Product details
Overview
P6KE68CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 68 V breakdown voltage (VBR min/max = 64.6–71.4 V), 58.1 V standoff voltage (VWM), 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 protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE68CA-E3/54 datasheet, P6KE68CA-E3/54 pinout, P6KE68CA-E3/54 application, or P6KE68CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (58.1 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across temperature.
Rated for 600 W peak pulse power (10/1000 µs), it sustains repetitive surges at 0.01 % duty cycle and handles up to 100 A non-repetitive forward surge (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C, with thermal resistance from junction to lead at 20 °C/W - critical for PCB trace heat sinking in high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V at 1.0 mA test current - defines precise avalanche onset window for reliable overvoltage triggering |
| VWM | 58.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 92.0 V at 6.5 A - clamping voltage during 600 W transient, limiting stress on protected ICs |
| PPPM | 600 W - peak surge power handling with 10/1000 µs waveform, enabling protection against lightning-induced or inductive-switching transients |
| IPPM | 6.5 A - maximum non-repetitive peak pulse current the device safely clamps without degradation |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive and industrial environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance allows effective heat transfer to PCB copper or heatsinked leads |

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 | DO-214AA package, 64 V VBR, 1000 W PPPM, lower RθJA (50 °C/W vs. 75 °C/W) | Higher power rating but larger footprint; better suited for board space-constrained designs needing >600 W headroom | Select SMBJ64CA when higher surge margin or surface-mount assembly is required; P6KE68CA-E3/54 remains optimal for through-hole cost-sensitive volume production. |
| P6KE68A-E3/54 | Unidirectional variant with identical VBR/VC/PPPM, cathode band marking, 3.5 V VF at 50 A | Requires correct polarity placement; suitable only where DC bias direction is fixed and reverse conduction must be blocked | Choose P6KE68A-E3/54 only for unidirectional DC rails; P6KE68CA-E3/54 is mandatory for AC-coupled, differential, or floating signal lines. |
Compared with SMBJ64CA and P6KE68A-E3/54, P6KE68CA-E3/54 uniquely balances DO-15 through-hole manufacturability, bidirectional symmetry, UL/IEC compliance readiness, and AEC-Q101-qualified variants - making it the preferred choice for legacy-compatible, high-volume industrial and automotive power-line protection.

FAQ
What does the "CA" suffix indicate in P6KE68CA-E3/54?
The "CA" suffix in P6KE68CA-E3/54 denotes bidirectional construction, meaning the device provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses, or floating power domains without polarity sensitivity. Unlike unidirectional variants (e.g., P6KE68A), P6KE68CA-E3/54 has no cathode marking and conducts identically in either direction above its breakdown threshold.
Is P6KE68CA-E3/54 AEC-Q101 qualified?
No - P6KE68CA-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade qualification per JESD 201 Class 1A whisker testing. For AEC-Q101 qualification, the HE3 suffix variant (e.g., P6KE68CAHE3/54) must be selected; that version undergoes full automotive stress testing including temperature cycling, humidity bias, and accelerated life validation.
What is the maximum clamping voltage of P6KE68CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE68CA-E3/54 is 92.0 V at 6.5 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range (–55 °C to +175 °C).
Can P6KE68CA-E3/54 replace P6KE68A-E3/54 in an existing design?
No - P6KE68CA-E3/54 cannot directly replace P6KE68A-E3/54 without layout review. While both share identical VBR, VC, and PPPM, the unidirectional P6KE68A-E3/54 requires correct cathode orientation and blocks reverse current, whereas the bidirectional P6KE68CA-E3/54 conducts equally in both directions. Substitution may cause unintended conduction paths in DC-biased circuits.
What is the thermal resistance from junction to ambient for P6KE68CA-E3/54?
The typical thermal resistance from junction to ambient (RθJA) for P6KE68CA-E3/54 is 75 °C/W under standard JEDEC test conditions (single device on FR-4 board, 1 in² copper pad). However, its junction-to-lead resistance (RθJL) is 20 °C/W - meaning effective thermal performance depends heavily on PCB copper area connected to leads, especially for sustained surge duty cycles.
