper limit of voltage seen by protected circuitry during standardized surge events - critical for ensuring downstream components remain within absolute maximum ratings.
Does P6KE68AHE3/54 have polarity marking, and how is it identified?
Yes, P6KE68AHE3/54 is unidirectional and features a cathode band (color stripe) on the body to identify the cathode terminal. As stated in the Vishay datasheet, "for unidirectional types the color band denotes cathode end." This marking aligns with industry-standard DO-15 orientation and must be observed during PCB layout to ensure correct circuit connection and clamping functionality.
What packaging format is used for P6KE68AHE3/54, and what is the reel quantity?
P6KE68AHE3/54 is supplied in 13" diameter paper tape and reel format with a base quantity of 4000 pieces per reel, as specified in the Ordering Information section of Vishay Document 88369. The "54" in the part number refers to the preferred package code for this reel configuration, and the "HE3" suffix confirms RoHS-compliant, AEC-Q101-qualified construction.
